“Recession comes as a thief in the night”

Words from O’Brien

IACDS Returns to Its Roots

THINGS ARE STARTING TO COME BACK to normal again after the German exhibition Bauma that attracted about half a million visitors and over 3,000 exhibitors. By ”normal” I mean a buoyant construction industry throughout the whole of Europe and in the majority of the European countries there is still no sign of recession. This is perhaps best illustrated by the real estate market, which has been experiencing a dramatic increase in prices for residential property all over Europe. The increase started in the big cities before spreading to the medium size ones. Now the market has come to a point where prices have increased in the most remote places, which to some is a sign that the increase will start to slow down and perhaps halt in the big cities. I have experienced this as I come from a remote area close to the Norwegian boarder in the south west of Sweden. Here prices have stood still for ages. There are few industries offering jobs to people, which force many to move to other cities to work, including myself. Also the population is much the same now as it was when I was born in the 1960s. But now suddenly it has changed. The community is booming, new businesses are starting and property prices have increased around 15% in the last year. But is this a clear sign of a coming change? - a change that as some predict will come as a thief in the night. Parallel to this the European banks are holding down inflation by slowly increasing interest rates. The rise is already starting to affect households and companies that have no buffer. But I must not be pessimistic. When looking at the building and construction industry many new developments like infrastructure projects, housing schemes, shopping centres and factories are being planned, which bring new jobs to concrete cutting and demolition contractors. Our contractors are meeting the demands by investing in new and more efficient equipment, more personnel and training. The manufacturers PDi contacted after Bauma all describe a booming market where the biggest problem is the extended delivery time for products to their customers. Material suppliers to manufacturers have difficulties in delivering, which creates knock on problems for contractors. For example contractors can currently wait up to nine months for delivery of a mobile concrete crusher. If we are to believe that “recession will come as a thief in the night” contractors might not have the need for the equipment they have ordered if delivery time is that long. But again, I must not be pessimistic. Enjoy this issue of PDi and enjoy summer!

PDi • ISSUE 3 - JUNE - AUGUST 2007

The 2007 IACDS annual meeting returned to Germany. This was fitting and historically significant, as Germany was where IACDS was formed in 1995. In that year, the visionary leaders from associations in Austria, France, Germany, Switzerland, the United Kingdom and the United States who wanted to create an international association of country leaders from the sawing and drilling industry took the first step, of what was to become, a twelve year journey. So it is appropriate to ask, what has been accomplished, and how will the next twelve years be different than the first? The original purpose of the association was quite lofty. The founding delegates set forth goals such as facilitating the exchange of information between associations, international representation of the sawing and drilling industry with governments, unions and other organizations, training and professional development of sawing and drilling contractors, advancing the technical development of the trade and joint publicity and promotion. How has IACDS done in meeting these goals set over a decade ago? Even though delegates meet only once a year, a very close relationship has developed among members, professionally and personally, so networking and the exchange of information between association members on an international level has certainly been accomplished. IACDS has had success with international standards that will have impact on the industry for quite sometime. Development of the Tolerance Rule and the Basic Machine Parameters documents will increase professional development of the industry and influence international entities. Both documents are available on the IACDS website at www.iacds.org. Attempts have been made to coordinate the training programs of the different country associations, but have

met with limited success due, in part to a language barrier. More importantly, however, a wide variety of training programs are already being developed and offered by the countries themselvesprograms that adhere better to local governmental requirements. Two new projects, one to create a database of sawing and drilling photos and the second, to educate specifiers about sawing and drilling jobs via the web site are underway. The future is wide open and the delegates and industry representatives must step forward to decide what new projects IACDS should address for the benefit of members and the industry. The IACDS meeting was scheduled to coincide with Bauma and the presentation of the Diamond Award 2007 winners. IACDS and the German Fachverband Betonbohren und-Sagen presented the Gold Diamond Award to the Japanese company, Komu Co. The Silver Diamond Award was presented to the Italian company, Tondin and the Bronze Diamond Award was presented to the German company, Angerer. Twenty-five entries were submitted from Australia, Austria, Germany, Italy, Japan, Russia and the United Kingdom. The entries were judged using criteria which included the planning and complexity of the job, innovation, the degree of difficulty in executing the job and specific quality requirements. This is yet another example of the international cooperation that was fostered by founders of IACDS twelve years ago. Let us hope that the next twelve years will see even more international cooperation and advancement of the global sawing and drilling industry. The next formal step in this process will occur during the 2008 IACDS Meeting in Valencia, Spain on 2-5 May.

Best regards Patrick O’Brien President IACDS

Ingersoll Rand explores possible sale of Bobcat

Husqvarna acquires Soff-Cut, a US producer of concrete saws Husqvarna has acquired Soff-Cut International Inc., based in Corona, California. Soff-Cut is the leading producer of concrete saws for early entry concrete sawing. This technology enables concrete to be cut before it is fully set, which minimizes the risk of random cracking and also simplifies the working process in comparison with conventional sawing. In 2006 Soff-Cut reported sales of approximately USD 35.4 million (approximately SEK 240m) and had about 70 employees. The majority of sales

Ingersoll-Rand Company Ltd is exploring strategic alternatives for its Bobcat and construction-related businesses, including the Utility Equipment and Attachments businesses. The company’s alternatives may include an outright sale of the businesses or a spin-off to shareholders. For full-year 2006 these businesses collectively generated approximately $2.6 billion in revenues. The company expects to conclude the process in the second half of 2007. ”Our Bobcat, Utility Equipment and Attachments businesses represent world-class operations with exceptional people, products and brands; however, these businesses no longer fit Ingersoll Rand’s long-term strategy,” said, chairman, president and chief executive officer Herbert L. Henkel.

Q&A: Tom Stowell, New CSDA President Tom Stowell, a market consultant with Norton Penhall Diamond Products, based in Fullerton, California, was introduced as the 27th president of the Concrete Sawing and Drilling Association at the organization’s annual convention in Hawaii last February. Stowell brings more than 30 year’s of industry experience and CSDA involvement to the position at a time when contractors and manufacturers alike face a host of new and complicated issues. PDi’s Jim Parsons recently talked with Stowell about the industry’s challenges, opportunities and its prospects for the future.

Parsons: What is the overall state of the concrete sawing and drilling industry in the U.S.? Stowell: I see the industry as being very positive. A lot of it is due to the overall health of the economy. But I’m also seeing increasing capabilities and innovation on the part of our contractors. There are a lot of excellent problem solvers in our industry. That’s why they’re called ”professionals.” Equipment and diamond tool suppliers have contributed as well by working with contractors on ways to improve efficiency and capabilities. As a result, the industry has grown and become very competitive in the process.

Stowell: This was a big topic of discussion at our February convention. Employers need to understand that this generation’s expectations are far different from those of their parents. Individuals are no longer tantalized by the value of future rewards. They want to see those benefits now, whether it’s a more flexible schedule or greater learning opportunities. The trade-off is that given the right tools and incentives, these individuals are also incredibly productive. So while we don’t have to bend to their every expectation, we need to see things from their perspective. Recognizing this fact is the only way to be successful in recruiting and retaining these employees, because it’s not going to change.

Parsons: Growth and competition sound good, but is there a downside as well?

Parsons: How can equipment manufacturers help address these needs?

Stowell: As any industry knows, competition also causes prices to fall, making profit management more important than ever. Again, that’s where equipment and diamond tool manufacturers are playing a role. They continually develop and incorporate features aimed at helping contractors improve their operational efficiency, whether it’s making the equipment easier to use and maintain, or improving its ruggedness and life expectancy.

Stowell: They’re already contributing through improvements aimed at making products safer and more comfortable to use. Protecting operators is always a priority and the industry is examining it from any number of ways. For example, a programme at the University of Toledo is studying insulation options to protect operators in the event they inadvertently strike an underground conduit. And as we all know, concrete sawing and drilling is not a comfortable occupation. Manufacturers have come up with small ergonomic changes to handles and other features that reduce stress on operators. This is particularly important because contractors often look to their operators for recommendations on equipment purchases. No one will recommend anything that’s not comfortable to use.

Parsons: What other issues and challenges does the industry face? Stowell: The environment is always in play. Contractors are facing increasing responsibility for site cleanup. But I’ve always felt that our industry has been proactive in fulfilling these requirements. Safety and training are two other ongoing priorities. At this year’s World of Concrete, CSDA debuted the first product of our alliance with the Occupational Safety & Health Administration and the Highway Work Zone Safety Checklist, to complement our existing safety manuals and instructional programmes. More materials are on the way that will help contractors foster safe work environments and advance their professional training programmes. We’re also expanding our ”101” series of entry-level training programmes with disciplines, such as wall sawing and online training.

PDi • ISSUE 1 - FEB. - MARCH 2007

Parsons: The U.S. construction industry as a whole is also facing a serious labour shortage. What are the implications for cutting and drilling contractors?

Parsons: Do you have any specific goals during your twoyear term as CSDA president? Stowell: There are three things I’d like to see accomplished. One is to expand our Operator Certification programme so that entire companies can be certified. We’re currently studying the feasibility of such a programme. Another goal is to boost membership, which is an ongoing issue for any professional association. Our growth has been steady, but I’d really like to see it increase and improve our retention. Perhaps most important, I want to see us increase awareness of sawing and drilling among specifiers, architects, engineers and general contractors. Our industry offers many cost-effective benefits that these groups may not be aware of when formulating new projects. Having a ”champion” who can effectively convey these advantages in a variety of forums will generate more interest in sawing and drilling services. Parsons: What trends should concrete sawing and drilling operators watch closely in the coming months? Stowell: We’re encouraging contractors to get involved in local politics and issues that affect and influence their businesses and, more importantly, their clients’ operations. This has long been an industry where instinct and experience was pretty much all a contractor needed to remain competitive. Those qualities are still important, of course, but many of today’s business dynamics are bringing us into new, uncharted territory. Everyone needs to take the time to look beyond their respective day-to-day operations, see what else is happening in their communities and understand how it relates to the regional and national construction industry. I don’t see it as another management burden, but rather an essential component to your company’s future growth and success.

New skid-steer loader from Bobcat The new S100 skid-steer loader from Bobcat is a compact, limited weight skid-steer loader that can work in tight spaces and is easy to transport. Weighing just 1.8 t the S100 offers a rated operating capacity of 453 kg and a tipping load of 907 kg. Compact dimensions allow the S100 to manoeuvre efficiently in confined spaces. The low operating weight ensures that the S100 can be easily transported on a trailer or small truck from one job site to another. High engine power and hydraulic flow provide for extra fast cycle times and high productivity. Auxiliary hydraulic flow of 50 l/min provides power for operating over 30 different attachments. The attachment capability makes it an ideal machine for a variety of applications. The S100 is equipped with a new fullcomfort cab. The advanced electronic controls and instrumentation on the S100 provide the operator with a new level of diagnostic capability and control. The instrument panels and gauges are placed in the top left hand and top

right hand corners at the front of the cab. As well as a heated cab, there is a wide range of other options for the S100. The optional Power Bob-Tach system helps to speed up the process for changing attachments, simply by pressing a switch inside the cab. Another option is a bucket-positioning valve, which helps to ensure that the bucket and contents stay level. Thanks to the large swing open tailgate and transverse-mounted engine, the new S100 offers convenient one side servicing. Hydraulic and hydrostatic components under the operator cab can be accessed quickly. As in all Bobcat skid-steer loaders, the S100 offers the advantages of the unique ’bowtie’ drive chain design, using pre-stressed, heavy-duty drive chains in two short continuous loops on each side of the loader. No periodic, time-consuming adjustments are needed. The axle bearings are self-lubricated and never need additional greasing. The unique hub design also offers total seal protection.

New quick coupler for Bobcat excavators Bobcat has worked closely with Klac Industrie of France to develop a new quick coupler for fitting attachments to the Bobcat mini-excavator range. The quick coupler meets an increasing trend in Europe to use mini-excavators as tool-carriers and is one of three different quick coupler systems now available for use on the Bobcat mini-excavator range. The Klac-type coupler is available in four sizes

for all Bobcat mini-excavators from the 319 up to the 442 model. The new compact coupler retains the original geometry of the pin-on buckets for optimum performance and to provide an equivalent breakout force to the pin-on system. One of the key advantages of the new quick coupler is that it is wear compensating. Both the mobile locking plate and the fixed anvil have a matching tapered surface that works as a wear-

Weyhausen and Deutz develop hybrid loader Weyhausen’s AR65 prototype is said to be the first construction machine of its kind to feature hybrid power that combines a diesel engine with an electric motor system. Developed by Deutz in conjunction with electronics manufacturer Heinzmann and loader maker Weyhausen, the hybrid machine is said to offer the potential to reduce fuel consumption by up to 20%, while offering a power boost facility that generates up to an additional 30kW on demand. “The standard AR65 loader is powered by a 51.3kW Deutz diesel engine, whereas the hybrid version needs just a 36.9kW engine,” says Weyhausen’s Holger Wagner. ”The hybrid power boost is automatic, and cuts in when it senses additional load on the machine - without intervention from the operator.” Unlikely to reach commercial production until 2010, the system uses a four-cylinder, air-

cooled non-turbo engine with an integral motor-generator, installed where the engine’s flywheel would normally reside. Constantly energised when the engine is running, the system creates electrical energy that is stored within a lithium ion battery pack when asked to operate as a generator. In response to high engine loads, the system reverses its operating mode and turns into an electric motor. Doing so enables the system to supplement diesel engine power by taking stored battery power to assist the engine in driving the machine’s hydrostatic transmission. The firm says the electrical section provides a nominal 10kW output, with a peak capacity of up to 30kW, almost doubling the power of the four-cylinder engine.

Surprise move from Volvo In a surprise move Volvo has bought Ingersoll Rand’s road development division for a sum of US$1.3 billion. This acquisition leapfrogs Volvo into a leading position in the market for road construction machinery. Ingersoll Rand’s paving machines number amongst the world’s market leading brands and the compactors are amongst the market leaders in the US. Ingersoll Rand recently re-entered the milling machine market with a new line of machines. Volvo is a major player in the earthmoving equipment market and this move into the road machinery sector is entirely complementary. Volvo’s purchase comes at a time of intense competition and consolidation in the road

equipment sector. Atlas Copco recently bought fellow Swedish Dynapac for example. There had previously been considerable industry speculation that Volvo was in the running to buy Dynapac. Volvo is in strong financial shape and has been open about its intention to buy other businesses. With the acquisition of Ingersoll Rand’s road machinery range, this gives Volvo additional product lines. Volvo is not the first earthmoving equipment manufacturer to broaden its range into road machinery though as Caterpillar first took this route some years ago.

compensating system. When the coupler is closed against the bucket, it is centred by two surfaces machined in a ’V’ or wedge shape. The wearcompensating system eliminates any free play in the system. Two polyurethane bumpers act as a compression spring to apply pressure on the locking plate to ensure a secure coupling. Complete safety is ensured at all times, even if both springs are broken. Another safety feature is that unhooking, as well as hooking up, always occurs in two stages. Thanks to the pivots built into the coupler, the bucket can be picked up easily from the ground. The bucket is automatically cent-

red and the mounting hooks are locked gradually when the coupler is closed, preventing accidental unlocking. A special unlocking tool makes it easy to release the bucket. The tool is supplied standard with every coupler. Once released, the bucket remains safely suspended from the pivot of the coupler. The new Klac-type system complements the Bobcat X-Change system, the first quick coupler system for mini-excavators in the USA, and the Lehnhoff system, the market leader in Germany.

Olvex “Long-Reach” Plans Olvex is Russia’s biggest concrete sawing and drilling contractor and also very big in European terms with around 365 employees. The company’s target is for further expansion and for a few years now demolition and recycling has also been part of their services.

Complex concrete sawing and drilling and dismatling project has become a speciality for Olvex, like this one in the heart of Moscow.

PDi Magazine recently featured Russia in a country focus as it is experiencing tremendous growth with no signs of recession. We published a case story on a large controlled demolition job in Moscow by Russia’s biggest concrete cutting contractor Olvex and now take a closer look at the company’s activities.

Started with offering bitumen roofing systems Olvex is based in St Petersburg and was founded in February 1993 by N. Mokin and Sergey N. Chavkin, who now hold the positions of Chairman and General Director respectively. Both owners have known each other since their student days at the St. Petersburg State Polytechnic University in the 1980s and after the reformation of the country saw a potential in setting up a business together in the construction industry. Today concrete sawing and drilling is the dominant service in the company. The demolition and recycling services are increasing, but Olvex started out with offering bitumen roofing systems, and the company still keeps a department, which now provides its customers with up-to-date PVC membrane roofing systems. During the first year Mokin and Chavkin where the only employees but within 12 months the number had increased to 10. “In the times of Perestroika new technologies reached our country and the idea of using the most advanced equipment in our contracting firm in order to offer something new and more efficient, compared to old Russian methods, was, and still remains, very appealing to us,” says Yury Mokin. “Toward this end, we invested in an 8 t truck with a very sophisticated pumping system that pumped bitumen mastic up on a building’s roof, thus allowing for a higher rate of rooflaying. At that time, it was considered to be the latest roofing technique in Russia. Being on a constant lookout for new technologies, we soon came across concrete sawing and drilling. When required to remove an old multilayer roof on one job, we were tipped to use a Cedima CF15 flat saw, which easily did the trick. This was our first contact with concrete cutting equipment.” The German manufacturer Cedima was, besides Hilti and Tyrolit, one of the first to enter the Russian market and it was Cedima’s management, in the presence of D. Wirthgen and V. Rudolf, as well as the company manager responsible for sales to the CIS and Baltic states, Alexander Redich, that helped Olvex get a good start in this business. The start for Olvex as a concrete cutting contractor came in 1994, when it undertook a job to drill holes in the foundation of the famous Hermitage in St Petersburg to further strengthen and reinforce it. This was a very prestigious job for the company, which later led to several other big concrete cutting projects.

Survived the recession in 1998 In 1998 Russia was rocked by a dramatic economical crisis, also known as the 1998 default, which forced many construction companies into bankruptcy. But by then Olvex already had the economic stability to survive, which contributed to the company’s success. The 1998 default was a severe experience, which resulted in welding the Olvex team into a formidable unit. All the companies, which went through this economic ordeal and came out winners, now

When the hard times were over, the company further burnished its reputation by successfully completing several significant jobs. Among them was the large reconstruction and construction programme of power-generating unit No3 at one of Russia’s largest nuclear plants, Kalininskaya Power Plant located in Tverskaya oblast, where Olvex cored over 60,000 holes and sawed some 15,000 m2 of concrete. The company development received another boost in late 2004 when, at the initiative of Sergey Chavkin, Olvex decided to include demolition and recycling in its service package. “In 2006 we doubled both the turnover and the personnel of the demolition department on the back of a few big concrete cutting and demolition jobs, compared to the 2005 figures,” says Chavkin.

ness and we are growing very fast in terms of turnover and equipment. In 2006, our turnover from demolition operations was US$ 6 million and by June 2007 we already reached this level. I think we have every chance to double it this year,” says Chavkin.

Third and fourth quarter busiest

Demolition, a fairly new service Professional concrete cutting techniques appeared at the start of the 1990s in Russia and since then a large number of concrete cutting contractors have been established. But for the demolition the picture is different as there are just a few companies operating, the biggest being Satori. “Despite the fact that we are still young in the demolition and recycling business, with just three years under our belt, we have managed to gain substantial expertise in the busi-

Heavy duty demolition, often with high reach machines, and recycling is a young but fast growing sector within Olvex.

PDi • ISSUE 3 - JUNE - AUGUST 2007

Olvex’s key customers are large construction and building companies, government institutions and organizations as well as metallurgical plants, steel mills and nuclear power plants. Sometimes jobs are also done in co-operation with other demolition and concrete cutters, like the demolition of the Moscow hotel Intourist and the “Moscow-city” project, where Olvex helped the company Satori. Even though there is a lot of construction going on in the housing development and the business sectors, the lion’s share of contracts comes to Olvex from the metallurgical and power industries. Mokin says that most of the jobs start in the third and the fourth quarter of the year and right now Olvex are booked up for many months.

Massive equipment park Olvex demolition and recycling division has 10 demolition excavators from Hitachi, Cat and Volvo, some of them equipped with long front booms up to 20 m. The Caterpillar machines are the most popular among the operators but there are regions and areas in Russia where back up and service support are not readily available. Hitachi, on the other hand, has an excellent after market service in most Russian regions, according to Chavkin. The demolition attachments used by Olvex are mostly Verachtert, Krupp, Atlas Copco, NPK and Okada. In addition Olvex has three mobile recycling crushers and one stationary crusher and is about to purchase another mobile unit. Such recycling capacities along with the

strong presence in the regions make Olvex one of the major players in the demolition and recycling market in Russia. In terms of concrete cutting equipment the Cedima brand is dominant. Olvex has about 60 wall sawing systems and some 80% of them are Cedima. There rest come from Hilti, Hydrostress and Braun. The company also has around 100 drilling systems. Again Cedima dominates with 90% and the remainder are from Hilti. The wire saws are mostly wall saws that are converted in to wire saws, but Olvex has 15 regular Cedima CSA 1001 wire saws. The diamond tools come from Hilti, Cedima, Adel and Ehwa Diamond. Each year Olvex spends about US$ 3 million on tools and a further US$ 1 million on new equipment. Of the 365 staff in the company, 200 are highly trained professional concrete cutters.

When visting and writing about St Petersburg, the cultural capitol of Russia, it is hard to not mention and show its beaty. Below some characteristic photos from St Petersburg.

Continuous growth The future looks good for Olvex and everybody is very optimistic, even though the company is used to quick changes in workload. The outcome of the coming election could interfere radically with the development of the country. Chavkin believes that there is a potential for further growth in the company’s cutting activities but it is less than that of the demolition division. “Speaking about the demolition side, I am certain we can double our turnover in each of the coming two years,” says Chavkin. Olvex has its head office in St Petersburg with eight regional offices spread out over the country including one in Moscow. Jobs are carried out all over the country, but the majority of the work is in the big cities and in particular Moscow and St Petersburg. But there is now a trend towards more projects in other large cities, which is perhaps proof that Russia’s expansion no longer includes just Moscow and St Petersburg. In 2006, the turnover reached above US$ 22 million and the aggregate growth for 2007 is expected to be around 30%. The strategy for the coming two to three years is to grow domestically but also to find new markets outside Russia. Since 2005, the company has been operating successfully in Ukraine where Olvex operators sawed a few thousand square metres of concrete at various sites. Scandinavia, East Europe and the Baltic States are also of particular interest. In 2007, the company began to offer its concrete sawing services in Finland and Bulgaria where Olvex set up its

representation. The vast experience, which the company has accumulated in the field of concrete wire sawing and its reputation and expertise are beginning to attract a lot of interest from the Finnish and Bulgarian customers. In February 2008, Olvex will celebrate its 15th anniversary with a big party. There is little doubt that there will be new announcements to be made there. “The progress of the company has been, and remains, very much dependent on the stability that President Putin and the government have created in the country. The person that will replace Putin needs to carry on his work in order to maintain the stability,” says Mokin.

A New Crushing Italian manufacturer SIMEX has introduced the new CB line of crushing buckets equipped with a rotating crushing mechanism.

The new laser welding robots at Simex plant in San Giovanni in Perciceto.

SIMEX S.R.L IN SAN GIOVANNI IN PERCICETO outside Bologna manufactures a large variety of attachments for roadwork, construction, demolition and recycling. The product range contains a dozen of models that can be ordered in hundreds of different variants. The base models are divided into snow blowers, chain trenchers, wheel excavator cutters, vibratory wheel compactors, asphalt floaters, self levelling planers, cold planers, double drum rotary cutters and crushing buckets.

The new CB-line

and CB 2000 were launched in May and CB 2500 and CB 3500 in June. The remaining three models, CB 800, 950 and 1100, will be launched during this autumn. The product name represents the weight of the bucket in kg with full load. The crushing bucket has a direct drive and is connected to the hydraulic system of the carrier. If the bucket stops the bucket is manually reversed. “The first line of crushing buckets are developed for wheel loaders and skid steers but we don’t see any difficulties with developing larger buckets for excavators in the future,” says SIMEX founder and owner Micro Risi. According to Mr Risi the CR line is optimal for contractors needing to crush and recycle smaller volumes of debris. For instance on a demolition site the rubble is crushed and recycled directly on the site and can be used as new filling material. All material besides hard rock can be crushed in the CR line and to some extent even moist material with. Steel rebar is handled without any problem.

SIMEX has expanded its operations into producing crushing buckets, which were shown for the first time at the exhibition SAIE in 2006. The new SIMEX CB line of crushing buckets, contain nine different models in sizes from 1.4 to 2.4 m in width, bucket weights from 800 to 3500 kg and crushing sizes on the material from 10 mm to 80 mm. They are suitable for use on wheel loaders and skid steers. What makes the SIMEX crushing buckets different from other brands is the rotating function instead of jaw crushing. As in all other SIMEX products the main details and the functions Quality and technical are patented.

THE CONCRETE CUTTING, DEMOLITION AND RECYCLING of building materials continues to have high growth, which stimulates the market for demolition and concrete cutting tools and machines. The trend looks very promising with many small and big tool and machine manufacturers for demolition, concrete cutting and sawing and recycling launching new products and services and presenting record volumes and profits.

New tools to break, crush and pulverise

Furukawa Rock Drill’s new F22 and F45 weigh 1.6 - 3.1 t and are designed for excavators from 16 to 50 t.

NPK presented the new GH-series of hydraulic hammers, which replaces the E-series and has more durability, improved brackets for less noise and easier maintenance.

In the hydraulic breaker business, Furukawa Rock Drill (FRD) continues to be an active player in the European market and presented two “Second-Generation” large FSeries hydraulic breakers; the F22 and F45 weighing 1.6 t 3.1t and are designed for use with excavators from 16 to 50 t. By optimizing materials, and with a new hardening method, the new breakers have the same weight but higher performance than their predecessors. A completely new shock-absorption system minimizes transfer of vibration to the base machine, considerably reducing loads for the operator. The equipment is fitted with a breaker piston lift adjustment, which optimally adjusts the number of strokes according to specification of the base machine. Thanks to a newly developed breaker guiding system in the casing and rubber gaskets in the bores, an extra noise reduction of 6 dBA has been achieved. FRD also introduced the new VX crusher series at Bauma by showing the model VX225. This series is the first to be constructed completely of cast steel, which is possible due to a new hardening system and improved processing, resulting in higher performance at a lower weight. With an operating weight of 2.25t and a jaw opening of 1.1m, the VX225 is suitable for high-reach excavators. The breaking power of 1663/1051 kN and cutting power of 3402 kN, makes the equipment suitable for high speed recycling of concrete. The crusher can rotate 360° with an internally toothed ball rotation system. Atlas Copco wants to secure its place as the world’s leading manufacturer of large hydraulic breakers and launched a new giant at Bauma the Atlas Copco HB 10000 weighing 10 t. According to Atlas Copco the new HB 10000 has up to 50% higher productivity and represents a major step towards the creation of a new market segment. The company believes the use of hydraulic breakers as cost-efficient production machines for primary breaking could be considered as an alternative to drilling and blasting. The HB 10000 has all the well-known

technical features developed by Atlas Copco for its hydraulic breakers. A key factor for the high productivity is the Atlas Copco ProCare proactive service and availability concept, which guarantees dependable production. Another Japanese manufacturer of hydraulic equipment, Nippon Pneumatic Manufacturing Co Ltd (NPK), presented the new GH-series of hydraulic hammers, which replaces the E-series and has more durability, improved brackets for less noise and easier maintenance. There are 18 models in the new GH-series for carriers from 0.5 to 110 t. They all have a new range of brackets that reduces sound and vibration. The models from GH-7 for 12-21 t carriers are equipped with shock absorbing mounting brackets with special heavy-duty rubber mounts to absorb shock and recoil and impulse vibration. This reduces wear and improves operator comfort. NPK also introduced the new U-series of crushing PDi’s Romano Ferrario together with cruncher with one big centre tooth and a cenVTN Europe’s President Antonio tre cutter.

Another new NPK product was the SG110 sorting grab that has been developed for sorting, loading, replacing and deconstruction of light structures. It is also ideal for placement of heavy rocks and stones. The French attachment manufacturer, Arden Equipment, launched a new universal processor CU350 - CB with concrete shear for excavators in the range of 3.5 to 7 t. The attachment has a top plate for bolt on bracket. The jaws are made of 450 HB steel with rebar cutters. Arden is also testing the CU350 with aluminium jaws to further reduce weight. Arden Equipment also showed upgrades One of the new concrete crushers to their shears and range of sorting grabs.

The sorting grab has a new design with a different type of shells as well as the whole body. It is similar to S800 but 20% more powerful. Ingersoll Rand showed for the first time the newly formed Attachment Group with a full and expanded range of demolition and recycling attachments. These included the new Montabert V2500 heavy range hydraulic breakers for carriers from 27 to 40 t. This new breaker is specifically designed for demolition and constructions users who do not require full BRV technology. It provides high energy per blow and low frequency. The blow frequency varies from a minimum of 350 to a maximum of 500 blows per minute. The Montabert V2500 breaker has an The Finmac stand, one of the busiest automatic two stroke operating system that booths at Bauma. combines the main energy production stroke 22 PDi • ISSUE 3 - JUNE - AUGUST 2007

with a patented blank firing protection system, that give a signal to the operator as soon as the piston stroke exceeds 3 mm. Ingersoll Rand also continues to develop the Silver Clip range of hydraulic breakers with a new SC-6 and SC50 model. Other Ingersoll Rand products were the four RBU rotating pulverizers with 360° hydraulic rotation for carriers from 10 to 40 t for both primary and secondary demolition applications. There was also the three FPU fixed A new crusher for light carriers from Socomec.

pulverizers from 1.1 to 2.4 t for carriers from 12 to 35 t and the 10 HGR handling grapples for sorting and moving demolition rubble for carriers from 3 to 65 t. Dutch demolition and recycling attachment manufacturer Demarec was proud to show five new products at Bauma. In addition to the existing range of Multi-Quick Processors, Demarec launched the MQP-25. Depending on the installed type of jaw this new MQP weighs approximately 2 t, making it suitable for 18-25 t excavators. A prototype of the T-30 jaw especially developed for cutting tanks and plate materials wre shown, in combination with the MQP-30, which is suitable for 22-35 t. This was complemented by the U-45 jaw for universal application with the MPQ-45 on concrete with reinforcing steel. The DemaDrive System is a new range of maintenance free demolition and sorting grabs from The new Montabert V2500 heavy range hydraulic breakers for carriers from 27 to 40 t.

Demarec. The great innovation for these grabs is that they are based on the revolutionary patented DemaDrive-System. A fully closed system, with the shells mounted directly on four axle stubs that provide the opening and closing of the shells. The system has no cylinder and parallel bars (and consequently no greasing points) and is therefore completely maintenance-free. At Bauma Demarec showed among others three DemaDrive-System demolition and sorting grabs for mini and medium excavators and two for 12-18 ton excavators. These last two grabs are provided with a rotary ring with rotary motor and an oil leadthrough. With the DemaDrive-System Demarec presented a vision of the future at the Bauma 2007. Undoubtedly the technique will be Michele Vitulano showing the new fixed pulveriser IFP 400 launched at Bauma.

developed further for application on larger excavators up to approximately 30 t resulting in a revolution in the demolition and recycling industry. Demarec has also developed a new demolition and sorting grab DRG-65-DN, weighing 4.1t and suitable for excavators between 50 and 70 t. Demarec now has eight different types suitable for excavators, ranging from 12 to 50 t. Italian attachment manufacturer Trevi Benne has made several recent announcements, including the release of customized demolition and recycling tools. Customisation and a close relation with their clients is a major strategy for the Italian manufacturer. At Bauma Trevi Benne showed a new rotation solution containing two motors for the 360° rotation. The pulverizer MF40 had been equipped with the new reversed jaw solution, which completes the MF range. VTN Europe used Bauma to launch three completely new products, a new sorting grab, a pulverizer and a crushing bucket. Other news included a quick coupling with conical and hydraulically controlled locking bolts, which decrease the time for changing attachments as well as improving handling of the attachment. Tool change only takes a few seconds with the new quick coupler, according to VTN Europe President Antonio Vaccaro. Another Italian manufacturer Socomec recently attacked the market with a new range of attachments. For many years hydraulic breakers have been the only product offered by Socomec, but now the company also offers crushers, steel shears and sorting grabs. The company’s main news at Bauma was the introduction of the new silenced mono block hammer MDO 1000TS. Socomec has been quite successful in the USA. According to the US importer Roland Jarl, Socomec has doubled its sales in a couple of years and now has 23 distributors in the USA. Indeco, based in Bari, southern Italy, has introduced several new products during the last year and in particular focused on the new range of concrete crushers and pulverisers. At Bauma Indeco added a new fixed concrete pulveriser called IFP 400 for carriers between 5.5 to 16 t. Indeco’s President Michele Vitulano also said that the company had received a request from clients in the US to build a new giant breaker weighing about 12 t and with a tool diameter of 250 mm. Development has been going on for some time and the launch is scheduled for the US show Conexpo 2008. If this happens it will overtake Atlas Copco’s HB10000 breaker. There were two demolition robot manufacturers, Brokk and the new company Finmac Demolition at Bauma. Brokk shared their stand in the outside area with the German demolition attachment manufacturer Darda, which was acquired by Brokk last year. The Brokk and Darda combination has turned out to be an excellent match and for many years the two have developed their equipment in close cooperation. A Darda attachment is a guarantee for optimal output in combination with a Brokk and vice versa. Brokk also used Bauma to release the new small Brokk 50, which is replacing Brokk 40 and is the smallest demolition robot in the Brokk family. Originally introduced to strip down tiles in bathrooms, Brokk 50 is able to pass through 600 mm wide doorways. It can be transported in a standard passenger elevator or even climb up and down stairways. At the show the newly appointed Brokk President Per Waldemarsson was optimistic towards the future. “We have a very good set up right now and I am very optimistic. We have a complete range that with good margin meets the demands from our clients and the new Brokk 50 helped to complete that. Further the acquisition of Darda was an important step for us as Darda now is our specialised tool department devoted to develop the right tools for our The three pictures to the left showing the new Darda concrete crusher/shear CC 420 and the big news at the Brokk booth, the new Brokk 50.

The other demolition machine manufacturer Finmac Demolition Oy showed its new F16.Finmac is a small and young company and the range contains one model. The first machines will be delivered during the autumn and the priority is to set up a network of dealers in Europe and USA. The F16 was very welcomed and created a lot of interest among the demolition machine operators. ”I am completely amazed! I could in no way have imagined that the interest for our machine would be this big. In the evening each day I have no words left after talking constantly with clients during the day,” said Finmac President Paavo Salonen. “Even at the start on the first morning of the exhibition there was a line of people waiting to get facts about the F16. We have received several direct orders and tons of proposals from companies from all corners of the world that would like to be our distributors. When I go back to Finland I will need several days to go through all interesting enquiries.”

Diamond tools and concrete sawing and drilling equipment

Above two new products from Schwamborn.

Spanish manufacturer Solga Diamant released new products at Bauma. On the diamond tool side the company launched a new series of wall saw blades and a new core drill series. In addition the new drill system SDR 600, with drill stand also made its debut. Solga also showed a new compact convertible wall saw from Swiss manufacturer Demco. The wall saw, which also can be used as a wire saw, has been developed primarily for use with the Solga diamond tools. Solga Diamant has established itself on the world stage during the past decade and distribution is through dealers in 50 to 60 countries. The company has also been in a joint venture for many years with Sumitomo Group called Solgallied, which focuses on the manufacture and sales of diamond wire throughout the world. Countries where Solga has strong presence are Spain, Italy, Germany, Brazil, Russia, Sweden, Norway and Finland.

stration site. Tyrolit has extended its product range and divided into two groups for standard and premium users. Many new diamond tools were launched as well as flat saws, larger runway grinders and milling machines and new high cycle wall saw WX-15. Husqvarna Construction Equipment also displayed their extensive range of new diamond tools, wall saws, wire saws, drill machines and drilling stands, floor saws and power cutters. Hydro-Tec’s Tractive range of concrete cutting equipment was attracting considerable attention. Besides its line of high cycle equipment Tractive released a new compact high cycle wire saw 3P8 weighing less then 60 kg and offering a capacity of a big wire saw. Austrian EDT Eurodima, owned by the Rothenberger Group, used Bauma to launch their new image. EDT Eurodima introduced a new floor saw series Technical FS 450 as well as demonstrating their popular series of high cycle equipment. The Eurodima Tornado sb320 has received praise from users. Braun Machinenfabrik launched their new HF Titan wall saw that has a new grip and intelligent automatic control system. Titan weighs 38 kg with motor and drill head and has a cutting depth of 680 mm. Liechtenstein based Hilti introduced their new compact diamond drilling systems DD300 and DD500 that fit in the company’s well-known red toolbox. The new high cycle wall saw DS-TS 20-E was also on display as well as the new Combi hammer TE 40-AVR and new laser measurement equipment PD40/42 and PR25. US manufacturer ICS took the chance to show several newly released products. Among them the newest and lightest concrete chain saw ICS 603GC. The new 603GC from ICS is the lightest weight gas-powered, concrete cutting chainsaw on the market. Weighing less than 8 kg (18 lbs), this new saw will plunge cut to 250 mm (10 inches) and make square corners with no over-cuts. With a powerful, 64 cc, 4.2 hp engine and advanced, rear-port, multi-chamber air filtration the 603GC is dependable and powerful enough for a wide range of concrete and masonry cutting jobs.

Blastrac brought to Bauma several interesting product novelties for different kinds of concrete floor preparation. The product in the picture is the new floor grinder Blastrac BMG835 flanked by Blastrac President Brian S. MacKenzie and Blastrac Diamatic Product Manager Joop Müller and European Marketing Manager Jocelyn Sabatier.

The British supplier of diamond blades and core drills, Nimbus Diamond Products, continues its new-technology boost for its product range. At Bauma the company presented its new wall sawing blades with the second generation of the patented ”V-Max design” to increase cutting power and resistance in tough application with ”V” shaped segments that increase the points of attack by up to three. The sandwich segments protect side clearance and the segment height is 15 mm for longer life. The diamond section is only 9mm, which reduces side friction. The blades have the unique multi slots and expansion gullet design to accelerate the evacuation of slurry and cool down the blade. The centre part of the blade is made of copper to better absorb shocks to the diamond. The Belgian diamond tool manufacturer, Carbodiam, promoted its new products; the Sharkor drilling segments and the Alligator and Predator cutting blades. The patented Sharkor segments are used for drilling with a diameter from 50 to 1000 mm and have a unique geometry and increased diamond concentration without needing extra power. The patented alligator segments, with turbostart technology, ensure a very fast cut. This is partially achieved by reducing

PDi • ISSUE 3 - JUNE - AUGUST 2007

the frontal contact with the material. The blades have a diameter from 450 to 1200 mm and a segment height of 10 mm. The Predator blade has a unique geometric pattern for high-speed cutting on any type of construction material, reinforced concrete, granite and more. The special and patented drop shaped segments ensures a fine cut and a very high cutting speed. The diamond height is 11 mm and the blades are available in 125, 230, 300, 350 and 400 mm diameter.

Sandvik’s strategic move shakes up the industry In the ever-growing segment of trackmounted mobile crushing and screening units the strategic move by Sandvik Mining & Construction was by far the most notable event at this year’s Bauma show in Munich. By Heikki Harri

Fintec Crushing and Screening expanded their range of track-mounted crushing and screening units by Fintec 1440 that was Fintec’s first one equipped with an impact crusher. In the crushing side, Fintec now manufacturers units with jaw, cone and impact crushers. Fintec is the other manufacturer along with Extec that is now owned by Sandvik Mining and Construction.

Terex is undoubtedly the biggest manufacturer of track-mounted crushing and screening units in the world, since they have three separate companies in this field, namely Powerscreen, Pegson and Finlay. The photo shows a machine in the Powerscreen Horizon range of screens.

Sandvik announced that the company had acquired the entire businesses of Extec of England and Fintec of Northern Ireland, both important and growing manufacturers in the segment. Before Bauma, Sandvik owned 49% of Fintec and had no ownership in Extec. The move also indicated a clear continuation of Sandvik’s general strategy in recent years. Instead of waiting for organic growth the company acts quickly and acquires manufacturers in areas where they feel that they are not yet one of the leading companies in the respective industries. With these two acquisitions Sandvik overnight became one of the three leading companies in this segment. The other two are Powerscreen and Metso Minerals. According to industry analysts the three top companies now have a combined market share of approximately 80% in this very highly competitive business. Additionally there are close to 20 other notable manufacturers that now share the rest of the business and this congestion will probably result, sooner or later, in some withdrawals from the industry. To continue to compete, particularly with the big companies, the resources needed for product development and sales just might prove too difficult. However, there always seems to be a place for niche manufacturers that concentrate in special areas where the big companies do not have an interest.

Sandvik’s history in the tracked business

Particular screening boxes mounted on the conveyor are something new and so far introduced only by a few manufacturers. The Austrian Rockster is one of them.

Sandvik originally got involved in the track-mounted business in 2001 following Metso’s acquisition of Svedala. The EU authorities ordered Metso to divest some Svedala businesses, including track-mounted crushing and screening units. Consequently, Sandvik decided to acquire the business line. However, although Svedala had manufactured track-mounted units for quite a number of years, the company had not been a major player in the business, particularly not in a global sense. Sandvik soon realized the company had to invest more in the new business. The first action was to take a minority

PDi • ISSUE 3 - JUNE - AUGUST 2007

ownership in Fintec Crushing & Screening, which proved a very sensible move. The Svedala legacy included heavier machines, while Fintec complemented them in the lighter end of the range. Furthermore, Fintec became one of the biggest customers for Sandvik’s jaw, cone and impact crushers, and Sandvik’s sales network was also used to market the Fintec range and both parties benefited from the co-operation. However, the combined product offering still missed the middle size range, and this is where Extec proved a good choice. There were rumours in the market that Extec was to be sold by its owner, a British investor group, and there was initial industry speculation that the company would be sold to Astec Industries from the United States. For Astec, the Extec deal would have been next to perfect. American manufacturers of crushers and screens are only taking the first steps in the tracked business and the deal would have made Astec the leading American manufacturer of the segment. During Bauma Sandvik Mining and Construction president Mr Lars Josefsson explained the reasons for the acquisitions: “We see this business growing and if we can achieve our expectations, the acquisitions will result in considerable increase in business for Sandvik.” When details of the acquisitions were released, the regulatory process was estimated to take 30 days and the deals were closed on 31 May. The announcement at Bauma indicated that all three companies, Sandvik, Extec and Fintec would continue using their individual corporate identities. But at the end of May it was announced that the integration process would start immediately. It will be interesting to see what, if anything, will be announced at the Hillhead quarry show in England in late June, where the original plan was that all three companies would be on their separate stands with their own individual identities.

No real product news Almost all of the important manufacturers were present at

Bauma, displaying a mixture of new models and improvements to existing machines. One of the larger manufacturers, Metso Minerals, decided not to exhibit at this year’s Bauma. It remains to be seen how long the company plans to continue this policy. More recently, one of the real innovations in this segment was the Duplex-System designed by Rockster from Austria. The system provides the opportunity and option to change the crusher in the chassis. This is applicable between a jaw crusher and an impact crusher. Bauma naturally was a good place to promote the new concept, which had been launched prior to the show. Another recent innovation is the introduction of screening and separation boxes and devices mounted on the conveyor of the crushing unit.

Terex Terex is one of the fastest expanding manufacturers in the construction market. At the company’s press conference in Bauma, Terex CEO Mr Ron DeFeo emphasized that while the company’s growth a few years back was based on the result of acquisitions, the company is now growing organically. The growth rate is still one of the highest in the industry and no further acquisitions have been made in recent years. The crushing, screening and recycling related products from Terex were on display from the three separate Terex businesses of Powerscreen, Terex Pegson and Terex Finlay. The combined Terex product range was probably the largest in these market segments. Powerscreen machines at the show were Horizon 5163, Chieftain 1700, Chieftain 2100X and Finesmaster 120 Compact. It seems that Terex is still uncertain, at least to some degree, how the company wants to integrate and co-ordinate the three manufactures. Powerscreen obviously has a strong identity that it will be difficult to incorporate into an integrated Terex company. Rumours at Bauma implied that Terex Finlay will soon be integrated into Powerscreen.

Pilot Crushtec Pilot Crushtec from South Africa is probably the largest

manufacturer of track-mounted crushing units outside of Europe. The company’s TwisterTrac units, equipped with an impact crusher, have achieved several export sales. The company’s strength, in comparison to many European manufacturers, is their capacity to manufacture several types of crushers and other related equipment. The tracked business for Pilot Crushtec is still quite small, but expanding.

Hartl Powercrusher from Austria showed several new machines at Bauma. One of the particular Hartl features is an optical measuring belt scale system.

REV There are quite a few Italian manufacturers in this business. One of them at Bauma was REV, a 30 year old well established company in its home territory. REV has a large product range and displayed the GCV 60, the company’s latest model in its range of track-mounted primary crushers.

IACDS Annual Meeting and the Diamond Award 2007 A well appreciated and well attended annual IACDS meeting was held in Germany at the end of April. A couple of days earlier the Diamond Award ceremony took place at Bauma in Munich. Daniel Trachsel, Secretary of IACDS reports. Text: Daniel Trachsel, Secretary of IACDS Photo: Daniel Trachsel and PDi Magazine

The delegates of the International Association of Concrete Drillers and Sawers had their annual conference on 30 April after the Bauma construction fair in Munich, Germany. There were 33 delegates from 14 countries and four continents attending the meeting. But before that during and during the Bauma show according to tradition Diamond Award presentations were made.

The Diamond Award 2007 The ceremony took place at the IACDS and the national concrete drilling and sawing association’s booth behind a main entrance of the Bauma fair. Three out of 25 contributions to the Award from seven countries and three continents were given a prize for excellent and outstanding jobs in the concrete drilling and sawing field. The first prize was presented to Komu Ltd from Hiroshima, Japan. The second prize was awarded to Tondin S.R.L. from Gazzo, Italy, the winner of the 2004 Diamond Award. The third prize went to a company near Munich, Angerer GmbH from Garmisch-Partenkirchen, Germany. The German association successfully organized the Diamond Award 2007. The IACDS delegates decided to organize the next Diamond Award to coincide with the 2009 World of Concrete in Las Vegas, USA. Further awards will be held in conjunction with construction fairs around the world.

News from IACDS

IACDS president Patrick O’Brien from USA announced that the release of the second edition of the “Tolerance and Limits Standard for Concrete Drilling and Sawing” in 2006 had seen a remarkably wide acceptance among the specialized press all over the world. Intensive discussions finally lead to the release of the first edition of “basic parameters for machines” used in the concrete drilling and sawing field. A separate press release will be published soon, together with the publication of the standard. As parameters for machines and tools and many other definitions and prescriptions depend on national or international legislation, the delegates adopted a proposition to set up a working group within IACDS to observe and influence upcoming regulations in these fields. Alfred Landl, a delegate from Austria, presented a detailed outlook

to the world’s construction market, showing hot spots and cold spots of development to expect the next years. The countries reports of the delegates confirmed the differing economic outlooks. In a remote presentation coming from Edmonton, Canada, Greg Kureluk from ProTraining.com proved that employees could be trained via the Internet. The US-association CSDA has already introduced this new method of training with great success. It allows employees to learn essentials of their job at home on screen and their employers to have constant control over the progress of the training. The delegates adopted with great pleasure the application for membership of the new Spanish professional association AEDT, located in Madrid. During the meeting, IACDS’ officers supported and advised representatives from Russia in the building up of a Russian professional association.

Elections Patrick O’Brien was re-elected president for a new two-year term. The two Vice-presidents Norikazu Shibuya from Japan and Peter White from Great Britain support him. The 2007 annual meeting was perfectly organized by the German Association of Concrete Drillers and Sawers who also managed to win more than 20 sponsors to finance the meeting. The new Spanish Association AEDT invited the delegates to have their 2008 annual meeting in Valencia, Spain scheduled for 2-5 May 2008.

PollutionSucks! Dust busting has become a big issue in the last five years and mainly due to stronger legislation. It is not only professional dust extraction manufacturers that offer dust extraction solutions, but manufacturers of concrete cutting and floor preparation equipment are also offering their own tailor made products. Handling of general dust, hazardous particles impossible to spot for the human eye and concrete slurry from sawing and drilling has luckily become an issue also for manufacturers of equipment generating the waste material.

More tailor made OEM products Continuous investigations highlight the danger in working in areas with a high degree of dust. Construction workers are also the ones that are at highest risk of getting cancer or other types of lung deceases. Protective clothing, respiration masks and other similar equipment are not always enough protection and need to be combined with efficient dust extraction devices. Floor grinding is a contracting segment that generates a lot of dust and manufacturers did not use to focus on the containment of dust. But now that has changed as most of the Dry and wet vacs from Hilti.

bigger manufacturers offer dust extraction solutions. The biggest, HTC Sweden AB, has an extensive line of ten vacuums for dry material, two cyclones and one wet vacuum. The models are produced to HTC specifications and are thought to be made by a specialist manufacturer for HTC. This strategy is common for most of the larger floor grinding equipment suppliers. Scanmaskin, another Swedish manufacturer, offer five different models of dust extractors and marketed in the name of Scan Dust. Husqvarna King Concepts offer two models called Flow Max. Blastrac with Diamatic is probably the only one with its own production of dust extractors and offer three mobile units and one stationary industrial vacuum. At Bauma Blastrac launched a new model to go with their large floor grinders. The OEM production is common and there are several vacuum manufacturers around the world, but only a few producing professional industrial equipment. The biggest ones are Dustcontrol, Pullman Ermator, Ruwac, Nilfisk-Alto, Neder-

man, and Numatic. Hilti also make dust extractors, but is not their core business.

Qualified ceiling opening with a Tornado sb320 Early in 2007, Weigold Bau GmbH - Beton bohren Beton sägen from Glatten, Germany was awarded a contract to make a ceiling opening larger at a height of 7 m at Aldinger in Horb Neckar. The ceiling is a concrete construction with 550 mm joists and a 300 mm concrete ceiling. The restricted space and the 850 mm cutting depth were the main reasons to settle for the braxx wall saw tornado sb320. The EDT EURODIMA tornado sb320 is a high frequency electric wall saw with 32 kW maximum power at 63 A current. It is designed for a cutting depth of 900 mm with a diamond blade of 2 m diameter. When setting up the saw, the braxx control bc320 proved to be an easily manoeuvrable core of the unit, having a total weight of only 52 kg. By comparison a 30 kW less efficient hydraulic unit weighs at least 200 kg. The sawing started on 11 January 2007. A pre-cut was made with a 600 mm diameter diamond saw blade, equipped with the new EDT EURODIMA premium segment, WS42XP with 5 mm segment width. Then, a depth cut set was used, again with the segment type WS42XP with 800mm diame-

ter in 5 mm, 1,2 m diameter in 4.7 mm, 1,6 m diameter in 4.4 mm and 2 m diameter in 4.1 mm width. The machine achieved an average cutting rate of 10.5 m/minute with the 600 and 800 mm diameter saw blades. The cutting rate of 8.9 m/minute is an excellent value for the big saw blades. The 850 mm cutting depth meant a precise first cut had to be made with the smaller saw blade, otherwise, the in-cut start would not be possible due to the frictional resistance of the big saw blades. A total of 15 m of the concrete ceiling, weighing 5 t, were cut at the hole. That concrete was removed with an indoor crane and transported with a flatbed truck. The total cutting area was 8.5 m2. The tornado sb320 was in use on site until 18 January. Its cutting performance exceeded a comparable wall saw with hydraulic drive.

Husqvarna Construction Products launches Oilguard Oilguard is an optical indication system that prevents the Husqvarna power cutter, K 750, from operating and breaking down as a result of the user filling up the machine with pure gasoline. ”Oilguard is the latest result of our efforts to develop smart solutions that facilitate and make our customers’ and users’ work more efficient,” says Husqvarna Construction Products power cutters product manager Håkan Aldén. ”It is a well-known problem that users sometimes mistakenly fill the machine up with the wrong fuel and through that cause the cutter to break down. With Oilguard, that risk is eliminated.” The system functions so that a colouring substance detects whether pure gasoline is being used in the power cutter. If that is the case, the machine idles and cannot

be operated until gasoline with the right two-stroke oil is added. The Husqvarna power cutter K 750 was launched in 2005 and is a major seller to the rental market and to contractors with large machine fleets that include both two-stroke and four-stroke engines. ”Oilguard is an excellent function for this type of customer. In addition to saving money, it also eliminates any potential conflict between the company and the user as a result of a broken down power cutter. At the test launches, customers have been very positive,” says Håkan Aldén. The safety system can temporarily be deactivated, whereby the power cutter can also be operated with two-stroke oil other than Husqvarna’s. However, this can be detected by the machine.

First step taken towards a Russian Association At Bauma Russia took its first step towards forming an official concrete sawing and drilling association. A small number of Russian concrete cutters like the companies Akkem (Adel), Spezmontage and Olvex joined the meeting. Specially invited were also Pat Oâ&#x20AC;&#x2122;Brien, President for IACDS and Executive Director of CSDA, Daniel Trachsel, Secretary of IACDS, Horst Wappler, secretary of The German Concrete Sawing & Drilling Association, PDi Magazine Editor-in-Chief Jan Hermansson together with a number of suppliers like Tyrolit, ICS and Hilti. Russian concrete cutting industry is estimated to contain between 250 to 300 professional concrete cutting contractors. There are around 40 concrete cutters in Moscow and another 40 in St Petersburg. Up to five of these are considered really large while the rest have between 5 to 10 employees. It is also estimated that some 1000 drill systems and between 150 to 200 wall saws are sold in a year in Russia right now. The annual turn over for each contractor varies between EUR 350 000 to over EUR 10 000 000. The website of the Russian Concrete Sawing & Drilling Association can be found at www.rnccsd.ru.

The Russian contracting and manufacturing Adel Group is experiencing a boom time. The diamond tool sector and the contracting side are booming in Russia, keeping the company’s approximate 280 employees busy round the clock. 42

PDi • ISSUE

THE RUSSIAN DIAMOND TOOL and contracting industry is young, but European manufacturers like Hilti, Cedima, Tyrolit and Husqvarna have grown stronger since the reformation of the country. During the Soviet era both manufacturing and contracting were controlled by the regime and the strongest and only foreign manufacturer was Diamant Boart. But now it is a different story as Russia even has a few domestic manufacturers and Adel is far the biggest.

Three years of production But Adel has only been developing and producing diamond tools for three years. Originally Adel was a big sawing and drilling contractor with over 220 employees. The contracting division started in 1992 and was founded by Valery Borisov and Dmitry Klimashew. Adel is based in Russia’s “Silicon Valley” Selenograd just outside Moscow where they have manufacturing, stock and contracting operations. The contracting activities called Akkem is run by one of Akkem’s joint owners Kirill Lomonosov who together with Valery and Dmitri started in the business in 1995. Valery and Dmitry head the development and manufacturing respectively.

Funds to build up the country

Adel has had a flying start and production is going full speed. “The concrete cutting industry started before 1995 and at that time a lot of government funds were given to build up and 3 - JUNE - AUGUST 2007

renovate Moscow and St Petersburg and that went on for many years,” says Valery Borisov. “Today things are changing and our government has now also started to invest extensively in other parts of our country, which has increased the demand on tools, equipment and services. Besides general construction of apartment houses and business centres a lot of investment is in roads and airports. This is very positive for our tool production and so far we see just a continuous growth.”

The assortment Adel manufacture standard core bits from 24 up to 600 mm, blades from 400 mm to 3 m and saw blades for asphalt and green concrete. They also have an extensive line of customized diamond tools for specific requirements. The company also manufacture and sell all types of diamond segments to suppliers and end users as well as adapters, lengtheners, extensions and grinding washers. The company also re-tips blades and core bits for their Russian clients. The R & D and production facilities are modern and most of the manufacturing machines come from the German company Dr. Fritsch. Adel has 25 employees in production and another 20 engineers and executives.

Expected growth both at home and abroad The domestic market is the strongest and represents some 40 % of the production. With investment now moving out to other areas Adel is looking to expand into regions like Samara, Krasnajarski and Toliati. But Adel also has an extensive

Adel plans to set up an assembly plant in each of Russia’s 16 regions. Eight plants will be established this year and the rest over the next two to three years.

Production capacity Adel currently produces around 150,000 segments per month. This rate will be up to 200,000 by September and 250,000 by the end of the year. Valery Borisov believes they will have capacity in the future to produce up to 1.5 million segments per month. The production method contains cold and hot pressing machines. The blades and core bits are assembled automatically and quality tests are made regularly within the plant and in the field. The Selenograd plants have their own electricity generation station and a separate pipeline for gas that provide power to the plant. Adel also keeps a large stock in order to offer the best service with some 200,000 segments and around 60 t of blade steel and around 5,000 core bits. During the last couple of years the turnover of the diamond tool production has doubled and by the end of this year they are looking at a 30% increase. Together with the concrete cutting activities in Akkem they are estimating a 60% increase. The total turnover for the group will reach some EUR15 million by the end of 2007 with manufacturing representing some EUR 6 millions at the moment. The competition on premium class tools mostly comes from foreign manufacturers like Hilti, Cedima and Tyrolit and to some extent from another domestic manufacturer Kermet.

Our target is now to increase sales to Europe and we will begin with the eastern European countries like Poland, Czech Republic, Bulgaria, Croatia and Macedonia and then Germany and Austria. But in order to increase sales at home and abroad we have a detailed strategy for the coming years,” says Valery. In order to meet the demands on the domestic market

Now the company employs more than 7,800, including 370 designers and engineers, and is well-known for its chainsaws and other garden power tools in more than 160 countries. Stihl is probably less well-known for its cut-off machines that are also sold all over the world. In fact the company manufactures and sells five models of cut-off saws, which are the TS 410, TS 420, TS 460, TS 700 and TS 800 with power output between 3.2 to 5.0 kW and with cut-off saw cutting wheels with 300, 350 and 400 mm. With an engine power of 3.2 kW the two new cut-off machines, Stihl TS 410 with the 300 mm cutting wheel and TS 420 (350 mm) are built specifically to cope with the tough demands of cutting asphalt, stone and metal.

Stihl 2-mix technology and new filter system Both models have engines with Stihl 2-mix technology; a 2-stroke engine with upstream scavenging that considerably reduces the unavoidable scavenging losses with two-strokes that allow unburned fuel and air mixture to escape into the environment with the exhaust. This technology cuts both exhaust pollution and fuel consumption. Both TS 410 and 420 are equipped with a new filter system with a cyclone separator that increases service life and economic efficiency. This highly effective filter system already removes around 80% of the particles from the intake air in the first stage and returns them to the ambient air. Filter life is thus increased several times over compared with conventional systems. “For us it is important that it is easy and comfortable for the operator to handle the machines, and we have enhanced these machines with several new features,” says Horst Otterbach. Various components of the new Stihl cut-off machines, such as the guard, are made from magnesium. The result is a very low weight of only 9.4 kg and 9.6 kg, respectively in this power class. That and their compact construction make these two new machines very suitable for hand-held cutting. The loop handle, developed in accordance with the latest ergonomic findings, provides excellent ease of operation in any working position as well as optimum control of the machine while cutting. Transmission of engine vibrations to the user’s hands and arms is greatly reduced by a special anti-vibration system. That takes the load off the user’s muscles and joints as well as saving effort. At only 3.9 m/s the vibration value is perceptibly below

the limits according to the EU Directive on exposure of workers to vibrations (2002/44/EC). If longer cutting distances are involved or when precisely cut edges and exactly maintained cutting depths are required, the new cut-off machines can be operated with the STIHL FW 20 cart. This has a quick-action clamping system allowing the cut-off machine to be mounted quickly and easily without any need for tools or a conversion kit, along with convenient adjustment of the cutting depth. The STIHL TS 410 and TS 420 are supplied as standard with a water attachment and a composite resin cutting wheel of 300 mm and 350 mm respectively. “Our own diamond cutting wheels are available as accessories to make these machines compact and fit for universal use with high and long lasting performance,” says Horst Otterbach.

Bobcat launches Smallest 80 Series Breaker Bobcat has launched the new Bobcat HB280 hydraulic breaker, the smallest model in the company’s 80 Series. With a flow requirement of

15 l/min, the HB280 breaker is specifically designed for the 820 kg Bobcat 316 microexcavator, which has an auxiliary hydraulic flow of 20 l/min. The new breaker has a frame with a cylindrical design, providing improved access to jobs in confined areas such as inside structures or holes. The breaker is equipped as standard with a special shield to protect hoses and fittings from being damaged when working close to the ground or in tight spots. The internal design of the HB280 breaker involves fewer moving parts and no tie rods. The breaker can be completely disassembled in less than five minutes, without the need for special tooling. An automatic pressure regulator ensures the HB280 breaker operates at its optimal pressure to deliver a constant energy per blow. The HB280 breaker also incorporates very effective soundproofing, whereby the striking assembly is held top and bottom by a suspension system that is not in contact with the outer cylindrical housing. There is also a patented treated steel ring ’clip’ system, which retains the bushing of the tool and protects the greasing system. This ring is easily removed with a multi-purpose tool supplied with the breaker.

Ingersoll Rand Utility Equipment has launched the new IR20BV breaker, extending the company’s breaker range to five models, as well as a new handle assembly for this model and the existing IR25BV, IR30BV and IR40BV breakers in the range. With a weight of 20.8 kg, the new IR20BV breaker fills the gap between the current IR15BV and IR25BV models. The power output of the IR20BV breaker is 50 J, and it has an impact frequency of 1320 bpm. The IR20BV breaker offers two shank sizes of 25H x 108 and 28H x 160. The new handle assembly on the IR20BV, IR25BV, IR30BV and IR40BV breakers is again made of steel, but is lighter than the

previous handle body. This results in a weight reduction of about 1.3 kg per model and improves the balance of the breaker. The low weight of the three smaller breaker models, the IR15BV, the IR20BV and IR25BV, allows them to be handled and moved around easily. Moreover, with their high power to weight ratios, they offer high productivity in less demanding breaking applications. The high power of the larger IR30BV and IR40BV breakers is ideal for working on hard materials. Ingersoll Rand paving breakers meet a wide range of applications in demolition, road repair and building, equipment rental, construction, building, utility and industrial markets.

The transformer station was connected to the underground parking, it was not possible to remove it with an excavator. The contractor opted to dismantle the structure using diamond technology. The cutting works were awarded to Josef Seidl GmbH using the new EDT EURODIMA FS450 floor cutter, which, with its 3-cylinder Deutz turbo diesel engine, has a high-performance and torsionally strong drive motor. The operator appreciated the central operating console and the fully hydraulic steering enabled simple and fatigue-free movements of the floor cutter, as well as corrections during cutting. The concrete in Braunau is hard to work due to its high quartz content. This demands a great deal from the diamond tools and the machine and for this project EDT EURODIMA recommended a WS46X C3 diamond saw blade. The ceiling was 270 mm thick and reinforced about 2%. For treating the columns and supports

and not weakening them through unnecessary cuts, the FS450’s adjustable cutting depth limitation was especially helpful. This option, which can be adjusted easily via the steering electronics, allows a constant cutting depth. The operator particularly appreciated the high mobility and the quick conversion from right side to leftside cutting. There was occasional binding of the saw blade and the hydraulic v-belt tightener was very useful as it allowed the blade to be easily released. The floor cutter achieved chipping performance of 1150 cm3/min at a circumferential velocity of 58 m/s with the 800 mm diameter WS46X C3 diamond saw blade and segment width of 4.4 mm. Its quiet running and smooth feed control had a positive effect on the tool wear and the 121 m2 cut surface were achieved with two diamond saw blades.

Two new drill motors with smart solutions Husqvarna Construction Products’ new hand held DM 230 drill motor replaces the DM 225 and is designed for use by professional drillers, hire companies, construction contractors and users such as electricians and plumbers. The DM 230 is based on new electronics, which gives the machine increased reliability and a longer life. It has a patent-pending three-step, water-cooled gearbox, where water runs through the spindle shaft. Thanks to this extra cooling, wear and tear is reduced on the

gearbox and sealing. The DM 230 is based on modular construction incorporating gearbox, motor and handle, which facilitates maintenance and repairs. In addition the new electronic solutions give the user substantially better control over the drilling. There is Softstart, which regulates the increase in RPM and Elgard protects the electronic system against overloading. A Smartstart button provides lower RPM with retained high effect, which is useful at start-up and when drilling in

especially hard materials.

New DMS 160 Husqvarna has also launched the DMS 160 with three different variations of drill stands. It provides many drilling possibilities and is suitable for the hire market, contractors, professional drillers, and for users such as electricians and plumbers. The stand mounted DMS 160 has been developed using well-proven technology. The motor is double isolated, which makes the machine safer to use. Other technical refinements include the built-in safety clutch and the electronic load/power indicator, which causes power to

automatically be cut off during overload. This substantially increases the machine’s life and performance. Thanks to its low weight, it is comfortable to work with. The DMS 160 comes in three different versions: DMS 160 A (expandable base plate), DMS 160 AT (tilting and can be angled with quick connection between the column and the expandable base plate) and DMS 160 Gyro (stand with stanchion between floor and ceiling and with the same flexibility as other Husqvarna Gyros).

JCB excavator clears the way for warehouse development

One of a dozen JCB excavators bought by UK demolition company Squibb and Davies has been involved in flattening the site of a factory to make way for warehouses. The company has put a 22t JS220 to work on the Crown Aerosol site, in Oddicroft Lane, Sutton-in-Ashfield, Nottinghamshire. The London-based firm was contracted to carry out the work by Wilson Bowden Developments, which plans to create a range of industrial and distribution units on the land. The scheme has been dubbed ’Gateway 28’ due to its proximity to junction 28 of the M1 motorway, a factor which Wilson Bowden hopes will attract warehouse-based distributors to the site. More than 2,500 t of material has been cleared from the 12-acre site since Squibb and Davies started work in January. Of the 12 tracked excavators purchased by Squibb and Davies, six were JS220s. The company also invested in a pair of 33-t JS330s and four JS460s, at 46 t the largest machines in the JCB range.

The JS220s and JS330s are from JCB’s XD (extra duty) range, which is purpose-built for the demolition industry. Each machine features a reinforced boom and dipper, rugged undercarriage guarding and covers and cab protection. The JS460s were built to the same exacting XD specifications as the other machines and were also modified to meet Squibb and Davies’ requirements for tool and attachment installations.

Brokk’s machines demolish upscale mall in Jakarta Located at the heart of Jakarta’s financial district, Plaza Senayan offers a very classy shopping experience. This elegant mall features Metro Department Store, Sogo Department Store, Armani, Versace and many other high profile brands. Until recently, Plaza Senayan also offered a four storey, seven cinema Studio 21 Cineplex. In order to increase the retail space, the Cineplex was to be demolished. The main contractor for this project was the Japanese developer Kajima Corporation. Kajima had very strict restrictions on low noise, minimized vibrations and no exhaust fumes from diesel machines. If using manual labour, the project was expected to take 5 months. With such a long project time, the loss of revenues from retail tenants would be substantial. Technocrete Ptd. Ltd. proposed using the highefficiency but low-noise Brokk Demolition Brokk 180 with concrete crusher demolishing a flight of stairs at Plaza Senayan.

machines and was awarded the contract. Two units of Brokk 180 were used to complete this job. The result was a much faster completion of the project and a very satisfied customer. The project took only 75 days to complete compared to the initial estimate of 5 months. After using Brokk for over two years, the staff of Technocrete has come to depend on the highly productive and reliable Brokk machine. ”Our workers have become so used to these machines that they can’t work without them”, says Jimmy, the main sub-contractor for Technocrete Pte Ltd. ”This clearly shows the benefit of high efficiency machines even in low-cost countries like Indonesia”, says Jonas Stahlbage, Brokk’s Area Manager in AsiaPacific. ”Manual labour cannot compete with the speed of Brokk. We have seen similar developments in China and India where Brokk is becoming more and more popular for controlled demolition projects.”

UK company “Crush it” comes back for another Red Rhino The UK company, Crush It, based in Chesham, bought a Red Rhino 4000 series in November 2006 to hire in its local Buckinghamshire area and for its own cost reduction at its landscaping company. Used as an onsite recycling tool the Red Rhino 4000 saves the company huge amounts of money on skip hire, haulage and buying crushed aggregates. The company’s representative Peter Woolnough realised the potential of hiring a Red Rhino when he saw the demonstration of the crusher. ”The cost reduction and

recycling concept of the Red Rhino Crusher was my prime motivation for buying the 4000 series crusher,” said Peter. In the first 16 weeks the company benefited from a significant reduction in costs and from 22 days of hire income. The company said that three quarters of these days were the result of enquiries forwarded directly from Red Rhino. “The rate of hire enquiry has been so demanding that 10 weeks after buying the 4000 series I have ordered the 5000 series tool,” said Peter.

IACDS releases drilling and sawing parameter standard The delegates of the International Association of Concrete Drillers and Sawers (IACDS) finalized a new standard entitled ”Basic Parameters for Concrete Drilling and Sawing Equipment” at their annual conference on April 30, 2007 in Germany. For many years, contractors have been challenged by the almost impossible task of comparing machines for the concrete drilling and sawing industry. They realized that some manufacturers define the power of their products by indicating the input power, whereas others prefer to measure the power at the hydraulic unit or at the spindle of the tool. Contractors have thus been unable to compare machines offered by different manufacturers, as they are able to compare cars and trucks from different brands. On the other hand, respectable manufacturers also want to make their business in a market in which they know that a real comparison of their products is possible. These were the reasons why the IACDS delegates representing national associations from around the world, as well as manufacturers and contractors, decided to make a first step to develop uniform parameters describing concrete drilling and sawing machinery. The result is the release of the IACDS Standard 2007/1, ”Basic Parameters for Concrete Drilling and Sawing Equipment”. The standard is now available in English and German on the IACDS website www.iacds.org. In this edition, parameters are available for this wide range of machines: • Power packs (hydraulic units) • Wall saws and floor saws • Wire saws • Drill rigs • Electric drilling motors • Hydraulic drilling motors

For each type of machine specific parameters are defined and explained in examples. Almost 50 items are specified like: pump capacity of hydraulic units; input power P1, output power P2 at the spindle at rating mode S1 for electric motors; maximum drive torque at the drive wheel and starting torque of wire saw units; recommended drilling motors for drill rigs including maximum drive power. IACDS expects manufacturers to update their machine specifications within one year. The delegates have already decided to add additional parameters in future revisions for even better comparison of products coming from different companies.

CSDA Specifier’s Resource Guide Online Architects, engineers, general contractors and government officials—virtually everyone who is involved in specifying, sawing and drilling services in their daily work, now has 24/7 access to the CSDA Specifier’s Resource Guide online. CSDA originally offered this guide as a printed manual,

PDi • ISSUE 3 - JUNE - AUGUST 2007

but the guide is now offered free of charge online at the CSDA website at www.csda.org. “The mission of the Concrete Sawing and Drilling Association is to promote sawing and drilling services and the contractors that perform these services to specifiers highlighting the advantages in renovation or demolition projects,” said the association executive director Patrick O’Brien. “To make these resources available at any time on the Internet will help specifiers access this information when they need it, since the information is available on demand”. Diamond cutting systems can provide significant cost advantages over conventional removal methods and many architects, engineers, general contractors and government officials are not aware of the cutting techniques and capabilities. Whether it is a major project on the infrastructure such as a power plant or dam renovation or the repairing of a highway or airport runway, cutting and removing large sections of concrete can be much more cost effective than other demolition methods. It can also help maintain the structural integrity of these structures. The renovation and remodeling of existing commercial and residential buildings can offer unique challenges to architects and engineers when compared to new construction, but concrete cutting with precision diamond tools can offer reduced dirt, dust and debris, noise and vibration to tenants who may live or work in a building undergoing renovation. At the same time, new commercial construction can also be avoided as concrete cutting contractors can create openings in concrete floors and walls for electrical conduit and HVCAC instead of installing forms before the concrete pour. The Specifier’s Resource Guide contains a brief summary description of each cutting discipline as well as typical applications and specifications. An extensive list of reprints for each type of cutting are also available in the CSDA association’s official magazine Concrete Openings. The guide is organized by cutting technique such as core drilling, flat sawing, wall sawing, wire sawing and additional cutting methods (including hand and ring sawing, curb swing and grooving and grinding.) These job stories can help specifiers better understand the wide range of cutting capabilities that exist and provide ideas on how they can utilize the advantages of diamond cutting tools in future projects. In addition to the job stories with cutting applications from around the world, the Specifier’s Corner includes Standards, Specifications, Tolerances and Best Practices that have been developed by CSDA over the past few years to provide specifiers with documents that they can use when preparing project specifications. The materials have been written to exacting standards, therefore using them should make the job of a specifier easier. Whenever a specifier is writing specifications for any type of renovation or demolition project, it is the hope of the CSDA contractors that they will

visit the CSDA website to make use of the new Specifier’s Resource Guide or any of the other resources developed specifically for specifiers.

US Demolition Association elects new President Drew Lammers, president of Cincinnati’s King Wrecking Co., has been elected President of the National Demolition Association, the premier trade organization representing more than 1,000 firms in the United States and Canada involved in the demolition process. Coming onto the Executive Committee for the first time as Treasurer is Paul Conway of Nuprecon LP, in Snoqualmie, WA. Lammers has been active in nearly every committee and on the Association’s Executive Committee during his 12 years with the organization. Most recently he served as Vice President. Among his goals for the National Demolition Association is to increase membership, to educate First Responders about the skilled support that demolition companies can provide them, and to maintain the Association’s first-class safety programmes. He is also committed to furthering the relationship of the Association with Purdue University, which is the first university in the country to offer demolition as a specialization. Dave Loewendick, Jr., of S.G.. Loewendick & Sons, Grove City, OH, now holds the post of Past President. In addition to Conway moving into the Executive Committee as Treasurer, the Association has appointed a number of new members to its Board of Directors. They are: Scott Knightly, Enviro Vantage, Epping, NH; Kevin Mitchell, Greenspoon Specialty Contracting, Brampton, ON, Canada; John Lloyd, Lloyd’s Construction Services, Savage, MN; Christine Reed, Brandenburg Industrial Service Co., Chicago; Peter Banks, CEI Boston, East Walpole, MA; and Richard Lorenz, Central Environmental Services, Orlando, FL.
