EXPERIENCE COUNTS

Words from the IACDS President Well stuffed like a thanksgiving turkey A fantastic industry

Photo: Vito Gogola.

Dear readers It is amazing how time flies. When you get this issue in your hands Christmas is just around the corner. Many of us just wish that this year should end and are hoping for positive changes during 2014. The world is limping in many parts, Europe in particular.

Business is weak and has been for quite a while.

But judging from this issue of PDi things doesn’t look that bad anyway. We have received positive news from many parts of the world showing that even if the wheels are spinning a bit slower they do spin. And it seems like they are accelerating. This issue is packed with interesting news, reports and special features. We are in this issue publishing our popular annual concrete floor grinding and polishing feature with news about new products and stories from several corners of the world. In the feature you can among others read about how the interest for concrete floor polishing is picking up in China. I think we have just scratched the surface when it comes to floor preparation and concrete floor polishing. The potential is enormous. Attached to the feature you can read about the Brazilian manufacturer of floor grinding equipment LVS, yet rather unknown to the rest of the world but claims to have about 50% of the Brazilian market. PDi’s Brazilian correspondent Luiz Carlos Beraldo reports.

Another interesting news for the European concrete floor grinding market is that US manufacturer of concrete floor grinding and polishing equipment, Superabrasives, has taken a solid step to market its products in Europe. We hope to report more on Superabrasives’ activities in Europe in the coming issues of PDi. In this issue we are also publishing special features on floor sawing equipment and hydrodemolition equipment. A big news attached to the hydrodemolition feature is the fact that the manufacturer Conjet has broken its silence and is about to launch several novelties at World of Concrete next year. The biggest news is probably their new hydrodemolition unit Robot 557.

PDi has also attended the South African trade show Bauma Africa that was recently organised for the first time in South Africa. PDi’s African correspondent Jessica Hannah reports.

We also publish a number of other interesting reports like a story about Husqvarna Construction Products’ activities in China and a report about the demolition and concrete swing and drilling market in Hong Kong. Hong Kong is really booming now and has been for a number of years. A lot of new projects are planned for the coming years so no one believes that a recession is approaching for another two to three years.

That is like music in my ears when so many other parts of the world are struggling with recession and the serious effects of it.

In this issue you also find a lot of information from our associations related to demolition and concrete sawing and drilling. At the international umbrella association IACDS annual meeting in Munich in April the association received rather strong critics for not delivering. This resulted in the decision to call for an extra meeting about the future of IACDS. This meeting was held in Amsterdam in September and I attended it myself. In this issue you can read about what was discussed at the meeting and what decisions where taken. That was some examples of what you can read about in this issue, which is, as usual stuffed, to he limit, like a thanksgiving turkey, with interesting and comprehensive articles made by our skilled staff. I am proud to say that and I hope you like what you are reading in this magazine and that it is helpful in your work.

Next issue will reach your desk some time in the beginning of next year, some weeks before the US show World of Concrete. I therefore take the chance to wish you all a Merry Christmas and a great end of the year.

PDi • Issue 5 • 2013

Jan Hermansson Editor-in-Chief jan.hermansson@pdworld.com

When I was appointed chairman of the International Association of Concrete Drillers and Sawers half a year ago I wrote in my first column in PDi ‘What a great industry’. That could be the introduction in all of my coming columns. I must say that I like this industry. It is fantastic.

A few weeks ago I visited Helsinki together with some Swedish member companies. The agenda included a visit to Kuusakoski’s recycling station and a first informal meeting with the Finnish branch association.

The visit to the recycling station was exiting.

In one end of the station a bucket of unidentified waste was feed into the system. The waste then passed through a modified crusher and screening station with several separating units. After each step a portion of the waste was fed into a container. The material then was transported on belts where it was treated with water, magnets and air and checked in order to separate it. All material was then collected in piles to be burned, sold, recycled or sent to landfill.

The majority of this process was automatic with a minimum of people involved. The area was cleaned thoroughly every day and the floor was like a dining room floor with absolutely no waste on it and very clean.

I made a similar visit to a recycling plant in Denmark 10 years ago. The recycling plant in Denmark was known to be a state of the art facility at that time. But my impression from that visit was that the plant was very labour intensive and involved a lot of people. Also the working environment had a lot of potential for improvement.

In 10 years a lot of has happened in our industry. Development travels fast and I am very happy to be part of it. It is great to meet all these member companies that with great enthusiasm follow development and in many cases also lead it. To lead it is important to absorb common knowledge, find new trends and create new applications of your own. I think that to collect new trends and manners, how you work, and also share your knowledge with colleagues is sometimes easier between companies from different nations. I believe that local companies that compete on their home market are more limited. Maybe it is, for instance, easier for Finnish companies to share their knowledge with the Swedes, as they do not compete in the same market. It is also important to move this industry

forward, to share knowledge. Some countries have come further in some areas than other countries, so why not share?

At our recent IACDS meeting in Amsterdam it was decided that each member association should document and present why this association has become particularly good in a certain area. The member association will make a report, which will be produced, from the member associations’ own experiences, law and regulations.

Then it is up to all other member associations in IACDS respectively to adapt or modify the report to their own provisions. For example Sweden is rather good in handling quartz and silicosis and has a special knowledge in this area. We will make a report in English about how we handle and work with this here in Sweden. The report will be distributed to all other IACDS members.

The receiving member country can then modify the report for their own local purposes. It can for instance be different limits and levels of dust that the report needs to be amended. By putting this in process IACDS and its members can easily develop its skills.

We take what we know someone is good at, maybe best at, we modify it for our own country and we are able to lift our level of competence.

That is what I call progress.

If there is something this industry has always been doing it is to develop. Now with what has been decided within IACDS in Amsterdam we are going to speed up that progress. Isn’t that great? Is this not a great industry? An article about what was decided at the IACDS meeting in Amsterdam is published in this issue. PDi will continue to report on IACDS new strategy and work in future issues of the magazine.

Chicago Pneumatic appoints distributor in Australia International construction equipment manufacturer Chicago Pneumatic has appointed Redstar Equipment as its national distributor of diesel powered portable compressors in Australia. “We are pleased to welcome Redstar Equipment to our global distributor network,” said Chicago Pneumatic business development vice president Andrew Cope. “We believe our products offer high levels of reliability and performance, and Redstar Equipment will allow us to reach Australian customers more efficiently and effectively.

Their knowledgeable team can successfully provide customers in the construction, mining, rental and associated industries with practical and cost effective compressed air solutions.”

Redstar, based in Rocklea, Queensland, specialises in importing and distributing diesel compressors, generators and welders for the Australian industrial, mining and construction sectors. With a wide range of portable compressors, CP has proved to be a good choice for the company. “We are excited to have been appointed as an authorised Chicago Pneumatic distributor,” said Redstar general manager Kevin Ennis, “Chicago Pneumatic products offer excellent value for money which fit in line with the ‘designed and built for reliable performance’ philosophy of the brand.” As part of its agreement with CP, Redstar will also provide customer solutions for a variety of compressor applications.

The US firm Bechtel, which leads the BACS consortium, will design and build two lines with a total distance of 63.3km, while the Spanish firm FCC Construccion heads up the FAST consortium delivering three lines for a distance of 72.5km.

“We plan to create a new cultural heritage and tourism route, beginning from the King Abdulaziz Historical Centre to the Government Palace,” said commission member Al-Sultan.

Some 3,088 development projects worth $74bn (EUR55bn) are being implemented in different parts of Riyadh region and 62 agencies have been authorised to follow up on the implementation of the projects. These agencies will also generate proposals for the development of the region and ways to resolve obstacles facing development. In addition, they will present regular progress reports to the RDHC. Earlier, the rules and regulations for the development of Wadi Hanifa and surrounding valleys were approved by the RDHC. The project aims to make use of the area as a tourist and amusement centre, while preserving its agricultural and heritage sites.

The EDA was invited by the European Commission to participate in the conference, and gave a presentation ‘Developing an economy on C&D waste’ as part of the session ‘Promoting life-cycle thinking’.

The demolition industry must do innovation all the time and quoting the title of this column, innovation is our routine. This is because our work requires different approaches every day, because of the site, the waste and the requirements of the project. Nobody plans to make it easier

Wacker Neuson at Bauma Africa Wacker Neuson was represented at the first Bauma Africa displaying a comprehensive range of products and services. As a growth market, the continent plays an important role for the Wacker Neuson Group. “Africa is a market with great potential,” said Wacker Neuson chied executive officer Cem Peksaglam. “We are already represented in several African countries with our range of light construction equipment, and have enjoyed particular success with our equipment for soil compaction, as well as in the field of concrete technology. However, we feel that we can generate more demand for both our light and compact equipment ranges by selling products that are even better tailored to the needs of local customers.”

The application centre and Zaxis mini excavator factories have merged into one operation, which will have far-reaching benefits for the company. “At first glance, there is no similarity between Hitachi mini excavators and special application machines,” said Oosterhout factory general manager Tonny Engels. “However, we have successfully aligned these diverse product categories by combining the skills of our workforce for the production, painting and assembly processes.

Our priority is to increase the level of localisation in response to market demand and this is the main reason for the reorganisation of the facilities in Oosterhout.”

Genesis Attachments appoints national account manager In the US Genesis Attachments has appointed Blaine Archibald as national account manager.

Archibald, who was previously Genesis Southwest regional manager, will develop, manage and maintain a national account programme focusing on the scrap industry. He will also continue in his regional manager role until a successor is named.

Hilti continues profit recovery The Hilti Group achieved a moderate increase in sales of 2.6% over the first eight months of 2013.

Over the same period, the company was able to boost its operating result by 62.7%, making a significant step to recover its profitability.

Sales in Swiss francs were 2.6% higher than in the same period last year, with total recorded sales of CHF2,859M (EUR2,324M).

Sales performance was negatively influenced by increasingly volatile currency developments in individual growth markets. Growth in local currencies amounted to 3.1%. Consistent implementation of the productivity enhancement and cost-cutting programme has raised net income by 95.4% to CHF203M (EUR165M). The operating result was CHF292M (EUR237M) up 62.7% on last year’s figure.

In percentage terms, Hilti Group continues to anticipate sales growth in the low single-digit range for the full year 2013, along with ongoing significant increases in profitability and a return on sales of between 9% and 10%.

New recruits for RVA Group The engineering consultancy RVA Group has appointed three new project managers Rashid Shauq, James Armstrong and Keith Kirby as it continues to expand operations in the UK and across the globe. All are professional engineers with many years experience of working in high hazard sectors, including the oil and gas, chemical, pharmaceutical and manufacturing industries.

RVA Group specialises in decommissioning, decontamination, dismantling and demolition projects. Its growing client portfolio includes companies such as Total, ConocoPhillips, INVISTA, GSK, Bayer, INEOS, Huntsman and BASF. “The nature of our work means we hand pick the very best and most talented individuals in our sector,” said RVA managing director Richard Vann. “All of our three new project managers have considerable knowledge of the markets we serve and they will be a great addition to the RVA team as it continues to expand, winning new international projects, as well as ensuring it maintains the leading position in the UK, which is equally important to us.”

RVA has used the last year trading through the global recession whilst at the same time, investing heavily in its personnel training, quality management systems and IT infrastructure, as it prepares to build on its solid position. The move is seen as crucial to supporting and sustaining the business on an international platform and continuing to meet its clients’ demands.

“This investment is considerable and absolutely necessary as our international work in particular needs to be supported by a strong corporate infrastructure that operates efficiently around the clock and across multiple time zones,” said Vann. “Our reputation for the delivery of safe, secure and best value engineering projects has grown steadily over the last few years and this in turn has helped increase the number of overseas assignments both for existing and new clients. It’s a reputation well deserved by our hard working, highly experienced and innovative team.”

Volvo CE divests dealership Volvo Construction Equipment has divested its wholly owned Salzburg-based Central Europe Group to long-term distribution partner Ascendum Group for an undisclosed sum. The deal includes the Austrian-owned group of companies and Volvo CE’s business in Romania, which also includes Moldova. The Austrian company’s subsidiary dealerships and territories in Bosnia-Herzegovina, Croatia, the Czech Republic, Hungary, Slovakia and Slovenia are also included in the transaction.

Ashine granted 27 patents The Chinese diamond tool manufacturer Ashine Diamond Tools has been granted 27 patents of community design from The Trade Marks and Designs Registration Office of The European Union. The patents include diamond tools for surface preparation, grinding, polishing and floor maintenance. It demonstrates the leading research and development capability of Ashine, and its determination to be a grinding and polishing expert to serve the highest needs of the industry worldwide.

“It’s important for Ashine to focus on grinding and polishing technologies,” said Ashine president Richard Deng. “This allows Ashine to continually provide better solutions to meet challenges faced by our clients around the world. We continually invest in research and development to develop better tools to propel the industry forward.”

Ashine has been dedicated to grinding and polishing technologies for the past 20 years and is committed to be the leading manufacturer of grinding and polishing diamond tools. With the continuous effort of its research and development team and cooperation with three universities, Ashine has achieved success in providing a full range of diamond tools for the industry.

Ritchie Bros seeks new CEO The auctioneers Ritchie Bros has announced that chief executive officer Peter Blake will step down in May 2014, at the time of the company’s next annual general meeting. During the interim period he will continue to lead the company while the Board searches for a replacement. Blake joined Ritchie Bros. in 1991 and has been CEO since 2004. Under his leadership the company has grown to become a global leader in the industrial equipment exchange business, expanding into new markets with a track record as a leading innovator in the industry.

Hilti among top worldwide employers Hilti has been placed 15th in the recent international employer evaluation conducted by the US based Great Place to Work Institute, giving the company a top ranking among the world’s best companies.

In 2011 Hilti was ranked 15th. The company’s proven strengths help separate Hilti from other top finishers. “The level of trust in management is particularly strong, placing Hilti significantly above the average of the best five companies in the world,” said Great Place to Work Institute representative Otto Zell. Fairness and employee motivation are also particularly strong at Hilti. The company has again shown that its serious attitude towards corporate culture is not merely based on location, but must be lived out and implemented on a worldwide basis. The international evaluation of the Great Place to Work Institute has shown

12 PDi • Issue 5 • 2013

that the values-oriented climate is present at Hilti around the globe. Hilti invests some CHF7.6M (EUR6.15M) annually in corporate culture workshops that involve all 21,000 employees.

“China is Amazing” Husqvarna Construction Products has a long established manufacturing base in China and been selling its products there for many years. PDi editor Jan Hermansson assess the company’s progress.

China, which has the world’s largest population with more then 1.3bn people, has had a big impact on the rest of the world. Over the past 40 years or so the country’s low cost manufacturing has changed the rules in the world’s market economy, which initially made many western companies fear they would loose business.

But with China being more open foreign companies have started local manufacturing, and has become an increasingly common trend. When this initially started the purpose of the manufacturing was mainly for export and to stay competitive in the western world. But with a

rapidly growing domestic market and purchasing power in China the situation has changed.

Husqvarna and China Foreign companies view China as a very important market and one company that has realized the potential, is Husqvarna Construction Products, which has been present in China with its own production plants for many years, not counting Diamant Boart, which Husqvarna purchased in 2002, and which had own plants in China since 1995.

Head office for Husqvarna Construction’s operations is Xiamen in the province of Fujian. Husqvarna Construction`s managing director for China over the past five years is Marc Segers, who is Belgian and has a background with Diamant Boart. Segers has been in this organization for 27 years and has worked for Diamant Boart and Husqvarna all over the world. He spent several years in the US when the company Target was purchased. “I am really proud of our operations here in China and in particular our staff. We are simply the best,”said Segers, “the Xiamen facility has made tremendous progress over recent years, by 2014 we want to be the best factory in our industry.”

Greg Wu is production and logistics manager in Xiamen and a specialist in the Lean production process that is fully implemented and continuously monitored at the Xiamen factory since 2009. Lawrence Liu is sales and marketing director for Husqvarna’s construction division in China and located in Beijing.

Besides this young vibrant team 100 employees work in the production at the Xiamen factory and another 25 employees in sales. About 19 people work entirely with quality control and Wu guarantees that all products leaving the factory are 100% checked and tested. “The quality of our products is always our top priority, along with ensuring they are delivered on time,”said Wu. “ no product can leave the factory without being 100% according to customer`s specification, is our rule.”

The products manufactured in Xiamen are tile and masonry saws, which started in 2004. Since then, several floor saws, drill stands, grinders and dust collectors were industrialized in the Xiamen factory.

“A stable work force and excellent engineers have made it possible for the factory to take on more and more challenging products,” added Segers.

Besides complete products, the Xiamen factory also produces accessories and components for other factories within Husqvarna Construction. Parts that are used in the products are sourced from suppliers

“Naturally all parts that we purchase are controlled just as strictly as the machines, we produce ourselves,”said Wu. “We have good capacity here in Xiamen and we are just using part of it. By 2014 we will reach some 35,000 units/year.”

Wu said that all suppliers are also involved in the Lean production principles and each is rated monthly.

If there is a quality problem it is dealt with directly. The factory has followed the Lean system since 2009 and this year also the Husqvarna sales unit in China is working according to Lean. English is the official language in the Xiamen factory, which is certified according to ISO 9001 and ISO 14001 since 2010.

In 2006 Husqvarna started a joint venture together with the Chinese company Jikai Industrial Group and in 2012 Husqvarna became full owner of this Husqvarna-Jikai JV and the business name changed to Husqvarna Hebei.

Initially, Jikai manufactured diamond tools for the domestic Chinese hardware market and for the export.

This year, Felker, an existing Husqvarna owned brand, was launched to further develop the sales to the Chinese hardware market. Segers is now also head of the operations in Shijiazhuang, which employs about 500 people.

“Our factory in Hebei was quite a challenge to take on the responsibility for, but we are well on the way to develop this larger organization into the Husqvarna procedures and culture. I see also a great demand not only for Husqvarna diamond tools but also for the Felker diamond tools for the hardware market in China and Asia as a whole,”said Segers. “In the past, the vast majority of the production was exported mainly to USA and Europe. Today we also see increased deliveries to other Asian markets not just China. Asia has

huge potential for us and our factory here in Xiamen, in the south of China, is the perfect hub.” Although the factory in Xiamen is a short distance from the harbor, Husqvarna also has a warehouse in the port. “It allows us the deliver fast, anywhere in Asia,” Segers added.

Gaining market ground The sales team in China, with Lawrence Liu as head of sales and marketing for the construction sector in China, has the full Husqvarna Construction products portfolio to offer. The sales are gathered in a separate unit, which has 25 employees. The strongest business sector for Husqvarna is currently the rescue industry with the Husqvarna power cutters. “We have a very strong foothold and clearly the market leader in this sector. Our products are the most used in the country in terms of rescue operations. But we are steadily gaining ground in the construction sector, which also has the biggest potential, but the strongest competition,” said Liu. Husqvarna has a strong network of dealers in China selling their complete range, some of them act as authorised service centres. On top of this Husqvarna has their own service and training facilities in Beijing, Shanghai and Xiamen. The target is to triple the number of service centres within the next three years. “Our development in the Chinese market has been quite fast. Just a few years ago we had just one person working on the domestic market. Today we have a completely new organisation of 25 people,” said Liu. The new sales organisation is divided in the segments of construction dealers, rescue and Heavy users.

The Heavy User team focus on the marketing of wall saws, wire saws, floor grinders and demolition robots. They are supported by a team of service and demonstration specialists.

Liu said that it takes a bit more time to sell the concept of using wall and wire saws and particularly demolition robots in China. These products cost more, and more training and knowledge is required. It takes more to explain the benefits and how a wall or wire saw, floor grinder and a demolition robot works before there is action from the market. “But as soon as clients understand what these products offer and what the benefits are the implementation gets so much easier,” said Liu. So far the Husqvarna power cutters are the most well-known product in China and have a strong reputation within the rescue and railway customers. “The potential for these products for construction application is huge,” said Liu. Concrete floor grinding is growing also in China and there are many brands in the country.

The Husqvarna remotely controlled demolition robot program has been well received within the process industry but is taking time to be accepted in the construction industry. “I think construction companies are more reluctant for many reasons, like investment level, and the difficulties with the power supply,” said Liu. ”It is a challenge for us, but we are not giving up. We now that the benefits are high for contractors. We see a lot of potential for demolition robots in the future in China.”

In China there are thousands of small construction companies and around 100 big ones. In terms of concrete cutting contractors around 10 really big and several hundreds one to two man companies. It appears the same with demolition contractors. But things develop extremely fast in China. Soon many of the contractors that are small today will be medium size and demand more efficient equipment. But it is difficult to estimate the size of the market, as there are no branch associations for concrete cutters or demolition contractors.

“China is truly an amazing country that evolves with the speed of light. I am really fortunate to see it change and experience it at close range,” said Segers.

A maturing industry’s potential Grinding and polishing of concrete floors is progressively becoming a mature industry, but its potential has so far only scratched the surface. It is mainly in the US and parts of Europe and Australia were the method has had a serious impact so far. PDi reports.

20 PDi • Issue 5 • 2013

But the method’s distribution becomes increasingly evident in other parts of the world as the foremost major manufacturers in the area are expanding market shares with increased sales, subsidiaries and independent distributors. This has led to new users, but also new manufacturers of equipment and diamond tools. The first wave of interest came a few years ago in the form of many Asian manufacturers that started producing cheaper machinery and equipment. Many cases concerned the copying of already existing products. The quality was variable and often the availability of service and spare parts was limited or unavailable. As always, the industry discovered this fairly quickly and the number of new entrants. Today the market has become more consolidated and stable.

Increasing popularity Further, the method to grind and polish concrete floors into a finished end product is most widespread in the US. In the US, the method is also widely used in the construction of new concrete floors. It is also common that the new concrete floor is stained or marbled differently, causing the concrete to resemble a stone floor. Concrete floors need polishing for up to ten stages and the finished surface is easy to maintain and clean without harmful chemicals and has a life of up to 15 to 20 years. If polished concrete floors are incorporated in new projects the amount and distribution of aggregates in the concrete can be assessed.

There is also the option to choose what type of aggregate to use to create the most aesthetic concrete as possible.

That said, the US has the largest market but also Australia and parts of Europe are quite substantial. The method is originally from Sweden and developed by HTC Sweden. Grinding

and levelling of existing concrete floors is common in Sweden, but to go all the way and polish up the concrete floor to super finish is still not widespread, although it is on the increase. The countries of continental Europe, and especially Germany polish concrete floors to a greater extent and the potential is great.

In markets in Asia, South America, the Middle East and parts of Africa the method is also increasing in popularity.

Treatment of concrete floors requires the right equipment and tools, it requires an efficient method of polishing concrete and facilities for demonstrations and training is crucial. In markets with low purchasing power it may be more difficult to sell the concept or the need to create different types of financing before it is accepted.

Currently there is no shortage of manufacturers of machines for grinding and polishing concrete floors. There are a large number of manufacturers, but the quality varies. The same applies for the tools. But the number of distinct methods for grinding concrete to super finish in up to 10 steps is limited.

Only a handful of companies offer and market their practices on a global level.

Great potential in China and Brazil Examples of new markets, where the grinding and polishing of concrete floors starting to get a stronger foothold in addition to the traditional markets, are China and Brazil. Both countries are undergoing a significant transformation, with a plethora of new projects scheduled. For Brazil, of course, an important engine is the fact that the country’s economy has strengthened in recent years, but also because the country is will stage the football World Cup in 2014 and the Olympics in 2016.

Aggressive tools at aggressive prices HTC’s new Greyline Superprep diamond tools are aggressive in many ways. Developed with matrix technology HTC has created aggressive tools at aggressive prices.

The new series have three different tools where the GL Superprep 0 is available in two different versions, one for hard concrete and one for soft concrete. The two coarsest steps in the GL Superprep series contain a mix of crushed PCD and diamonds to give a high cut rate. The tools are good for various floor preparation tasks, including removal of coatings, asbestos, glue or any other residue.

coast and around the big cities, there are extensive renovations and new facilities being built. In China, this change has already been going on for the last decade. Both countries are accepting for floor grinding and polishing because the method is much more environmentally friendly than other types of flooring treatments. In particular, China’s government supports practices that lower the negative impact on the environment. China is seeking to reduce the use of stone and terrazzo floors. Increase of polished concrete flooring also reduces the use of epoxy floors.

In China, there are currently a number of manufacturers of machines for grinding and polishing. In Brazil, it is hard to decide who dominates the market as international manufacturer are becoming common. There is only one Brazilian manufacturer of floor grinding machines LVS in the city of Curitiba in the south of Brazil. According to the manufacturer their machines have been used for grinding and polishing 1.5Mm2 in Brazil and they have about 50% of he market.

Training and demonstrations The lack of training and demonstrations is holding back the development of concrete floor grinding and polishing. In northern Europe, where the method was born, demolition and concrete cutting contractors started to use concrete floor grinding machines on their projects to removing adhesive residue and other types of floor coverings. Contractors found it easy to offer these services. The trend has now spread to all of Europe. Industry associations in concrete cutting and demolition have started to organise training and certification for their members. In recent years, the US Concrete Sawing and Drilling Association invested

in training and certification courses for its members. The same goes for Australia. But when it comes to the choice of polished concrete floors during the construction of new buildings, it is more specialized flooring companies that embraced the method.

Recent changes There have been some recent changes in the industry. HTC Sweden was acquired by Polaris Private Equity, a leading Danish and Swedish venture capital firm focusing on investments in medium sized companies based in Sweden and Denmark. The former owner and founding family Thysell is no longer active in the company. HTC is still the market leader and has a strong presence, particularly in Europe and the US. Another strong player, especially on the US market is Superabrasive with the product line Lavina. Headquarters are in Hoschton in the state of Georgia, but the company has its own manufacturing plant in Krun in Bulgaria. It also has a large warehouse in Atlanta for the American market and a recently opened sales office in Ukraine. Superabrasive is strong in the US market and has not invested so heavily in Europe until recently.

Also Husqvarna Construction Products is focusing on Hiperfloor, its own system for polishing concrete floors in China.

One of HCP’s partners in China believes there is enormous potential in the country for grinding and polishing concrete floors. In addition Scanmaskin has set up its own US subsidiary and has a new co-operation with the US company JonDon, a specialist in equipment for treatment of floors.

On the following pages PDi reports on concrete floor grinding and polishing around the globe.

First grinding machine with DCS System

The Italian company Klindex has introduced the Hercules DCS System that has the features of two separate machines. Using the Hercules in counter rotating mode it is a grinding and polishing machine for concrete, marble and natural stone floors. However, the machine in DCS System mode the speed of the satellites is increased turning the Hercules in to a high performance industrial floor preparation machine. This makes it suitable for fast removal of resins and glues, exposing aggregates and for levelling of very uneven surfaces. The main features include its ability, with a working width of 800mm, to run with four 240mm tools that range in speed from 450 to 1,300revs/min. It also has a gearbox with thermo-hardened steel gears, and an auto levelling planetary system.

Klindex Superconcrete HS The Italian manufacturer of concrete floor grinding equipment, Klindex, also promote their own concrete polishing system called Superconcrete HS. According to Klindex they have the quickest and easiest way to transform any trowelled concrete surface into an aesthetically pleasing, durable and stain resistant one that looks like a mirror and strong like iron. The solution is the technology of the new King Conc diamond

22 PDi • Issue 5 • 2013

impregnated floor pads, to achieve a glossy concrete floor.

There are many benefits of using Superconcrete HS. These include increasing the strength of the concrete floor, helping control dust, scratch, stain and wear resistant, water repellent, extremely economical for commercial and industrial areas, low maintenance, environmentally friendly, green flooring choice V.O.C FREE, allowing the

floor to breath in order to prevent spalling and extremely long lasting when compared to original methods like resin floors.

Shopping for a super polish Retail stores on the hunt for a superior floor finish, are regularly turning to Pro Grind Australia to deliver a hard wearing, stain resistant and aesthetically pleasing mechanically polished concrete finish. High foot traffic, floor staining, pallet manoeuvring and refitting of stores, can add years to the life of a traditional floor covering, such as vinyl or epoxy. This results in high maintenance costs for the retail environment.

Pro Grind Australia is at the forefront of both product and productivity solutions for large retailers with the capacity to deliver over 50,000m2

Superabrasive’s new machines In Bulgaria Superabrasive has added three models to their Lavina series, each featuring new technology. The new remotely controlled Lavina 32R-S-E is the first of its kind in the Lavina line, and the first remotely controlled grinder/polisher to feature gyroscopic technology. This allows the machine to maintain a straight grinding/polishing path by ignoring uneven floors and disturbances of up to 30°. Lavina 32R-S-E is operated by a wireless, easy grip remote control, and works hands free up to 100m from the remote. A system of continuous checks between the machine and the remote, in addition to several safety features, ensures the 32R-S-E is always on its correct path and operating as intended.

In addition, the new Lavina 25M-S-E offers selfpropelled movement, also new to Lavina. A second motor propels the machine forward, requiring little effort from the operator. This model is also available in a 11,5 kW Lavina 25LM-S-E version.

Superabrasive has also introduced the Lavina 13-S-E edger, with several new features designed to blend edge work and eliminate unsightly lines. A new gauge which allows the operator to control the angle of the head up to 4° in each direction, a new

nationally, offering retailers consistent finishes with guarantees for enduring floor performance.

Retailers have been quick to acknowledge the benefits of an extremely hard wearing, resilient, aesthetically complimentary and low life cycle cost flooring solution.

“One of the hazards of being in our industry is staining on the floor and this can badly affect the look and feel of a store, as well as increasing the time and money spent on trying to keep the floor clean,” said a representative from national wine retailer Dan Muphy. “We knew that polished concrete was the solution and Pro Grind provided us with the added reassurance of the quality and consistency of their product for our brand which

level which checks the flatness of the floor, and the addition of a forward/reverse option are some of the new features. The 335mm edger is offered in two models – 13-S-E with a 2.2kW motor and 13N-S-E with a 4kW motor. Other new products include the new Lavina vacuum line, new QuickChange metal tools with rectangular segments, and ShinePro, Superabrasive’s new line of diamond impregnated pads for floor maintenance. There are more new machines and tools in the pipeline and will launched at the forthcoming World of Concrete show on stands S12027 and O30842.

Single surface flooring solutions As architects and designers look to expressive, individually designed retail spaces, floor-covering boundaries are being pushed. Pro Grind Australia considers to what extent this is impacting on individual store maintenance, flooring longevity and lifecycle costing.

The new ArtHouse in Portland, Oregon, opened in September. The ground floor level has floors with the Hiperfloor solution.

Making the world greener with Hiperfloor

Multiple floor coverings require different maintenance methods Flooring choices are enormous with many stores adopting a multiple overlaying approach.

This method gives designers scope to create a zoning feel and personalise the flooring area in accordance with the product on display.

Multi-surface floor coverings create a variety of complications for storeowners and in particular their maintenance crews. Multiple floor coverings require different maintenance methods. Wear and tear is different across the coverings often affecting the lifespan of the product leading to different replacement requirements and timeframes. This directly impacts the lifecycle costing of the floor.

Applying different overlays may lead to height differences between the surfaces creating trip hazards and potentially different trades required to install the floors. Although the multi surface overlaying approach is frequently used to create different zones and ambience in stores, it can impact the feel of the size negatively and create an inconsistent feel to the spaces.

The growing application of Pro Grind’s MPC polished concrete in retail spaces is an example of a product approach looking to overcome the disadvantages of multiple overlays. Directly impacting the aesthetic of each individual floor, ProGrind’s MPC provides flat, consistent, durable and easily maintainable single surface flooring solutions. There is no requirement for different cleaning regimes, an autoscrubber or mop is all that is required. The lifecycle cost of MPC flooring is significantly lower than the multiple coverings

approach and due to its resilience and durability it does not scratch or fade as it is not a coating or a covering.

The whole stor floor in polished concrete Added benefits include the environmental benefits of it’s full Green Star credit rating as well as eliminating landfill additions as the substrate of the floor is used as the total product rather than an overlay, which will later will be removed and disposed of. The polished concrete surface compliments individual stores with a fresh, bright and consistent feel, increasing the sensation of light and space. Zoning effects if desired can be achieved through clever lighting and product placement techniques.

Customers such as Early Settler and Beacon lighting have benefited significantly from making the shift from multi surface floor coverings to Pro Grind’s MPC solutions. “We only used to do the walkways in the stores, but now with the Pro Grind MPC, we are doing the whole stores and they look incredible. The new Pro Grind floors are easier to clean, don’t scratch as easily and make the stores look fantastic. We have received heaps of positive feedback from customers about the new flooring, with customers even asking where they can get a quote for their home or business,” said Beacon Lighting national facilities manager Bryan Findlay.

Christopher Bennett said that Husqvarna’s Hiperfloor solution is the perfect fit for this kind of project. “It is a very clean and long-lasting floor, and it’s also beautiful, which is important in retail spaces. But the most important aspect is that every time we make a Hiperfloor we are making the world just a little bit cleaner. A Hiperfloor uses less chemicals and materials and it keeps the energy bills down, because the warm, very natural reflectiveness of the floor reduces the need for overhead lighting,” said Bennett.

Fast growth for Scanmaskin in the US The Swedish manufacturer Scanmaskin saw its activities expand last year, particularly in the US.

Scanmaskin set up its own US subsidiary in Bellevue, Washington at the end of 2012 under the guidance of US manager Josh Headings. “Over the past six months we’ve been growing very quickly and it’s due to a number of things,” said Headings.

Building up a network

With the addition of the Scanmaskin product line, they are now launching a marketing campaign to promote Scanmaskin products all over the US as they expand their concrete division. Their goal is to eventually dominate the US market in this particular industry. “We are very excited to be working with a company like Jon-Don and we hope to double our turnover in the US by next year,” said Headings. “Jon- Don is a quality company that has a great reputation among customers and vendors alike.

Their three core business principles are to build good relationships with customers, employees and vendors/suppliers.”

Soon after the last World of Concrete Quest Building Products show Headings began corresponding Quest Building Products is the Scanwith Jon-Don, a large flooring equipmaskin distributor for Southern Caliment distributors based in Chicago, fornia, Las Vegas, and Phoenix, and Illinois.

Jon Don invests in concrete flooring

Jon-Don was founded in 1978 by Nick Paolella, along with his cousin John. The company has expanded since then and has now a total of 11 stores from the US west to the east coast. Up until about two years ago, Jon-Don’s primary business was janitorial and maintenance products, such as carpet cleaning and natural stone maintenance.

However, two years ago Jon-Don purchased a smaller company, Ryno Tools and Supply, which was owned by two brothers and specialized in the decorative concrete and concrete restoration industry. After the acquisition of Ryno, Jon-Don started working on developing their concrete division, focusing on concrete restoration, decorative concrete, and floor coatings.

Quest also has weekly training classes taught by industry professionals covering a wide variety of topics and trades.

Majik Diamond Supply In Northern California, Scanmaskin products are distributed by Majik Diamond Supply. Majik specialises in providing solutions to the decorative concrete and surface preparation industry. With a strong customer base in Sacramento and the San Francisco Bay area, Majik prides itself on being a 24 hour a day 7 days a week company.

The company is built around a philosophy that as long as their customers are working, Majik will be there to provide them with the tools needed to get the job done. Majik is also distributor of many well known brands including Ermator, Metzger/McGuire, CT RapidSet, WR Meadows and Prosoco.

“Scanmaskin USA has a lot going on right now and we look forward to a great second year of business in the US. The WOC show in January will also be great for Scanmaskin, and the level of customer awareness should be much better than last year. The US market is definitely one of the most exciting and dynamic to work with, and this is just the beginning,” said Headings.

Neat and shiny at Thai Summit.

Thai Summit, a satisfied client Thai Summit is an auto parts manufacturer near Detroit, Michigan and has been using Scanmaskin equipment for about six months. Thai has close to 93,000m2 of concrete floors in their facility that they are grinding and polishing.

Thai owns a Scanmaskin SC1000, SC800, SC650, and SC330 floor grinder and like the results they are getting.

The primary reason for Thai deciding to polish their floors is because they are easy to clean, along with the improvement in appearance and workplace environment. Thai has recently built another building in order to expand their productivity and they are grinding and polishing the floor from the start. “It’s great to see how large corporations want to improve their facilities by polishing their floors and that they are using our machines and system to do it,” said Headings.

Scanmaskin expands worldwide But it is not only in the US things have happened for Scanmaskin, which has its head office outside Gothenburg, Sweden. Founder and managing director Claes-Goran Bergstrand said that Scanmaskin has been expanding their market not just in the US. “Over the past few months, in addition to significant growth in the US, Scanmaskin has recently expanded into the UK and Austria. Currently the UK and Austria are served by authorised distributors, offering the entire line of Scanmaskin products.

Scanmaskin is now in the process of setting up distribution in South America, along with further development and expansion in North America. “We believe there is a great potential in South America for our products and we are actively looking for distributors,” said Headings.

“We are very pleased with the growth in the US over the past year and are looking forward to future growth in 2014,” said Scanmaskin sales and marketing manager Paulo Bergstrand. “Scanmaskin has become a global player with a network of distributors and offices spread across five continents. We are also looking forward to a great show next year at the World of Concrete, and anticipate steady growth in years to come.”

Doing more with less Brazil’s largest domestic manufacturer of concrete floor grinding and polishing machines is set to grow domestically and internationally. But yet they have to take care of the booming Brazilian construction industry.

Luiz Carlos Beraldo reports.

LVS is one of few manufacturers of concrete floor grinding and polishing machines in South America and is based on the outskirts of the Brazilian city of Curitiba. “A year ago this premises was a home, a residential building where we used to assemble our machines and take care of all the administrative work,” said LVS finance director Alzira da Silva. “Then we decided to take on the task of renovating the company’s facilities to create a pleasant and larger workplace, more suitable to receive customers from all over Brazil and, more recently, other countries, who want to visit and get to know us and our products better. And, of course, we also needed a larger area for assembling machines.”

Started in 1999 Alzira’s husband and company president, Luiz Carlos da Silva, started the business in 1999. He is currently focused on customer service and development of product and production. The company currently produces the LVS Luiz Carlos da Silva, President of LVS, in front of the LVS premices in Curitiba, Brazil.

5.5, LVS 7.0, and LVS 8.5, plus parts and accessories used for different types of cutting, sanding, and polishing. The machines are assembled in-house, with parts produced by local suppliers based on Luiz Carlos da Silva’s international patent obtained in 1999.

“Our story has two stages,” said Luiz Carlos da Silva.

“First there was the development phase, assembly of units for testing and then delivery of the first units in 1999.

But LVS was founded in 2007, with series production and a portfolio of clients interested in the new product.”

Since then, the business has progressed year after year, and the company has increased its market share, which until now was dominated by imported equipment. The company has so far produced and delivered close to 600 machines. “We have grown gradually, and in recent years with more impact,” said Alzira da Silva. “In 2012 we had a weak first half year, but in the second half sales took off and we started in 2013 with many orders. This year has started much better than last year.”

Attending to the demands of the market Before opening his own business, Luiz Carlos da Silva worked at a major manufacturer of construction products, and had constant contact with contractors operating in this sector. Thus, he sought to develop a device that could bring solutions to attend the demand of the market, aspirations that he personally identified with the users of the machines.

“First I realized I could make a product with a much lower price than the imported ones,” said Silva. “Then, I could develop my own product. I started to wonder why the machines produced by my biggest competitor had such a higher price. Soon I understood there were reasons for this, details that made all the difference in quality, productivity, durability, and economy.”

Ultimately, Luiz Carlos da Silva developed product improvements that competitors did not have. “Today, if you ask a construction company or contractor using my equipment and also the one provided by another brand, he will tell you that my product is far superior,” said Silva.

Luiz Carlos da Silva said that in all the details, he sought solutions for problems found day-to-day by the users of the machines, such as design improvements with better ergonomics to minimize transfer of vibrations to the operator. “A worker who works eight hours with our equipment ends the day feeling better than he would feel using another brand,” said Silva.

LVS concrete floor grinding and polishing machines are on average larger diameter than the existing ones on the market. “They are easier to handle, easier to transport as they can be dismantled in

parts,” said Silva. “They work on voltage 220/380 VAC, three phase, or 440 VCA custom. We typically offer machines with a frequency inverter speed control and thermal protection.”

Changing the planetary disc on LVS grinders is also easy thanks to a unique system that uses no screws. The large planetary disc is designed so the diamond tool is easy to fit in a crib with tapered bevel. To install a grinding or polishing disc, just needs pressing it from inside to outside. The centrifugal force of the rotating disk causes it to be constantly pressed on the bevel angle plug, keeping it firmly fixed in the crib and eliminating the use of screws or latches. Just a slight tap with a hammer on the back of the piece is all that is necessary to remove it. “It is much more practical because during operation or change, the equipment may contain clay or mud on the disc, which makes the use of keys difficult,” said Silva.

Another point of pride is productivity. The LVS 85 polisher, with a diameter of 850mm is a planetary-geared machine and does not leave ripples on the surface. “But it’s not just the diameter that makes it more productive,” said Silva. “I also offer the best domestic and imported grinding and polishing tools to my customers. The tools are tested in our own test track where we test the machines on many different types of materials, such as granite, marble, concrete, and tile.”

LVS work with tool suppliers to get the highest quality materials that will provide the ideal

Alzira Aparecida da Silva, in charge of finances at LVS and wife to Luiz Carlos. hardness and sanding ability to give the best result. “The technology is constantly improving,” said Silva. “I keep myself updated and apply the news in my product.”

Customer training Another difference that sets LVS apart, says Alzira, is the training and after-sales service. “We do not deliver and say make good use of this and be happy,’” said Alzira da Silva. “We offer training for customers or operators to use machines in order to get the best result. Our

technical assistance is from our own factory. When clients need assistance, we send technicians with the genuine spare parts.”

When creating the factory for concrete floor grinding and polishing machines, Luiz Carlos da Silva thought to meet initially the Brazilian market. “But given the high quality of our products we are exporting to other countries, such as Argentina, Portugal, Paraguay, and Mozambique,” said Silva. “For added versatility, the products are designed to be adapted for use with any kind of steel tool and resin-coated tool.”

In the Brazilian market, LVS’s more expensive machine is sold for R$30,000.00, about 20% less than the comparable imported models. “We compete with imports,” said Silva, adding that there are no official figures on volumes in this segment, but estimates that the LVS market share in Brazil is more than 50%. The concrete grinding and polishing market in Brazil is booming.

“We are in a time of growth in civil construction in Brazil, with major projects such as stadiums and other infrastructure projects around the country,” said Silva.

“This is moving the market forward. We have a customer who is doing polished concrete floor work at the airport and another one polishing halls at one stadium being prepared for the 2014 World Cup. There are also large numbers of floors being polished in shopping centres,

Brilliant floors – we‘ll give your floor the perfect finish!

among others,” said Silva.

The future In 2012 LVS sold 120 units, half of which were the larger capacity LVS 8.5. The intermediate LVS 7.0 accounted for 35% of sales, and the LVS 5.5 at 15%.

“In 2013 we expect a growth of 20%t in the domestic market, with exports holding steady at 15% to 20% of our business,” said Silva. “In addition to our current markets, I’m hopeful we can soon export to the United States and Europe.”

The company occupies a building area of approximately 400m2 and has 10 employees and the Silva’s son Vinicius also works at the company as industrial director.

Their daughter Rafaela, is studying civil engineering at University, but also works mainly with purchase of components and inputs.

The current facilities can produce up to 300 units/ year, more than double what LVS currently sells working on one shift. “But we can operate in two or even three shifts if there is need,” said Silva. “Yes we can grow; we just need the orders.”

LVS is already planning to introduce a new machine with a diameter of 1.2m for even greater productivity.

“We are already in advanced stages of development and, if all goes well, we will begin marketing it soon and by 2014 at the latest,” said Silva. “We are also expecting the launch of a machine for polishing work.”

Before the Chinese painting company owner Sun GuoSheng met Husqvarna Construction Products in 2012 he did not know that it was possible to polish concrete floors to a premium finish. Now he is convinced Husqvarna HiPERFLOOR® method for grinding and polishing concrete floors, is the right method for China.

Sun has prepared a giant showroom where he can demonstrate both how the method works and how the final product looks.

Sun from the Chinese flooring company HeFuLe, concrete floor grinding system, has absorbed the new trend. He is determined to conquer the Chinese concrete floor grinding and polishing market and implement the HiPERFLOOR method all over the country.

Billions of concrete floors to polish China has a huge number of old concrete floors that need to be renovated and new ones that need to be polished just in the Shanghai area. So that is where Sun decided to start his business.

Sun is dedicated to grinding and polishing and to the HiPERFLOOR method in particular. When he was introduced to HiPERFLOOR method a couple of years ago he was hooked and saw great potential for the technique.

At the beginning of this year Sun purchased seven Husqvarna PG 820 floor grinders and a number of Husqvarna DC 5500 from Husqvarna Construction dust collectors. In the spring he opened a service centre in the suburb of Shanghai measuring 2000 m2 of demonstration area, workshop, offices and storage.

Concrete floor grinding and polishing is not a new method.

In China though it is still very new and unknown to many and this is where Sun sees great potential. “China is just at the beginning to adapt to this new method and we have a lot to go. My company is one of the first to embrace it professionally and offer these services on a broad scale,” said Sun. The biggest potential is polishing of new concrete floors.

Construction of new apartments, shopping centres and offices is taking place all over the country. Also there are many infrastructure projects ongoing. Being a concrete flooring company that has a new Sun and his staff is right now taking on a large grinding and polishing job in the outskirts of Shanghai.

flooring method to offer that is quick to install, environmentally friendly, sustainable and easy to maintain has all to win and nothing to loose. There are billions of square meters of concrete floors being produced. The advantages of concrete floor polishing are considerable and is not threatened by alternative methods with low price labour. However, it might be difficult to convince architects that this is best method to use.

Husqvarna Construction sales and marketing director for China Lawrence Liu, said that the Chinese government encourage alternative methods like concrete floor polishing that strives to lower the negative effects on the environment. Using natural stone floors is considered a negative impact on the nature.

Sun and his team is very important to us to implement the HiPERFLOOR method in China and I am very optimistic about our co-operation, said Liu. Since we started early in 2013 we have mainly been investing in doing a lot of demonstrations showing how this method works and how our clients can benefit from it.

Both Sun and Liu said that the showroom in Shanghai is very important for selling the idea of the HiPERFLOOR method. The showroom has a huge concrete floor polished using the HiPERFLOOR method. In different areas of the floor Sun has arranged different levels of polished concrete. This is where we bring our existing and potential clients to show what the HiPERFLOOR method can give. Here we also do our training. We also attend China Floor exhibitions together with Husqvarna to demonstrate HiPERFLOOR, said Sun. In less than a year the company has grown to 12 employees and work is carried all over China, but so far mainly in the Shanghai area. The work to sell the HiPERFLOOR concept has taken

time but now Sun is starting to see that his efforts are paying off.

Clients have started to order his services and currently have two large grinding and polishing projects near Shanghai. They have also closed a deal with a building and construction company for polishing concrete in many of their new projects.

20,000m2 polished floor One ongoing project is the renovation of a plant that will be transformed into a factory for manufacturing machine parts.

All floors will be levelled and polished. On all walking areas the polished concrete will have the highest grit level, while areas with machines on will have lower grit. About 20,000m2 will be polished in three different buildings divided in two floors. This is a perfect job for us and it has easy access. There are thousands of similar projects just around Shanghai where the HiPERFLOOR method would be the best solution. When this job is done it will be a perfect reference job for us, said Sun. The current machine fleet from Husqvarna is sufficient, but if business develops at the same rates as in the previous months Sun is going to need more machines and staff. Chemicals and diamond tools are delivered continuously for use on the different projects.

Sun and his colleagues have started to look into offering colour the concrete floor. It is similar to that which is commonly used in the US, but not sure if it will be a big success in China.

Sun also wants to be involved at an early stage of new flooring projects to help his clients choose the right type and design of the composition of the aggregate in the concrete.

I have also been working in the painting business for many years and still am. We both do the painting as well as selling paint.

We also still paint a lot of concrete floors, said Sun. that is why I saw the potential in grinding and polishing the concrete floor instead of painting it. Making epoxy floors is time consuming, needs a lot of maintenance, gets extensive in the long run and is not environmentally friendly.

IACDS make or break The International Association of Concrete Drillers and Sawers, was exposed to serious criticism at the association’s last annual meeting in Munich in April. The reason was the lack of results from the association.

Austria, decided to leave IACDS, and Germany proposed an additional meeting to discuss the future of IACDS. The meeting was held in Amsterdam in September. PDi reports.

At the last annual meeting of IACDS, the association received some constructive criticism concerning the lack of results from its activities that the member associations could benefit from. The topic was widely discussed, but it was decided that a special meeting should be held in the autumn to discuss the direction of the association and how it should be working in the future. In particular Lars Sandström. representatives from the concrete cutting member associations around the globe were asked to attend the round table meeting.

Six member associations participated Fifteen delegates attended the meeting at Schiphol airport in Amsterdam. These were the president of the Swedish association Anders Andersson and IACDS president Lars Sandström, IACDS secretary Daniel Trachsel, the president of the Russian association Andrey Kossolapov and the Russian delegate Evgeny Shke- Daniel Trachsel. dov, president and secretary of the German association Thomas Springer and Hans-George Wagner, Philippe Wingeier, the new president from the Swiss association, from the UK association Julie White, Pedro Villuela and Jose Blanco from the Spanish association, Alfred Landl from the Austrian manufacturer Tyrolit, and PDi editor Jan Hermansson. Those that did not participate were the USA, Australia, Japan and France.

What do we want from IACDS? IACDS president Lars Sandström opened the meeting and spoke about the importance of the concrete sawing and drilling industry. Sandström emphasised the importance of more representatives from the member associations attending the IACDS meetings. IACDS secretary Daniel Trachsel then continued with a resume of the annual meeting in April.

President of the German association Thomas Spring-

er, who initiated the meeting in Amsterdam, repeated the purpose of the meeting. “We need to ask ourselves what we want from IACDS. Until now we have seen too much lobbying, too few contractors and maybe too many suppliers. We have created too many letters of intent and have seen so far very little action,” said Springer. He also added that the German association has no intention to leave IACDS and intends to find a way to fill IACDS with life and that the umbrella associations start to produce something that the whole industry can benefit from.

One reason why very little has come out of IACDS is the lack of time and money. With the IACDS budget and one meeting a year it is hard to expect that so much can be done.

After the delegates had the opportunity to express their views, the IACDS bylaws where presented, stating the responsibility and ambition IACDS should have.

IACDS has a purpose The meeting soon came to an understanding that there were many things that IACDS could work with to improve the situation for the industry. Philippe Wingeier from the Swiss association did stick out among the other participants and was frank with his comments. Wingeier said that the board of the Swiss association has no information regarding IACDS, which he said was in part an internal problem of the Swiss association, but considered IACDS was a coffee drinking circle. “That’s okay with us. The Diamond Award is okay also. International norms are impossible for us to follow and cannot be applied in Switzerland,” said Wingeier. “We define IACDS as a networking platform for exchange of information. We couldn’t even find a common training scheme between Switzerland, Germany and France.

The international tolerances can’t be used in Switzerland. They are okay for amateurs, not for professionals.

I represent 100 members, most of them having two to five 5 employees.

They are not interested in Russian rules. This is the opinion of the board of the Swiss Association.”

Other delegates confirmed that it is hard to create common work practices in some areas, such as tolerances.

But there are several other areas where the industry could improve by having an efficient networking between countries. IACDS should, therefore, be the best way of doing this, as it already exists. Anders Andersson, president of the Swedish association said that maybe it would be easier to have a European association instead and that such an association would create more useful output.

Thomas Springer gave an example where the German speaking countries and the Netherlands have co-operated in a sort of continental Europe group. Switzerland left the group after a while, but a tangible result came out of the work. It developed a separating and fixing system for core drills, which makes it possible to shift core bits by hand without a tool. “This shows that this

informal group brought up useful and beneficial results.

The German construction federation VDMA took over the development and the new system will be launched at the German show Bebosa next year. A coffee drinking club is okay, but not enough. We have clearly the instruments to create something more and many tasks to work with,” said Springer.

Brainstorming on important topics This brought the meeting to a new and creative stage and resulted in discussions about creating a number of working groups within IACDS. “What we need in the UK that IACDS should do is to work out best practice Issue 5 • 2013 •

rules in many sectors of concrete cutters’ work and we need quick results. I think this is the best way to justify the existence of IACDS,” said Julie White from the UK association.

“I agree fully. We need to create working groups for important issues. And there are many important issues to deal with,” said Andrey Kossolapov from the Russian association.

“I want to ask what are the fields of activities in which IACDS can and should become active and create working groups,” said IACDS president Lars Sandström.

“I see three useful tasks for IACDS, which are training, health and safety and technical issues,” said Jan Hermansson from PDi Magazine.

the issue by saying that depending on an individual situation, you have to concentrate on one of the lines in a triangle, representing goals, resources and teams.

What are the subjects we have always talked about and continue to talk about today? It’s the same issues relevant for any other industry: education/training, health/ safety, environment, technology and development, statistics and communication/marketing. Now we have to decide whether and how we want to bring the subjects into the triangle. “As a president I had the goals of communication, updated website and effective PR communication for DA and Bauma seminar. We have to define clear and makeable goals today. Not tomorrow, but today,” said Blanco.

The afternoon was used for brainstorming over what issues were most important for IACDS to work with in working groups in the future. Many proposals were brought to the table, some were rejected and Daniel Trachsel summarised a list of proposals for discussions next summer.

Presentations in Madrid, June 2014 The meeting decided to prepare a detailed document of what was decided at the meeting in Amsterdam including the list of tasks. The document will be sent out to all delegates of IACDS. Thomas Springer proposed that each national association should take over one specific subject from the list of topics to prepare and to present next year at the IACDS annual meeting in Madrid. This was the core idea of a new procedure to bring activities into IACDS:

Switzerland Germany Germany Germany Spain Spain Russia Russia Russia Russia Sweden Sweden SE / United Kingdom United Kingdom Secretary USA To be assigned later To be assigned later To be assigned later To be assigned later

the responsibility for a subject goes from individuals to national associations.

All delegates agreed to his proposal and the associations took over the responsibility of the topics listed. USA was not present at the meeting and would be contacted about their tasks and if they would agree to their responsibilities.

The final presentation of each topic will be presented at the meeting in Madrid in 2014. But first a draft document in English should be prepared and be delivered at the latest at the beginning of the BeBoSa show in Germany in March describing the problem, and possibilities of solving them. It should keep an international level by including input of other national associations but normally developed in a second phase.

It was decided that all involved should do their job as best as possible, mainly starting with their own experience. The international aspect will come in a second phase. “We shouldn’t expect too much in a first phase. But this is very good start to bring IACDS’ mission forward to enable the association to actually can deliver something beneficial to its members,” said Springer. It was decided that all documents should have a uniform layout.

Delegates seemed satisfied with what had been decided at the meeting and that IACDS’ purposes actually had been clarified. Most of the participants believed that this was a breakthrough for making IACDS a more useful international association.

Industry first sets standard for surface texture In the US the concrete polishing and surface preparation industry now has vital new resources, including a first of its kind, to measure job success, thanks to the Concrete Sawing and Drilling Association. In response to requests by architects and engineers to resolve consistency issues associated with quality levels achieved by polished concrete surfaces, the CSDA has released two technical documents, an industry Standard and a Best Practice.

CSDA Standard ST-115 Measuring Concrete Micro Surface Texture is a collaborative effort between the CSDA Polishing and Standards and Specifications Committees. It identifies approved instrumentation for measuring surface texture and

38 PDi • Issue 5 • 2013

provides a benchmark measurement procedure for contractors and specifiers to follow. The document covers important steps in the production of a quality floor system and gives useful guidelines associated with the testing and inspection of a finished concrete surface. In addition CSDA-ST-115 includes a standard process for documenting surface texture readings, a list of industry terms and definitions and a section on codes, symbols and charts to assist concrete polishers.

“The release of this Standard could not have come at a better time,” said, CSDA polishing committee chairman Andy Bowman. “Some see the polishing industry as an unorganised group in need of consistent language, definitions and

universal criteria. Now, CSDA has created a document with defining vocabulary that provides a consistent message throughout the industry. The challenge was to take artistic minded techniques and adapt them to a more scientific approach. I feel we have achieved that.”

The accompanying Best Practice, CSDABP-015 Green Polishing and Grinding Practices, has been devised to help concrete polishing and grinding contractors create a detailed plan for performing their work in a more environmentally-friendly manner. It provides guidelines and recommendations for companies to employ on sites, in the office

or in the shop.

“These new documents are the culmination of hard work and dedication shown by members of CSDA’s Polishing Committee. The result is two robust industry documents that polishing contractors can refer to on any job,” said CSDA executive director Patrick O’Brien.

“One provides the industry with finite rules for measuring the surface texture of a concrete floor system, as well as giving set parameters to create high-quality polished concrete floors with consistency. The other informs and educates polishing businesses about green practices, a constant hot topic within the concrete industry.”

A big shot in surf Blastrac is a major force in shot blasting and surface preparation equipment. For over a hundred years the company has built a reputation as innovators in surface preparation.

Andrei Bushmarin reports.

The technique of abrasive blasting may have different variations, such as bead, sand or shot blasting, but the main principle remains the same. Pressurized air or a centrifugal wheel propels the material against a surface to be roughened, smoothed, shaped or cleaned. The method was first patented in 1870 by Benjamin Chew Tilghman, an American army officer, inventor and entrepreneur. It was natural that the US became the cradle of the blasting industry and it was in North America that Blastrac originated over a century ago.

The rule of wheel The parent firm Blastrac would later grow out of the original operation founded in Pittsburgh, Pennsylvania in 1908 under the name of Homogeneous Sand Mixing Machine Company. As it supplied equipment for foundries, it was soon rebranded to American Foundry Equipment Company. Until the early 1930s its development was relatively unspectacular. But in 1932, Louis Peik, a company engineer, patented his first blasting machine called Tumblast.

Hot on its heels was the Wheelabrator, a groundbreaking innovation in stationary shot blasting, which was debuted at the Chicago world trade fair in 1933.

The machine’s key element was a centrifugal force blast

wheel, hence the name Wheelabrator. The invention proved so popular that by 1943, a mere 10 years after its launch, over 2,000 units were running all over the world. The company acknowledged the success of the brand by renaming itself again to American Wheelabrator and Equipment.

Blastrac blasts off In the late 1970s, the company began looking into the concept of mobile shot blasting. A special division was formed, which set about developing portable shot blasters. The first machine was delivered in the early 1980s. Shortly after that, the mobile department was spun off of the parent company under the name of Blastrac, with production facilities in the UK. Portable blasters enjoyed instant success, which allowed Blastrac to begin expanding into other markets.

The first European sales and service office was opened in 1982 in Germany. It was followed on by similar organisations in France and Spain. In 2004, production was moved to Nieuwegein, a small town near Utrecht. But just two years later, Blastrac opened a new factory in Poland. Equipped with the latest lasercutting stations, bending presses and welding robots, it became Blastrac’s flagship production unit, where over 80% of parts and components for surface preparation machinery is made. All pre-fabricated parts are shipped to Nieuwegein for quality check and final assembly.

Within the last four years Blastrac has also succeeded in branching out to the Middle East, Ukraine and Italy.

Surface treatment solutions for every application Although shot blasting remains Blastrac’s core business, it builds a comprehensive range of surface preparation machinery, including bespoke models. Being one of the pioneers of the steel blasting technique, a special offshoot of shot blasting, Blastrac designs steel blasters for horizontal and vertical applications. Originally developed for the petrochemical industry, steel blasting allows the cleaning of various steel structures, such as ship hulls, oil platforms, steel tanks and vessels, in a fast and efficient manner. Blastrac’s floor grinding programme ranges from hand-held to walk-behind models.

Single and triple head grinders come complete with the Blastrac patented quick release system. For the removal of road markings and various coatings, Blastrac offers a choice of scarifying and stripping machines. But what really stands out are its large truck-mounted shot blasters. Fitted with different attachments, these machines are capable of treating large areas of road surfaces within very short times, while Blastrac in-house dust collectors ensure that the process of surface preparation is dust-free. A full range of diamond tooling, which the company markets under the brand name Diamag completes Blastrac’s product offering. To educate dealers and end users about surface preparation and to give them practical training in the five main techniques, Blastrac has set up eight training centres in Europe.

face preparation

Blastrac has an innovative surface treatment technique called bush hammering. It is a process, which enables users to achieve a natural cut stone look on concrete surfaces. The bush hammered concrete is usually used as a decorative application on outdoor areas with anti-skid surfaces, like swimming pools, terraces, garden paths or pedestrian areas. This technique is also recommended for every smooth surface to be converted to anti-skid. Multiple small hammers impact the surface, hammering out new angular edges with exposed aggregates. The degree of texture can be varied to give a fine, medium or rough appearance.

Bush hammering is usually a two-man operation, with one worker running the machine and the other one operating the dust collector equipped with a LongoPack. An aesthetic look with exposed aggregates and anti-skid properties were the main reasons why Colley, a France-based contractor, chose bush hammering for two projects in Southern France. One took place at a restaurant in Loriol sur Drôme and involved bush hammering an area of 210m2. A similar job was completed in the City Hall of Rompon. For these projects, Blastrac supplied two grinders BMG-580PRO and BGV-125AV for

edges, along with dust collector BDC-3160 and a 50mm bush hammer. Blastrac machinery was chosen because of its reliability and user-friendliness. Both projects were completed on time and fulfilled all

aesthetic and anti-skid requirements. Colley was extremely satisfied with the productivity of the BMG580Pro and the lifetime of bush hammering tools.

Another smart solution from Pentruder Swedish concrete cutting equipment specialist Pentruder has a new attachment that makes it possible to use the Pentruder MDU drill motor and modular drive unit for the Pentruder MD1 drill system. This means that instead of a hydraulic motor or a high frequency motor the MDU itself can be used as drive together with Pentruder’s four gear gearbox and a spindle unit. The speed sphere will be extremely wide and there is enough effect and torque for small, deep and big holes.

Pentruder has also a back support, which makes the whole system very stable for very big drill bits.

A number of Pentruder customers are already using the system in Norway and Germany with drill bits with a diameter of 1m and 900mm. In

Norway a 70mm column is being used and in Germany the system is in use with the rail.

Pentruder also has a new co-operation in Sweden with the sales and service company SDC, who will maintain, service and repair Pentruder equipment in Stockholm and the Malardalen area.

Atlas Copco breaker turns 50 Atlas Copco Construction Tools in Essen, Germany, is celebrating the 50th anniversary of the introduction of the hydraulic breaker.

An innovative idea that originated in Essen has transformed the construction and mining industries and is now a worldwide standard.

Krupp Berco Bautechnik, acquired by Atlas Copco in 2002, developed the rig-mounted hydraulic breaker and took out a patent in 1963.

The first machine, the HM 400, attracted huge interest at the Hannover fair in 1967 and more than 2,000 units were sold.

The aim was to save time and labour in demolition and mining operations where, at that time, pneumatic tools were widely used, and the new concept was highly successful. It meant that one person operating a rig-mounted hydraulic breaker could do the same amount of work as several operators with pneumatic tools.

This innovation was the start of a major transformation in the construction and mining industries. Hydraulic breakers are in now in general use and dozens of manufacturers around

42 PDi • Issue 5 • 2013

the globe produce machines of this type under a large number of different brands. Tens of thousands of machines are sold around the world each year.

“It is our belief that there is always a better way of doing things,” said Atlas Copco Construction Tools power demolition tools product line manager Gordon Hambach. “That innovative spirit is a vital part of Atlas Copco’s identity, a vital part of our way of conducting business. It is also the driving force, which has made us a leader in our industry. Innovation is the ultimate driver for long-term profitability and growth.”

Dr. Fritsch German manufacturer of machines for production of diamond tools, Dr. Fritsch, is celebrating their 60th anniversary this year and that is something we want to celebrate in PDi. There is probably not one single professional manufacturer of diamond tools that haven’t heard of Dr. Fritsch. Most of them have their production machines. So Happy Anniversary Dr. Fritsch!

Since Dr Fritsch GmbH was founded in 1953 the company has stood for providing the highest quality and processing standards in the development and production of machines for the diamond tool industry. Moreover, the research and development of particularly high-quality sinter metal powders has been part of Dr. Fritsch’s business for decades. Since 2010 the company is also distributing industrial diamonds.

Started with diamond dies Close to all manufacturers of diamond tools around the world has a Dr. Fritsch machine in their production. Many has several and the whole production is based of equipment from Dr Fritsch.

The story of Dr. Fritsch started with the trade of diamond dies. The diamond tool industry had continuously been growing, but the breakthrough in the production of tools came as soon as synthetic diamond was available in larger quantities. Due to the increasing demand, Dr. Fritsch developed the Sintering Press DSP 6 for the production of segments for grinding wheels and saws.

First production in the garage In the early days the machines were developed in a one room apartment and manufactured re s p e c t i v e l y demonstrated in several garages. There was neither a workshop nor a research and development laboratory available. In order to gain new customers, the DSP 6 – which was much smaller than today’s sintering presses – was packed into the runk

of a Mercedes and demonstrated to potential customers on site.

The company’s manager, Mr. Karl Weber, understood from the very beginning that only the close contact with the customers, the knowledge of their needs, a detailed analysis of the market and a comprehensive service can make a business successful. And this philosophy hasn’t changed ever since within Dr. Fritsch.

“Our highly qualified service technicians are at the disposal of our customers worldwide in order to guarantee a smooth running production,” says one of the two managing directors at Dr. Fritsch, Gerhard Weber.

“Our service includes commissioning and maintenance of the machines, spare part supply, extensive assistance and advice, appropriate training and know-how transfer,” he adds.

Dr. Fritsch exhibited its own machines for the first time on a fair in Kiev in 1976. It is worth mentioning that the success of the fair was also due to the fact, that Dr. Fritsch was the only exhibitor who offered the visitors snacks and drinks.

Ever since, the numbers of fairs in which the company are participating has steadily increased. Nowadays Dr. Fritsch present their machines and powders at important national and international fairs like the Marmomacc in Verona, Italy, BAUMA in Munich and the Stone Fair in Xiamen, China to mention a few.

Divided in two companies In 1984 a further step was made to strengthen the position of the company within the diamond tool industry.

Due to the steady growth it became necessary to divide Dr. Fritsch into two business units, machines and powders, and subsequently establish two separate companies: Dr. Fritsch Sondermaschinen GmbH for machines and Dr. Fritsch GmbH & Co. KG for metal powder.

Dr. Fritsch Metal Powder was the basis for the expansion of Dr. Fritsch GmbH & Co. KG. In the past the priority was to support customers upon request in manufacturing diamond tools. But now the company started the research and development of powders and bonds for different applications.

“Initially we offered our customers only ready-to-use powder bonds. Today our product range includes not only bonds but also raw materials. From A like aluminium to Z like zinc, we provide nearly all raw materials which are used for manufacturing diamond tools, in any quantity and different package sizes,” says Ute Wilkinsson who is charing the managing driector position with Weber.

For several years now, pre-alloyed materials and industrial diamond are completing the product range. Furthermore Dr. Fritsch support their customers with services such as granulating and mixing or even developing powders to customer’s specific request.

h turns 60 In 2002 the siblings Ute Wilkinson and Gerhard Weber took over the management and successfully continued the work started by their father Karl Weber. Further milestones have been set in the history of Dr. Fritsch like the foundation of Dr. Fritsch Machines & Powders Pvt. Ltd. in Bangalore, India in 2004.

Leading edge thinking for new challenges Since the demands of a successful diamond tool production are changing rapidly, future-oriented concepts and actions are essential to cope with challenges. A good example for this is the processing of materials like natural stone or reinforced concrete with diamond wire that has become increasingly important.

In particular the multi-wire saws for cutting thin slabs have an enormous growth potential. For the production of green compacts for diamond wire saws Dr. Fritsch has developed the Bead Cold Press BCP 100. This machine offers a high productivity (up to 18 beads/min.) as well as a constant quality of the beads. In addition, the flexible concept of the machine allows the production of a great variety of bead dimensions.

Another innovation that has been introduced with the

development and production of diamond tools is the use of granulated metal powder and diamond for the cold pressing of segments. One of the advantages of granulated powder is the even distribution in the segment and the considerably reduction of die wear.

By using Dr. Fritsch latest innovation, the Granulating Machine GA 300, the benefits can even be maximized. With an output of up to 30 kg per hour the machine guarantees highest productivity and quality of the granules.

“We would like to face the challenges of the future together with our clients and contribute to our clients success. Finally we would like to take the opportunity to thank all our customers for their confidence and the long-standing cooperation,” end Ute Wilkinson.

The Fragrant Har “Hong Kong is booming and will continue to do in at least another couple of years,” says HD Engineering’s Lawrence Ng. Here wire saws have a special reputation for being the ultimate device for cutting and wrecking.

Since Hong Kong was taken over by China the city has got its own flag.

Hong Kong remains the gateway to China even though Beijing and Shanghai have taken up the competition along with the opening up of the People’s Republic. Hong Kong means the ‘fragrant harbour’ and it is believed that the name comes from the sweetened water around Hong Kong. The sweet water from the Pearl River is mixed with the salt in the bay of the China Sea where Hong Kong is located.

A booming Hong Kong Although mainland China has experienced a bit of set back during the last two years, Hong Kong has and continues to boom. “The market is incredibly good and has been for the last three years. We believe that this will go on for at least a couple more years,” says Lawrence Ng from a hydraulic drill rig manufacturer, HD Engineering, based in Hong Kong. HD’s main business is design / engineering and manufacturing of drill rigs and has been doing it since 1976. But HD is also a distributor for Tyrolit in Hong Kong, as well as Weka drilling systems and Darda equipment.

HD was also a previous distributor for Brokk for over 10 years, but it now manufacturers its own range of demolition robots. They developed their own demolition robot range as a complement to their drill rigs, and have sold quite a number for traditional demolition jobs. But now they only build on request. HD has been selling Tyrolit equipment since 1992, Weka’s drill motors and Darda equipment for over 15 years.

The reason why the construction industry is currently booming in Hong Kong is mainly due to the large number of infra structure projects. Biggest one is probably the Express Rail Link, which is a high speed railway system links from Kowloon (center of Hong Kong) to mainland China, joining the massive high speed railway network there. It is all together a 26 km long link that starts at the new Kowloon station, where there is a number of office buildings and shopping centres, and connections with the subway and the express train from the airport. It is a combination of 12 projects involving hundreds of construction companies. The overall scheme is planned for completion in 2016.

city you see the green scaffoldings that has made Hong Kong famous. They are actually made of bamboo. No other city uses so much scaffolding in bamboo like Hong Kong. Not even in the mainland China bamboo scaffoldings is that common.

Funny thing is that Hong Kong does not have any stock of Bamboo. All the bamboo comes from a southern province

rbour’s Booming The city by night seen from the Hong Kong Island.

Wire sawing systems from Tyrolit Hydrostress is a common sight in Hong Kong and in particular the model SK-SD. of China. It takes long experience and training to be a skilled bamboo scaffolding builder. Even though the bamboo scaffolding looks kind of week it is considered to be much more durable and safe then manufactured scaffolding. To work as a professional bamboo scaffolder has a very good status and the salary is good. Despite this the number of new craftsmen in bamboo scaffolding is decreasing. Young people choose other lines of profession. But telling from the number of bamboo scaffoldings in Hong Kong it still looks like a rather successful business.

Mecca for wire sawing Another construction business that you come across often in Hong Kong is concrete sawing and drilling. In particular is Hong Kong a Mecca for wire sawing. Tyrolit is by far dominating with its Hydrostress hydraulic wire saws which are sold by HD, and the company introduced the wire sawing technology to this city in 1992. At the time, Lawrence Ng has just joined HD, promoting the new concrete sawing technology, and has been involved in this industry since.

Wire sawing equipment has become the ultimate solution for dismantling concrete structures in Hong Kong and the professional concrete cutters here has developed a unique expertise .

Bamboo scaffolding in Hong Kong.

The drive from the city to the airport Chek Lap Kok is very nice over the bridges but takes a bit longer then the express train ride.

It seems like that wire sawing techniques are almost more used then traditional demolition machines like excavators with high-rise booms. This city of 7.2M people is built in a rather

But using demolition robots has become a quite common demolition method in Hong Kong too as many jobs are renovation and refurbishment. HD has played an important role in implementing the method over the years being distributors for Brokk before, so also has the current Brokk distributor C. Crossfield. Controlled demolition methods is popular in Hong Kong due to the environmental and safety issues.

In Hong Kong there are about 10 to 15 reasonable size professional concrete cutting contractors and many small companies doing mainly drilling jobs. Most of the professional ones also offer demolition services with remote controlled robots.

One of the biggest one is DrillCut with about 120 employees and over 30 years of experience. DrillCut works both in Hong Kong and the nearby island of Macau. PDi had the possibility to visit DrillCut’s workshop in the southwest end of New Territories. The contractor, owned by Samson Pei, possesses a gigantic range of equipment from Tyrolit, Husqvarna, Hilti, Darda, Ronda, Pullman, VonArx, HTC, Brokk and HD Engineering to mention a few. PDi reporter even found to demolition robot of the old Swedish brand DMX that no longer exist. Most of the diamond tools come from Tyrolit. DrillCut was Tyrolit Hydrostress’ first customer in Hong Kong, bringing into the market their hydraulic wall saw, wire saw, crusher and burster in the year 1992. “At that time, it was the world latest sawing technology,” tells Lawrence. Besides DrillCut, other large concrete sawing and drilling contractors in Hong Kong are Modern, Advance and Kingland.

When visiting one of the worksites in Hong Kong, I was told that some parts of the city that used to be poor have been and are being transformed into expensive apartment areas. One example in Sham Shui Po that was once very poor but will become one of the upper class areas of the city. Such massive refurbishment projects of course create a lot of job also for concrete cutting and demolition contracts. Another project of big proportions is that all subway and train stations

are equipped with a glass fence along the platform in order to prevent accidents with people falling on the tracks. This project has started with the Hong Kong Jockey Club Station.

HD Engineering’s interesting relationship with concrete Located at a concrete jungle and seeing the concrete poured and then demolished , HD is involved with the civil engineering projects in Hong Kong from the beginning to the end, by supplying the knowhow and equipment to the foundation drilling industry and the concrete demolition industry, having an interesting relationship with concrete. The company was founded by Hans Reiner Fritz, a graduate engineer from Germany, who had the knowhow gained from the experience in the European oil and water exploration fields and foundation industry, together with C.S. Cheng, a local Hong Kong Chinese who is the current Managing Director in the company and had been in the foundation drilling industry for over 40 years. With their practical experience in the industry, HD always see the design, engineering and manufacturing of an equipment as a practical machinery for the contractors to use, with high reliability and performance, which they also see on their distributed equipment such as Tyrolit, Darda and Weka equipment. Furthermore, the company is actively involved with the customers’ projects, as far as operation, application

Hong Kong’s concrete cutting and demolition market

Since the wire sawing method was introduced here in 1992, it has become a standard demolition method for demolition of bridges, diaphragm walls or openings, pier with cutting piles underwater and of big reinforced concrete structures.

“Wire sawing is definitely very popular here and is used for reinforced concrete of minimum of 500 mm thick. For thinner structures wall sawing is more popular,” says Lawrence Ng at HD Engineering.

The HDE demolition robot was designed as a drilling robot built with the KRUPP HB5A hydraulic rock drill and was used mainly for rock bolt drilling use. But when taking off the drill attachment, the robot can also be equipped with hydraulic breaker or crusher for demolition work. HDE can design and manufacture basically the robots based on the customers’ requirements, with power up to 90 HP, or even higher if the tool to be used requires such a power.

The new Kow Loon station and the express train link to China is the single biggest construction project in Hong Kong now and is all together 12 projects in one.

Wet vacs of the Danish brand Ronda.

The TYROLIT wire saw SK-SD is the most popular in Hong Kong, due to its flexibility and high performance. There are over 100 units working in Hong Kong. As for the diamond wire the Tyrolit electro-plated is very popular for high performance sawing jobs and especially for the heavy reinforced concrete. For wall sawing the Tyrolit hydraulic wall saw FZ-4S with their power packs of up to 54 HP is often used. There are also over 100 units in operation in Hong Kong.

HD introduced the electric wall saw to this city since 2007 but it is not commonly used as the hydraulic ones due to the fact that the weather and the operation habit makes the electric wall saw more difficult to use. Yet, the light weight of the electric wall saw is certainly liked by many operators. But last year the new electric wall Tyrolit WSE1217, was introduced with their latest technology P2, which makes the electric wall saws more reliable with higher performance and easy to maintain and service. With quite a number of units brought into this market already, making electric wall saw more popular.

“With the same P2 technology we also introduced the Tyrolit electric wire saw WCE14, which is well received here, and is getting very popular also,” Lawrence adds.

The PDi’s reporter was told that people that visit Hong Kong should consider to visit the countryside also, as it is not just a concrete city, but also a place with lots of unspoilt nature, small fisher villages and mountains.

With so much reinforced concrete in this city it is referred to the, “Concrete Jungle”. The concrete here is probably one of the most reinforced you can find in the world with lots of steel bars and very tough aggregates. Apart from using wire sawing and wall sawing methods, concrete crushing, splitting, and bursting methods is also applied quite often in some special situation, such as in hospitals, hotels, shopping malls, where “silent demolition” is required. So, the hand-held concrete crushers, demolition robots and mini excavator mounted with crushers are quite popular in this kind of situation. Over the last six years or so, the demolition robot has been getting very popular in this area. HD is as mentioned selling the German Darda range of handheld crushers and splitters in Hong Kong.

A wave of launches in hydrodemolition Hydrodemolition is a niche market with only a few specialist manufacturers. But their number is slowly growing and this year there has been several launches of new hydrodemolition equipment. Andrei Bushmarin reports

Some pictures of the new Conjet Robot 557 from Conjet AB.

Below the world’s smallest hydrodemolition robot, Aqua Cutter 410, from Aquajet Systems AB.

Bauma had its usual galvanizing effect on the construction industry. Players from each and every sector came to Munich with a host of innovations. But manufacturers of hydrodemolition equipment seem to have outdone the others with the number of new products.

Conjet to debut a brand-new robot at WOC 2014 At Bauma Sweden-based Conjet showcased the new hydraulic system and digital control systems, which are now integrated in all Conjet products. These two innovations allow for easier manoeuvring, increased performance and more efficient use of power. The pump range was also extended with the addition of two compact 120kW and 170kW models. But the biggest news from Conjet is its new robot 557, which the company is going to launch at the World Of Concrete 2014.

Bristling with new features, the 557 is designed for a variety of hydrodemolition applications. The new machine can be used with both standard and multipurpose arm systems. With the MPA on, the 557 has a reach of 5m. Although primarily intended for heavy-duty hydrodemolition jobs, the new robot can also be employed for more sensitive tasks, in which reach and positioning are very important. Weighing in at almost 3t, it comes equipped with width-adjustable rubber tracks. The control panel with a display has been remodelled and enlarged. But the main benefit of the new control system is that all measurements can be taken with the remote control.

All parameters programmed in the remote control are simultaneously transferred to the control panel on the robot and back. Another highlight is that the chassis can be moved hydraulically. The Robot 557 features a new safety shutdown system, which makes it possible for the operator to shut down the robot and the pump using the remote control. The first version of the Robot 557 will be diesel-powered, but an electrical modification is in the pipeline as well.

50 PDi • Issue 5 • 2013

Pictures above showing the flexibility of the new Aqua Cutter 410 in confined spaces, the kind of applications it was designed for. for indoor hydrodemolition applications and jobs in confined areas like sewer pipes and small tunnels in inner cities. Thanks to its compact dimensions of 2m by 0.78m by 0.99m, the robot can drive through a regular door opening or get inside a concrete pipe. Weighing in at just 1t, it can be installed on scaffolding. With the operating pressure of 700 to 2,500bar and flow of 60 to 180Litres/min, the robot can handle most concrete removal tasks on floors, walls and ceilings.

The Aqua Cutter 410 comes with a number of tools and accessories, including a rotor for surface preparation and work inside pipes, a single lance with a 1.5m front shroud for surface removal and a hydraulically operated articulated arm with a reach of up to 3m. The tunnel operation kit for jobs in tunnels up to 3m in diameter is based on the Aqua Spine system, which allows using most of the existing Aqua Spine accessories. The power control module can be disconnected from the tracked crawler. This allows the crawler to be driven into hazardous environments, like small flooded tunnels.

In this mode, the PCM is remotely controlled. Thanks to this option, users can go on with the work even if the pipe is suddenly flooded. The Aqua Cutter 410 also features the proven equal distance system), the intelligent sensing control and the smart lance system, which have been tried and tested on the Aqua Cutter 710 series.

Chukar Waterjet at OTC Chukar Waterjet is a manufacturer of ultra-high pressure water jetting technology for the deepwater subsea environment, was exhibiting on stand E30 at OTC Brazil, 29-31 October at Riocentro in Rio de Janeiro. Chukar Waterjet is claimed to be the only water jetting equipment manufacturer in the world that offers ultra-high pressure water jetting equipment capable of operating in the deepwater subsea environment. Operable at depths up to 3,000m,

Chukar’s deepwater subsea waterjet system has numerous applications for deepwater emergency response operations, underwater salvage operations, and rapid de-mobilization operations. It can cut steel up to 250mm thick and blast away concrete weight coatings, corrosion and marine growth at pressures up to 3,800bar. Water jetting equipment may also be used to provide turbulence in a stream of methanol for hydrate remediation, an application

Chukar developed in emergency response to the 2010 Gulf of Mexico oil spill, when the company was asked to rapidly manufacture a system to clear a clogged containment system 1,500m underwater.

Unlike conventional tools, water jetting cuts without heat, reducing the hazard of igniting trapped pockets of gas during cutting. Waterjet system tools cannot bind in the cut and can be operated by a diver or remotely operated vehicle making it suitable for projects requiring operations without divers.

Conjet breaks the s Conjet, the well-known Swedish developer of hydrodemolition equipment, has revealed a completely new innovation in the Robot 557 and updated its whole product range with new functions. Jan Hermansson reports

The recent years have been a roller coaster ride for Conjet. An unstable global economy has reduced sales and affected product development. But Conjet has been around since 1990 and has learnt to ride out similar crises. “Humbleness towards clients, the market and competitors is a keyword for us in order to deliver the best possible technical solutions and services to our clients.

Dedication is another, dedication to our technology and the industry is what drives us,” said Conjet sales and marketing manager Lars-Göran Nilsson.

Developing the product range Conjet has a comprehensive and wide range of hydrodemolition equipment divided in jetframes, robots and pumps. Their products are sold worldwide and used on advanced concrete repair projects, such as parking decks, hydropower plants, nuclear plants, bridges, tunnels, quays and other concrete structures.

“Although we have not launched any radically new products for a while, we have introduced smaller updates on our machines over the past five years and we have also introduced our compact Jetframe Nalta, which has been very well received by the industry,” said Nilsson.

At Bauma in April, Conjet introduced a new hydraulic system and digital control system, which are now incorporated on all models. The new system brings many benefits to their products, such as easier manoeuvring and increased performance and efficiency and a more efficient use of power.

And sales of the new models with the new systems have also increased. “We have sold a number of new Jetframes, Robot 327, Robot 367 and Robot 437. The range of pumps has also been extended with two new smaller units of 120kW and 170 kW, suitable for the Nalta, and now have a completely new product range to offer,” said Nilsson.

Robot 557, a true innovation Conjet is now taking a big step forward and releasing the completely new Robot 557, which will be officially launched at World of Concrete in Las Vegas in January. The machine represents a “Our new Robot 557 will be quite an innovation for the hydrodemolition industry”, believes Conjet part founder, owner and sales and marketing manager Lars-Göran Nilsson.

whole new design and technological thinking from Conjet. The machine is built for a variety of applications. The Conjet MPA system is well known and used on the Robot 367 machine and the Robot 557 with MPA has a reach of 5m. A tower attachment will also be available. Robot 557 is for heavyduty hydrodemolition jobs with high volume processing, but also for the sensitive operations where reach and positioning, as well as selective removal are more important.

The robot weighs almost 3t and is equipped with rubber tracks that have an adjustable width from 1.2m to 1.9m, making the robot tower very stable. The design of the body and hood makes it easier and safer for the operator. Also the control panel has been remodelled and enlarged. Its placement provides easy viewing and access. Robot 557

is equipped with the new control system Conjet ONE, which is already incorporated in all current Conjet Robots. The main concept of the new control system is that all configurations can be done from the radio remote control. All parameters programmed in the remote control are simultaneously transferred to the control panel on the machine and vice versa.

Another important feature with the Robot 557 is the robot and pump communication. Now the operator can shut down everything from the radio remote control, including robot and pump. This communication is available as a wireless option, patented by Conjet. The robot is also equipped with a device that enables machine tracking and logging. Reports can be sent directly to the supervisor so the operation can be monitored in real time.

In order to increase the stability of the machine, besides the adjustable tracks, the whole chassis can be adjusted hydraulically, balancing the unit at its centre. This feature is patented by Conjet. A more stable and reliable robot also shortens the setup time of the robot.

The new design has eliminated cables and hydraulic hoses hanging between the machine body and arm. With Robot 557, only four hoses are visible and all hydraulic valves are hidden and protected. The MPA has been re-designed for a smoother movement of the boom system. The first version of Robot 557 will be diesel powered, but an electrical version will be available at a later date. Another big advantage of Robot 557 is its user friendliness. The side hatches of the hood can be opened and lifted like gull wings, or the whole hood can be folded backwards giving complete access to all the inner parts of the machine.

Hydrodemolition robots of this size are normally mated to a 500kW pump, but the 557 has been developed to work with pumps with a power range up to 800kW. All new features and technical solutions on the 557 will be incorporated on the existing Conjet robots by spring 2014.

New faces Two key people involved in the development of the new 557 are The new Conjet Robot 557 is very versatile and is built for a large variety of applications.

Lars-Göran Nilsson sees the future with confidence with a new updated product range and the new Robot 557 to be launched in 2014.

Conny Tångring explains how the new control system sends alerts through its built in device directly to the service technician or a supervisor.

The user-friendly hood was designed as part of their masters thesis in technical design at the Royal Institute of Technology in Stockholm. They are staying on at Conjet to follow the project through to its launch at WOC. “Being directly involved in the design process as a part of the development team at Conjet has been challenging and educating. It is rewarding and fun to see one’s ideas and methods being implemented,” said Ingrid Israelsson. “Having Ingrid and Manfred in our Conjet team is a great asset to our work and bodes well for the development of our existing and future products,” said Nilsson.

Aqua Cutter robot eliminates cost of 50 jackhammer Austrian tunnelling contractor Alpine Bau, working on a section of Singapore’s new Downtown MRT Line, has been able to save on the cost of up to 50 jackhammer operators by using an Aquajet Aqua Cutter 710V hydrodemolition robot system on three of the underground stations.

The machine, from hydrodemolition specialist Aquajet Systems, is the first to have been sold in Singapore, and the Southeast Asia region, by the Swedish manufacturer’s new distributor for Asia, Asia Waterjet Equipment.

Awarded two sections of downtown line Alpine Bau was awarded two contract sections, C917 and C918, of the Downtown Line stage 2 project by Singapore’s Land Transport Authority.

The two sections involve the construction of three new stations and 5.72km of single track tunnels by tunnel boring machine, and a further 445m by cut and cover. The contract value for both sections is S$670.74M (EUR322M). Contract C917 included the construction of the King Albert Park and Sixth Avenue stations, whilst contract C918 included construction of Tan Kah Kee station, which was designed for use by the civil defence in case of emergencies. AWE regional sales manager Christopher Parkhill said that the Tan Kah Kee station, owing to its civil defence status, had extra-deep piling and station walls that are formed from an inner and outer skin.

“There are large surfaces where the concrete has to be removed and the reinforcement rods bent to connect the two walls,” said Parkhill. “The other two stations, which are more conventional in structure, also require the concrete walls to be smoothed and rebar to be freed and bent back.

The contractor had about 14,000m2 to remove and would conventionally have used jackhammer operators. Given the area, and the timescale, it would have needed a large force of contract workers. In the event, the contractor saved on labour by using the Aqua Cutter’s hydrodemolition technique, and improved productivity with the system removing between 110m3/day and 150m3/ day. To achieve this work rate the contractor would have had to use somewhere between 30 and 50 jackhammer operators.”

Average concrete grade was 40, and the Aqua Cutter 710V was removing between 60mm and 85mm concrete thickness on average. Other areas required as much as 120mm to be removed. The 3-D positioning of the front power head gives the operator full freedom to reach all areas. “When obstacles were encountered the machine simply went around them,” said Parkhill. “A jackhammer operator would have been slowed down.”

Using the new 710V robot Aquajet’s engineers, in association with AWE

personnel, trained the Robot’s operators, and the machine was soon working to optimum levels.

“The learning curve was fast, and we were also able to show the Aqua Cutter in action to other companies considering investing in this equipment,” said Parkhill.

The recently introduced 710V robot is a versatile hydrodemolition machine. It is suitable for all operations such as horizontal, vertical and overhead applications. The robot works typically at a water pressure of 1,000bar and flow rate of 250litre/min. It handles removal depths to

approximately 1000 mm of concrete if required and with extended free standing, vertical reach is up to 7m. The latest model also offers a 4m extended working width as an option and track widths up to 1.64m as standard.

Parkhill believes hydrodemolition technology has great potential in Singapore, especially now that the Singapore government is offering grants and incentives for contractors to modernise, and reduce the reliance on contract workers from overseas.

Case excavators help map the earth’s rotation Two Case crawler excavators have been purchased by Kings Bay, a Norwegian government research facility that is run by the country’s Ministry of Trade and Industry. They will be used to provide infrastructure construction and support to the settlement of Ny-Ålesund, on the island of Spitsbergen, including the airport at Hamnerabben. The remote site is the most northerly settlement in the world for research staff.

Two Case crawler excavators have been purchased by Kings Bay AS, a Norwegian government research facility that is run by the country’s Ministry of Trade and Industry.

The excavators will be used to provide infrastructure construction and support to the settlement of NyÅlesund, on the island of Spitsbergen, including the NyÅlesund Airport at Hamnerabben.

geodetic observatory at nearby Brandal. This site will house a very long baseline interferometry antenna, which is part of a global network of VLBI antennas that measure the earth’s rotational speed and how this is affected by solar storms and disturbances.

“We needed a machine to use in the city for smaller digging jobs, so opted for the Case CX130C, but the CX210C was chosen for road construction and ditching jobs, as we will install fibre cables in 2014, so there will be a lot of trench digging in 2013 and 2014,” said Kings Bay technical manager Hallgeir Reitan. “Two new stations are planned for 2014/15 and there will be new roads and trench routes to be built.”

These are the first Case machines that Kings Bay has purchased, though Norwegian Case dealer Dagenborg Maskin has been supplying the company with wear parts for some years.

The location is so far north that in the harsh winter months it will be almost impossible to operate the machines, due to the very low temperatures and strong freezing winds. “We will

“We are delighted to have been chosen as the main supplier for this arduous site application,” said Case Nordic region business manager Lene Thornholm. “The C Series CX crawler excavators have proven particularly efficient and productive, and with the support of our dealer Dagenborg Maskin the Kings Bay organisation can be assured of many years of reliable service.”

Masterton demolition paves way for regeneration In the UK demolition contractor Masterton is helping West Northamptonshire Development Corporation kick-start a new 20,000m2 office development, as part of regeneration pro-

gramme in Northampton. The St. Peter’s Waterside site represents a major part of the town’s redevelopment and encompasses land owned by WNDC and the National Grid. The work includes the demolition of residential properties and commercial buildings across a 2ha site The town centre location has called for careful planning to ensure minimum disruption to the local community. “Throughout the demolition, the safety and wellbeing of the local population and environment is our primary concern,” said Masteron project manager Matt Harvey. “We are ensuring that noise and dust are carefully managed to minimise disruption to residents and nearby businesses. In addition, we’re making sure that the wildlife on the nearby river is protected throughout the project.”

Masterton has also established opportunities to recycle materials from the demolition. The arisings, including bricks and timber, are being separated and 95% will be recycled on site as back fill for the new development.

“Health and safety is a fundamental priority in a demolition Demolition begins on a row of residential properties in Northampton

Demolition starts under the watchful eyes of Peter Mawson and Iain Andrews from WNDC and Masterton project manager Matt Harvey. project of this kind,” said WNDC chief executive Peter Mawson.

“We therefore needed a demolition partner who would demonstrate sensitivity at this prominent, town centre location. Masterton convinced us that they had the expertise to deliver a successful demolition and we’re delighted to have them on board. The demolition work is a symbolic moment for the regeneration of the town, and will pave the way for a flagship office development.”

Masterton will hand the site back to WNDC in December following the 10-week demolition contract.

Within Geneva’s reach Back in the spring, construction and demolition company HTP was contracted to demolish a former government office block on the busy Rue du Stand in Geneva, Switzerland using the first-ever full

factory specification Volvo EC480D-Series high reach excavator.

The demolition created about 2,000m3 of material, and about 900m3 was crushed on site and reused for preparation and construction of the new building. The remainder was taken away for recycling, with only a small percentage going to waste.

The Volvo EC480HR D-Series is Stage IIIB compliant and meets emissions requirements without having to be fitted with an additional exhaust gas filtration system. HTP ordered the Volvo high reach machine last year before seeing the finished product.

“When we made the decision to invest in the Volvo EC480D HR, it didn’t actually exist,” said HTP founder and managing director Yves Huguenin. “The engine was new in terms of emissions, and the hydraulics had been optimised, so we felt it was a good machine

for us and the right size. Furthermore, we knew and trusted Volvo.

Now we have the machine I am delighted with our decision.”

Noise restrictions meant HTP could only work from 7am to 7pm with a one-hour shutdown from 12pm to 1pm, but this was much less of an issue with the Volvo high reach unit, which is much quieter than breaker machines.

The team also ensured the building was brought down safely.

“There was a protective screen for the operator along the front of the four-storey building, but this was only for small fragments and dust and certainly wouldn’t keep out any large pieces of debris,” said HTP site manager Thierry Truffat. “This was a highly controlled demolition process, which required precision and great care. The machine enabled us to conduct a safe dismantling with real efficiency and high productivity.”

HTP was established in 1998 and employs 75 people. It operates 25 excavators, one Rubble Master RM80 crusher equipped with a noise absorber, a 30t high reach excavator and the Volvo EC480D HR high reach demolition excavator. The majority of the company’s fleet is Volvo, with 18 Volvo units in all.

“We chose the Volvo EC480D HR because it was a new machine with a new engine that’s Stage IIIB compliant,” said Huguenin.

“The machine is also strong and provides us with sufficient reach.

When making this investment we looked at several brands and while the pricing was not that different, the Volvo stood out regarding configuration and emissions. Furthermore, we have a long history with Volvo and its dealer here in Geneva, Robert Aebi, and are happy with the level of support we receive.”

Success for Bauma Africa The first Bauma Africa international trade fair took place in Johannesburg from 18 to 21 September. It proved to be the largest industry event on the African continent embracing construction machinery, building materials machines, mining equipment and construction vehicles.

Jessica Hannah from our Africa desk reports.

South Africa’s dominance as a draw for international interest in Africa was emphasised by the success of Bauma Africa, which had exhibits from more than 110 countries and about 14,700 registered visitors. The country is still the most popular foreign direct investment destination compared with the rest of Africa, according to a recent report from Rand Merchant Bank’s top ten African investment destinations.

Over 750 exhibitors Bauma Africa provided an unprecedented platform for increasing business for the provision of machinery to take advantage of the high interest in the continent by fast developing countries such as India and China.

Over 750 exhibitors covered 60,000m2 of indoor and outdoor exhibition space at the Gallagher Convention Centre in Johannesburg.

Africa’s construction sector, along with demolition and mining, provide huge growth stimulation for the continent, given its abundance of metals and minerals, as well as oil and gas reserves. The success of Bauma Africa contrasts with the negative performance of most commodity absorbing economies in the past five years and augurs well for a continent historically deemed ‘dark’ but believes ‘now is its time to shine.’

“The feedback we have received is just fantastic and confirms the outstanding success of the show,” said Construction and Mining Equipment Suppliers Association chairman Lawrence Peters. “Bauma Africa exceeded our expectations by far and extremely satisfied. This show is what we wanted.”

The chief executive officer of local organisers MMI South Africa, Elaine Crewe, reiterated that increased construction and mining activity and demolition in Africa, should mean a substantial increase in businesses providing products and services.

Furthermore, the continued interest of foreign investment into the South African Development Community region’s construction and mining industries may further stimulate growth.

Apart from its exhibits, great emphasis was placed on networking, with matchmaking facilitation services for visitors to contact exhibitors matching their own personal business profile. “This allowed for greater opportunities to set up meetings at the show, saving time and increasing business

growth possibilities that visitors may not have known were there,” said Crewe.

A newsworthy show Bauma Africa received an excellent response from the construction and mining industry at large, with companies showing off their best and biggest equipment, as well as companies seeing the exhibition as the perfect platform to launch new products.

South African company, Pilot Crushtec, released a range of new products. According to sales director Graham Kleinhans, Bauma Africa provided the ideal platform to show the company’s latest crushing and screening products and ancillary equipment. The range contains imported machinery, along with its own range of locally manufactured products, designed and built to meet African conditions.

Meanwhile, earthmoving equipment manufacturer Shantui Equipment Southern Africa of China launched its 48t SE480 excavator and SL60W-3 wheel loader into the African market. “Africa will play an instrumental role in the future growth and development of the Shantui brand, which currently has a total machine population in excess of 5,500 units throughout the continent, of which more than 550 units are in Southern Africa, said Shantui representative Dylan Chicken. “The continent is a strategic market for Shantui. Three of the company’s 10n global subsidiaries are located in Africa, which holds unlimited potential for growth opportunities.”

Hyundai sole earthmoving equipment distributor HPE Africa exhibited and demonstrated a range of 14 machines, including mini excavators, tracked excavators, wheeled excavators, backhoe loaders, wheel loaders, and skid steer loaders. The company also displayed its range of Astra articulated and rigid dump trucks, as well as a selection of McCloskey jaw crushers and screens. “Exhibiting at a high profile event such as bauma Africa has exposed HPE Africa and its product line to some of the biggest names and decision makers in the African construction, demolition and mining industries, which all have huge growth potential,” said HPE Africa general manager Neil Sauls.

South African company Pilot Crushtec saw Bauma Africa as the ideal platform to launch a new fleet of products.

“For the first show there was a tremendous turnout, and we have seen a lot of visitors from North Africa, which is a good sign as we aim to further expand into the African market,” said Ron Stroebel the general manager of Desmond Equipment, the South African manufacturer of the Dezzi range of equipment.

Barloworld Power Industrial sales manager Venash Raghunanan, said that he had been impressed with the attendance of international exhibitors, noting that being able to see some of the competition should increase the competitive edge in the African market. He added that the turn out at the show had been good and was positive about the interest generated from the show as well as the future of Bauma Africa.

“We have been extremely impressed with the quality of clients coming through but would have liked a little more volume,” said Bell Equipment group marketing executive general manager Steven Jones. “However, it has been impressive for the first event.

Bell has been displaying at Bauma Germany for the past few years and Desmond Equipment general manager Ron Stroebel said there was a tremendous turnout for the first Bauma Africa. we are excited about having Bauma in Africa. We are optimistic about the growth of the construction, demolition and mining industries in Africa over the next few years,” Jones added that Bell’s stand had top clients visiting, and his staff valued the opportunity for the company to mingle with its clients.

Caterpillar launches MP300 multi-processors Caterpillar Work Tools is introducing the MP300 series, which is a new generation of multi-processors for Cat hydraulic excavators.

The MP318 and MP324 can handle virtually any demolition job simply by using the basic housing together with a choice of up to six available jaw sets. Other models will be added at a later stage.

“We are applying technologies which reduce our customers’ owning and operating costs to ensure they make more money when they choose Cat products and the Cat dealer network than they can with any competitive alternative,” said Caterpillar Work Tools commercial manager Richard Hermann. “This new generation of multi-processors uses patent pending booster and speed valve technology and a patent pending jaw locking system, which translates to lower costs for customers and lower emissions for

the environment.” Each Multi-Processor can be equipped with a wide selection of interchangeable jaws. These include concrete cutter, demolition, pulveriser, shear, universal, and tank shear. With one common housing and a sets of jaws, contractors can achieve flexibility with minimum investment, and accomplish most tasks encountered on a demolition job. The various jaws can be quickly installed or changed, thanks to a new patent pending jaw locking system. Instead of taking about 25min to change the jaws with the previous series, it now takes 10min with only basic tools.

Cutting and crushing is faster than before. Whenever the jaws meet resistance, an integral hydraulic speed booster automatically kicks in. The new booster design combines a speed valve and new smaller cylinder, which nearly halves the jaw opening and closing

cycle times. In addition the closing force has increased by 6% and will generate between 10% more production on steel cutting and up to 50% more on concrete breaking, claims Caterpillar.

Ausa dumper D1000 APG advantages

Easy and smooth loading of demolition debris is important on demolition sites. Demolition sites are often confined, which makes it important that the loading equipment is designed in a way that the loading machines do not slow the work and that it is safe.

Small compact loaders are often used in interior demolition and renovation projects. These small units do not have that large capacity and sometimes more power and volume is needed. Spanish manufacturer Ausa claims to be the only construction machinery manufacturer offering a 10t articulated dumper for working in confined spaces.

Ausa makes articulated dumpers between 6t to 10t and claims the equipment has the highest skip loading capacity in the market for transportation of demolition debris. They have good rough terrain performance and manoeuvrability in limited access areas thanks to chassis articulation and oscillation, providing permanent contact of wheels on the ground.

The Ausa dumper design offers a rear counterweight allowing full cargo ramp stability, enhancing working safety while protecting against impact. The Ausa claims the D 1000 APG has the best skip capacity and full load gradeability for transportation of materials on steep ground. The wheel reduction differential axles, with integrated and water-tight and free maintenance brakes, allows a high travel speed and gradeability on muddy ground.

The machines also have two cameras with infrared optics for a night vision and colour camera. There is a comfortable and adjustable driver seat with integrated functions operator’s joystick. The machine is equipped with a four speed torque converter automatic transmission powered by a Kubota diesel engine. The Ausa D 1000 APG has a high towing capacity using different hitches.

Deep drilling in Amsterdam In the Netherland’s capitol Amsterdam, the Subway network is being extended with a North South line, which runs under the harbour and the city centre and connects the suburbs with the Central Station and other important locations.

Diamond drilling and wire cutting techniques are being used during the project. These included the new Pentruder MDU high frequency diamond

drill motor to drill eight, 350mm holes at a depth of 2.2m in an obsolete airshaft, which was made of heavily reinforced concrete.

A diamond tipped drill bit set of 350mm with lengths of 500mm, 1m and 2m was produced by the Dutch diamond tool producer Adamas and brazed with Arix segments with thicknesses ranging from 4mm to 5mm. The Pentruder MDU drill motor was used with a 20 KVA, 400V generator.

An extendable stabilisation bar and customised steel base plate were specially produced to provide a rigid guidance for the drill bits as the holes had to be perfectly straight.

D-Drill complete major London project In the UK the London branch of D-Drill has completed a major project at the Deephams Waste Water Treatment Works, in North London, through McGee Group and Murphy Group.

After being involved at the planning stage of the project, D-Drill were called in to detach a series of large sections of the substructure using diamond wire sawing techniques to remove reinforced concrete encased pipes. The work was part of a programme of work that could not slip and D-Drill had to ensure its element was completed on time and on budget.

“Not only did we complete the work within our two-week timeframe, we managed to deliver

with some savings on cost,” said D-Drill London and South Branch manager Jimmy Smith, who arranged for specialist Thames Water Safety Passport training for his team prior to the work. “It was a great team effort and we are delighted at how satisfied the clients were on this project. Once we had detached the concrete sections, they were crushed and recycled for use elsewhere on the site and, thus, it was good for the environment too.”

“The contract went very smoothly and we were very grateful for the collaboration with D-Drill,” said McGee director Owen McGee. The McGee Group has recommended D-Drill to an associate company for further work.

Contractor-pro For manufacturers of concrete sawing machinery, floor cutting will never lose its importance Ranging from conventional walk-behind cutters to sophisticated ride-on types, these machines remain indispensible on construction sites, roads and airport runways. Andrei Bushmarin reviews the latest innovations.

Cost of ownership, reliability and user-friendliness are the three key elements customers ask for when picking a floor saw. As the construction market remains volatile in most countries, contractors tend to cut down on investing in new hardware, preferring instead to rehabilitate and upgrade existing fleets. Ever-decreasing skill level of operators presents another serious problem for manufacturers and end-users alike. Suppliers address it by trying to build more rugged and user-friendly equipment which are easy to operate and hard to break. Some call it contractor-proof machinery.

Innovative power transmission on Tyrolit’s new saw The new Tyrolit Hydrostress 74 HP 3-speed FSD1274*** floor saw boasts an innovative power transmission system.

The re-designed three-speed gearbox enhances the transmission of power to the saw blade’s shaft, allowing for optimum cutting speed and increased blade life. The new floor saw is equally suitable for cutting asphalt, green and cured concrete.

Accommodating blades of up to 1.2m in diameter, it has the maximum cutting depth of 480mm. Ease of maintenance is another distinctive feature of the FSD1274***. Due to the fact that the drive shaft of the saw blade is placed in a maintenance-free oil bath, there are no lubrication points and the driving belts do not come into contact with the slurry.

Powered by an inline Kubota turbo diesel engine, the floor saw offers the possibility of setting the cutting depth electromechanically. An automatic water shut-off system reduces water consumption and increases the efficiency of the machine.

To increase operator safety, the machine has been fitted with an electronic saw blade clutch. A new cover protects the operator from hot and moving engine parts and reduces the noise level.

High-end floor cutters from Lissmac The most distinctive feature of Lissmac’s new Compactcut 600 floor cutter, unveiled at Bauma, is its patented articulated steering. Thanks to this feature cutting and manoeuvring is significantly easier. Precise, lockable setting of the articulated joint ensures that the floor saw never strays from the cutting line.

Another advantage of the Compactcut 600 is that the feed and saw blade have independent drives.

This gives the operator a possibility to shut off the saw blade when moving the machine, which improves their safety.

The Compactcut 600 is available in three options with petrol, diesel and electric motors.

The 600 PV model comes with an extra package for dry cutting. It includes the Vacuum Dry 100 dry extraction sys-

tem, which removes particles from the groove during sawing.

In addition Lissmac has introduced the high-performance hydraulic floor saw Unicut 800. Equipped with a 105kW Stage IIIB-compliant diesel motor, the new model combines high productivity and eco-friendliness. A Lissmac saw blade flange spraying system reduces water consumption to a minimum. A mobile wastewater treatment system helps further reduce the impact on the environment.

Dr. Schulze introduces three new models Dr. Schulze has extended its floor sawing line by adding three new models. The lightweight FS500BSA is a petrol driven machine with the blade positioned on the swivel arm, which also lowers and raises the blade. Thanks to this, the machine’s centre of gravity remains constantly low, improving its stability. The cutting a r m’s d r i ve i s sealed in the swivel arm to reduce maintenance and extend service life. Dr. Schulze has also added the electrically driven FS800E, featuring an ergonomic design and a 11kW motor, which allows cutting to a depth of 340mm with 800mm diameter blades.

The company has also added the large ride-on floor saw FS1200D. Powered by a 37kW Hatz diesel engine, this fully hydraulic machine is designed for cutting concrete and asphalt to a depth of 450mm with 800mm to 1.2m diameter blades. The FS1200D is equipped as standard with a hydraulically operated guiding wheel, a light for illuminating the cutting area and a built-in water pump.

oof floor saws diameter. Also new from Sima is the Trencher 60/70, which is a single or twin blade floor saw that makes parallel cuts in one pass for digging trenches. Cutting width is adjustable, ranging from 600 to 700mm.

The trencher can also be used as a conventional floor saw by fitting the blade on either the right or left side of the machine. By changing the blade guard, it is possible to install 450mm and 500mm diameter blades on the machine.

CS Unitec presents pneumatic walk-behind model

Sima extends Cobra range and launches a trencher Granada-based Sima used Bauma to show four new additions to its Cobra range of floor sawing systems. The Cobra 40 and the Cobra 50 Mekano differ from each other only in terms of diamond blade diameter.

These lightweight and easy to operate machines can be fitted with blades of 350, 400, 450 and 500mm in diameter. The highlights include an elevation system for raising and lowering the diamond blade, augmented by a gas shock absorber and an adjustable rear axle, which allows cutting closer to edges and walls. The floor saws feature the Poly V transmission, which provides a better grip and reduces slipping.

The new Cobra 30 and Cobra 35 Pro, which come equipped with transmission of the same type, are capable of cutting up to 160mm deep with blades of up to 400mm in

The US-based supplier of concrete sawing and polishing machinery CS Unitec has added the pneumatic walk-behind saw CSR 150. Weighing in at 50kg, the saw is easily portable between work sites. A low-maintenance air motor with gearbox eliminates the need to service belts, carburettors or fuel lines. The heavy-duty gearbox reduces the turning speed from 5,250 to 2,900revs/min to regulate blade speed and increase torque to cut hard materials. Rugged steel construction ensures long life and reduced vibration.

The CSR 150 is designed for joint cutting, floor sawing, trenching, road repair and other similar applications. A crank handle raises and lowers the blade for cutting depths up to 200mm. This 7kW saw accommodates blades of up to 500mm in diameter. The machine also features heavy-duty solid rubber casters and a pointer to follow the scribe line.

Since it is air-powered and emits no exhaust fumes, it can be used indoors. Equipped with a water connection port and a splashguard, the CSR 150 is equally suitable for dry and wet applications.

Demolition in underground parking garage in Brazil A large trading company in the city Belo Horizonte, Brazil owns several buildings. One was demolished and replaced with a new seven storey building as headquarters for a mining company. Three floors were underground to cater for vehicle parking. On completion three openings of 2.5m x 5m had to be cut in the 400mm thick reinforced concrete wall dividing two underground buildings.

The cutting of the openings was put out to tender with restrictions of working height of 2.5m between floors and access only by the elevators of 1.1t weight capacity. Due to these limitations most companies suggested using hand held pneumatic breakers. However, the building’s designer preferred the option offered by demolition contractor Demolição Remota.

Demolição Remota proposed using diamond wire to saw cut round three sides of the perimeter, leaving the bottom in place. The diamond wire cutting was performed with a Hydrostress SK-SD wire saw matched with a 20kW power pack.

The sawing was followed by finally breaking out the openings with Brokk 90 and Brokk 100 remotely controlled demolition robots equipped with Atlas Copco SB152 hydraulic breakers.

The Brokks’ low weight and compact size enabled Demolição Remota to easily access the working areas by the elevators.

Each of the three openings generated about 4m3 of concrete and Demolição Remota completed its project in five days working nine hour shifts.

Demolição Remota, founded in 2005, specialises in confined space

demolition jobs all over Brazil and has offices in Minas Gerais and São Paulo state. The company is a division of Servitecnica, a concrete sawing and drilling company formed in 1992. Demolição Remota was the first Brazilian specialist demolition company to use robot demolition machines and now has a fleet of four.

EDA Annual Convention PDi reports from the EDA Annual Convention 2013 held in Milano this summer.

With the key topic ‘Our future’ the European Demolition Association was closing a trend at the 2013 annual convention in Milan this summer. The trend started in 2011, when the association had its conference in London about ‘Our industry’ and followed in 2012, unfolding ‘Our market’ on the convention held in Berlin. During these years the EDA tried to rethink and rediscover the activity of demolition specialists, and now was time to look to the future. And the future is, in the words of EDA past president, Giuseppe Panseri, “not just new equipment, or a new economic context, but mainly a new generation of professionals.” The EDA convention started in the hotel Grand Visconti Palace of Milan, on 20 June. The following day was intensive for the delegates, as the conference had 13 presentations, with speakers and delegates from all over the world. The presentations where divided as follows: Conference session 1 • Renovation and rehabilitation of urban

environments in Europe, Julie Kjestrup, European

Change in presidency After 3 years as EDA president, Giuseppe Panseri handed over this role to Pilar de la Cruz, who will assume this duty until 2016. Panseri, founder of the Italian company Despe, said that it was a great honour for him to serve as president and most specially to see the strength of the association. He also thanked colleagues from other countries and for their support during his term and asked for the same cooperation to be given to Pilar de la Cruz. Panseri will continue to serve on the Board the next three years.

Pilar de la Cruz is a second generation demolition professional, running her own demolition company, Voladuras y Demoliciones, based in Spain. She has been involved with EDA for many years, as delegate and Board member, becoming the first woman and Spanish professional to achieve the role of EDA president. She thanked all the Board members for their support and will focus on the continuous cooperation among demolition professionals and EDA members.

The EDA held an ordinary meeting of its Board, before the 2013 Annual Convention in Milan.

The EDA Board has at least one delegate from each member country, which speaks on behalf of its national demolition association or federation. Also, the members of the international committee have two demolition contractors as delegates on the Board, who act as president and vice president of the committee.

The gala dinner

New and past president, Pilar de la Cruz and Giuseppe Panseri.

The traditional EDA Gala Dinner was held at the Leonardo Da Vinci Museum, with a ceremony to appoint new members to the EDA Club of Honour. The EDA decided to create the Club of Honour

to acknowledge the contribution those former EDA presidents and other prominent members made to the organization and the industry through the years. The purpose of the Club of Honour is to share the experience and knowledge of these special members with new generations of entrepreneurs and company owners.

At the Gala Dinner in Milan,, the EDA Board members from the respective national associations handed out the commemorative medals to new members of the Club of Honour Félix Prudencio, Helmut Roller, Jean Paul Brunel and Jürgen Lippok.

EDA president Pilar de la Cruz, together with delegates of the Board, gave a Club of Honour medal to Giuseppe Panseri, for his great contributions and support to EDA. The Italian demolition association, NAD, has being working hard to bring together the demolition industry in Italy and

Boels progresses into dust suppression The European rental company Boels Rental, has placed a large order with Italy’s DF Ecology for a fleet of their DF Smart portable dust suppression units. The order is for 20 units, which will be dressed in Boels distinctive orange livery.

DF Ecology is a sister organisation to the lighting set manufacturer, Tower Light Srl, and is based alongside the Tower Light manufacturing plant in Villanova d’Ardenghi near Milan.

The DF Smart operates from mains power of 230V, 50Hz 2.2KW and weighs just 77kg with wheels for easy transportation. It consumes water from 3.6 to 5.8litres/min at 2.5bar through a quick release standard water hose connection.

New Cat 836K landfill compactor Successful TüV tests of Atlas Copco Cobra breaker

Tower Light’s Wholly Green Trinity Tower Light UK has added the new generation of lighting sets called The Green 3 which are made up of the VT-Hybrid, the VB9 and the LinkTower.

The newest of this triplet is the VT-Hybrid, featuring a hybrid battery/diesel system, with auto charging technology with the set running on 90% battery power and 10% fuel. The battery is automatically recharged via a low battery monitor system, combining 8-hours battery power and 8-hours generator usage. “’The Green 3’ is our latest contribution to bring to the attention of users of lighting towers the amount of fuel savings that can be achieved by using one, or a combination, of these sets,” said Tower Light UK managing director Paul Hay. “With green issues increasingly at the forefront of a site manager or event organiser’s plans, we believe that The Green 3’s energy saving capabilities will be of keen interest to all environmentally conscious coordinators.”

Atlas Copco Sweden has conducted a comparative study on the comfort and safety of handheld breakers under the supervision of TÜV Nord.

Three tests were performed including a three axis vibration measurement on Dynaload absorber, according to ISO 28927 – 10:2011, a real work three axis vibration test on concrete performed by three operators, according ISO 5349 – 2:2001 and a real impact energy measurement on Dynaload, according to ISO 2787.

Tests showed that the hand-arm vibration value of the Cobra Pro is 3.8 on Dynaload and 5.8 in real work on concrete. Combined with this increased comfort and safety for the operator the Cobra Pro demonstrated a delivery of 61J of impact energy and 1,470W output in the chisel.

The TÜV test results show even better performance levels in terms of hand-arm vibration and impact energy than Atlas Copco had previously claimed. They demonstrate Atlas Copco’s continuous drive for innovation and product improvement that results in higher productivity for customers and increased comfort and safety for operators. Combined with its low emission and noise level the company claims its Cobra Pro petrol-driven breaker is the ideal tool for breaking, cutting, digging, driving and tamping.

Caterpillar has introduced the 419kW Cat836K landfill compactor featuring a redesigned cab, an engine that meets US EPA Tier 4-Final (EU Stage IV) emissions regulations, new wheel and tip configurations, and improved safety and servicing features.

For improved efficiency, the Cat836K can

be fitted with the company’s computer aided earthmoving system. Using global navigation satellite system technology and digital terrain files, the system delivers real-time information from an in-cab display to assist the operator in determining the appropriate number of passes for the level of compaction required.

Hyundai’s new wheeled loader Hyundai Heavy Industries has added the 15t class HL757-9A wheel loader, which is available in three versions. These are the standard model with 2.84m dump height and maximum reach of 1.61m, the HL757XTD-9A high reach version with 3.23m dump height and reach of 1.97m and the HL757TM-9A Tool Master model with parallel mast. This model has a tipping height of 2.84m and a reach of 1.815m. The mast may be combined with various hydraulic quick-couplers.

A Tier 4 Interim/EU Stage IIIB Cummins QSB6.7 six-cylinder engine delivering 149kW powers the loaders, which have fivespeed powershift transmissions with torque converter lockup starting in second gear to minimize fuel consumption.

Standard on all Hyundai wheel

loaders are various modes of operation. With three engine settings, four gear shifting programs and three torque converter modes and other numerous options the loader can be adapted to various applications, such as work in ports, steel mills and recycling operations.

The cabin features 17% more tinted safety glass than the previous generation. The steering column is adjustable in height and tilt to comfort different driver sizes. Standard equipment includes automatic climate control. Handling and reclaiming operations often require large travelling distances.

Therefore, the speed range of the HL757-9A is designed so first gear gives up to 7km/h and in fifth gear up to 40 km/h. Maintenance free wet disc brakes are on all four wheels.

Baier BDB 837 – a big success Innovation has always been part of Baier’s business and a recent example of this is the Bailer BDB 837 wet core drilling machine, which made its debut at the last Bauma.

Baier is wellknown for thigh quality products with less than 0.3% of warranty. Baier is also known for providing

detailed information for its customers, such as the new the 230V model BDB 837 capable of wet core drilling up to 450mm diameter holes. Some customers have even core drilled up to 500mm, but Baier only recommends up to 450mm with the BDB 837.

Creator and Collector of Dust m

Concrete dust suppression and containment is constantly becoming a bigger and bigger issue, which is very positive.

US regulations is fast heading to the level where EU norms has been for a long time. But the US are much faster to put demands of certification and training in action.

Administration’s national emphasis programme on crystalline silica talk of stricter regulations and contractors wanting greater dust collection capabilities. In May 2013 OSHA issued a proposed rule for crystalline silica, which includes revised permissible exposure limits, and is still waiting to push it through.

Ermator USA vice president sales and marketing Fredrik Akermark said that the EPA’s current silica regulations and RRP Rule from two years ago show the regulations in North America are headed to where they have been for years in other parts of the world.

“Equipment manufactures, contractors and regulatory boards all need to work together to make work areas safer,” said Akermark. “New PEL ratings for the construction industry are coming and we don’t know

respirable size particles when workers chip, cut, drill, or grind objects that contain crystalline silica.

Silica exposure remains a serious threat to nearly two million U.S. workers. The most severe exposures generally occur during abrasive blasting and breathing crystalline silica dust can cause silicosis.

OSHA has an established permissible exposure limit, which is the maximum amount of crystalline silica to which workers may be exposed during an eight hour shift. OSHA also requires training for workers exposed to crystalline silica, and requires a respirator protection programme until engineering controls are implemented. Additionally, OSHA has a national emphasis programme for crystalline

how low they will go, but we all need to be pro-active in dust control.”

Manufactures are responding by incorporating dust suppression systems into their equipment. Safety is a driving factor in this increased need for dust control on jobsites. The other main reason is to protect workers and others if the building is open during the renovation.

“Having vacuums connected to equipment collecting dust when working is key,” said Akermark. “Vacuum air flow and type of filter are crucial to collecting the smallest most harmful partials from the air. Current OSHA levels on high efficiency particulate air filters are 99.95 efficiency at 0.5 microns when filters rated at 99.99 at 3 microns are the norm in other parts of the world.”

Collector and creator must match Concrete contractors have to be aware of the increased emphasis on dust suppression in the work place. Not only is it becoming a buzz because of stricter regulations but also it has benefits that go beyond health and safety.

When tools and equipment are fitted with dust containment devises like shrouds and vacuums, the work site stays cleaner. Not only controlling air borne dust that is harmful to breathe, but labour is reduced on cleaning up dust as it settles.

North America is catching up In recent years, the concrete industry has seen an increased emphasis on concrete dust suppression and containment. The US Occupational Safety and Health

Manufactures of air extractors and accessories and the manufactures of equipment are developing innovative ways to control dust. “A good dust collection system can only be effective if the piece of equipment it’s attached to is designed properly. An equipment’s airflow is just as important as having good vacuum, especially when dealing with fine silica dust,” said Scanmaskin USA sales manager Josh Headings.

There are many reports on the hazards of concrete dust. Crystalline silica is a basic component of soil, sand, granite, and many other minerals.

Quartz is the most common form of crystalline silica. Cristobalite and tridymite are two other forms of crystalline silica. All three forms may become

OSHA spec ifies that an e m pl oyer m u s t ‘implement the best possible permanent solution’ for reducing and/or eliminating crystalline silica dust. But in addition to the OSHA regulations on silica dust exposure the EPA’s 2008 lead-based paint renovation, repair and painting rule, aims to protect the public from lead-based paint hazards associated with renovation, repair and painting activities.

must Cope Rent or own?

Clean air for work site safety The rule requires workers to be certified and trained in the use of lead-safe work practices, and requires renovation, repair, and painting firms to be EPA certified. Under the rule, firms performing renovation must use certified renovators who follow specific work practices to prevent lead contamination. In addition to the current regulations the EPA is giving advance notice of the Agency’s intention to regulate the renovation, repair, and painting of public and commercial buildings under section, of the Toxic Substances Control Act. This notice announces the commencement of proceedings to propose lead-safe work practices and other requirements for renovations on the exteriors of public and commercial buildings and to determine whether lead-based paint hazards are created

Report by Dust Control Technology chief executive officer Edwin Peterson is sharing his thoughts about renting or owning your dust suppression equipment.

Demolition contractors across the globe are constantly faced with the question: when is it more cost-effective to rent equipment, rather than buy? The answer is a moving target, calculated according to the needs and finances of each individual company. In Europe, contractors use rental equipment heavily, more than 70% of the time by some estimates. Their theory is to get the job, rent the specific equipment needed to get it done efficiently and then return the equipment when finished.

No maintenance, no repairs. As a result, the contractors know the exact costs for equipment utilization for each project and for similar projects in the future.

Renting can help contractors quickly gear up for large projects, without the lead times that often accompany a new equipment purchase.

40% in renting

by interior renovation repair, and painting projects in public and commercial buildings. For those renovations in the interiors of public and commercial buildings that create lead-based paint hazards, EPA will propose regulations to address these hazards.

All these new and current regulation mean manufactures of concrete equipment for grinding, blasting, coring, cutting, and chipping need to continue working with the dust control companies to fill their customers’ needs. All parts need to work together to develop vacuums and accessories to adapt to the equipment to control the dust, and meet the industry needs head on for safer, cleaner jobsites.

It is estimated that US contractors rent equipment for about 40% of their projects, but that figure has been trending steadily upward. This is especially true in times when jobs are harder to come by and tend to be smaller in scope, and when equipment needs can be more specialized. Capital equipment budgets are often strained during these periods, and financing can be difficult to obtain. For most contractors, there just is not enough steady work to justify ownership unless the utilization rate is somewhere around 65% or higher. Otherwise, that equipment is costing money. Any contractor not currently using a plan to track daily equipment activity should start doing so immediately. While it’s beneficial to project those costs for the coming months, the more valuable data would be to chart the utilization over the past 12 months. If a contractor charges projects for the costs of owning and operating equipment, and consistently recovers them, ownership can make financial sense. But if the expenses of owning, operating and maintaining those units approach the level of income derived, then it may be time to rethink strategy.

Capital expenditures for equipment are seen as a major financial risk during periods of uncertain growth.

When the market crashed, many contractors had to auction off equipment. Some had to raise capital.

Others had older equipment that did not meet current regulations or cost more than they produced. But as markets begin to build up again, contractors are looking for ways to access additional equipment to bid new jobs or find specialized equipment that will position them for entering new markets.

Renting brings many advantages For years the only way a contractor could obtain dust suppression equipment was to buy it. But the advantages of renting can include maintaining cash reserves, controlling budgets, containing costs and adding flexibility. Renting also allows contractors to test equipment under actual job site conditions before investing in a specific brand or model.

When contractors buy their own equipment, they’re either paying finance charges or tying up capital that might otherwise go toward core business activities.

As equipment costs and finance charges rise, renting can

Renting delivers the flexibility to obtain the most appropriate equipment for every project, regardless of scope.

be a more attractive alternative. It may also provide tax benefits. Investing cash for capital equipment can hamper a company’s growth potential and limit the flexibility needed to meet cash flow demands during slow business cycles. Companies with sufficient cash reserves can better withstand economic downturns.

Renting typically requires only a deposit and first-period payment, while even financed purchases often require a large down payment. With access to capital a challenge, renting can free up resources for other needs. In some cases, it may be the only practical option, and it can help manage capital risks. Renting can allow contractors to bid on jobs outside of their normal service area, with dust suppression equipment delivered directly to the job site. Rented equipment can also help meet short-term equipment needs. In some demolitions, for example, dust management is a strict requirement, subject to verification. Renting can help contractors quickly gear up for those jobs, without the lead times that often accompany a new equipment purchase. Rental payments are also fixed and predictable.

What contractors buy when they rent is uptime, performance and reliability. Most equipment is of recent vintage, and rented equipment tends to have low hours. When combined with maintenance schedules and trained technicians, rentals can help contractors avoid breakdowns that require transportation, shop time and/or downtime. The result is stable, managed cost and improved ability to keep projects on track.

Unless a company has secure, fixed-term contracts, future equipment utilization is at best an educated guess. By some estimates, equipment used more than 60-65% of the time is probably more economical to own than rent. Less than 60% utilization can be a financial risk, unless there is sufficient volume and profit margins to cover all costs and maintenance. Anything less than 40% utilization and it is almost always more cost-effective to rent.

Hitachi ZX470LCH-5 scales new heights The first Hitachi dash 5 range demolition machine in Europe has been working on its debut assignment in Munich, Germany. Local contractor B Trinkl confirmed its order for the new ZX470LCH-5 at Bauma and took delivery of the Zaxis excavator in time for the demolition of a former residential building. The site on Lerchenfeldstrasse will make way for the Park Avenue development, which is a seven storey block of 23 apartments.

There is a lack of space in Munich, which is good news for local demolition companies. Developers are turning their attention to the buildings that were constructed after the Second World War and do not comply with the latest building regulations or the modern trends for sustainability and energy conservation.

Single wall fixed with anchor plates The Park Avenue project presented B Trinkl with a number of challenges. There was

only a single wall between the part that had to be demolished and the one to be left standing. This was solved by fixing anchor plates to the retained wall.

The relatively small site was also close to a school, which meant the foundations were removed during the holidays due to noise restrictions.

This was also the stage for the first appearance of the Hitachi demolition machine that B Trinkl purchased from Kiesel, the Hitachi construction machinery dealer in Germany. “The Hitachi is one of five high-reach machines at our disposal,” said Florian Trinkl, who has an equal share of the family business with his brother Baldur and is responsible for a fleet of 30 excavators from 22t to 85t.

“The key criteria for this purchase were simplicity of design, operator comfort and suitability for

our projects,” said Trinkl. “Hitachi offered the best overall package and was one of the few manufacturers that offered a high-reach Stage IIIB-compliant excavator.

Due to the stringent requirements of working in urban environments, we needed a machine that adhered to these requirements. We have had a positive experience with the ZX470LCH-5’s first project, especially with regard to the return on fuel economy.”

“It is beautiful” Andre Niejaki is the operator the new Hitachi highreach model and has 20 years experience in the demolition industry. “My first reaction when I saw the ZX470LCH-5 was just how beautiful it was and I‘m still smiling,” said Niejaki. “It is wonderful, the best machine ever and a joy to operate. It is incredibly well balanced and stable, especially when reaching up high.

I have also been impressed with its precision and works like a dream. It is a well-rounded machine, with excellent control, handling and responsiveness. There has been much thought put into the design, even down to the detail of how the cab is protected and the location of the radio controls. It is the only excavator I have operated in which the visibility has been perfect and I consider this to be a very important factor.”

Weka celebrates its 25th anniversary

Still young and vibrant celebrated German manufacturer of electric tools, WEKA, its 25th anniversary this year by arranging a big party with over 200 guests.

To the right WEKA’s founder and owner Wilhelm Wurster.

The German manufacturer of high quality electric tools, WEKA, has celebrated 25 year in business. The company was founded by the current owner Wilhelm Wurster and is based in Neubulach-Altbulach. The occasion was marked with factory tours demonstrations and evening entertainment for more than 200 guests. The guests came from all over the world, even Russia and USA were represented as well as representatives from county and chamber of commerce and industry to compliment visionary Wilhelm Wurster and his family.

“For our city it is something special to have such an enterprise and hold the efforts of the Wurster family in the highest regard,” said mayor Walter Beuerle to an audience of customers and sales partners from Austria and Switzerland, as well as British, Belgian, Dutch, Italians, Spanish, Poles, Finns, Swedes, Russians, Estonians and US business partners.

An eventful day All guest were impressed by the factory tours and the demonstrations. On the company court, diamond core drills ate concrete, WEKA workers demonstrated how powerful the drilling machines and hand saws are. Many enjoyed themselves on a tour through the small city of Neubulach on the Segway, others talked in the workshop in all kinds of languages about the world of concrete drillers and sawyers.

Wilhelm Wurster described the ecological philosophy during the factory tour. The company produces half of its energy needs by photovoltaic, as it is heated by heat pumps through geothermal energy.

He also said that 45% of the material used in the manufacturing process comes from local suppliers.

Its most important capital however are the staff, Wurster emphasized explicitly. Far into the night the orchestra played for the guests and a magician from Stuttgart entertained the audience. Further more the well-known vaudeville artist Schorsch Bross as well as the jokers Matthias Knodel and Helmut Bachschuster from provided enthusiasm.

WEKA, truly global In 25 years Wilhelm Wurster has extended Weka to an international brand for electric tools. The W stands for Wurster, E for electric tools, K for Kernbohrmaschinen (core

drills) and A for Altbulach the town. Weka is now considered worldwide as manufacturer of high quality electric tools, including diamond core drills, electric saws, core drill rigs and special electric tools for professional users.

The core competence is the production of motors as well as the development and production of electric controls.

The first diamond core drills built in 1988, which Wilhelm Wurster produced on his own in the rebuilt painters shop of his father, is still working. He bought th eunit back from a customer after ten years. WEKA supplies in 34 countries whereby the German market represents 27 percent, Europe 43 percent and the remainder 30 percent.

Among these there are customers in Australia, China, USA, South America, Asia and Africa.

WEKA has 44 employees, among these 16 women, two trainees and three engineers. In 25 years the company has produced and sold 170.000 machines, acquired several patents and has extended already three times the production plant.

Diamantwerk’s trainin

In the Ukraine diamond tool manufacturer Diamantwerk has held a training workshop called 4D positioning of diamond tools for distributors and dealers in Ukraine, Russia, Belarus and Moldova.

The participants had the opportunity to see the latest production technologies of diamond tools on automated equipment. These included a volumetric cold press with the module DiaSet for segments with oriented diamonds; an impulse welding machine for cup wheels and floor grinding tools; the laser welding of segments on discs and drills; SSP machine for sintering segments and an HPSR set for batch pressure sintering for discs.

4D positioning The basis of the training workshop was the presentation of a new concept of assessing the quality of the diamond tools called 4D positioning. In addition to the evaluation of the cutting speed, 1D, the service life of the diamond tool 2D and the unit cost of processing 3D, Diamantwerk focused on the ratio of the minimum cutting speed/drilling in the testing process or the wear of the working layer to the initial velocity.

The fourth indicator - 4D describes the ability of

diamond layer to self-sharpen, which is determined in percentages: •

•

•

•

95-100% is a perfect, stable high cutting performance.

Not less than 85% is a nice, comfortable cutting. Fluctuation from the starting performance down to 15%.

At least 70% is satisfactory cutting.

Fluctuation from the starting performance down to 30%.

The performance drop to 65% or less is assessed as an unsatisfactory performance tool.

Diamantwerk specialists have noted the importance of proper selection of diamond tools with all the operational factors, such as material, processing modes and machinery power, on which ultimately depends efficiency of diamond crystals in the tool. Proper selection can be assessed by inspection of the working surface of the layer.

The optimum is considered when the ratio of the working surface of salient whole diamond crystal to the number of destroyed or partially destroyed, as well as to the amount of fallen out crystals, is 1/ 3: 1/3: 1/3. When this condition is achieved, it usually results in maximum performance and service life of the tool. I such characteristics of the working surface are maintained throughout the life of the tool, it is possible to talk about the ideal ‘self-sharpening’.

In working conditions, the tool’s cutting capacity varies

This means that the cutting speed is gradually reduced from an initial to a certain minimum, whereby under the influence of increasing loads the new active diamond crystals open, and the cutting speed is restored. The amplitude of these oscillations is determined mainly by hardness of the bond and diamond concentration in the tool and abrasive properties of the material.

Diamantwerk implemented advanced production technology with a tool such as DIAFIX with oriented arrangement of diamonds in the working layer, providing high and stable cutting performance. This technology not only ensures 100% maintenance of high cutting performance and resource, but also provides the versatility of the instrument, that is effectively cutting concrete with varying degrees of hardness, abrasion and reinforcement.

The most impressive in the seminar programme were the recommendations on the correct positioning of the tools by the application and performance indicators shown in practice during testing on the site of the plant’s testing laboratory. The presence of a wide range of testing

ng workshop equipment and materials for the test showed the work of the disks and drill for dry and wet cutting/drilling of concrete, granite and porcelain tiles. At the same time there was a comparative evaluation of the cutting speed of concrete with varying degrees of reinforcement in dry mode, using discs made by Diamantwerk and other popular models. A similar demonstration was on the disk continuous rim for wet cutting of hard ceramic. According to the specialists, the cutting speed stability is achieved not only by properly selected recipes for diamond layer of the tool, but also due to the high quality requirements for body cores, which the plant includes in a number of operations, ensuring high precision parameters, rigidity and flatness of the cores. This in turn allows the use of tools with high efficiency at high cutting forces.

At the end of the meeting, participants discussed the main trends in the development of the market for diamond tools, agreed on marketing and technical initiatives and set priorities in the development and launch of new products for 2014 and 2015.

The creators of the diamond tools believe it is important to continue learning to be able to generate ideas and come up with innovative solutions for the effective implementation of the tasks and new developments.

The company’s products include more than a dozen new solutions for the diamond industry. Some of them can be seen on the Diamantwerk Youtube channel.

CSDA contractors combine to create infinite possibilities Multi-million dollar projects and high-profile jobs can be won when contractors combine their skills and resources, as is evident from recent collaborative efforts by members of the Concrete Sawing and Drilling Association.

Just last year, CSDA member Skip Aston of ABC Concrete Cutting in Pompano Beach, Florida, contacted fellow member Tim Beckman of Cutting Edge Services in Batavia, Ohio, to join forces and complete an underwater cutting job in the Bahamas. The two members combined resources to travel to an oil terminal and wire cut a severely damaged steel pier that had been struck by a tanker. “Skip and I go way back and hold each other in high regard,” said Beckman.

“He wanted our underwater wire saw expertise to supplement his team’s work above the water, so we were happy to enter into a joint venture.”

Another recent combination of CSDA member resources has resulted in the successful restoration of a 129 year-old, 9m-tall Civil War monument in New York. CSDA affiliate member Robert Lodge of McKay Lodge Conservation Laboratory in Oberlin, Ohio, enlisted the help of a local contractor member, Matt Gehman of MMG Industrial in Buffalo, New York, to cut and remove the monument for restoration. “McKay Lodge elected to use our services due to our experience in making precision cuts on metal components with our diamond wire system,” said Gehman.

This year has seen even more examples of collaborative efforts from the membership.

Two members combined resources to produce a 1200m 2 polished concrete floor system for a Fortune 500 retail company. In another example, a US contractor member cut free 220m long floating bridge pontoons in Puget Sound, Washington, then referred the customer to a Canadian counterpart when the pontoons arrived in Vancouver for renovation work. The results have been both profitable and successful for all companies involved.

The number one benefit for CSDA members has always been the opportunity to network with industry professionals at quarterly meetings and the association’s annual convention.
