CSDA to Celebrate 40 Years

special survey

CSDA will celebrate its 40th Anniversary

at the 2012 Convention in Maui, Hawaii next March. This major milestone is the result of the vision of Les Kuzmick, Sr. who was instrumental in forming a cohesive group of contractors and manufacturers in 1972. His goal in founding the Concrete Sawing and Drilling Association was to provide a forum to promote the concrete cutting industry, share information and introduce new technologies. Forty years later CSDA has met the initial goals and done so much more. Today CSDA is a nonprofit trade association of 500 contractors, manufacturers and affiliated members from the construction and renovation industry. Its mission is to promote the selection of professional sawing and drilling contractors and their methods. Sawing and drilling with diamond tools offers the construction industry many benefits including lower total project costs, precision cutting, maintenance of structural integrity, reduced downtime, reduced noise, dust and debris, limited access cutting and the ability to cut heavily-reinforced concrete. Times have changed over the past 40 years and today’s sawing and drilling contractors have had to forge a different approach and develop a different business plan to fit today’s technologically advanced and competitive environment. Today’s contractor utilizes advanced equipment and technology to perform sawing and drilling in less time with a lower unit cost. This fact, among others, has allowed the tremendous expansion of the sawing and drilling market. In addition, contractors are also adding

services, such as ground penetrating radar and selective demolition, beyond the traditional services to grow revenue. The original vision Les established has expanded in many ways. The number of services, programmes and member benefits available to CSDA members is outstanding. The list of resources and benefits is long and includes safety manuals and videos, Toolbox Safety Tips, training programmes, insurance programme, promotional materials, online training, website, Concrete Openings magazine, mentor program, field tools like sample forms and worksheets, the slurry analysis, specifications, member profile analysis, convention, discount programs and free World of Concrete registration. The biggest benefit, however, missing from that list is probably the key reason why many belong to CSDA and that benefit is networking. Les hoped that the personal relationships developed by members at the annual conventions and meetings would foster the exchange of information and that certainly has happened. Make plans to join CSDA members 5-9 March, 2012 in Maui, Hawaii to celebrate this special occasion. The International Association of Concrete Drillers and Sawers will also hold its annual convention during that time so have the opportunity to meet sawing and drilling professionals from around the globe. I look forward to welcoming you to the beautiful island of Maui. Best regards Patrick O’Brien Executive Director CSDA, US Concrete Sawing & Drilling Association

The Hilti Corporation has announced plans to buy Eurofox GmbH and has signed agreements with the company’s owners. Competition authorities must now approve the possible acquisition. Eurofox is based in Lanzenkirchen, Austria and was founded in 1993 and has 24 employees. Eurofox is a leading provider of sub constructions for back ventilated cladding façades for buildings. The innovative product range is well established and has until now been mainly sold through worldwide distribution partners. Hilti’s acquisition of Eurofox would allow the company to tap into a further growth segment in the energy efficient construction market. Back ventilated cladding façades significantly increase the level of energy efficiency and simplify the ability to achieve low energy and passive house standards. “Eurofox’s products represent an ideal addition to our portfolio. The substructures they produce will enable us to provide a complete fastening solution for this façade type from a single source,” says Hilti Installation Business Unit manager Peter Rupp. If approved by the competition authorities Eurofox will in the future operate as a Hilti subsidiary. Hilti’s goal is to further strengthen the Lanzenkirchen location in terms of product research, technical consulting and production. Together with the existing team Hilti wants to develop Eurofox to create a worldwide competence centre for façade technology.

Atlas Copco intensifies focus on construction sector On 1 July, 2011, to intensify the focus on construction customers and products and to optimize the synergies between its construction-related divisions, the Atlas Copco Group created a fourth business area, Construction Technique. In the new Construction Technique organization Atlas Copco’s divisions for portable compressors and generators, road construction equipment and construction tools and have joined forces, and are supported by a new dedicated service division. “One of our ambitions is to further strengthen the focus on our construction customers by providing a dedicated organization for all our construction products and services,” says Atlas Copco CEO and President Ronnie Leten. “Construction Service has been created to deliver sustainable growth, both for our customers and our organization. To achieve this we intend to deliver a superior service experience to our customers,” President of the newly formed Construction Service division Adrian Ridge. No major changes will happen overnight to Atlas Copco’s global customer centre organization. In some regions, the combined market size and potential will allow for dedicated Construction Technique customer centress to be opened. “We will only implement changes that benefit

our customers, and only after careful consideration,” says Ronnie Leten.

BuildExpo 2011 in Tashkent TNT Productions, Inc. will organize the 6th international exhibition of building materials and equipment, windows and doors, air-conditioning and heating systems BuildExpo 2011, which will be held on 23-25 November 2011 in Tashkent, Uzbekistan. According to the data of Uzbekistan Statistic Committee from January to September of 2010 the building activity of Uzbekistan increased by 9%. 198 new enterprises were set up producing modern construction and finishing materials including roofing materials, gypsum plasterboards and dry finishing mixes. 42 brick manufactures were opened with total output 232 million pieces in a year. Funds directed to house construction investment grew more than 1.7 times. The key to developing export sales into this largest consumer market in Central Asia is to find the right local partners, who are financially strong, politically well connected and can use their local knowledge to ensure your success. To meet partners and introduce products to Uzbekistan, companies are invited to participate in BuildExpo 2011.

EDA Words from the EDA President

“The Importance of Training” Over time everyone has begun to take notice of the importance of training. Nowadays few would argue that demolition training is a vital component of assuring the safety and well-being of all those involved on a demolition project. Specific demolition training cannot be overlooked when it comes to trying to stop accidents and fatalities on the job, but also in order to be a competitive company with a quality service. Our profession is not improvised and requires a trained and qualified staff, not only to meet regulations but also to master equipment performance, all in compliance with safety rules. As leaders of demolition companies, it is our responsibility to ensure that our employees work under conditions and procedures that ensure and enhance safety. For our staff, training allows the development and recognition of their skills, often overlooked. For our profession, training will help to ensure the future of our businesses; also, it will encourage young people to access to an honorable career and find a professional development on the demolition industry. The saying is “once you’ve made a good selection decision, everything else is training”. Maintaining a well-trained, multi-skilled workforce is more than just an overhead cost consideration, but the recognition that without appropriate knowledge and skills, a company, irrespective of size, can lose its competitive and distinctive edge. Hiring employees that have certified training is important. Also, for new employees in the construction industry taking training helps them to familiarize with potential dangers and hazards that can exist on any site. Even for experienced workers and employers training can be positive to refresh their knowledge. The qualification or certified past training does not take the place of a suitable formative run “in the field” of the worker with a progressive approach to demolition machines. Demolition is a dangerous guild to work in, with high injury and fatality rates around the world. Training staff in identifying and avoiding work site hazards is a vitally important way of reducing the number of incidents. It is crucial for our organizational development and success. It is fruitful to both employers and employees. An employee will become more efficient and productive if he is trained well. Training is the process of enhancing the skills, capabilities and knowledge of employees for doing a particular job. It should be continuous, as the evolving of

demolition technique is, to ensure that all workers know potential risks, but also to learn how to do their jobs in the more sustainable and ecological way, assuring the best quality results for the company and its clients. Each demolition company should pay attention to such a specialized training before allowing its employees to go do their jobs. This is not only the legal thing to do, but mostly the ethical thing, as workers face a variety of potential dangers and hazards each day. The unfortunate trend in short term cost cutting is to reduce or in some cases, completely eliminate the training budget. It’s usually the easiest place to look because training is viewed as overhead costs. The quick slash and burn approach to help bring up the numbers typically results in a return to the hands-on, learnas-you-go, scattergun approach to skill competence. Training is not a ‘recreational’ luxury to be implemented when times are good, but is an essential survival tool when times are pretty rough. It is important to maintain an ongoing assessment of the training needs of the organization while anticipating the changes in the external environment that will dictate new skills and knowledge. So, ‘if you think education is expensive, try ignorance’. In the business setting, that quote meaning, if you think training is expensive, try incompetence. Our business evolves, and we must respond together to this development, in recognition of our profession. At EDA we strongly believe in the value of education of training, and because of this, the technical commission of EDA is working on set up guidelines for the demolition training across Europe.

Words from the IDE President

“Lessons to be learned” Long before I became President of the Institute of Demolition Engineers, I was a keen advocate of the work done by the European Demolition Association. Indeed, during the past four or five years, I have effectively followed the EDA road show across Europe in my capacity as a guest speaker seeking to share information, or as a paying guest keen to learn from my European neighbours. So I was looking forward to the EDA’s long-awaited visit to the UK for its 2011 Spring Conference, timed to coincide with the National Federation of Demolition Contractors’ 70th anniversary. Sadly, and not for the first time, the event largely failed to capture the imagination of my British counterparts. As a result, the UK was generally represented only in a guest speaker or VIP guest capacity and as far as I could tell, the IDE, by purchasing tickets for Vice President Steve Jack, who was making a presentation, and I, was probably one of the largest UK supporters of the event. The reasons for the lack of engagement from UK contractors are probably two-fold. Firstly, as a UK citizen, I will readily admit that we Brits generally think that we know best and that there’s little to learn from our European cousins, but in my opinion, this is a terribly oldfashioned, misplaced view. As a vocal advocate of training and ongoing professional development, I believe that we can always learn more in every walk of life or field of endeavour by listening to others, particularly those others with similar or complementary skills to our own. Furthermore, several of the presentations at the EDA conference, particularly the disaster response speech given by Tom Stahr of Robinette Demolition from

the US, contained information that would be of genuine value to UK contractors. But the fault for the lack of engagement does not rest entirely with the UK contractors who stayed away. I believe that the EDA set the price too high on virtually all elements of the conference. I accept that London is a notoriously expensive city, but the prices for conference attendance and the gala dinner would be considered high at any time. At a time when the industry is adopting austerity measures, those prices seemed border-line extortionate and I am convinced that they are the main reason UK contractors did not attend. Indeed, the cost of a conference only ticket for the EDA event was around twice the price of a ticket to attend the IDE’s autumn conference on Friday 30 September 2011, which will also take place in London, which will also include presentations from the US and Europe, a top quality meal, and which will provide technical content that is at least on a par with that displayed at the EDA event. There are lessons to be learned here. UK contractors must realise that they no longer work in an industry bubble in which British is necessarily best, and the EDA needs to recognise that we’re living in austere times. We missed a great chance this time in London to join together to promote the most highly skilled profession within the construction industry. Let’s make sure that for the next EDA Conference, wherever that may be, we get a reasonable pricing structure to encourage delegates to go to hear the best minds of the demolition industry exchanging information and networking with each other whilst increasing our knowledge at the same time.

Hilti maintains growth Growth at the Hilti Group continued on a positive path over the first four months of 2011 with sales in local currencies increasing by 3%, compared to the same period the previous year. When consolidated into Swiss francs, Hilti Group sales of CHF 1275 million translates into a rise of 2% over the first four months of the current year. This underscores the extremely negative influence that currency effects are having on Hilti’s results. In spite of the different growth rates in the various markets, the Hilti Group’s sales development is distributed quite broadly. The positive trend recently established in North America continued with a rise of 20% in local currencies, where 10% can be ascribed to the acquisition of Unirac. Europe also showed strong growth of 8%, further contributing to market stabilization. Sales in the region Asia/Pacific have also increased by 8%. Above average growth continued in Latin America, with 14% and the East Europe/Middle East/Africa region, with 42%. “It’s very pleasing to note that we were able to maintain the growth trend at this level. But this cannot mask the fact that currency effects remain strongly negative while the rising price of raw materials also poses an ongoing challenge. Therefore a specific cost management and prioritizing of our projects and investments remain necessary,” says Hilti Chief Executive Officer Bo Risberg. “Furthermore we will continue to drive the internationalization of our company and will increasingly focus on developing significant additional resources in the growth markets.”

Holemasters® Scotland burst into Edinburgh A concrete infill feature disappeared from under the eyes of shoppers at Princess Mall Edinburgh, as Holemasters® Scotland burst into the scene. Minimum Disruption A £150 million refurbishment program worth took place at Waverley train station. A concrete wall feature situated between the Princess Mall and the stairs on the Waverley Steps had to be carefully removed with the minimum possible disruption, so that the nearby Princess Mall Shopping Centre and Balmoral Hotel could remain trading without disruption. Difficult Conditions Principle contractor Morgan Sindall chose to use Holemasters® Scotland Ltd, professional concrete drilling and sawing contractors. Taking into consideration the location and challenges the project entailed, Holemasters® proposed the use of Diamond Drilling and Hydraulic bursting techniques, minimising noise and dust pollution. Speed and Efficiency The job began with 190no. 112mm diameter cores drilled into the structure, up to 1.3m deep. Holemasters® Scotland used their long experience, to place holes in a pattern that would maximise the burst with the least possible holes, allowing for more efficient and safer removal. With such a large amount of holes to be drilled, Holemasters selected the Aero® Core Drills for maximum speed of cut. After testing, Holemasters® also found the Aero® Core Drill to have excellent life, saving tool costs throughout the project. Care for the Environment Holemasters® Scotland have a commitment to safe guarding the environment. This commitment was upheld throughout the job by collecting the cement slurry at source, and decanting it into 1m3 containers during the drilling operations. This was then removed from the site and turned into cakes for disposal at a later date.

Care for Surroundings On completion of the coring, a 4” hydraulic bursting head was inserted into the formed holes, creating 120 ton of force driven by an air cooled power pack. Holemasters® had to consider the masonry wall situated directly at the back of the concrete infill. With this in mind, operators were careful to burst out to an open edge. Project Success After only a few days of operations, Holemasters® Scotland Ltd removed 156 tons of concrete with no disruptions to the close by businesses – a very satisfactory end to a large project. More Information Holemasters® Scotland have recently moved into large new premises, with purpose built offices and a large workshop area. More information about the company can be found on www.holemastersscotland.co.uk. The Aero® core drills used successfully on the Waverly Station project can be sourced from www.aerodiamondtools.com.

The Brokk Monster Machine Brokk, a leading manufacturer of remotely controlled demolition machines, has introduced its most powerful demolition robot the Brokk 800. More than twice as big as the previous top model Brokk 400, it meets customers’ demands for longer reach and higher capacity, especially within the tunnelling, mining and metal processing industries. The Brokk 800 is available in two models, Brokk 800 Standard and Brokk 800 Process, where the latter is especially designed for complicated demolition jobs in hot environments. “Furnaces and ladles in process plants are getting bigger and larger tunnels are also being made, which calls for heavier equipment. The Brokk 800 is our response to these customer demands,” says Brokk Group CEO Martin Krupicka. The new Brokk weighs 11 t and has a reach of approximately 10 m. It has more than twice the hitting power of the Brokk 400 and can also carry twice as heavy equipment, such as buckets, beam-grapples and drilling equipment. It is a very compact machine for its power with the same capacity-to-size ratio as the rest of the Brokk family.

Two models to choose from The Brokk 800 Standard version features Brokk’s

signature three arm system, exceptional reach, and delivers a phenomenal punch equipped with a MB1000 breaker. The Brokk 800 Process version features an arm with a specially designed breaker with 360° rotation, making it possible to work at a perfect angle, regardless of where the demolition power is needed. The breaker has a hit-bend-and-break function, enabling perfect control when cleaning out ladles and furnaces. It also has special heat protection for work in hot environment and advantageous for the process industry where short process downtime is essential.

Can replace several machines “The Brokk 800 is a machine that can perform many different tasks, making it possible to replace several other specialized machines with just one,” says Martin Krupicka. “With the precision and safety of using a

remote control and Brokk’s premium performance and quality, the Brokk 800 delivers great value to Brokk’s increasingly sophisticated customers.”

Great potential The Brokk 800 Standard was officially launched at the World Tunnel Congress in Helsinki, Finland at the end of May, and the Brokk 800 Process was introduced at the Metec exhibition in Düsseldorf, Germany at the end of June. There has already been considerable interest from customers. “We already have orders for the Brokk 800 and it is clear that our customers consider this an important addition to the Brokk range. It is a great leap to the really heavy jobs in industries in constant search for more flexible and cost effective solutions,” says Martin Krupicka.

Bulls eye topics at well-organised EDA conference

The annual European Demolition Association conference held on the 2-4 June at the Royal Horsemen Hotel in central London, was a well-organised event with first class topics essential for any demolition contractor. However, the EDA might need to adjust their sights to cater for the needs of as many European contractors as possible. About 140 delegates from national demolition associations around Europe attended as well as a similar number of supplier members. The first day was set aside for a board meeting, national association meeting and technical committee meetings. In the evening a cocktail party, sponsored by the Italian manufacturer Mantovanibenne, was arranged

The following day was open to all participants and the sessions started at 9 am with an opening ceremony held by Giuseppe Panseri and EDA’s new general manager Jose Blanco. The day contained a series of very interesting presentations. First up was UK’s NFDC General Manager Howard Button talking about High Reach Training. The UK association has put together a comprehensive guide and training plan for high reach demolition, which is now used extensively by demolition contractors throughout Europe. Programme manager Steve Jack from MAGNOX D&D provided a lot of advice about the complex demolition of Power Stations. This was followed by Senior Researcher Iñigo Vegas from Spanish company TECNALIA demonstrating the innovative strategies for high-grade material recovery of construction and demolition waste at the IRCOW Project. The second session of the day started with BRE Principal Consultant Katherine Adams giving a talk on “Demolition waste: now and in the future”. This was followed by the presentation of an interesting demolition job presentation made by Steve Blenkinsop, pre-construction manager with the UK demolition contractor ERITH. This particular demolition project took place in a building in the centre of London in an extremely sensitive area. The job was carried out to great satisfaction from neighbours and shops in the area. A pub in the building that was actually being partially demolished was able to stay open throughout the whole demolition period. Next speaker were Daniel Rieber from Italian Ferrari Demolition who presented the new Ferrari demolition system. Last speech before lunch was about the EDA history conducted by David Sinclair, associated with SAFEDEM The EDA board meeting.

highlights of the conference when US Demolition Association‘s Executive Director Michael R. Taylor and US demolition contractor Robinette Emergency Response Division Manager Tom Stahr spoke over the subject “Managing a Crisis at Your Company and Emergence Response Demolition.” A very interesting conference day ended with an interesting round table discussion focusing on the question “Where is my profit?” Questions and concerns about the demolition industry, the economic situation and the challenges to be profitable were aired. Participants at the round table were: Don Rachel, US Demolition Association’s (NDA) President, Gary Bishop, UK National Federation of Demolition Contractors (NFDC) President, Marcel Schroeder, German Demolition Association (DA) Official EDA Delegate, DE Jan Bork, VERAS President, NL Daniel Midavaine, SNED President, FR Caterpillar Neil LeBlanc.

EDA’s treasure with great potential The 2011 EDA annual meeting was very well organised. In particular the new EDA secretariat headed by José Blanco did a professional job bringing a strong focus on the core subject within the European demolition industry and its participants. On the negative side was undoubtedly the high cost of attending, which might partly explain the weak participation, particularly from the UK and also the Nordic countries. Demolition contractors are generally down to earth people who of course enjoy a classy and stylish event once in a while, but the cost for this annual meeting took almost the prize. It was disappointing that for instance

not a single demolition contractor from Sweden or the Swedish association attended. I was surprised and disappointed that there was not a Swedish demolition contractor making a presentation about a complex demolition project in a Swedish nuclear plan or another complex industry project. There are lots of interesting projects that could have been presented at the meeting and the absence of any presentations from Sweden is the responsibility of the Swedish association. Frankly, shape up Swedes and show what you can do. The EDA has great potential but needs to invite a bigger audience. The EDA, as the umbrella association, needs to find new ways of reaching out to the European demolition contractors. EDA would benefit from becoming a wider and more open association approaching all kinds of demolition contractors from small local entrepreneurs to large pan-European contractor chains.

“IACDS DOES A GROOVY JOB IN BRUGES”

The traditional IACDS group photo.

The International Association of Concrete Drillers and Sawers’ caravan keeps rolling through Europe. This year it set up its camp in Bruges, Belgium, a United Nations Educational, Scientific and Cultural Organization World Heritage Site since 2000. The multinational mission was greeted by representatives of Bruges City Council, which reflects the growing acceptance of the industry on a level beyond concrete sawing and demolition. PDi’s Andrei Bushmarin reports.

Bruges is a beautiful city and the Markt, the Belfry, the Church of Our Lady, canals and masonry arch bridges create a unique blend of medieval grandeur and small-town cosiness. It is surprisingly neat and clean, despite the hordes of tourists streaming through it every day, summer or winter. Bruges has a history that dates back many centuries, and the first excursion to it was given to IACDS delegates by the members of Bruges City Council themselves. This was a good start to the intensive one-day meeting where a wide range of issues was discussed.

Keeping the membership up The IACDS roster keeps growing. This year the association was joined by the French SNED-SCBD, in the category ‘smaller associations’, and the contractor ReverR from the Czech Republic as an individual member. IACDS has a long history with the French and the association held one of its meetings in France in 1995. Those early discussions did not result in membership, but the seed was planted. Now 16 years on, the 2008-formed SNED was voted unanimously to become a full member of IACDS. SNED currently counts 35 members and focuses on job training and educating specifiers in concrete sawing techniques through video presentations.

Waiting for 2013 to come Without doubt, 2013 will be a big year for the industry, with Bauma, as the mainstay event, providing the ideal background for IACDS activities. The association will use the show as a springboard for its projects Diamond Award and the second seminar on concrete sawing and drilling techniques. The Diamond Award issue caused a prolonged discussion. The

24 PDi • Issue 3 • July - Aug 2011

competition needs reinvigorating as the drop in entries and the same names on the winner lists over the years are clear evidences of that. Contractors’ reluctance to share their knowledge with competitors as well as their tendency to concentrate on finding the next job, rather than advertising a completed one, were cited as the major obstacles to organizing a good contest. To give the competition a second wind, the meeting agreed to lift any restrictions on the entries and to begin the promotion campaign well in advance. The concrete sawing seminar, which in everyone’s opinion was a big success, will be repeated at Bauma 2013 with a slightly different focus. Martin Godickemeier of Hilti floated the idea of adding contractor speeches to the seminar agenda. As Martin pointed out, this would make the programme less high-tech and more down to earth. To organize the event, an advisory panel of seven delegates headed by Jose Blanco was put together. As IACDS members are justifiably proud of their linguistic abilities, it was decided to forgo the services of professional simultaneous translators and re-enact the hilarious experience of interpreting the speeches themselves. That alone makes the seminar a must-visit event.

C’mon, let’s groove now! In 2007, IACDS started inviting speakers to give lectures on the industry-related subjects. Both speeches made in Bruges revolved around grooving and grinding. Frank Zuzelo of Pennsylvania-based Cardinal Grooving presented an in-house technology of grooving airport runways. Airstrips are usually grooved to reduce hydroplaning, or water pooling that may jeopardize aircraft landing. The conventional approach

Cardinal Grooving offers an alternative technique of trapezoidal grooving. This technique has a number of advantages over the traditional method that include reduced tire wear, superior drainage and increased pavement life. John Willis of Tyrolit UK was in the groove too, but his presentation dealt primarily with grooving and grinding roads and motorways. His general conclusion was that the market potential for this equipment is huge in England, not the least thanks to the government that introduced a 10-year plan to overlay every concrete highway found guilty of noise pollution.

Princes and paupers This year’s market reports were reminiscent of a rollercoaster ride: from the lows of Spain where the situation is so dire that it is about time to call for a ‘Spain relief ’ campaign to the highs of Switzerland and Sweden that were almost apologetic for doing well. In Germany and Austria, the industry is in good shape too, whereas the UK market saw a 40% drop, with a good number of companies going bust and the DSA apprenticeship scheme coming under heavy pressure. North America posted a 14% decrease in non-residential construction contract value and a 17% one in residential construction on the similar three-month period in 2010. The Russian market is still down, so are the plans on the creation

A minute of silence and respect When Japan’s delegate Norikazu Shibuya flashed up the photos of devastation caused by the earthquake and tsunami, the audience gasped with shock and disbelief. The sheer scale of the disaster is beyond comprehension. If that was not bad enough, these natural catastrophes were followed by the Fukusima meltdown. To commemorate victims of the tragedy, delegates observed one minute silence. John Willis of Tyrolit UK told the meeting about grooving and grinding roads and motorways.

As usual there was also some quality time at the pub.

The simple translation is believed to be “raise your glass!” and Jose Blanco has a good reason to do just that. This young man has added IACDS to the extensive portfolio of various associations he manages or chairs. The Spanish AEDT has been very active since the day it joined IACDS, and now its spokesman’s efforts were rewarded with presidency. Norikazu Shibuya and Lars Sandstrom from Sweden were unanimously elected VicePresidents. By comparison, the voting on the next meeting’s location turned into a full-on derby between the delegates who wanted to join CSDA in Hawaii and the ones who preferred to stick with Europe. As votes split 50/50, it was Peter White who exercised his right as incumbent President and swayed the balance in favour of Hawaii. “Mahalo, Peter, for this parting present!” It is bound to be an unforgettable experience even for those who were initially reluctant to go. The conference is scheduled for early March 2012 to coincide with CSDA celebrating its 40th anniversary.

About Euro 10.6 million will be invested in refurbishment and renovation. The demolition contractor Riv & Sanering has been hired for the renovation. Seven Brokk machines are being used on the project and recently three more were purchased. The Stockholm based demolition contractor Riv & Sanering has been contracted for a variety of tasks in which the basic reinforcement work is the most comprehensive. Seven Brokk machines have been working in the basement of the southern part of the Grand Central Station, spread over a Brokk 260, two Brokk 180s, three Brokk 90s and a Brokk 40. And three more have just been purchased.

Removal of foundations and reinforcements Much of the work has been to take away concrete foundations, reinforcing the old cold wall, which in places is up to one metre tall and as wide. The old foundation wall in granite is over 100 years old. In addition there is a lot of bulldozing work for moving large amount of fill material. This is for the developer Skanska to provide access. In many places the bulldozing it down to about 1.6m below the basement level, so the groundwater level had to be lowered in some places by drainage pumps. “There is an old lake bed under the Central Station and it shows. In the bottom, we often encounter sharp stakes thrust into the mud and they represent an important gain in itself,” says Riv & Sanering President Tony Westman. Besides Brokk Riv & Sanering has four Bobcats and a self-loading dump truck to help with unloading. All machines are equipped with hammers, shears, buckets and grapples. A large number of cracking devices and a special drill rig for the Brokk machines are also used on the job as well as numerous concrete sawing and drilling equipment. Riv & Sanering has 10 men on the job and will have need of the same strength throughout the project. In addition, sister company Betongborrarn in Sol-

lentuna has 10 concrete cutters on the job. Among other things, they had to do some wire sawing. At one point, a passage was drilled 3.5 m long and 500 mm in diameter. It is difficult to estimate the material to be excavated, but it has been suggested approximately 6,000 m3 of mixed material will be removed. Riv & Sanering has removed about 120 t/day, which has been sent by trucks outside the town. All concrete recycling is carried out by Riv & Sanering while other types of excavated spoil is tested for any prohibited substances. Testing is the responsibility of client Jernhuset .

cracking work were previously made by hand, which was heavy and time consuming. The Brokk drilling system saves the operators and time.

Good order in a tough job Supervisor from Riv & Sanering is Stefan Lövestedt who has extensive experience in the demolition industry. “Everything has to run smoothly and perfectly. It puts high demands on the crew and they are doing an excellent job. Here, you cannot relax for a moment, but the concentration must be on top all the time, although it might not be as fun to crawl into a dark and wet basement when it is summer and the sun is shining outside,” says Stefan. This type of city job sets high demands on those involved. It is cramped for space, lots of people, logistics must work properly and the whole time there is constant movement of people and machines. Tom Kallio from the company Mätteknik & Anläggning, acting as surveyor, drilled, piled and excavated the job. “Tom is simply invaluable on this project,” says Stefan. “Then I would add that it is also Stefan himself. Without his supervision and expertise, combined with our other talented staff from Riv & Sanering and our sister company Betongborrarn this complex job would not have worked out so well,” says Tony Westman.

Thankful to the Brokk machines Important assets on the job are the Brokk robots that take on very complex tasks and applications. In February 2011 Brokk AB delivered three new machines to the worksite. The order included two Brokk B160s and one Brokk B90 with the new special Brokk drilling equipment. The B90 with the drill rig is mainly used to drill holes for the cracking devices. Holes for the Issue 3 • July - Aug 2011 •

Refurbish your floor instead of replacing it

During the Pulire show in Italy in May, HTC Sweden launched a new version of the floor renovation system DCS Hybrid. The eco-friendly DCS Hybrid system is a problem solver for the stone floor renovation industry as damaged and heavily worn stone and terrazzo floors easily can be brought back to original quality and shine. Stains, scratches and orange peel are removed using the DCS Hybrid tools on ordinary cleaning machines with only water. The lifespan of the new DCS Hybrid system has increased significantly to at least double the lifespan of the old system. The micro scratch

pattern is also improved and the system has a much better, overall grinding performance. The system includes two new tools, the DCS Hybrid Black and DCS Hybrid Red. DCS Hybrid Black is the coarser of the two tools and removes minor scoring, excessive wear and stains. The less coarse tool DCS Hybrid Red removes scratches, wear and stains. DCS Hybrid Red, which prepares the floor for further treatment with Twister, can depending on the floor’s condition be used without prior use of DCS Hybrid Black.

Husqvarna unveils K1260 power cutter Husqvarna Construction Products has introduced the K1260 power cutter. With the addition of innovative features, the K1260 can keep running longer and harder. The K1260 follows the K760 and K970 power cutters and new features include:

• The K1260’s engine produces more output, 7.8 hp, and the built-in automatic filter compensation unit, SmartCarb, helps maintain high power and lowers fuel consumption. •

New Micro-trenching Technology by Rellok

Micro trenching is an alternative method to the traditional technique of digging up roads with mini excavators or similar equipment for laying fibre optic cables and other underground services. There is no overcutting or jagged edges, as micro-trenching uses diamond saw blades, which make straight cuts through the road material to form precise joints with the existing and new surface of trench infill material. This is a quick procedure with no overcutting and only removes the material that is actually required for the cable package and surrounding safety materials. Rellok cutting solutions GmbH located in Celle, Germany, offers a floor saw that is exactly modified for this intended use. The basis is the fully hydraulic floor saw RSF 750 with a 75 kW engine. All operational functions, such as traction and cutting shaft, steering, and saw blade excavation are driven by a high-performance hydraulic system. The speed of the cutting shaft can be adjusted continuously between 700 and 2,500 rpm and is ideal for blades with diameter from 350 – 1,500 mm. Easy • •

of the market’s most efficient air filtration systems. It delivers operational dry cutting of about one year without filter service required. The Poly V-belt provides better power transmission, less retensioning and increased product life. The DEX dust-handling system provides cleaner cutting with less water usage.

The K1260 is the perfect tool for municipalities and local governments’ water and street maintenance crews. It can cut pipes in installation work, concrete and masonry in alteration, renovation and new construction work as well as asphalt in roadwork and pre-cutting for pipe trenches. When used with the KV 1260 cutting cart, it can be used for flat work.

operation and safety technology are state of the art. The emission class standard is in accordance with EC-NRMM Stage IIIA / EPA Tier 3. The floor saw had to be modified for microtrenching. The blade guard is wider and includes a new water nozzle system and the nozzles can be operated individually. This ensures an ideal ratio between the cooling of the saw blade, binding of dust and water consumption. The removed material is just moist enough to minimize the development of dust. Scrapers attached in and behind the blade guard assist in keeping the joint virtually residue-free after cutting. The cuttings are pushed to the side and can be easily removed. The joint, up to 250 mm deep and 25 mm wide can be created in one work process. For this reason, diamond saw blades are used, which have been especially developed for this purpose by Rellok. The heavy weight of the blade package creates an extremely high shear force in the area of the cutting shaft stump. Immediately after cutting, the cables can be laid and subsequently the joint can be sealed. Micro-trenching presents a very quick, clean and cost-efficient solution for the subsequent installation of communication cables in existing areas made from asphalt or concrete.

Getting the job done with the new Versa-Cut Turbo bit Husqvarna Construction Products is proud to unveil the latest addition to their lineup of diamond core bits, the Husqvarna Versa-Cut Turbo. The Versa-Cut Turbo bit features a turbo segmented shape, which promotes high productivity for completing wet drilling jobs quickly. The bit has a 1-1/4”-7 adapter, a 14” drilling depth and is available in a range of diameters from 2” to 8”. The Versa-Cut Turbo is a general purpose bit made to cut a wide variety of materials. It facilitates fast and smooth drilling of concrete with or without steel reinforcing, brick, block and stone materials. This broad range of applications makes the Versa-Cut Turbo bit the right choice for drilling jobs.

Success for Ashine After repeating improvements in the formula and field tests, Chinese manufacturer Ashine has announced that its resin-bond polishing technology is reaching the world’s leading level. One important proof is the resin-bond polishing pads from 50 grit to 3000 grit. “In the comparison tests against the resin polishing pads from one major European brand, Ashine’s pads achieve similar polishing performance and final gloss. It is believed that Ashine is the first manufacturer in China, which can achieve this similar performance. Based on the performance, another advantage of Ashine’s pads is long life, which is around 1,400m2/set, while the European brand only gets 1,020m2. That means Ashine’s resin polishing pads are 30%-40% better on performance per dollar,” says an Ashine spokesman. A big US wholesaler and one of their clients that uses one of the biggest brands in Europe but tried Ashines polishing pads on a 370m2 job was very happy with them. The client said that they cut just as fast and polished just as well as the pads they used before. “Feedback from several other customers who tested the new formula polishing pads also shows that the polishing results of Ashine’s 800 grit are similar or better than the 3000 grit pads from other Chinese manufacturers, on the clarity and gloss,” says an Ashine spokesman.

The new Titan from Braun

The Austrian concrete cutting equipment manufacturer Braun Maschinenfabrik sticks out when they state strong advantages between their own Titan series and competing brands. First the Titan series has a low motor speed of 6,000 rpm instead of 30,000 rpm, thus high life expectancy, high operational safety and low maintenance costs. The motor has high torque at low speed even from standstill, thus saw blades up to a diameter of 1,500 mm can be run with high performance. The Titan wall saw has also a low weight. “Instead of minimizing material thickness like most competitors do Braun reduces weight by using low weight materials like Titanium,” says a Braun representative. In case of a failure, Braun is able to log into the Titan control unit to check the tele-diagnostic service and tele-maintenance system via mobile radio-communication in order to detect the cause of failure. The latest program versions of the automatic control system can be transmitted at any time to any control unit or parameters can be modified for special applications. The Titan just like all Braun wall saws can be 05.03.2010 11:51 Uhr Seite 1 used with various track systems, such as Hilti and M A S C H I N E N FA B R I K

Rocester’s “Haunted House” demolished in safety move

Caption: A JCB JS220 tracked excavator fitted with a selector grab moves in to demolish The Rookery, in Rocester, Staffordshire. In the UK a wooden house, which has graced the skyline in Rocester, Staffordshire, for almost 125 years, has disappeared from view on safety grounds. The Rookery was built around 1887 as a winter retreat for local businessman Charles Hartley who owned a local brick and tile works. It

was constructed mainly of Swedish pine, which, at the time, was forecast to have a lifespan of just 25 years. Now two JCB machines have been commissioned to demolish the building. First a JCB 540-170 Loadall telescopic handler complete

with man basket was drafted in to enable the initial brick-by-brick demolition of the chimney stacks before a 22 t JCB JS220 tracked excavator with selector grab completed the demolition of the building. In later years The Rookery, which was

bought by JCB in 1969 and was close to the company’s world headquarters, earned the nickname ‘The Haunted House’ from local people because of the eerie outline it cast against the sky. In the days leading up to the demolition JCB set up spotlights to shine into the building to deter birds from roosting. A JCB spokesman said: “Time really has taken its toll on The Rookery and despite regular security patrols and a fence around the property, there has also been an increasing problem with youngsters entering this dangerous structure. The Rookery was in such an unsafe condition that the only option was to demolish it before anyone was seriously injured. The 540-170 Loadall and the JCB JS220 excavator are more used to operating in much more arduous conditions and made light work of this particular project, with The Rookery demolition completed in two days.”

Selected for salvage at sea Three Hitachi Zaxis excavators are helping clear one of the biggest ship graveyards in the world. Around 300 vessels have been abandoned in Nouadhibou Bay, Mauretania, over the past 20 years.

In a bid to regenerate the crowded port, an operation is underway to clear the decaying wrecks, which range from 200 to 1,200 t. The three ZX870-3s will be used by Dutch company Mammoet Salvage to remove and break 70 of

the floating carcasses. The European Union is investing EUR 28.8 million in the project, the aim of which is to clear the waterway for the fishing and industrial maritime traffic in the area. The graveyard has

caused the shipping industry to decline in recent years, as the shipwrecks pose a hazard to the environment and their surroundings because they contain dangerous substances, including oil residues, asbestos and insulation materials. Work on the project has just begun and is expected to take 22 months. The Zaxis excavators will be used by Mammoet Salvage to break the ships into smaller, more manageable pieces. The ZX870-3s will be working from a pontoon, as the vessels are all anchored out at sea. The machines were modified and supplied to the customer in just three weeks by The Netherlands’ official Hitachi dealer, Hitachi Construction Machinery (Europe) NV (HCME) Domestic. Each ZX870-3 was fitted with a cutting tool and had its arm extended by 1.5 m. Counterweights of 5t were fitted to ensure they would safely handle large pieces of metal. The machines were also fitted with tracks designed for use on the pontoon. “We were able to supply the three ZX870-3 machines quickly and to the correct specification, which was of course important to the customer,” says HCME Domestic PR & Marketing Coordinator, Esther Navest. “This is a significant project and will reap both environmental benefits and economic rewards for Nouadhibou Bay and the surrounding area.”

Diamond wire for recycling metal blocks Recycling is an important business sector, particularly companies which are producing metal based products wanting to re-use raw materials, especially those with high market prices like copper. During the different production processes, raw materials will be collected and smelted into ingots. Very often the collected parts are too big or too heavy for transportation or smelting, so it is necessary to cut them into smaller and lighter parts. One of the most efficient ways for cutting copper, bronze, zinc, aluminium or steel is with diamond wire. Tyrolit is one of the leading partners Below copper cutting in Middle East.

for large foundries worldwide and has successfully completed a number of projects.

Cutting copper in the Middle East Union Copper Rod is an Abu Dhabi based manufacturer of copper rods for the cable industry. Whenever there is an emergency stop of a furnace the remaining melted copper will be collected and cast into moulds. These ingots are 1x1m and weigh 2-3 t and too big for re-using in the melting process. In total 35 ingots were cut into smaller elements. A Tyrolit Hydrostress 25kW power pack PPH25*** and a TYROLIT steel wire DWM***-S mounted on a SK-SD wire saw were used. A cut of approximately 1m3 could be done in 10 hours and produced nearly 40kg of copper chips, which were collected and reused.

Deep cuts welcomed

Cutting bronze in Sweden A similar application was performed by the Swedish drilling and sawing contractor Haga Rot AB. Some 400mm thick and 2x1m big bronze ingots had to be cut for one of their customers. The blocks had been cut with a Tyrolit Hydrostress electric wire saw SK-B WX15 and a TYROLIT steel wire DWM***-S. A cut of 1m3 could be done in approximately 2.5 hours.

Deep cuts maybe a phrase linked to UK government spending, but for a drilling and sawing company based in Coventry, it takes on a whole new meaning. Skilled operatives from D-Drill have been called in to a cardboard processing plant in Monmouth to cut out a series of channels to allow rolls of cardboard to be processed. D-Drill has been contracted by building company Thackway and Cadwallader to undertake the work, which will see 13 bases cut out over a series of three-day visits for each.

The company will use a specialist floor saw with a one metre diameter blade to cut down to depths of 600mm. “It is very rare for us to have to use this machine, it maybe happens a few times a year,” said D-Drill representative Chris Eaton. “These are very deep channels that we are going to be cutting and you have to be a highly trained diamond driller to operate this machine and also need a great deal of experience. We are delighted our experience and expertise have helped us to secure this contract.”

AGE OF SMART SAWS In this digital age we expect every device we buy to be smart. Who wants a washing machine devoid of smart functions or a less-than-smart phone? The concrete sawing industry has quickly picked up on the trend and is smartening up by the day. PDi presents an overview of available smart HF systems.

PDi’s annual and special feature on new concrete cutting wall and wire saws.

Husqvarna: wireless intelligence Husqvarna keeps on enlarging its range of electric wall saws. The latest addition is the WS 482 HF, which is built around the same technology as its predecessor WS 440 HF, but can accommodate bigger blades up to 1600 mm. The saw has a two-speed gearbox with variable speed transmission that allows the operator to choose the optimum speed, depending on the blade type and diameter and the material to be cut. “The WS 482 is incredibly powerful,” says Husqvarna Construction Equipment Product Manager Lars Gustafsson. “It delivers 19 kW to the blade shaft with a 32 A fuse, despite the saw weighing only 28 kg. Its great advantage is that if only 16 A are available onsite, the WS 482 can still deliver a power of 9 kW.” The machine has modular construction for fast and easy set-up and dismantling. Another important feature is a wireless remote control, which has ergonomic design with a large colour display showing the saw performance. Its menu features include load indicator, rpm, run time, calibration and stopwatch.

Shooting for the moon with Titan Austria-based Braun, one of the world’s leaders in HF technologies, has launched a new wall sawing system called Titan that, according to the manufacturer, breaks new ground in this field. Titan is built of hightech materials used in the aerospace industry and due to this the system is extremely lightweight and robust at the same time. It has a carefully designed modular construction that allows for easy operation and maintenance. The machine is driven by a low-speed motor of maximum 6,000 rpm that results in a higher motor life, higher operational safety and lower maintenance costs. Thanks to the motor’s high torque, the saw shows excellent performance even with blades of up to 2,000 mm in diameter. Should the system fail, Braun engineers can log in to the Titan control unit using the mobile communication protocol to detect the cause of the failure. The same method can be used to update its software. The Titan is fully compatible with the most widely used track systems, such as Hilti, Tyrolit and Hydrostress. And like any other Braun wall saw, it can be switched to wire or circular sawing mode by using the appropriate add ons. For more information, contact Siegfried Ubleis at s.ubleis@braun.at

control. Tractive was initially reluctant to introduce this feature because of safety issues. If there is even a remote risk of the centre bolt touching some object like an adjacent wall, it can result in loosening the bolt and flange. In that case, reversible spindle rotation might be dangerous. However, having done some extensive testing, the manufacturer came to the conclusion that this feature offers a satisfactory safety margin. Nonetheless, Tractive warns any operator who wishes to use it that the equipment, especially blade flanges and parts in the quick disconnect spindle, should be cleaned and serviced properly and that the right torque setting should be used to tighten the blade flange bolt.

Two new Lavina grinders US manufacturer Superabrasive Inc has recently introduced two new machines for concrete floor preparation and polishing. The first introduction took place in the US but production is set for delivery worldwide.

Superabrasive Inc with head office in USA and production facilities in the US and Europe has strengthen its position on both sides of the Atlantic. Now the US manufacturer is launching two new models, the Lavina 21 and propane driven Lavina 30G Pro.

The Lavina 21 In the US Superabrasive, Inc. has released a new Lavina 21 inch (533 mm) machine, and the perfect starter for small projects with a small budget. At 3.5HP and 90kg, it is easy to manoeuvre and transport. It is also available in 1.5HP, 110V version. Lavina 21 features a new 200 mm head and each machine comes with three 200 mm quick change plates and three 200 mm foam plates. As with all Lavina machines, it may be used wet or dry, and should be accompanied by Superabrasive’s standard line of recommended tooling. “Lavina 21 is very simple and easy to operate. Just on and off. No inverter to mess with. With the aggressive price point creating such a low initial investment it makes this machine extremely popular,” says Superabrasive sales manager Len Sniegowski. “Plus it’s a Lavina. We haven’t led the way as the low price leader for any of our products, but this equipment fills a very large niche market for all of our

worldwide distribution. Lavina 21 is the perfect solution for rental stores and home owners.” The new Lavina 21 machines are available through Superabrasive’s extensive network of distributors and dealers worldwide.

The Lavina 30G Pro propane machine In the US Superabrasive, Inc. has released the first propane driven Lavina 30G Pro 762 mm all in one planetary grinding, polishing and burnishing machine. It was primarily designed for big box store concrete polishing projects where a high-speed, large area concrete polishing solution is needed. The machine is driven by a Kawasaki 18 HP gas engine with a patented Onyx Solutions propane conversion and eliminates the need for generators and cables. Lavina 30G Pro features three 343 mm heads for a 762 mm working area and can be used for both wet and dry applications. The 30G Pro is also among Superabrasive’s new line of low profile Machines where it can reach underneath shelving, cabinets, and other hard to reach places. This gives a distinct advantage of working underneath racking and shelves and allows for less edging. “The machine went through 800 hours of continuous testing over a two month period only stopping to change propane tanks and diamond tooling so we are 100% convinced that this machine will surpass our customers’ expectations of quality and value,” says Superabrasive sales manager Len Sniegowski. “Not only will this machine grind and polish like a traditional Lavina machine, it proThe Lavina 21.

New and patented cold saw for metal cutting from Braun Braun Maschinenfabrik in Austria is showing the first pictures of their newly developed and patented mobile cold saw for cutting steel structures. This saw is in particular perfect for sawing application and dismantling in for instance nuclear power plants. The Braun cold cutting saw can be used with and without cooling fluids and is usable under water as well. This mobile saw can be fixed to the structure its cutting by using magnet feeds, tension belts, hydraulic or pneumatic clamping devices or screws. The saw can be used in hostile environments like contaminated areas of nuclear or chemical

industries or under water. The saw can be remotely controlled by using cameras or sensors. The maximum cutting depth in steel, as well as stainless steel and high alloyed steel, is 520 mm. Even though lower tool costs the cutting performance of the new Braun cold saw is in steel approximately 8 times higher as the cutting performance of a diamond wire saw. The control of the saw is free programmable (SPS) and suitable for fully automatic action, pre-programmed operating sequences.

Just one Lavina 30G Pro is capable of completing 140m2/h, start to finish, using the big box store system. Unlike other propane machines this machine actually does go very easily underneath racking and cabinets to virtually eliminate the need for edge work. If contractors need to do heavy grinding or coatings removal, Lavina 30G Pro will obliterate any other propane machine for productivity. This thing is the real deal.”

Dr. Fritsch launches new laser welding machine for drill bits batch size of 1.3 up to 2.2. Due to that, the set-up times were often longer than the net welding times. In general, the only requirement for changing the diameter is to deposit the new segments. As a consequence, the company estimates the BSM 300 is a machine that supports the customeroriented production process in an ideal way. The products of the company specializing in machines and solutions for the diamond tool industry for over half a century now, are characterized by consistent high quality standards.

www.dr-fritsch.de

With about 150 laser welding systems on the market, Dr. Fritsch is taking an exceptional position in the diamond tool industry. This year, the company is introducing the new BSM 300. A new centric clamping system has been developed for this machine. Core drills with a diameter of 8 mm up to 300 mm can be clamped without changing the fixtures. This leads to a unique flexibility with drastically reduced set-up times. Thanks to flying optics on three axes, the diamond segments can be welded fast and directly on the core. So the net cycle time is only half as long as with the previous generation of drill bit welding machines. With a new measuring system the welding position is measured two-dimensionally and then corrected prior to each welding process. This permits, on the one hand, an automatic segment side clearance control and the adjustment of tolerances in roundness. On the other hand, there is an automatic axial run out correction. Due to that, it is possible to guarantee a high and constant welding quality, which means higher production security. As a side effect, there is a lower requirement concerning the tolerances of the core and as a consequence, cheaper cores can be used. Extensive tests have resulted in a strongly improved welding strength and, particularly, very constant break-off values. Optionally, the BSM 300 can be automated in the future. However, in that case a magazine for cores is necessary.

The option of welding rings is also available Although the net welding time is just half as long as with the previous BSM machine, the productivity of the machine is much higher. Since batches are often very small, a reduction of the setup time is of high significance. Statistics based on measurements at professional core drill manufacturers have shown an average

They PDi takes a look at new solutions for efficient dust extraction and air cleaning. Dealing with dust on sites is becoming a bigger and bigger issue, triggered by health conditions and even deaths among construction workers. This situation has resulted in stronger environmental regulation all over the world, particularly in Europe and USA. Some countries have their own regulations that are even stricter then those set out by, for instance, the European Union, which has the strictest environmental legislation in the world, or the Environmental Protection Agency in the US. PDi looks at some of the new equipment for dust extraction and air cleaning.

The growth of the water mist cannons During recent years there has been a growing number of suppliers of dust extraction equipment for the construction industry and especially the comparatively new method of using water mist to bind dust particles in the air. Demolition and recycling contractors all over the world now frequently use water cannons and the biggest number of manufacturers is found in Italy. The idea originally came from the US manufacturer Dust Control Technology several years ago. Water cannons to prevent dust and odour are now used in many types of industries, including demolition and recycling. Depending on the type of water cannon a large area can be covered for dampening the dust, improving the working environment, improving the site and also reducing the impact on worksite neighbours. Water mist is limited in its use as it can only really be used in areas where there is no equipment sensitive to water. Indoors and in sensitive areas contractors need to fall back on traditional dust extraction and air cleaning equipment.

Put Australia, New Zealand, Japan, Europe & Russia. “The national rules for dust suppression are becoming more restricted with the direct consequence of a stronger demand for efficient dust suppression systems. Growth of the Dust Fighters is proceeding year by year and it’s just the beginning and new marketing opportunities are coming every day,” says a DF Ecology spokesman.

New smart features from Duztech A comparatively new manufacturer of dust suppression systems is the Swedish company Duztech. During 2011 Duztech has presented several new products, including a silenced version for demolition and dust extraction in sensitive inner city environments. A new and more compact remote control, as well as a new type of main water valve that reduces the water consumption, has also been developed. Duztech has also launched its new MultiTasking-System. This has been developed for contractors using the same range of machinery for different tasks. MTS can adjust the water flow and has been a big success in applications where the amount of dust varies extensively during short time periods. The new model D800, with an extensive reach, has shown to be very successful in windy conditions. “This is really a smooth machine. It is rather small and compact with a massive capacity to a beneficial price,” says Duztech marketing manager Magnus Engström. Duztech also have smaller machines in the range like the D300 and Mosquito, for small and confined areas. The D300 can be connected to a 16A 400V AC outlet and Mosquito to a normal 230V outlet. Mosquito can easily be moved by hand. During the autumn of 2011 several new variations of

Fighting the dust with DF Ecology Italian manufacturer DF Ecology claim to have the biggest range of dust suppression equipment. They are robust and easy use and the Dust Fighter range is already in the rental fleet of the most important rental companies. The Dust Fighter range can be considered as low consumption machines. The big water and energy saving of DF permit end users to obtain the right mix with a high performing machine. All DF’s can be equipped with remote control and automatic rotation system. DF is available in North and South America, Canada,

Mosquito will be launched, such as dust suppression for handling garbage and coal.

Dust suppression systems for complex applications More complex dust suppression systems from Italian Idrobase Group are composed of four companies each of them specialized in a niche water pressure market. One product line is the Idrotech industrial fogging and dust suppression system, which is used in the construction industry. Idrotech is now involved in a complex project delivering a

PDi • Issue 3 • July - Aug 2011

Dampe dust suppression system for the exploratory tunnel for the production of the Brenner Base Tunnel in South Tyrol. At 55 km the Brenner tunnel will be the longest railway tunnel in the world and will go from Innsbruck to Bolzano, Italy. Work began in April 2011 and should be completed by 2020. Excavation works, located approximately 1,500 m deeper than the exploratory tunnel for a length of 10,450 m have produced so much dust to make work extremely difficult and dangerous. The system supplied by Idrotech was designed by dividing the areas to be treated by the fogging system in several sectors, grouped into two macroareas and served by two distinct fogging lines. The first line has been used for dust suppression during the excavation works and transport of materials, while the second line has had the dual task of dust suppression under the conveyor belt as well as to suppress dust suspended in the air.

TechnoAlpin Pro Air Solutions presents V7 Another Italian company, TechnoAlpin Pro Air Solutions, makes mobile and stationary solutions for dust emission control in demolition work, open-pit mining, recycling plants and industrial applications. TechnoAlpin dust controllers work differently to other brands, as they generate a fine atomized mist. Far less water is used in the process, thus preventing the formation of muddy puddles. TechnoAlpin products are also used in open-pit mining and at recycling plants. Now TechnoAlpin has added the fully automated dust controller V7. The V7 is a universal, powerful and environmentally friendly solution. Special nozzles with ceramic inserts produce a fine water spray, which effectively lays the dust particles directly at the source. The latest valve technology and an optional second nozzle ring guarantee efficient water flow. The highperformance fan, with a 52° angle of inclination and a 360° rotation angle ensure a maximum operating range. TechnoAlpin is based in Bolzano, Italy and has been in the business of machine installations and systems engineering for 20 years. The expertise which has evolved, which has generated several patents in nozzle construction, turbine design and

ers

automation technology, is invested in the dust-bonding solutions developed by the pro air solutions division.

WLP with three versatile models WLP S.r.l., another Italian manufacturer, was founded in 2005 with the aim of planning, constructing and selling dust suppression and odour control systems for a wide range of industries, including construction, demolition and recycling sites. The current range consists of three models that can be supplied in mobile or standing versions, and equipped with electric rotation and rising timer to pause and work, electric three way valves with auto discharge, water pump and remote control: • • •

WLP410: Throw theoretical distance: 20-30 m Rings of nozzles: N. 2 Number of nozzles: 64 (n.32 for ring) Nominal fan power: 3 kW WLP500: Throw theoretical distance: 40-50 m Rings of nozzles: N. 2 Number of nozzles: N. 72 (N.36 for ring) Nominal fan power: 5,5 kW WLP700: Throw theoretical distance: 60-70 m Rings of nozzles: N. 3 Number of nozzles: N. 150 (N.50 for ring) Nominal fan power: 11 kW

“Dustcontrol captures dust at source” Inside is an environment where water mist dust suppression systems normally do not work. In these situations demolition, concrete cutters and concrete floor renovation contractors must rely on vacuums and air cleaners. One of the big manufacturers is Dustcontrol with their slogan ‘Capture dust at source.’ Dustcontrol is known for their different types of suction casing. Removing unwanted material at source before it affects the production efficiency or causes health problems is exactly the right thing to do. Equipping all tools with suction casings and connecting them to efficient dust extractors can reduce dust concentrations considerably. Dustcontrol has a wide range of suction casings and rubber

boots to make sure dust is captured before it is released into the air. Vacuuming with a dust extractor, equipped with HEPA H13 filters with a filtration of particles 0.15-0.3 m2 to 99.95%, will improve the cleaning operation. Dustcontrol’s dust extractor DC 2900c is designed for source extraction and vacuum cleaning. The filter cleaning of the unit is done with a reverse pulse, which gives the filter a long action life. DC 3800 Turbo EX is the dust extractor for continuous operation in ATEX zone 22. It is a medium sized dust extractor with a high cyclone and a three-phase turbo motor.

Dust

It is available certified to IP65 standard conductive dust. The DC 3800 Turbo EX conforms to all the regulations for ATEX and explosion resistance and is certified for it by IFA, SP and Intertek Semco. In addition it is S marked. Finally the DC 5900 Semi Mobile System can be docked to a temporary fixed pipe system and used on large areas. It is especially suited to managing large volumes of concrete dust. Also there are new air cleaning machines DC AirCube 500 and DC AirCube 2000 from Dustcontrol and are primarily sold to renovation companies. The machines are fitted with a HEPA H13 filter, which removes 99.95% of particles and are suitable for the separation of fine and dangerous dust to a minimum size of 0.3 microns. Dustcontrol air cleaning machines work without water.

Ruwac USA Introduces Propane Powered Vacuum Ruwac USA has announced the DuoVac 220-S to its Red Line series of portable vacuum. The DuoVac takes the vacuum filtration and capacity of the 220 V Red Raider and multiplies it by two. It is the perfect unit for jobs that require a portable vacuum capable of handling large clean-ups or the point of source extraction of materials such as dry concrete and cement dust. Ideal for multiple users, the 220-S includes a quick disconnect cart that transforms the DuoVac into two separate units. It is earthed to protect against static build-up and made from a durable compression cast housing that is rust-proof, dent-free and guaranteed for life. The DuoVac 220-S’s unique foot-actuated drop down dustpan and filter shaker system will not only make cleaning hassle-free, but also add life to the vacuum system. A simple shake, step, pull and empty will result in a dustfree clean up alongside prolonged filter life and improved vacuum performance. This vacuum is also equipped with an oversized, MicroClean filter that is 99.9% efficient at .5 micron for longer vacuum cycles and less filter maintenance. For applications that require absolute filtration, an optional DOP tested and certified HEPA module, 99.9% efficient at .3 micron, is available. Another new product from Ruwac USA is the latest improvements to its line of High Efficiency Cyclone pre-separation systems with a new Direct Bagging System. This pre-separation system comes with all the benefits and features of the HEC, but with a universal bagging system that allows a safe, dust-free clean up. This minimizes any contact with its contents, keeping workers safe from harmful materials. Unlike other bagging systems, the HEC-DB is universally compatible with almost any type of bagging container, eliminating the need

to purchase expensive, specialized bags. Among the innovative improvements made to the HEC-DB is an external gravity drop system. This unique gravity drop holds the separator’s contents as the bag is emptied or changed, and will also allow discharge of the contents at the pull of a lever. The HEC-DB’s new bag clasps will hold bags in place and also provide an easy release. Ruwac’s external gravity drop system, combined with the HEC’s specially engineered ability to separate dust and debris, increases the vacuum’s collection capacity and filter life, reducing costs and maintenance time. The High Efficiency Cyclone removes 97% of fine dust and debris from the airstream before it hits the filter. It is a benefit not found in most other separation systems, as materials entering the vacuum will not clog the filtration system.

Completely new range from Klindex The Italian manufacturer Klindex has introduced a new line of dust extractors called Supervak Automatic Self Cleaning, designed to handle huge quantity of dust powders without the filter blinding. Thanks to the patented self-cleaning triple filters the new vacuums allow operators to continuously vacuum the finest powder without filter trouble. Supervak dust collectors are the only vacuum that cleans automatically the filter thanks to the patented system of vibration and contra flowing. Supervak ASC is the ideal machine to vacuum a huge quantity of fine dust without having to change the filter continuously. An electronic timer that regulates the time of filter cleaning filter and allows vacuuming fine dust like cement, flour, sawdust and ceramic dust without stopping to clean filters. The Supervak Self Cleaning series are the economy version. The only difference is that the operator, instead of the electronic timer, chooses when to clean the filter by turning a lever. KY1 ASC like all Supervak models is equipped with automatic self-cleaning, but it is also the only professional vacuum cleaner with retractable dimensions due to its telescopic frame. Supervak KY3OO, with a 3phase motor, is particularly aimed at industrial applications. Thanks to the automatic self-cleaning filter it can work for many hours without stopping. The vacuum cleaner series KY7O has the same self-cleaning filter concept of the bigger machines with the difference that the operator, instead of timer, chooses when to clean the filter. KY70 has two air filters. Issue 3 • July - Aug 2011 •

Demolition jobs have never been easier Skip the old way - save money The dust suppression market use old fashion low-pressure, electrical charge dust suppression systems. Traditionally low-pressure dust suppression systems are widely used and consume great amount of water, and usually make the work site muddy. Electrical charge dust suppression systems are usually very expensive, space taking and complicated to use. Dust particle binding, compact size and low water consumption are specific features of Dynaset dust suppression systems and can be coupled to a machine without the need of a spraying hose. This provides advantages of saving in labour costs and increased working safety. Using dust suppression on demolition and crushing projects improves efficiency and safety. It makes the air notable clearer, resulting in better visibility and safer breathing. The system can be used effectively in virtually all machine operated work, where dust emission is considerable. The greatest benefits of the dust suppression system are in extra dusty work, such as demolition, mining, crushing or in excavator breaker use. The system is especially designed to equip hydraulic crushers, pulverisers and hammers used on excavator based demolition machines as well as other tools and machines involved in handling dust emitting materials. Basically the water is atomised by high pressure to microscopic water drops. The weight of the water bound dust particle increases dramatically, which makes it fall. However, the size of a water drop is so insignificant, that the dust particle doesn’t become wet enough to make working area muddy. The high-pressure dust suppressions system is based on the powerful Dynaset high-pressure pump, which is powered by the hydraulics of the carrier machine. High-pressured water is sprayed through special nozzles directly to the area to be

treated to kill the dust before it can spread. The system has two settings of continuous spray and power spray. This enables the amount of water used to be adjusted for best suitability for each situation and help save water and decrease filter maintenances cost. The Dynaset dust suppression system also includes a washing pistol for washing the machine after finishing work. The latest innovation is the dust suppression umbrella, which is fitted on top of a mobile machine or on a boom. The umbrella covers dust suppression for a 30 m circular area.

Doosan’s new machines meet Stage IIIB Engine Emission Regulations

Rotary Grinders for Bobcat Loaders and Excavators Bobcat has launched a new range of rotary grinder attachments for its compact loaders and excavators. The new grinders, aimed at a wide range of construction, demolition and utility industry applications, consist of a double drum, driven by an integrated hydraulic motor. The new attachments grind powerfully in concrete, asphalt or rock and also transmit relatively low vibration levels to surrounding structures and produce debris that can be recycled. The new grinding attachments allow precise removal of material, without damaging adjacent structures. They can also be used for less precise work, such as the demolition of walls and other structures, for digging trenches in hard and rocky ground and for preparing asphalt or concrete surfaces for repair. The three models in the range, the RG20, RG40 and RG60, provide a choice of cutting widths and are suitable for use on the larger Bobcat loaders and excavators. The RG20 has a standard cutting width of 565 mm and is for use on Bobcat E32, E35, E45, E50, E55W and

E60 mini-excavators. The RG40 has a standard cutting width of 625 mm and is for use on the E80 excavator and on the Bobcat S205H, S630, S630H, S650, S650H, T190H, T650 and T650H compact loaders. The largest RG60 cuts to a width of 850 mm and can be used on the Bobcat S770H, S850H, T770H, T870H and A770H compact loaders. The use of rotary grinders on Bobcat compact loaders or excavators requires the installation of a special application kit and the same as for mounting Bobcat hydraulic breakers. The rotary grinder attachments can be mounted on Bobcat excavators with Pin-on, Klac or Lehnhoff systems. For Bobcat compact loaders, a Bob-Tach bolt-on frame is used.

150,001 Hitachi mini excavators and counting A landmark has been reached for the production of mini excavators in Japan, as Hitachi Construction Machinery Tierra Co., Ltd. (HCM Tierra) celebrates machine number 150,001 to roll off the production line. The delivery of the ZX52U-3 to Hitachi Construction Machinery (Europe) NV (HCME) was marked with a ceremony on 9 May at the Oosterhout mini excavator factory in the south of The Netherlands. The handover celebration was attended by Masamichi Itou, Divisional General Manager Oosterhout factories, Geert Elsen of Belgium’s official distributor of Hitachi mini excavators, Elsen Traktor, and Bart Godts of construction and demolition company BVBA Godts, which purchased the machine. HCM Tierra began production of Hitachi construction machinery in 1989, with the EX60 and was taken over by Hitachi Construction Machinery Co., Ltd. (HCM) the following year. By 1996, 30,000 units had been manufactured. The company has

nearly 500 employees and owns a number of production sites around Japan. Its head office is in Osaka. “The delivery of unit number 150,001 is a tribute to the great quality of Hitachi mini excavators. I am delighted to be able to present it,” says Masamichi Itou. “We are as proud of our product today as we were when we produced our very first one 20 years ago.” The ZX52U-3 will be the 11th Hitachi machine to join BVBA Godts. The company has been a customer of Elsen Traktor for five years and owns a wide variety of models, including mini, wheeled and medium excavators, and a ZW310 wheel loader. “I am very happy to receive this machine and expect to have a lot of work for it,” says Bart Godts. “It will mainly be used for drainage work and other similar construction jobs. We chose Hitachi machines for their quality and reliability, and the customer service provided by Elsen Traktor is also very important and know we can rely on them 24/7.”

Scheduled for September 2011, the first of a new generation of articulated dump trucks will be unveiled by Doosan Infracore Construction Equipment, beginning a series of product launches, including new excavators and wheel loaders, to meet the requirements of the EU Stage IIIB engine emission regulations. The Stage IIIB regulations, which apply to equipment powered by diesel engines of 75 KW and above, are being introduced in 2011 and 2012. Compared to Stage IIIA, Stage IIIB requires a further reduction of 90% in particulate matter 50% in Nitrogen Oxide. Stage IV will come into effect in 2014 and will reduce NOx by an additional 80%, almost completely eliminating both PM and NOx emissions. As well as in Europe, various measures are being phased in throughout the USA, Canada and Japan. Stage IIIB corresponds approximately to Tier 4 Interim in the US. However, EU Stage IIIB compliance will only be certified for Europe and will not be valid for the US. To meet the Stage IIIB engine emission regulations, Doosan has combined high-pressure common rail fuel injection systems and the company’s electronic control unit with two different emission reduction technologies, exhaust gas recirculation and selective catalytic reduction. Using both technologies, Doosan has applied the best technical solution for each product category, with the choice depending on the engine’s characteristics, as well as the application to ensure that each machine delivers the best performance and lowest operating costs.

The EGR technology is more suited to on-site machines where the requirement is for multi-task capabilities and has therefore been chosen for the new Doosan wheel loaders below 130 kW and for all the new Doosan wheeled and crawler excavators. These products are using the EGR technology associated with the Doosan and Isuzu engine ranges. Particularly suited for machines requiring high torque or speed, the SCR technology is being used on the new Doosan ADTs and wheel loaders above 175 HP, all of which are powered by Scania engines.

After-treatment Technologies EGR or SCR engines are not enough on their own to reduce emissions to Stage IIIB levels. As a result, Doosan has combined the engines with a selection of after-treatment measures. These include catalytic oxidation, filtering, regeneration and AdBlue®. These measures are already widely used by car manufacturers. They clean the exhaust produced by the engine or convert it into water, nitrogen and carbon dioxide. The most suitable after-treatment system depends on the engine and Doosan has tailored this to match the EGR and SCR systems in the company’s machines.

Atlas Copco’s new CC4700 CombiCutter The new CC 4700 demolition cutter for 45-65t carrier units completes Atlas Copco’s range. Stability, reliability and low operating costs are the key criteria for the development of this crusher model. “With D demolithe CC 4700 we are responding to the trend towards Glarger ÄN line manager r ie n Lproduct tion equipment,” says Silent D Demolition Tools T -se S A ya Wolfgang Hohn. “And weNare E closing N Kthe gap that existed between our S G which was presented at Bauma 2010.” CC 3300 and the CC LÄ6000, VER follows the design of the entire hydraulic demolition TheÖ CC 4700 cutter range of Atlas Copco. The system of two articulated arms and two lifting cylinders has been tried and tested and it offers a constant high crushing force throughout the entire closing process. And the combination of one single and one twin blade arm enables maximum stability even under extreme loads. Universal arms and Steel cutting arms versions are available for the CC 4700. The crusher arms are stably mounted on a central main pin, reducing the time required for changing crusher arms by up to 75%, compared to separate mountings. Both crusher arms can be fitted and removed as a unit, because the coupling and positioning system, continues to link the two together even after removal. Crusher arms can be changed on site, thereby avoiding timeconsuming and costly transport to the workshop. And the practical concept for wearing parts also saves time. Crusher teeth and cutting blades can be turned or changed quickly and easily on site. “We found that about two-thirds of the operating cost of an attachment arise from factors such as energy, operator costs, service and maintenance, and only one-third from the investment costs,” adds Wolfgang Hohn. “With the CC 4700 we are focusing on these consequential costs.” Technical data CC 4700 U* CC 4700 S* Carrier weight class, t 45-65 45-65 Operating weight, kg 4,750 4,500 Cutting force, t 198 Crushing force, front crusher teeth, t 155 Oil flow, l/min 350-450 350-450 Operating pressure, bar 350 350 Jaw width, mm 1300 710 Jaw depth, mm 1080 860 *Jaw version “U” = Universal jaw, “S” = Steel cutting jaw

New M Co

i x a M r o t c i v u f i d t y o r s i P t in for m

All major manufacturers of mini excavators and loaders have extended or upgraded their product lines recently. Operator comfort and safety, higher productivity and enhanced mobility in limited access areas are the key features of the new generation machines.

MINI EXCAVATORS

Mini excavators, being a perfect tool for various tasks in confined areas, remain an important market for manufacturers. So what are the trends in the sector? Most companies seem to be looking into ways to make their machines even more nimble and agile. Reducing or eliminating tail swing is one of the solutions they offer. Also, the new generation minis are becoming increasingly geared towards the needs of rental companies that demand versatility and high performance from the equipment.

“Hitachi works its tail off” Hitachi Construction Machinery (Europe) has long prioritized the market of mini excavators with short or zero tail swing. The first machine, the ZX30U-2 hit the European market back in 2005 and proved a valuable addition to the existing Hitachi range. Since then, Hitachi has updated its line of compact machines several times. The ZX10U-2, ZX17U-2 and ZX22U-2, first unveiled at Bauma 2010, continued the ZAXIS series. These were followed by another three short-tail models ZX29U-3, ZX33U-3 and ZX38U-3. Although mini excavators have long proved their worth for such applications, the machines with zero tail swing took the idea of mobility to a new level. The new minis are available in both cab and canopy versions. They are driven by three-cylinder engines, which comply with Environmental Emission Regulations EU Stage III A. Also, the excavators boast the Eco Zone technology, which helps reduce fuel consumption while maintaining a high level of productivity. HCME Compact Line Product Manager Joep van den Maagdenberg, is confident that the introduction of these new models will allow Hitachi to further consolidate its position in this segment.

ARTICULATED LOADERS

Articulated loaders are often viewed as a viable alternative to conventional skid steers. No skidding of tyres to wear them out, lower fuel consumption thanks to hydrostatic drive and simplicity of driving and operation, are just a few benefits of an articulated loader. In some industries articulated loaders are becoming increasingly popular.

Schaffer creates skid steer substitute loaders The German manufacturer Schaffer specializes in machines for work in recycling plants and aluminium smelters. The Schaffer range, of what the company has dubbed skid steer substitute loaders, begins at 26 hp and goes up to 130 hp. Every machine, except for the smallest, has a 30mm plate steel mast and oversized axles. Extra guarding is available for work at waste facilities to protect drive shafts and brake lines. All loaders boast the Schaffer oscillating articulation joint. The oscillating joint has two advantages as it aids traction by allowing all wheels to stay on the ground in rough terrain and improves operator comfort acting like a suspension system. The machines are powered by Kubota water-cooled diesels. For further information contact Cameron Moir at cmoir@schaffer-loaders.com.au

Avant Tecno launches a LPG model Finland-based Avant Tecno has added the Avant 525LPG to its range of articulated loaders. What singles out this machine of the rest of the range is a 23 hp liquefied petroleum gas engine. The other seven models are powered by regular 20-49 hp diesel engines. The Avant 525LPG is ideal for demolition, refurbishing and other indoor jobs that call for a compact, yet powerful machine, or where the use of diesel or petrol engines is banned. The combination of the Avant 525LPG and a hydraulic breaker, for instance, is very efficient for indoor demolition works. The machine features the Avant proven hydraulic system of hydrostatic drive with a hydraulically pilot operated variable displacement pump in the drive circuit, and a twin-gear pump for auxiliary hydraulics. A Kubota 23 hp, three-cylinder, water-cooled LPG engine is mounted on the Avant 520 chassis, with the gas bottle positioned in the rear, on top of the engine. The gas bottle mounting bracket is foldable to provide access for maintenance. For further information contact Olli Kurki at olli.kurki@avanttecno.com

European Compact Avant Tecno Oy’s innovations have taken the company along a road of growth and international success. This Finnish company claims to be the leading European manufacturer of compact wheeled loaders and sales have been made as far away as North America and Australia. With lift capacities ranging from 350 to 1,400 kg, the multi purpose Avant loaders are being used especially in landscaping, construction, agriculture and property maintenance. The versatile Avant is easy to transport from site to site and has proved to be an efficient tool, for example on building sites with little room to manoeuvre. In addition, the LPG engine on the Avant 525LPG makes it possible to handle indoor demolition jobs with hydraulic breaker attachment and then take the debris away with a bucket mounted on the loader. The articulated Avant loader is also an ideal machine for landscaping. With over 100 different attachments to suit a multitude of jobs the Avant is a real multi task machine.

Wide range of attachments Sound expertise in machinery production is at the heart of Avant Tecno’s operations. The trump cards are Avant’s experience in research and development, innovation and understanding customers’ needs. Continuous product development is a key factor. Proof of this is the three new series launched in the last four years and the 100 different attachments designed for Avant loaders. New products are being developed all the time, based on customer needs.

Made in Finland Avant loaders are manufactured in Ylojarvi, next to the city of Tampere. The company has subsidiaries in Germany and the UK, and exports to most European countries, North America, Australia, New Zealand and South Africa. Avant Tecno’s expertise in machinery construction is also put to good use by its sister company Leguan Lifts Oy, also in Ylojarvi, which uses Avant Tecno skid steer loader chassis as the undercarriage for its Leguan self propelled aerial work platforms.

Cleanaway switches to Schaffer articulated loaders In Australia waste industry leader Transpacific Cleanaway has made the switch from skid steers to German articulated loaders at three of its recycling plants and believes that articulated loaders are the future of the industry. Rod Stone is site manager at Cleanaway’s Moorebank recycling plant in New South Wales, one of three recycling sites in Sydney, Melbourne and Brisbane, where Cleanaway operates Schaffer 5050Z articulated loaders. “I was here when we first built this place two years ago,” says Rod Stone. “First we were using a skid steer to do the work, but we knew as we grew we would need something more efficient. On looking around we came across the Schaffer loader, and our Brisbane management team purchased three of them. It seemed like a good thing and we went with it, and it’s been a good loader ever since.” The 50hp Schaffer loader is used in the processing of recycling various materials, such as cardboard, paper, polystyrene and plastic at the Moorebank site. Cleanaway collects the raw materials through a harvest programme at industrial and municipal sites. Recyclable material is sourced

in one bin then sorted into different categories back at the recycling depot using the Schaffer loader with a 4-in-1 bucket. The loader is also used to sift out non-recyclable material. After that, the articulated loader feeds each type of material in separate batches onto a conveyor, which presses out homogenous bales in a baling machine. The bales are transported off site to be made into recycled products by various manufacturers in Australia and overseas. Cameron Moir, general manager of Schaffer in Australia, said the German articulated loaders were particularly suited to the recycling work because they have the highest articulation angle of any articulated loader on the market. “Front end loaders have traditionally not been the machine of choice in the waste industry because they were previously not so manoeuvrable,” says Cameron Moir. “But the Schaffer articulated loaders from Germany, because of the articulation angle, are much more nimble and work well in recycling plants like Cleanaway’s. They offer great visibility and reach. They also feature ergonomically designed seats with inbuilt suspension, which means

PDi • Issue 3 • July - Aug 2011

a very comfortable ride for the driver.” Cleanaway’s Rod Stone says the Schaffer has run smoothly with only routine maintenance for over two years. Another cost saving has been the decision to change to solid fill tyres. “We decided to convert to solid fill when we were getting too many punctures running over all the recycled material and it’s saved a lot of money doing it that way,” says Cameron Stone. “I think this type of articulated machine will definitely be a trend in the recycling industry and it has helped us build our growing business.”

Improving Mobility in Bucharest In Romania the Basarab Bridge, which takes its name from the nearby metro station, is designed to improve the flow of traffic in the North-West of Bucharest and was opened for road traffic on 19 June 2011. The Basarab Bridge is 1.9 km long and links Titulescu Boulevard to the Grozavesti district. The bridge will carry road and tramway traffic over several important boulevards and the rail tracks of North Station. A station will be built above the tracks to provide connections with tramway, train and metro, lifts and escalators giving direct access to the platforms. The Avis Instal Company was selected to cut out the two concrete openings for the elevators in the ceiling of the metro station. The ceiling is a 700mm thick reinforced concrete slab. The job consisted of cutting out one opening of 7.7 x 6.4 m and another of 6.5 x 4.3 m. This complex job required to combine different concrete cutting techniques and to use both wire saw and wall saw cutting. The wall saw cutting at 700mm depth was initiated with VXC20 disc of 800 mm in diameter and continued with a series of MXC10 blades of 1,200 mm, 1,500 mm and 1,800 mm. The slab was cut into pieces of 2.2 m x 1 m, with an approximate weight of 4 t. The wire saw was used for the smaller cuts using Carbodiam ’s concrete diamond wire type Cobrator CBC10540-2.

New core drills and blades from Heger The specialist drilling and sawing manufacturer Heger, has announced new HeroX Heco drills and the Xflow W5 wall-sawing blade.

The major part of the new drill range is now available in the HECO version. Heger avoids the use of cobalt, as cobalt powders are hazardous when inhaled and can cause serious lung diseases. The HeroX C5 and HeroX C7 cover a huge application area. Where the C5 focuses on good performance in average concrete, the C7 covers more abrasive concrete and both work on reinforcement. All common sizes are available as finished laser welded drills or as segments for brazing.

Late summer release The range is expected to be complete by late summer with C3 and C4 and C9. The C3 will cover extreme reinforcement. The C4 will do the same with huge and hard aggregates like river gravel and granite. To complete the application on the other end of the scale the C9 will be a hard bond for very abrasive material such as asphalt. Heger will introduce late summer the new wall sawing blade in patented Xflow technology. The new cobalt free bond system and diamond result in perfect wear behaviour to achieve easy cutting and efficient life. The Xflow W5 blade is specially designed for electrical and hydraulic wall sawing machines from 15 to 25kW, such as the new Demco Captor electrical wall-sawing machine. Extensive market tests have shown that it is doing its job very well on all common wall-sawing machines in that power range. Long lasting experience and recent tests have shown that Heger technology is outper forming the arranged diamond technology in many occasions. The patented dots of the Xflow technology reduce side friction by 65% to have all available machine power for cutting. Improved wear behaviour of the diamond bond, in combination with high performance diamond crystals, is leading to the performance expected by sawing contractors. On a 800mm diameter wall sawing blade there is an average of about 14 diamond crystals/cm 2 segment surface. If the blade is running at the recommended speed of 900rpm or 40m/s, this means that any section of the material will face 20,000 diamond crystals passing per second. The Heger philosophy

PDi â&#x20AC;˘ Issue 3 â&#x20AC;˘ July - Aug 2011

is built on modern and innovative metal bond systems with optimum wear and lubrication behaviour in combination with excellent diamond crystals. Together with state of the art segment design Heger can reach the performance that contractors need to work fast and efficiently for a satisfactory commercial business result. The new dry cutting range Heger Titan Xtra-Dry also follows the HECO rules to avoid cobalt. The Heger line is designed for hard material, heavy reinforcement and other tough applications. It is available from D115 until D400 for angle grinders, motor and table saws.

General Equipment Company’s new QR Codes In the US General Equipment Company now includes QR codes on its products. When scanned with a smart phone, the codes direct users to videos, literature, operational tips, service information and manuals. They are printed on weather and damage resistant data plates, which are mounted on each piece of equipment. The QR codes were implemented to help rental operators and end users find relevant information quickly and easily. Unlike similar systems in the industry, General Equipment’s QR codes link to product specific websites, rather than a generic page. This eliminates the need to browse for desired information after reaching the site. “Our new system takes people straight to the information they need,” said General Equipment Company president Dennis Von Ruden. “They no longer need to waste time searching the Internet for information or looking for their owner’s manuals. As long as people have access to the equipment and a smart phone, they can

find everything they need.” General Equipment Company’s surface preparation, hole digging and ventilation equipment all include the new QR codes. To take advantage of them, the user must have a smart phone with a standard QR code scanner application installed. This simple application is commonly used and is a free download for many devices.

More efficient deployment of external vibrators Wacker Neuson’s FUE 6 frequency inverter is now available with four connection points instead of the previous three, enabling operators to run external vibrators more efficiently. “The new FUE 6 can be used to run four external vibrators at the same time, making it more efficient, flexible and costeffective than other models,” says Wacker Neuson Concrete Technology Product Manager Markus Martin. As external vibrators use considerably less electrical power than internal vibrators, the fourth connection point enables contractors to utilize more of the inverter’s power for external vibrators than was previously possible with three connections.

Globram hydraulic breakers used in heavy-duty application In 2010, hydraulic equipment expert EuroramRockmaster BV was approached by Hencon Mobile Equipment BV, which at the time was working on the development of a crust breaker, and needed a supplier of a hydraulic breaker suitable to the specific needs of their project. As a worldwide supplier of custom made mobile equipment for the heavy industries, Hencon BV specialises in the development of solutions for situations where conventional vehicles cannot operate satisfactory. For this particular project the crust breaker, used for breaking slag on liquid aluminium, was to be fitted with a hydraulic hammer that can perform under extreme circumstances. Based on the technical requirements supplied, Euroram Rockmaster BV set to work on the modification of its Globram RM45 breaker. Changes were made to its hydraulic and mechanical properties to guarantee optimum performance in this specific, tough application. With both companies satisfied with the outcome of the project, several more modified breakers have been delivered over the past six months. Following this first successful project, the two Dutch companies are continuing their cooperation in new projects. Both are confident the cooperation will expand into the future, and will allow both Hencon Mobile Equipment and Euroram Rockmaster to maximise their flexibility and improve their respective product ranges.

Diagrip fully i Husqvarna launched Diagrip technology three years ago and now the company uses the new technology in a complete range of diamond tools. The success continues by finding new applications where only Diagrip tools can do the difficult jobs. PDi’s Mikael Karlsson reports.

Diagrip technology is mainly concerned with an optimal, three-dimensional distribution and better retention of coarse diamonds in a new, in-house developed segment design that significantly increases cutting speed and lifetime of the tools.

In all high-end diamond tools The company now applies the Diagrip technology in all its range of high-end cutting, sawing and drilling tools, such as diamond blades for wall saws and floor saws, diamond rings, diamond drill bits and wires. “Our increase in sales were double digit the first months after the launch in 2008. This despite the sharp financial crisis in the world that also hit the construction and demolition industries,” says Husqvarna Construction Products Diamond Tools Vice President, Michel Hubermont based in Ath, Belgium. “One reason is that many users have discovered the big advantage of cutting, sawing and drilling at a higher speed, at least 20-30% higher speed and even more, combined with a longer lifetime of the tool that maintains a uniform capacity through the whole working life. Another reason is that with Diagrip it is possible to cut faster, smoother and more even in heavily reinforced concrete, also in steel. So we have found new applications for our tools, like underwater cutting on oil platforms and reformation of nuclear plants, where cutting and sawing must be fast, safe and with no risk of failure.”

The secrets of a perfect mix The research and development manager of Husqvarna

PDi • Issue 3 • July - Aug 2011

Construction Products, Thierry Gillet, says that the secret of Diagrip has been to obtain the perfect mix of diamond and metal powder in the segment. Something that is not so easy since you have to mix heavy small parts with light big parts. “That is even difficult to do when you mix something at home in the kitchen,” says Thierry. “In ordinary diamond tools you therefore have diamond grains packed together in clusters and agglomerations of metal powder in the segment, and that works. But in a Diagrip segment we have managed to calculate and make the mixture in an industrial way with the optimal distance and angle of the diamond grains to give the segment the optimal force in three dimensions. This can be calculated and performed in a laboratory. However, the challenge has been to make the mix and arrangement of powder and diamonds in a uniform, industrial way and that is our in-house expertise today. Another solution could have been alignment of diamonds in the segments, but that takes time and labour and is costly.”

A long Belgian tradition Thierry emphasizes that this in-house know how of diamond segments that has led to the Diagrip technology, has been developed with the experiences of diamond and metal powder mixing that the Belgian plant has had for 75 years. “We have known this technology for more than 20 years, but have needed the time to develop it from laboratory experimenting to industrial manufacturing to fit all our range of tools,” says Thierry.

KOMATSU ON TO In this issue of Movers & Shakers, PDi’s Andrei Bushmarin features Komatsu Europe, a major international manufacturer with a track record that goes back to the late 1960s.

Knepper was backed up by a strong team of Komatsu excavators.

Komatsu from Japan branched out into Europe in 1967 when it set up an office in Antwerp with just seven staff. Over the years, Komatsu Europe changed its location several times until it finally settled in Vilvoorde, north of Brussels, in 1973. Belgium was chosen as a base for Komatsu’s European operations primarily for its excellent logistical capabilities. In the same year a parts distribution centre with a covered storage area of 10,250 m2 was built next to the Vilvoorde headquarters. The parts centre was extended in 1990 by 6,250 m2 in covered space and a further 9,000 m2 outside space. In 1992, Komatsu Europe celebrated its 25-year anniversary with the Prime minister of Belgium, Japan’s ambassador and the Vilvoorde mayor attending the ceremony.

Komatsu Europe International A few years later, the company launched a programme of merging its European assets into one business unit named Komatsu Europe International. Within this programme, KEISA took over Komatsu France in 1996. In 2002 KEISA started to build the second large warehouse extension. The project, completed in late 2003, allowed KEISA to increase the covered storage space by 9,120 m2. In 2006, KEISA moved its key administrative operations, like marketing and finance into new premises in Vilvoorde. It is from there KEISA now handles its international affairs in Europe, Middle East and Africa. It was Germany where the KEISA team played one of the most exciting demolition games in its recent history. The Offenbach stadium, home to Offenbach Kickers FC, is now undergoing a complete redevelopment with the new, state-ofthe -art 20,500 capacity stadium opening in the summer of 2012. Importantly for the club and its fans, the hallowed green turf shall be untouched as demolition of the existing stadium is being carried out around it. The contract to demolish the old stadium was awarded to Lippstadt-based contractor Wilhelm Knepper GmbH. Having being formed back in 1951, Knepper has a long history and tradition in demolition. One of the challenges for the Knepper team was to demolish the existing stands, process and sort the concrete and steel materials and clear the area for preparation of the new stands, without impacting the playing area so that the local team could maintain their home fixtures.

PDi • Issue 3 • July - Aug 2011

Relaying on Komtasu Wilhelm Knepper has relied on Komatsu machinery for over 10 years now, and on this project Knepper had a team of Komatsu excavators. A Komatsu PC350NHRD 23m High Reach Demolition excavator was supported by PC340NLC, PC290NLC and PC240NLC excavators. The PC350 high-reach demolition weighs in at just over 54t, when equipped with the hydraulically variable undercarriage. The hydraulic undercarriage allows Knepper to transport the machine by keeping the width under 3m. The hydraulic undercarriage can be extended to a wide footprint of 3.38m in approximately three minutes, and with the additional weight of 6.2t, the hydraulic undercarriage provides a very stable platform to work from. The PC350NHRD was equipped with a NPK sorting grapple allowing the operator to select and remove the lighter sections of the stand structure. Knepper have the Oil Quick coupling system on their excavators, so the sorting grapple was quickly exchanged for an NPK 2.8t pulveriser to tackle the heavier concrete and steel sections, when required. The high-reach equipment can be exchanged for a digging boom and standard arm with the Komatsu Quick Change system. Knepper were using a Demarec Steel shear MDP30V, coming in at approximately 4.5t in this configuration to process the larger steel sections. Each stand was demolished in phases lasting four to six weeks, with the remaining stands still open so Offenbach Kickers could still play their fixtures in front of a good crowd. To carry out the lower level demolition, cutting and sorting, Knepper employed the standard Komatsu PC340NLC, PC290NLC and PC240NLC excavators, equipped with a variety of crushers, shears, breakers and grapples. Knepper has completed their project, making way for contractors to erect the new stands for the 2011/2012 season. The stadium will be fully renovated by the start of the 2012/2013 season.

Products, service and support According to Wilhelm Knepper’s chief Carsten Knepper, the combination of Komatsu products and the excellent support from Komatsu’s local dealer SchlueterBaumaschinen was a major factor in the success and

OP OF ITS GAME competitiveness of his company. Carsten Knepper’s satisfaction is demonstrated by the latest acquisition of a PC290NLCD kitted out with demolition features. These include opening front guard, 15mm side protection, heavy-duty 9mm undercover, reinforced side links, attachment cylinder guard, additional hydraulic circuits and laminated glass roof window with a wash wipe system. All of it comes standard from the Komatsu factory in Newcastle, England, on the demolition specification. As any demolition contractor will testify, conditions are demanding and often hazardous, so the heavy-duty protection features help protect contractors’ investment and avoid expensive repair bills. Komatsu’s Demolition Line Product Manager Michael Atkinson says that professional demolition contractors appreciate the high specification on the Komatsu demolition excavators. The standard demolition excavators from PC210 to PC450 come with monoboom or straight boom options, and a two-piece boom on selected models. The high-reach excavator range includes models PC240, 290, 350, 450 and PC800 with reaches of 15, 18.4, 23, 27 and 40m respectively.

Demolition textbook available in E-format In the US a university textbook on the demolition process Demolition: Practices, Technology, and Management, published by Purdue University Press in conjunction with the National Demolition Association, is now available in digital formats compatible with all e-book readers. The book is aimed at construction management students as well as contractors, engineers, architects, facility owners, regulators, and anyone interested in how demolition is actually done. “Since its publication in print format in 2010, sales have been brisk,” said National Demolition Association Executive Director Michael R. Taylor. “We expect with the added availability of the book in a digital format to see a big jump in sales. Considering the recent news that e-book sales at Amazon surpassed print books, we think this may become the preferred format among the book’s intended audiences. According to Taylor, demolition contractors intent on training staff properly are making the book required reading as part of the ongoing education p r o c e s s. “The full range of technical issues such as project management, disaster response, demolition project safety, and material handling and recycling covered in the book focus on the real-world skills needed to take on and safely complete demolition projects,” says Taylor. Demolition: Practices, Technology, and Management is coauthored by demolition veteran Richard J. Diven and Purdue University assistant professor Mark Shaurette. A compendium of basic demolition knowledge, best practices, and standards, it is the first textbook of its kind in the US and possibly the world, according to the NDA. The NDA decided to collaborate with Purdue on the book, initially for its specialization in demolition and reconstruction offered through its Department of Building Construction Management, the first such programme in the US. Demolition: Practices, Technology, and Management can be ordered from the NDA store at www.demolitionassociation.com or from Purdue UP at www.thepress.purdue.edu, Amazon.com, BN.com, Apple’s iBooks store, and other online booksellers.

Support Surges for Construction Recycling Alliance In the UK the Construction Recycling Alliance, an umbrella organisation representing companies committed to reducing, reusing and recycling unwanted construction materials, has recently seen an increase in the number of companies joining its ranks. Originally founded with utilities specialist FM Conway as its first member, support for the organisation has been growing with companies including O’Keefe Construction and JPE Aggregates joining. The CRA has also seen support for its Approved Supplier

scheme expand with major recycling equipment suppliers such as CDE Global, Blue Group, Red Rhino and Liebherr GB signing-up. Alongside these equipment specialists other companies such as Ecosheet, International Innovative Technologies, Industrial Shredding Systems and Green Grinder have also joined the organisation’s ranks as Approved Suppliers. Commenting on the CRA’s expansion director David Barnes said, “We have had a fantastic response from the construction industry with both large and small companies joining the CRA. This support has been complemented by other enterprises joining our Approved Supplier scheme. This scheme allows suppliers of recycling equipment or products made from recycled materials to showcase their goods and services to those interested or directly involved in recycling construction materials. The scheme has already proved beneficial for those involved. For example a large construction company contacted us directly wishing to recycle their hard-hats. We were able to put them in touch with Ecosheet who recycle such items, turning them into plastic site hoarding boards.” The CRA will shortly be seeking entries for its first-ever awards programme, the CRA Recycling Awards 2011, which is intended to recognise the achievements of its members and include the following categories: Recycling Contract, Recycling Company, Service and Support, Innovation and Investment. Entries will be judged by a panel of independent industry experts with results announced in the autumn. “One of the principle remits of the CRA is to showcase environmental innovation and good practice and the 2011 Recycling Awards aim to do just that”, said Barnes. The organisation has recently expanded its communication with the publication of regular newsletters and RSS news feed updates, which are available on the CRA’s website.

executive director Patrick O’Brien. “Contractors are finding more work, whether it be traditional concrete cutting or new work created by adding services, and manufacturers are experiencing increased sales while maintaining a new-found optimism about the market.” Of the two surveys conducted, one was tailored to sawing and drilling contractors and consisted of questions about operations and resources. The other was a set of questions sent to manufacturing companies, and focused on current and anticipated demand for their tools and equipment. There is no such information currently collected from this niche market, therefore the introduction of these surveys provides a much-needed information base that is of value to the industry. CSDA is the only association representing the sawing and drilling professionals and so is uniquely qualified to provide this information.

CSDA Annual Convention and IACDS Annual Meeting in 2012

US Concrete Sawing & Drilling Association and international association IACDS will turn their attention to planning for the 2012 Convention in Maui, Hawaii. The event will mark CSDA’s 40th anniversary and is expected to draw an even bigger crowd than the 2011 event. Next year’s convention is scheduled for 7-9 March, 2012 at the Sheraton Maui.

Nearly 50% of Sawing and Drilling Contractors experiencing increased productivity in the US In May, 2011, the Concrete Sawing & Drilling Association conducted an industry-first survey to provide an insight into how their members are faring in the first part of 2011 compared to the previous year. The results are very positive. Almost 50% of the contractors surveyed reported that they have experienced an increase in productivity in the past year. The main reasons given for this increase were a greater emphasis on training and better equipment, while close to 20% of contractors expanded their range of services to bring in new business. None of the contractors surveyed reported any layoffs. The results show that one-third of contractors had increased their labor force by 10% or more, while the remaining respondents reported either a slight increase or a labor force that remained the same. Anticipated manpower requirements for the remainder of the year are also positive, with 62% of contractors looking to either recruit new employees or remain at the same level. The results of the manufacturer member survey were also very upbeat. A healthy 43% of the companies surveyed had experienced an increase in demand for their products. An equal percentage stated that demand had remained about the same. Looking ahead to 2012, all of the manufacturers surveyed anticipate some growth in the sawing and drilling market, with 57% expecting an increase of 5-10%. “The results of these latest CSDA surveys show us that there is an upturn in the sawing and drilling market,” said CSDA

Efficient cutter with superb dust management. The Husqvarna K 3000 Vac is a powerful electric power cutter that delivers out standing dust collection. It’s ideal for in or outdoor locations where you can’t use water or don’t want to spread dust. The quick connection makes it easy to install the Vac attachment, which connects to a vacuum hose. You have good vision of the cutting work, even when the Vac attachment is mounted. Unlike many other electric cutters, the blade on the K 3000 Vac rotates forward, which means you cut more efficiently, with less strain on your body. And it’s equipped with Elgard™, which warns if there’s a risk of overload. Read and see more at www.husqvarnacp.com
