FRD-HYDRAULIC BREAKERS AND DEMOLITION ATTACHMENTS In cooperation with the Technical University of Tokyo, FRD could tremendously reduce the new breakers noise levels. 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.

Concrete cutting and fibre optics connecting the world Dear Readers What is happening to the world’s weather? Being a Swede and living in the northern hemisphere I have a reason to ask that question.

Association of Equipment Manufacturers. The two organizations discussed how their messaging has changed since the President signed MAP-21 into law on 6 July 2012. The Road Connection and AEM believe that although this is a step in the right direction for the construction industry, the 27 months of funding does not provide a permanent solution for contractors counting on these federally funded projects. “We are pretty excited about the passage of the bill,” says AEM president Dennis Slater. “However, at the same time, it’s a two year bill, a stop-gap measure, and a lot has to be done in the next two years to get ready for the next bill.” The Road Connection continues to take their message to the streets, urging the public to get informed on the new legislation, and to be cognizant that two years will be here quickly. The team will continue an aggressive letter-writing campaign to lawmakers in Washington, D.C., applauding them for their work on passing a highway bill, but urging them to think ahead so that the industry does not have to rely on short-term extensions once the bill expires.From Milwaukee, The Road Connection truck headed to La Crosse, Wisconsin and Riverside, Iowa before heading to the annual motorcycle rally in Sturgis, South Dakota on 4 August 2012.

The VDMA/CECE has published a short guideline What do your risk, when you use, buy or sell a non-compliant construction machine? It addresses all who use, buy or sell construction machines in the EU. Construction equipment made available on the EU market must comply with the relevant EU legislation and meet all valid safety and environmental requirements. Machinery which does not fulfill these requirements is non-compliant and is not allowed to be placed on the EU market. Dealers and construction companies which are caught when using, selling or buying non-compliant machines in the EU face serious problems. The guideline outlines the consequences in terms of reputation, business and liabilities that companies may have to face when acting illegally. The publication is available for download in English and German language at www.vdma.org/construction.

D-Drill claims it is the first company in its field to be handed a platinum award in the Construction Standards Certification Scheme and is one of only 1,400 in the UK construction industry to have it. The award highlights a commitment towards high standards and competency within all areas of the construction industry. More than 90% of D-Drill’s workforce is now registered under the scheme. Julie White, managing director of D-Drill, said the company’s commitment to high levels of training throughout the business was a major factor in the award. “Despite the economic climate, we have invested heavily in the training of our staff and our apprenticeship scheme is something I am very passionate about,” says White. “That has played a very significant role in us receiving the platinum award from CSCS. No other diamond drilling or sawing company has achieved such a high standard and that is testament to the team here.” The award is the latest in a long line of achievements for D-Drill, which is run by Julie White. Her commitment to the apprenticeship programme means more than 10% of the current workforce, including Julie, are apprentices and 45% have gone through the scheme at some point. Joel Vinsant with the Drilling and Sawing Association, hailed D-Drill as an example to others. “Receiving the CSCS awards is something we promote within our membership, particularly for an organisation of this size,” said Vinsant. “D-Drill is a shining example to the industry for its commitment to apprentices, training and industry best practice. Well done to Julie and her team for receiving the highest award from the construction skills certification scheme.”
ment 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.

Words from the IDE President
“Ongoing Evolution”
Demolition engineers are required to work within a legislative and regulatory landscape that is constantly shifting, continually changing. The ability to mirror, influence and steer those changes are a key part of the remit for any organisation hoping to have credibility among demolition professionals. I am, of course, fortunate to have around me at the IDE a dedicated and enthusiastic team that includes the national secretary, a vice president, and a council of management that give freely of their time and experience. And it is just as well. Since my last column, some significant changes have taken place within the Institute of Demolition Engineers and use this column to advise those changes: Our national necretary, Valerie Stroud, has completed the task of achieving the IDE’s official certificate of Professional Affiliate status in the Engineering Council. This gives greater
through this new route will be considered by the Membership Committee on 27 September 2012, with the first interview day proposed for October 2012. Overseas members of the IDE will now be able to choose the traditional examination route to membership or the Shared Support Route. This will mean that we will be able to quickly move entrant international members through to AMIDE level without having to arrange exams in different countries and different languages. It is proposed that the first Shared Support Route day for overseas members will be held in Italy in late 2012 or early 2013. IDE seminars have been arranged for 28 September 2012 in London and 22 February 2013 in Leeds and exhibitors have confirmed stands for both events with tickets on sale now from the website www.ide.org.uk And the changes within the IDE do not end there. On 16 November at the IDE’s annual general meeting at Lords Cricket Ground in London, I will hand over the presidency to my vice president, Steve Jack.

Equipment sector in an optimistic mood For 2012, European construction equipment manufacturers expect another modest increase in sales of 6% compared to last year. “The industry’s total turnover would then amount to EUR 25B,” said Committee for European Construction Equipment President Johann Sailer, during a press conference at Intermat. According to Sailer we are still far from the figures of top years of 2007/2008 where the European industry reached a record turnover of EUR 31bn, but the overall mood of European manufacturers is optimistic. A recent CECE survey showed that two thirds of the participating companies said they expected their company sales to grow further in the next six months, whereas only 10% expected a decrease. Incoming orders in the past months stayed steady around 5% above the same months of the previous year, with growth rates of orders from Europe a little lower than the ones from outside the EU. The growth in Europe comes mainly from north of the Alps, while the outlook for the Iberic peninsula remains gloomy. For the eastern part of the EU no fast growth is expected. However, Russia is expected to show stronger growth. Growth drivers from outside Europe are the BRIC countries, especially Brazil. Expectations for North America have been revised upwards during the past months. According to CECE’s survey the industry will create more temporary and permanent jobs in 2012. Sailer also said that the industry is facing many challenges, especially when it comes to EU regulations. CECE is worried about the high number of customers neglecting risks caused by cheap non-compliant machines. Brochures provide information on how to find out whether equipment is non-compliant and a new publication focuses on the liability risks of buying, using and selling non-compliant equipment. CECE and its members have also given a considerable amount of thought to carbon dioxide emissions. CECE is convinced that the solution for the industry should be a holistic approach, taking into account all the aspects of efficiency, instead of a one-size-fits-all solution. The right approach should include the optimal organisation of the worksite, the use of appropriate and efficient machines and the optimised use of machines by trained drivers. These, together with the use of alternative energy sources, are the appropriate tools for reducing carbon dixide. CECE is creating a toolbox from which manufacturers will be able to select the most appropriate solutions according to their products and challenges. Despite the problems facing the Eurozone and the challenges caused by the shifting of global markets outside Europe, CECE believes that there is a good long-term perspective for the European construction equipment industry. ‘Making it in Europe’ will be the title and focal point of the next CECE congress, scheduled in Berlin on 25 and 26 October 2012.

Hilti maintains growth momentum The Hilti Group maintained its growth momentum from 2011 over the first four months of 2012. Sales rose 8% in local currencies compared to the same period one year earlier. The growth in sales in local currencies is reduced when converted to Swiss francs of CHF 1315M, 3% higher than in the previous year. All sales regions contributed to the increase, although significant growth was seen in the growth markets in which the Hilti Group has developed additional resources in recent years. Latin America continues to be the strongest market, with sales advancing 39% in local currencies. The regions of Asia/Pacific and Eastern Europe/Middle East/ Africa both achieved 12% growth. North America also grew by 14%. In spite of the negative developments in some Southern European countries the Hilti Group achieved an overall growth level in Europe of 3.5%. “The company’s organic growth continued over the first four months of 2012 while the measures we have instituted to increase our profitability are beginning to show initial positive effects,” said Hilti chief executive officer Bo Risberg. Based on the current market outlook the Hilti Group continues to expect single-digit growth in local currencies in 2012.

Ekokem expands The Finnish waste treatment company Ekokem has acquired all shares in the Swedish environmental management company SAKAB from the international energy company E.ON. In 2011 the turnover of SAKAB was EUR51M and the company has 150 employees. “This merger is in line with Ekokem´s strategy. Ekokem and SAKAB’s competencies in customer service and industrial solutions ideally complement each other. This provides both companies with greater opportunities to meet environmental sector challenges in the improvement of material and energy efficiency, as well as removing hazardous waste from the material cycle,” says Ekokem chief executive officer Timo Piekkari. Activities at SAKAB are divided into three key areas. There are two lines for incineration, one line for soil remediation and one line for inorganic waste. SAKAB´s main treatment facility, set up in 1983, is outside Kumla. Over the years the facility has been expanded and improved, both in terms of capacity and to meet new requirements. SAKAB also has about ten sales offices and transfer stations in Sweden. Ekokem was established in 1979, the shareholders being the Finnish state, municipalities and a large number of industrial companies. The treatment of hazardous waste commenced in 1984 in Riihimäki. Today Ekokem seeks to save natural resources
by improving its customers’ material and energy efficiency, and by providing recycling, recovery and final disposal solutions, as well as soil remediation and environmental construction services. Ekokem has 18 treatment centres, transfer stations and sales offices all over Finland and also international customers.

Bobcat’s 25th Anniversary Limited Edition Excavator Marking the 25th anniversary of the Bobcat compact excavator range, a new Limited Edition version of the Bobcat E16 1.6t compact excavator with unique styling has been launched. The Limited Edition model provides an attractive complement to new enhanced versions of both the E16 and the 1.4 t E14 compact excavators, which have also been launched by Bobcat. Compared to the existing models, the enhanced E14 and E16 excavators feature new exterior styling. Inside the cab, the most important improvements are the new ergonomic travel levers and pedals that have proved very successful on the larger E26 excavator model. The E14, equipped with a heated cab, has an operating weight of 1.5t and offers a maximum digging depth of 2.3m. The E16 offers a choice of a standard and a long dipper stick. Equipped with heated cab, the E16 excavator with standard dipper stick has an operating weight of 1744 kg and offers a maximum digging depth of 2422 mm. Equipped with the long dipper stick, the E16 has a maximum digging depth of 2602 mm. Both models have the cylinder-over-boom design. Since the cylinder is mounted on top of the boom, it is protected when working in tight spaces or with attachments. The auxiliary hydraulic lines and workgroup hoses are mounted inside the boom and arm for protection and enhanced visibility. Attachments, which include a range of different sized digging and trenching buckets, grading buckets, hydraulic breakers, augers and the hydraulic clamp, can be easily mounted. Both the E14 and E16 are powered by the 3-cylinder 9.9kW Kubota D722 engine.
Kolberg-Pioneer’s Colombian Visitors In the US Kolberg-Pioneer recently welcomed customers from two Colombian companies to its factory. The customers, who included Jose Alebrto Sanchez and Fredy Sanchez of Transportes Sanchez, and Diego Ibarbo and Oscar Salamanca from Mincivil, were visiting the factory to purchase equipment and receive parts for KPI-JCI equipment. They traveled with Stiven Angle of Rylsa, a KPI-JCI and Astec Mobile Screens dealer, and Fernando Marroquin of Astec Aggregate & Mining Group. KolbergPioneer international sales coordinator Bruce Viau said that the company has experienced steady growth in the Colombian aggregate processing market since 1992, when it held a seminar for contractors, government employees and dealer personnel on then current aggregate processing and washing practices in Bogota. “Since that time, KPI-JCI and Astec Mobile Screens, as well as the rest of the Astec Industries companies, has expanded its dealer organization and market penetration with multimillion dollars of goods sold to our Colombian customers,” said Viau. With the passage of the US-Colombia Trade Promotion Agreement on 15 May 2012, which makes more than 80% of US industrial goods exports to Colombia duty-free, Viau expects an even stronger relationship between KPI-JCI and Astec Mobile Screens and its Colombian customers. “As Colombia has become a safer destination for business travel, the pace of construction has stepped up and infrastructure is now being built with great emphasis on road construction,” said Viau. “The new trade promotion agreement levels the competitive field for our goods, allowing us to compete with our high-quality, American goods. It’s also good for users in Colombia, because it is more financially feasible to seek out equipment from American manufacturers.”

Atlas Copco launches MB Essential breaker range Atlas Copco Construction Tools has introduced a new product variant of medium hydraulic breakers, the MB Essential range. The new models are focussed on the essential high performance, low weight, and essential features for efficient work. The idea is simple. Breaker features are reduced to the essential to manage their daily targets. The new range comes without ContiLube II and the noise protection kit. Due to the design and configuration, MB Essential breakers
are powerful tools that do nothing else but their job. Regular service and maintenance can be easily done on site. The power to weight ratio and the efficiency of Atlas Copco´s latest generation of medium hydraulic breakers have been significantly increased, compared to their predecessors. Due to lower weight and higher efficiency, less hydraulic input power is required from the carrier, while maintaining maximum impact performance.
This allows smaller carriers to be used, which results in lower investment cost for the carrier. Atlas Copco Essential breakers are designed to get tough and hard jobs done in MB 750 E

New Cat breakers Caterpillar is expanding the E Series Hammer line with the new H75Es and H95Es, designed for backhoe loaders and small excavators. E Series hammers build on Cat’s proven D Series features, such as automatic shutoff, which instantly stops the hammer when the tool breaks through material. The system increases hammer reliability and durability by eliminating the high internal stresses created by blank firing. Sound suppression is standard for environmental protection and improved operator comfort. Cat hammers deliver high blow energy and frequency, which means more breaking power on the job. The H75Es delivers 1,356J (1,000 lb.ft) of energy at 840 to 1,650 blows per minute. The H95Es delivers 2,034J (1,500 lb.ft) of energy at 700 to 1,260 blows per minute. The H75E and H95E hammers feature a gas-fired system that maintains constant power between service intervals. A sleek, curved front and back profile eliminate stress points and transfer forces to the bottom of the hammer. Additionally, the H75Es and H95Es are sized and shaped to curl and tuck under a Cat backhoe loader boom for easy transport on the machine without boom damage or interference with traffic. Cat hammer settings are preprogrammed in Cat excavator tool control systems for easy set up. The oil flow and pressure are fully adjustable in the tool control program. Actual hammer working hours can be recorded for routine maintenance purposes. Easy serviceability and rebuild features help keep life cycle costs low. The H75Es and H95Es hammers are matched to the full line of Cat backhoe loaders, and to Cat 307, 308, 311, and 312 hydraulic excavators.

and metal cutting. The company has also added the sorting grapple for sorting and separating materials for recycling and recovery and can be fitted to 1.2t to 14t machines.
White pads from Ashine According to Chinese manufacturer Ashine their new white pads have an amazing power and without staining the floor they are polishing. Two years ago a Scandinavian contractor was looking for stain free polishing pads for use on white terrazzo floors. The company tested many top brands’ pads, but none met the demand, including Ashine’s neutral pads. Ashine diamond tools president Richard Deng valued the new requirement and the company’s research and development team carried out a lot of experiments before eventually succeeding. After testing the new Ashine white pads, the contractor said that they were the most efficient and unique solution for white terrazzo and that no other brand of pads had better cutting power than Ashine’s white pads. Another contractor also commented, after polishing an extremely hard new terrazzo floor with Ashine white pads that compared to other brands the Ashine white pads gave the best surface uniformity and depth of colour. As a pioneer in the field of surface preparation and concrete flooring, Ashine focuses on product development and offers complete solutions for different requirements.

Neuenhauser provides screening solution for damp materials The UK’s sole distributer of Neuenhauser equipment, Riverside Machinery, is able to offer a screening solution that processes damp material thanks to the German manufacturer’s range of star screens. These machines utilise a deck of rotating stars to screen a variety of material including green waste, trommel fines, soils and fly ash. Unlike some conventional screening systems the star screen is not subject to blockages or reduced output when processing wet material, therefore remaining effective regardless of the weather. The Neuenhauser Star screen is available as a road-going trailer unit, independently mobile tracked unit, or fixed unit and can screen high volumes of material to sizes between
10mm and 80mm. Commenting on the Neuenhauser Starsceeen’s capability, said ‘The past few months of heavy rainfall have caused a backlog of material for many material processors whose current equipment is unable to screen damp or wet material,” said Riverside Machinery sales director John O’Neill. “As a result, companies that are experiencing high demand for their end products or have restrictions on storage space may benefit from the Neuenhauser Starsceeen.” Riverside Machinery is able to offer several tracked and wheeled Star Screens for hire and the full range of Neuenhauser machinery is also available for demonstration.
Husqvarna crusher renovates tax office The Swedish Tax Agency office in Solna in Stockholm, Sweden is being demolished by contractor Pentka Demolition. “We are removing the floors and beams from the courtyard to open it up completely. Excess vibration is not permitted during the demolition work as the Swedish Tax Agency office houses its data centres under the building. This was why we decided to use Husqvarna’s robotic crusher for the first time,” says Pentka Demolition representative Pentti Karhunen. The district of Nöten in Solna, where the Swedish Tax Agency office is a tenant, is undergoing extensive renovation and moderni-
sation. The Swedish Tax Agency office will rent 44,000m2 in the new modern and environmentally friendly premises. Pentti Karhunen and his son Toni Karhunen perform the heavy demolition
Bobcats in Löhrhof centre demolition
As subcontractor to GL-Abbruch, InMotion Construction and Trading Services of Düsseldorf has been responsible for the interior gutting and asbestos removal work involved in the demolition of the former Löhrhof Centre in Recklinghausen in Germany. InMotion has chosen Bobcat compact loaders and excavators to carry out this work inside the building. The Löhrhof Centre was built in 1975 and is one of the oldest shopping centres in Germany. It closed down in February 2012 to make room for the new Recklinghausen Arcaden Mall occupying a total retail space of 27,700m2. The opening is planned for Spring 2014. However, before construction can begin, the old Löhrhof Center has to be demolished. This involves demolition of 167,000m2 of enclosed space, requiring the removal of some 70,000t of concrete, more than 30,000 lamps, 18,750m2 of floor covering and 10,000m2 of dry walling. “I have been working for 20 years with machines from Bobcat. Their robustness and powerful performance make them ideal for use on demolition sites,” says InMotion Director, Zijad Delibasic, who has specified Bobcat compact machines to complete the gutting work. He has a Bobcat S650 compact loader and an E16 compact excavator on
20
the job at Recklinghäusen site. The S650 is being put to work outside and inside the building where it is ideal for loading debris into on-site containers. The poly-fill tyres on the S650 have proved to be particularly useful for work on demolition jobs. “During demolition work, tyres are exposed to the toughest conditions due to sharp stones, iron and glass, so we advised InMotion during the purchase consultations to take the poly-fill tyres,” says Bobcat branch office manager in Mülheim Rainer Pieper. “Even if they are pierced by a piece of reinforcing steel, they remain fully functional and can continue to work. At the same time, they also offer much greater driving comfort than conventional pneumatic tyres.”
PDi • Issue 3 • July - August 2012
In addition to the normal construction and industrial buckets, InMotion also uses a universal bucket equipped with a clamp. For the transport of metal and steel scrap or wood, especially, the grippers make the work much easier by holding the material in the bucket while the loader is being driven. A pallet fork attachment is also available to lift standard pallets and other objects such as a 2.5t emergency generator. The compact loader is also used on the site with a sweeper attachment to clean the roads. The Bobcat E16 compact excavator is being used chiefly inside the building. Under these conditions, the adjustable undercarriage can open up to its full width. With the undercarriage retracted, the E16 only needs a 1m wide and 2.18m high opening to move from one room to the next. Extended to its full width of 1.36m, the undercarriage offers unmatched stability. Equipped with a backhoe bucket and adjustable stabilizer and dozer blades, it is suited to demolition clearance work. A hydraulic hammer attachment is also proving very useful in the gutting work at the Löhrhof Center. Servicing of the machines is provided by Bobcat Mülheim, one of 16 branches Bobcat Bensheim has in Germany.

of the building, in cooperation with Contender Demolering, which is drilling all the holes. “The challenge was how to perform the demolition without having to break up the concrete, in order to reduce the amount of vibrations. Vibration meters are fitted around the entire building to keep us updated on what is going on. We also have to take into consideration the office blocks around the building,” says Pentti Karhunen. Remotely controlled demolition robots are becoming increasingly popular in the demolition industry. For the job in Solna, Pentka Demolition is using Husqvarna’s DXR 250 demolition robot with the DCR 300 robotic crusher. “We needed a slightly bigger machine for the job and a strong robotic crusher, which is why we chose Husqvarna. This crusher presses 45t and is the most powerful in its class, even if the machine is rather light in weight, making it very user friendly. The concrete is reinforced and thereby extra hard so the robotic crusher will be put to good use, and it does help us to get the job done both faster and smoother,” says Pentti Karhunen. Toni Karhunen has configured Pentka Demolition’s own settings for the remote control. These adjust the speed and indicate pressure and temperature levels at a distance. “It’s a big building and it’s great that Pentti is so happy with the machine. He is a skilled operator,” says Husqvarna representative Ola de Besche. The move into the new premises is scheduled for October 2014. The main contractor for the assignment is Veidekke Entreprenad, who was awarded the contract by Fabege.

HTC Sweden introduces a new innovative dust extractor
Both Sila air cleaners have coarse air filters of single use type that have been developed to ensure that the filter is not saturated too quickly. The H13 high efficiency particulate air filter comes fitted with a contact guard. Both machines also have a filter guard, which indicates when the filters need to be cleaned or replaced. They come fitted with electric sockets so that handheld power tools can be connected. They can also be fitted with an optional evacuation hose, which can be fitted on either the clean airside or the filter side. “However, the most important feature of our air cleaners is safety,” says Sila sales and marketing manager Andreas Lundin. “Therefore, we have no eccentric locks on our products, a detail that greatly increases user safety. It makes no difference how effective a HEPA H13 filter is if it is placed in a structure that has weaknesses. Eccentric locks have a tendency to slide up during transport, or break if they are knocked. Therefore we fit our filters by screwing and minimize the risk of quartz and asbestos particles contaminating the clean side.” Sila’s air cleaners are also equipped with an accessory called ‘saneringsram’, meaning clean-up frame. This is a simple but ingenious and patented design that eliminates the time consuming taping process in the creation of temporary dust barriers. The air cleaner is placed on the outside of the wrapping. The clean-up frame is then placed on top of plastic against the air cleaner with built-in magnets. The plastic inside the frame is cut away to leave a perfect hole for the air cleaner.
HTC Sweden is well known as a developer and manufacturer of machines for professional floor systems. The company also produces a range of dust extractors and has recently introduced the new remotely controlled HTC 80 iD. The manufacturer states that the new HTC 80 iD improves efficiency up to 15% compared to a traditional dust extractor. The HTC 80 iD is equipped with a high performance integrated preseparator that removes up to 95% of the dust and increase filter lifetime. The HTC 80 iD can be used in various ways depending on your setup. For maximum efficiency and output, a remotely controlled grinder from HTC is recommended. The unique bypass valve leads to continuous operation, something that has been impossible with conventional dust extractors. However, a traditional grinder without remote control still benefits greatly from the double Longopac. This is a bag system that gives a simple and dust free dirt disposal. The high performance integrated pre-separator has the ability to use the optional remote control to turn the dust extractor on and off from a distance. Like all HTC’s dust extractors, the HTC 80 iD is HEPA 13 classified, which also makes it suitable for asbestos removal.

ber the second edition of the popular Nordic demolition exhibition DEMCON will take place at the InfraCity Business Centre north of Stockholm.
DEMCON is the revival of the show Demotech that was staged in Stockholm during the end of the 1990s. When the show was organised in 2010, after a 10 year recess, it was very welcomed by the industry. DEMCON is known to be a very focused show covering sectors like demolition, recycling, concrete sawing and drilling, diamond tools, concrete floor grinding and polishing, hydrodemolition, dust and concrete slurry extraction, cleaning of hazardous waste and soil treatment.
Only for industry professionals The show only invites industry professionals, which means that the number of visitors is rather moderate, but the quality of the visitors is very high. DEMCON is also known as a show with an extensive amount of business done during the exhibition. The DEMCON exhibition arena is located in the
InfraCity Business Centre in the suburb of Upplands Väsby, about 30 km north of Stockholm City. It is right next to the motorway E4 between Stockholm City and the international airport Arlanda. From the fair to the airport it is only a 10 minutes taxi ride. In direct connection to the exhibition hall is the Scandic InfraCity Hotel, where most of the exhibitors stay, but there are other hotels nearby. DEMCON attracts visitors from the around the world as there are very few similar exhibitions. The main audience comes from Sweden and the other Nordic countries, as well as the Baltic States and other countries in northern Europe. The majority of suppliers to the industries represented in the Nordic region at DEMCON will be exhibiting their products.
The Swedish Demolition Awards In addition to the exhibition, there will be a lot of other activities at and around DEMCON. On Thursday 6 September in the evening the DEMCON Party will take place in the Scandic InfraCity Ballroom. During the party the first Swedish Demolition Awards will be inaugurated and nine different awards will be handed out covering the following: Demolition Contractor of the Year Concrete Cutting Contractor of the Year Demolition Project of the Year Concrete Cutting Project of the Year The Safety and Working Environment Prize The Recycling and Environment Prize Manufacturer and Supplier of the Year The Innovation Award of the Year The Honorary Award
The nomination process has ended and a special jury is now assessing the extensive nominations. The winner of the Concrete Cutting Project of the Year will automatically qualify as a nominee for the International Association of Concrete Drillers and Sawers’ Diamond Award, which will be given at the Bauma show in 2013.
Competitions, meetings and seminars Another event that will run throughout the show in the outdoor area is the Nordic final of the Tyrolit Cutting Pro Competition. This international concrete cutting competition is now well established and the final between

PROFESSORS OF DIAMOND TOOLING Germany-based Dr. Schulze Diamond Solutions does not wear the title Doctor to pump up its self-importance. It means what it says. When Reiner Schulze founded his company more than 25 years ago he was a PhD in mechanical engineering. Reiner’s deep knowledge of the subject, perseverance and unrelenting commitment to quality has let him turn Dr. Schulze into a universally recognised brand in the diamond tooling industry. PDi’s Andrei Bushmarin reports.
Above a diamond bead for steel cutting wire – one of the company’s latest innovations. Below personnel at Moeckern plant.
Of course, Dr. Schulze as a company does not hinge on just one man. Manufacturing business is a team game, but it makes sense to begin Dr. Schulze’s story by focusing on its founder, whose knowledge and skills are still vital to the company’s well-being.
Self-made man The description self-made fits Reiner Schulze to a tee. Impetuous, creative and hard working, he belongs to that rare breed of self-starters who do things their way. People like him do not fit easily into existing schemes, but tend to carve their own niche instead. And the end result of their endeavours is usually pretty amazing. Reiner Schulze has built his international business from scratch, from a small workshop in the little hamlet of Wilnsdorf. It was there that the alumnus of the Hannover University, renowned for its research in stone and concrete cutting, began experimenting with diamond and metal powders trying to find a perfect recipe for his diamond tools. The choice of business was predetermined by Reiner’s major at the university and his PhD thesis ‘Cutting of hard minerals’, which he defended in 1981. The experimenting in the workshop went on for a few years and resulted in the company Dr. Schulze GmbH being established in 1986.
Enjoying the heyday For diamond toolmakers, the 80s and 90s were a glorious time. The demand soared high above the supply, so did the prices. Diamond tools were a rare commodity and, despite the exorbitant price tag, manufacturers had customers lined up for months ahead. With competition scarce on the ground, Dr. Schulze was able to ride the wave of staggering demand almost untroubled. Despite the fact that the manufacturer prioritised the construction industry from the start, it did produce, and still does, diamond tools for stone cutting as well.
Expansions and takeovers The company grew rapidly during the last two decades of the previous century. By the end of the 80s, production

capacities of Dr. Schulze’s plant in Wilnsdorf were no longer enough to satisfy customers’ ever-growing appetite, so a new factory was built in Lüneburg in 1989. The new facility was equipped with automated production lines and it was there that Dr. Schulze began to manufacture large volumes of diamond segments, along with laser-welded blades and core bits. A part of the factory was turned into a service shop where customers based in Northern Germany could get their tools and machines repaired. In 1991, the company expanded its manufacturing base again by acquiring a facility near Magdeburg where it arranged production of steel core bodies and ring segments for core bits. In 2002, Dr. Schulze reinforced its position in the hardware segment by taking over Meissner, a German manufacturer of sawing and drilling equipment. Dr. Schulze began to experiment in machinery as early as 1994, but it was not until the takeover that the company was able to offer a full range of cutting and drilling equipment.
Enter the Levins Strategically, Dr. Schulze has always focused on the CIS and Eastern European countries, which, after the collapse of the Eastern Bloc, turned into a huge, and potentially very lucrative market. But making full use of that potential took two talented and driven Russians. It was by a twist of fate that Reiner Schulze met Sergey Levin and his son Alexey in the late 80s. As it often happens in life, the Moscowbased family had never dealt with diamond tooling before, but they were willing to give it a try. The Russian branch was established in 1992, and Sergey and Alexey, who was in his teens at the time, got down to work. Despite their inexperience, the business took off like a rocket, and Russia has remained one of Dr. Schulze’s best markets ever since.
Child of globalisation – a modern type of leader The career of Alexey Levin is both remarkable and yet somehow typical in our time of globalisation. Moscowborn and raised, he graduated from the Gubkin State University of Oil and Gas in Russia and got his own PhD in material science from the University of Siegen in Germany. No wonder he half-jokingly calls himself ‘a child of

globalization’. Soon after he started out at Dr. Schulze on a part-time basis, his enthusiasm and work capacity got noticed by Reiner Schulze who took the youngster under his wing. Having got his doctorate in 2005, Alexey joined the company full time, first as Reiner’s assistant, and then in 2007, he replaced the founder as the company’s managing director. Being appointed to run a manufacturing business of 80 staff at the age of 28 by a man as demanding as Reiner Schulze was no mean feat and a challenge to which Alexey rose admirably.
Baptism of fire His managerial abilities were put to a harsh test when the global recession struck just a year after he had taken the helm. The period from late 2008 to early 2010 was undoubtedly the industry’s darkest hour in its recent history. Companies went under by the score, while those that survived had lost 30% to 50% of their business. Dr. Schulze emerged from the turmoil largely unscathed thanks to the carefully planned export strategy. By late 2008, the manufacturer supplied its products into around 40 countries, and fortunately not all of them suffered the fate of Spain. The economies of Poland, the Czech Republic and a number of Middle East states kept growing during the meltdown, and Dr. Schulze used its strong position in those markets to offset the damage. Dr. Schulze’s subsidiary in Poland did a particularly good job of helping the company to get through the tough times. This well-balanced export policy and constant expansion of the dealer network allowed Dr. Schulze to cap its losses at the 10% level in 2009 and an incredible result for the industry’s worst year ever.
New plant for new products At the height of the crisis, Dr. Schulze did not just curtail
production, but also invested in the construction of its biggest plant so far. It was a long-term decision aimed at getting an edge over competition once the economy would have bottomed out. This new 5,000m2 facility in Moeckern, a small location near Berlin, is to become Dr. Schulze’s flagship plant. The company plans to move most of its production units to Moeckern. The location was chosen by virtue of providing direct access to the main motorways that connect Eastern and Western Europe. At the moment there are 20 employees at the plant under the technical supervision of Reiner Richter, the research and development production manager. He oversees the development of a range of new products, among them is diamond wire for steel cutting applications. The production technology is top secret, but according to the company, the new wire has shown amazing performances during testing.

Fast, flexible and dealer friendly Twenty eight years on, Dr. Schulze Diamond Solutions remains a tight-knit team of professionals that focus on quality, prompt technical assistance and constant product development. Since export accounts for around 70% of the company’s turnover, much emphasis is placed on supporting and expanding the dealer network. In each market, the German manufacturer aims to build long-term exclusive partnerships with just one dealer. In return, Dr. Schulze offers its local representatives information and technical assistance on a constant basis. Today, the company operates through dealers and distributors in more than 40 countries, the strongest markets being Eastern Europe, Russia, Kazakhstan, Belorussia, the Netherlands, Switzerland and Finland. Apart from Europe, the company has customers as far as Australia, Middle East, Asia and Africa. Being a mid-size player, Dr. Schulze takes pride in its lead times

and flexibility. On top of its own products, a considerable share of the company’s output is supplied to the international market under various private labels. Having been in the business for over a quarter of a century now, Dr. Schulze has earned the right to be called ‘the professors of diamond tooling’ and, as true academics, they know that there will always be new things to discover and that research must go on.

Mini and compact excavators have never had much difficulty attracting the interest of contractors. After all, there are always applications where bigger is not necessarily better. PDi’s Jim Parsons takes a closer look at what’s new in this field. With many of the world’s construction markets still withered by the global financial crisis, it may well be time to reclassify this “niche” category of equipment as being very much mainstream. Though expansive “greenfield” initiatives can still be found, the combination of constrained government budgets and still-hesitant capital markets means that the recovery of construction will likely be dominated for some time by renovations, repairs, and similarly smaller projects on smaller, more challenging sites.
Not only the size matters As such, contractors and equipment rental firms need to make sure their arsenals are up-to-date with units that not only possess the size (or lack thereof ) to get the job done, but also perform reliably, provide for easy to operation and maintenance, and meet increasingly stringent regulations for air quality, ergonomics, and

Mini and Compact Excavators Make a Little Go A Long Way fuel efficiency. These features and more can be found in each of the products contributed by the world’s leading equipment manufacturers to this report. In many respects, it’s simply business as usual—good products made better through innovation and new technology. Yet these mini and compact excavators also reflect the fact that the world, at least figuratively, is a smaller place than just a few years ago—smaller economies, smaller projects, smaller margins for error. And, it’s a world where mini and compact excavators are poised to make a big contribution to any contractor’s strategy for success…and survival.
Kubota’s U55 tight tail swing compact excavator provides power in confined work spaces The largest model in Kubota’s U Series of compact excavators, the U55 five ton tight tail swing compact excavator is designed to provide outstanding power while working in tight job sites, where lifting capacity over the front is important. With a medium-length arm that enhances arm crowd force, a wide doorway, and plenty of operator space, the U55 replaces Kubota’s popular KX161-3 compact excavator. “Contractors find the tight tail swing on the U55 to be the machine’s most attractive feature because it allows the operator to complete jobs quickly in confined work spaces,” says Keith Rohrbacker, Kubota product manager. “In addition, float is now intrinsic to all U55 standard and angle blades, increasing backfilling productivity and simplifying finish work.” With only 63.5mm (2.5 in) of tail swing overhang, the U55 is powerful, yet compact enough to operate efficiently and carefully in narrow work spaces; minimising the chance of harm to panels and reducing long-term operating costs. A 35.5kW (47.6 hp) direct-injection Kubota diesel engine features single-side servicing, and includes an automatic idle feature that conserves fuel and reduces noise. A load-sensing hydraulic system employs a combination of closed and open center controls to ensure strong digging forces and minimise “slowdown” during
travel when using attachments. The advanced loadsensing system provides optimum oil flow to each cylinder for smooth multi-functional operation and enhanced fuel economy. Auto-downshift travel motors smooth transitions through turns, and the optional hydraulic angle blade improves backfilling efficiency. Float is standard equipment on all blades, combining with high traction force to speed the operator on to the next job. These blades include a reversible bolt-on cutting edge to reduce operating costs. Two auxiliary hydraulics ports are also now available, expanding attachment versatility. The operator may exchange hydraulic attachments and leave the thumb connected at all times, speeding attachment changes. With dual-element air cleaner and sideopening bonnets for convenient access to the service points, the U55 is easy to maintain. Light, simple wrist movements are all that are required to operate the fully hydraulic pilot control system. The U55’s auxiliary hydraulics system is equipped with attachment flow pre-sets from the control panel and thumb-ready sticks to speed attachment installation and changes. The U55 uses X-frame construction for high strength and excellent stability. The frame’s angle design has enlarged cleanout ports for easier clean-

ing, which saves valuable time. The number of dualflanged lower track rollers has been increased as well to reduce vibration for a smoother ride and longer track life. Kubota flawlessly matched the three-pump load sensing system with the auto-downshift travel motors, resulting in the ability to make quick, smooth turns. The sleek design of the Kubota U55 includes several features for operator comfort. Entry and exit is easy with wide doors and a large operator space, plus optimal legroom. This model offers a comfortable highback suspension seat, while the arm rests can be adjusted to a comfortable position for the operator. Full pilot and ergonomically placed controls optimise the operator’s well-being and reduce fatigue. A conveniently located digital display panel provides vital information at a glance, even notifying the operator when maintenance is due to avoid breakdowns and cut maintenance costs. Wide-ranging safety attributes include swivel and travel negative brake systems that hold the machine in place on slopes. These systems simplify transportation and provide almost infinite positioning to improve load spacing. To help ensure optimum operator safety on job sites, all canopy and cab
models feature roll over and falling object protection system (ROPS / FOPS) certification. Kubota’s own anti-theft system, included as standard equipment, is designed to keep equipment from getting stolen and to help eliminate the expense of theft recovery.
New JCB 8018CTS sets benchmark for power and productivity Launched at Intermat 2012, JCB’s new 801 1.5t (1.6 ton) mini excavator offer customers more than 30 improvements for reduced cost of ownership, greater productivity, safety, and comfort. A new style fabricated box style boom gives the 8018CTS a rugged and robust appearance, while its slim construction provides excellent visibility down the trench. All dig end hoses are routed through the inside of the boom, offering excellent protection when digging narrow trenches. Mounting the boom cylinder atop of the boom instead of underneath provides greater protection to the cylinder, and lowering the cost of ownership. Dig depth has been increased by an impressive 11% (244mm/9.6 in), which allows excavations up to 2.48 m (8.1 ft). Performance is further enhanced by adding 52mm (2
in) to the dump height, giving a load over height of 2.68m (8.8 ft). Reach has been increased by 138mm (5.4 in), taking ground level reach to 4.16m (13.6 ft). All this has been accomplished even though the front swing radius has been reduced by 92mm (3.6 in) to make the machine even more compact when working in confined spaces. In addition, the bucket now cleans up to the dozer when a Quickhitch is fitted, aiding site clearance operations. The 8018CTS is powered by a14.2kW (19 hp) Perkins engine. With more customers using 1.5t (1.6 ton) minis for lifting as well as excavating, JCB has improved load-holding capacity by a massive 52%. This has been achieved by increasing the boom ram diameter from 55mm to 65mm (2.1 in to 2.6 in) to create greater lift force, moving the kingpost closer to the centre of the machine and lowering the center of gravity, and use of a premium hydraulic valve system. For improved operator comfort, the 8018CTS features an expanding undercarriage with short pitch tracks to reduce the transmission of noise and vibration while tracking across work sites. Tracking speed is now manually controlled via a push-button switch conveniently mounted on the dozer lever, giving ultimate control of travel speed during dozing and trailer loading operations. A revised profile encourages material roll, enhancing dozing and grading performance. Hinged dozer extensions can be effortlessly deployed for work, or stowed for travel simply by the removal or installation of a single locking pin. The blade is 160mm (6.3 in) further forward, giving improved stability over the front of the machine while also giving the operator better visibility to either edge of the blade. The cab on JCB mini excavators is one of the largest on the market, with a wide door opening for safe entry and exit. The cab floor is flat and easy to clean, while flat glass has been maintained throughout for low-cost replacement. To further reduce the cost of ownership, a lower steel door panel is now standard on the machine to eliminate the need to replace damaged glass. Inside the cab, pedals have been relocated so that the boom swing is now on the right-hand side and the auxiliary on the left. The tracking levers have also been refined to make tracking more precise, especially at slower speeds. To maintain best-in-class service access, JCB’s tilting cab elevates the cab or canopy to give unrivalled access to the engine, valve block, slew motor, and rotary joint. Quick-release track levers and foot pedals allow a trained technician to quickly lift the cab in any environment. The tilt angle of the cab has been improved by 17%, allowing even better service access to superstructure components. A solid-cast counterweight ensures that the rear of the new 8018CTS is the strongest and most protected in the industry, able to withstand the harshest of impacts and operating environments especially when combined with a 3mm (.12 in) steel bonnet, the toughest in its class. The hinged bonnet, with gas-strut assisted opening and closing, is even stronger because the plastic air intake grille has been replaced with a perforated steel grille. The bonnet has also been improved for better durability and external noise reduction. And to lower the cost of ownership for the customer JCB has also introduced steel bushes in the kingpost, dipper nose and bucket for increased durability.
JCB’s new 8026 mini is a strong and durable performer Sharing the Intermat 2012 spotlight for JCB was 2.7t (3 ton) 8026CTS conventional tail swing excavator.

PDi • Issue 3 • July - August 2012
The 8026 is even more efficient than its predecessor 8025 model, thanks to the lower power rating of the three-cylinder 18kW (24 hp) Perkins engine that delivers an 8% efficiency gain, driving a Nachi variable displacement hydraulic pump. A slew turret that is now 35mm (1.4 in) lower provides a lower center of gravity, which, combined with the 1.22m (4 ft) tail swing around the new black counterweight, gives the 8026CTS outstanding lift capacity and excellent stability. That results in better productivity, versatility, and operator confidence. A new top roller, used in place of a metal skid plate, increases the durability of the new short pitch tracks, which reduce noise and vibration. The open turret design and angled track legs allow spoil to fall more easily from the undercarriage, and helps prevent the buildup of material within the track frame. This makes the 8026 far easier to clean and maintain. Auto kick-down track motors improve travel speed by 11% to 5kph (3 mph), making the 8026CTS far more productive. Tractive effort is 25kN (18.4 lb.ft)—12% better than the 8026’s main competitor. A dedicated boom and longer dipper arm provides superior digging, loading, and grading performance, with a maximum digging depth of just under 2.8m (9.2 ft). Tearout forces are more balanced for higher productivity, while a longer stroke dipper ram and revised dig end geometry enables the bucket to clean right up to the dozer blade. Bucket rotation on the 8026 is also best-in-class, minimising material spillage during loading. Controllability is greatly enhanced as well, with a new hydraulic valve block that delivers a 17% longer spool stroke. Low-effort servo controls are intelligently laid out, simple, and easy to use, while the new valve block technology allows for true straight line tracking while multi-functioning. To improve jobsite safety, the hydraulic system features full control isolation when the left hand armrest is in the raised position. This includes isolation of the dozer and tracks. O-Ring face seal technology optimises hydraulic system integrity. Electro-proportional auxiliaries make this machine even more versatile, when combined with JCB’s wide range of attachments. A new handheld tool circuit on the 8026 will power a range of hydraulic hand tools, including breakers, drills, pumps, and cutters. This reduces the amount of equipment an operator needs to bring to site. A bucket-to-grab changeover, similar to what is currently available on JCB’s 4.5t and 8t (5 ton and 8.8 ton) excavators, allows the operator to switch the oil flow from the bucket ram via a ball valve to the quick-release connectors. As a result, the main auxiliary line can operate the grab circuit, while the bucket service can operate the rotate action—a useful option that increases the overall versatility of the 8026. The automotive-grade cab interior includes a seat that slides further back for 50mm (2 in) more leg room, improving both access and comfort. With new rubber cab mounts, and a more refined cooling system, in-cab noise level is now 77db. Visibility from the cab to the working area is excellent, especially with JCB’s gull shaped rear bonnet at that eliminates blind spots. Serviceability is excellent with daily checkpoints grouped together for easier regular maintenance. Inside the engine compartment, owners will find an extra 100mm of space with color-coded hoses in the side-mounted valve block to speed replacement in the event of accidental damage. Service access to
the slew motor is also greatly improved via an easily removable floor panel. Access to the battery is also far more straightforward; it’s located beneath a new hinged cast tread plate on the cab step.

Mustang offers true zero-tail-swing excavators All five of Mustang’s new Zero-Tail-Swing Excavators—the 170Z, 270Z, 350Z, 450Z, and 800Z—are designed around a powerful and reliable Yanmar interim Tier IV engine to enhance engine performance and increase efficiency. The all-new excavators are true zero-tail-swing machines, with no cab overhang beyond the tracks in any direction. This allows the machine to operate directly against a wall or other obstruction without causing damage to the structure or machine. Mustang 270Z, 350Z, 450Z and 800Z excavators are equipped with a hydraulic quick coupler, which makes attachment changes as simple as flipping a switch. Plus, the pin grabber style hydraulic coupler works with the majority of attachments, making the excavator ready to use with the owner’s existing tools. The Hydraulic system on the Mustang ZeroTail-Swing excavators incorporates two variable pumps and two gear pumps. The pump oil flows are combined and redirected where needed, allowing for simultaneous operation without loss of hydraulic power. On the 800Z, an operator can save fuel when full performance is not necessary by reducing engine RPM by 10% using the Eco mode. The mode is easily activated and deactivated with a simple toggle switch. Mustang Zero-Tail-Swing excavators are equipped with rugged, high-strength booms constructed with a single boom-pin design; and thick side plates with internally routed lines. Heavy-duty cylinder guards protect exposed cylinders from damage. Longer, offset crawler tracks enhance stability and provide smoother travel. Tracks are short-pitched to reduce wear, fatigue and damage. The angled crawler frame reduces soil buildup on the undercarriage. The large, walk-through operator’s stations on canopy equipped models increase operator safety and comfort, and enhances productivity. An integrated boom light on all models illuminates the area being excavated, extending the workday when necessary. Easy to remove side covers and a large rear door allow access to all daily inspection and major maintenance points. In addition, the 170Z is equipped with a unique variable undercarriage that extends from 950mm (37 in) to 1,250 mm (50 in) wide. This allows the
machine to access narrow, hard-to-reach areas, and provides the ability to increase stability on uneven terrain. The extension blade easily expands to the same width for further stability. A full line of EDGE attachments are available to complement the Mustang line of excavators, including buckets, hammers, breakers, thumbs, and many more.
Volvo cleans up in the compact excavator class The all-new EC15C, EC17C, EC18C, and EC20C compact excavators from Volvo Construction Equipment set new standards of quality, technological innovation and value in the 1.5t to 2t (1.6 ton to 2.2 ton) class. They replace the EC15B in XR, XT, and XTV variants, and the EC20B in XT and XTV variants. Available worldwide, the new models are powered by a 12.3 kW (16.8 hp) diesel engine, and include hydraulic hoses routed in the boom as well as rear protection. The entry-level excavator in the new range is the EC15C. With a maximum operating weight of 1,540 kg (3,388 lb), this open-canopy model can be transported by a light vehicle. Built to access the smallest of job sites, it has a maximum digging depth from 2.1m to 2.3m (6.9 ft to 7.5 ft) and a bucket breakout force of 1,290 daN (2,900 lb.ft). The 1,650kg (3,330 lb) EC17C is fitted with the same fixed displacement 31 litre/min (1.08 cfm) hydraulic gear pump as the EC15C, but features a higher specification cab. The EC18C shares the same dimensions as the EC17C, but is fitted with a 44 litre/min (1.6 cfm) variable displacement hydraulic pump for increased performance and versatility. Able to operate a wider range of attachments, the EC18C has been specifically developed to meet the demands of rental customers, owner operators, a n d specialist contractors. The range-
topping EC20C is offered in both canopy and cab versions with operating weights of 1,850kg and 1,940kg (4,070 lb and 4,268 lb), respectively. Like the EC18C, it can be specified with a variable width undercarriage. This allows the compact operating width of 994 mm (3.3 ft) to be increased to a wide and stable 1,336 mm (4.4 ft). Both cab and canopy excavators meet or exceed TOPS, ROPS, and OPG1 standards of protection. Extensive cab glazing with narrow cab pillars and a compact rear design enhance all-around visibility. The operator can use an electro-proportional roller on the joystick to slow and

offset movements simultaneously. This enables these new C Series excavators to deliver faster and more precise performance. The attachment circuit and offset function foot controls have now moved to a button on the right-hand joystick, providing operators with more leg and foot room. A new instrument panel provides comprehensive information on all key operating functions. All models have a cast steel boom end and a cast iron arm end. Key hydraulic hoses are routed through the boom for optimum protection, with the rear counterweight acting as protection for the rear of the machine. Ease of operation is another design feature. As an example, the travel speed will automatically shift from high to low according to load. This ensures optimum productivity and traction retention when operating over steep terrain or in difficult conditions. It also ensures productivity can be maintained when conducting leveling work or backfilling. For safety, the models feature high-performance halogen work lights. A wide range of Volvo CE-approved accessories are also available for all four models. All have a simplified hydraulic level check with built-in diagnostic system. A single-piece engine hood provides unobstructed service access, while the instrument panel provides at-a-glance monitoring of all key functions. Cab floor panel lifts provide access to hydraulics and main control valve. Three built-in lift/securing points allow easy lift and transport. The EC15C and EC17C are fitted with a single high efficiency pump for all hydraulics. The variable displacement pump automatically adjusts oil flow to meet demand. A rounded profile dozer blade offer extended reach for optimum grading performance. The boom cylinder on the EC15C, EC17C, and EC18C is positioned above the boom for added protection. And, the EC18C and EC20C feature a load-sensing hydraulic system for fast cycle times, even when carrying out multiple functions. Full-size hydraulic travel pedals enhance comfort and operating precision. A digital hour meter that indicates total engine running hours can be viewed from outside the cab without starting the engine.

system has 10% to 15% greater cooling capacity. The improvements in engine horsepower and torque, coupled with a 6% increase in maximum pressure from the main control valve, translate into increases to various workgroup functions. Swing torque increased by approximately 8% to 11%, which allows the excavator to swing uphill more easily, as well as improve backfilling trenches. This leads to decreased time per foot of trench, improving productivity. Digging force has increased approximately 5%, which allows for more power in harsh digging conditions, leading to decreased cycle times and improved production in trenching applications. Lifting capacity is increased by approximately 2%, providing improved power out of the trench, allowing the machine to lift and place more material with each cycle. The boom-up speed improved by approximately 6%, which allows for more work to be completed faster, increased cycle times, improved truck loading time, and more material moved per hour. A variable geometry turbocharger (VGT) is utilised to increase boost pressure at lower engine rpm. Controlled by the ECU, the VGT varies the amount of boost supplied to the engine to optimise combustion over the entire rpm range. The VGT also allows the engine to generate a greater amount of torque in a wider band in the rpm range, increasing engine performance at lower

Doosan provides additional enhancements to DX350LC with interim Tier 4 updates The Doosan DX350LC excavator is more than just an interim Tier 4 compliant machine. Improvements span from more engine horsepower and torque to a turbocharger, upgraded cooling system, and new hydraulic system. The DX350LC is powered by a 210kW (281 hp), six cylinder D L08K watercooled diesel engine optimised for use with a cooled exhaust gas recirculation (CEGR) system, diesel oxidation catalyst (DOC), and diesel particulate filter (DPF). The engines in this configuration are optimised t o reduce nitrogen oxides; after treatment is needed to reduce particulate matter, the engine complies with interim Tier 4 emission regulations. The turbocharged 7.6 litre (466 cu in) engine features a common rail design with direct fuel injection, electronic control, and four valves per cylinder. The high-pressure common-rail (HPCR) system increases the efficiency of fuel delivery by increasing the pressure to 1,800bar (26,100 psi), allowing the injector to inject a finer mist into the engine. This results in a more efficient combustion as required by the lower combustion chamber temperature due to the CEGR system. Cooling system upgrades include two variable speed hydraulic fans that allow the engine and oil cooling systems to be controlled independently, improving fuel efficiency and providing a quieter operator environment. On average, the new cooling
engine rpm. This improves machine performance in the standard and economy power modes while saving fuel. The new closed center main control valve with electro-hydraulic pump control, exclusive to the DX350LC, allows the ECU to maximise engine power. This leads to an approximately 20% increase in efficiency of the main control valve, which leads to improved fuel economy. Workgroup performance increased approximately 10% compared to the Tier 3 DX350LC model. Smoother control and more accurate placement of materials is a result of the operator’s ability to control the machine with more precise movement. Additionally, the new boom float option allows the boom of the excavator to “float” up or down, allowing the operator to focus more on the task while decreasing the machine workload and increasing efficiency. The float mode allows the boom to move freely up and down without hydraulic flow. The breaker mode allows the boom to freely move down, only without hydraulic flow. A temporary reset button allows the ability to momentarily disengage the float, allowing hydraulic flow to activate the boom. Doosan continues to focus on operator comfort with further enhancements to ROPS cabin. Both a seat height lever and tilting function for the seat cushion allow the operator to find an optimum position. The cabin mounting mechanism has been improved with a thickened dampening plate, while a coil spring reduces cabin vibration by 20%, allowing

Extendable arm option on Bobcat E55 compact excavator provides 30 inches of additional reach Bobcat, the only company that manufactures compact excavators in the United States, once again brings innovation to compact equipment with the introduction of a new extendable arm option for the M Series E55 compact excavator. The extendable arm is a telescoping arm that provides the best of both worlds—power and reach. Operated through a rocker style thumb switch located on the joystick for fast and simple movements, the arm provides an additional 762mm (30 in) of reach, when fully extended. The new option is also the first extendable arm for compact excavators in this size class that allows the use of the hydraulic clamp and Hydraulic X-Change™ attachment mounting system. When retracted, the Bobcat arm delivers similar arm force (tearout force) as a standard arm. Should the operator need to reach back into the trench to clean out material or reach farther away from the excavation to
dump spoil, the arm can be extended an additional 762mm (30 in). Another appealing application for the extendable arm is truck loading. The operator can reach to the front or to the far side of a truck to effectively fill the load. Bobcat’s new extendable arm option also allows for the use of a hydraulic clamp, something not possible with any compact excavator extendable arm on the market. The clamp capability is a perfect solution for contractors wishing to pick up and place material such as rocks, landscaping materials, and debris in site preparation applications. The extendable arm’s benefits are particularly appealing for utility, municipal, and site preparation work, as it offers the compactness of a standard arm machine with the ability to extend when needed. Working in tight spaces, and on concrete and established turf, is possible without repositioning the machine. This saves valuable time and reduces the need for re-work. When digging utility trenches, the extendable arm ensures a long enough reach to move spoil away from the trench and out of the way, reducing the risk of the trench falling back into itself because of the weight of the nearby spoil. At full extension, the overall length of the arm also simplifies the task of creating flat-bottom trenches for water and sewer utility installations. Bobcat’s extendable arm maintains the versatility of operating attachments. A unique retention pin holds the arm in the retracted position, allowing use of up to 16 different attachments. Bobcat’s extendable arm also accommodates the optional Hydraulic X-Change mounting system, which allows for even faster attachment changes. Issue 3 • July - August 2012 •

Bobcat has launched the new 2.6t zero tail swing E26 mini-excavator, which offers increased stability, ensuring that it does not require an additional counterweight when configured with the optional long dipper stick. This increases the working range while still limiting the weight of the long arm cabbed version of the E26 to 2.7t to allow it to be transported by trailer. The E26 is designed to offer the operator a full 360° view around the machine with full sight of the right track and the rear of the cab. The wiper motor is mounted on the lower front window to provide superior forward visibility. The reduced weight of the strut-assisted front window makes it easier to open and close. The control system, which automatically monitors the engine and hydraulic systems and shuts them down in the event of a problem, also automatically turns off the work lights after 10 minutes when the key is not in the ignition to prevent the battery being run down. A battery kill switch provides enhanced security.

Jenny Products offers two-stage compressor
In the US Jenny Products has introduced the W11HGB-30P to its line of two-stage wheeled portable air compressors offering the highest air volume in its class, the company claims. The W11HGB-30P is equipped with an 8kW Honda GX-Series engine with electric start. It includes an 113litre ASME-certified air tank with a durable powder coat. The compressor produces 0.6m3/ min at 6.8bar or 0.5m3/min at 11.9bar. The W11HGB-30P is belt driven with a large flywheel and special unloading valves for easy start-ups and extra cooling, and a directional air shroud helps further reduce pump temperatures. For easy manoeuvring and positioning around sites, the W11HGB-30P includes two pneumatic tyres and convenient lifting handles. Other standard features include a manual tank drain, pressure relief safety valve, high-quality pilot valve, pneumatic throttle idle control, anti-vibration feet, and tank, regulator and outlet pressure gauges. Options include an oil sight glass, air line filter and lubricator. Additionally, different engines and pressure outputs are available upon request.
New Holland at Intermat New Holland used Intermat to launch several new products featuring the brand’s advanced Tier 4 interim solutions and celebrated the completion of 90% of its Tier 4 interim product range. New Holland showed the Tier 4 interim compliant machines with low fuel consumption and emissions. The company benefits from its collaboration with sister company FPT Industrial, which pioneered low emissions engine technologies, in particular, Selective Catalytic Reduction technology. This has resulted in New Holland’s SCR solution, which
features in many of the products. With New Holland’s SCR solution, Tier 4 interim emissions standards are met without particulate filter and exhaust gas recirculation. The optimised combustion delivers more power with less fuel, while the cooling and oil systems are not affected. New Holland’s product renewal programme is on schedule to complete its full offering of Tier 4 interim products by the end of 2012. Among the new products are the latest C Series crawler excavators and wheel loaders, including the 9t payload W300C, the complete four-model backhoe loader range and the compact LM625 telehandler. New Holland also previewed the new generation E140C SR short radius excavator, which will reach the markets later in the year. New Holland is also introducing its new telematics system, which will enable customers to track and monitor the performance of every unit in their fleet and optimise the utilisation of their equipment and resources.
New Holland has also extended its mini excavator range with the new top of the line 5.3t E55B SR. It shares the smart hydraulic technology that relies on three integrated pumps to deliver dozer operation, simultaneous movements, exceptional power and smooth operation under heavy loads. The machine tail only just exceeds the width of the tracks when swinging, combining stability and lifting capacity with the benefits of a short radius mini excavator. The short radius tail, together with the
exceptional digging depth and the smart hydraulic system that enables an upper frame rotation in less than seven seconds, results in extremely short loading cycle times and high productivity.

Gehl’s new skid steer loader Gehl has introduced the vertical lift V400 Skid Loader, claimed to be the largest skid loader in the world with an operating capacity of 1814kg and a vertical lift height of 3647mm. The V400 is a true vertical lift machine, as the lift path follows a vertical line, as opposed to an ‘S’ shaped path offered by competitive vertical lift models. The V400 can easily load high trailers and trucks and with an unmatched rated operating capacity, there are few jobs this machine cannot handle. “Gehl is excited to regain the throne as the world’s largest skid loader,” said Gehl product manager Sean Bifani. “The V400 fulfils the demand for a high capacity skid loader. Paired with its high lifting height, the V400 enters the high-end of the skid loader market, where product options are minimal. The V400 provides maximum capacity and the industry’s largest breakout force at 40.7kN.”
The V400 comes equipped with a Cummins diesel engine providing 442 Nm of torque and gross power of 74 kW. High system pressure, with optional high-flow of up to 154litre/min, is designed to handle virtually every high performance attachment. Standard HydraglideTM ride control allows the lift arm to float when transporting loads, minimising loss of material and offering increased operator comfort. The operator’s compartment features unsurpassed ergonomics and superior comfort. The standard level II ROPS/FOPS cab-forward design optimises the view to the bucket. A side folding restraint bar with adjustable armrests increases operator safety and comfort.

For many years Hydro-Tec has distributed been distributed the Pentruder concrete cutting systems in central and eastern Europe. Hydro-Tec celebrated its 15 years in business with demonstration days at their premises in Rednitzhembach, Germany. The Hydro-Tec team has been working towards this event for quite some time and the visitors were met by an impressive set up with a complete range of Pentruder products, Hydro-Tec’s own drill stands, diamond blades and diamond drill bits.
Showing the new Pentruder core drill system
The Pentruder MDU Core Drill - NTGRA got a lot of attention and the contractors were impressed by the power and ease of use of the drill motor. HydroTec has developed their own drill bits for high speed drilling with the MDU Core Drill - NTGRA, called Highspeed gold and Highspeed blau. The cutting performance and lifetime of the segments was very good. Hydro-Tec sales manager Helmut Windirsch demonstrates the SL-spindle for larger drill bits. Tractive personnel also demonstrated the SH-spindle for smaller drill bits. With the right drill bit a peripheral speed of 10-15m/s is no problem. Hydro-Tec sales manager Klaus Edenharter demonstrated the cable for single-phase power supply to the MDU Core Drill – NTGRA and showed that drilling with this electrical supply is also very efficient.

D-Drill acquires Highway Systems In the UK Highway Systems, which provides a method of stabilising concrete roads before resurfacing, has been bought out by diamond drilling and sawing business D-Drill. Highway Systems was founded in 1993 and utilises a cracking and seating method prior to resurfacing roads made of concrete, which can be up to 70 years old. Instead of digging out and removing the concrete, the company’s specialist machines turn the existing concrete into a flexible road base, which is then overlaid. The process is quicker and more economical than other processes and cuts down massively on labour and particularly waste costs. “Local authorities and councils are looking to make efficiency savings in all areas and so are the contractors Highway Systems can serve,” says D-Drill managing director Julie White. “This process is so much more economical in terms of cost, time and the environment that I thought it was a strong proposition and decided we should purchase the business. In terms of the costs, to totally reconstruct a concrete road to a flexible carriageway in the traditional way, you might be looking at up to £200/ m2. Using this system, it can be £5/m2 and that is better than a 90% saving.”
The system can only be utilised on concrete roads. “As soon as the cracking and seating process is finished the road can be driven on immediately and safely for up to six weeks before overlaying,” says Des Burns who will run the business for D-Drill. “Traditionally, excavating and reconstructing, for example, 10,000m2 of road would have taken weeks if not months before it could be used again. Using our system, we can have that finished and ready for resurfacing in around five-and-a-half days and the road can stay open during the cracking and seating process therefore no costly or inconvenient closures. “The process was discovered completely by accident on an airfield in Suffolk in the 1960s. The person cracked the concrete and left the job for a couple of days and when he went back, discovered that it had been turned into a flexible base after some of the planes had driven on it. He realised that he didn’t need to dispose of the waste concrete, but could re-use it as the base. That’s the system we use to this day and our machines ensure it’s a very smooth process and an even smoother surface afterwards.”

The
Managing airborne dust is an increasingly critical issue for demolition contractors around the world. But how much do you really know about it? Dust Control Technology chief executive officer Edwin Peterson explains to PDi’s Jim Parsons.
For as long as there have been demolition projects, there has been dust. Controlling it was not always among a contractor’s priorities. The measures taken were often intended to simply avoid a workplace nuisance or appease adjacent neighbourhoods. But as the health and environmental effects of airborne dust become better understood, control measures have become an increasingly mandatory project component, subject to regulatory inspection in many countries. And with the accompanying growth in on-site materials recycling, industry professionals must find ever more efficient, cost-effective methods of dust suppression.
What is “dust”? To make good decisions about how to most effectively deal with dust, it is helpful to know what it is and why it needs to be controlled, other than because a regulatory agency says so. Dust is a generic term for minute solid particles, typically less than 500 microns in diameter. In bulk material handling, these particles are often created in a wide range of sizes. Larger, heavier particles tend to settle out of the air, while smaller, lighter solids may hang indefinitely. For occupational health purposes in the US, airborne solids are categorised by size as either inhalable or respirable. The US Environmental Protection Agency describes inhalable dust as particles with a median diameter of about 10 microns. Larger particles in this category are typically trapped in the nose, throat, or upper respiratory tract. Respirable dust, usually identified as particles under 10 microns in size, is too small to see with the naked eye. These particles can migrate deep into the respiratory system beyond the Dallas Contracting successfully managed dust during a complex demolition of 16 cement silos by using two DCT DustBoss DB-60s at the Essroc Cement Plant in Martinsburg, West Virginia.

While atomised mist is affected to some degree by wind conditions, the system’s powerful fan and dense plume of droplets make it far more effective for outdoor demolition applications than electrostatic fog. Most contractors who utilized atomised mist allow for wind drift when setting up equipment for the day. But if conditions become too severe, dust management can be difficult regardless of which management approach is used. Though often compact in size, many spray atomisers are capable of reaching a very large surface area with powerful oscillating fans that can generate as much as 850m3 of air flow. These high-performance machines can have a range
of Dust Control of more than 60m, with 359º oscillating models delivering a high-efficiency spray that can cover as much as 1.16 hectares from a single location. Manufacturers frequently offer a carriage mount for easy relocation from one part of the job site to another. Units can also be tower mounted to increase the range and coverage area.
Specification guidelines The most obvious criteria in selecting dust suppression equipment is performance; how effectively does the system knock down solid particles suspended in the air and prevent ground-level dust from becoming airborne? One way to evaluate equipment is to review suppliers’ specification sheets and compare physical properties that affect the unit’s range and coverage area, such as, motor rating, air velocity, water volume and pump pressure. In most situations, the higher the numbers in these categories, the better. But statistical comparisons tell only part of the story. As dust particles and water droplets approach each other, for example, the best chance for a collision is created when they are roughly the same size. This prevents a slipstream effect that can carry them past one another. (See Figure 1.) Because all elements in dust control equipment must work together for maximum efficiency, each component must be designed to achieve an optimum balance. Changing a pump, nozzles, barrel, or fan can have consequences on droplet size, spray angle, pattern and range. Velocity is also critical, affecting range, coverage area, and surface wetting. Typically, higher air velocity produces smaller droplets and better wet-out, making a powerful fan advantageous. The nozzles must also be developed specifically for dust suppression to deliver the proper spray angle and pattern to achieve the optimum combination of droplet size and distribution. For these and other reasons, more and more contractors are finding atomised spray equipment to be the most versatile dust suppression option for demolition applications. Most designs are based around an electric motor, with smaller units often running on standard singlephase power and a garden hose water supply. Larger models typically require 3-phase service, and are fed by a fire hose. For specialized situations, some manufacturers offer designs with stainless steel or polymer nozzles and onboard filter systems that allow the use of potable or non-potable water. Larger designs will sometimes have booster pumps that can increase just 0.07bar of water pressure to 1.03bar or more, which has a direct effect on performance. To conserve water and energy, a solenoid-activated valve can be installed in the water line, allowing users to activate suppression equipment at specific times. For example, the solenoid can be activated by control lever or flow sensor to operate only when crushers or conveyor belts are loaded and running. The latest equipment designs can be automated even further to operate via programmable logic control, allowing a user to automatically start or stop machines when specific airborne particulate levels are reached. For site-specific applications, some manufacturers have developed tower mounts that provide improve targeting and delivery to high-dust areas, freeing up space for vehicle traffic or other equipment. The tower-mounted dust suppressor uses remote control for convenient operation or automation via sensors, while retaining full oscillation capabilities over a wide coverage area. Of course, no two demolition projects present the same circumstances and
challenges. That is why versatility is critical for contractors who work on a variety of structures Figure 1.

Consider a specialist… The most knowledgeable dust control equipment supplier is likely to be the specialist, a firm that focuses its experience, resources, and customer support on that single purpose.

users to carefully meter in surfactants to significantly lower surface tension. Even minute amounts of a surfactant can reduce the contact angle of pure water by more than 50%, producing greater numbers of smaller droplets and superior particle control. Beyond options and accessories, contractors should look for the ability to customise. Some equipment brands are sold with an established set of choices, with little room to accommodate specialized needs. For example, in some applications, the ability to tailor the droplets to suppress a very specific particle size can be a significant advantage. That kind of versatility typically means a change in nozzles, manifolds and/or other features, requiring a certain amount of flexibility that not all manufacturers will offer. Other system innovations have been developed by demolition contractors. One company’s engineers crafted a boom-mounted suppression system to significantly extend the unit’s reach and effectiveness in highrise applications, even as a structure is being demolished. This technique’s versatility and mobility helps prevent particles from becoming airborne, and reduces migration with its highly accurate delivery. Another contractor designed a completely self-contained, truck-mounted suppression system that matches high-efficiency fandriven suppression equipment with its own generator and water source. The 15,000 litre tanker incorporates a fully functional, high-performance oscillating dust suppression unit mounted on the back, complete with booster pump and adjustable elevation. Other features of the dust management truck include a custom 3-phase, 480V generator on the front, with the winding driven by a power take-off from the vehicle’s engine. The system will soon be operable by remote control.
…and be a smart shopper Before making a commitment to a particular dust suppression design, it is a good idea to see the units close-up and get a demonstration of the equipment in service. Do not rely solely on specification sheets and videos. Ask potential suppliers for references in your specific industry, and take the time to call them. Renting a unit before buying can also be a valuable experience,

especially if the supplier will credit a portion of the rental fee toward the purchase. Inspect the equipment’s construction. Is it built with heavy-duty materials that are likely to withstand the rigors of everyday use, or are thin sheet metal housings and light-duty components used? Does the supplier employ a durable frame and fasteners that lend themselves to removal and replacement, if a repair becomes necessary? Or, is the unit assembled with lightgauge rivets and sheet metal screws that are unlikely to survive many years of field service? Specifiers should also examine equipment with safety in mind. Does the unit have any exposed moving parts that could cause accident or injury? Are fan blades and motors protected by heavy-gauge housings or guards? How much noise does the equipment generate? These considerations may seem minor compared with performance, but it takes just one job site accident to illustrate the potentially high cost of ignoring potential safety risks. A supplier’s warranty and guarantee are also good indicators of the level of quality buyers can expect. Remember that the warranty is the manufacturer’s pledge to replace failed parts within a specified period of time, while the guarantee is that supplier’s assurance of a buyer’s satisfaction. A manufacturer willing to warranty products for significantly longer than its competitors is demonstrating confidence that the equipment is durable and reliable. Likewise, if a supplier promises customer satisfaction with a money-back guarantee, it is a good indication that the products have been field-proven to perform as advertised. The effectiveness and versatility of the atomized spray systems appear to be gaining popularity among demolition firms, representing a truly portable dust control option that delivers greater suppression efficiency than much larger fixed systems or manual spraying techniques, at a fraction of the cost. With public awareness and industry regulations in Europe and the US become more focused on reducing the demolition dust-associated risks, contractors need to be ready with the best systems, and the best knowledge, to serve their customers and communities.

Dust Control Technology has announced the introduction of a new component in its arsenal of custom solutions. This is a family of tower mounts for the company’s atomized misting equipment, which extends droplet hang time and range, while providing more precise aiming capability. Tower mounted units help commercial operations achieve superior particle control and prevent dust from migrating off-site. “The tower mounts can deliver a focused mist to the areas where dust is created,” said DCT general manager Laura Stiverson. “This allows the DustBoss units to concentrate virtually their entire output directly to the source of the problem.” Designed to withstand wind loads of at least 160km/hr, the towers are constructed of carbon steel pipe and hot dip galvanized to resist corrosion. To further customize a dust solution for individual customer sites and conditions, any of the fan driven units can be modified to address specific particle sizes or service environments. “In some applications such as slag handling, the dust particles can be so small that they are more effectively managed with smaller droplets,” said Stiverson. “In other situations, reduced flow may be preferred to protect moisture-sensitive materials.” In either case, the company can apply its variable particle sizing technology to match the dust to the most appropriate droplet size and water delivery. “The most effective suppression takes place when the dust particles and droplets are roughly the same size,” said Stiverson.
Towers in three sizes Three tower sizes are currently available. The 150mm base tube is generally employed on tower heights under 4.5m, and is compatible with the standard oscillation package. For greater elevation, 200mm diameter towers are used. The heavy-duty design is the 250mm diameter flange-mounted towers, which are secured directly into concrete. Available in heights up to 6m, the large diameter allows hoses and power cords to be routed inside the tower for protection. The flange mounted units feature programmable oscillation, with a customer setting range from 0-359º. Climbing rungs, work platforms, booster pumps and additive metering systems are all available as options. Once installed, users have two options for raising and lowering the tower. The manual jack has a long handle attached, allowing operators to rotate the handle to change the height from the ground. When fitted with the optional electric jack, changes can be made via the control panel or remote control unit. The ability to network multiple machines and/or automate the on-off cycles can be a big advantage to large operations.

Demolition of Ital motorway viaduc Panoramic view of the site at an advanced stage of demolition
With special demolition machines and radio-controlled equipment, Italian demolition contractor Armofer demolished the reinforced concrete structures of the E45 motorway viaduct in Emilia Romagna.
The Volvo EC290EC is lowered to the ground with a crane.
Snow, cold and ice imposed extreme operating conditions on the project, but did not slow down the works, which were completed by the Siziano based firm on schedule. The demolition proceeded in an identical manner to its construction, but in reverse. After the mechanical dismantling of the viaduct’s keystone from its deck, the gradual deconstruction of the deck itself was carried out segment after segment, gradually receding towards the pier-head. This operation occurred in alternate steps on both sides of the pier-head. The viaduct’s support was demolished in the traditional way from ground level with the excavator in demolition mode, reaching up to the deck with boom up to 33m in length and also from the deck using remotely controlled equipment.
Radio controlled demolition and video observation

During the demolition phase, no one was allowed on the deck, which was 120m long with 60m cantilevers each side, Armofer chose to use Volvo excavators and equipped an EC290C and EC235C with remotely controlled technology. This enabled the machine operators to complete and control the demolition from an appropriately positioned platform. Even though Armofer’s team was using an aerial platform, there were occasions when visibility, at the highest 100m point of the viaduct, was limited. However, Armofer continued with the project by setting up a remotely operated, radio controlled system to execute the work. Armofer’s site manager Ruggero Gregorini, developed a

While receding towards the pier head, the demolition works became progressively more and more demanding due to the large number of tensioning strands. The demolition hammer was necessary around the pier

PERFORMANCE IS IN THE DETAILS
The concrete consistency near the pier head required the use of a remotely controlled hydraulic hammer head area and was used jointly with the excavator due to the high level of structural reinforcement. Afterwards the remotely controlled excavator was lowered to the ground with a crane, and the pillar was then progressively torn down, aided by the video monitoring equipment.
On time despite tough weather “We were perfectly on time despite the adverse weather conditions. Demolishing highway viaducts is always a complex operation, both from a structural and organizational point of view,” says Armofer site manager and special equipment operator Ruggero Gregorini. “These concrete structures are strongly reinforced, especially near the supporting pier head. Powerful technology and equipment must therefore be deployed. Furthermore, the height and intrinsic danger of the work obliged remote operability and greater technological control. In this instance, we had to deal with problems related to the very low temperatures caused by the ice-cold winter. The abundant snowfalls at the beginning of the year forced the site to close for a few days, in the following days the worksite was accessible but temperatures were extreme, to the point that ice had formed on the deck. This made the movement of crawlers on the deck, which was cantilevered in space, even more dangerous. The support greatly oscillates when hit by a mechanical arm or simply when heavy-duty machinery moves about on it. The presence of ice complicated matters as the tracks slipped on the frozen surface. We built a cabin around the aerial work platform so as to protect it from the cold and guarantee the operators the best working conditions. This is where we housed the video control system and the real time data transmission monitor.”

High-Cycling Into the Future Wall and wire sawing techniques have been around for about half a century. All this time concrete cutting hardware has been evolving: going down in weight and size, going up in performance and getting easier to control, thanks to various electronic gadgets. How much more advanced can it get? Has the market reached a saturation point? Is there any room for new entrants? Andrei Bushmarin attempts to answer these questions in PDi’s annual wall and wire sawing survey. If we take a bird’s eye view of the concrete sawing industry, we cannot help noticing that it is dominated by a handful of European-based companies. Swedish, German, Austrian and Swiss manufacturers have all but cornered the global market and the situation is unlikely to change in the foreseeable future. The fact that, historically, Europe has been at the forefront of machine design might have something to do with its domination. Admittedly, there are some serious players in Asia too, but unlike the diamond tooling business, their presence in the hardware sector is rather modest. The manufacture of concrete cutting equipment is a technology-intensive process, which demands a great deal of engineering expertise. That alone prevents proliferation of competitors in the field. After sales support is getting increasingly important, and that further narrows down the number of players who have resources to provide it on a global scale. It is safe, therefore, to regard the market of
concrete sawing machinery as well established. This being said, we believe that a new company with a fresh innovative approach still has opportunities to challenge established manufacturers. To get an insight into the wall sawing industry’s trends, PDi surveyed all the leading manufacturers about the technical and marketing aspects of the business. Their feedback was used as the basis for this report.
Shift towards electric systems One of the most obvious trends is that electric and high cycle machinery is steadily gaining ground on hydraulic systems. All respondents were unanimously agreed on that. It is the future role of hydraulic equipment where they slightly differed. Some like Tractive and Braun believe that hydraulic equipment will be extinct in many markets in a few years’ time. In Europe, this process is already well underway. Even in less advanced economies like Russia, contractors begin to appreciate the advantages of electric machines, points out Braun’s product manager Siegfried Uebleis. This view is echoed by Tyrolit marketing manager Christian Bruner, who confirms the shift towards electric systems in some non-European countries. Still, hydraulic saws remain popular, especially in places with obsolete electricity grids and nonexistent technical support. Besides, there are special applications where they prove indispensible, for instance, in underwater cutting. Hilti’s Olivier Zwick sums up the opinion of the majority by saying that hydraulic equipment will continue to exist in years to come, but its market share will drop to insignificant levels.
What a customer wants Concrete cutting is a customer-oriented business. To stay competitive, a manufacturer should work in close contact with end users, heeding their needs and requests. What do customers expect of their equipment and suppliers these days? First of all, they want reliable, user-friendly and lightweight equipment. A machine that boasts a winning combination of power, reliability, low weight and affordable price is what every contractor is after. Good after sales service is the next item on customers’ wish lists. A savvy supplier sells a customer more than just a wall or wire saw and offers a long-term partnership that includes top-notch service and consultancy on the customer’s projects. The third important factor is the cost of machine ownership. A sturdy high-performance
54
PDi • Issue 3 • July - August 2012
machine allows the user to keep operating costs down, which is for many the bottom line of equipment ownership.
Go West Again The survey has made it evident that industrial nations with well-developed, stable economies remain the biggest consumers of wall and wire sawing solutions. Scandinavian and German speaking countries lead the way, followed by North America, the UK and Australia. The BRIC countries are customarily viewed as the huge and very lucrative market, but demand grows slower than expected there, hindered by socio-political and economic problems. Middle East and South America are regarded by most of the respondents as largely untapped territories. Industry-wise, the nuclear power segment offers an excellent opportunity for manufacturers of concrete cutting equipment, believes Siegfried Uebleis. Following the Fukushima disaster in Japan, some countries have reconsidered their policy on nuclear power, which resulted in the decision to decommission or modernize their nuclear facilities. This is bound to create substantial demand for concrete sawing machinery in the upcoming years.
Husqvarna upgrades electric range Husqvarna’s high cycle saws WS 440 HF and W 482 HF have undergone an overhaul, which resulted in increased performance and reliability of the machines. The saw heads incorporate new electronics, as have electric power packs that now feature new motherboards and updated software. Made in aluminium, the new blade guards are robust, durable and easy to handle. The wireless remote control with a 89mm colour display and intuitive interface allows for comfortable remote operation. The new parts and accessories are fully compatible with the existing WS 440 HF and W 482 HF.
New arrival in Dr. Schulze’s HF family Dr. Schulze’s electric model SW800E has got a new power pack that enhances reliability of this HF wall sawing system. Reliability of electric saws has been a matter of ongoing debate in the industry. A voltage drop may cause massive damage to the drive and control components of an electric
reaches 18m, which allows making long cuts without interruption. The saw features a pneumatic wire tensioning mechanism, which enhances the cutting performance through optimum tensioning. This system runs on 3x400V and 63A input power (a 480V version is available for North America).
EDT bundles up safety features into package EDT Eurodima has finalized the development of a safety package for its high cycle range. The package, which is branded Total Safety Control, consists of three key elements. First, the control units of the braxx series BC120, BC201 and BC321 are geared towards shorter cycle times. This prevents the motor from overload. The second element is a safety clutch installed in a predetermined breaking point between the HF motor and the saw head to protect them both. A new slip clutch that safeguards the gear from the thrust of the material completes the safety package.
saw. Dr. Schulze has solved this problem by introducing a number of features that provide multi-level protection of the HF drive. Designed and built in-house by Dr. Schulze, the PowerBox HFB 180 boasts a stainless steel housing with the vibration-cushioned feet and an outside mounted radiator for cooling. It is equipped with a motor detection system, which is able to recognise different types of HF motors. The safety features include a switch that prevents the machine from turning on if cables are connected incorrectly or incompletely, power and phase failure protection, temperature gauges for all relevant PowerBox and HF motor components, and overload protection.
Skystone adds an Asian touch
New P2-technology for Tyrolit’s premium saws The new premium-class electric wall saws WSE2226*** and WSE1217*** from Tyrolit Hydrostress feature P2technology, which is based on the principle of drive motors with permanent magnets. The new technology is said to combine the advantages of electric and hydraulic drives. Reduced motor speed minimizes the strain on the machine components, while increasing torque and overall efficiency. This, in combination with optimized size and weight, leads to reduction in service costs and increased maintainability. The 26kW WSE2226*** which accommodates up to 2.2m diameter blades, can perform a wide variety of tasks. The new automatic feed enhances the saw’s performances, especially on heavily reinforced concretes. These two innovations are built into the other machine, the 17kW WSE1217*** designed to handle up to 1.2m diameter blades. True to Tyrolit’s principle of modularity, both models can be used with the manufacturer’s proven VAS railing system.
Rail-guided channel cutter from Otto Baier The German manufacturer of power tools Otto Baier, has developed an ingenious solution for automatic chasing of concrete walls and floors. Moving up and down a rail, Baier’s new machines, the BRS 512 and BRS 513, can slice the concrete off a wall or floor using multiple diamond blades. Cutting is done at a speed of about 6m/ hr to a depth of 32mm and a width of 50mm. This fully automated system is perfect for operation in contaminated areas, where the presence of personnel is not allowed due to safety reasons. The new system is equipped with a dust removal unit. The manual version called BDN 511 carries up to 11 diamond blades for high-performance cutting. The BDN 511 can be used with or without a guiding system.
Braun’s “antiballistic curtain” to safeguard operators Safety of wire sawing operations is a hot topic in Europe now. It has been prompted by a number of accidents, which had serious, sometimes even tragic, consequences for opera-
tors. When a diamond wire breaks, beads and connectors may get detached and go flying around, hitting operators and anyone who happens to be on the site. To prevent this, Braun has come up with a simple but efficient device, which it calls “antiballistic curtain”. Placed in front of the wire saw, it safeguards operators against detached pieces of the wire. The speed and penetration force of a flying diamond bead are equivalent to those of a shot fired from a shotgun, and tests have shown that the curtain is quite capable of withstanding it. Another innovation from Braun is the compact wire saw SSP 12-HF with fully automatic drive system. This type of equipment is becoming increasingly popular with contractors all over the world. In some countries, like Japan for example, a majority of concrete cutting jobs is done using compact machines. The SSP 12-HF, powered by an 18kW HF drive system, has a wire storage capacity of 12m, which allows for cutting of up to 8m2 of concrete without having to shorten the wire.
Hilti goes for power In early 2012, Hilti launched its most powerful electric wire saw so far the DSW 3018-E. With an output power of 30kW, the new machine is capable of demolishing over 10m2/hr. This high rate is ensured by two 15 kW electric motors moving the wire over the pulleys with a speed of 35m/s. The DSW 3018-E is designed for heavy-duty jobs or large-scale projects that have to be completed to a short deadline. According to Hilti, one of the best things about the DSW 3018-E is that the wire lifespan is not compromised by high cutting speed. The machine’s wire storage capacity
The Chinese manufacturer Skystone Diamond Tools belongs to those few Asian players that develop their own concrete cutting hardware. Established in 1994, Skystone focuses on producing diamond wires and wire sawing machinery for the stone and construction industries. The company builds some 300 wire sawing machines a year at its Fuzhou plant, which it supplies to many countries. Skystone’s bestselling wire saw is TSY-15, which is a compact 15kW machine, suitable for stone and concrete applications. According to Skystone, Japan and South Africa are the biggest consumers of this type of equipment.
Modularity is the future? Opinions varied on the issue of modular systems, which are often considered as the future of the concrete sawing industry. Some market leaders question this, listing complicated interfaces, lower performances and reduced durability among the drawbacks of modular solutions. According to Hilti’s Olivier Zwick, specialised wall and wire systems finetuned to a specific application will be a tool of choice for professionals. Nonetheless, modularity remains a focal point for many manufacturers, and development of modular systems will continue. Remotely controlled equipment with disposable parts for jobs in contaminated zones is another area for designers to zoom in on. If the nuclear industry proceeds with the cutbacks as planned, concrete cutters will be in for a very busy time. This task will require the machinery that is capable of withstanding extreme working conditions and can be disposed of once the job is done. Issue 3 • July - August 2012 •

OILQUICK SALUTE
The family owned manufacturer of hydraulic quick coupling systems OilQuick, is a vibrant company, which celebrated it 60th anniversary this summer.
factory, which over look the town and the Baltic Sea, were built a couple of years ago with open and light offices and production areas, state-of-the-art production facilities and testing areas. There is ample space for future expansion. The company keeps a large stock of complete quick coupling systems and spare parts. “When a customer needs one of our systems or a spare parts he wants it directly and doesn’t want to wait for it. That is why it should be ready on the shelf here in Hudiksvall. We are just as fast to work with as our quick coupling systems,” says OilQuick chief executive officer Henrik Sonerud.
In PDi 2-2012 a feature on hydraulic quick couplings compared the performance of different systems that can make the everyday tasks much easier for contractors. Those contractors with the need to continuously change attachments, without leaving the cab, will find an OilQuick system worthwhile.
What a Blast!
Stay competitive with quick tool changes Contractors working with demolition and recycling are two examples, if they want to compete that have a need of OilQuick systems for their machines. With the fast development of the demolition and recycling industries, quick tool changes will be a necessity to stay competitive. With an OilQuick system the right tool for the application is used, as the changeover does not hinder the work. Also the system has a closed circuit, which means no oil leakage resulting in an environmentally friendly operation.

That anniversary day started with lunch and a special dish from the region called ‘kolbulle’, which translated means charcoal ball. It is a thick pancake containing pieces of smoked pork and cooked in a pan over a charcoal fire. Kolbulle is eaten with different types of jams made from wild berries. The event started with a tour of OilQuick’s premises, including the assembly plant, testing laboratory, quality control, storeroom and offices. Former OilQuick president Åke Sonerud gave a presentation of the company’s history and revealed a little of future plans. Later each of the OilQuick quick coupling systems where demonstrated, which was followed by the anniversary ceremony, which included a blasting salute by two 16th century cannons. The festivities continued with tasting of Oil Quick’s own lager, followed by dinner and entertainment from the well known Swedish group Östen med Resten.
Fast growth during the last decade Most demolition contractors in Europe know the OilQuick quick coupling systems and the company has gained market share in the last 10 years. The company has grown from a start with just six employees to a current workforce of 30. OilQuick has doubled its turn tenfold during the same period and is reporting around EUR 14M for 2011. About 80% of production is exported to countries like Germany, and Switzerland. The Nordic region is a very strong market, but the company is in particular growing in Japan, Australia, England and France. There are currently about 10,000 OilQuick systems working around the world.

What Powers the Industry? Comparing a motor to a human heart is an age-old metaphor, but one can’t help it. Just like a person’s life cannot be sustained if his heart has stopped beating, the most advanced stateof-the-art machinery is little more than a pile of well-engineered junk without a motor to drive it. PDi’s Andrei Bushmarin reports on engines and motors that power concrete sawing and drilling equipment.
In the concrete sawing and drilling industry, many companies market various motor technologies, but the number of those that actually develop them is much lower. Devising motors for sawing and drilling applications requires special expertise and dedication. The specialisation pays off very well, though, for there is always a demand for reliable motor solutions in the machine building industry. The manufacturer Weka, which we begin with, is a legend in concrete drilling. Many manufacturers use the company’s drill motors, which it supplies either under its own brand or on an OEM basis.
Weka extends the acclaimed SR series Weka, based in Germany, is probably the most recognised brand in the drill motor segment. Founded in 1988 by Wilhelm Wurster, the company has acquired a reputation among its peers for making motors of outstanding quality and reliability. This helped Weka build an extensive network of dealers and distributors covering most of the world. Now the German manufacturer is launching a new drill motor, the SR 65S that extends the acclaimed SR line-up. The new model is a highspeed variation of its predecessor SR65. The motor, which is designed for 80-330mm drilling jobs, operates within a wide speed range spanning 260 to 560revs/ min. Weighing in at just 14.7kg, the SR 65S is primarily intended for deep drilling applications. The new model shares a number of common features with the other two SR series motors SR 65 and the smaller SR 25. They include 6 motor set-ups, which can be pre-selected and changed during operation using an operator keyboard, an LCD display, a carrying handle and splash waterproof housing protection class IP55.
Integrated solution from Tractive The Swedish company Tractive is another major manufacturer that places much focus on the development of its own motors. By integrating the electronic drive unit and the drive motor in the main housing, Tractive has eliminated the need for a separate power box and cables. The system can run on either one or three phase, with 3kW and 9kW output power respectively. Three spindle gearboxes allow for drilling speed to vary in a range of 100 to 1,440revs/min. All spindles are available with different spindle threads or the patented Quick Change Coupling. The system has 29 electronic gears that can be adjusted during the drilling and a reverse gear for removing the drill bit or extension rod. Complete with the spindle, the unit weighs 18kg.

EDT announces new generation of HF motors EDT Eurodima, in cooperation with the Austrian University of Technology, has developed the new high frequency motor SB321m. The model is said to herald the next generation of HF motors thanks to the improved frequency converters. They reduce the motor’s idle power, while simultaneously increasing the effective power at the blade by 3.5%. The motor’s cooling system has been redesigned to increase the cooling surface. Another feature of the SB321m is new bearings, which are more stable at high revolution speeds and less sensitive to temperature

Otto Baier enters the dry coring segment The techniques of dry coring and sawing are becoming increasingly widespread. There are several reasons behind the shift towards dry systems. Industries and applications where water is off-limits, such as nuclear power plants, is one of them. Environmental issues, like slurry generated by wet techniques, also remain the industry’s ongoing concern. German company Otto Baier has joined the trend by developing a model for dry coring of heavily reinforced concrete. The new machine BDB 825 has already proved itself on several demanding jobs, one involving drilling holes in an industrial stack at a height of 128m With a weight of only 5.5kg, the drill motor has a torque of 24Nm, which is indicative of its considerable power. The BDB 825 is fitted with PRCD, a LED overload indicator, and an integrated electronic overload relay. A soft-start function makes the drill-in stage of work nice and easy.
power to heat. Motors with permanent magnets operate most efficiently at low speed and Tyrolit has used this characteristic as the basis for its P2® technology. Lower motor speed put less strain on its working parts, which results in increased service time. In case of Tyrolit’s new electric wall saw WSE1217***, the motor speeds are so low that for most cutting jobs no gearbox is necessary. The high level of motor efficiency allows Tyrolit to build small and lightweight yet very powerful machines. So far only two models, the WSE1217*** and the WSE2226*** have been equipped with the P2® technology. But Tyrolit is confident that more will follow shortly.

New servo drive for Demco’s HF saws A year ago, Switzerland-based Demco Technic presented a new servo drive for wall sawing systems. According to the manufacturer, the device has a number of advantages over conventional HF drives, including higher performance, lower power consumption, compact design and peak torque at low speed. The 18.5kW servo drive operates with both 32A and 16A power supply. Low motor speed, compact design and reduced working temperatures result in longer maintenance intervals. The speed to torque ratio makes the new drive optimum for wire sawing applications. Demco’s 16kW Captor has become the first to be upgraded with the new servo drive. This year, the Swiss company is going to unveil a combi-system consisting of the Captor and a new wire saw.

New fibre installation method involving diamond equipment The time, when fibre installation was expensive and complicated, is gone. Thanks to a completely new method and technology, broadband over fibre can be installed faster, simpler and cheaper than before. The first commercial pilot project in Swedish company Skanova’s access network has recently been completed. “We see a large potential in using the MTT-method to extend the number of areas with fibre access,” says, Skanova
vice president for infrastructure Kaj Werner. During October and November 2011 a commercial pilot project using micro trenching was carried out in Skanovas access network in Nässjö, Sweden. The heart of micro trenching technology is the patent pending method and its supporting services owned by the Swedish company DellCron. Thanks to the unique design of the method, the project could be carried out with only minor disturbances to traffic and residents, although the installation was done along a main street with heavy traffic.
Fast, easy and cost effective “This method opens up for making fibre installations in areas which otherwise would be excluded because of high costs for excavation and restoration,” says Kaj Werner. Skanova is constantly looking for new ways for reducing the cost for installation. DellCron’s method is expected to have a very large potential in the areas suitable for MTT. “A prerequisite is that the communes and county authorities are positive and can accept the restoration method used in the MTT-method,” says Kaj Werner. “Some communes have been worried that the restoration of the street will not last. We at Skanova judge that the restoration is of high quality. We will extend our activity with other commercial pilots using the MTT-method in the communes, allowing it. In 2012 we plan to identify a number of areas specially suited for the MTT-method. We are satisfied with the results from Nässjö and we will continue to evaluate the method in other environments.” In the MTT-method a narrow trench is sawed in the

pavement or the street and at the same time a number of specially designed ducts for fibre cables are laid down in the bottom of the trench. Depending on the size of the used ducts, up to 20 ducts can be placed in the trench at the same time. “Now after several years of development, we are looking forward with confidence to see how our micro trenching method will be received by network owners, road authorities, and house owners,” says DellCron technical director Hasse Hultman. “Specially in areas with detached or semi-detached houses a new industrialised method for fibre to the home installations is needed, and that is where our environmentally friendly technology is ideal. However the method works just as well in dense urban areas, as it gives large cost reductions compared with traditional excavation.”
A completely industrialised process To saw a trench in the pavement or street and put down a number of ducts may seem trivial, however DellCron’s MTT method is much more than that. It is a completely industrialised process, from the detection of existing cables and ducts in the ground to automatic documentation of the installation using GPS. “In large network projects there are some essential areas of expertise that may not be neglected, particularly when introducing a new highly industrialised deployment method,” says Hultman. “First the network must be planned in accordance with the chosen material and the chosen installation method. Secondly, production planning must be made in such a way that a rational installation process is achieved. The installation must be planned so that the sawing machine is optimally utilised and other installation steps must be adapted for that. Very thin and/ or old cracked asphalt may be a problem, because of the weight of the sawing machine. For the few metres where asphalt is expected to be of low quality, the problem can be solved by laying out metal plates on the ground.”
60 to 90 m/hr The first step in the MTT method is to saw a trench through the surface layer of asphalt or concrete and into the underlying bearing layer. The trench is, in the current version of the method, about 20mm wide and 380mm deep. While the trench is being sawed, and before the trench’s sidewalls are allowed to collapse, a number of ducts for fibre cables are installed together with a search wire in the bottom of the trench. The search wire is used for future detection of the route for the ducts. The production capacity is at the moment 60-90 m/hr, depending on the sawing conditions. The ambition is to improve the production capacity. In the close to dust free and environmentally friendly sawing process, most of the sawed material is automatically collected in a big replaceable bag in the front of the carriage. The road sawing machine can cross streets without any major obstacles for the traffic. The traffic is released immediately after the sawing machine has crossed the street and the open trench may be crossed by traffic. Branches to properties are either made using a handsaw or a small road saw and are preferably made after the main trench is made. The restoration process is made in two steps. First the trench is filled with a tested and approved
material that is fluent at the time of filling and flows down and fills every cavity. The material cures and hardens and stabilises against compression, and remains possible to dig with a shovel, if needed. In order to achieve a watertight seal, the top 40mm to 50mm of the trench is filled with bitumen based sealing material. Text: Jeanette Waax
Background Facts DellCron has been developing a system for Fibre-To-TheHome (FTTH) in areas with detached houses and for city installations since 2008. The system is called the MTT-system and it is a complete system containing all machines, tools, components and software. The system also contains detailed descriptions of the various steps in the method. DellCron presented the MTT-method during FTTH Councils conference in Milano in February 2011 and the same year DellCron was elected “Fibre company of the year” by Skanova. DellCron also participates in working group for broadband under Ministry of Enterprise, Energy and Communications. Patents are pending for the MTT-method as well as for certain separate solutions.
Standardisation and quality recommendations In conjunction with fibre deployment in areas with detached or semi detached houses FTTH, operators and network owners depend on cost-effective and rational work processes and installation methods. Such processes and methods must not compromise QoS, security features or environmental requirements required by operators, network owners, service providers and end customers. Furthermore, road managers, city councils and local governments must be assured that new methods conform to reasonable requirements both in the work process and in the restoration of the road surface. With gaps in research and development, standardization and quality recommendations, it is not clear which requirements to use for Next Generation Access Networks NGA / NGN. A large-scale, rational and efficient implementation process, with the goal to within 10 to 15 years connect the majority of EU buildings to a new or upgraded infrastructure, requires verified and quality assured technical solutions and working methods. An example of this is DellCron’s ongoing development of a Micro Trenching solution, the so-called MTT method where over the last recent years several studies / reports have been made and extensive testing of the technology has been carried out in order to verify and adopt the technology for industrialization. The intention is to become an accepted and approved national standard, possibly even an international standard. DellCron’s technical director Hans Hultman leads the development in consultation with government agencies, manufacturers and operators. Work is expected to be completed in early 2013 and will result in detailed process descriptions with defined requirements.

Stanley makes an entrance to the Golden Gate Bridge In the US state of California the 2.5km long Doyle Drive road, which connects the famous Golden Gate Bridge with San Francisco was closed on Friday, 27 April at 8:00pm local time until Monday, 30 April at 5:00am for demolition to make way for a temporary bypass. Eventually the temporary bypass will be replaced by a more seismically stable structure called the Presidio Parkway and is scheduled to open by the end of 2015. Doyle Drive is the southern approach to the Golden Gate Bridge that opened along with the bridge
in 1937. It had been identified as one of the most seismically-unsafe roads in California. The California Department of Transportation shut it down and began tearing down pretty much everything between Highway 1 and Marina Boulevard on a Friday evening, and reopened the area with a temporary bypass the following Monday morning. During demolition, hundreds of joggers, dog walkers and spectators lined the construction zone to take in the interesting and unusual show. Cheers were heard as giant excavators, their hydraulic arms fitted with
various attachments, knocked down Doyle Drive with agility and speed. In the middle of the 24 hour demolition was Stanley LaBounty. One of the contractors on the project, Ferma Corporation, a longtime LaBounty customer operated 12 different LaBounty attachments on this job. These included metal shears, concrete demolition universal processors, large pavement breakers and LaBounty’s newest concrete demolition attachment, the MDP30 mobile demolition processor. A total of 65,000t of concrete was demolished and removed to make way for the temporary bypass. Stanley LaBounty has over 35 years experience in customer-driven product design, engineering innovation and service. It provides metal and concrete demolition and recycling attachment solutions for general contractors, scrap metal recyclers, demolition experts, heavy construction engineers and bridge contractors. “On this job our demolition attachments enabled the operators to work with agility and speed. Once sites like these are cleared, our metal shears can further process the scrap in preparation for recycling,” says Stanely LaBounty infrastructure solutions president Barb Popoli. “The demolition portion of the job had to be done in 24 hours so it required they have the right tools on site. The LaBounty Shears, universal processors, MDP and the Stanley MB100EXS breaker worked nonstop allowing the contractor to finish ahead of schedule,” adds Stanley
LaBounty western regional manager Bob Stuppy.

Through its alliance partnership with the Occupational Safety and Health Administration, the Concrete Sawing & Drilling Association has released a Best Practice on two hot topics of aggressive driving and road rage. Representatives from the CSDA Safety Committee have worked with OSHA to produce CSDA-OBP-1009 Aggressive Driving and Road Rage, the tenth document to be released by the Alliance since its formation in 2006. It is hoped that the release of this document will help professionals in the concrete sawing and drilling industry avoid confrontations as they travel to and from jobsites, or during their commute to and from their homes. “Many CSDA contractors travel around the country in work trucks, and sometimes they and other road users do not understand the extra time needed to manoeuvre such large vehicles or the distance required to bring these vehicles safely to a stop,” says CSDA safety committee chairperson and board member Kellie Vazquez. “By not understanding these factors, drivers can quickly become aggressive toward each other. In extreme cases, something as simple as not using a turn signal can result in an act of road rage. That is why we felt it was important to educate the industry about how to steer clear of these situations.” According to the American Automobile Association, aggressive driving behaviour is a factor in up to 56% of fatal crashes. When this percentage is applied to the average number of fatal road accidents across the US each year of around 38,000, based on data compiled by the NHTSA, it is clear that everyone should be doing what they can to eradicate aggressive driving and road rage from the nation’s roadways. CSDA-OBP-1009 details some of the factors that can lead to aggressive driving and road rage then goes on to explain some of the ways employers and employees can reduce instances of either occurring during their time on the road. This is the third roadrelated Best Practice released by the OSHA/ CSDA Alliance, having previously released CSDA-OBP-1001 Highway Work zone Safety and CSDA-OBP-1007 Distracted Driving. All three documents are available to view or download on the OSHA Alliance page of the CSDA website in English and Spanish.
