A complete new development of impact mechanism minimizes the discharge of vibration to the excavator, as well reduces the operators vibration stress drastically. In relation with this new developed breaker body, the fully closed frame with rubber plugged service points and a new worldwide patented rod arrangement, gives a considerable reduction in noise levels of 7db. Because of FRD optimized the applied materials with a new hardness process, a higher efficiency at same operation weight is guaranteed.

Chicago Pneumatic’s new German dealer Chicago Pneumatic Construction Equipment has added HTI Collin & Schulten to their expanding dealer network in Germany. A full service civil engineering and industrial technology firm, the HTI Group offers a full range of products and solutions in the areas of waste disposal, landscaping, sewage treatment, storm water management, industrial and building services, electrical, telecommunications, renewable energy, and road and construction machinery, equipment, and tools.

Partnering with only the best quality manufacturers, the HTI Group offers a complete range of hand tools, electrical tools, machines, core drilling equipment, cleaning equipment, workshop equipment, protective clothing and other tools and equipment for the construction market. Machinery, tools and equipment can be rented or purchased directly from HTI. HTI will carry the full line of CP construction tools and equipment, including a wide range of hydraulic and pneumatic handheld equipment, compaction equipment, rig-mounted attachments, portable compressors, and a complete line of parts and accessories.
Best results ever for HTC Group In Sweden the HTC Group has recorded its best ever first half year results in the first six months of 2012 continuing the positive trend from 2011. Turnover during the first half of 2012 was SEK185.8M, an increase of 12% compared with the previous year. Order intake was SEK192.5M, an increase of 14% compared with SEK169.3M the previous year. The increase in turnover growth has led to a very strong earnings performance, where earnings before interest and tax has more than tripled to SEK17.6M from SEK3.8M. The half-year result before tax was SEK12.3M, a margin of 6.6%. The company’s gross margins have been strengthened and the result and profit margin improved significantly through the increased turnover. A continued focus on working capital has resulted in a decrease during the first half of 2012, which therefore has improved the operating cash flow. All product groups experienced positive sales growth compared to 2011 and the demand for the company’s solutions and systems increased and gained market shares from competitive traditional methods for floor preparation and cleaning. The main product group with the strongest percentage growth is dust extractors, where a number of new models have been recently launched. The main contributor to revenue growth is primarily the Black Line, the conventional machine range. The product group for daily chemical-free floor
cleaning and periodic maintenance, Twister, is the Group’s fastest growing and continues to grow by double digits. A continued focus on developing new and improved products with a strong customer demand enables HTC to continue leading and developing the flooring industry. HTC has refined the product range of diamond impregnated cleaning pads for chemical-free cleaning, which is sold under the brand name Twister with more variations customized for particular floor care programmes. In hardware the new dust extractors have been launched with very good outcomes and in the near future, more products in all product groups will be launched, which will enhance the competitiveness of grinding as a method from both a cost and efficiency point of view. In addition, there are a number of applications where new methods are under development. To increase focus in the different areas where HTC is active, the business area Twister was turned into two separate companies at the start of the year, HTC Cleaning Technology in Sweden and Twister in USA. During the current year, significant investment has also been made to improve the efficiency and quality assurance and to improve the production capacity in the Twister area.
New managing director for Pectel In the UK Pectel, the specialist Basildon based asbestos remediation division of Keltbray Group, has appointed Darren Wickins as managing director with immediate effect, replacing former managing director Tim Smith. Wickins has more than 18 years experience in the specialist environmental support services sector, specialising in asbestos management. He joins Pectel from Silverdell, where he was estimating director. His previous experience includes working for Clifford Devlin and Keltbray. Wickins also has experience in delivering £50M plus contracts in the defence, banking, transport, nuclear, leisure and public sectors for clients including Skanska, Bovis & Lend Lease, Sir Robert McAlpine, Land Securities, Mace, Costain and Carillion. “We’re pleased Darren has decided to return to Keltbray to develop the Pectel business and bring a strategic approach to new markets and help unlock areas outside of our existing commercial streams for revenue generation,” says Keltbray Group Managing Director, John Price. “Darren has a results-driven track record within this sector, and we’re delighted to have him on board.”

situation and like everyone else, we do not have the exclusive on this, life goes on, and that includes the demolition industry. The economy slow motion movement is also affecting the demolition industry in many ways with fewer jobs, pricing wars, smaller projects and fewer resources to do the work as best as possible. In this situation, our companies need to be very flexible to adapt to the work available and yet keep working on innovation.

New JCB Iphone App The UK manufacturer JCB Attachments has launched a work tool app for the iPhone, making it easier for customers to locate, choose and purchase the right attachments for their JCB machines. The free download incorporates a dealer locator, an attachment finder by machine type or product group, a Light Equipment viewer and an enquiry function that will send a message directly to the customer’s preferred JCB dealer. Customers can search for any attachment for a specific JCB machine, or look for the correct machine to power the desired attachment. In either case the JCB app takes customers through the straightforward selection process, with pictures of the machines and attachments along with product specifications and features. With the Light Equipment range, that includes hand-held breakers, pumps, earth drills, compaction plates and hydraulic power packs, the process is the same, allowing customers to search for individual tools, providing working weights and operating parameters in clear, easy to read pages with individual photography and specifications. “The demand is huge and allows our customers and our dealers to easily identify the required attachments from our entire range,” says JCB Attachments general manager Cameron Burnett. Third party suppliers can apply to JCB Attachments to have their work tools included on the app. If customers click through to the third party, the sales transaction moves to that company, away from the JCB dealer. “This offers an additional solution to our customers through a third party reference,” says Burnett. The content of the app will be updated every five days, ensuring that the very latest equipment is available to customers. Initially the app will be available in English to customers in the UK and Ireland. However, it is intended that this will be developed for additional territories in the future. The JCB Attachments app is available now as a free download from the iTunes store.
International Equipment Solutions acquires CWS Industries In the US International Equipment Solutions has acquired, through an indirect, wholly owned subsidiary, CWS Industries. This is the fourth acquisition by IES since its formation and financial terms of the transaction were not disclosed. IES was formed in September 2011 as a platform for investments serving the construction, agriculture, landscaping, infrastructure, recycling, demolition, mining, and energy industries.
In the UK the engineering, construction, decommissioning and environmental services provider Keltbray Group, has recorded a 24% increase in turnover to £108M for the financial year ending 31 October 2011, up from £87M in 2010. Operating profit also rose to £420,000. Despite the prolonged, weak economic climate we are currently operating in, Keltbray is experiencing significant growth, and has started to reap the benefits of an assertive diversification strategy and extended geographical reach,” said Group chief executive and owner Brendan Kerr. “From being a demolition and civil engineering focused business in the South East, Keltbray is emerging into a turnkey specialist business, which provides integrated services to meet the needs of diverse and complex contracts in the areas of demolition and civil engineering, rail and environmental materials management nationwide.” Keltbray’s demolition and civil engineering operations increased its turnover by 20% during 2011. This, the company claims, is a significant achievement in an increasingly competitive market, where margins are tight. Key to this development is the company’s joint venture, the Doosan Keltbray Consortium, which has been awarded several deplanting and asbestos removal contracts at Bradwell Power Station, as part of the five-year demolition framework contract set up by Magnox, which operates 10 nuclear sites throughout the country. Despite the uncertain economic outlook the company is optimistic about the year ahead. “We are in a great position to further bolster growth in the rail, nuclear and environmental sectors, which are amongst the few construction market segments that look strong in the short to medium term,” said finance director John Keehan. “We will also continue our strategy of building on our core strengths in demolition and civil engineering.”
Hilti’s positive intermediate results The Hilti Group achieved year-on-year sales growth of 7% over the first eight months of 2012 from CHF2,603M to CHF2,786M. The Group also made significant strides in profitability over the first eight months of the year. The Group’s operating result, at CHF180M, was 41% higher than the same period last year. Net income also improved more than three fold to CHF104M. “The good intermediate results confirm that the steps we have taken to improve efficiency and profitability were the right ones. We were also able to maintain the overall positive growth dynamic despite the fact that several important markets remain in a difficult position,” said Hilti chief executive officer Bo Risberg. “Nonetheless, we have not yet reached our goal. The economic environment will remain volatile and it’s important that we continue to concentrate on profitability in the future and that our investments be made selectively and in profitable growth segments.”

Words from the IDE President
“And now the end is near...”
It’s hard to believe that my two-year tenure as president of the Institute of Demolition Engineers is almost at an end. At our Annual General Meeting at the world-famous Lords cricket ground in London on 16 November, I will officially hand over the reins to my successor Steve Jack. It is with an enormous sense of pride that I will pass on the baton with the Institute stronger and more stable than I expected in these difficult times for the demolition industry. The hard line we took to ensure that all members earn their CPD points and sit the IDE exam will, by the time you read this, have resulted in the loss of 60 members. But what we may lose in numbers we have gained in national credibility and a much improved international reputation. Perhaps we could have taken a softer stance. But, as the saying goes, you sometimes have to prune a rose
good as the team around them, and I have been fortunate enough to have had the support of national secretary Valerie Stroud, vice president Steve Jack, events coordinator Duncan Rudall and a council of management that have been dynamic, enthusiastic and committed throughout. I owe each of them, and all members of the IDE, an enormous debt of gratitude for having permitted me to represent them as their president, and for the support they showed me throughout. My presidency has afforded me some incredible opportunities. I have represented the Institute at a huge number of events both at home and overseas, and I have met some fascinating people who will remain friends long after I hand the chains of office to Steve Jack. So while I will no longer be IDE president, I have no intention of fading into the background. The work of the IDE never ceases as it has come too far to stop now. I urge all IDE members to support both the institute and the incoming president, as well as you have supported me, and urge those demolition engineers who are not members to apply to join the IDE as soon as possible and add the letters MIDE behind your name to show the world that you are an expert in your chosen profession.

Baetsen buys a ZenRobotics Recycler In the Netherlands Baetsen Recycling has bought a robotic recycling system from ZenRobotics Recycler and is believed to be the highest technology currently available for waste management. The system, costing more than EUR1M, will be installed starting in February 2013 at Baetsen’s recycling plant in Son. The ZenRobotics Recycler system reclaims raw materials from construction and demolition waste, by using industrial robots controlled with artificial intelligence. Baetsen Recycling aims to be a front-runner in innovative recycling technology. “The increasing shortages in raw material supply, the under-utilized potential in waste materials and the complexities in manual waste sorting all demand a permanent, sustainable solution. Baetsen is taking the lead in recovering valuable fractions from waste,” says Baetsen Group chief executive officer Hans van Roosmalen.
CSDA new membership structure In the US the Concrete Sawing and Drilling Association has introduced two new membership categories that will allow the CSDA to cater to the needs of those who offer concrete polishing and ground penetrating radar imaging services. Many CSDA members have embraced technological advancements and added services to expand their sawing and drilling operations into full service companies. Some have even created separate divisions or businesses. Now, with these new member categories, CSDA is well placed to represent those who offer these specific services as a primary or additional revenue stream. “Good contractors are always looking at ways to grow their businesses and offer more to their customers,” says CSDA executive director. Patrick O’Brien. “Concrete polishing and GPR imaging have been two of the most popular services added over the past decade, so we began looking at ways to adapt and provide resources for current and prospective members who specialize in these areas.” The two categories have been added to the CSDA membership application form and website, and are available for contractors with immediate effect. However, membership is not the only thing that CSDA offers these contractors. As always, safety and training are a big part of what companies can gain through the association. The first ever CSDA Concrete Polishing class is scheduled for 6 to 7 February 2013 at the World of Concrete trade show and exhibition in Las Vegas. This two day classroom and hands on course is already attracting a lot of interest and is expected to be a great success. The association also has a specification entitled CSDA-PC-113 Polishing Concrete and a best practice named CSDA-BP-007 Ground Penetrating Radar for Concrete Scanning. Both documents are part of the CSDA Resource Guide and are available on
the association’s website. “These new membership categories are great news for us, as we can employ the help of more new and existing contractor and manufacturer members to produce useful resources to benefit polishers and GPR contractors,” says CSDA standards and specifications committee chairman Mike Orzechowski.

rapidly-expanding Latin American markets. At full capacity, the new JCB plant will have the capability to produce 10,000 machines a year. The new factory in Sorocaba City in São Paulo State replaces two smaller plants in Sorocaba, the first of which JCB opened in 2001 to produce backhoe loaders and the second in 2010 to produce tracked excavators. “JCB’s expansion in Brazil shows how British companies can capitalise on the opportunities for growth in Brazil, creating new opportunities in JCB factories in Derbyshire and Wales,” said Cameron. “This is a great example of Britain’s engineering prowess and reflects that the UK is a world leader in innovation and technology.” “South America represents a huge opportunity for growth for JCB and our investment in a new factory is critical to building on the success we already enjoy in this important market,” said JCB Chairman Sir Anthony Bamford. “There are £20bn worth of infrastructure improvements scheduled in Brazil and JCB’s new factory will enable us to capitalise on those projects, including the 2014 World Cup and 2016 Olympic Games. JCB’s decision to invest is a big vote of confidence in the Brazilian economy and was driven by the excellent long-term growth opportunities both here and in Latin America. Our investment will also have a positive impact on the UK economy because at full capacity, the Brazilian plant will import £100M of components annually from the UK including engines and transmissions.”
Unique Demolition Award Sculpture
The winners of the newly established Swedish Demolition Awards (see pages 48-49) each received a crystal glass sculpture made by glass blower Mikael Johansson on behalf of Gränna Glass. Mikael Johansson calls himself Micke Johans and works in his own company Micke Johans Art Glass Foundry in the village of Örsjö, a short distance from the famous crystal glass foundry Orrefors in the heart of what is called the Kingdom of Crystal in the Swedish province of Småland. Mikael Johansson differs somewhat from other glassblowers. He has taken the step from being an employed glassblower to opening hiss own foundry. But mostly, he creates his own utility and art glass. In Micke Johans Art Glass Foundry visitors get to see a number of beautiful vases and masks, some made in Grail technology and other types of art glass.
Mikael Johansson became a glass blowing master when he was only 24 years old. He was born in 1972 and grew up in the small community of Flerohopp, next to Orrefors. For eight years until 2004 he worked as a glassblower at Orrefors Glassworks. After Orrefors he worked at Pukeberg Glassworks, where he created his own utility and art glass. But in 2011 he took the plunge and opened his own foundry in Örsjö. “I’ve always liked to work with glass. But in 2000 I had the opportunity to take my interest to a new dimension when I, thanks to the well-known Swedish artist Ulrika Hydman Vallien, had the opportunity to go to Pilchuck Glass School and broaden my horizons in the fantastic world of glass,” says Johans. Each of he Swedish Demolition Award statuettes is a unique art of Mikael Johans, while the original design was actually made by PDi’s editor-in-chief Jan Hermansson.
New managing director for Keltbray In the UK the Keltbray Group has appointed Bob Johnstone as managing director of the company’s Industrial and Explosives Division. Johnstone has 25 years of experience as a consultant to the industry and Keltbray, providing structural design services and managing large-scale construction and demolition projects on highly regulated sites within the industrial, petrochemical and nuclear sectors. “We’re delighted Bob is joining us, as his understanding of how a building was originally designed, and how the structure may have been altered and deteriorated over the years, is essential when considering demolition options,” says Keltbray Group managing director John Price. “This is especially the case when using controlled explosives, where ensuring workforce safety during the building preparatory works before blowdown, and achieving the designed mode of collapse during blowdown, are both crucially important to the success of the project.”
Trevi Benne celebrating its 20th anniversary In July the Italian manufacturer of demolition and recycling attachments Trevi Benne celebrated its 20th anniversary at their factory in Noventa Vicentina. The company was founded by Luca and Lucia Vaccaro and has seen considerable development during its 20-year history. One of the company’s strengths is its ability to listen
to its clients and find out exactly what kind of attachments they need. Trevi Benne is never afraid to develop what their clients need and over the years has launched many heavy-duty demolition and recycling attachments.
The celebration party in July attracted about 1,200 guests from all over the world. PDi will publish a report on the company and the festivities in the next issue.

SPE’s MP6000 surface grinding attachment
In the UK surface preparation equipment manufacturer SPE International has been commissioned to produce a multiple triple head surface grinding attachment to fit a customer’s MP6000 sit and ride preparation unit. The contract required the surface grinding of a concrete and asphalt product to expose both stone and sea shells that had been blended into the material. The MP6000 was originally purchased with shot blasting and planing attachments. However, SPE’s client was awarded a large outdoor grinding contract and proposed to use the MP6000 to carry out this work. SPE designed and manufactured a solution based on the
company’s DFG700 planetary grinding machine. The planetary grinding heads were mounted into a custom built support frame that allowed the heads to pivot in all directions. The whole attachment raised up and down hydraulically to allow the fitting of various grades of diamond grinding tools. Each head could be started and stopped and the grinding speed adjusted independently in a seated position by the operator. The MPG700 triple was used to grind through various stages completing 10,000m2 of a sea front promenade to the specified finish in just one week.

UK Keltbray Scaling demolishes new heights cement plant Specialist decommissioning experts at Keltbray has started demolishing part of the Barrington cement plant in Cambridgeshire, following the decision by plant owner CEMEX, not to restart production. Barrington is one of only around a dozen remaining cement plants in the UK. Originally ‘mothballed’ in November 2008, CEMEX concluded there was no economic case to re-start production, and commissioned Keltbray to undertake the first stage of a phased demolition of the plant. The part-demolition is due to be completed in October and expected to yield around 200t of metal, including steel and copper, for processing and recycling. Keltbray was awarded the Barrington contract partially do to its demolition of CEMEX’s Southam cement plant in Warwickshire earlier this year, and in particular Keltbray’s health and safety record on this job. “Keltbray spent nearly 18,000 man hours on site, and we were delighted that the job was completed without a single health or safety related incident,” says CEMEX cement division senior projects manager Colin Mousley. As with the Southam contract, Keltbray has developed a model for sharing the commercial recovery benefits with CEMEX. Keltbray secured the 16-week contract at Barrington to carry out asbestos removal and disposal, the removal of hazardous wastes and part demolition of three key areas of the plant, including part of the cement kiln and building, the precipitators, coal handling plant and tippler buildings. The four-month contract is now well underway and progressing well. “I was fortunate enough to bring most of the people from the Southam job to work with me here in Barrington,” says Keltbray
project manager Kenny Fisher. “This means we’re able to build on the experience we gained in Warwickshire, and extend the good working relationship we had established with CEMEX.”

In the UK a Yorkshire drilling firm has scaled new heights to complete a contract for one of the world’s biggest companies. D-Drill, a diamond drilling and sawing specialist with a base in Sheffield, was called in by Tata Steel, in Scunthorpe, to drill a series of 151mm diameter holes, 300mm deep using specialist equipment. There is nothing out of the ordinary about those particular holes, except the fact that they had to be drilled at heights of up to 100m. They were required at several stages up a chimneystack to allow fabricated steel bands to be fixed to it with steel locating pins. This required specialist training for the two D-Drill operatives doing the work in order to get them used to heights and skilled in using safety harnesses. They were lifted in a man-riding basket suspended from a crane and drilled the holes over the course of several visits. “The work was not out of the ordinary, apart from the fact it was being done at 100m above the ground,” said D-Drill Sheffield based manager Mick Brown. “We were asked to get involved with this work at the planning stage and we were delighted that our knowledge, skill and expertise were utilised by one of the world’s best known companies. Of course, it wasn’t just down to skill. Our guys had to have the stomach for heights too and they said from the start that it would not be a problem. “As a company, we do not leave anything to chance so they undertook specialist training to work at height and there were also rescue teams on hand with abseiling equipment should anything go wrong when they were carrying out the drilling. “The job also had to be postponed on a couple of occasions due to high winds because safety was of prime importance. Such was the success of this stage of the work, Tata have now called us back in to discuss further projects.”
ity of the design and high quality of the components. But whatever their strategy and priorities, it is the tool’s performance that matters, and this is what every attachment manufacturer strives to deliver. Despite the sluggish market, or maybe, thanks to it, the players home in on making high-performance tools that are able to complete a job as quickly and efficiently as possible, thus reducing high labour costs. Demolition attachments differ very much in design and purpose, therefore this product review is structured according to the attachment type and application.
Processing of scrap metal is a business that is becoming increasingly important for attachment manufacturers. Immense and lucrative, it offers plenty of opportunity for suppliers to prop up their balance sheets. North America is arguably the most advanced market for scrap processing at the moment, where the acknowledged trendsetters in the field of Stanley LaBounty, Allied-Gator and Genesis are based.
As 2012 draws into the final quarter, it is time to make some preliminary observations of its results. For the demolition industry, the year turned out to be a challenging one, with most markets either falling or, at best, remaining flat. This is also true of the demolition attachment segment. Only a precious few markets like Germany, US, Scandinavia and, to a certain extent, Russia are reported to be growing, while the rest of the world stagnates. Nonetheless, manufacturers keep introducing new products in an attempt to revitalise the languishing market with the offer of high-performance tools. Andrei Bushmarin reports. Demolition attachments are a fiercely competitive sector featuring a whole plethora of players from Europe, Asia and North America. To get an edge over competition, they employ different tactics. Some bet on low price and affordability of their tools and others on ingenu-
Stanley LaBounty LaBounty, a company within Stanley Black & Decker Group, has been manufacturing attachments since 1973. Its latest scrap shear, the MSD 4000, is the ninth in the Saber Series, and incorporates all standard features, including rotation options, high-performance reversed cylinders, speed valves and bolt-on replaceable wear parts. Weighing in at a mighty 8.5t, the MSD 4000 is one of the most powerful rotating shears in its class. It can cut a wide range of construction materials, including I and H-beams, channels, steel plate, pipe, round stock, wire, rebar, and concrete. Its cycle time varies from 9s to 12s depending on the type of base machine. Additional features include narrow stick body for better visibility and updated swivel with grease transfer capability.
Demarec Breathing down the Americans’ necks are their European competitors. The Netherlands based company Demarec, one of Europe’s majors in the demolition attachment industry, is closing in on the leaders with its DRS series line of 360° rotatable scrap shears. It is available in six size variations for excavators ranging from 14t to 100t operating weight. Apart from scrap processing applications, they can be used for demolition and tyre recycling jobs. The DRS tools, which have three different mounting options, boast blades with offset apex for increased cutting force, the exchangeable and re-weldable piercing tip, the shear arm guiding system and the blade blocking

system in both jaws. All blades are three or seven times indexable. The scrap shear market has excellent long-term potential, believes Demarec sales and marketing director Marcel Vening.
Arden Equipment Arden Equipment, another well-known name in the attachment business, used Intermat 2012 to showcase the prototype of its new scrap shear AS-030-R61 that would replace the existing AS-027R. The new model is 10% heavier than its predecessor, with improved kinematics and redesigned jaw, which has resulted in a 15% increase in the jaw’s closing force. According to Arden’s marketing manager Eric Daubail, the shears have put up a very convincing performance during testing. Also new from Arden are the prototypes of multiprocessor CU-31, complete with a jaw quick-change mechanism, and of pulveriser BBH030, which will be available in rotatable and non-rotatable versions. All three models will be launched early next year. Sales wise the global attachment market was alive rather than dead, especially in the first half of the year, but the ownership costs remain an ongoing concern for end users. Arden’s solution to this problem is to develop tools with an optimum power to weight ratio, standardised components and wear resistant working parts.
Poqutec Korean company Poqutec may be less known than its American and European counterparts, but that does not mean that it has less to offer in terms of product range. Poqutec produces a full line of attachments for demolition and recycling, but the main thrust is on tools for heavy-duty secondary demolition. For scrap processing, Poqutec offers a series of the PHMS 0510 R-1 mini-shears, designed with small hydraulic machines in mind. The shears are suitable for scrap and demolition applications, such as cutting and lifting of heavy wire, rebar, pipes, Ibeams and concrete. Lightweight and compact, they are intended for carrier machines of up to 10t. All models come equipped with a 360° hydraulic rotator.
Darda Germany-based Darda, Demarec’s sister company from the Kinshofer Group, develops steel-handling tools of its own. Steel cutter CC700S is Darda’s most recent innovation. Ideally suited for mini-excavators and demolition
robots, it is compact and extremely powerful. Boasting a cutting force of 188t, the CC700S can remove almost any kind of steel structures including I, U, and H beams and stainless steel pipes. The cutter operates within a pressure range of 17.5 to 27MPa and has a cutting depth of about 360 mm.
CRUSHERS, PULVERISERS AND MULTIPROCESSORS
Concrete crushers and their many variations, like pulverisers and multiprocessors, are probably the most versatile demolition tool of all, equally handy for primary and secondary demolition tasks. In the former, crushers are used to bite off structural elements of a building, and in the latter to pulverise the concrete and separate it from metal for disposal. Although countries with developed economies remain the biggest consumers of crushers and multiprocessors, developing nations are beginning to catch up with them.
Cat Work Tools With wide jaws with pick-up tips, reversible cutting edges and short cycle times, the P200 series from Cat Work Tools is a solution for secondary demolition and recycling. The ripper tooth splits concrete, while the large number of crushing teeth create the pulverizing effect. The cylinder of the P200 is equipped with a speed valve as standard, which enables the crusher to cut and pulverize efficiently. Thanks to a mounting bracket, the attachment can be quickly mounted and removed from the carrier machine. Since maintenance is a major factor in ownership costs, the crusher’s teeth and blades are replaceable and its hydraulics easily accessible through the bolted hatches.
Rotar The Dutch manufacturer has upgraded the design of the upper jaw on its proven RDP pulveriser. The new design allows for better penetration into concrete thanks to the two high teeth positioned in the middle of the jaw. The side teeth help remove the concrete around the rebar. By turning the tooth adapter, users are able to control the wear of the teeth, thus choosing the optimum work mode and increasing the life span of the tool. The jaws in the new design are available for the RDP 20/25 and 32 types.
Allied-Gator The MT-series of hydraulic attachments from the US based Allied-Gator is versatility personified. The patented Allied-Gator MT Quick-Change Shear, Cracker/Crusher
and Densifier jaw sets can be switched in the field in as little as 15min, allowing users to juggle multiple tasks onsite, including structural steel processing, concrete reduction, cast processing, rail breaking and material handling. This solution enables a customer’s single machine to perform each application to maximum effectiveness. Other MT features include unrestricted 360° rotation, patented Allied-Gator Speed-Circuit technology, and patented Allied-Gator UCS technology.
Peter Wassenaar, managing director of the Netherlands based attachment specialist Hydraram, with almost 25 years in the attachment business, believes that the arrival of demolition grapples was one of the major milestones in the industry’s evolution. It allowed demolition contractors to considerably enhance their performance onsite and saved them a lot of money in labour costs. Since its introduction, design of the tool has been changing and evolving.
The MK series of multiprocessors with hydraulically interchangeable jaws from the Italian manufacturer Trevi Benne is a big hit with contractors, the company’s Dutch distributor Hydraram claims. Due to a special jaw construction, which allows it to pick up the material and cut the concrete and rebar in a single stroke, the MK pulverisers are an ‘all-in-one’ solution for demolition and recycling tasks. The user can select from the five jaw types of combi, punch, scrap, pulveriser, plate and tank, and if necessary, change in a few minutes. The pulverisers boast a rotary motor protected by additional shock valves, a double-bearing swivel head for extremely tough applications, built-in speed valve and replaceable teeth and blades. The MK attachments are available in five modifications, ranging in weight from 1t to 4.4t and are suitable for 9t to 65t excavators.
Another Dutch supplier Euroram-Rockmaster has complemented its Globram range of demolition grabs with a new model RM705D. The principle difference with the RM705D is that it is fitted with perforated tines. Classic demolition grabs have ribbed tines that lend robustness to the attachment. But grabs with perforated tines are the best option for material-handling applications. According to Rudi Spinner, Euroram’s managing director, the idea behind the innovation was not to replace the existing ribbed tine range, but rather to supplement it with a perforated model. Given that they are easily interchangeable, having both on a job site will add to the user’s versatility.
Promove Italian company Promove keeps abreast with the Dutch in the pulveriser market. Its new CF 350 XL model is intended for heavyduty crushing and recycling. Weighing 3.4t, the CF350 XL is complete with robust jaws, a big cylinder with a speed valve, replaceable teeth and four time indexable blades. The CF tools are manufactured from Hardox 400 steel, with their cylinders protected in a special way. The CF 350 XL is designed to operate with 30t to 50t excavators.
DEMOLITION AND SORTING GRAPPLES
Over the years, demolition and sorting grapples or grabs remain an indispensable tool for primary applications.
NPK In September 2012, the Japanese company NPK announced the launch of two midrange models of demolition and sorting grabs. The new arrivals, DG 4 and DG 6 are suitable for 2.5t to 6t excavators. Both models are complete with a hydraulic rotating unit, reversible and interchangeable cutting jaws and a frame made of Hardox steel.
Sandvik Sandvik used the recent Hillhead construction, mining and quarrying equipment show in the UK to launch a new eight-model range of demolition and sorting grapples under the recently unearthed Rammer brand. The range, which is compatible with a wide spectrum of carrier machines, can be divided into two categories. The first five models are for excavators of up to 40t covering regular demolition and recycling applications, while the remaining three are heavy-duty attachments. The standard models made of HB 500 steel feature a 360° rotating unit and a mounting system identical to that employed in other Rammer products. The larger 1877, 3077 and 4577 are equipped with a set of sturdy inner jaws having a crushing force of 500kN to 800kN. In case no crushing or pulverizing is required, the jaws can be covered with protector pads.
VTN Europe VTN Europe’s new line of material handling grapples is called the MD series. This multi-model line covers the excavator range of 2t to 60t and features a 360° rotation Issue 4 • September - October 2012 •
option. The larger models of the range, the MD 210 to MD 290, are complete with two cylinders with an opening brake. The updated design elements include a low-slung profile, and a reduced number of larger pins. The hydraulic motor positioned on top of the grapples is equipped with a speed valve that permits control of rotation speed. The new tools show a greater gripping force thanks to a new kinematic system, two cylinders and one-lever synchronism. All models come with the opening mechanical stops. Flow and pressure valve is optionally available.
At Intermat, Montabert, best known for its hydraulic breakers, debuted a four-model range of rotating crushing and screening equipment. It is compatible with 10t to 35t carriers and can handle various inert materials, such as concrete, asphalt and natural stone. The machines, designed for heavy-duty applications, are able to reduce construction debris down to particle size of 20mm to 120mm. All models come equipped with wide aperture buckets, guaranteeing efficient performance. For processing of reinforced concrete, an electromagnet is optionally available.
CRUSHING AND SCREENING BUCKETS
Crusher buckets are the ultimate recycling attachment that allows processing of demolition debris onsite. Once a niche product that only a chosen few developed, crusher buckets are now a staple of every attachment manufacturer’s arsenal. The key advantage of crusher buckets is that they operate using the host excavator’s hydraulic power, which eliminates the need for a dedicated recycling unit. This year saw a few launches in this product group, with most of the suppliers using Intermat as a show room for them.
Atlas Copco Atlas Copco has also strengthened its positions in this sector by launching a four-model range of crusher buckets, suitable for any carrier machine weighing upwards of 12t. The new buckets that weigh from 1.5t to 4.9t boast a winning combination of high productivity and low maintenance. Standard greasing interval is 30 hours, with only two greasing points required. The bucket jaws are built to endure high levels of stress. Invertible, rotatable and exchangeable, they are designed for efficient and lasting performance.
MB Crusher Meccanica Breganzese, one of the pioneers of the crushing bucket technology, displayed two models at Intermat, the BF 150, which is arguably the world’s biggest crushing bucket weighing 10t, and the diminutive MB-L designed for mini carriers. The gargantuan BF 150 for excavators weighing upwards from 70t is an ideal solution for large quarry jobs. MB-L, the manufacturer’s smallest attachment so far, is a very compact yet versatile and productive tool, which is suitable for a wide range of applications.
The new D series of crushing and screening buckets from the Finnish recycling specialist Allu boasts a number of significant advantages over their forerunners. First off, they are equipped with fender plates to protect axle seals and bearings, which results in longer maintenance intervals. Another patented feature is the horizontal drum assembly with bearings at the backside of the bucket. Also, any bolts or nuts that might interfere with the material flow inside or outside of the frame have been removed. This makes the bucket wear resistant and maintenance friendly. Another innovation concerns the recycling of fine power material. In areas with high humidity levels powder material tends to form lumps. That makes its processing less efficient, with the end product not being size homogeneous. To overcome this, Allu has equipped its crushers with hydraulically operated hatches that keep the fine material inside the bucket during transportation to the recycling site. Once at the site, the hatches are

opened to release the lumps that get crushed and screened to the same size as the rest of the material.
Dehaco and Zato Dehaco Group, a Dutch suppler of demolition and dust control solutions, is marketing a device developed by Italian manufacturer Zato. The new equipment, called the Blue Devil, is a cross between a crusher bucket and a scrap shear. It consists of the container housing a hydraulic unit, motor and electrical panel and a kind of giant crusher bucket with rotating knives inside. But unlike a regular crusher bucket, the Blue Devil is first and foremost used to process steel scrap. Rebar, metal plates or car parts are loaded into the hopper and get cut and crushed by the rotating knives. The resulting product is downsized feed material for steel mills.

The new RS 4500 from Rusch The new Rusch demolition excavator RS 4500 has been designed for demolition. Although a standard excavator has been used, without the boom, many parts have been replaced and others extremely modified. The reason that a standard excavator is chosen is the worldwide service of the heart of the machine, the engine and the pumps. Cost wise it is beneficial for customers to buy the standard spare parts from the local dealer rather than to buy the components through Rusch. Only the specific parts like boom and safety system needs to be bought from Rusch. Some modifications to the machine include
lengthening of the tracks, the machine can operate at full capacity over 360° continuously. The hydraulic tank has been enlarged. Counterweight has been added with a total weight of 24t. The main frame has been strengthened. There is a new sub frame with new longer stroke boom cylinders and boom carrier. This system is unique and together with the hydraulic pin connection has been patented. The system allows the machine to take different booms, such as telescopic high reach, long reach, deep reach, dredging, lifting, drilling, piling and excavation and ripping. There is a new type of boom and the hydraulic system has been modified with a new control system that has an interface with the safety system. The full capacity of the base machine allows for fitting special tools, such as a

This system warns the driver of approaching dangers and stops the endangering movement of the machine. The RS 4500 can operate with a 5t tool and still have capacity take another 1t in the jaws. Heavier tools can also be handled depending on the machine configuration. An 80t base machine can cope with a 10t tool. The RS 4500 has been designed to fit in the European transport envelope in size and weight. The RS 4500 has its own lifting device in the Retrofit boom and can erect itself. Another unique feature is that Rusch allows the use of a hammer on all boom members. A 3t hammer can be fitted to the fourth boom section to a height of 40m
Mantovanibenne Aids Dockside Demolition
Mantovanibenne’s UK importer International Marketers (London) has supplied two MBI demolition attachments to Heavy Decom International for a contract in Portsmouth Harbour, where HDI is demolishing and removing redundant cranes. The task required demolition works above and below water and all the equipment was mounted on a large barge. HDI brought in their 200tHitachi EX1200 excavator, which had been rebuilt by Kocurek of Ipswich to HDI’s specification. The rebuild enabled the Hitachi could carry an hydraulic attachment weighing up to 8t, working at a maximum height of 40m with a four-piece boom. Two MBI attachments were provided by INMALO for the contract. A CR100 hydraulic crusher for demolishing the crane foundations above and below the water and an SH900 hydraulic steel-cutting shear for dismantling and shearing the steel structures of the old cranes into manageable sections for recycling. The CR100 is a 11t twin ram crusher, while the SH900 is a 10t shear, believed to be the most powerful in its class. “Both attachments have proved their worth on this contract and the CR100 in particular is an amazing piece of kit with its 2m jaw opening and awesome crushing power,” said HDI representative Hardy Worsey.

Sennebogen’s 818 R Electro at Polcopper
Concrete Cutter welcomes local MP
Scrap car bodies, thousands of tin cans or parts from the metal industry are delivered every day to the largest scrap yard run by Polcopper in Smigiel near Poznan, Poland. Two Sennebogen 818 Electro with crawler chassis have recently begun work at the site supplying the packaging press. Polcopper has grown into a world-renowned family-run recycling company with an unparalleled development story. Founded in 1990, the company has developed from a small scrap yard to market leader in Poland in the field of scrap management active all over the world. General manager Piotr Rusiecki has been running the operation since 2000 and handles around 500,000t of scrap each year with 300 employees. Two new Sennebogen material handling machines are now operating at the company headquarters in Smigiel near Poznan, where they continuously supply two packaging presses. Low running costs, minimal background noise and high reliability are key advantages compared with conventional drive versions. Equipped with an 11m long boom and the elevating Multicab comfort cab, the Sennebogen 818 is ideally suited to the work on the packaging press. The machine reaches over 100 cycles/hour when handling metals of all types and shapes. With the stable wide track crawler chassis, the 818 always stands firm and can also be turned around and moved easily as required. The hydraulically
In the UK the Member of Parliament for Rugby Mark Pawsey was able to drill down to some of the issues facing the British construction industry when he visited D-Drill in his constituency. Pawsey was shown the work of the company and was taught the basics of drilling by apprentice Mark Bartlam, while D-Drill managing director Julie White outlined some of the challenges facing the company. “It is really important that I have strong links with companies in my constituency,” said Pawsey. “Not only can I offer support with any issues they face, but also it gives me a real understanding of the business landscape and how Government can help with national policy. I can then feed that back to the relevant people or bodies at Westminster. “I had been aware of D-Drill through the awards it has won, but it was really interesting to see its work close at hand. I was delighted to see how well the company is doing in the face of a difficult climate, particularly in the construction sector. Julie White is obviously a very hands on managing director, driving her business forward and I wish her every success. I will look forward to welcoming her to Westminster when she visits in the near future. D-Drill as a company puts a great deal of emphasis on training and bringing young people into the industry, which is fantastic. It was clear to see how much Mark enjoys his work and values the opportunity the company has given him.” D-Drill takes on around 12 to 15 apprentices every year, but has trouble recruiting suitable candidates because of its specialised nature and the fact it is spread across the UK. “Unfortunately we do not fit into criteria set down by the National Apprenticeship Service, which means we get no help in recruiting our apprentices,” said Julie White. “Also we are not able to have access to young people who want to go into construction, but have not been kept on by national operators at the end of their apprenticeships. Both those factors do make it difficult for us and mean that we have to go through a massive amount of time; a process, which we believe, could be made a great deal easier. Sometimes, when you are an independent company, it is easy to feel you are banging your head against a brick wall. Mark Pawsey used to run his own firm and it was clear from the meeting that he understands the pressure companies like ours are under and has promised to look into the issues.”
Polcopper uses two new Sennebogen 818 Electros with crawler chassis to supply the packaging press at the scrap yards near Poznan. elevating cab, combined with 300mm pylon elevation, provides an unrestricted view into the press from above. Reliability and low costs are the most important criteria for Rusiecki. In addition to the low running costs, the 818 has also impressed with its environmentally friendly properties, a factor which Rusiecki is certain will increase in importance in the future in light of rising energy prices. The machines are in operation 24 hours/ day with no refuelling break thanks to the electric drive. Material is gathered constantly from the surrounding smaller scrap yards, sorted and
then loaded onto vehicles. The easy operation and high power reserves make the machine a reliable partner in everyday use. The drivers and managers are extremely satisfied with the service provided by the Polish sales and service partner Bax Baumaschinen. “We decided together that the Sennebogen 818 was the optimum machine for our needs. The technicians are on site quickly when needed and support our drivers and mechanics with all maintenance work. This is a key aspect, as we can’t afford downtime,” said Rusiecki.
Doosan excavator on house demolition Klaus Anthes, owner of a company with the same name, specialising in demolition, transport and earthworks, has carried out a demolition contract on a family house in Eppstein in Germany, using a Doosan DX235LCR excavator. The project provided a demonstration of what can be achieved with this 24t reduced radius model in the tightest of spaces. The demolition work presented a number of challenges as the old house was located on a hillside in Eppstein and right next to a narrow road. To ensure that the flow of traffic was not disrupted during the demolition, the excavator could only be used within the confines of the property. Also the replacement building had to be built on the existing natural stone cellar, which
had to be protected from damage during the demolition work. To meet these requirements Klaus Anthes decided to hire a Doosan DX235LCR excavator with a sorting grapple from Bobcat Bensheim. The 24t model has a short radius design with only 185mm of overhang and a swing diameter of 3.99m, allowing the contractor to work in very confined spaces. Anthes operated the Doosan DX235LCR machine. ”The reach and stability of the excavator were crucial on this project,” said Anthes. “All of the demolition work had to be carried out from the front yard. That meant we needed a machine that could reach up to 8m into the property while still having excellent stability to stand securely
on the slope at the site. The Doosan excavator also has the advantage that its arm can be fully retracted and that made it easy for us to turn in this confined space.” The demolition required the removal of about 200m3 of rubble, wood, metal and other debris and the waste material was sorted before disposal from the site. ”Thanks to the precise and sensitive controls on the excavator, we were able to save valuable time. In fact, we used the sorting grapple to sort most of the waste material during the demolition work itself,” said Anthes. The contractor needed only 15 hours with the machine to complete the demolition and the construction of the new building began immediately thereafter on the remaining basement. Klaus Anthes, who founded his company in 1995 and now has 30 employees. He has been a customer of Bobcat Bensheim since 2008, and has purchased 14t, 25t and 30t Doosan crawler excavators, as well as two Bobcat compact excavators. In 2007, Bobcat Bensheim and its locations throughout Germany became a company branch for Doosan Infracore Construction Equipment. Since then, the company has been renting and selling the heavy machine product line from Doosan alongside the Bobcat line of compact machines.

Aquajet’s new power packs for hydrodemolition A new range of containerised, high pressure power packs from Swedish hydrodemolition specialist manufacturer Aquajet Systems designed specifically for hydrodemolition applications, feature four models including two Ecosilence versions meeting an average 57.5dB noise level B o t h v e rsions of the top of the range Power Pack 700 have a working pressure of up to 1000bar with a power input of 473kW. The Power Pack 400 Ecosilence has a maximum working pressure of 850bar and a power input of 276kW. The standard high pressure Power Pack 400 unit offers an increased maximum working pressure of 1150bar. The Ecosilence versions offer a substantial reduction in fuel consumption. Its design ensures that just 70litres/hr is used when producing a water output of 185litres/min at 1000bar. Maximum output is 261litres/
min at 1000bar. The power packs’ diesel engines and high-pressure pumps for all versions are assembled complete on a steel frame with a built-in 925litre diesel tank in the Power Pack 700 models and an 820litre tank in the Power Pack 400. A remote control system with a pressure ‘on/off’ switch and emergency ‘stop’ button is included. When the remote control is switched to the ‘off’ position, the system will de-pressurise the pump and high pressure hose and reduce the engine speed. Hard wired remote control is standard with radio control optionally available. The new Power Pack models also incorporate a built-in work bench complete with a vice and storage room for spare parts. Movable heavy hooks are also fitted for storing high pressure hoses and cables.
Hydrodemolition saves time in Australian mine One of Australia’s leading hydrodemolition specialist contractors, HiTech Industrial Services, has removed a defective section of blade wall from a mine in Mackay, Queensland using two Aquajet robot cutters, reducing what would have been a six-month job to just four weeks. The problem had arisen when an incorrect batch of concrete had been poured for a 9.3m high by 9.3m long section of the 1m thick blade wall. Removal of the section was necessary and wire sawing was not possible. “Using an Aqua Cutter 710V Evolution and an Aqua Cutter HVD6000, meant that our total time on-site was just four weeks, compared with an estimated six months or more required for wire sawing,” says HiTech operations manager Damien Turner. “There was a 32,000V rail line behind the site that is used to transport coal. The line is just 2m behind the wall and we proposed placing an 8mm thick steel plate behind this wall, which was supported by formwork and props, to prevent flying debris hitting the trains. It also stopped the water jet from hitting the power cables. “Apart from the speed and convenience of the removal rate using the hydrodemoli-
tion technique, the idea of the safety shield helped us to win the contract. It was important that the trains continued working and there were no delays as a full trainload of coal is valued at A$3M.” The concrete being removed had a strength of 40MPa, with 32mm diameter reinforcing bars generally spaced at 150mm and 200mm, although in some places the spacing was only 50 mm. Using hydrodemolition ensured that the rebar was not damaged whilst removing the defective concrete. HiTech was on site for four weeks and working or on standby round the clock, and removed the 86m3 of defective concrete in 172 blasting hours. “There was a good deal of reorganising and other work going on at the site, and so much of our time was spent on active standby,” said Turner. “The actual work presented no unexpected problems for the Aquajet robots. The 710V Evolution was equipped with an 11m mast to enable it to reach to the top of the wall, while the HVD6000 was fitted with a standard 5m mast.”

The Lundin family, specialists in dust extraction equipment from Gällö, Sweden, have returned to the air treatment business with a new company Sila.
Both models are equipped with auxiliary power outlets.
In the forests of the Swedish province of Jämtland inventor Erik Lundin developed and manufactured air cleaners, dust extractors and cyclones with product names such as Aermin and Ermator. Erik passed away several years ago and shortly afterwards the company was sold to Pullman Scandinavia, now Pullman Ermator. But the Lundin family has now resurrected the development and manufacture of dust handling equipment under the new independent Sila brand.
Back to the roots
Erik Lundin’s son Mats has grown up with dust handling equipment his whole life and worked for many years side by side with his father learning the craft and how to do business. Other family members also worked in the previous company, including Erik’s grandson Andreas Lundin and relative Ralf Nilsson. The business was sold shortly after Erik died and Mats, a devoted musician, decided to live his dream and build a recording studio. In the meantime Andreas studied communication and advertising in Stockholm and started his own advertis-Easy transport. ing firm, while Ralf worked as a designer at another company in the region. “But somehow, we kept coming back to our roots, which were well planted in the soil of dust handling devices,” says Mats Lundin. “When we met we always discussed new possible products and ideas for air filtering and vacuuming hazardous
dust. For various reasons, possibilities suddenly opened up which made it easier for us to take the final decision to start producing dust-handling equipment again. We also had requests from many of the old company’s former customers if we would be starting again, so about a year ago we decided to set up our new company Sila.”
Andreas Lundin says that they have decided to focus mainly air cleaners and different accessories to improve the indoor working environment. “But now - as before - back when Erik had the company time, it is important not to think like all other manufacturers in this field. You have to think outside the box, so to speak - even if it’s a terrible cliché - and come up with something completely new,” says Andreas. “The focus of our business is on the user and his family. Our products should be - and are - effective, safe and easy to work with.” Sila has only been operating for a few months, although product development has been in progress for quite a time. But it is only this year Sila seriously started marketing the company and its products. The first products are the two air cleaners, Sila1000A and Sila 2000A. They were officially launched at the Swedish demolition show DEMCON in September. “Detailed information about our new products can be found on our website, but in general they have a very smooth design, easy to set up, carry and transport. The compact design and low weight does not affect the powerful capacity of the two air cleaners,” says Andreas. “The most important aspect of our air cleaners is safety. Therefore our products have no eccentric locker or snap on locker,” says Ralf. “This is one detail that significantly increases the safety for users and offers a better performance of the product.

r went out It actually doesn’t matter if a product has a HEPA H13 filter if the product itself has weaknesses. Therefore our filters are fixed with proper screws. We therefore minimise the risk of quartz and asbestos particles to contaminate the clean side. Eccentric lockers have a tendency to slide up during transport or break if they get hit.”
The smallest air cleaner, Sila 1000A, has a flow of 1,000m3/h and measures just 300 x 514 x 495mm. It has two speeds, and is provided with a coarse filter and a HEPA H13. Power is 185W and it weighs 15kg and is stackable. Sila 1000A is ideal for use in small spaces. The bigger Sila 2000A has the capacity to clean larger areas, for example when jack hammering or floor grinding. It has a flow of 2,000m3/h and a power of 455W. Equipped with coarse filter and HEPA H13 it purifies 99.95% of the most dangerous dust particles. The weight is 25kg and measures 350 x 720 x 697 mm. Both models are fitted with auxiliary power output of up to 1500W. In addition, they are fitted with a filter guard that alerts when the filter needs to be replaced. Other features of Sila 2000A are rear wheels and a metal bow with adjustable handle. The bow makes the transportation of the air cleaner smoother. Wheels and handles make the model easy to move around. And both can be fitted with an exhaust hose as an option. Another accessory is the sanitation frame. This is a system that helps the customer to encapsulate a room and create a vacuum, thus efficiently expelling all kinds of dust and particles. The system was developed back in Erik’s time. But Sila has refined it and made the set-up faster and safer. If for instance a bathroom under renovation is sealed with a plastic in the door opening the air cleaner is placed on the outside and the sanitation frame on the other side. The frame is fitted with magnets and attaches easily to the air cleaner. The operator just has to cut out the plastic inside the frame, which is available for both air cleaner models.
Sila is now in full production and a number of products have already reached customers. “We have already received some amazing reviews about our products and understandably we are very pleased with that. We feel very encouraged to get as many products as possible out on to the market since these products speak for themselves and will convince our customers more than anything we can say or write,” says Mats Lundin. Initially, the emphasis is on the Swedish and Norwegian markets. In Norway, the company is selling their products through their dealer Norman Olsen, and who knows the Lundin family tradition. “First, we want to be strong domestically and Scandinavia is our platform, but we expect to begin to explore the possibilities for export to Germany as early as next year,” says Andreas. “Nothing will stop us. We want to get our products out in several markets in Europe. Of course the US is an attractive market for us in the long run and also other parts of the world. But right now we are taking one step at a time. The customer Issue 4 • September groups we are targeting Smooth transport.

are mainly concrete cutters, renovation contractors, companies working with concrete floor grinding and polishing, demolition contractors and of course the rental industry.” The current focus is on air cleaners and a range of accessories. But Sila has a long tradition of knowledge of dust extractors, cyclones and other products. The three entrepreneurs agree on that user-friendliness and customer safety are paramount. They also stress that all products that come from Sila are designed and manufactured in Sweden and that it will remain that way. “All the components are produced locally. We want to be close to our partners, because that makes our footwork so much more effective. Local production and hands-on management benefit the quality and in its turn: our customers.” says Mats Lundin.

Cold Pressing of diamond beads with the new BCP 100 The diamond wire technology is a success story. The growth of this tool was impressive, but to a certain extent not extraordinary. The main fields of application were quarrying, slabbing, profiling and the construction applications. However, the game changed with the growing success of multi wire machines, which are now creating a very fast growing demand of very thin wires. By Dr. Fritsch president Gerhard Weber
The task was to design a cold press that is fast, reliable
and guarantees cheap production cost, combined with the security to cope with even smaller beads that might arise in the future. An analysis of the production cost showed that the main cost drivers of the cold press process were the productivity of the machine and the lifetime of the mould. The purchase price of a machine is always important. However, a typical cold press production consumes about EUR25,000/year. Any kind of die cost saving would have a big impact on the cost effectiveness of the machine. The die costs are approximately 80% of the production costs.
Cost and productivity only one side of the coin Besides the die cost, the operator cost and the cost for scrap are important. That means that beside the sheer speed of the machine, the fast die change and setup is a major point, given that approximately one die is consumed each day. But cost and productivity is only one side of the coin. Easy and understandable operation, high consistency of the produced beads and overall superior quality of the beads have been other targets. On the basis of these results Dr. Fritsch developed the BCP 100, achieving enormous cost savings in the following:
PDi • Issue 4 • September - October 2012
• Very high speed • Very simple and therefore cheap die design • Very smooth operation to reduce die wear • Special filling shoe design to reduce diamond segregation • Compact design but still best access for service tasks • Flexible programming of different movements by operator • Big display and easy programme setup
The speed of the machine is dependent on the program used. Dr. Fritsch achieved a maximum speed of approximately 18 beads/minute. However, with higher speed, wear and temperature of the die increased. Therefore Dr. Fritsch recommend from an economical point of view a speed of 14 beads/minute. The machine has a maximum pressing force of 5t and capable of coping with normal mono-wire designs, but could also cope with the relatively small pressures that are required for thin multi-wire. As Dr. Fritsch has accumulated a lot of knowledge with hydraulic CNC-presses, the panel and some software modules of the KPV-series could be used. This includes also an optional router for the remote service that helps to update the PLC and panel software and to make service analysis easier.
Putting the Rotary Hammer Down In the US floor covering demolition contractors have long had their work cut out. Over the years, some new technologies have increased the efficiency of removing tile, hardwood and other tough floor coverings. However, there are still many applications that require contractors to get on their hands and knees, using a rotary hammer to slowly chip away the covering.
For Mark Jones, president of Commercial Tearout Services, and his crew, a large amount of time was spent on their hands and knees. Understandably, this took a toll on their bodies, as well as the company’s efficiency. Eventually, it led Jones to experiment with a new technology to speed up the process.
Floor demolition Based in Spokane, Washington, CTS has been in business for 16 years. Jones has a partner and, together, they have two parttime employees. The small company specialises in the removal of non-hazardous floor coverings, which basically includes all materials that do not contain asbestos. “We remove glue direct carpet, sheet vinyl, ceramic tile, vinyl composition tile and wood flooring,” said Jones. “Occasionally, we remove specialty floor coverings, too.” Like most other demolition contractors, Jones hopes that most of his jobs will allow him to use an electric powered ride on machine the company owns. The machine is equipped with a front mounted, 50mm wide carbide blade, which is designed to quickly knock up tile. However, the unit weighs approximately 900kg. Therefore, Jones is limited to using it on slab-on-grade floors and other levels that can be easily reached by elevator. Additionally, the machine is not well suited to manoeuvre in small rooms, despite its compact design. Jones’ main frustrations arose from a job at a local Air Force base where he was removing tile from a dormitory floor. “We’ve been removing tile at the dorm buildings over the last three years,” he said. “We’ve been awarded the contract every year.”
Light and powerful Unfortunately, the buildings did not accommodate the company’s equipment very well. Of the five floors in each building, only two of them could be accessed with the ride on machines. Therefore, Jones and his crew used hand held rotary hammers to remove tile from the remaining three floors. After taking up the tile with rotary hammers, the team would then run a diamond grinder over the area to flatten the surface. “There are about 370m2 of tile in each building and that’s a lot to do on your hands and knees,” said Jones. One day, Jones heard of a new type of tool carrier, claiming to offer a solution for this problem. The new tool carriers are designed to hold electric powered breakers rated in the 15kg to 20kg class, which offer the direct impact force needed to break through the bonding material between the floor covering and the surface. The carriers bear most of the weight of the electric breaker, taking the heavy burden off the operators and allowing them to work from a comfortable upright position. The units also offer easy adjustment of the blow force angle for achieving maximum effectiveness. The timing of Jones’ discovery worked out well, as he had an immediate need for the solution. “I was really looking for something because I knew we had another project coming up at the airbase,” said Jones. Luckily he was able to track down a rental store that had a CTS12 from General Equipment Company available for him to use. “The fact I was able to rent one first was a big plus. It made a major impact in our as it got everybody off their hands and knees and definitely changed the
whole game plan,” said Jones. He determined that the machine could remove tile at least twice as quickly as hand-held rotary hammers. “When we first used it at the base, I think we took up between 150m2 and 185m2 of tile,” he said. “The machine hits so much harder than a rotary hammer and, because of the way the breaker sits in the carriage, the operator doesn’t need to manhandle it. Also, being able to adjust the angle is equally important because the operator works at so many different angles to stay underneath the tile without digging into the slab.”
Saving the body In addition to working quickly, the machine offered ergonomic advantages to the crew. “It takes a lot of load off your knees and back, so an operator can run it for longer periods of time,” said Jones. “And because you’re standing up, it keeps your eyes and ears farther from the operation, instead of having your face 400mm from the floor.” Because of his success renting the equipment, Jones purchased his own CTS12 along with a Bosch 11335K electric breaker to use in it. Owning a CTS12 has allowed Jones to realize its full potential and understand the best applications for the product. “We’ve used it in areas accessible by ride on equipment, just to see how well it would work on different types of tile,” said Jones. “And there are times when the CTS12 is even faster to use than our ride on equipment.” Even after putting the machine to heavy use on multiple jobs, Jones still has some experimenting to do with the unit. Besides the airbase, he has used it in a hotel and a local spa, and would also like to try it on quarry tiles, because they are the toughest to remove.

Klenck goes for Volvo In the US Indiana-based demolition contractor Klenck Company is using Volvo Construction Equipment machines to achieve widespread success across the country. Klenck, which has a fleet consisting of seven Volvos, was founded in 2008 by husband and wife Tim and Angie Klenck. The company has since grown from small-scale projects to the Midwest’s leading commercial demolition enterprise. By joining forces with scrap metal recycling business Henry Fligeltaub Company, Klenck has secured contracts with many large corporations, and business is now spreading across the US and Canada. “We have a simple strategy to keep the costs down for our customers, and for
ourselves,” says Klenck president Tim Klenck. “By partnering with Fligeltaub we are able to salvage and recycle most of the building materials, benefitting our customers cost-wise and the environment by reducing the amount of waste that is sent to landfill.” A recent contract for Klenck was the demolition of the Emge Meat Packing Plant in Anderson, Indiana. Due to its location, Klenck was not allowed to use explosives during the demolition, so the various materials from the structure had to be sheared, moved, sorted, loaded and processed using machinery. Klenck employs operators from all over the US. “Because many live far away from the site, we work 10 hour shifts so they can have three
day weekends to visit their families,” says Tim. “Machine uptime is essential for us so that we can get the work done, correctly and on time. We only use Volvo machines because, for us, time is money, and Volvo’s service has always been timely and reliable.” The majority of demolition work on this project is carried out at height so providing operators with a comfortable working environment is extremely important. “Volvo machines offer our operators a comfortable ride,” says Tim. “The cabs tilt to 30°, enhancing visibility and reducing neck strain when working on high buildings. They can sit back and easily see what’s going on above and around them.” Forward and rear view cameras, projected onto the cab monitor, further improve allround visibility. The latest addition to Klenck’s fleet is a Volvo CE EC360C HR ultra high reach excavator featuring a boom that extends to 21m. Its attachments can be rotated 360° for when pulverizing, grappling, crushing and shearing. To boost machine utilization, a modular joint uses a hydraulic lock mechanism to change from high-reach demolition boom to a standard backhoe configuration in less than 30 minutes. “Our machines work 2,000 hours/year and not always on highrise projects. So being able to switch quickly and easily between standard and high-reach
booms is essential to keep things moving on site,” says Tim. Klenck currently owns three Volvo EC330B excavators, one Volvo L110E and L60F wheel loaders, one Volvo MC135C skid steer loader and the latest addition, the Volvo EC360C HR ultra high reach demolition excavator. “We don’t believe in micro-managing on our sites,” says Tim. “But we take safety very seriously and do all that we can to ensure operators are protected.” Klenck offers rigorous training and has a full-time safety officer on all of its sites. Operators carry out a hazard analysis before every job and site-specific training. And the company’s Volvo machines help to make their work even safer on site thanks to the special safety features built-into the machines. The Volvo EC360C HR has a framemounted falling object guard. Other protection includes bolted side-impact guards, heavy-duty double thickness side doors and bucket and boom cylinder guards help to protect the machine and its operator. The sound dampened cab also enhances operator comfort. “Our operators are very happy with the machines,” says Tim. “They often comment on the excellent visibility that Volvo machines, in particular, provide and the additional protection features help to keep our operators safe on site.”

First Doosan DX700LC in the UK demolition Industry In the UK demolition company Wring Group has expanded the company’s equipment fleet with the purchase of the first Doosan DX700LC 70t crawler excavator in the demolition industry.
The new DX700LC excavator was supplied by the local dealer, Kellands (Plant Sales) of Bridgwater in Somerset and joins the six other Doosan excavators supplied to Wring over the last 12 months.
Modified by Kocurek After modification by Kocurek of Ipswich, the new DX700LC excavator will form the base unit for a new super high reach demolition excavator, utilising a refurbished 37m long arm previously carried by a 65t base unit in the Wring fleet. The new high reach excavator will be the largest of the four high reach excavators in the Wring fleet. According Wring director Dean Wring, one of the main reasons for purchasing the DX700LC unit was the excellent service the company has received from Kellands and the high performance of the new Doosan DX380LC and DX225LC excavators recently purchased. “Our continued investment in specialist equipment means we own one of the UK’s biggest, most advanced demolition fleets with a complement of over 55 excavators and standard and high reach demolition rigs from 0.75t 90t and up to 37m reach, enabling us to undertake all manner of demolition and dismantling contracts,” said Wring Group director Dean Wring.
Demolition in Swindon The DX700LC has completed its first project demolishing buildings on the campus of the former Swindon College in Swindon. Wring is demolishing buildings at the Regent Circus site as part of a £50M project to construct a new superstore, eight restaurants and bars, a six-screen cinema complex and car park. Working on behalf of the developer, Wring has taken down the nine storey high-rise building at the centre of the former campus in stages using its new super high reach DX700LC demolition excavator. This type of demolition method was chosen ahead of other techniques as the site is in the middle of a residential area.
Largest in range Wring, established in 1926, has a long history of adapting to changes in the technology, culture and working practices of the demolition market. The group, regional offices in London and Exeter, has a reputation for providing fast and efficient services through a range of demolition, dismantling, decontamination and asbestos removal solutions across the UK. Kellands (Plant Sales), which has depots in Bridgwater and Camelford in Cornwall, is the Doosan dealer for the whole of South West England. The DX700LC excavator is the largest model in the Doosan range. The long carriage design, in combination
with the undercarriage extended to its maximum working width of 4m, offers optimum stability and safety in all kinds of digging, lifting, loading and demolition applications. The hydraulic system of the DX700LC is designed to provide exceptional performance with economic fuel consumption. A new mode control system provides optimum power and efficiency for all operating conditions. The load sensing piston pump and the closed centre valve enable fine metering of hydraulic flow for precise control of machine functions. Flow regeneration conserves energy and enables increased boom and arm cycle times. The DX700LC has a very spacious cab, equipped with ergonomic controls and instrumentation. Special attention has been given to keep noise to a minimum, which at the operator ear is 76 dB(A) while the noise level for bystanders is a low 107.7 LwA. Engine service intervals are 500 hours and the

DX700LC also shares the extended lubrication intervals of the Doosan excavator range. Lubrication is simplified thanks to a centralised front grease point, and the dipper arm grease inlets are grouped for easy access. The water trap and the engine oil filter are both located in the hydraulic pump bay, which is easy to reach from the ground level.

Extendable arms increase versatility of Bobcat compact excavators Compact equipment manufacture Bobcat, has increased the versatility of three machines with a new extendable arm option for the M-Series E42, E45 and E55 compact excavators. The extendable telescoping arm provides power and reach and should appeal to customers working in space-restricted areas, allowing more flexibility to clean out trenches and to place spoil further away from an excavation. Bobcat E42 and E45 excavators come with the extendable arm, a 610mm range of motion, with maximum dig depths of 3.8m and 3.9m, respectively. The extendable arm option includes an additional counterweight. The Bobcat E55 excavator with extendable arm option has a 760mm range of motion and a maximum dig depth of 4.45m and approximately 580mm more dig depth than an E55 with the standard arm configuration. The Bobcat extendable arm is the industry’s only clamp-ready extendable arm compatible with the clamp attachment and the Hydraulic X-Change mounting system. With this the extendable arm maintains the versatility of operating multiple attachments. A retention pin holds the arm in the retracted position, allowing use of up to16 different attachments. The extendable arm cylinder is operated through a rocker style thumb switch located on the joystick.
Atlas Copco’s new SB 702 solid body hydraulic breaker Atlas Copco has added the SB 702 hydraulic breaker for a range of gardening, landscaping, construction and demolition jobs. Research and product development has resulted in lower fuel consumption, lower vibrations and less noise. The unique aspect of the SB 702 is its solid body, a feature that no other breaker in the 700kg class has, the company claims. A single piece housing construction makes the SB 702 unusually compact and easy to handle. The percussion mechanism and guide system are integrated into a single block of steel, eliminating the need for side bolts. The integrated, maintenance free accumulator is easily accessible yet well protected from bangs and knocks. The SB 702 works with a wide oil flow range
and can therefore be installed on a broad variety of carriers. In case of hydraulic overload, the SB 702 is protected by an integrated protection valve, which prevents damage to the breaker, and helps avoid downtime. The SB 702 is easy to set up and requires very little maintenance and easy to service. Double tool retainer bars minimize stress and wear on the working tools. Changing the working tools is easy thanks to the patented retainer bar lock system, and the floating lower bushing can be replaced by the operator on site with standard hand tools. Thanks to energy recovery, the SB 702 provides much higher percussive performance. While the impact energy remains constant, the breaker increases the blow frequency, which increases percussive performance. This, in turn, increases efficiency, and enables higher productivity with lower fuel consumption. Energy recovery also helps to absorb recoil, which means less wear and tear on the carrier and a higher level of comfort for the operator.
New Doosan Excavator Doosan Infracore Construction Equipment has launched the new Stage IIIB compliant DX380LC-3 large crawler excavator in the 34t to 42t market segment. The new excavator offers as standard several features including improved visibility, comfort, controllability and ease of operation. A new joggle/shuttle control is a worldwide exclusive feature on new generation Doosan excavators, the company claims. The DX380LC-3 is intended to handle a broad range of applications, such as heavy earthmoving, road building, civil engineering, demolition, quarrying and large scale material-handling. It is powered by the Doosan DL08K six cylinder turbocharged diesel engine meeting Stage IIIB

engine emission regulations through the use of exhaust gas recirculation and diesel particulate filter after-treatment technologies. Combined with an 8% increase in torque, the engine delivers 5% more power of 213kW at 6% less speed 1800 revs/min. The excavator offers a claimed 22% increase in the productivity to fuel consumption ratio. The overall reduction in fuel consumption is due to a combination of features including lower engine speed; improved cooling efficiency with the oil cooler separated from the radiator; the new ECO gauge providing fuel consumption guidance for the operator; improved main control valves reducing energy loss and increasing efficiency and additional sensors for improved electronic management of pump/engine/ mcv. This allows a more efficient selection of flow/pressure/revs/min to better match load requirements. A new hydraulic system with a new electro-hydraulic control minimises pressure loss through the main control valve, thereby utilising engine power more effectively, maximizing pump usage and delivering more comfort, smoothness and accuracy. New hydraulic pumps and valves increase main pump flow capacity by 23% and pilot flow has been increased by 11%, boosting front, travel and power functions. A 5% increase in hydraulic pressure improves performance with higher lifting capabilities, faster cycle times and higher breakout forces. At 6m reach at ground level, front lifting capacity has been increased by 15%, while lifting capacity over the side is up by 3%. The bucket digging forces have also been increased by up to 6%.
New Gehl compact excavators The five new Gehl excavators Z17, Z27, Z35, Z45 and Z80 are powered by Yanmar engines combined with a hydraulic system to enhance performance. All five are zero-tail swing machines, eliminating cab overhang beyond the tracks in all directions and allow operation directly against a wall
or other obstruction without causing damage to the structure or machine. The four larger models are equipped with a hydraulic quick coupler, making attachment changes simple. A full line of EDGE attachments is also available, including buckets, hammers and breakers. “The Gehl compact excavator product offering meets the demand we have recognized in the mini-excavator market,” said Gehl compact excavators product manager Nathan Ryan. “Consumers are looking for more zero-tail-swing models in the 1.7t to 8t capacity range than ever before. The new Gehl compact excavator model range suits the reach, dig depth, and lift capacity needs of builders, landscapers, general contractors, plumbers and excavation crews.”

Russia’s Concrete Sawing & Drilling Association is formed The Russians have done it as the country’s National Association of Concrete Drillers and Sawers is now a reality. This is very good, if somewhat unexpected, news. It appeared that after about ten years of sparse meetings and fruitless discussions the idea of a national association in Russia had all but fizzled out. But the Russians have the time honoured tradition of snatching victory out of the jaws of defeat. Andrei Bushmarin reports from Moscow.
The fact that it has taken so long for the country to start the association should not surprise anybody as uniting around a cause is not generally a Russian thing. Having said that, it would be fair to point out that establishing a trade association is an uphill job anywhere, as Russia’s European and North American counterparts would readily confirm. But this being Russia, its path to a national concrete cutting union was merely strewn with false starts and setbacks.
Fair try already in 2007 The closest the Russians came to establishing an association in the past was in 2007 when owners and top managers of about 10 companies, both contractors and suppliers, gathered in a conference room at the Bauma trade show to discuss the prospects of such an organisation in the country. At the time, the chief campaigners for the association were Andrey Kossolapov, the owner of Moscow based Spetzmontage, and Yury Mokin, the late co-founder of Olvex, once Europe’s biggest concrete cutting contractor. The meeting was conducted in the presence of the representatives of the International Association of Concrete Drillers and Sawers, Concrete Sawing and Drilling Association and German Fachverband Bohren und Sägen and left most of the delegates, particularly the international ones, with the impression that the creation of Russia’s national association was imminent. In the wake of the meeting, PDi ran a story about the first step being taken towards a Russian association. Little did they know that it would take another five years for the association to materialise.

they were all but crushed by the 2008 economic meltdown. The association issue slipped way down the list of players’ priorities and remained there until 2011 when the Russian industry regained most of its pre-crisis shape. The recession, however, took its macabre toll, claiming the life of Yury Mokin who passed away in December 2009. That was the time when prospects of creating a civilised marketplace for concrete cutting services in the country seemed just as real as Russia’s national football team winning the World Cup. But Andrey Kossolapov refused to give up. Joined by a few other enthusiasts, like Maxim Petrov, the managing director of St. Petersburg based supplier DUS, he continued to advocate the benefits of an association to Russian players. Their efforts finally bore fruit on 7 July 2012 when the founding congress of Russia’s National Association of Concrete Drillers and Sawers was held. About 40 delegates attended the congress from four federal districts of Russia. The venue, the Moscow State University of Civil Engineering, was chosen rather appropriately. Predictably, delegates from Moscow and Petersburg prevailed, but the meeting also saw participants from Russia’s lesser-known towns like Tolyatti and Balashiha. Some even came from as far as Krasnodarsky Krai, the southern part of Russia bordering the North Caucasus. As delegates went through the agenda, one could not help but notice that suppliers seemed more wary of the association’s benefits than contractors. In the rest of the world, it is usually the other way around where suppliers, who need clear rules to play by, tend to take the initiative. But that is just another telling example that Russia works in mysterious ways. What matters most though is that the national association was established. The longstanding efforts of Andrey Kossolapov, the association’s most stalwart champion, were rewarded with

New Dustboss model In the US Dust Control Technology introduced its largest DustBoss DB-100 at the MINExpo 2012 trade show, held in Las Vegas in September. The new dust suppressor has a range of more than 100m, giving it ample reach to cover material stockpiles 60m to 90m high and an area of more than 26,000m2 from a single location. The DB-100 was designed with input from some of the leading mining companies in the world, with data collected from numerous site visits, where visibility around working areas can be profoundly impacted by dust. “Most operations use water trucks to wet down haul roads before trucks enter the area for loading,” said DCT vice president Aaron Valencic. “Unfortunately, the technique is only marginally effective on surface dust, and it has no effect at all on airborne particles. Water trucks also don’t address dust from the loading operation itself, as their reach is limited only to the area around the driving surface. This new unit will reach all the way to the working face, knocking down dust from the shovel as it picks up or drops material.” According to CEO Edwin Peterson, the unit was developed specifically for large-scale mining, coal operations and bulk material handling. “It was originally an idea of our late co-founder, Barry Brown,” said Peterson. “He had the vision to create a mine-grade open-pit dust suppression design that was extremely powerful and exceptionally reliable. Although he didn’t get to see it built, I know he’d be proud to see it become a reality.” Peterson said that in applications such as mining, which require high dependability even under extreme working conditions, the simplest designs are usually the most successful. “During the design phase, we talked with mine managers, maintenance staff and supervisors to see what was most important to them,” said Peterson. “The range and performance were key, but nearly every one of them also stressed reliability. Downtime is very expensive, and they want to spend their days on core activities, not dealing with equipment breakdowns.” To address that need, DCT engineered an extremely rugged and
efficient design. Like all of the company’s fan-driven atomizers, the DB-100 delivers both power and dependability by using a straightforward, direct drive fan motor. It has no drive belts, diesel engines or complex worm gear systems that could present breakdown problems in the difficult service environment of a mine or coal yard. Despite its impressive size, the DB-100 requires minimal maintenance, with lubrication of fan motor bearings recommended every 10,000 hours, while the oscillation motor is lubricated for life. All DustBoss models are covered by an industry-best 3-year / 3,000 hour warranty and complete satisfaction guarantee.
Prototype Proves Successful DCT made the announcement recently after extremely positive trials at a large coal handling operation, where migrating dust was creating a nuisance. The DB-100 demonstrated its effectiveness in managing dust from the facility’s stockpiles, which had proven too large for a competitor’s dust suppression equipment previously tested by the utility. The new design represents the culmination of two years’ development time, and is based on 40 years of engineering experience in atomized mist technology. “Effective dust suppression is a complex equation,” said Peterson. “In addition to droplet size and air speed, there are dozens of variables that affect a machine’s performance. The size and precise shape of the barrel are critical, for example, as a successful design must control the laminate air flow to achieve the optimal plume and distance. “But the design really is the sum of all its parts, in that every component is specifically engineered to maximize performance. That includes the integrated fan and nozzle components, inlet valves, propellers, vanes, pumps and filters. Failure to optimize any one of those details will detract from the unit’s effectiveness.” The new machine’s 60 HP fan is fed by a manifold of 30 brass nozzles that are specifically sized and positioned for the new design. The DB-100 features simple, user-defined 359º oscillation, along with adjustable elevation from 7º to 45º. It can also be outfitted with a dosing pump to accurately meter in surfactants or tackifiers to further enhance binding of dust particles. A 7.5 KW booster pump elevates water pressure as high as 13.6 bar for outstanding droplet production, and the DB-100 can be set up to run potable or non-potable water. A wye delta starting system reduces initial energy requirements, and DCT recommends a minimum of 0.69 bar water pressure. The units include an in-line filter and 37 mm camand-groove quick disconnect female coupling. They can be ordered with international motors to meet standards for any location around the world. Because it can run unattended for long periods, the DB-100 can free up manpower and equipment by eliminating the need for water trucks or sprinklers, delivering a short payback period for many users. The versatile device is also well suited to automated control, and can be wired to operate according to a wide range of sensor inputs, including weather conditions and even specific air particulate levels. Any DustBoss is available with the company’s proprietary Variable Particle Sizing technology, providing

The first DB-100 production model was available for sale at MINExpo 2012, with all profits from that unit donated to the Illinois CancerCare Foundation in honour of Barry Brown, a founding partner of the company who lost his battle with cancer in 2010. The Illinois CancerCare Foundation, in collaboration with Illinois CancerCare, helps bring the latest nationally renowned clinical cancer research trials to central Illinois. Recognized in 2007 by the American Society of Clinical Oncology as one of the top 10 community research centres in the U.S., Illinois CancerCare delivers leading-edge patient care and participates in nationwide research to help further the battle against cancer and blood diseases. Dust Control Technology is a global leader in dust management solutions, with expertise in mining, coal handling, steel, ports and shipping, scrap, material recycling and demolition. The company specializes in atomized mist technology, with its entire focus on atomized misting equipment for dust suppression and evaporation. All of the firm’s R&D, experience and expertise is centered completely around those applications, and its staff helps customers analyze particle sizes, working environments and other factors to ensure effective performance under real-world conditions. The units are far more effective and efficient than manual spraying, with some customers realizing payback in less than six months. DCT equipment carries the industry’s longest warranty, and can be purchased outright or rented from an extensive fleet of dust suppression equipment.

The Real Demo When demolishing very tall buildings, high cranes with wrecking balls can still be the most efficient and safe solution. Even though there are many special high-reach excavators with demolition tool attachments, safety issues can still be a critical for high reach machines. PDi looks at the method of using cranes and wrecking balls, and presents some of the well known, international manufacturers of cranes that can be used in demolition applications. Mikael Karlsson reports.
Demolishing big buildings by large cranes and wrecking balls is one of the oldest demolishing techniques. The method was mostly used during the 1950s and 1960s. But is still used and mainly in the US, to demolish high brick concrete buildings. Also in Europe we can see cranes and wrecking balls used to demolish, for example, high chimneys and silos.
Also for logistic purposes
specialist machinery, which it develops in conjunction with its customers. Currently more than 70 sales and service partners represent Sennebogen, covering most of the world. The Sennebogen Group has over 1,000 employees and has a turnover of EUR310M.
Liebherr Hans Liebherr established his family business, Liebherr, in 1949. The success of his first mobile, easy-toassemble and affordable tower crane was the foundation on which the company flourished. Over the years, the business has expanded and grown to include mobile cranes, crawler cranes and other machinery, like hydraulic excavators, dumper trucks and wheel loaders. The Liebherr Group, with more than 35,000 employees and 130 different companies all over the world, is one of the world’s leading manufacturers of construction machinery, and also one of the largest, worldwide suppliers of a wide range off cranes for the construction industry. With the LR series, Liebherr offers a range of lattice boom crawler cranes. In the class below 300t, low transport weights, rapid self-assembly, optimum load capacities and comprehensive operating information are among the cranes’ main functional features. For its larger crawler cranes with lifting capacities up to 1,350t, Liebherr also offers a wide range of multifunctional jib systems. These cranes can reach heights of up to 223m at the hook and working radii of up to 152m, but retain their manoeuvrability thanks to innovative solutions for the handling of extremely high ballast weights. The LR series is completed by the hydraulic duty cycle HS series of crawler cranes, which have been developed for diverse material handling operations. The six model range has load capacities between 35t and 200t.

Ola Månsson in his speech to the winners and the dinner guests.
The awards were divided into 10 different categories and were initiated by the Swedish magazine Professionell Demolering, sister publication to Professional Demolition International. The awards are given in co-operation with the Swedish Construction Federation and the Swedish associations for Demolition, Recycling and Clearance and Concrete Sawing and Drilling.
Ten different categories
The sought after awards.
In total 10 different awards were presented in the following categories: Demolition Contractor of the Year, Concrete Sawing & Drilling Contractor of the Year, Demolition Project of the Year, Concrete Cutting Project of the Year, The Safety and Working Environment Award, The Recycling & Environmental Award, Manufacturer/Supplier of the Year, The Great Innovation Award and finally Honorary Awards. About 15 nominations where submitted to compete for the different categories. This was a good start, as Swedes normally do not like to make a fuss about their work with. Some companies where nominated for more then one award. The management of the magazine Professionell Demolering and the award jury decided the honorary awards. The award jury was chaired by editor-in-chief Jan Hermansson and included another 10 well-known personalities with many years of experience of the Swedish construction, demolition and concrete cutting industries. “I am amazed how well this initiative was received by our industries. People really lightened up, stretched their backs and showed that they were very proud of being part of these industries,” said Swedish Construction Federation engineer Lars Sandström, who is closely involved in the Swedish associations for demolition and concrete sawing and drilling.
Jan Hermansson, editor-in-chief for the magazine Professionell Demolering, organiser of the awards.
Over 250 guests gathered in the Scandic Hotel InfraCity ballroom for the prize giving ceremony. Master of ceremony was Jan Hermansson and the awards were presented by the Swedish Construction Federation’s president Ola Månsson and Lars Sandström. The prize giving started with the nine honorary awards. The first awards were given posthumously to three individuals who had worked in the Swedish demolition and concrete cutting industries their whole lives and who passed away

recently. Bror Österman was one of the first concrete sawing and drilling contractors in Sweden and also an inventor of concrete cutting equipment. Kjell Larsson had also dedicated his life to working with concrete sawing and drilling as well as demolition and recycling and was one of the founding members of today’s associations. Mats Johansson was one of the great inventors of this industry and his products are now well known all over the world. Mats developed numerous machines, particularly for cutting and most contractors are probably familiar with the ring cutter. Representatives from their families collected the awards. Honorary awards were also presented to Owe Persson who is one of the founding fathers of the Swedish concrete sawing and drilling industry and a well-known inventor of machines and systems aiding concrete cutters. Svend M. Andersen from Andersen Contractor has been working in this industry for about 50 years. For the last 25 years he has been dedicated to supplying the Swedish demolition, recycling and scrap industries with machine and tool solutions making everyday work easier for contractors. An honorary award was also given to the president of Husqvarna Construction Products Anders Ströby for his devotion, energy and drive to introduce innovations in the field of concrete sawing and drilling. It is unique that a person in his position has such an in-depth knowledge and interest in the technical details and functions of his company’s products. The last two honorary awards were given to two unique product developers, HTC Sweden’s founder Håkan Thysell and the founder of the Pentruder equipment Anders Johnsen. Håkan Thysell has brought a completely new working field to this industry in his method and range of machines for concrete floor grinding and polishing. Others have followed his example. In a similar way Anders Johnsen has brought a completely new way of thinking in terms of concrete sawing and drilling. His systems combine thinking, electronics and mechanics, offering contractors increased efficiency and smoother and better working situations. The award Concrete Sawing and Drilling Contractor of the Year was given to the contractor Arnesson Betongborrning. For over 30 years Arnesson has succeeded in safeguarding its knowledge and skills and developing them and the company into a successful nationwide concrete sawing and drilling contractor. Demolition Contractor of the Year was given to the Stockholm based company Rivners, which has been in business since the 1950s. The award for Manufacturer/Supplier of the Year was given to Brokk. The company started to develop remotely controlled demolition robots in the 1970s, long before today’s advanced machines and tools for demolition. It was a groundbreaking method that would carry out demolition work far safer and more efficiently, and in some areas where it would have been impossible without this system. The manufacturer has in the past decade expanded its range of new models and applications. Concrete Cutting Project of the Year was given to the company A-Borrning for the accuracy and professionalism they
PDi • Issue 4 • September - October 2012
performed when carrying out one of the more extensive and complex drilling projects. Demolition Project of the Year was given to the company Betongborrargruppen – Rivning – Sanering – Håltagning. The citation indicated that the company had showed great knowledge and professionalism in a very unconventional and complex demolition project at the Stockholm Central Station, right in the middle of the capital. A variety of demolition methods were used and also to a great extent concrete sawing and drilling methods. The Recycling Award – Demolition was given to the Gothenburg based company Rivab, part of Lotus Demolition. The prize was given for the long-standing, extensive expertise and professionalism in demolition and recycling and to the careful demolition, dismantling and preservation of an historic building in Gothenburg. Safety and Work Environment Award was given to Arnessons Balkongsågning (Balcony Demolition) for the many years of entrepreneurship, awareness and responsibility to improve working practices in a precarious working environment and with great knowledge and ingenuity. Special recognition was given to its new type of patented rig for safe balcony demolition. The Recycling and Environment Award went to Jerneviken Maskin for the introduction of the Slurrybox onto the Swedish market. The Slurrybox converts concrete slurry in to fresh water, eliminating the hazardous concrete waste and packing it in to small dry briquettes. The Great Innovation Award was given to Tarpaper Recycling for its innovation of reducing the amount of construction waste sent to landfill and using it instead as a recycled component in the production of new road materials.
Next Awards in 2014 The Swedish Demolition Awards received a lot of attention in the media in Sweden. The winners also used the awards to promote their individual company’s activities. The next Demolition Awards ceremony will be held during the next DEMCON, 4-5 September 2014. “We couldn’t imagine that we would get such a positive response for the awards. Swedes are normally quite reserved about their achievements and activities. Many contractors also hold back information about their jobs in order to avoid competition,” says Jan Hermansson. “But I think Swedes should be proud of these industry awards. We have many fantastic inventors and many skilled contractors and the Swedish Demolition Awards are a reflection of this. I also want to direct a special thanks to the members of the jury who have done a terrific job and in a particular to Ola Månsson and Lars Sandström from the Swedish Construction Federation who have supported the awards in a very strong and devoted way.”

NEW WOR ON WH Intermat has lived up to the demolition industry’s expectations by providing a launch pad for numerous new products. The manufacturers of wheel loaders put on particularly impressive displays. PDi’s Andrei Bushmarin reviews latest innovations in the wheel loader segment.
Judging by the number of new launches at Intermat, manufacturers of wheel loaders are not afraid of the second wave of the recession, which is widely expected in 2013. And they might be right, considering that wheel loaders are probably one of the most universal types of machines ever designed. Agriculture, forestry, mining, road building, demolition, material handling, are just some of the industries where wheel loaders have already proved their worth. Recession or no recession, ore must be mined, roads must be built and demolition debris must be taken away. All these tasks cannot be effectively accomplished without using a wheel loader, the industry’s most reliable workhorse. Fortunately many manufacturers have them in their range of products.
New smart loader from Komatsu Komatsu Europe used Intermat to unveil its new wheel loader WA380-7. With a net power of 142kW, the WA380-7 is powered by the EU Stage IIIB/ EPA Tier 4 interim compliant Komatsu
PDi • Issue 4 • September - October 2012
SAA6D107E-2 engine. Weighing in at 18.1t, the new model has lower fuel consumption, while boasting enhanced performance, serviceability and operator comfort. The WA380-7 is equipped with the latest Komtrax fleet monitoring system, which sends data, such as working hours, fuel consumption, location, cautions and maintenance alerts to a secure website using wireless technology. The Komtrax system increases machine availability, reduces the risk of theft and allows for remote diagnosis by the distributor. The upgraded engine features a few enhancements on its forerunners, including a hydraulically actuated Komatsu variable geometry turbocharger and an exhaust gas recirculation valve. Another improvement is what Komatsu calls SmartLoader Logic, which automatically adjusts engine torque to the job conditions. The torque converter with the lock-up function contributes to greater acceleration, higher top speed, better hill-climbing capability and lower fuel consumption. The lock-up function activates in the 2nd, 3rd and 4th gears and gives the machine a maximum speed of 40km/h.
A host of safety features on Cat’s mid-range Operational reliability and availability of Cat’s K series of medium wheel loaders, first introduced in 2011, have been boosted with a host of new features. They are engineered to keep the wheel loaders from damage in harsh industrial applications. First off, the machines’ steel front fenders fit close to the frame to help avoid damage, while the bottom and rear access steps are suspended by steel cables. The front frame guards protect the underside of the machine’s front half from debris accumulation and damage to the drive shaft and lift cylinders. The belly guards prevent debris build-up on the rear section’s
RKHORSES HEELS underside, thus safeguarding the engine and transmission. The axle seal guards provide protection from wire or other debris that could wrap around the axle and damage the axle seals. An optional heavy-duty radiator guard provides additional protection of the machine’s rear end. There are three versions of cab protection available, which are two front windshield guard options and a full cab glass guard.
Volvo focuses on fuel efficiency and performance Volvo CE features the G series led by the L220G wheel loader that has won the Red Dot product design award for its fuel efficiency and performance. The series ranging from 8t to 35t models is complete with Volvo’s Tier 4 Interim/Stage IIIB emission-compliant engine that has high torque at low engine speeds. Furthermore, the machines boast Volvo’s patented Torque Parallel linkage system, which combines Z-bar and parallel linkage to offer high breakout force and stability throughout the entire lifting range. New to the Tier 4i range is a diesel particulate filter that traps and holds exhaust particles, which are later incinerated and turned into non-toxic CO2. The G-series also reduces emissions on the move thanks to Volvo’s eco pedal. This new feature uses pushback force to remind the operator not to use excessive pressure on the accelerator pedal, contributing towards lower fuel consumption.
SCR engines on NHC and Case loaders The NHC group that owns the two brands Case and New Holland Construction used Intermat as a showroom for a host of new wheel loaders. Despite different brand names, Case’s 521F and 621F and NHC’s W110C and W130C have a lot in common. For starters, they are all powered by Tier 4i engines. To meet this standard, the selective catalytic reduction technology is utilised. This technology, optimising fuel combustion, has been de-
veloped by FPT Industrial specifically for construction applications and was first tried on trucks in 2004. High combustion temperatures result in low fuel consumption and high engine output. In addition, this SCR solution does not require a diesel particulate filter, further optimising machine uptime and operation costs. Fuel waste is also reduced to a minimum by the Ecostop feature, which automatically shuts down the engine and the electric system after five minutes of idling. Another common trait is heavy-duty axels, with the possibility of 100% differential lock on the front one.
JCB updates wheel loader line-up Following the introduction of the JCB 457 flagship wheel loader earlier this year, the UK-based manufacturer is now launching two new machines, the JCB 427 and JCB 437 that will replace the outgoing 426 and 426 models. The JCB 437, which was previewed at Intermat, and its smaller brother, will go into production in the autumn. Both loaders are powered by a 6.7 litre Cummins QSB engine, which is Stage 3B compliant without using a diesel particulate filter or selective catalytic reaction. Besides the variable geometry turbocharger, the engine houses a high-pressure common rail fuel injection system, exhaust gas recirculation and diesel oxidation catalyst. As standard, the machines come with a ZF four-speed transmission. An optional five-speed power transmission is also available. A lock-up torque converter on the five-speed box activates in gears 2-5, reducing losses from the transmission. This function allows higher efficiency on hill climbing, loading and carrying duties. Another standard feature is a smart clutch cut-off system, which disengages the clutch to limit tractive effort when loading trucks or negotiating tight corners. Redesigned stylish cab with a new full-colour LCD display completes the list of improvements.

DEMCON now fully established Again the Nordic demolition show DEMCON was a success and the date has already been fixed for the next DEMCON in 2014. The suppliers were there and the right people came and made their purchases directly on the show floor. The show is now considered fully established and attracted 55 exhibitors and 2,650 professional visitors during the two days.
The second edition of the Nordic demolition show DEMCON was held recently in Stockholm. This small and niche exhibition, covering two days in September, attracted about 55 exhibitors and around 2,650 industry professional visitors.
The quality - not the numbers! “I am very satisfied. We had a great amount of visitors testing machines and making business directly at the show. That is exactly how it should be,” said DEMCON site co-ordinator Arne Holgersson. “At this show, and it has always been like that, it is not the amount of people we count. It is the right kind of people we want to visit the show. And this year really the right people came from all over the Nordic region. DEMCON has truly been established now.” The visitors were quite geographically spread. Mid Sweden with the grand Stockholm area was of course dominant, but visitors came from the north and the south of the country. About 15% of the visitors came from the other Nordic countries Norway, Finland, Denmark and the Baltic states. There were
PDi • Issue 4 • September - October 2012
Issue 4 • September - October 2012 •
also quite a number of visitors from the rest of Europe, Russia and some really long distance visitors from Asia Pacific, United States and South America.
Nordic final in Tyrolit Cutting Pro Competition The show opened on Thursday 6 September. First day saw a constant flow of visitors. Tyrolit organised the Nordic final in the Cutting Pro Competition, which was a popular point on the show programme attracting many visitors to the show as well as the finals itself. Winners of the Nordic Final who will represent Norway, Denmark, Finland and Sweden in Innsbruck in 2014 were: Elvis Anakjev from Drillcon in Norway won with 73 points. In second place with 72p was
PDi • Issue 4 • September - October 2012
Lars Nielsen from MT Höjgaard Alborg in Denmark. In third stop was Gerd Daus with 69p representing Norwegian company Rune Monsen. Besides these contestants the Swedes André Bellander, 62p and Magnus Johansson, 57p and the Finns Ilpo Laakso, 58p and Wesley Aarnio, 48p will also be competing in the final in 2014. The winner of the Tyrolit Cutting Pro Competition in 2011, Joakim Lenander, will also compete in the final in 2014. Joakim had 68p at the Nordic final in Stockholm.
The DEMCON Party The DEMCON show closed at 6pm in time for the DEMCON Party with about 250 guests and included the Swedish Demolition Award ceremony. (See page
48-49 for details of the awards).
Really crowded on Friday Friday was, as predicted, the busiest day and several busloads of contractors attended. “I want to direct a special thanks to those contracting firms and their owners who decided to invite a large part or all of their employees to visit DEMCON. It is a big investment in their personnel that I am sure will pay off,” said organiser Anita Hermansson. “We had many busloads of contractors coming both on Thursday and Friday. Firms with 30 to 80 employees and in some cases over 120 people were taken to the show by their employers. It is really impressive and hope they all found it interesting and enjoyed themselves and that the visit was worth the investment.” Friday was a very busy day and both the indoor and outdoor areas were crowded. Outside there were a number of equipment demonstrations by several exhibitors, including Hilti and Husqvarna, and the Tyrolit area where the competition took place.
The outdoor sector In the out door area nearly all the brands of concrete sawing and drilling equipment and diamond tools in Scandinavia were represented. Tyrolit had a big booth
in the centre of the exhibition hall as well as their out door area. All latest products were on show, such as the latest wall saw, drill systems, wire saws and diamond tools. Husqvarna Construction Products also had two booths. Inside the full range was displayed, including the new diamond blade series Diagrip 2 and claimed by Husqvarna to be the fastest cutting blade ever. In the outdoor booth Husqvarna demonstrated their equipment including wall saws, drill systems and floor grinders. Also Hilti displayed their full line of products for professionals with a booth inside and a demonstration area outside with their popular drill systems, wall and wire saws. In particular their line of rotary drills and jackhammers were frequently tested. Nearby outside Swedish company Matek were displaying and demonstrating ICS chains saws. A Swedish distributor showed Gasparin mobile crushers and material handlers from Atlas along with dust cannons from WLP. Arnessons Balcony Demolition showed new and patented systems for demolition of balconies that also received recognition in the Swedish Demolition Awards. Atlas Copco Construction Equipment also had booths inside and out showing their lighter equipment inside and outside displaying their full range of heavy-duty attachments, like hydraulic breakers, pulverisers and concrete crushers. A rather new player on the demolition arena that had a large outside booth was OP Systems. The company has been around for a long time but about a year ago decided to focus also on demolition. At the time they became distributor in Sweden for mobile crusher manufacturer Rubble Master and just before the show they announced that they were also representing Dutch demolition and recycling attachment manufacturer Demarec. OP is also distributor for Sennebogen material handlers. Some other companies outside were Inomec, Strengbohm Eneby, dealer for Wacker Neuson
and Weidemann. Swedish specialist hydrodemolition contractor E-Schakt displayed their systems and robots for hydrodemolition outside and inside. As there was a lot of concrete sawing and drilling going on outside all concrete slurry was dumped into the Gölz smart slurry handler, the Slurrybox that is sold in Sweden by Jerneviken Maskin. Also the Slurrybox received a special prize at the Swedish Demolition Awards.
Demolition suppliers side by side In the exhibition hall suppliers of concrete sawing and drilling equipment and diamond tools were dominant, but there was also quite a number of suppliers of demolition equipment. Andersen Contractor showed Trevi Bennes equipment, which is popular among Swedish demolition contractors. PG Export displayed equipment from Arden Equipment and Caterpillar through their Swedish distributor Pon Equipment showed parts of their range, in particular their new smart quick coupling system for easy change of attachments. The Swedish demolition attachment brand SMC, used by many Swedish demolition contractors, also displayed their products in an indoor booth. SMC also received a lot of attention for the new rotary milling heads. Next to SMC the company MTT Sweden showed a new heavy hammer and the crushing bucket REMU. Furukawa and VTN Europe were also represented
Issue 4 • September - October 2012 •
The Hydrodemolition Square There was also a special section of the exhibition hall dedicated to hydrodemolition equipment. Two of the world’s biggest hydrodemolition equipment manufacturers, Aquajet Systems and Conjet, were represented along with two of their clients, E-Schakt Entreprenad and Waterjet Entreprenad. Next to the hydrodemolition section the Swedish branches of the Concrete Sawing and Drilling Association and the Demolition Association, had their meeting point.
The concrete cutting equipment suppliers
through their long time distributor Amas Svenska. And Swedish distributor of Ramtec/Robi, Entrack, showed a few attachments from the lines. Entrack is also a manufacturer of different types of attachments. Demarec were well represented at DEMCON. RF System, owned by Kinshofer, displayed Demarec attachments together with some of their own equipment, as well as equipment from Kinshofer. Montabert, for a long time the number one breaker brand used on demolition robots, has got a new distributor in Sweden called Maskinia. Maskinia has a close relation to the Swedish demolition and recycling industries and is the perfect solution for Montabert to get out to demolition contractors. Maskinia had a small booth showing both Montabert breakers and Everdigm, which has been a brand with the company for a long time. Just before the start of DEMCON the Dutch company Hydraram announced that they would attend the show in order to find distributors in the Nordic region. Hydraulic equipment needs oil and maintenance and that is something that the company Hydroscand is aware of selling all components necessary to make work smooth and easy. A broken hose needs to be fixed right away and Hydroscand are always nearby, being the number one player in this field in Sweden.
There were a lot of manufacturers and suppliers of concrete cutting equipment and diamond tools at the show. In addition to those already mentioned, others included Jerneviken Maskin selling different types of machines, systems and aids to improve every day life for concrete cutters. Jerneviken also have their own manufacturing of diamond blades and core bits. The company is also the first to manufacturer diamond tools with positioned diamonds in Sweden. Jack Midhage, a similar supplier to Jerneviken, also had a wide range of machinery and equipment for concrete sawing and drilling. For Midhage the rental industry is quite a large client sector. Tractive with its brand Pentruder was showing all of its latest additions to its lines of wall and wire sawing and core drilling equipment. An emerging company in central Sweden and in particular in the Stockholm area is Swedish Diamond Tool Consulting. Its employees have experience from working in the field as the two owners come originally from Hagby Bruk, later named Hagby Asahi and a Swedish manufacturer of diamond tools. The diamond tool section was sold to Husqvarna about 10 years ago. SDC is now the distributor of Arix diamond tools in Sweden, Savi floor saws, Lissmac, Dibo and Pullman Ermator. Sole suppliers of all sorts of diamond tools and exhibiting at DEMCON were the Uppsala based company Slikab and the Stockholm based OX Tools. There were also some other exhibitors that were testing the Scandinavian market instead of going
PDi • Issue 4 • September - October 2012
through distributors. Dr Schulze from Germany attended DEMCON and displayed some of their latest products. Their new high cycle plunge saw had its world premier at DEMCON. Dr Schulze has a wide range of machines for concrete sawing and drilling and floor grinding as well as a large range of diamond tools. Another manufacturer of diamond tools Fuzhou Skystone Diamond Tools from China also exhibited some of its products. Next to Skystone Italian manufacturer Diamond Pauber displayed their range of diamond tools. Diamond Pauber. It was the company’s second time at DEMCON.
Concrete floor grinding and polishing equipment Concrete floor grinding and concrete floor polishing are common services among Scandinavian concrete cutting and demolition contractors. These services have been a natural part of the work for at least two decades since Håkan Thysell launched his new method. HTC Sweden was present at DEMCON showing their latest standard and edge grinders along with their own dust extractors for concrete floor grinding and polishing. Also another well-known Swedish manufacturer, Scanmaskin, displayed their latest grinding machines for concrete and wooden floors. Scanmaskin also displayed a new line of diamond segments. The company Swediatec, a subsidiary of Jerneviken Maskin, also showed their wide range of floor grinders, as well as their own diamond tools. Floor grinding equipment is also part of Husqvarna Construction Products’ range and was also on display in their booths. The company also showed their most recent grinder, which is the smallest model in the range.
Taking care of dust and slurry There was also a strong representation of manufacturers and suppliers of equipment for dust extraction, air cleaning and concrete slurry containment. Most of them quite are well known in the industry, with the exception of Sila. The company is new but not the people behind it. Sila’s line of air cleaners for the
construction industry has sprung from the heritage of the founder of Ermator air cleaners. After some years of silence this group of specialists decided to development professional air cleaners and formed Sila. (See feature on pages 32-33). But in almost every contractor’s store room in Scandinavia there is another brand, Pullman Ermator. The company had a large booth showing the majority
of its dust extractors, cyclones, air cleaners and their popular wet vacs and were also at the demonstration sites in the outside area. Also the company Nordic Air Cleaning System attended and showed their assortment of air cleaners. Another well-known participant at DEMCON shows has been IDAB- Industridiamant. The company has a long career in the concrete sawing and drilling

sector, but in the last decade focused more on construction fans and air cleaning, as well as mini conveyors for bringing out demolition debris in extremely confined places. This year Idab showed their construction fans called miniveyor air. The company BVM from Gothenburg are distributors for the German Heylo fans for construction sites. Heylo also has a solution for creating a vacuum in a sealed space in order to suck out dangerous dust. BVM also the new air filter FT1000. Trying to penetrate the Scandinavian demolition and concrete cutting industries is Nilfisk Advance with their line of vacs for dry and wet material. At DEMCON they showed their latest equipment. There was also dust extraction equipment from Husqvarna Construction Products, HTC Sweden and Scanmaskin.
Demolition robots - the core of the show Demolition robots are obvious ingredients at a Scandinavian show like DEMCON as Sweden is the home of the demolition robot. The oldest and biggest manufacturer in this field, Brokk, attended the show with a large booth showing a big portion of their latest machines, including the new Brokk 100 together with a line of attachments. Brokk’s main competitor Husqvarna showed their line of remotely controlled demolition robots together
with their latest concrete crushers. Also present was the Swedish distributor of Finnish Avant Tecno. The company manufactures compact and articulated dumpers and loaders, often used on demolition sites. The Avant can be equipped with a series of attachments and also hydraulic breakers and crushers. The company was expected to show a new remotely controlled demolition robot, following its acquisition a while back of the Finnish maker of demolition robots Finmac Demolition. But its launch has been delayed. A control box is needed to operate a demolition robot, wall saw or similar and two Swedish companies specialising in radio control equipment Datek and IRC, exhibited at the show for the first time. When cutting concrete it is often important to know the make up of the material beforehand. Ground penetrating radar specialist Mala Geoscience is able to perform this type of investigation. In Sweden the
PDi • Issue 4 • September - October 2012
concrete cutting industry is just beginning to realise the benefits this type of equipment can offer.
Dates set for 2014 PDi and its sister magazines Svensk Rental Tidning and Professionell Demolering had their own booth distributing over 1,500 magazines of each title during the show. DEMCON 2012 was a great success with many professionals from the relevant industries attending the show. The next DEMCON will be held on 4-5 September 2014 at the same venue, the InfraCity Business Centre north of Stockholm.

The Spec After the summer break our ‘Movers and Shakers’ column is back with a new story. This time we feature a company whose larger-than-life founder devised machinery and bred racehorses with equal success. He started his business in 1842 with six threshing machines bought on credit. Now 170 years on, his small enterprise has grown into one of the world’s largest manufacturers of construction equipment, employing thousands of people and selling its machines worldwide. His name was Jerome Increase Case. Text: Andrei Bushmarin, Foto: Case
Jerome Increase Case lived a classic American success story. He was born in 1819 in Williamstown, New York and one of seven children in a family of farmers. His circumstances most likely influenced his interest in agricultural machinery. As a boy, he read about the reaper machine that had just been invented and decided that it might be the way for him to go.
Started with treshers As a businessman, Case started out in 1840 by threshing neighbours’ crops with horse-powered devices. Two years later, he bought six hand-driven threshers on credit and travelled north. Along the way, he sold all but one unit, which he set about improving. When the upgraded model was fully ready, Case moved to Racine, Wisconsin, where he began production of threshers on an industrial scale at Racine Threshing Machine Works. Racine was chosen by virtue of providing access to water, a vital element of manufacturing. The 1860s was a break-through decade for Jerome Case. In 1869, he built his first portable steam engine to power wheat threshers. This invention led to a manifold increase in threshing capacity and signalled a new direction for Case. It was also in the 60s when Jerome Case adopted Old Abe, the eagle mascot of the 8th Wisconsin Volunteer Infantry Regiment, as the company’s logo. About ten years later, Case devised his first self-propelled traction engine, an innovation that revolutionised agriculture and road haulage. By the time Jerome Increase Case died in 1891, the company he had created was North America’s biggest manufacturer of steam engines.
Case backhoe loaders in 1957 The advent of oil engines, at the dawn of the 20th century, heralded a whole new era in machine building and necessitated a change in the company’s strategy. It was in 1895 when the Case Company delivered its first gasoline engine. Since then its focus started to shift towards construction and road-building machinery. By 1912 Case was able to offer a complete line of road-building equipment, including graders and steamrollers for compacting road surfaces. In 1927, Case ceased making steam engines altogether and changed the colour scheme of its machines from black-green-grey to the familiar orange-ruddy yellow. In 1929, Case designed its first crawler tractor and further reinforced its position in agricultural business. But it was not until 1957 when the company’s finest moment in the 20th century came. The introduction of the industry’s first fully integrated loader/ backhoe was a landmark event in Case’s history, comparable in significance with the development of steam engine one hundred years earlier. Case’s model 320, the Construction King, became synonymous with backhoe loaders in the United States. Case’s story in the second part of the century is one of mergers and takeovers. Its purchase of the American Tractor Corporation in 1957 led to the creation of integrated

backhoe loaders. Colt Garden Tractors Corporation was next to be taken over in 1964. Its tractors were equipped with the ‘Hy-Drive’ propulsion system that allowed for the use of various heavy-duty attachments. In 1972, Case bought the British tractor builder David Brown. It was also in the 70s when Case began to lean towards construction, while disposing of some of its assets in agriculture. But a truly watershed moment in Case’s recent history arrived at the end of the century when in November 1999 it merged with New Holland to become CNH Global. Fortunately, the Case brand survived the merger. In 2005, the 500,000th tractor loader/backhoe came off of Case’s production line. The accomplishments of Jerome Increase Case and Elton Long, the father of the legendary integrated loader/ backhoe, gained them an induction into the Association of Equipment Manufacturers’ ‘Construction Equipment Hall of Fame’. But Case is not only good at making tractors and loaders.
Case a perfect fit for German InduRec Construction work in densely populated, historical city centres has always been a sensitive issue. This is especially true when it comes to demolition projects, which are inevitably associated with noise and dust. And the exhaust emission regulations for construction machinery that get stricter every year represent a further challenge for contractors. Therefore, when faced with a task of dismantling the Sickinger Primary School in Mannheim city centre, Germany, the specialist contractor InduRec based in Weinheim, chose a new low-emission crawler excavator CX300C from Case. The 30t machine was fitted with a Lehnhoff quick coupler and 2.7t concrete sheers for the demolition work in the densely populated T4/T5 quarters, which have a square layout typical of Mannheim. The new CX300C meets all requirements of the EU stage 3B standard and Tier IV Interim regulation. The common rail turbo diesel boasts a CEGR system with triple exhaust gas recirculation and is equipped with a diesel particulate filter. Without the need for diesel additives, it therefore reaches the prescribed exhaust emission levels. An automatic selfcleaning function means continuous performance without loss of productivity. In operation, the new model generates minimum noise. Even in the directly adjacent residential areas, the CX300C can hardly be noticed, as it carries out its sorting work on the site’s former playground, aside from the occasional murmur of the pumps and crackling of the hydraulic shears. Interior soundproofing has now brought noise levels down to just 70dBA. “With various challenging dismantling and demolition projects under its belt in the Rhine-Main area, InduRec has made an excellent name for itself and ranks as the one of the region’s best companies in the field of selective dismantling, remediation, recycling and disposal,” says InduRec managing director Thomas Lück. “Our machine park currently has excavators of all sizes, from a compact machine with an operating weight

of 4.5t to a 65t long front demolition excavator, as well as many bulldozers and wheel loaders.“ InduRec deputy managing director and head of the company’s technical management team Markus Munique echoes his partner’s judgment. “With only 500 operating hours on the clock, the new machine obviously hasn’t been used for very long, but we can already say for certain that all data
on performance and consumption meet our expectations,” says Markus Munique. “The CX300C has been very reliable and economical so far. Since absolutely all of our machines are equipped with central lubrication systems, we generally do not have to dedicate a lot of resources to maintenance”. “We are very pleased with our new excavator,” says Thomas Lück. “The machine is an excellent and economical addition to our 30 t category and can even be used in city centres without a hitch thanks to the Tier 4 technology. So far, the machine has worked efficiently and 100% reliable. In this respect, the CX300C has passed its practical test with flying colours here at the school.”

NDTG passes skid steer test In the UK the National Demolition Training Group, the dedicated training arm of the National Federation of Demolition Contractors, has achieved a notable first by hosting the UK’s first demolitionspecific CPCS skid steer loader test. The first test coincides with the switch in training course designations from the previous A65 to the new D90 suite of competence cards. Key among these is the D92, Demolition Skid Steer in a Demolition Environment. The inaugural test took place at the Kettering Science Academy, a live Wilmott Dixon site with machines provided by AR Demolition. “On this kind of demolition test, we are looking for a different skill set to that of any other industry or sector. Candidates must be able to demonstrate a knowledge of the demolition environment and have a minimum of two years industry experience,” says NDTG assessor Duncan Rudall. “Operatives have to take a touch screen test first, undergo an hour long theory test, and then it’s onto the machine starting with a pre-start check of the machine and its surroundings. The test also includes driving the machine across a site, negotiating a variety of obstacles, and carrying out a range of demolition activities.” The first candidates to take the test were Richard Childs and David Smith from AR Demolition. Each successfully completed the test and will now carry a red CPCS D92 Demolition Skid Steer in a Demolition Environment card that is
valid for a period of two years. “The new test has been designed by demolition industry professionals to accurately mirror the very specific demands placed upon skid steer operators in this sector,” says NDTG training group manager Sophie Cox. “The way in which these machines are operated in demolition is unique to this industry and the new test reflects this. Skid steer loaders are used throughout the UK demolition industry to carry out a variety of tasks from top down demolition and internal strip out to rehandling and materials segregation. Our new test ensures that operators are prepared to meet these many and varied challenges.” For a video of this demolition test see: http://tinyurl.com/8z567jq

CSDA’s new concrete polishing class In the US the Concrete Sawing and Drilling Association will hold three training classes during the next World of Concrete trade show and exhibition on 5 to 7 February 2013 in Las Vegas. The first ever CSDA Concrete Polishing class headlines the training schedule, and starts one day after the first CSDA Operator Certification course to be held at the show. Completing the line-up is the CSDA Estimating class, which was introduced to the show’s Education Programme in 2012. “By participating in the CSDA Concrete Polishing class, contractors will learn how to eliminate the majority of risk factors associated with this discipline,” says class lead trainer Andy Bowman. “For the first time in the history of the sawing and drilling industry, a course has been created to educate people on a technique outside the core disciplines. Now, a contractor can gain important knowledge from CSDA that will help him or her produce a polished floor that exceeds customer expectations. The aim is to give participants a model for producing floors to a consistent high level of quality, regardless of the type of concrete.” The CSDA Core Drilling class is an Operator Certification course for experienced operators who want to gain the highest level of proficiency in this discipline. Content will be split between the classroom and the slab, with students spending time at the outdoor exhibit booths of CSDA member companies to perform practical exercises. “For the past two years, CSDA has produced classes aimed at new operators looking for training that gives them the fundamentals of sawing and drilling,” says CSDA executive director Patrick O’Brien. “In response to requests from members, we have adapted one of our Operator Certification classes for World of Concrete 2013. Now contractors can bring their best operators to Las Vegas and leave with an industry certification that will benefit their company.” The Estimating class will focus on the practice of estimating sawing and drilling jobs taught by industry experts with real-world experience.
Josef Plattner, owner and founder of the Plattner Corporation in Austria, died on 2 August 2012 when he was hit by lightning during a hunting trip. Josef was born on the 22 October 1953 in Oberhofen, a small Tyrolian town in Austria. He started his career in 1976 with Tyrolit where he learnt the diamond business during 17 years. After many years he was promoted to the Head of the service centres where he was responsible to build up the entire European service network. Being in daily contact with customers and confronted with their problems, Josef worked continuously on improving the existing equipment and designed new products for the company. Many patents were issued on the base of his ideas and inventions. During this time the idea of the wire saw was born. With his visionary thinking and his strive to build a diamond wire saw Josef finally founded his own company, the Plattner Corporation. Plattner Corporation is now one of the worldwide leading developers and manufacturers of wire saws and machinery used in the diamond consumable production. The operations started as a basic set up in his garage until the breakthrough came in 1996 when the partnership with the Hilti Corporation was founded. This solid and successful partnership still continues today. Plattner’s development and manufacturing plant is located in Schwaz, Austria, where new innovative products are crafted, also in co-development with Hilti. For Josef his employees were always very important. From the beginning he was taking care of them, building strong personal relationships with everyone in his company. Josef’s dream was to build a family business where all its members would participate. From the beginning he involved his sons and daughters into his business and passed along his knowhow and his visionary thinking. Today practically all of his family members are active in the business, each one in charge of a different department. Josef’s oldest son David Plattner, will take over his father’s succession as the general manager and will pursue Josef’s business together with the other family members. Plattner continues to be very solid and has established itself as a benchmark for wire sawing products. More than 1000 wire sawing systems have been sold worldwide. With his son’s succession Plattner will continue as a leading innovator and manufacturer in the wire sawing business. With our sincere condolences to all the family members. Thank you Josef!
