Words from Jan Hermansson

Words from the IACDS President

Life after Bauma Dear Reader, Well, there is life after Bauma. The first six months of the year have been dominated by the German trade show. We ran a Bauma preview in the first issue of the year, focusing on new products that would be at the show. Our second was the Bauma show issue and our biggest ever at 124 pages, since the magazine was founded in 2000.

Instead of further commenting on Bauma, which is covered in several articles in this issue, I will focus on the annual meeting of the International Association of Concrete Drillers and Sawers, which was held in Munich right after the exhibition.

When the meeting’s agenda reached ‘New Members’, delegates were happy to vote in Russia as a new member of IACDS. Earlier this year Russia formed its own national association for professional concrete sawing and drilling contractors. President of the new association is Andrey Kossolapov.

But the next item on the agenda completely changed the tone of the meeting.

Werner Havlena from the Austrian association, and one of the founders of IACDS, announced that the Austrian association had decided to leave IACDS and he read a letter from the association. However, the letter did not explain the reason for the decision, but it was assumed, from the context, that perhaps IACDS, as an international umbrella association, does not live up to expectations. An intense discussion among delegates followed.

Some critics of ICADS have suggested the association is for the mutual admiration among its members. Several delegates confirmed that reactions to the work of IACDS have been discussed in some national associations, but not to the extent of leaving IACDS. However, all delegates realised that Austria’s decision is serious and needed immediate action. Thomas Springer, president of the German association, proposed that an urgent meeting be arranged for representatives from all national member associations to discuss the future of ICADS. Anders Andersson and the new IACDS president Lars Sandström will organise the round table discussion, which is proposed to be held in Amsterdam in September.

Austria’s decision to leave IACDS clearly indicated their belief that their national association does not benefit from being an ICADS member. I understand Austria’s reaction, but at a time with increased competition and the exchange across borders becoming more and more important, I am surprised they decided to leave without suggesting how IACDS could improve its work.

Without a doubt, IACDS has for me a very important purpose, but perhaps members expect too much from an association that only has one meeting a year and currently no workgroups or committees working on separate projects. It is impossible to make a difference that can make an impression on national association members. Big associations pay about €2,500/year, small associations €1,200 and individual members about €400. There are seven big member associations, three small associations and about twenty individual members. So the annual income for ICADS is about €28,000. This is a good start to set up plans of action for the global concrete cutting industry, but far away from the amount needed to really create long-term improvements for concrete cutters around the world.

With so few members that represent a lot of money in turnover for their national associations, the annual fee needs to be much higher in order to really create something on an international level. As a comparison, a national demolition association with more then ten members pays €7,000/year to be a member of the European Demolition Association. If members expect IACDS should do more, then members need to give them the incentives. With a higher annual fee there would be much more room to create something that this industry can benefit from. For instance, as José Blanco has proposed, a common certification programme would provide every concrete cutter that has taken the training course, a licence for concrete cutting. Other training programmes Photo: Vito Gogola. could include wall sawing, drilling, remotely controlled robot techniques, concrete floor grinding and polishing, work environment training, safety and quality training. For me, in this constantly changing and shrinking world we need an organisation like IACDS.

“What a great industry!”

We are in an amazing industry with great potential and I have a great job in it that I really enjoy. My job includes meeting and discussing with contractors and manufacturers from the industry and members and partners in our association. I listen to their needs and try to give them my support and suggest solutions for their queries. The solutions I often pick up are from colleagues in the same association who have encountered similar problems.

In some ways it is all about networking and it is the meetings with people that develops the industry. There are a lot of interesting people in our industry and I am very inspired from meeting them. A good example is the IACDS former president José Blanco who I have now been given the great responsibility to succeed. How do you succeed someone like José, who knows everybody in the industry, is very well briefed, is multi-lingual, works very much for and is passionate about training, the working environment, certification and the cross-fertilisation of the different national associations’ members. He has shown the best from the US association CSDA training programme, the German FBS Handbook and the Australian ANA technical handbook for concrete cutters, to mention a few things. José has a passion that makes you happy and inspired. Inspiring people is very important for our daily work and provides the energy to move on and to develop.

Thank you José for your great efforts with the IACDS and your time as president.

The industry has a great deal of inspiring people. Two examples are Anders Andersson, president of the Swedish concrete sawing and drilling association and owner of the concrete cutting company VOID and Julie White owner and president of the UK concrete cutting company D-Drill.

These entrepreneurs are two sources of pure power. Nothing is impossible and nothing can stop them. It is their kind of energy we need in this industry and in IACDS. I know that Julie and Anders also learn from each other and exchange experiences for implementation in their own countries. In many cases, it is easier to plant ideas in your market from a colleague in another country than from one in your own.

At the recent IACDS meeting held during Bauma there was an intense debate about the future of IACDS and what its most important tasks are. How there is an immediate need to clearly express the purpose of the association and how it should work in the future to improve the situation for its member associations. But in order to find a new form for IACDS, we need input from each member association. We are preparing for a round table discussion in September in Amsterdam with all the member associations. If you have any ideas or questions you would like to raise

at this meeting, please contact me or the IACDS secretary Daniel Trachsel.

My conviction is that an international umbrella association like IACDS needs to have a well functioning network. With a good network we can raise important questions and create different standards for all members to benefit. We have, for instance, created a tolerance standard that can be viewed at www.iacds.com. The IACDS tolerances are universal and represent how big deviations professional concrete cutters should have when drilling and sawing. There are no other measurement rules and that is why we have the IACDS tolerance standards. We have set the limits without any governmental authority interference. It is about initiative and we did it before we were asked to do it and set the agenda. That is an advantage.

When the IACDS Diamond Award was held at Bauma we brought 50 concrete sawing and drilling contractors from Sweden. They all thought it was very interesting and enjoyable. But where were all the other European contractors?

There are so many European concrete cutters linked to IACDS, so why not attend these events and take the opportunity to meet colleagues from other countries and exchange ideas. That is what IACDS is about; it’s for all members not just a few.

IACDS also needs representatives from the younger generation. The world is shrinking and we work all over the globe, which gives us greater potential, as well as challenges.

We also don’t need to meet everytime face to face. Thanks to social media, we can interact in many ways. We need to build relations in our sector in order to compete better with unprofessional players, to get more skilled and efficient. For me IACDS is the perfect forum for that. IACDS is a tool for you, but it will not work unless you use it.

Best regards, Lars Sandström President IACDS www.iacds.org

Words from the outgoing IACDS President

Evolution never ends Foto: Jonathan Alonso.

In 2011, I was appointed president of the International Association of Concrete Drillers and Sawers at the annual meeting held in Brugge, Belgium. It was decided it would be the turn of the Spanish sawing and drilling association AEDT and, as its delegate, I was appointed ICADS president for the next two years.

As I said in my first column for PDi, written after the meeting, it felt somehow offbeat. I am a trade association manager, not a sawing and drilling expert. But a colleague at the IACDS meetings, said to me ‘do not worry, even if you are not an expert on diamond tools, we already have enough around here, but this association is about bringing together the experiences of companies, contractors, suppliers and the entire industry, through national associations… you will do fine’.

Well, time flies and here we are, two years later. In 2013, IACDS held its annual meeting after Bauma in Munich, Germany.

There we appointed Lars Sandstrom, from the Swedish sawing and drilling association, (HIB) as the new president of IACDS for the next two years. Lars is, first of all a good friend, an excellent colleague and a man of the industry. I do not say this because he is a contractor. Lars is the general manager of a national association, but has been involved with the industry for many years.

Lars brings together contractors, suppliers and all other entities related to concrete sawing and drilling, helping them to work together for common goals.

A recent example of his work was the delegation of more than 60 professionals he brought from Sweden to Bauma and the IACDS activities.

My best wishes to Lars on his presidency and I kindly ask everyone to help him to do his job as best as possible.

To end my term and the period of two years in which I have being sharing this column with you, I want to leave you with some food for thought in that evolution never ends. Evolution never ends, anywhere. And, most especially, in a company, because the day you stop with the evolution of a company, you start to lose the race.

As an industry, IACDS also needs to focus on evolution, and for this reason there will be an extraordinary meeting of the association this year. It will be on 18th September and Lars will tell you about it.

As I have said before, IACDS is about bringing together the industry and the main highlight of the association’s activity is its annual meeting. This meeting helps to take the pulse of the market around the world and to see what is emerging. As a sample of the changes, I would like to point out the modification to the logo of the Concrete Sawing and Drilling Association in the US, which now deals with much more than sawing and drilling in related techniques, such as ground penetrating radar and floor sawing.

And now it is time for my farewell and I must give thanks to many people involved with IACDS. First of all, to Daniel and Anna Trachsel, as Secretariat of the association and heart of it, pumping energy to everyday life of the association.

Thanks to all the crew at IACDS. It is like a family of colleagues, friends and excellent professionals, from all over the world. It is a pleasure to work and share experiences with you.

Special thanks to the manufacturers and sponsors of the industry, for the cooperation and support they give to IACDS; they do make it possible.

And last, but not least, thanks to PDi editor Jan Hermansson for his cooperation and publishing my column.

All the best to Lars Sandstrom, and see you around.

Best regards,

Dynaset and Snowek win maintenance award

The specialist expertise and hands on approach of the BAEG team will complement the quality of Atlas Copco products.

Co-operation between Dynaset and Snowek was awarded with Maintenance Developer of the year 2013 at the Maintenance fair in Tampere, Finland. The award was granted for innovativeness, increasing the efficiency, ecological aspects, cost-effectiveness and creating a solution to dust suppression problems. The annual contest is organized by Expomark Oy and Production and Maintenance Association Promaint Ry. “Innovativeness is the key to success. That is going to drive Finland forward. High-pressure dust suppression systems are an outstanding solution, which creates new features to products in its segment. The result of combining existing technologies in a right way is a product that improves cleaning work with better results,” said Ilkka Paasola, a jury member of the contest and the Chairman of the Board, Production and Maintenance Association Promaint Ry. The traditional method of street washing is to irrigate the dust before brushing it off. However, the problem with this process is reverting dust emissions after the surface is dehydrated.

Together, Dynaset and Snowek have created an efficient and ecological solution for street washing. With high-pressure dust suppression technology, streets are brushed in a dry state and atomized high-pressure water mist forms a cover to prevent the dust from spreading to the environment. Surfaces are efficiently cleaned without dust emissions.

When using the new Dynaset and Snowek technology, customers will save in operating costs because the water consumption is only a fraction compared to traditional methods.

Worldwide CSDA Community special survey The Concrete Sawing and Drilling Association is unique in that while it is an association based in the US, it has members from around the globe. In fact, 20% of the membership is located outside the US. Perhaps this is due in part to the fact that the English language is often a second language in many countries. The resources produced by the CSDA are easily accessed by many people whose primary language is different.

Language can be a barrier and also an effective way to connect and conduct business. In my years of interacting with professionals in the concrete cutting industry, I have discovered that there is a strong connection that binds us all. The international community is a generous and helpful group of individuals dedicated to advancing the interests of the industry. Periodic CSDA member surveys and feedback/testimonials consistently identify that networking is by far the greatest member benefit.

Now CSDA members have taken that spirit of cooperation to another level by partnering on projects utilising the respective advantages of each other’s strengths.

A recent job in the Bahamas brought together two CSDA members who met while serving on the CSDA Board.

Tim Beckman of Cutting Edge Services and Skip Aston of Ohio Concrete Sawing and Drilling forged a relationship of understanding and respect for each other’s strengths that ultimately led to partnering on a wire sawing job in the Bahamas to remove a sunken pier. Partnering on jobs is not new to either contractor as they have a history of successful collaborations.

Dynaset demonstrates at Bauma Dynaset drew a lot of attention at Bauma by demonstrating a dirt bike equipped with the Dynaset HVO hydraulic power take off and HPW200 MOBI hydraulic power washer unit. Team Dynaset washed a neighbouring stand’s electric car with

HPW, which got the propulsion from a dirt bike.

With this demonstration, Dynaset proved that their compact hydraulic equipment can be installed on every machine. When a machine is equipped with Dynaset equipment, customers always have electricity, high-pressure water and compressed air aboard.

Record Year for JCB Earnings for the UK based construction equipment manufacturer JCB in 2012 was the best year in its 67 year history, reaching a new record of £365M up from £355M the previous year on turnover which remained virtually unchanged at £2.7bn. In a global market, which, the company says contracted by 10%, sales of JCB machines rose slightly to 69,250, up from 69,100 in 2011.

Over the years I have informally heard many stories of cooperation between CSDA members. One of the more interesting stories occurred at a hotel bar in Tokyo during a study tour to Japan. One contractor, who was just getting started in wire sawing, had just been awarded a large wire sawing job. The more experienced wire sawing contractor volunteered to send his operators to train the novice operators.

Now that is being generous.

But it isn’t just the large jobs where one CSDA member helps another. It happens quite frequently that one member will call another they met at a CSDA convention or the quarterly Board and committee meetings to ask for advice on simple things that one contractor has discovered and learned the hard way, such as the best way to do a job, or run the business side of things. The ease of email and Internet access makes this type of collaboration just as easy internationally, as it is domestically.

These experiences are rather unique in my opinion and are a tribute to the outstanding individuals of this international community. If you are a CSDA member, call and take advantage of the friendly and cooperative relationship between members. If you are not a member, consider joining the CSDA professionals from 22 countries around the globe who are dedicated to advancing the association and the industry. I know you will not be disappointed.

EDA

Stay tuned On television it is very common to hear something like “stay tuned for more…” or “now comes…” It is a reasonable way to inform viewers about what is coming and to keep interest in the contents of the channel.

It is my time now to say this, stay tuned for more at the European Demolition Association. My term as president of the EDA has ended and I will be handing over this unique role, for the very first time in the history of EDA, to a woman, a good friend, an entrepreneur and a true demolition expert, Pilar de la Cruz.

So this is my farewell as president of EDA, and I would like to reflect on what has happened and what is coming. First, I want to thank all my colleagues and friends from the demolition industry for the support and cooperation I received during my term as president, which started in Warsaw in May 2010. In the past three years we encountered many difficulties and changes, as a deep and long economic crisis struck the whole world and will continue to affect Europe for quite sometime.

But difficulties can become opportunities if we work together. In this way, I want to emphasise the fact that the EDA is now a strong organisation, bringing together the industry from many European countries, with national demolition associations and federations from Belgium, Denmark, Finland, France, Germany, Italy, Spain, Sweden, The Netherlands and the United Kingdom.

At the same time the EDA is helping other countries to establish and develop their demolition industries, as is the case with Turkey, the Russian Federation and other countries from the Commonwealth of Independent States.

On the same line of cooperation and sharing, we are working very closely with colleagues from other continents. I want to point out the excellent cooperation of our friends from the National Demolition Association, to whom I wish to thank publicly for their involvement to develop a true international demolition network.

Together we can do much more!

Not everything is brand new because there is a lot of wisdom with senior colleagues, so we started the Club of Honour at EDA to bring together the experience of the past with the goals of the future.

And even if the economic times were not so good, we continued to have the cooperation of many suppliers in the industry, supporting the EDA as sponsors of members of the International Committee. I want to thank all of them for making this possible.

Looking to the future, as waste will continue to become more important for the demolition industry, the EDA has become actively involved with authorities in the European Union, promoting standards for waste management, from the perspective of demolition contractors.

Even more, we founded the European Decontamination Institute, to tackle the issue of hazardous waste removal and remediation, and I am sure you will hear a lot more about this in the future.

And last, but not least, I want to recognise the work done by the Secretariat of the EDA. I tried to share with them the good experiences and the vision to make the EDA a true and enjoyable place for professional cooperation, and I am very happy with the results that we are delivering together.

So, thank you again, and stay tuned for more.

Keltbray’s London awards In the UK, the engineering, construction and decommissioning services company Keltbray has won five awards at the 2013 City of London Corporation’s Considerate Contractor Scheme Awards.

Keltbray secured the most prestigious award, The Chairman’s Cup, as well as a Highly Commended Gold Award for work carried out at 100 Cheapside. The company secured a further three Gold Awards for work carried out at Telex House, Fore Street Avenue, 8-10 Moorgate, 30 Old Bailey and 60 Ludgate Hill. The award of the Chairman’s Cup was based on the company’s promotion of the Considerate Contractor ideals at 100 Cheapside.

“We are delighted that our work is being recognised by The City of London Corporation in this way,” said Keltbray chief executive Brendan Kerr.

“As these awards and our recent World Demolition and RoSPA Gold Award wins demonstrate, we fully support The Considerate Contractor Scheme’s aims by carrying out our operations in a safe and considerate manner on our sites.”

The Considerate Contractor Scheme aims to encourage building and civil engineering contractors working in the City to carry out their operations in a safe and considerate manner, with due regard to passing pedestrians and road users. As part of the scheme, building sites and street works are annually judged on the basis of their overall performance during that year and on a site visit by a specially appointed judging panel.

Slowdown in Europe’s construction equipment market “Russia, compared to other markets in Europe, is doing fairly well for the European construction equipment industry,” said European Construction Equipment Association (CECE) secretary general Ralf Wezel. He was speaking at CTT, the major construction equipment trade show in Russia taking place from 4 – 7 June in Moscow.

The situation in Europe has not changed much in the first quarter of 2013. While Southern Europe is waiting to see some light at the end of the tunnel, Western and Northern Europe are

remaining better off. According to recent CECE figures, sales of earthmoving and road equipment dropped by 20% and 30% compared to the same period the year before. In 2007 the combined market share of Portugal, Spain, Italy and Greece accounted for almost 25% of European sales, in 2013 this amounts to just 3.5%. Construction equipment remains the only sub-sector where slight growth is observable at the moment, though this growth only comes from some regions like Russia, Scandinavia, Turkey or Germany.

The industry expects the situation to improve significantly in the second quarter of this year, as the long winter had delayed construction activity and investments. The recent CECE business barometer confirms this positive trend. Increased confidence of European companies about future sales pushed the business climate index of May over the zero line. However, even under an optimistic scenario with good growth in the next quarters, it will be difficult to compensate the early deteriorations over the year, particularly for earthmoving and road equipment.

In 2012 the European construction equipment industry increased turnover by 3.4% reaching a volume of €25bn. For 2013 it is expected that the overall sales will stay on the level of 2012. European manufacturers are expecting to compensate the drop in European demand by increased sales outside Europe where most markets are supposed to show an upward trend.

The European construction equipment industry pledges for a fairer competitive environment of the industry and open markets. Only under these conditions, the best technology can be taken to the countries to improve infrastructure, living and working conditions, to save costs and to lower bad impacts on the environment. At the moment in Russia non-Russian companies are currently suffering from the disposal fee that the Russian government has imposed in September 2012, which are payable for each wheeled vehicle imported to Russia or manufactured in Russia.

Although CECE supports the approach of the Russian government, CECE, via the Association of European Businesses in the Russian Federation, also advocates equal treatment towards all manufacturers. In addition, CECE identifies the need for revision of the Government Resolution taking into consideration the construction equipment manufacturing, recycling processes, and economic effect of the disposal fee rates for this machinery on the Russian economy. For this reason CECE and AEB are currently working with the Ministry of Trade and Industry on amending the legislation and developing a more balanced one. “We hope that the Russian Government takes into consideration the AEB recommendations and corrects shortcomings of the resolution on recycling fee with respect to the construction equipment industry,” said AEB Construction Equipment Committee chairman Andrey Komov.

Hilti sales growth The Hilti Group increased sales by 3.6% in local currencies over the first four months of 2013.

Positive momentum was felt in the growth markets while sales declined slightly in Europe.

In terms of Swiss francs, sales reached a total of CHF1,370M,(€1,099M), a rise of 4.2% over the same period the previous year.

The highest growth rate over the first four months continued to be in Latin America, where sales were up 20% in local currencies.

Positive momentum of 15.8% growth was also maintained in the Eastern Europe / Middle East / Africa regions. Sales in the Asia/Pacific region rose by 11.4% over last year’s figure.

Development also continued in North America, where sales increased 7.1%. Sales in Europe were down slightly by 3.2% due to the distinct economic slowdown.

“As expected, momentum in Europe has dropped off, mainly as a result of the continuing difficult situation in Southern Europe. This negative trend, however, was compensated by positive developments in North America and in the emerging markets,” said Hilti chief executive officer Bo Risberg. “The profitability improvement programme we introduced at the end of 2011 has kept us on the right track and we’ve been able to further increase profitability according to plan.” In view of current market developments, the Hilti Group expects sales growth in 2013 to be in the low single-digit range.

Aquajet launches world’s smallest hydrodemolition robot The world’s smallest and most flexible hydrodemolition robot, the Aqua Cutter 410, was introduced by Aquajet Systems at Bauma. It has been designed for hydrodemolition applications in confined areas, such as concrete sewer pipes, small tunnels and inside buildings with restricted space. At just 2m long, 780mm wide and 990mm high, the new robot can go through a door opening and weighing 1t it can also operate from scaffolding.

Working typically with between 700 to 2,500bar water pressure and flow of 60 to 180litre/min, the robot handles most concrete removal tasks on floors, walls and overhead applications. It will also replace many applications currently performed using hand lances, providing a safer and accurate operation with the robot.

The 410 robot features a number of tools including a rotor for surface preparation and working inside pipes or tunnels up to 3m diameter, a single lance with a 1.5m shroud for surface removal and a hydraulically operated articulated arm with a reach up to 4m.

The power control module can be disconnected from the tracked crawler. This allows the crawler to be driven into unfriendly environments.

In this mode, the PCM is connected to the track crawler by a cable and the removal process controlled remotely.

The operator controls and monitors the operation by a remote radio controller so that the machine can be run from a safe distance.

Features of the proven Aqua Cutter 710 series of robots, such as equal distance system, the intelligent sensing control, and smart lance system, have been updated and integrated in to the new 410 robot. EDS ensures that no power

is lost due to the nozzle being too far from the surface, which will ensure a 15 – 20% increase in removal capacity. The patented ISC is an advanced sensing system resulting in more efficient production.

The 410 robot also uses many of the same parts from the 710 robot.

Successful Bauma for Bell Equipment “Bauma was a fantastic experience for Bell. It was the biggest Bauma we have attended as well as the largest international exhibition Bell has produced and believe the show was very worthwhile for our business,” said Bell Equipment chief executive officer Gary Bell.

Attracting the interest of visitors was the company’s new E-series articulated dump truck, the proven D-series range and the VersaTruck programme.

Bell’s focus was largely on the new E-series, which was officially introduced with a B30E and B25E. The company’s proven D-series range of ADTs was represented by the B50D, which remains the world’s only production 50t ADT. “With a strong heritage, the D-series still offers true value to customers, setting its own standards in terms of fuel consumption and return on investment,” said Bell.

Bell added that the company sees more demand from the mining and quarrying sectors. “The construction segments in traditionally strong ADT markets are hesitant to invest in new equipment, which results in low overall sales especially in the smaller truck classes,” said Bell.

“Mining and quarrying segments are buoyant and we’re performing well in these industries

At Bauma, Bell also announced the establishment of Bell Trucks America in Houston, Texas, as part of its strategy to re-enter the Americas with the Bell brand following ten years of supplying product to these markets under another brand. BTA is a joint venture by Bell and major investors that will serve as Bell Equipment’s American headquarters, responsible for setting up a comprehensive network of regional dealers and service partners across this territory. This decision follows the co-operation agreement with the nationwide Canadian dealer, Wajax, the first ADTs for which have already left the Bell factory in Eisenach, Germany.

In the Americas, Bell will start by introducing the larger D-Series trucks, which will see the heavyweights, the B45D and B50D, available in the North American markets for the first time. The full Bell range, with the new E-Series small trucks will be available from the beginning of 2014. All Bell Equipment activities in North America will be monitored through its own company Bell Equipment North America. “We’re extremely focused on this development, as this will generate important sales through all the truck classes, as well as secure our European production and parts activities in the long term,” said Bell.

New hybrid engine from Deutz launched at Bauma At Bauma, Deutz and its partner, Terex revealed the results of a pioneering project of producing an excavator, manufactured by Terex Fuchs and equipped with a Deutz hybrid system.

With support from the Federal Ministry of Economics and Technology, Deutz embarked last year on the Green Industrial Diesel project.

The aim was to develop a hybrid drive for the industrial machinery sector, consisting of a diesel engine and an electric motor, in order to reduce both fuel consumption and CO2 emissions.

The target is to reduce CO2 emissions and fuel consumption by 20% to 30%. A compact Deutz diesel engine was modified with a Bosch electric motor to develop an efficient, energy saving drive system, suitable for wide scale use in industrial commercial vehicles with the broadest range of requirements.

The hybrid engine is designed to operate both as a series and as a parallel system. The power source is a Deutz TCD 6.1 diesel engine with flange-mounted motor generator, which feeds electric energy into a so-called supercap pack. Based on the double layer capacitor principle, the supercap pack acts as an electrical energy storage unit. It provides the electric drive with the power it needs to pivot the vehicle’s upper structure. The electric drive motor feeds current back into the supercap pack when arresting the pivoting manoeuvre. The integrated hybrid system achieves additional efficiency benefits through the interaction of the diesel engine and the motor generator. The start stop function automatically shuts down the engine when the excavator is idle. Restarting is also automatic, initiated by the motor generator, which also supports the overall system by providing a power boost when the drive system is operating in the peak load range.

Tower Light’s new products launched at Bauma Italy based, Tower Light, the manufacturer of the world’s largest range of lighting used Bauma to showcase several of their innovative lighting sets and dust control equipment. Tower Light placed their latest development, the very first hybrid battery/fuel lighting tower at centre stage.

The VT-Hybrid is an environmentally sensitive lighting unit that utilises modern energy saving LED lighting with an advanced battery power system. The Tower Light VT- Hybrid features a hybrid battery/diesel system with auto charging technology. The set runs on 90% battery power and 10% fuel. The battery is automatically recharged via a

low battery monitor system through the integral 5kVA generator, combining 7h battery power with 7h generator usage. Tower Light reported immediate and keen interest in their LED lighting towers, which can illuminate a large working area, whilst at the same time make significant fuel savings.

These economies are achievable because LED lamps require considerably less power to work when compared with traditional lighting towers.

With health and safety officials throughout the world starting to stringently enforce the control of hazardous material on sites, the demand for the dust control units is set to grow rapidly. To meet with this impending challenge, DF Ecology, a sister organisation to Tower Light used Bauma to present their new dust suppression unit, the Smart Dustfighter. This is designed to provide outside workers with safe protection from many different kinds of airborne contaminates. The Smart Dustfighter produces a fine mist of water through a series of high-pressure jets. The mist is then propelled onto the site by a powerful fan, rendering the area free from unhealthy and hazardous material. Similar in size to a mini cement mixer, the Smart Dustfighter operates from main power of 230V 50 Hz 2.2KW, with a 110v version available for the UK. The Smart Dustfighter delivers a maximum coverage of up to 13m through six nylon fan blades fitted to an aluminium hub connected to twelve stainless steel water nozzles.

New Hilti DST 10-CA wall saw At Bauma, Hilti launched the DST 10 wall saw generation equipped with wireless remote control and electronic assistance known as CutAssist.

The DST 10-CA can make straightforward cuts virtually all by itself. The operator’s hands remain free, allowing other tasks to be performed, such as preparing the next part of the job. This saves time and makes diamond sawing more costefficient. Thanks to CutAssist, the system operator is required to enter only a few simple parameters, such as cutting depth or blade diameter before pressing the start button.

power output of 9kW and maximum cutting depth of 380mm, it makes cutting or extending openings for windows and doors, or openings in floors easy. The new Hilti DST 10-CA also cuts reinforced concrete, masonry and natural stone in applications on building facades and balconies with utmost efficiency and reliability. Drawing its power from a 16A electric supply, the DST 10-CA utilises the available main’s power thanks to Hilti traction control. This feature ensures the system always achieves optimum performance.

The Hilti Equidist saw blade line is matched to Hilti wall saws, ensuring higher cutting performance at lower total blade costs. Thanks to Hilti Equidist technology, the individual diamonds in the blade segments are evenly distributed avoiding diamond clusters and bare patches in segments.

Higher cutting performance is the result. Equidist saw blades are suitable for universal use, so that only one blade specification is needed to cut various types of concrete. The new Equidist technology increases the rate of cutting progress and extends blade life compared with standard technologies, the company claims.

www.hilti.com

The Hilti DST 10-CA’s wireless remote control unit provides real time read out of cutting depth on its display and, at frequency of 2400MHz with frequency hopping technology, this wireless system has a range of approximately 20m. In addition, thanks to integration of all electronics in the saw head, there is no longer any need for a separate electrical box and the cumbersome tangle of connecting power cables, motor control and remote control cables. The integrated control electronics also eliminate lengthy setup and transport times, allowing the operator to begin cutting without delay.

The new Hilti DST 10-CA wall saw system comes into its own particularly in tight spaces and where access is difficult. With its continuous

control system for convenient alternation of hydraulic tools. These ergonomic, active safety components positioned within the operator’s line of vision show in real time the tool position and the machine’s inclination. Should a critical point be exceeded, the LDC automatically triggers the electronic reach limitation. Once the reach limit has been attained, it prevents any further equipment movements that may reduce the machine’s stability.

Liebherr also showed the L 576 wheel loader with the latest engine from the generation complying with IIIB / Tier 4i exhaust emission limits. The version on show had a 4.5m3 rock shovel with delta-pattern cutting edge and ESCO V33 AD teeth and segments.

Liebherr continues to use the hydrostatic drive concept together with Liebherr power efficiency, which is an electronic mapped-characteristic control system. This increases the machine’s handling power and keeps fuel consumption to a minimum. Compared with other machines in the same size category, the driveline concept cuts fuel consumption by as much as 25%, the company claims.

Construction sites function in a processoptimized way Excavators have evolved more and more into multi-tasking machines in recent years. This has been made possible through the rapid development of quickcoupler systems, like the fully hydraulic Variolock system from Lehnhoff Hartstahl located in Baden-Baden/Germany an innovative supplier of hydraulic excavators and hydraulic excavator attachment. Thus, the processes on construction sites can now be optimized, whereby sometimes it can prevent the need for several excavators on a construction site.

Process optimization is a must on construction sites today. Only with an optimized timing device can contractors successfully counter the high costs involved. The fully hydraulic quick coupler Variolock system from Lehnhoff brings the necessary flexibility to the construction site.

An excavator equipped with the Variolock system can handle multiple tasks in rapid succes-

sion, and is a universal tool carrier. Idle times are a thing of the past for the excavator, for example when loading trucks. It must no longer stand idly waiting for the next truck, but simply changes the next hydraulic or non-hydraulic attachment within seconds. From grabs to hammers, demolition shears, tilt buckets, compactors, and much more. This rapid change is carried out easily by pushing a button from the driver’s cab and also worthwhile for short work cycles. Thus, tools are used less for purposes other than intended, and do not wear out prematurely.

The tool change is easily controlled by pushing a button from the driver’s cab, and all the functions of the hydraulic tools are available immediately after the change. This is made possible by the fully hydraulic circuit and energy-coupling system with innovative valve clamping technology that distinguishes the Variolock.

Five integrated valves open over an extremely short hub of only 3.5 to 5 millimeters. Through this “heart” the maximum amount of oil flows within the shortest possible time. With the tool recognition option, the operating pressure and flow rate is set automatically. With this high-tech system all hydraulic circuits of the attachments are consistently safe and free of leaks associated with the hydraulics of the excavator; even if the Variolock system is also combined with tilt, rotate or tilt-rotate unit.

The Variolock quick coupler systems from Lehnhoff Hartstahl are designed and equipped for tough job-site applications. They also cope easily with high torsional moments as they occur during demolition, for example. Made in Germany - from development to production - is a feature of every Lehnhoff product. Short-stroke valves are also a

proprietary development from Lehnhoff.

Technologies such as the Variolock system are continuously developing at the Baden-Baden manufacturer. During this optimization process they listened very carefully to the experiences and needs of their customers. With the result that performa nce efficiency and service life is constantly being improved; this in turn pays for the construction site.

Appointments on construction sites can only be kept when man and machine have sufficient power reserves. Lehnhoff customers confirm that 2,000 operating hours per year or more, even at high loads, are not a problem for the Variolock.

But even a “continuous run” needs a team in the background that is available in the worst case scenario. Therefore, the Lehnhoff service is ready and willing to help quickly, competently and efficiently.

The self-contained Variolock system with its flow-optimized valve geometry is based on the Lehmatic quick coupler from Lehnhoff, which has been proven over 100,000 times. When changing to Variolock, which is available for all excavators from 2 to 130 tons, a modification of existing Lehnhoff attachments is not required. The system is also designed to be very low-maintenance, so that downtime can be minimized.

A nice “side effect” of Variolock of the system performance is reduced energy consumption.

Since these quick release mechanisms work with minimal power loss, less fuel is consumed accordingly. In other words, the excavator can do more per liter of diesel.

So this is an investment that pays for itself very quickly.

Management buy out at Heger

HTC’s new tools

At Bauma Heger communicated this significant change and Heger customers can now expect even higher flexibility and focus on their demands.

In the 105 years of manufacturing diamond tools the German company Heger has faced many changes in its organisation. In 2001 Heger was acquired by ITW based in Chicago, USA, an international group with more than 850 companies and a wide range of industrial activities. Together with the former Belgium-Dutch Toolmatic group Heger was the only manufacturer of diamond consumables in the construction product division of ITW. After a change in the long-term strategy, ITW and the two managers Stefan Haag and Günter Dreyer worked out a management buyout deal to split away the German part of the Heger Group. The two directors founded Heger Excellent Diamond Tools to take over all operational activities.

The new Greyline Superprep diamond tools from HTC are aggressive in many ways. With matrix technology, HTC has created aggressive tools with aggressive prices.

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

In the second quarter of 2013 the new Heger will again set up a segment production department in Heitersheim to manufacture the complete product. The focus of Heger will remain in the professional drilling and sawing market with manufacturing drills and blades. Heger also manufactures specialised products for refractory and ceramic material. With the start of a distribution agreement with Braun from Austria, Heger can also provide machines and equipment to its customers.

A foot-actuated 90.8litre dustpan provides increased collection and dust-free emptying, while 4.46m of Ruwac’s MicroClean filtration ensures the vacuum system will never clog. Optional HEPA filters are available.

The exceptional cleaning power, durability, multiple operator usage and safety of Ruwac’s DS2-EX Series explosion proof vacuums makes them one of the most economical solutions currently available.

Ideal for heavy pick-up in and around production equipment, storage areas or for use as a central vacuum system, these continuous duty vacuums will not only remove the risk of a possible explosion, but will increase productivity while turning the workspace environment into a dust-free zone.

Sila 600A for smaller areas The Swedish manufacturer Sila is expanding its range with a smaller model, Sila 600A, that has a capacity of 600m3/h. It is designed for smaller areas, such as bathroom renovations and minor renovation work on surfaces up to 4mx5m.

“The big difference between Sila 600A and other air cleaners for small areas is that we have created a new design.

We have built it at the height instead of depth to create a filter surface that is double the size for the important preNewcomer Sila 600A with filter. Due to this the capacity of our 1000A and 2000A at Bauma air cleaner does not shrink as quickly,” said Sila marketing manager Andreas Lundin.

Another major benefit is it is narrower than other smaller air cleaners and better adapted for use in enclosed spaces. “You can, for example, place the air cleaner in doorways, as is common, without it taking too much space. It’s easy to pass it,” said Lundin.

As for the larger Sila models, there is also the new

accessory, the decontamination frame, on Sila 600A. It allows the creation of secure barriers between clean and poor air. It is also possible to connect an evacuation hose to the exhaust to remove the air to the appropriate doorway, window or other opening. “But instead of a regular spiral hose, we have created a plastic hose roll, 200m long, which is easy to mount with four screws and cut to the required length and then throw away when the job is done,” said Lundin.

Dustcontrol launches new air cleaner Dustcontrol is launching its new air cleaner DC AirCube 1200 with eco fan. This is a compact, robust air cleaner in power and size between the AirCube 500 and AirCube 2000 models. The company has also updated the AirCube 2000.

DC AirCube 1200 can be used in larger rooms thanks to its high capacity of up to 1,060m3/h. The fan is a radial blower with a nested fan house to build up high pressure within the flow field. This means that the unit is operating with high airflow. The fan also has a variable speed control in order to save energy, for example, at night. The new air cleaner Roger Berglund, chief exhas a chassis of stainless ecutive officer Dust Control steel to be extra resilient in Germany, demonstrating the new air cleaner, DC to damage.

The renewed DC AirCube 2000 is a robust air cleaner with eco fan that has an output of up to 1,800m3/h. That makes it the market’s most powerful air cleaner single phase, according to the company.

New generation from V. Brøndum Danish company V. Brøndum is extending its range of Ronda air cleaners for the construction industry with a new negative pressure unit Ronda 600 NPU. The Ronda 600 NPU is very easy to use, has a very low noise level and is equipped with warning lights for clogged filters.

The air cleaner is designed with a focus on durability and ease of use and it is the first of a new generation.

Ronda 600 NPU is built around a centrifugal fan, which ensures a high airflow of maximum 600m3/h, even when the filter is clogged.

DC AirCube 2000 has a pre-filter of 0.7m2 and a micro-filter, HEPA H13, of 10m2, which cleans the air from harmful particles in a very efficient way down to 0.3microns. DC AirCube 2000 is also equipped with an indicator light that glows when it is time to replace the filter.

Air exhaust is directed upwards so as not to stir up dust from the floor. The machine can, if necessary, be put down on the floor with the exhaust on the side.

The ergonomic design also makes it easy to carry and transport.

Ronda 600 NPU is suitable for renovation, demolition and painting where it removes hazardous dust from inhaled air. It minimises the need for cleaning and prevents the spread of dust outside the work area. “The new vacuum unit has been designed with a focus on ease of use, reliability and low operating costs, and we have had a great interest in the product, not least at Bauma,” said Brøndum managing director Per Brøndum.

A new feature is that Ronda 600 NPU is based on a cylindrical filter, which consists of a washable pre-filter and main filter. The large cylindrical HEPA H13 main filter has an area of 9.2m2. The very large surface will give the filter a longer life, a lower pressure drop across the filter and, thus, a higher airflow. It is easy and dustfree to change the filter.

Brøndum has also recently launched a new ecofriendly and compact wet cleaner called Ronda 370. This wet cleaner can be connected to concrete cutting and drilling machines and supply water for the cooling and at the same time as the dirty cooling water and concrete sludge is being collected.

Ronda 370 is equipped with a disposable filter sack that cleans the drilling sludge. The filtered water slowly seeps back to the container of the machine from where

The Ronda 370 in action

it will be pumped to the concrete drilling machine or saw, as fresh cooling water. This process is repeated until the filter sack is full with concrete sludge and ready for disposal. In this way the work is facilitated, water is saved and the environmental impact is considerably reduced.

Ronda 370 is equipped with a 1.2kW by-pass suction motor and trolley frame with wheels ensuring that the machine is easy to manoeuvre. It is also available with standard vacuum cleaner accessories and can be used as a heavy-duty wet cleaner for general cleaning tasks.

Pre-separator with big bag sac Pullman Ermator recently introduced the pre-separator C5500B, which is a development of the traditional mobile C5500 that has been on the market for some time. C5500B is set at a high frame construction and the collection takes place in a sack that holds 1m3.

C5500B provides a significantly longer operating time when the bag does not need regular replacement. It is very smooth and easy to replace the bag. A pallet is placed under the sack before starting to fill and when full the pallet and sack can be removed with a forklift. C5500B has 76mm cam lock connections and comes comPullman Ermator recently introduced the C5500B pre-separator, which is a development of the conventional mobile C5500.

Despite its volume the IC300 is easy to move and it is also emptied easily with a forklift. IC300 is available in two versions, with 63mm or 76mm cam lock connections. It is also available with 150litre and 600litre containers.

Also from Pullman Ermator is the new precipitator S26 chip extractor, which has been designed for saws in professional use and adapted for connection to a container system. This chip extractor is equipped with a rinsing offense coarse filter and HEPA H13 filter. The cyclone has a special design where the dust can fall directly into the bag so as not to clog fil-

screws and other things that can occur on a construction site, before reaching the dust extractor. This increases the dust extractor’s overall capacity and extends the life of the filters. The pre-separator is height adjustable and the large rubber wheels make the machine easy to move around.

The new pre-separator GL PS built in dust extractor HTC 80 iD, which increases productivity by up to 15% compared to traditional dust extractors, removes up to 95% of the dust,” said HTC Group chief executive officer Lars Landin.

The new GL PS is not just another trashcan separator as it has been designed for optimum airflow to separate large particles. Also, the by-pass valve makes continuous operation possible. The operator can change the dust bag in the pre-separator without turning off the dust extractor and therefore save time.

The Longopac system that is standard on the GL PS also makes the handling of dust convenient. Other features are adjustable height for easy transportation, antistatic hoses with cam lock system and large rubber wheels. “In addition, our new pre-separator GL PS built in dust extractor HTC 80 iD, which increases productivity by up to 15% compared to traditional dust extractors, removes up to 95% of the dust,” said HTC Group chief executive officer Lars Landin.

South Africa’s demolition industry:

Can it weather the current rage of storms?

Five years ago PDi looked at the South African demolition scene. Our Africa desk once again assesses the situation. Jessica Hannah reports.

T

he demand for demolition in South Africa to some extent imploded along with the general commercial and industrial slowdown experienced throughout the world, post 2008. However, the huge demands that were made to stage the 2010 Soccer World Cup in South Africa carried the construction sector, one of the main drivers of demolition in the country. Stadia were built and upgraded, extensive transport systems put in place and airports upgraded or constructed. From 2010, the country was exposed to the global downturn contagion, which undermined the principal industries that support the demolition industry.

Along with this was the government’s inability to deliver on game-changing capital projects, which were promised, but not followed through and made it difficult for the demolition sector to source work from lead contractors. With the country on the cusp of its fifth general election in 2014, the government and para-statals, such as Africa’s leading logistics provider, Transnet, have turned up talk about huge multi-billion euro projects, to the scepticism of the private sector about them materialising.

The situation has not been aided by eighteen South African construction firms, including the six biggest companies, admitting to wholesale collusion and price

fixing with regards to 300 identified cases of illegal or irregular behaviour for contracts worth about €4bn.

The country’s Competition Commission is investigating the matter.

“It is well known that in many commercial and industrial sectors, economic activity has been under considerable downward pressure since 2008, owing to the international financial crisis and to internal South African political and social factors,” reports local diversified company Jet Demolition. “This led to reduced overall demand for demolition services, and more postponement of industrial and mining projects where they are not absolutely critical to sustaining dayto-day production activities. To a considerable extent, the pipeline of commercial and industrial projects has been negatively affected over recent years, with industrial plant maintenance, replacement and upgrades often being reduced or curtailed.”

Intensifying cost pressures throughout the economy have also resulted in a tendency to choose the lowest cost provider of demolition services, often to the detriment of safety, quality, and environment and, by extension, society at large. This was recently highlighted by the number of illegal rubble dump sites in the country that have been revealed and the enormous cost to remove them. These are used a lot by companies that exploit

low fines if caught illegally dumping and, of course, they do not have to incur the cost of legal dumping and use the savings to undercut the more established operator.

is an important feature, however, there is not a great demand for indepth analyses and reporting on the industry,” says Kat McClure, general manager of Industry Insight, one of the leading construction industry research bodies.

Pressure groups, sick buildings, history, court action in the future mix

Rising up: high rise buildings in South Africa are becoming increasingly needed.

and blatant disregard for responsible environmental practices and legislation, appear to be on the rise, with the number of contracts being awarded to unqualified and inexperienced companies also increasing.

Unfortunately, South Africa still does not have any controlling body, association or specific legislation to police demolition industry participants and operations.

Wreckers group chairman Mike Perkin agrees, adding that the most significant challenge for South Africa’s demolition industry is people who think they are demolition experts and have no experience.

Atlas Copco Business Line Manager, Construction Tools Division Neville Stewart says that the South African demolition industry remains small, as it is a relatively young market with few old buildings requiring demolition. There are a few specialist demolition companies, with most being small companies involved in minor residential projects. Most demolition equipment is used in quarries and mines.

“Within the major construction sector demolition

In the firing line: the 2010 Soccer World Cup stadiums have become white elephants as calls for the Cape Town Stadium’s demolition increases.

28 PDi • Issue 3 • June - July 2013

While many in South Africa’s demolition industry view the short-term future as relatively bleak, the medium to longterm view is more sanguine, as buildings and other structures become older and less safe, requiring demolition.

An element that will help sustain the demolition industry is ‘sick’ buildings. Ironically, they are glaringly prevalent in the country’s health sector. One of the grander plans the government appears determined to see through is its National Health Insurance implementation to provide universal affordable quality hospital and clinic care to all.

The outcome of a €12.7M pilot project and research was the conclusion that many of the country’s clinics and hospitals that have served its population to date would need wholesale upgrading, extending and in many cases, total demolition. This means potentially hundreds of small and large health care facilities are to be adapted or re-built, which will provide an injection of demolition activity, both urban and rural.

A further potential boost could be facelifts of major cities such as the Foreshore Freeway in Cape Town, which could be demolished following a significant chunk of its population calling for its removal after decades of leading to nowhere.

The country’s principal airport, OR Tambo International in Johannesburg, is now to be developed into an Aerotropolis, a commercial hub of retail and entertainment, as well as serving as the country’s principal aerial gateway. Potentially significant internal and external demolition possibilities to reconfigure its space to suit the new plans are expected.

Even the recently built are under threat. The 2010 World Cup was a boost for demolition and its legacy could also be. The tournament left a bitter pill to swallow in some cities, a high maintenance white elephant stadium. There is a lobby calling for the Cape Town Stadium to be demolished and used for other things, or even left undeveloped, as it is seen to be a drain on the city’s stressed finances. This has precedent, as it was a solution adopted by South Korea for some financially challenged stadiums following its co-hosting of the soccer showpiece in 2002.

Bridges to no where: the majority of Cape Town’s residents are calling for the demolition of the Foreshaw Freeways, which end in mid-air.

Also wanting to tear down the recently built were affected residents and environmental pressure groups opposed to a controversial R54M (€4.5M) toll plaza and office construction. However, the court ruled in the development’s favour and it remains.

In Johannesburg there are calls for a series of housing developments to be demolished.

This threatens twenty-eight houses in a court challenge by iron and steel giant, ArcelorMittal. The South African government allegedly built the homes as part of its Reconstruction and Development Plan. The problem is that they are on the company’s land alongside a railway track that carries its ore. In the company’s application to the High Court, it states a train derailment there will be catastrophic for the community living there.

Towards the end of last year over 250 houses were demolished in Lenasia, in Gauteng, because they had illegally been built on land that was reserved for government housing. However, fraudsters had sold the land to homeowners and provided title deeds with the government’s logo on it. Some of the people living there had been there for ten years and were left homeless.

The Gauteng provincial government is looking at demolishing ten buildings it acquired in the Johannesburg CBD. All the buildings are over 55 years old.

Once demolished, two inner city blocks will have been flattened to create a central city square, but general public consensus is against the demolition of the buildings due to historical value.

Meanwhile, Durban on South Africa’s eastern seaboard, and home to the busiest port serving the African continent for over a century, is also seeing history almost get in the way of plans. Although there was some public resistance to the demolition of a number of colonial style buildings, as well as Union period structures to make way for new high-rise buildings, the local heritage guardians found the claims to be unfounded. The constructions are in line with the city’s plan to curb urban sprawl and consolidate water and electricity supply within the next twenty years.

Building bridges: a bridge in Nemfwe, Zambia, which was demolished and rebuilt.

Opportunities in continental Africa As South Africa is to some extent a retail gateway to Africa, although both Kenya and Nigeria, constantly

challenge this contention, so it is also with the provision of demolition, many times in competition with overseas demolishers. The major demolition companies in South Africa constantly pursue business in other African countries.

South Africa is the single-largest Foreign Direct

Investment contributor into Africa, according to the lead partner at the Ernst & Young Africa Business Centre. The country is also now part of the Brazil, Russia, India, China, South Africa trading bloc, thus giving it some preference in the plans of the two major growth economies of China and India, seeking to fuel hungry economic growth levels. Both countries have invested heavily in infrastructure development to improve rail, road, port, communications, and other economic imperatives to access the continent’s metals, minerals and oil.

The two are also positioning themselves to take advantage of the huge consumer market Africa represents, as its fifty countries become more democratic and wealthier. Many of these initiatives will require demolition.

Within particularly sub-Saharan Africa there is a great need to refurbish or renew war and neglect-ravaged infrastructure to drive the new focus on intra-African trade, so the money remains within the Southern African Development Community members.

An updated report by audit, tax and advisory firm KPMG has found that foreign direct investment into Africa will continue to increase and what is seen currently is only the tip of the proverbial iceberg.

“Africa will continue to be one of the largest foreign direct investment destinations and has some of the fastest growing economies,” says KPMG chairperson Yunus Suleman, adding that the continent had much more to offer.

Focus on Cape Town

Implosion contract might collapse in court One of the more spectacular recent demolitions was the downing of the twin Athlone cooling towers in Cape Town.

It is now the subject of court action about the contract for it. Cape Town Mayor Patricia de Lille believes that, although an earlier independent investigation into the awarding of the €1M tender found no evidence of fraud

or corruption, she is taking it to the High Court to decide on the validity of the contract. She launched her action earlier this year and a date has yet to be decided for it to be heard in court. Some officials within the City Council allegedly close to the awarding of the tender have been suspended.

Mired in controversy: the demolition of the Athlone cooling towers has now led to a legal battle over the validity of the contract.

any superlatives have been expressed about the recent Bauma trade show in Munich, which provided exhibitors and visitors value for their money. Perhaps the only negative from the show is that it is now far too big and impossible for visitors to see everything, so PDi will spread its reviews of the relevant equipment over several future issues. Jan Hermansson reports.

A record breaker This Bauma broke all previous records for exhibitor numbers and exhibition space, as well as attracting the highest number of visitors. Around 530,000 visitors from over 200 countries decided to attend the seven day show. The proportion of international visitors has never been higher, as over 200,000 visitors came from outside Germany. And 3,420 companies from 57 countries exhibited, including 1,346 from Germany and 2,074 from abroad on a show ground covering 570,000m2.

“This show is very good for our industry in these turbulent times and it will certainly give it a boost,” said Johann Sailer, chairman of the Construction Equipment and Building Material Machinery Association of VDMA and president of the Committee for the European

Construction Equipment Industry (CECE).

“Our exhibitors were delighted with the quality and the international spread of the visitors. Good business has been done here. With over 200,000 visitors from outside Germany, the number was higher than ever before. The response this year has simply been outstanding,” said Klaus Dittrich, chairman and chief executive officer of show organiser Messe München.

“It is an amazing show for us and perfect timing as we have made a management buy out of the company and are really aiming forward for Heger Diamond Tools,” said one of the company’s new owners, Stefan Heger.

“An amazing show for us and we did a lot of business, so it really paid off,” said WideCut Korean diamond wire representative Shelly Han.

Sawing, drilling, grinding, polishing and demolishing For the concrete sawing and drilling industry, Hall A1 was the most important as most manufacturers were located in this arena and demonstrating products just outside. Husqvarna Construction Products had a big impressive stand inside and a large outside

demonstration area. Tyrolit and Hilti had similarly large exhibits. There were also demonstrations of floor grinding and polishing equipment from companies like HTC Sweden, Superabrasive, Schwamborn, Saint Gobain and Stihl, which had stands inside and out.

Husqvarna presented a wide range of equipment, including a new high cycle platform, new wall saw, the new ring cutter K3600 and a new drill motor DM650. The new diamond tool range Diagrip2 was also displayed. Also new were a power cutter K760 and two new mid-size demolition robots.

Hilti presented its new DST 10-CA wall sawing system, which aims to speed up and simplify machine operation. This is achieved thanks to a special app called CutAssist. Built into the wireless remote control unit, it sets up and controls the system operation. All the operator has to do is enter a few parameters before the cutting.

Pentruder launched a new RS12-NTGRA integrated wall saw. NTGRA means that the drive motor and the electronics are integrated with the saw. No separate power supply is needed and the only connections required are a 3-phase cable and water.

Granada-based Sima showcased fresh additions to Issue 3 • June - July 2013 •

its Cobra family of floor saws. Also standing out from Sima’s display were the rebar cutting device CEL-42, designed to cut corrugated steel of up to 36mm in diameter, and the new masonry saws from the Dakar range.

German company Lissmac premiered its environmentally friendly floor saws, Compactcut, Multicut and Unicut, built around the principle of efficient use of water and electricity. A member of the Blue Competence Alliance, which is an ecological initiative by German engineering association VDMA, Lissmac focuses on the development of eco-friendly machines, which use IIIB-compliant drives and require less cooling water and fuel.

Swedish manufacturer Aquajet Systems launched a

new hydrodemolition robot named Aqua Cutter 410, which is the smallest and most compact robot on the market. The robot is designed for extremely tight spaces.

Aquajet was also showing its model Aqua Cutter 710.

Conjet, which also manufactures hydrodemolition equipment, launched an upgrade to its robot 322 called 327. The new robot is provided with a new control system. Conjet also showed the popular as well as the world’s smallest jetframe system Conjet Nalta.

HTC Sweden showed their latest news: Diamond Xpress, Big Block Xtreme, HTC 80 iD, HTC 1500 and HTC ixT 800RX and more. In the same corridor not far from there, Pullman Ermator displayed their wide range of dust collectors, air cleaners, and especially their pre-separator. This spring, they launched no less than

three types of pre-separator incliding a big bag version.

Scanmaskin also brought their new equipment, which included among other things, the new height-adjustable dust extractor ScanDust 2900, floor grinders Scan Combi Flex 330 (excellent for edge grinding), 450NS, 500PD and 500i. They also revealed their new floor sanding for wood floors: Scanmaskin 18.

Hilti also highlighted its new focus on GPR radar equipment, something that is starting to gain ground in Europe. In addition, they also showed a diamond wire offering safer and more efficient wire sawing.

Most futuristic booth was Tyrolit’s four centres for drilling, sawing, floor sawing and milling. New was the Bump-Grinder PC4500 from Tyrolit’s US subsidiary Diamond Products. Also new were the drilling systems DRU250 *** *** DRA400 and floor saw FSG513 ***. Floor grinding and polishing equipment with associated dust handling equipment was also prominent with manufacturers such as HTC, Scanmaskin and Pullman Ermator. Other leading brands on display were Schwamborn, SASE with German partner MKS Funke, Klindex, Blastrac and Dr. Schulze, which launched its own programme of floor grinders. Dustcontrol exhibited through their German subsidiary and showed their air cleaner Aircube 1200, Aircube 2000 and the new DC5900 dust extractor for floor grinding.

On the air cleaner side the newcomer Sila Products showed some of their range, including the remediation framework that allows the renovation of small spaces dust free.

Another popular feature among mainly German manufacturers Lissmac, Cedima and Rellok included the large floor saws. Many had taken up the product to track milling grooves in asphalt and concrete.

Gigantic outdoor area The outdoor area was at least twice as large as the indoor space. Many exhibitors also had large exhibits outside including Volvo, Caterpillar, Hitachi, Case, Liebherr, Kobelco, Indeco, Brokk, Furukawa, Allu, Demarec, Atlas Copco, Sandvik, OilQuick, Avant Tecno and Chicago Pneumatic. Also outside were a number of

32 PDi • Issue 3 • June - July 2013

manufacturers of mobile recycling equipment, such as Rubble Master, Atlas Copco, Sandvik, Metso, Gipo, Innocrusher, and Rockster.

Chicago Pneumatic showed five new additions to the RX breaker line. Ranging in weight from 1.8t to 4.2t, the new breakers RX 26, RX 30, RX 38, RX 46 and RX 54 fit 20t to 70t carriers. All models share the same features including Power Boost, which uses the recoil energy to increase breaking performance; a PowerControl Plus valve enables the operator to adjust the operation mode to the application, and a noise and vibration-damping system.

Netherlands-based Hydraram debuted a new demolition jaw, which extends the range of interchangeable jaws for the company’s MK series of multiprocessors. Currently, Hydraram offers six types of jaws for different applications, with two more for recycling and rail cutting coming in a few months.

Atlas Copco expanded its jaw offering by launching a new mobile shear jaw that turns its CC 3300 Combi Cutter into mobile shears. The MS version completes the series of other jaw models available for the CC 3300 that previously included universal jaws, steel cutting jaws and box shape jaws.

For demolition attachments, the Italian manufacturers launched a number of new products.

Indeco, for instance, displayed a wide variety of their range of breakers. Indeco also launched a new scrap shear for excavators, the Indeco IBS pedestal boom system, a line of rotating compacts and new models of their sorting grabs. The Italians are still struggling with their domestic market, which is very weak. So most manufacturers are focusing on exports. Most of the Italian companies, like Trevi Benne, VTN, Promove and Simex showed their products. Trevi Benne showed their concrete crushers with a booster system making their equipment both stronger and faster.

Quick couplers The quick coupler is a small but indispensable tool that can considerably speed up the work of an excavator operator. There are a few types of quick couplers, but it is the fully automatic devices that really make the Risto Kakela: the President and Owner of Avant Tecno

difference for excavator operators and owners. Only a handful of manufacturers, including Oilquick, Wimmer, Lehnhoff, Riedelberger and Miller, were active in this segment before Cat Work Tools developed its own automatic system called auto-connect.

Quick couplers are a trademark product of Austriabased Wimmer, and one of the highlights was the Oilmaxx V8. Available in six sizes, the Oilmaxx V8 fits excavators of 15t to 40t.

Lehnhoff Hartstahl from Baden-Baden, Germany showed its own version of a fully automatic coupler called Variolock. Based on proven Lehmatic technology, the Variolock quick coupling system is available for 2t to 130t carriers. Robustness and reliability are the two qualities that Lehnhoff focused on when designing the Variolock. According to the company, the coupler can clock up over 2,000h/year without malfunctioning. Five

integrated valves open into a hub of only 3.5mm to 5mm to ensure the maximum oil flow within the shortest possible time. Thanks to a tool recognition option, the operating pressure and flow rate are set automatically.

Excavators In the excavator segment, ever-tightening emission regulations are the main force that drives development.

Komatsu Europe International supplemented the Dash-10 series with a new short tail swing excavator.

With an operating weight of 13.4t to 14.5t, the PC 138US-10 is designed for jobs in confined areas. The excavator is powered by a Komatsu 71kW Tier 4i/ Stage IIIB-compliant engine, which boasts improved performance, while having 7% less fuel consumption than its predecessors.

machines with three new Tier 4i-compliant excavators.

The company also premiered two Tier 4 Final mid-size short radius crawlers.

Volvo CE used Bauma to unveil the low-emissions technology used in the company’s forthcoming Stage IV/Tier 4 final-compliant machines. The engine system, which is already used in over one million Volvo Trucks, is set for launch in January 2014.

Mini-excavators, loaders, telehandlers Ausa presented a wide range of dumpers, forklifts and telehandlers, but the main attraction was the T144H Plus, a compact telehandler that offers a viable alternative to conventional skidsteer loaders. The T144H Plus telehandler topped the list of Ausa bestsellers, closely followed by the D600 APG and D1000 APG dumpers, which remain Ausa’s core business.

The Franco-German manufacturer Mecalac showed

13 models of compact loaders with a bucket capacity range of 0.5m3 to 3m3 and the MCR mini-excavator range, which is now available in 6t, 8t and 10t variations.

Another heavyweight in the compact segment, France-based Yanmar displayed its zero tail swing midi excavator ViO80-1A, now fitted with a new Stage IIIBcompliant engine. The 4TNV98C-WBV engine, which is equipped with a particulate filter and exhaust gas recirculation system, delivers 42.4kW at 2,000revs/min.

The Sherpa range of mini-loaders and skidsteer loaders from Dutch company Hanenberg Materieel generated a lot of interest with its Sherpa 100 Eco electric mini skidsteer loader. The company says that its noise and emission free machine powered by a 1.5kW electric motor is just as powerful as any combustion engine model. The 760mm wide Sherpa is an ideal tool to consider for indoor demolition applications and a viable alternative to demolition Volvo

robots. The space, which usually contains a combustion engine, is used for a 360A battery pack that keeps the machine going for up to 8h.

Demolition robots The biggest news in the demolition robot sector was the launch of the Avant Robot 185, Avant Tecno’s first robot. The company had been tuning the machine for over a year before its official premiere at Bauma. Decked in the company’s green and red livery, the 2t robot is powered by either an 11kW or 18.5kW electric motor.

When equipped with the telescopic boom, it reaches 5.5m vertically and 4.5m horizontally. The Avant Robot 185 can be fitted with various attachments from breakers to grapples with the maximum weight of 275kg.

Brokk widened its range even further with two more models, the new as well as second smallest Brokk 60 and a diesel version of the Brokk 400.

High-pressure water technologies Finnish Dynaset demonstrated its equipment by using a cross-country motorbike as a power source for its washer HPW200 to wash a car at a neighbouring booth. Equipped with a hydraulic power output, the motorbike turned into a power generator for the washer, thus, proving the point that Dynaset equipment can be successfully installed on any machine, even those without a hydraulic system.

Uraca, a specialist pump and hydrodemolition equipment manufacturer from Germany, premiered a high-pressure cleaning system for concrete truck mixers.

Concrete deposits can eat up about 10% of the mixing drum’s inner volume, which means 2t to 3t of dead weight. The Uraca system consists of a high-pressure pump unit and a lance, which is inserted into the drum to blast away the solid concrete and restore the drum to its original capacity.

Austria is one of the world’s trendsetters in mobile recycling technology. Linz-based Rubble Master presented the track-mounted MTS 2010 stacker, a 20m long machine with a discharge height of 8m for stacking of processed material. Also on display was the RM TWO-GO hybrid technology, combining two drive concepts in one machine. The RM TWO-GO crushers are equipped with a diesel engine drive and an electric motor. The latter represents a cost-saving option for jobs in gravel pits or quarries.

Another major player from Linz, dsb Innocrush, unveiled an innovative drive concept Innodrive that increases recycling performance thanks to direct power transmission. According to the company, this is achieved by excluding all abrasive and maintenance intensive components like clutch linings or viscous couplings. dsb Innocrush specializes in ‘no-frills’ recyclers, boasting very robust and reliable construction and high recycling output.

Oberweis-based SBM used Bauma to expand its Remax series of mobile crushers. The new impact Remax1112 Maxi features a redesigned material flow system, a 1.16m rotor for high-performance crushing and a diesel-electric drive system, ensuring low operating costs.

Crushing and screening buckets Hartl, the pioneer of mobile recycling in Austria, has reinvented itself as a manufacturer of screening and crushing buckets and used Bauma to present their new business to the global construction industry. Hartl crushing and screening buckets represent a lucrative niche market, while permitting the company to use its vast engineering experience in mobile crushing. Its range currently includes eight models comprising four crushers and four screens. The most distinctive feature of Hartl crushers is a special design of the swing jaw plate. Moving along an eight-shape contour, it creates a bigger contact surface than a conventional system, thus, boosting the quality of crushing. This ‘fourfold’ jaw movement, which Hartl has dubbed ‘Quattro’, is Issue 3 • June - July 2013 •

said to result in up to 30% less flaky end product, compared to double jaw movement systems.

Mini-screens were the highlight of another Austrian player, Rockster Recycler. Better known for its track-mounted systems, Rockster decided to shift its focus to compact screens. Its RS EASY

76 is compact, measuring 2.21m in length, 1.51m in width and 2.38m in height, and can be easily transported on a car trailer. The Rockster RS EASY 65 is even smaller weighing only 660kg and has a screening surface of 2x780x1,270mm capable of processing up to 80t/h.

All the new products and methods displayed at this Bauma were linked to four areas: increased efficiency, lower weight and size, increased focus on safety and the environment, and ergonomics. The next Bauma will be held on 11 to 17 April 2016 in Munich.

respectively with wear parts made from 600HB steel. The rotating version has a 360° hydraulic rotation. Both have three jaw configurations to suit different customer requirements.

Arden Equipment’s new universal processor CU031 with patented jaws quick hitch.

French company Arden Equipment exhibited the new CU031 universal processor, scrap shear AS030R and hydraulic concrete pulveriser BBH031 and BBH03R. Arden said that the new processor uses the same patented mechanical quick change system and also weighs the same as the outgoing CU2700 model. However, the CU031 provides 22% greater cutting power, the jaw depth is 19% greater at 800 mm against 670 mm and the jaw opening is 950mm against 809mm.

The new attachment also makes use of a new generation of wear parts that are fabricated from HB500/550 steel, a grade that according to Arden has not been used before on this kind of tool.

The new scrap shear AS030R replaces the AS-027R. Weighing 2.6t the new tool has the same specifications as the model it replaces. However, the new shear features reduced scrap jamming when cutting thin sheets or cables, reduced cycle time, improved steel section cutting, improved mobile jaw guiding, improved durability at the front part of the jaw and easier maintenance and jaw replacement.

Mossville, IL 61552 Country: USA Tel: 1 (309) 675-1000 Fax: Email: cat-industrial@cat.com Website: www.cat.com/industrial-oem Caterpillar Work Tools launched the Cat auto-connect, a new generation of automated hydraulic couplers for hydraulic excavators. Auto-connect fully automates tool exchange, so operators can change work tools in a few seconds from the safety and comfort of their cabs.

Built on the field-proven quick-coupler CW platform, the design of the auto-connect prevents ruptured hoses and oil spills, avoiding unplanned downtime.

“The new auto-connect is based on the same quick-coupler CW platform, which has a European heritage stretching back over 35 years, to help our customers get more out of their machines and work force so they can be more efficient and productive,” said Caterpillar Work Tools engineering supervisor Edward van Amelsfoort. “Also, if the customer already has a dedicated quickcoupler on his excavator he can install the auto-connect without having to do

any changes on the machines.”

The auto-connect has a low height that maintains an optimum breakout force because the geometry between the work tool and the boom is not changed.

It supports up to five hydraulic ports depending on the configuration and application. It is fast, reliable, failsafe and eliminates oil spillages common with manual connections. Its design allows for high flows at low back pressures to ensure tools are used most effectively and to maintain optimum performance.

Auto-connect is a ‘plug-and-perform’ system based on Caterpillar’s CW platform that fits directly to the machine and its existing controls. It is controlled via the quick-coupler actuation circuit. Combined with Cat tool control, it is easy for operators to select tools and make fast changeovers. With features like auto depressurisation as standard, no additional hydraulic components are required.

Genesis introduced Genesis XT mobile shears to process scrap and fit on smaller carriers, reducing initial acquisition investment and hourly energy consumption costs. The GXT features a centre of gravity that is closer to the excavator, enabling the GXT 555 and GXT 665 models to mount on 21t to 30t excavators that previously could only carry smaller, less powerful shears.

GXT features include improved jaw geometry, making it easier to pick up material and reduce ground contact wear. The reverse-mounted hydraulic cylinder shortens shear length and weight, protecting the rod from damage and lower shear height improves visibility.

The Swiss crusher manufacturer Gipo AG launched the tracked cone crusher with screen unit, Gipocone B4 Giga. According to the company, this is a compact, reliable, efficient and versatile cone crusher efficient in reducing particle size. It has three-deck sieving trays.

recyclers

here were several new tracked mobile recycling units at Bauma, although no new manufacturers. The established companies showed improvements and updated versions, but with no new innovative solutions. Heikki Harri reports on some of the latest equipment. PDi’s Heikki Harri reports.

Keestrack Keestack from Belgium is one of the many independent and privately owned companies in the business of tracked recycling equipment. Founded 25 years ago, it specialises in hybrid and other environmentally focused equipment. In 2010 Keestrack acquired the Italian manufacturer OM adding the latter’s knowledge of tracked machines and their jaw crushers to the company’s portfolio.

At Bauma, Keestrack premiered two hybrid machines, the impactor Destroyer 1313 and the electrically driven screening unit Novum, both with the definition Eco-Drive. The Destroyer 1313 weighs 60t has an intake opening of 90 mm by 1,280mm, and a rotor diameter of 1,267mm resulting in a production capacity of up to 400t/h. The electric motor driving the unit has a power of 250kW. The re-circulation conveyor can work in closed circuit or can be used as a stockpile conveyor for oversize product.

Keestrack also displayed a redesigned Apollo jaw crusher unit. Apollo weighs 38t and has a production capacity of over 300t/h accepting up to 600mm feed material. The jaw crusher is equipped with the patented non-stop system to ensure a continuous production

models. The product range is extensive with a large number of stationary models. The company was established in 1965 for manufacturing agricultural equipment, but has since turned into a specialty company for recycling.

The DW series of shredders are designed for processing compost, waste wood and garbage. It includes eight models of which two are on tracks. The DW 2060 K BioPower has a total weight of 20t and is equipped with a Mercedes Benz diesel engine providing a power of 240kW at 2,200revs/min. The roller’s length is 2m, the diameter 600 mm and the number of teeth is 28.

The DW series includes two larger tracked shredders, the DW 3060 K and the DW 3080 K. Both weigh more and have more powerful Mercedes Benz engines.

Small excavators,

big excitement PDi looks at what is new in the mini and compact excavator market. PDi’s Jim Parsons reports.

I

t has been more than half a century since the famed ‘Think Small’ advertising campaign brought the Volkswagon Beetle to the attention of automobile buyers around the world. Since then, the concept has been embraced by a host of other industries, as a counterpoint to the concept that bigger is always better.

In construction and demolition, of course, there will always be a place for large machines that can bring a lot of muscle to tackling large, complex projects. But in an era where everyone, it seems, is being asked to do more with

less, few pieces of equipment have become more important to contractors than mini and compact excavators.

Hardly the cute toys of long-ago incarnations, small excavators are proving that they too can pack quite a punch under far less than ideal conditions, with engines and hydraulic systems capable of producing unprecedented degrees of digging and lifting power. Their small size also enables them to bring that energy and versatility into constrained spaces, inside and outside, thanks to the emergence of zero-tail swing designs.

Though compromises must sometimes be made when it comes to downsizing, it is hard to find any feature absent from a modern mini and compact excavator’s resume. If anything, these machines have taken operator safety and comfort, noise control, and tool compatability to new heights, while bringing fuel consumption and emissions control down to the barest of minimums allowed by new environmental regulations.

So yes, this is a good time to think small and there are a lot for today’s equipment shoppers to think about.

Expanded Kubota excavator line

giving operators the option of an Eco mode for up to 20% less fuel consumption than previous models.

For applications that require full power, operators can switch to standard mode and still experience improved efficiency and lower fuel consumption.

The KX040-4 has a 31kW engine, a dumping height of 3.9m, and a digging depth of 3.4m. The excavator also boasts auto-downshift travel motors, which shift automatically and allow operators to enjoy smooth turns and faster backfilling.

Kubota’s KX040-4 is ideal for contractors looking for 5t features in a 4t machine. Operators get to work in a top-of-the-line deluxe interior that rivals larger models with a spacious air conditioned cab, wide entrance, fully flat floor, deluxe suspension seat, and an easy access upfront control panel. Other features include a Tier IV Kubota engine, an automatic regeneration system, and the popular angle dozer blade option, which speeds up finishing work and features a float function and bolt on cutting edges.

Kubota’s U35-4 tight tail swing compact excavator offers a new class of comfort and luxury in even the most confined spaces. The U35-4 is equipped with the same spacious cab as a larger 5t excavator. The roomy cab features a larger entrance, deluxe suspension seat, air conditioning, easy-open front slide window, ample legroom, new digital panel, and enhanced ergonomics for optimum operator comfort. Powered by a Kubota 18kW

direct injection engine the U35-4 boasts a maximum dumping height of 3.5m and digging depth of 2.9m.

Kubota’s KX018-4 is one of the company’s most versatile compact machines, raising the standard in the 1t to 2t class. The KX018-4 is powered by a Kubota D902 12.5kW engine that meets the latest engine emission regulations without additional equipment.

The KX018-4 has a dumping height and digging depth of 2.4m. Kubota’s KX018-4’s versatility spans from construction, roads and residential projects.

This new compact excavator features a long tumbler distance and wide variable track for increased stability and lifting capacity, a variable track gauge, and autodownshift travel motor for smooth operation. Inside, the KX018-4 offers ample legroom, an adjustable seat, and a new multi-function digital panel positioned for

Kubota Tractor Corporation got 2013 off to a big start, unveiling three new excavator models for the North American market at the January World of Concrete show in Las Vegas. “Upgrade, innovate and expand are three words that describe Kubota’s approach to the construction market in 2013,” said Kubota northern division vice president construction equipment Ted Pederson.

Kubota’s new 4t KX040-4 packs superior per-

formance, versatility, and comfort into one compact machine. Replacing the KX121-3, Kubota’s single most popular model, the KX040-4 prioritises economy and supports the environment with its Eco Plus system,

better visibility.

Kubota construction equipment product manager Keith Rohrbacker, said that the company continues to receive positive feedback regarding its new product introductions. Of particular interest to demolition customers is a diverter valve for single auxiliary hydraulic units, and a dual auxiliary hydraulics option available on all the new excavators. “These customers usually have a hydraulic thumb mounted on their excavators for material handling,” said Rohrbacker. “With our new features they can leave their hydraulic thumb connected, and easily attach a hydraulic breaker for demolition work.

This really speeds attachment changes and improves productivity for our customers.”

radius is also suited to working within a single highway lane, minimising disruption to the flow of traffic. This feature can sometimes be a prequalification condition on contracts.

All three models are available with a mono-boom and ECR88D owners can choose an optional two-piece boom, several arm configurations, and blade for greater flexibility. Thanks to their reinforced, three-piece, high-tensile steel X-shaped frame undercarriage, these mini-excavators are durable and reliable, and readily able to withstand the rigors of demanding work environments. The D-Series also offers a variety of optional quick couplers and a new and extensive range of genuine Volvo attachments.

Quickly positioning the machine is easy, with slew and offset movements controlled simultaneously with a joystick that is precise and effortless to use. Superior hydraulics and pump flow also help provide faster cycle times and better digging performance.

Volvo’s short swing compact excavators When space is in short supply, the new ECR25D, ECR58D, and ECR88D short swing radius compact excavators from Volvo Construction Equipment are in their element in small, enclosed areas. But even with their compact size, the D-Series compact excavators boast class-leading digging depths, breakout and tear out forces, and lifting capabilities that rival their larger counterparts. These machines also feature engines that offer superior performance and reduced fuel consumption.

Getting around site on these compact machines has never been easier thanks to automatic two-speed travel for optimised traction, as well as hydraulic travel pedals for easy and accurate track control. The ECR25D has the added feature of high mobility as it can be transported with up to three buckets and a hydraulic breaker on a small trailer, and still weigh less than 3.5t, including the trailer. Four accessible tie-down points further aid easy and safe transportation.

Featuring a narrow body design and centrally positioned boom, the superstructure on the ECR58D and ECR88D models is so compact that its rear swings within its track shoe, and the ECR25D only exceeds track width when equipped with an additional counterweight. This means that the excavator can get extremely close to objects without risk of collision with the rear of the machine as it swings. But the short front/rear

New engines deliver lower emissions along with superior performance and fuel efficiency. This equates to higher productivity and lower operating costs. The ECR25D is fitted with a 15.5kW engine, while the ECR58D comes with a 4 cylinder Tier 4f engine for North America or a Stage IIIA for Europe and Asia producing 36.5kW. The ECR88D comes with a 4cylinder, 43kW Tier 4f/Stage IIIB engine. The ECR58D and ECR88D feature an exhaust after treatment system for lower emissions and seamless operation, performance and productivity, even during regeneration.

To reduce running costs and fuel consumption, an auto-idling system reduces engine speed when the controls are inactive for a specified time. ECR58D and ECR88D operators can preset the time via the display for between 3s and 20s.

Though small, these D-Series ECR excavators

provide a superior operator experience and a comfortable operator environment naturally delivers higher productivity. The cab, which is standard to the ECR58D and ECR88D, is ROPS certified and features modern styling with all-round visibility provided by a large expanse of flat glass. Comfort is delivered by an adjustable seat, superior vibration and noise insulation, ergonomic armrests, ideally placed controls, and a large floor area for increased foot space.

For extended uptime, D-Series compact excavators are easy to service and maintain. All check and cleaning points are readily accessible at ground level and grouped together under a wide opening lockable hood. Boom and arm greasing points are also easily accessible, and in general applications greasing need only be carried out every 10h to 50h.

Last, but certainly not least Volvo’s optional CareTrack remote telematics system, available on the ECR58D and ECR88D, conducts a self-diagnostic routine, alerting the operator, or the fleet manager, if a fault is detected, in addition to monitoring fuel consumption and when the next service is due. CareTrack on the ECR25D includes geo-fence and geo-tracking, keeping track of engine on/off status, and providing an hourly data report.

Bobcat launches E25 2.5t compact excavator Bobcat has launched the new E25 reduced tail swing compact excavator. Equipped with cab and standard bucket, the new 2.5t E25 offers all the advantages common to the E-Series, such as superior hydraulic performance, smooth and precise workgroup opera-

comfort to the next level by adding an optional debris guard between the work and operator station, making demolition applications an easier task.

This excavator is powered by a 3-cylinder, 9.5kW diesel engine and includes an advanced hydraulic system.

Best in class horsepower make the 803 an excellent solution for difficult excavating and demolition applications. “This excavator has the power to do what others in its class can’t,” said Purcell. “Because of the increased horsepower, larger hydraulic reservoir and hydraulic oil cooler, the 803 is designed to operate a hammer for extended periods.”

Wacker Neuson’s 803 also features a telescopic undercarriage that can extend from 698.5mm to 864mm for greater stability and lifting power. Professional contractors and rental customers will appreciate the simple design of the control panel and its overall ease of operation.

The 803 is also equipped with a pattern control selector for added flexibility. Service and maintenance are also easy by simply opening the large engine cover where all technical components are accessible.

tion, exceptional operator comfort, and high reliability.

Weight distribution in the E25 excavator is optimised through the use of proven ‘4-plate box’ technology to reduce the weight of the workgroup, which moves the centre of gravity of the machine towards the back of the excavator. As a result, the E25 does not require any additional counterweight.

The E25 is powered by a 3-cylinder Kubota D1105-E2B-BCZ-2 diesel engine delivering 15.5kW at 2,400revs/min. A new main hydraulic system control valve and optimised pump combine to create higher working pressure, allowing smooth, quick and simultaneous operations together with powerful digging forces.

The open centre hydraulic system has a dedicated priority section in the main valve that creates a load sensing

Wacker Neuson’s new angle blade

feature, resulting in smooth and controllable feedback of operations. The dedicated gear pump for the pilot controls creates additional hydraulic flow to improve simultaneous operations. Combined with cushioned boom and arm cylinders providing smooth end of stroke movements, the E25 operates as a quieter, more efficient and productive compact excavator. The operator noise level is 77dBA, and bystander noise level is 93dBA. Both the canopy and cab versions of the E25 offer plenty of foot and legroom as part of a comfortable work environment that also includes heating and radio/MP3 ready as standard equipment. Operators enjoy full 360° visibility, and a full view to the right track and to the rear of the cab. The wiper motor is mounted on the lower front window to provide better forward visibility and remove weight from the front window, while the front window cross member section has also been minimised to increase the forward visibility.

Travel controls with new cast aluminium pedals enable smooth, precise control of the E25. When not in use, the pedals can fold forward for maximum foot room and easy cab clean out. The travel levers are positioned adjacent to each other, allowing easy drive control, even with one hand if necessary. This makes it easier to backfill, as the operator can steer with one hand while adjusting the blade with the other.

The control panel is similar to that used across Bobcat’s E-Series, and includes a clear display showing engine speed and working hours. There is an automatic system that switches off work lights after 10min when the key is not in the ignition, preventing the battery from going flat; and a fuel-filling interval alert that indicates level as the tank is being filled.

Boom swing is controlled by a thumbwheel located on the left joystick, instead of the pedal control used on many comparably sized machines. This feature ensures improved metering of the boom swing as well as offering

more floor space for the operator.

Another new feature offered by the E25 is an autoshift travel motor that allows an automatic transition of speeds. The machine shifts automatically from low to high speed and vice versa, providing superb travel performance in all working conditions. The operator activates this feature by simply pushing the button on top of the blade control lever.

Sealed floor plates and insulation on the inside of the engine panel behind the seat protect the operator from undesired heat in the cab. The directional lug rubber tracks enable a smoother ride with less vibration while providing an excellent grip.

Computer-aided design and durable materials and structures contribute to the E25’s reliability and service life. All daily maintenance points are easy to access through the rear tailgate, right-hand side cover, and removable grill and side panels.

Wacker Neuson’s new mini-excavator Wacker Neuson’s new 803 mini excavator is the smallest in the company’s growing line of compact equipment.

At 0.8t and just 698.5mm wide, the 803 is designed for digging and demolition applications in tight spaces, both outdoors and inside. “This mini excavator may be small in size, but it’s big on versatility and performance,” said Wacker Neuson excavator and dumper product manager Adam Purcell, speaking at World of Concrete 2013.

“The new 803 is all about accessibility and power. The narrow width and short height allow this machine to operate in areas with restricted access points, making it very versatile on any jobsite.”

The 803 comes standard with rubber tracks, while the foldable ROPS reduces the machine height for even more accessibility. The unique ROPS design takes user

ker Neuson’s 3503 3.5t compact excavator is now available with an angle blade for backfilling. The 3503 offers one of the smoothest and most powerful hydraulic systems in its class and with the new hydraulic angle blade this compact excavator is even more versatile.

The 3503 with the angle blade option allows the operator to push material to the side of the excavator, making it perfect for backfilling applications. The angle function can be operated up to 25º to the left or right.

The blade can also be lifted 381mm above ground level and 508mm below. Operating the angle blade is by a single lever controlling the vertical and angle blade functions. For added convenience, a marked indicator takes the guesswork out of returning the blade back to its normal working position. “Backfilling with the angle blade is faster and more productive,” said Purcell.

“Backfilling is more precise and can be accomplished in smaller areas with less repositioning because of the ability to position the blade in the direction where the material is needed.”

With a maximum digging depth of 3.2m, the 3503 features one of the smoothest and most powerful hydraulic systems available. A canopy or heated cab option offer both comfort and visibility. The 3503 is available with either a standard or long dipper stick for either maximum digging force or depth. Powered by a Yanmar 4-cylinder, 23.5kW diesel engine, the 3503 is the most powerful unit in its class. Rubber tracks, a dozer blade, boom-mounted lights, and the control pattern selection system are standard.

Gehl offers a full range of compact performance Gehl compact excavators are positioned in the North American market to meet the needs of contractors and agricultural customers. Gehl excavators excel in applications such as grading and excavating, trenching, digging, demolition, and recycling, and light utility construction.

Their compact nature and zero-tail-swing design make them ideal in situations where space is limited.

The new Gehl range consists of five models; the Z17, Z27, Z35, Z45, and Z80. Each is built around a Yanmar engine; Tier IV on the Z17, and Interim Tier IV on the Z27, Z35, Z45, and Z80. The hydraulic system is designed to enhance engine performance, resulting in a more efficient system. These models are zero tail swing machines allowing them to operate directly against a wall or other obstruction.

The hydraulic system incorporates two variable pumps and two gear pumps. The oil flows are combined and redirected to where the flow is needed. This allows for simultaneous operation without loss of hydraulic power. The Z80 excavator has the Eco mode feature, which reduces engine speed by 10% without sacrificing power when activated, saving fuel when full speed is not necessary. The mode is easily activated and deactivated with a simple toggle switch.

The Z27, Z35, Z45, and Z80 are equipped with a hydraulic quick coupler, making attachment changes as simple as flipping a switch. Plus, the universal style coupler works with a wide range of excavator attachments, putting tools already on hand to use. An integrated boom light illuminates the area being excavated.

Rugged, high-strength booms are constructed with a single boom pin design and thick side plates with internally routed hydraulic lines. Heavy-duty cylinder guards protect exposed cylinders from damage. Longer, offset crawler tracks enhance stability and provide smoother travel. Tracks are short pitched to reduce wear, fatigue, and damage. The angled crawler frame reduces soil build-up on the undercarriage.

The large, walk-through operator’s station on canopy units increase operator safety and comfort, and enhance productivity. Easy to remove side covers and a large rear access door allow access to all daily inspection and major maintenance points.

In addition the Z17 is equipped with a variable undercarriage, which extends from 950mm to 1280mm wide. This allows the machine to access narrow areas and provides the ability to increase stability on uneven terrain. The dozer blade expands to the same width for further stability and improved backfill capability.

“The Gehl compact excavator product offering meets the demand we have recognised in the mini excavator market,” says Gehl product manager Nathan Ryan. “This new compact excavator model range suits the reach, dig depth, and lift capacity needs of builders, landscapers, general contractors, plumbers, and excavation crews nationwide.”

Complementing the Gehl excavators is a full line of Edge attachments, including buckets, hammers, breakers, and thumbs.

Yanmar engine for an even more powerful midi-excavator Yanmar of France has been the world’s leading diesel engine manufacturer for more than a century. Since the 1993 launch of its first zero tail swing mini-excavator, the company has looked to improve its products through

54 PDi • Issue 3 • June - July 2013

the integration of the most advanced and innovative technologies. The latest addition is the ViO80-1A, an 8t, zero tail, rubber-track midi excavator fitted with new a Stage 3B engine and cutting-edge equipment.

The new ViO80-1A is equipped with the Yanmar 4TNV98C-WBV engine, delivering 42.4kW at 2,000revs/min and complies with the latest Stage 3B and Tier 4 emission standards. Features include a particulate filter that runs without additives. The filter traps particulates contained in the exhaust gases and burns them off in the course of automatic regeneration, keeping it constantly clean.

The engine’s exhaust gas recirculation system cools a proportion of these gases by mixing them with the intake air in order to lower the oxygen concentration in the air intake. This means a low combustion temperature, reduced NOx emissions, and improved fuel efficiency.

The common rail system and the engine control unit ensure perfect control of the engine operation and a constant exchange of data between the engine and the other components of the midi-excavator, for optimised operations.

For reduced fuel consumption, the ViO80-1A comes with an Eco mode, which controls the engine speed, and an auto deceleration mechanism, which automatically reduces the engine speed when the excavator is not in use.

With 15% faster working cycles than its predecessor, the ViO80-1A offers 18% improved productivity.

As with Yanmar’s other excavators, machine maintenance is simplified thanks to quick and easy access to each component. The ViO80-1A is equipped with a digital dashboard for overseeing smooth operation.

The daily maintenance operations and the frequency of parts changes are also managed and controlled via this dashboard.

Doosan launches new crawler models Doosan Construction Equipment is aiming for an increased share of the 14t to 16t crawler excavator market with its new Stage IIIB-compliant DX140LC-3 and

DX160LC-3 models. Both are powered by the Doosan DL06K common rail 6-cylinder turbocharged diesel engine. The engine delivers 15% more power of 82kW at 1,850revs/min than previous Stage IIIA models. The engine also delivers 11% more torque in the DX160LC-3 model. Factory tests show a reduction of up to 17.5% in fuel consumption, depending on the operating mode selected and the work being undertaken.

An Eco gauge also helps the operator to lower fuel consumption by providing real-time monitoring of fuel rate and engine load. Two new operating modes, Power Plus and Lifting, also improve controllability and efficiency with additional sensors, which further allow operators to optimise management of the engine and hydraulic system.

The drawbar pull has been increased by 5% in the DX140LC-3 model and by 34% in the DX160LC-3 excavator, while swing speed and torque have been increased by up to 12% on both models.

Both models offer a new ROPS and OPG-certified cab, offering more space for the operator and several convenient features such as direct control through the joysticks, which have new proportional thumb wheel switches and integrated buttons to provide precise, proportional control of attachments. All functions can be controlled from the instrument panel as well as via a new jog/shuttle control next to the joystick, a feature exclusive to Doosan excavators.

The cab is pressurised and other standard features include fully automatic climate control, a USB port and storage compartments. A side camera is also available as a safety option.

The new excavators have a more robust undercarriage with reinforced components, including track links, track springs and sprockets. The boom and arm have been strengthened by increasing the metal thickness at critical points, and using reinforced bushings.

Both excavators boast an expanded choice of options. They include a floating boom; an inside cab microphone; a straight travel pedal; an engine coolant heater; a dual pump flow combination for attachments requiring very high hydraulic output and 500mm rubber pads.

The DX140LC-3 excavator is available as standard with a 2.5m width undercarriage. It can be combined with monobloc or optional articulated front working equipment, and different sizes of dozer blade and arm options.

The DX160LC-3 model can be supplied with tracks in either standard 2.8m or narrow 2.5m widths; monobloc or articulated front working equipment; different sizes of dozer blades and arms; and a high track undercarriage for in recycling and demolition.

CP Main-Pin Hydraulic Thumb lends a hand Regardless of size, an excavator does its best work when it is matched with a quality attachment. The CP Main-Pin Hydraulic Thumb by Paladin Attachments acts as the perfect assistant to CP buckets for excavators up to 45t.

It allows for a rotation of up to 140º, allowing users to

PDi 55

pick up large objects or keep the thumb out of the way when it isn’t needed.

The CP Main-Pin Hydraulic Thumb is designed to hold a load securely with individually serrated fingers that grip the material. Reinforced side plates and fingers add strength for picking up most materials, no matter how heavy or abrasive.

Fingers on the CP Main-Pin Hydraulic Thumb are manufactured of T-1 steel, ranging from 16mm up to 38mm. Installation is simple, requiring only the welding of a hydraulic cylinder bracket, then attachment with a few pins and a hydraulic cylinder.

Dynaset increases productivity The Dynaset HG hydraulic generator transforms hydraulic power of a mini excavator into electricity for all AC-powered tools, lights, heating, cooling, welding, and 1 or 3 phase motors.

Once a Dynaset HG is installed on a mini excava-

56 PDi • Issue 3 • June - July 2013

tor, it is always ready to use. “The hydraulic power guarantees availability of electricity anywhere, anytime when a mini-excavator is equipped with Dynaset HG,” said Dynaset sales manager Anni Karppinen. “It allows versatile usage of the machine in various projects.”

The Dynaset HG hydraulic generator runs without an additional engine or fuel, and its maintenance free technology makes it a cost effective choice. Because Dynaset HG is always aboard and ready to use, it saves a lot of working time. The result is a more versatile mini excavator and workers can perform different tasks, such as welding or repairing with electric tools right away.

Because the Dynaset HG is powered by a machine’s hydraulic system, no fuel tank is necessary. It is less than half the size of traditional generator, which guarantees easy installation on a mini excavator. For example, a model HG6, 5kVA hydraulic generator is 210mm wide, 485mm long, and 340mm high, with a weight of only 42kg. Yet, a mini-excavator equipped with HG6, 5kVA can produce enough power for a whole worksite.

For supplying basic electrical needs, there is the model HG3, 5kVA. It is only 190mm wide, 420mm long, and 225mm high, with a weight of just 26kg.

Larger Dynaset HG models generate electricity up to 200kVA. Automatic frequency control regulates frequency exactly to 50Hz or 60Hz, and automatic voltage control maintains steady voltage of 115V, 230V, and 400V, according to the electric load. Dynaset HG includes overload protection, safety earth leakage, and international standard 3 to 5 pole sockets or, alternatively a fuse and a socket box.

Other Dynaset hydraulic equipment can make a mini excavator even more versatile. A Dynaset HPW hydraulic power washer transforms hydraulic power of a machine into high-pressure water. Dynaset HPW models range from 10kW to 200kW, water pressure of 90bar to 1,600bar, and water flow from 20litres/m to 300litres/m.

In the hydraulic compressor arena, Dynaset HK hydraulic piston compressor and HKL hydraulic rotary vane compressor, transform hydraulic power of a machine into compressed air for powering pneumatic tools.

Lissmac unveiled two 400V drill motors with a rated power of 4.6kW and 6.3kW respectively. The new models, which belong to the Lissmac Drill-Jet range, have been designed with operator comfort in mind. On top of familiar features, they also boast an automatic phase-changing system and three-gear transmission. Integrated into the central control unit, the phase changer ensures that the spindle is rotated in the right direction, which relieves the operator of the necessity to check the direction every time. LED indicators show the current load during drilling. A core bit collet features a spindle protection system. A specially designed clip secures the machine in a safe manner.

Deutz and Terex partnered on hybrid technology German Deutz unveiled an excavator complete with a hybrid drive system. It took Deutz, partnered on this project by Terex, about a year to develop the hybrid drive for industrial machinery, consisting of a diesel engine and an electric motor. The target was to reduce CO2 emissions and fuel consumption by 20% to 30%. To achieve this, a compact Deutz diesel engine was modified with a Bosch electric motor. This resulted in an efficient and energy-saving drive system, suitable for a wide range of industrial vehicles. The hybrid engine is designed to operate both as a series and as a parallel system. The power source is a Deutz TCD 6.1 diesel engine with a flange-mounted motor generator, which feeds electric energy into a so-called ‘supercap’ pack acting as an electrical energy storage unit. It provides the electric drive with the power it needs to pivot the vehicle’s upper structure. The electric drive motor feeds current back into the supercap pack when arresting the pivoting manoeuvre. The start-stop function automatically shuts down the engine when the excavator is idle. Re-starting is also automatic, initiated by the motor generator, which also supports the overall system by providing a power boost when the drive system is operating in the peak load range.

Mid-sizers make the n Bauma provides a rare opportunity to gather a wealth of information about a vast array of varied equipment in just one week. But for wall and wire sawing equipment this year’s show was light on news, with most major manufacturers deciding to fine tune their existing systems rather than launch new tools. It was medium size companies with the main news. Andrei Bushmarin reports.

A

s all the key players in the concrete sawing business were congregated in Hall A1 the trends in the industry were clearly apparent. High-frequency technology continues to push hydraulic solutions to the sidelines and most of the freshly launched systems tend to be the highcycle variety. Another visible trend was the increased focus on remotely controlled equipment for sawing, drilling or grinding jobs in contaminated areas, such as nuclear power plants.

Concrete cutting and demolition systems for the nuclear industry are quickly becoming a niche area that warrants consideration.

Braun unveils remotely controlled grinder and extends HF saw range Austria-based Braun is a good example of a company that has prioritised nuclear applications. The main attraction at Bauma was a remotely controlled machine for milling and grinding of walls and ceilings. The new system is capable of performing a wide range of tasks, but its primary purpose is remotely controlled concrete grinding in contaminated zones.

The machine can grind up to 8mm of concrete in a single step, depending on the height of a grinding disc’s segments.

Sennebogen, the company featured in this edition of our regular ‘Movers and Shakers’ column, is full of surprises. For starters, despite its global reach and state-of-the-art machinery, it is still a family-owned enterprise, with the owners intimately involved in every aspect of the business. A further surprise is that the range of machines and attachments it makes goes far beyond a few products it is typically associated with. Andrei Bushmarin reports.

A

t every big construction show there will be Sennebogen machines decked out in their bright green colour scheme. There will be cranes, material handlers, excavators and a whole range of attachments from demolition and sorting grabs to exotic sawn timber and paper roll handlers.

Sennebogen now operates worldwide, runs four manufacturing sites in Germany and Hungary and

employs over a thousand people. Sennebogen started out as a one-man enterprise by Erich Sennebogen back in the early 1950s. He liked to say “there is no such thing as can’t do”, so it is perhaps no wonder that the company has grown considerably to the size it is now.

A rather odorous beginning Erich Sennebogen was just 21 years old when he founded his company in Pilling, Lower Bavaria in 1952.

Sennebogen, like many machine building firms in those days, had its roots in agriculture. The very first machine Erich Sennebogen devised in 1953 was a manure loader.

Two years later, a range of lifting equipment for agricultural applications was built, and from that moment on, lifting devices were always one of Sennebogen’s core interests. It took another two years for the company to develop its first mechanical heavy-duty crawler crane for the construction industry. Business was growing so fast that the company was forced to look for bigger facilities. A new site was found near the small Bavarian town of Straubing. Sennebogen moved there in 1959 and Straubing has remained the company’s headquarters ever since.

The 1960s saw the company go into the excavator business. Serial production of hydraulic excavators began in 1964 and, in 1969, Sennebogen made a break through with the world’s first fully hydraulic duty cycle crawler crane. Boasting the combination winch preselection function, the machine represented a major milestone in crawler crane technology.

Material handling comes to the fore By the early 1970s, Sennebogen had grown into an international player, supplying its machinery all over the world. In 1980, the company developed the hydraulically adjusting articulated boom. This innovation redefined the hydraulic excavator market and remains the global standard in the machine building industry. It was also in the 1980s when material handling began to play an increasingly important role for Sennebogen. In 1986 a line of stationary material handlers, with booms of up to 20m, was developed. The 1990s were a period of rapid expansion and takeovers. In 1991, the production plant for mobile excavators was built on a 160,000m2 site in Wackersdorf, Bavaria. Five years later Sennebogen acquired a plant in Balatonfüred, Hungary and turned it into a production facility for steel and welded components. The same year Sennebogen summoned all its experience in materials handling to create a new range of high-performance machines, known as the green line.

In the last decade, Sennebogen established subsidiaries and sales offices in different corners of the globe. In 2000, a sales and service operation centre was registered in Stanley, North Carolina. In 2007, a similar operation, Sennebogen Middle East, was established in Dubai. Within the next four years, two more subsidiaries were opened in Singapore and St. Petersburg, Russia. In 2008, the company invested over €30M in

the construction of a second plant in Straubing with a total area of 125,000m2. In 2010, Sennebogen used Bauma to announce a new motto ‘Go for Green’.

The slogan referred to Sennebogen’s commitment to developing environmentally-friendly solutions, such as electro-hydraulic drives. On 21 March 2011, Erich Sennebogen, who had founded and steered the company for almost six decades, passed away at the age of 79.

Now the company is run by the second generation of the Sennebogen family, Erich Sennebogen junior and Walter Sennebogen.

Two SENNEBOGEN 683 telescopic cranes help remove parts of the welded truss and plate structure of the Sinntal bridge near Bad Brückenau, Bavaria (top, center, bottom)

Two Sennebogen 683 R-HD cranes take down a bridge Demolition has always been one of Sennebogen’s priorities. The company has a demolition excavator range and cooperates with German LST for attachments.

Sennebogen cranes equipped with wrecking balls still find use on various demolition sites.

Two Sennebogen 683 telescopic cranes are currently assisting in removing parts of the welded truss and plate structure on a bridge demolition project in Bavaria. With a length of 770m and a top height of 44 m, the Sinntal Bridge near Bad Brückenau, is one of the largest autobahn bridges in Germany. Erected in 1967, the girder bridge was replaced with a new structure in 2013. After the new bridge was completed, the steel substructure weighing over 6,200t had to be dismantled and taken away piece by piece.

Pullenreuth-based demolition contractor Plannerer was commissioned to do the job. The dismantling process started with cutting the upper structure with flame torches into pieces weighing up to 16t. The 80t lifting capacity Sennebogen telescopic crane holds the pieces until they are cut free and can be lowered into the valley. To ease the crane driver’s job, radio control is used between the banksman and crane operator. Standing on the edge of the bridge, the banksman can monitor the lowering process without losing sight of the load.

Plannerer chief executive officer Stephan Plannerer said that he is very satisfied with the performance of the Sennebogen 683. Thanks to the powerful crawler travel gear, the crane can move around the job under the load without outriggers.

On this project, Plannerer is using the Sennebogen machines for a variety of tasks. One involves drilling blast holes in the concrete pylons from a special work platform attached to the crane. Once the old bridge has been dynamited, the two Sennebogen crawler cranes, working in tandem, will take away the broken pieces.

Atomized mist blankets dust Originally constructed in 1936, Doyle Drive in San Francisco, USA, is a busy thoroughfare that carries thousands of cars each hour in peak traffic periods. In 1990, it underwent a full seismic evaluation and was determined to have reached the end of its useful service life. Its replacement would be an entirely new Presidio Parkway design, including two short tunnels, a wide landscaped median and transitions to city streets to ease traffic and improve safety.

In the spring of 2010, phase I of the project started, with the construction of a tunnel and detour roadway to divert traffic off Doyle Drive.

Demolition of the old structure began in 2012, involving approximately 1,433m of roadway, including some 150 spans in three structures.

The plan required for the road to be closed for one weekend to demolish the entire length.

“There was only a 57h window to demolish the existing structure and complete construction of the bypass before we had to reopen the roadway to vehicle traffic,” said California DOT resident engineer Andrew Yan. “The structure was divided into four main components, all to be demolished within the same time frame. It was a tall order, but we planned out every detail.”

The takedown required a fleet of 40 pieces of demolition equipment, including 20 hydraulic excavators fitted with a variety of tools, such as hammers, grapples, pulverisers and shears.

Crews also used backhoe loaders, track loaders, wheeled loaders and articulated dump trucks, all running continuously to meet the tight deadline.

Because of its proximity to the Presidio, an historic national park that remained open to the public during demolition, the contract called for a dust control plan to prevent all visible dust from leaving the project boundaries while work was underway. “In some places, the public areas were less than 30m away from the demolition activity,” said Yan. “There’s also a residential neighbourhood and business corridor adjacent to Doyle Drive. In addition, we had to consider the nearby marsh, wetlands and forest, as well as the wildlife within those habitats.”

With dust suppression such a high priority, CalTrans researched a number of equipment options to supplement traditional water trucks and manual spraying. “Because we had simultaneous demolition in four distinct locations on this project,

we needed dust control over a very wide area,” said Yan. “But the manpower we could commit to that was limited. The initial equipment designs we reviewed didn’t convince us that they could deliver the coverage we required.”

Yan remembered that another CalTrans project faced similar dust suppression issues, on the Oakland Bay Bridge West Approach in San Francisco. He knew that engineers had successfully controlled the demolition dust on that job with large atomized misting units from Dust Control Technology. After reviewing specifications on the various models and discussing the project requirements with DCT, he arranged a rental of eight DustBoss DB-60s, with on-site training supplied by the manufacturer.

tion project, while protecting the surrounding communities and natural environment. “I was particularly impressed by the range of the unit, and the relatively low noise level during operation,” said Yan. “The ability to easily mobilise and relocate the units as needed was also a big advantage on this job.” In addition, effective suppression minimized the opportunity for abrasive dust to enter air intakes on heavy equipment, extending air filter life and reducing the potential for unnecessary wear.

“This was a very high-profile job,” said Yan. “Our goal was to take all practical measures, using the best technology available, to mitigate the demolition dust and safeguard people, property and the environment. I would recommend the DustBoss on future contracts of this type.”

Atlas Copco HB 4100 breaker in underwater demolition When completed, the new parkway will reveal striking views of the Presidio and San Francisco Bay. One of the best-known designs in the DustBoss product family, the DB-60 is a large-scale suppression unit with special atomizing nozzles that create an engineered mist, sizing the droplets specifically for optimum dust control, which is typically 50-200microns. A 19kW fan launches the droplets over long distances, allowing one full oscillation machine to cover nearly 11,600m2 with a dust-trapping mist.

In California DOT work sites, dust control is no longer a luxury but a contractually mandated component of demolition, construction and certain types of maintenance work, subject to inspection. “Particularly in the city and greater San Francisco Bay area, dust suppression strategies and techniques are constantly being reviewed and refined,” said Yan. “Overall, there’s been an increasing focus and scrutiny on developing multi-pronged approaches to site maintenance, including dust management and water pollution prevention.”

With the significant reduction in airborne dust, Yan and his crews contributed to a healthier workplace on the complex Doyle Drive demoli-

The Presidio remained open to the public during demolition, so the contract called for a control plan to prevent dust from leaving the project boundaries.

Since August 2012 an Atlas Copco HB 4100 hydraulic breaker has been in use for underwater demolition near Giglio Island, Tuscany, Italy. The work is the first phase of a major maritime engineering operation in which Atlas Copco is closely collaborating with the Italian construction company Sales specialising in infrastructure and maritime projects.

For underwater demolition of granite at a depth of 10m, Sales is using a 4.15t Atlas Copco HB 4100 breaker attached to a Liebherr 984 tracked excavator mounted on a floating pontoon.

Working blind in the cabin of the excavator, the operator relies exclusively on a GPS tracking system and instructions from divers.

D-Drill assists in Abbey restoration In the UK concrete cutting specialist D-Drill, was part of the team that completed the first phase of a £6.5M (€7.6M) restoration project at Torre Abbey in Torquay.

The 12th century building, the oldest in Torquay, has been deteriorating since the 1840s but a project, which has benefitted from a £4.9M (€5.7M) Heritage Lottery Fund grant, began in 2005 to return it to its former glory and make it a much more accessible visitor attraction.

D-Drill was contracted by Kier Western to remove a reinforced concrete floor over three levels and also to remove two concrete supports holding tombstones dating back to the 1100s. In ordinary circumstances, the firm would have used a robotic demolition machine to break through the concrete but that would have potentially damaged the building because of vibration.

D-Drill at work on the 12th century Torre Abbey.

Atlas Copco’s HB 4100 working on a demolition site underwater.

To enable the HB 4100 to operate underwater it is partnered with an Atlas Copco XAHS186 compressor. The compressor prevents water from entering the machine by blowing in compressed air. Channels for compressed air are standard on Atlas Copco hydraulic breakers, enabling them to be used underwater. A safety system immediately stops the stroke of the hammer if, for any reason, the compressor stops injecting compressed air.

Atlas Copco hydraulic breaker product manager Gordon Hambach points out that the company has extensive experience of dredging, excavation and underwater demolition in harbours, rivers, and canals. “We are working on

So the team devised a plan to cut out sections of the floor piece by piece in order to make sure no damage was caused to the abbey.

“When it comes to breaking up the amount of concrete required here, we would normally use a Brokk robotic demolition machine, but we had to adapt to the building and went for an alternative method,” said D-Drill branch manager Ed Taylor.

The three-day task saw over 70m2 of 200mm deep concrete slabs removed. Cutting the concrete also lead to high temperatures and water was used as a coolant, but no liquid could be allowed outside of the work area for fear it may contaminate the tomb areas. “Allowing water to run off was simply not an option as there were monks buried in the floor beneath us,” said Taylor.

“We were also surrounded by historic ruins, artefacts and also newly renovated rooms, so it was absolutely vital that water couldn’t escape.”

D-Drill used technology devised by Austrian company Golz to filter the water and the waste and turn it into a jelly-like substance that could be disposed of off-site.

IACDS: An Ominous In April the International Association of Concrete Sawers and Drillers (IACDS) held its annual meeting in Munich, Germany at the trade show Bauma. IACDS organised a day of seminars and announced the winners of the 2013 IACDS Diamond Awards. At the meeting the national member association for Austria announced that it would like to leave IACDS, as it questioned the value of being a member.

The decision cast a shadow over the entire meeting. PDi’s Jan Hermansson reports.

Successful seminars but poor attendance

On 22 April IACDS held its annual conference in conjunction with Bauma. Traditionally, IACDS also stages a day of technical seminars, followed by the IACDS Diamond Award ceremony and cocktail party.

Bauma was a big success, attracting a record number of visitors to view and test the many new products on display. Maybe that is why some of the IACDS seminars did not attract the number of participants anticipated.

Nevertheless, the seminars were very interesting and raised a number of important subjects for concrete cutters. The first presentation was on “Drilling with high speed compared to drilling with conventional speed” given by Marie Peil from Pentruder. The second presentation was titled “Metal cutting with wire saws”

by Alfred Landl from Tyrolit. Hilti’s Ernest Siegenthaler spoke about “Technologies to make your cutting and coring business more profitable”. Lars Gustafsson from Husqvarna Construction Products gave his presentation on “The importance of working environment in the industry”. Next speech was titled “Ground penetrating radar, a business opportunity beyond diamond sawing and coring”, and was given by Hilti’s Julia Zanona. The seminary programme ended with a talk from Tyrolit’s John Willis titled “Grinding and grooving of concrete roads”.

IACDS Diamond Awards and cocktails

After the seminars the winners of the 2013 IACDS Diamond Award were announced. Twelve contractors entered and each contribution can be viewed at the website www.iacds.org. At the award ceremony only the three winners’ contributions were displayed. First prize went to the Spanish contractor Talls, Forats y Ancorat-

66 PDi • Issue 3 • June - July 2013

ges, in Xirivella, Valencia, for their under water diamond wire sawing project. The contractor made an extension of the eastern dock in the port of Castellón, Valencia, making 99 holes with an opening of 2.5m x 5m x 0.5m on the side of the drawers that form the dock. Second prize, also to Spain, went to Thayr in Madrid, also for an underwater job where four provisional piers of the A44 motorway Guadalfeo viaduct were demolished. A diamond wire technique was used cutting each pier at a level of 20m below the water level, and sinking the piers in the reservoir. Third prize went to the concrete cutting company Marutatsu Road in Japan with head office located in Tokyo. The project consisted of the removal of a concrete slab from an existing bridge and extreme caution was required during the concrete sawing and drilling.

The award ceremony ended with a cocktail party where contractors and suppliers from all over the world had the chance to exchange knowledge and experience.

A drastic turn

On the Monday after Bauma, forty IACDS delegates gathered for their annual meeting at the Ashat hotel on the south side of Munich. The day started with the outgoing IACDS president José Blanco welcoming everybody. The protocol from the 2012 annual meeting in Maui, Hawaii was approved and Blanco continued with his annual report. One new member was elected to the IACDS, which was the new Russian Concrete Sawing and Drilling Association headed by Andrey Kossolapov.

Russia has struggled to set up a national association and Kossolapov was very happy it has been formed. The Russian association has initiated cooperation with the German association and a contract was signed on the day.

Meeting in Munich Werner Havlena reads a letter sent from the Austrian association indicating that their national association will be leaving IACDS.

“The Russian association already has thirty members, containing twenty-five contractors and five suppliers.

But we have a great potential to grow fast as there are many concrete cutters in Russian and the market situation looks good,” said Kossolapov. There are about 400 professional concrete sawing and drilling contractors in Russia and about 90 supplying companies.

IACDS has ten association members as Austria, through its delegate Werner Havlena, asked to leave the association. Havlena read a letter sent from the Austrian association expressing that their national association did not have any interest in continuing its membership in IACDS. After Werner Havlena’s revelation the meeting

discussed the situation and the future for IACDS. The fact that the Austrian association is leaving IACDS raised a lot of questions. Some delegates expressed that the activity and the outcome of IACDS’ work had been criticised before. José Blanco stressed that IACDS’ task must be to lead this industry into the future. To be ahead of the industry itself has always been the aim.

If the international association is going in the wrong direction it is important to improve the communication with the national associations in order to find out what they want from IACDS. At the meeting one of the suppliers’ representatives, Donat Fritsch directed a question to the contractors: “What do you want from IACDS?” Anders Andersson from the Swedish concrete sawing and drilling contractor VOID said, “I want to learn how to make more money. I want IACDS to help the national associations to help their members to work better, more efficiently, to more easily adapt to new methods, to become safer and more competitive, to learn how to interact with other similar contractors and to broaden our field of expertise in terms of methods and geographically. We live in a modern society and we, as many other industry sectors, need to develop not only in our home country but to other markets, too. That is where IACDS has an important task to fill.”

The German association president Thomas Springer proposed that IACDS call a meeting with the national associations to discuss the future of IACDS. The participating delegates agreed and a preliminary meeting will be held some time in October in Amsterdam.

The meeting proceeded with the membership report, the annual accounts, financial report and budget held by IACDS secretary Daniel Trachsel. He also led the

discussions and reflections about the IACDS seminars and Diamond Awards. Plans for the next seminar sessions were discussed as well as the next Diamond Award.

The point was raised that maybe IACDS should try to set up a programme for certification, like a drivers licence for concrete cutters, which could then be adopted by the different member nations. Clear benefits would be that knowledge and skills could be improved as well as improving the status for concrete cutters. It would also in the long run eliminate rouge players. The idea was widely welcomed by the delegates and a group within the IACDS will look into the question about a certification programme.

This was followed by Andrey Kossolapov describing an interesting project in Moscow. A new technology of tunnel construction through solid rock in special conditions was used in an underground construction project.

Interesting reports from the markets The country reports are a popular and interesting element at the annual IACDS meetings. Donat Fritsch from Switzerland reported that the situation in Switzerland is very good. The construction sector is booming and the currency is strong. The association has 84 members. About ten to twelve new and trained concrete cutters leave the apprenticeship programme every year organised by the association.

The German association’s Thomas Springer reported that they have 710 members where 637 are contractors.

There are about 1,200 concrete cutters in Germany. The average turnover is about €534,000. This means that Germany continues to have the world’s largest concrete sawing and drilling association.

Verner Havlena from Austria reported that the Issue 3 • June - July 2013 •

Delegates at the IACDS Diamond Awards

Austrian market has grown by about 10% since the last meeting to an average turnover per contractor of €670,000. The situation is good and stable. There are 36 members in the association and about 140 concrete cutters in the country.

The new IACDS member, Russia, reported that the average turnover for a Russian concrete cutter is about €457,000/year. The association has their own training programme for workers and company owners. The Russian association has their own tolerance rules, but is also using the norms set up IACDS. The market situation is good and stable now and also for the near future.

Joel Vinsant from the UK sawing and drilling association said that the UK market is picking up again, but only in the last two months. The UK construction economy is a roller coaster, but it now it seems like many of the large projects that have been held back are going to start. The association has 77 members but there are about 250 concrete cutters throughout the UK. Average turn over is about €686,000/year. Vinsant also said that next year the association would celebrate its 30th anniversary. Every year they have their own show called the Concrete Show attracting some 4,500 visitors.

The UK association has their own training programme and their own training area. Health and safety is the priority and 148 apprentices have passed the programme and another 56 are well on their way to passing. The programme is governmentally supported with some €12,000. All apprentices that pass get their own licence and diploma. The programme has become quite powerful as the majority of contractors that hire

concrete cutters only hire cutters that are licensed.

Norikazu Shibuya from the Japanese association reported that Japan has had a difficult time due to the tsunami that stuck the country. The government is economically supporting concrete sawing and drilling companies to help build up the areas of the country that were damaged. Between 2011 and 2012 the concrete cutting industry increased by some 10%. There are several tunnelling renovation projects going on in Japan at present. Shibuya says that the association has about 90 members, but there are around 1,000 concrete cutting firms in the country. The average turnover is €915,000.

Shibuya brought 14 concrete cutters with him to Bauma and the IACDS meeting. He also mentioned that neighbouring Korea has an estimated 700 concrete sawing and drilling firms, but no association.

The US concrete sawing and drilling association executive director Pat O’Brien reported that the market has been rather quiet during the first quarter of this year, but in total 2013 is expected to be similar to 2012. The US association has 476 members and about 322 of these are concrete cutters. There are close to 2,000 concrete cutters in the whole country. Many Canadian concrete cutting firms are members of the US association, as they do not have their own any association. Canada has about 30 members and there are some 300 firms in the whole country. The US association has close cooperation with several other branch associations like the demolition association for instance.

For Spain, José Blanco reports, that the market is close to zero. The construction industry in total is estimated 10% of what it was in 2008. In 2014 many think it will be even worse. Number of member companies in the association has dropped from 80 to only 10.

New elections and the future

Lars Sandström from the Swedish association reported that the situation in 2012 is slightly weaker than 2011.

This year started slowly but picked up in April. The autumn is believed to be more stable and larger projects that are on hold will start up again. The number of members in the association is 102 and there are some 350 concrete cutting firms in the country. Average turnover is about €839,000/year. The Swedish association it taking part in the specialist show for concrete cutting equipment DEMCON, held every second year. Next show will be 4-5 September 2014.

A new president was also elected at the annual

German association management (from the left) president Thomas Springer with the secretariats Anne Paulus and Hans-George Wagener

meeting. Outgoing president José Blanco was thanked for his professional and dedicated work. New president Lars Sandström was elected after being vice president for the last period. Norikazu Shibuya was re-elected as vice president and second vice president elected. Julie White from UK firm D-Drill was also elected and the first time a women has been on the ICADS board.

This year’s IACDS meeting was clouded by Austria’s decision to leave the association, which was taken as a criticism of the umbrella association not performing to expectations. It will be interesting to see the continuation and what in particular happens at the meeting between the member nations in Amsterdam in October.

In some way it may be a surprise that Austria has taken this action, as we live in a time when our world is shrinking, but growing in terms of market potential, whereby industry players can take on jobs across nation boarders, resulting in stronger competition.

Austria’s action is an important warning and may be a start to a completely new direction for IACDS. Perhaps it will take the umbrella association to a completely new level. In some way it is a waste of resources for each national association developing its own training programmes, various standards and accreditation systems. This industry has grown to something very big and will keep growing.

We live in a time when intercontinental networking plays an important role in many industry sectors.

It should also apply to the concrete sawing and drilling industry. But if IACDS has not fulfilled its duties it is very important that everything is brought up for discussion. IACDS only meets once a year and has currently no international project going on, such as the international tolerance standards agreed upon some years ago.

Maybe what is needed is an international organisation with regular meetings, working groups and committees headed by a staffed secretariat.

Keltbray in The Prince’s Trust

In the UK Keltbray, which specialises in construction and decommissioning services, has signed a three year partnership with The Prince’s Trust to help disadvantaged young people turn their lives around through the Trust’s ‘Get into Construction’ programme.

About one in five young people In the UK are not in work, education or training and The Prince’s Trust has a good track record in that three in four of the young people they support move into work, education or training.

One of those people is 20 year old Paul Reilly who now works for Keltbray. After struggling to find employment after losing his job as a sales assistant, he signed up for the Trust’s ‘Get into Plant Mechanics’ course. Following his completion, Paul was interviewed by Keltbray and offered an apprenticeship as a mechanical fitter.

He is based in Keltbray’s plant division at Bedfont, and the company is now sponsoring him to do a three-year NVQ in plant maintenance.

Keltbray Group chief executive, Brendan Kerr, who also started his career as an apprentice, is a great supporter of apprenticeships and training, to the extent that the company has one apprentice or intern to every 18 employees across the Group. “Just like my life was changed, I believe other people’s lives can be transformed by being given opportunities through practical training and work. The Prince’s Trust supports this philosophy and gets young people into work, education and training with the help of employers like ourselves.

Paul Reilly is a shining example of this, and he is now well positioned for a future in our industry,” said Kerr.

Big screen biomass production for GP Green Recycling

In Scotland, GP Green Recycling is probably one of the largest producers of biomass from waste in the country generating around 1,800m3/week from their facilities in Blantyre. GP has continually invested in recycling plant and machinery, which it has sourced from Blue Machinery Scotland for many years and the latest additions are Doppstadt SM trommel screeners, for which Blue is an appointed distributor.

The ever-increasing scale of the GP operation has necessitated additional production capacity

customer,” said Brokk managing director Martin Krupicka.“ I am convinced this machine will continue to triumph within the tunnelling industry all over the world.”

www.brokk.com

War memorial’s new resting place and owner Jim Gilchrist called in Blue Machinery Scotland who recommended changing from a flatbed screener to a trommel drum-screen for screening material to the various different sizings required. A materials handler feeds the incoming waste into a slow speed pre-shredder, which discharges into a Doppstadt AK-435 mobile shredder. This then feeds the reduced size shredded material into the first of two new Doppstadt SM-620 trommels, which are equipped with two screen sizes to produce and stockpile 10mm compost material. This, in turn, feeds the oversize to the second SM-620 with an 80mm drum screen where 10mm-80mm is screened off for biomass, with any oversize being recirculated for further processing.

The Doppstadt SM-620 trommel features the screening drum construction. Replaceable screens, a variety of ancillary equipment and a wide choice of mesh sizes allow the machine to be easily adjusted and reconfigured for the wide variety of screening tasks and feed materials encountered in the GP Green Recycling operation. The trommel screen drum is 6m in length with a 2m diameter and a rotating speed of up to15revs/min.

“We enjoy an excellent and mutually beneficial partnership with Blue Machinery Scotland and can count ourselves as being very satisfied customers for many years,” said GP owner Jim Gilchrist. “Their advice and expertise, coupled with the ready availability of the superb Doppstadt range, makes our choice of machines and supplier all the easier. We are delighted with the two new trommels which have transformed our operations both in terms of volume and endproduct quality”.

Volvo helps with soil cleaning

In Bavaria, Germany one local company is using bioremediation techniques to clean contaminated soil organically. Boden recycling Allgäu (Borag), a subsidiary of Hubert Schmid Recycling, had the first soil bioremediation plant in south Germany.

Borag cleans the contaminated soil and stones, while sister-company, Hubert Schmid Recycling, washes the soil that has been contaminated by inorganic pollutants. Borag excavates the contaminated soil from sites using its Volvo loaders for transport to the treatment plant where micro-organisms are mixed with the soil to break down the hydrocarbons.

Brokk solution for Hong Kong tunnelling

The Hong Kong contractor Modern Concrete Drill Cut Company chose a Brokk 800 remotely controlled demolition robot equipped with a breaker for use on its South Island Line (East) tunnelling project in Hong Kong.

The very densely populated Hong Kong area calls for clever logistic solutions and the public transportation network is constantly being extended. The South Island Line (East) is a new medium capacity 7km long railway that will be almost completely underground. At the north end of the line the existing Admiralty station will be updated with two new underground platforms for passenger interchange with other lines. This is where the Brokk 800 is operating to create a 30m long adit.

A drilling jumbo first drilled holes into the bedrock ready for inserting hand held splitters to break the material. This was followed by the Brokk 800 equipped with an Atlas Copco SB1200 breaker for final excavation. “Our intention was to clear out around 1.5m/day, but we soon realised that this fantastic machine has even better capacity,” said Wong. “I couldn’t think of a better method for this task of combining the enormous capacity with all the normal Brokk advantages, such as electrically driven and remote control.”

“During this project the Brokk 800 has been put to the test and we are so pleased to receive this testimony from an esteemed and experienced

Ninety-nine years after its erection as a memorial to South African combatants killed in World War One, the Cape Town Cenotaph poses a challenge for South Africa’s cutting and relocation industry to give it a new resting place.

The City’s Council has called for tenders for its uplifting and moving to another location to make way for a new bus route on its existing site in Adderley Street. The move might only be a few hundred metres, but local history, military and heritage detractors put up a fight against its relocation as its current location is exactly where soldiers gathered before being shipped off to the battlefields of Europe between 1914 and 1918, South Africa’s contribution to the British Empire.

The Cenotaph comprises a woman with an arm outstretched, sided by statues of soldiers in the First and Second World Wars, as the Cenotaph is now in remembrance of combatants in all conflicts in which South Africans died whilst in service.

Since 1924, it has been the focal point of the annual Armistice Day remembrance activities in the city, which are held on the nearest Sunday to the day when the guns fell silent at 11am on the 11th day of the 11th month in 1918. The armistice between the Allies and Germany, signed at Compiègne, France, led to the cessation of hostilities on the Western Front. Relocation of the Cenotaph is planned before November this year.

CSDA Convention Gives Attendees Key to the Future In the US, a presentation by Seth Mattison, a nationally recognised expert on bridging the generations, was given at the Concrete Sawing and Drilling Association’s 41st Annual Convention and Tech Fair, held between 26 February and 2 March in Florida.

Almost 200 people attended CSDA’s flagship event to jumpstart their new year with fresh ideas and strategies. The main focus of this year’s convention was the next generation of industry leaders, who are the key to the future. Seth Mattison focused on the importance of bridging the generational gap and explained how doing so can lead to greater productivity, creativity and worker satisfaction.

Ten business sessions were held, including Methods to Reduce Water Usage and Slurry Pickup as well as Job Costing Analysis and Estimating, Managing and Executing Successful Polishing Projects.

The convention theme was driven by the CSDA Next Generation Committee, who scheduled two roundtable discussions entitled “If I Knew Then What I Know Now” and “So You Think You Want to Buy the Company.” These roundtables brought together business owners, young and old, to discuss key aspects of business succession and sharing important lessons learned from many years of experience.

NDA elects new president The National Demolition Association has elected new members to its Executive Committee as well as several new members to its Board of Directors.

First-time convention delegate Ed Lounsberry of Exco in Bensalem, Pennsylvania, was impressed with the sessions. “It was our first time at a CSDA convention. We met a lot of knowledgeable people with great ideas, and hope to be back next year. The programmes were timely for us and the content was right on,” said Lounsberry.

In addition to business sessions, networking opportunities and social events, the ever-popular CSDA Tech Fair had 23 exhibitors.

Visitors had the chance to talk with manufacturers in an intimate setting, something that often cannot be achieved at large trade shows.

Even before the official start of the Convention and Tech Fair, the association showed how it is ready for the challenges of the next generation. In line with the introduction of the Imaging Contractor and Polishing Contractor membership categories in 2012, committees were formed and members met for the first time at the Florida convention.

While the main focus was the future of the industry, time was taken to acknowledge the hard work and dedication of those who have helped shape it. The CSDA Lifetime Achievement Award was presented to past president Steve Garrison of Hilti for his outstanding contribution to the association. Garrison has been involved in the industry for over 30 years and continues to be an active member of the association, serving on the current Board of Directors. Outgoing CSDA president, Jim Dvoratchek of Hard Rock Concrete Cutters presented the award to Garrison, who becomes only the fifth person to receive the award.

National Demolition Association Asks for Bigger Role in Disaster Response Armed with the types of equipment and trained employees needed to respond to an emergency, demolition contractors should be prequalified by local governments and agencies to speed immediate and effective response, group said.

Demolition contractors can strengthen government’s response to natural and man-made disasters by getting highly involved during the planning stages for emergencies, not after the tragedies occur, said Jeff Kroeker, President of the National Demolition Association at its annual convention in San Diego this spring.

Kroeker’s comments followed a compelling presentation by three demolition professionals who were at ground zero in Christchurch, New Zealand, following a magnitude-6.3 quake in 2011.

Since Christchurch is the country’s second largest metropolitan area, the experiences of the demolition experts and the city’s leadership can provide valuable lessons to others responsible for emergency management, especially in earthquake-prone areas.

John Weber, former president of Iconco/LVI Demolition Ser-

vices in Oakland, CA – who travelled to Christchurch to handle the disaster response – described the “immense and widespread” damage the quake did to the large city.

Peter Ward, president of Ward Demolition Ltd. headquartered in Auckland, NZ, focused on how conventional demolition means were used to take down several damaged structures, including a 26-story hotel.

The presentation showed the damage of the city, comparing the damage to other quakes and earthquake zones here in the United States, including greater Los Angeles, the San Francisco Bay area, and potentially even Seattle.

The National Demolition Association is intent on alerting communities in the United States that may be unprepared for a Christchurch-like event, said Michael R. Taylor CAE, Executive Director of the association. To this end, the association has formed a Disaster Response Committee, which has prepared a Disaster Response Manpower and Equipment Survey for local and state governments to use to help them prepare in advance to help save lives, facilitate faster response, and avoid the consequences of delayed decision making. The survey is available on the association website in its new Disaster Response section.

“The U.S. Geological Survey,, the science organization of the U.S. government, has predicted with a 99% certainty that there will be a similar magnitude earthquake in California in the next 30 years,” said Taylor. “Our Committee, including those experts who have been working in Christchurch for the last two years dealing with everything from downed utilities, lack of food, housing, and power, hazardous materials disposal, and the safe demolition of damaged structures can share some invaluable lessons with other communities needing assistance with disaster planning.”
