PDi improves the worldwide coverage Dear readers By now and for those of us who live in the northern hemisphere, summer already feels distant. But in colder regions of the world the warm period of the year is the period when the building and construction sector is most active. This year it is more active then ever. The majority of the countries in Europe are still booming in terms of construction projects and the planning for future projects is also ongoing. The demolition, sawing and drilling contractors I have spoken to recently say that they are very optimistic about the future. There are no signs of recession, even though growth has slowed down in some parts of Europe. However, the USA is a different situation. I recently visited New York and judging from my experience the building and construction industry is booming. But everybody knows that New York does not speak for the whole country. This 100 year old city has its own life and constant need of renovation due to the wear caused by the 18 million people living in the New York area. I visited a worksite at the Juilliard School in the Lincoln Centre and report on this project on page 14 to 17. In addition we also have several interesting interviews, including one PDi’s Jim Parson made with Peter Bigwood and his colleagues at Atlas Copco Construction Tools in USA. We also have three different surveys. One is about the surface preparation and polishing industry, another about hydrodemolition and a third about new breakers. We are also publishing a pre-view on the Italian show SAIE 2007 where this issue will be available on our stand (Area 42, stand no. 14). There is also a selection of other interesting stories from all corners of the world. I am very pleased to announce that two new editors have joined our editorial team. Mark Anthony, based in the UK, will cover the European demolition industry and has been working for the magazine since the beginning of the year. PDi has also appointed Silvana Wirepa as Editor covering the Asia Pacific region. Thanks to Silvana we will be able to more continuously report what is happening in this region of the world. We are now in a process of appointing new editors and we recently hired Andrei Bushmarin covering Russia, parts of Eastern Europe and parts of Asia. We are now also searching for an Editor to cover Africa and another for South America. With a strong and competent staff of writers we can bring reliable and interesting news to you, our readers. I also would like to remind you to visit our website for the latest updates where you can also download the latest issue of PDi.

Words from O’Brien

Concrete Surface Prep & Polishing Surface preparation and polishing of concrete has generated phenomenal interest in the construction industry in just the past couple of years. A new seminar on polishing concrete was presented at World of Concrete 2006 to a sellout crowd of nearly 500 attendees because many contractors are looking to add to their current array of services offered. In response to this interest, many manufacturers of traditional saw blades are looking to offer these products to expand their product lines and customer base as well. A few manufacturers have already acquired small specialty firms or established marketing relationships with others to quickly enter the surface prep and polishing markets. So what is this interest all about? Is it the beginning of a new market opportunity or just a passing fad? Grinding and polishing of concrete is actually not a new concept. Grinding of concrete highways for concrete pavement restoration was introduced over a quarter century ago and today is well accepted by many state departments of transportation as the preferred method to maintain concrete highways and roadways. But this new interest in polishing concrete for commercial, and even residential applications, comes more from the stone industry rather than the concrete industry. Polishing and grinding of stone is a mature market and has been the accepted method to finish granite, marble and other stones for residential and commercial applications for years. Interest in surface preparation and polishing of concrete is very high right now and represents a segment of the construction field that is in its infancy. The contractors serving this market tend to be smaller firms who often do this work as a supplement to their other business. Awareness of the specifier community to the advantages of concrete polishing is very low. Consequently, knowledge of

concrete surface preparation and polishing applications is limited, as is current demand for surface prep and polishing services. But that is likely to change. In industrial applications, the benefits of a concrete polished floor in warehouses or showrooms include a floor that is structurally sound, harder and more durable and with lower maintenance costs than floors requiring sealers, waxes or epoxies. In addition, polished concrete offers increased wear resistance and it won’t break, chip or peel. It provides better reflectivity and is more environmentally friendly. It also can offer a decorative finish when the aggregate is exposed. It can also be stained in a variety of ways. Polished concrete floors are essentially maintenance free. After polishing with diamond tools, the only maintenance that is needed on a concrete floor is the removal of dirt, oils and other materials that could stain it. In order to accelerate the penetration of concrete surface preparation and polishing to the specifier community, standards and specifications will help establish levels for quality of work and training will help contractors provide a consistent level of product to meet industry standards. The current lack information in and structure of this market segment will improve and change. It will be up to trade associations to help set the standards to facilitate this market expansion. IACDS member associations are well suited to take on the challenge for this exciting new opportunity.

Best regards Patrick O’Brien President IACDS

New Bobcat European Logistics Centre A new European Logistics Centre for Bobcat products has opened at Puurs in Belgium. Owned and managed on behalf of Bobcat by the Fiege Group, the new Megacentre Puurs II facility is responsible for the procurement, distribution and transport of new machines and attachments for Bobcat in the European Served Area covering Europe, Africa and the Middle East. The new facility represents the next milestone in the ongoing cooperation between the Fiege Group and Bobcat. It builds on the work the Fiege Group has been carrying out since 1998, handling logistics for Bobcat spare parts from a facility at Mülheim an der Ruhr in Germany. Fiege Group, which has its headquarters in Greven, Germany, is among Europe’s leading logistics providers and generated sales of Euro 1.75 billion in 2006. Its competence lies in the development and realisation of integrated, holistic supply chain systems. Fiege Group has a workforce of around 21,000 worldwide with more than 222 branches and facilities based in 18 countries.

Hope and Faith School Pupils at an Indian school for the deaf and dumb are benefiting from new classroom equipment and a healthier future thanks to the support of UK based Extec Screens and Crushers. The slum area of the city of Nasik, in the Maharashtra province of India is a tough place to live and for many young people, education is seen as an escape route from poverty. However, the poverty itself has led to a lack of educational facilities along with a range of health problems in the community. Schools are in a poor state of repair and lack basic amenities and there are virtually no facilities for those with special needs. Extec has been active throughout India for the last seven years and Head of Extec’s India

operation Swapan Das, together with Extec Operations Director Ian English, came across the slum areas of Nasik during a business trip. They were saddened and shocked by what they saw but found a glimmer of hope when they came across a school for the deaf and dumb right in the middle of the slum area. Ian and Swapan spoke to the staff to find out what they could do to help the school and went back and discussed some ideas with Extec’s customers. The customers were keen to help and unanimously agreed that instead of receiving gifts from Extec at Christmas, the equivalent money should be donated on their behalf to improve facilities at the school. The initial £15,000 donation at the end of 2006 is backed by Extec’s pledge to continue supporting the school to guarantee its survival. Through Extec’s support, pupils can now receive a proper education in a healthy working environment. They now have large rooms and tables designed specifically to offer an excellent working environment. In addition, all of the pupils receive free health checks through the school. The school is proving to be an inspiration to the local community and have named it the ’Hope and Faith’ school providing the care and education that these children need and giving them renewed hope for the future.

Bobcat sold for US$ 4.9 billion Doosan Infracore, which bought IngersollRand’s US based Bobcat, Utility Equipment and Attachments business units for $4.9 billion in July, intends to keep current management and employees. ”The businesses we are acquiring have outstanding management personnel and engineers, which we consider to be the most important criteria of our acquisition strategy,” said Doosan Infracore vice chairman Yongmann Park. He added that Doosan plans to maintain current management and employees. Bobcat employs more than 2,600 people in North Dakota and has its roots in the state. It has been acquired twice since its local inception 60 years ago. The company, known for its skidsteer loaders, was owned by the Melroe family in Bismarck, who sold it to Clark Equipment in 1969. In 1995, Ingersoll-Rand bought it from Clark. The sale represents a realignment of Ingersoll-Rand’s business focus to global climate control, industrial and security markets and the proceeds of the sale will go toward enhancing those lines.

Hilti net income jumps 39% The Hilti Group has increased net income to

271million Swiss francs for the 8-month period January to August 2007, up 39% on 195 million Swiss francs in the same period last year. Sales were also up 16% from 2,647 million to 3,064 million Swiss francs and operating profit jumped 35% from 248 million to 334 million Swiss francs. Hilti expects the number of employees will also continue to expand, reaching approximately 20,000 by the yearend compared with nearly 18,000 at the end of 2006. The company reports that the construction sector enjoyed a positive economic environment over the first eight months of the year. In North America, where growth in the construction industry is less dynamic, and where the current real estate crisis in the United States is also having a limited influence on Hilti, a good, single-digit growth rate in US dollars was achieved thanks to the ongoing process of expanding the capacity of sales channels. All other regions grew at double-digit rates. The Hilti Group expects the positive economic environment to continue and is also counting on a significant increase in sales and net income for 2007. This positive development may be weakened somewhat by deterioration in currency relation. ”We have a good market environment and are very pleased with our development,” says Hilti Chief Executive Officer Bo Risberg. ”But we cannot rule out the possibility that uncertainties in the financial markets may eventually have an influence on the construction industry. We believe that there will also be good momentum for the building sector in 2008 and that we will further strengthen our position in the coming twelve months. While continuing to focus on providing innovative products and services that provide customers with added value, we will also continue to expand our sales capacities.”

New German show “recycling aktiv” surpassed expectations At its première the ”recycling aktiv 2007” surpassed the high expectations and despite some unfavourable weather around 6200 visitors attended the three day recycling machinery exhibition from 5 to 7 September at the Karlsruhe / Baden-Baden Airport. The high proportion of more than 90% trade visitors, including many international specialists particularly pleased the exhibitors and several sales were made. For example, IUT Beyeler, a Swiss manufacturer of scrap metal shears, sold 12 small machines. The owner Peter Beyeler, expressed his satisfaction about the concept and organisation of the exhibition and said: ”The extraordinary high number of transactions speaks for the unique professional competence of the visitors that set this trade fair apart from all others. Here were almost only decision makers.” The Minister of Environment Affairs of the Federal State of Baden-Württemberg, Tanja Gönner, assumed the patronage of the exhibition and opened the show. She sees the exhibition as being in touch with a modern recycling

First Finmac F16 delivered The first Finmac F16 demolition robot from the Finnish demolition robot manufacturer Finmac Demolition Oy has been delivered by one of Finmac’s distributors Atmos AB to the Swedish concrete cutting company MSF Betonghåltagning. DEMOLITION WITH REMOTE controlled machines was introduced many years ago by Brokk AB, which now dominates the market. With a remote controlled demolition machine the working environment is radically improved as they are electrically powered and do not pollute the working area. Also as they are either cable or radio control the operators do not need to stand in a potentially dangerous area where they can be hit by falling debris. They can also have a better view of the demolition operation. According to Finmac their machine with radio control, as standard, improves efficiency with more then 500 % compared to handheld machines. Demolition robots like Finmac and Brokk are often used for demolition purposes related to renovation, concrete cutting, bridge renovations, sewer cleaning, in process industries and nuclear plants.

Finmac F16 is controlled by a Can Open system by radio or cable if needed. A built-in service module has several functions that prevent unwanted stops. It signals service, filter change, machine errors and several other parameters, making the operation safer and easier. All messages from the service module can be forwarded by phone, internet or ethernet connection to a service company or dealer. Finmac F16 weighs just over 1.6 t. The boom reach is more then 5 m and it can be extended another 500 mm.

First client and first distributor Finmac’s first distributor is Atmos AB and was founded by Måns Persson a couple of years ago. Besides selling Finmac, Atmos is also the dealer for other Finnish products and compact equipment from Avant. Finmac’s first client was Malte Andersson from MSF Betonghåltagning, a well known concrete cutting and light demolition company in the Stockholm region.

“The King of New York City” Nothing is like a construction site on Manhattan. It can be summarised in one word as “chaos”. And in this chaos, despite a stained national economy, construction machinery is sold like never before.

Husqvarna Construction Products “tough guy” in New York City, Bob Paccione.

IT IS AN EAR-SPLITTING NOISE. Construction workers are running up and down on the large steel beam construction. They are wrecking, drilling, cutting, grinding, welding, hammering and most of all shouting.

Juilliard School by Lincoln Centre I am on Manhattan at Lincoln Centre, the cultural heart of New York with several arenas for music and drama, including The Juilliard School, which is undergoing an extensive renovation and extension. The project includes more then 50 different sub-contractors led by the main contractor JC Turner Construction Company, which has about 40 employees on the site. In total some 210 construction workers are involved on the project. The extension towards Broadway covers some 12 000 m2 (130 000 sq ft) divided in five stories. The first stage of the project will be finished at the end of October and second stage at the end of next year. The demolition work is being performed by New Jersey based Waldorf Demolition, headed by site manager Benedict Colombo. “We have about 25 men plus four machine operators on the job. The work we are doing is mainly indoor renovation demolition with a few heavy jobs. On this stage we are just finishing up our 10 weeks on the job,” says Benedict Colombo.

Waldorf Demolition is a family owned company and the current company was founded in 1997. But the Waldorf family has carried out demolition jobs in the New York City area since the 1930s. Today the company has about 350 employees. Some demolition jobs have been sub-contracted to the Port Chester based company Robo Breaking mainly using Brokk demolition robots and is considered a specialist in the US with Brokk machines. The company’s fleet contains about 30 Brokk machines. Besides the demolition contractors two concrete cutting firms are working on the job. These are Tomahawk Concrete Cutting and JP Hogan Concrete Coring and Drilling. Several openings for doors have been made with hydraulic and high cycle wall saws and some 80 holes of varying diameters for ventilation, water, plumbing and electricity. The flat sawing has been done by Waldorf Demolition. “If you are specialised and are good at what you are doing there is always job for you,” says Waldorf Demolition project leader Joe Colella. “But knowledge is not enough. You need to have the right equipment and know how to handle them. We invest continuously in new and more efficient machinery,” adds Benedict Colombo. Equipment suppliers have representatives on site, which is typical of the way suppliers operate in New York. These included Brokk representative August Scalici who has sold its first Brokk machine to Waldorf Demolition. The company used to subcontract this type of work but now intends doing it themselves with their new Brokk. Another supplier on the site is Independent Equipment Corporation with a big portfolio of products including Husqvarna Construction Products. “We have delivered a lot of equipment for concrete cutting like power cutters, wall saws and flat saws as well as diamond tools for just this project. Waldorf is a great client,” says Independent Equipment Corporation representative Mike Lamb.

A veteran with a tough attitude I visited the Juilliard project with the help of Husqvarna Construction Equipment salesman in NYC, Bob Paccione, who is a veteran in the diamond tool and concrete cutting industry. He knows his job and his market and is a great asset for HCP. Only the states of Texas and Florida are as big markets as New York City for HCP in USA. Before working for HCP Bob Paccione sold diamond tools and machinery


From the left, Joe Colella from Waldorf Demolition, Mike Lamb from Independent Equipment Corporation, Benedict Colombo and Justin Matos from Waldorf Demolition. to the stone industry for 16 years. Now Bob Paccione mainly works indirectly with heavy users in the building and construction industry selling mainly to distributors. Bob Paccione and HCP have about 25 larger distributors in the New York City area, including Independent Equipment Corporation. “NYC is a tough market with many players. If you want to be competitive you first need good product, excellent availability in delivery and service and you need to be there where your clients are, on the worksite,” says Bob Paccione. “HCP can offer that and the name Husqvarna has 75 years experience in the US market, so the name change from Electrolux was not a so big deal for me. But if our products had not met the target we would be in trouble. Most companies that I work with are independent and don’t belong to any larger chains. This demands a closer relationship and more regular contacts with each distributor.”

Price war on diamond tools Diamond tools dominate Bob Paccione’s business and represents around 70 % of the total sales. But the competition is terrible he says. “In my opinion we have the best tools and the best equipment but on the diamond tools we are competing against outrageously low prices and sometimes very bad quality. Everybody wants to get into the NYC market that is valued at some $40 million when it comes to diamond tools and about $10 million for machinery,” says Bob Paccione. “On the machine side, which is the remaining 30%, I don’t experience that same competition. We have the best products and the best prices and that is what our clients want.”

Wall sawing in the basement of the Juilliard School.

Competition in diamond tools is very scattered on many different producers while on machinery most of the competition comes from Diamond Products, owned by Tyrolit. The American manufacturer EDCO is also a strong player in the New York City area.

Floor grinding a growing market On the corner of 66th street and Broadway. In the background the extension of the Juilliard School.

Bob Paccione also sees good potential for the products that have come with the recent HCP acquisitions of King Concepts floor concept machines and tools and American Soff Cut’s flat saws for cutting joints in green concrete. Soff Cut has a very strong name in USA with their unique method for preventing cracks in concrete surfaces. Floor grinding is also a popular method for preparing concrete floors. Even though this method has been growing in potential there is still a lot more to do on the US market. “Soff Cut and King Concepts were new product areas for me but after some time with the products it is my opinion that they have good potential with my clients,” says Bob Paccione. “At our head office in Olathe, Kansas we also have a well equipped training centre were I regularly send our clients for training in both our existing products and our new ranges like King Concepts and Soff Cut.”

A growing new opportunity There is about 30 billion square metres of concrete floors requiring renovation, grinding or polishing around the world today and is estimated to be worth about EUR 97 billion (US$ 136 billions). This is considered to be a great new business opportunity for our industry, but is it ready to take it on? PDi spoke to HTC, the strongest company in this business about its operations, the industry and the future. These statistics come from a recent investigation made by an independent consulting firm and of the 30 billion square metres, Europe and USA accounts for about two thirds. The remainder is in Asia, Middle East and South America. With these figures it is easy to understand why concrete floor grinding has become such a big issue and why concrete surfaces can be used as a final floor.

Concrete as a final floor product Up until the mid 1990s concrete floors were seldom used as a final flooring surface. When the floor needed

to be renovated, glue, epoxy and coatings were often removed by flooring or cleaning companies, which applied them in the first place. But as the equipment for concrete floors developed during the 1990s other firms started to consider concrete floor grinding as a potential new service. These companies were to a large extent professional flooring companies, light demolition contractors, concrete cutting contractors and firms working with renovation in general. Now there is a clear group of professional floor preparation contractors working with the latest technology. But this change probably would not have happened if a completely new range of grinders and machines for floor preparation had not been developed in the 1990s.

Single, two, three and four From the 1950s until the beginning of 1990s the common floor grinder was equipped with either one of two grinding heads. In 1992 the company HTC Sweden AB developed its Dianova that had 3 grinding heads powered by an electric motor and belts. The principle was unique and offered many advantages, such as producing a better grinding profile, better balancing as well as higher efficiency and easier handling. The principle was also patented and should be considered the basis from where other systems have been developed. At that time HTC Sweden had a cooperation with a Dutch flooring contractor that was using HTC’s equipment. This contractor, or the people in it, decided to set up their own production of floor grinders and launched the brand Diamatic. The initial grinding head principal was very similar to HTC’s base concept and was therefore changed. Among other things belts were replaced with gears.

Diamatic also patented their design. These two new grinding principles became dominate and several variations on these base designs appeared on the market during the 1990s. A similar story happened in 2000 when the Australian manufacturer King Concepts developed and patented a 3 headed system, but with dual motors. The three principles are generally very similar and the two later ones are similar to the original HTC’s principle developed by Håkan Thysell in 1992. The latest development from HTC is the 4 headed grinding system, which was first introduced on the remote controlled HTC 950 RX. The 4 headed system gives a better grinding and polishing pattern as well as a smoother, more balanced and more efficient work. The 4-headed grinding system is also patented by HTC Sweden AB.

A handful of professional players The market is now flooded with different types of floor grinding equipment. But most of them are not developed for professional users and the quality is very variable. There are only a small number of manufacturers of professional equipment and HTC Sweden, Diamatic and King Concepts are the biggest. Diamatic was acquired by Blastrac a few years ago and King Concepts by Husqvarna Construction Products in 2006. Other manufacturers include German Schwamborn, Swedish Floormate by Sandvik, US manufacturers Innovatech, Eagle, VIC International, EDCO and Ravan Enterprises, Swedish Scanmaskin, German Contec and UK manufacturer SPE. PDi magazine and its Scandinavian sister magazines has followed HTC’s development almost since the beginning and seen new technical designs born and the product range grow. HTC now has three business concepts, the machines, the Superfloor System and the Twister System. It also has the biggest range of machines, containing 12 different models and sizes from the smallest HTC 130, HTC 400 DS/VS, HTC 420 VS, HTC 500 S/E, HTC 650 HDX, HTC 650 S/E Classic, HTC 800 HDX, HTC 800 Classic, HTC 800 H3, HTC 950 RX(tm), HTC 1500 iT and the biggest HTC 2500 iX. The HTC 2500 iX has a capacity to produce up to 1000 m2 of HTC Superfloor polished concrete per grinding day. The machine has been well received since it offers an industrialized way of producing floors. HTC development of diamond tools is also very extensive with new products launched several times a year. General characteristics of the HTC machines are that they are highly effective for floor preparation, grinding and polishing. Håkan Thysell says that he From right to left: HTC Sweden AB chairman and majority shareholder Håkan Thysell, majority owner and President Sten Jeansson in front of the HTC 2500iX mega grinder.

does not see the same kind of need for milling and shot blasting machines in the future as today’s grinders with new tooling concepts are so efficient and are able to handle these tasks up to removal of 10 mm of coating. The HTC machines offer a good capacity both for floor preparation as well as concrete grinding and polishing and can be used for numerous applications. What HTC’s has invested a lot of time in is to create the best type of grinding pattern and a smooth surface in a minimum of time. They are as useful on both new and old concrete floor and removes glue, paint, screed and other coverings efficiently. HTC expects to achieve a worldwide turn over of some EURO 35 million this year (US$ 50 million). The company employs about 160 people worldwide at its operations in the USA, Germany, United Kingdom and the recently opened premises in France. Target in 3 to 4 years is set to reach over EUR 100 millions (approx. US$150 million) HTC estimates its worldwide market share is about 25 %. ”I would say that we are growing in all our product areas and all are just as important and with that I mean tools, machines and training,” says HTC President Sten Jeansson. ”But to highlight a couple of things I think our Twister system has great potential and it is connected to the soul of the company, our grinding machines. Secondly we trust very much that our large scale grinder will become more of a common tool for floor grinding, as they are so efficient. It is a big investment, but with a very short pay off. The 1500 machine grinds 30 m2 per grinding hour which I think is amazing.” It started with the grinding machines and specially designed diamond tools for floor renovation, which provided the idea to create a system to grind and polish concrete to a finished product. But a polished concrete floor needs to be maintained in an easy and environmentally friendly manner, which gave rise to the Twister method. ”It was around 3 pm one January morning in 2005 I got the idea of Twister. Since then I believe that Twister is going to be our biggest product invention, together with our machines and the Superfloor system, we have made,” says HTC chairman and majority shareholder Håkan Thysell. ”Twister is an ideal product, free from chemicals and very simple. It can be used on any type of floor and any type of machine and does not necessarily need to be connected to the Superfloor idea, but Twister is a great promoter of our Superfloor.”

Focus on development Patent protection and training Even with great potential in Superfloor and Twister systems it is still the floor preparation segment that is biggest for HTC. The European market is the strongest, but the company is continuously taking market share in the US every year and several other markets. Other parts that have a growing potential are China, Middle East, India and Asia Pacific. The company has recently set up new distributors in China and New Zeeland. The new 6500 m2 production facility in Söderköping, Sweden, will be extended with a 2500 m2 training and demonstration centre. Every year HTC invests millions of Euros in product development and 12 persons are solely working with these tasks. In addition the company registers new patents for close to EUR I million per year. ”Our investment in new developments as well as our patent philosophy is very important for our growth,” says Håkan Thysell. And with the company’s tough 3 to 4 year target it needs strong implementation of the Superfloor and

20

Twister systems, continuous product development and development of the sales network with more distributors and more training. ”Honest and serious competition is also good and necessary and brings the whole industry forward. Companies that invent instead of copying us are good for the business. What I am a bit tired of is chasing companies that infringe our patents,” adds Håkan Thysell. HTC has been and is still the dominant manufacturer, but since Blastrac acquired Diamatic the new setup had been expected to be a strong challenger to HTC. So far the market has not seen such a strong position from Blastrac/Diamatic, but at Bauma the company, still headed by Diamatic’s founder Joop Müller, introduced new products. Joop Müller said that Blastrac’s strategy is to increase their market presence radically in the near future. ”We have the know how and the capacity, coming from Blastrac and the former Diamatic, to offer a very compatible range of products and our participation at Bauma is proof of that,” said Joop Müller. The Blastrac and Diamatic products displayed on their respective stands included the Blastrac BMG835 floor grinder with a grinding width of 835 mm and the self propelled giant grinder BMR85D, which can be equipped with many different types of attachments, including floor grinding and polishing heads. It also has a large integrated dust extractor and a water tank. An interesting change is Husqvarna Construction Products extending their product segments, including wider spectra of machines and equipment for concrete preparation and renovation. The floor preparation and polishing industry is considered very interesting, which resulted in the acquisition of King Concepts. It appears HCP is very determined to challenge HTC in a way that the market expected would come from Blastrac/Diamatic. King Concepts represents three models of machines for floor preparation and systems for polishing concrete floors up to super finish. The range is still narrow and needs a stronger and more powerful presence in the market. Undoubtedly HCP is able to provide that. In terms of diamond tools development and production there are also no limitations when in the hands of HCP. With these three large players the near future should be quite interesting. Other manufactures should not be ignored, such as the German company Schwamborn, which has a lot of experience developing all kinds of machines and equipment for floor preparation. Recent years have seen several new products and at Bauma the company displayed the new floor grinder DSM 430 SL, the patented chisel system OMF-250 and the new SBCrystal system. SB-Crystal is Schwamborn’s new concept for grinding and high gloss polishing. Some years ago the Swedish manufacturer Hagby launched a series of grinders for floor preparation named Floor-Mate and were received by the market. Some time ago Sandvik acquired the company and was probably a strategic investment due to their production of diamond tools and drill rigs for surface drilling and drilling systems for mines. The floor grinding activities has, as it seems, been dormant since the acquisition. More aggressiveness has been shown from another Swedish manufacturer Scanmaskin. The company is fairly young in terms of developing floor grinding equipment but has had positive development since 2003. The most recent novelty is their remote controlled grinder Scan Combiflex 700 RC. (See feature on pages 24 and 25). The US market has been slower in adapting the concrete floor grinding and polishing methods used

in Europe since the early 1990s. But this is appears to be changing fast. Propane driven machines are still very common and US companies in this segment besides HTC, which is the biggest, are EDCO, Eagle Solutions, VIC International, Ravan Enterprises and Innovatech. HTC Sweden has, since 2004, its own US company located in Knoxville. Most of the production is done in Sweden but functions for US adaptation, sales and marketing, administration, training and service are located in the US premises, which has about 35 employees. VIC International, once a distributor of HTC equipment, has a profound knowledge within equipment, machines and tools for all sorts of flooring materials. The company offers a wide range of products for this purpose but also has a line of floor grinders and equipment for polishing concrete. The product range contains the largest VIC 3200 Grinder/Polisher, the ConcreteMedic(r) Multi Surface Machine and the edge grinder VIC EdgeMaster. VIC also offers the Floor-mate range from Sandvik. Innovatech, also a former HTC distributor, is a young manufacturer of floor grinding equipment. Their biggest machine is the Predator, which offers good stability and efficient grinding. It is powered by a 15 HP (11 kW), 3 phase, 460 V high power motor and has a grinding width of 819mm, making it a good choice for contractors working in large areas with both concrete grinding and polishing. The second largest Innovatech grinder is the Delta followed by the Omega grinder and the recently released Predator 850 edge grinder. The Predator is also equipped with 4 grinding heads similar to the HTC 4 head system and the two companies are now in a process of investigating possible infringement of patents. EDCO is probably the biggest supplier of this type of equipment in the US and offers a complete line of Surface Preparation Equipment. Their equipment can take up linoleum, ceramic and vinyl tile. They can also clean surfaces by removing carpet backing and coatings, such as tile adhesives, epoxies, urethanes and paints from concrete, asphalt, masonry or steel and remove deteriorated concrete and create a desirable surface texture. EDCO has four models of floor grinders, including one edge grinder. One of the models is also equipped with a four-headed grinding system. EDCO grinders are available as gas, propane or electrically powered. EDCO offers good quality products that require little maintenance, saving time and labour. EDCO’s equipment is built in the USA and the company has provided contractors with solutions to resurfacing problems since 1959.

Special training PDi understands HTC, Husqvarna Construction Products with King Concepts, VIC International and Innovatech offer special training seminars on their equipment, including basic training in how to polish concrete to a final floor product. HTC Sweden were first with this idea when founding the HTC Academy that is now offered at the company’s premises in Sweden, Germany and United States as well as at HTC distributors. At this year’s World of Concrete Equipment Development Company, Inc. announced the CONTRx Polishing Systems for polishing concrete up to a final floor product. The company has been producing the EDCO brand equipment since 1959 for the concrete repair, restoration and surface preparation industry. CONTRx Systems is a new brand single and dual-disc system for grinding and polishing.


Grinding with Hilti like never before Grinding is not always connected to floors. It can also be handheld equipment for other purposes. Hilti is known for its revolutionary DG 150. A grinding system that, according to Hilti, smoothes the way to higher productivity without raising dust.

A brushless motor, diamond cup wheels that achieve twice the material removal performance, a self-cleaning vacuum cleaner and life expectancy many times that of conventional grinders, this is the stuff of genuine innovation. The Hilti DG 150 has been designed specially for professional use and to achieve perfect results in applications on coated or uncoated mineral materials, often up to twice as quickly as conventional grinders.

Efficient dust removal Consisting of a handheld grinder, special cup wheels and a powerful vacuum cleaner, this system keeps dust to an absolute minimum, making it ideal for use in sensitive environments such as hospitals, office buildings and hotels. Dustless grinding also means efficient, professional grinding. A working environment without any noticeable dust emission is not only less hazardous and clearly more comfortable to work in, it also boosts productivity.

“Boomerang” segments Special cup wheels with an innovative “boomerang” diamond segment configuration remove material up to twice as fast as conventional angle grinders, particularly on mineral materials such as concrete. Thin coatings can also be removed without clogging or smearing: The new type B1 self-sharpening cup wheels not only ensure consistently high grinding performance, they also improve surface texture as the coating is ground off, thus saving time and further costs. Grinding concrete and screed: The Hilti DG 150 gives the surface a texture that ensures an optimum bond with coatings, paint or joint sealants.

Removal of concrete form exceeds, overlaps or thin coatings such as adhesive remains: With the Hilti DG 150, you remove and prepare the surface for the next step in one operation.

Dust resistant motor In contrast to tools with conventional universal motors, the rotor in the Hilti DG 150’s SR motor carries no electric current because it has no windings. This makes the motor extremely dust resistant because there are no windings to be affected by dust deposits or erosion. Together with its glass-fibre reinforced casing, the DG 150’s motor lasts ten times longer than the motors of comparable grinders. In addition, changing carbon brushes is now a thing of the past - the SR motor has no brushes!

95% mineral dust removal Not only does the Hilti DG 150 remove up to an incredible 95% of the mineral dust produced, the Hilti VCD 50 mobile vacuum cleaner employs the latest filter-cleaning techniques that permit long periods of trouble-free use. Its filter system cleans itself automatically at 30 second intervals, thus ensuring consistently high suction performance. No more annoying stops for cleaning the filter or changing carbon brushes are necessary. The dust hood’s practical opening section also provides unobstructed access to edges and against walls, making it easy to work comfortably on areas otherwise difficult or impossible to reach.

“What more can you ask for?” Hilti grinding tools: Above B5 and left the C1 Cup Wheels.

“Top grinding performance, maximum dust removal efficiency, virtually no maintenance and an unbelievably long life expectancy, what more can you ask of a diamond grinding system?”, a Hilti spokesman says. With the Hilti DG 150, professionals can work many times more efficiently and more productively. “We believe that this revolutionary system, because of its unique suction performance, will kick up a lot of dust among grinding specialists”, he adds.

First Pan-Europe Development and manufacture of systems for concrete floor treatment is showing a strong growth all over the world. One manufacturer aiming for a larger international markets share is Scanmaskin based in Lindome just outside Gothenburg, Sweden.

Scanmaskin is a family owned company developing and manufacturing systems for treatment of concrete and stone surfaces. Recently their products for grinding concrete to a final finish has taken a stronger foothold on a number of markets in Europe as well as systems for floor preparation.

Manufacturing since 2003 Father and son Claes-Göran and Paulo Bergstrand own the company, which was founded in 1975 and concentrated on heavy cleaning equipment. But at that time treatment of stone and floor surfaces was under consideration. As the company developed and became more specialised, it took on the whole process of treating floors of stone and concrete from the initial heavy cleaning stage up to the final polishing. For the past four years the company has produced its own floor preparation and grinding machines with its own patented power unit. There are three base models and more models are planned.

working easier and more comfortable for the operator. The new remote control drive system makes the surfaces smoother and more even. It is also equipped with a dust extraction system that radically lowers the amount of concrete or stone dust. As the machine is powered by batteries it is easy to move during operation and transport and when loading and un-loading. The medium sized model, Scan Combiflex 500, has been developed for grinding concrete, stone and terrazzo and is also efficient for removal of different kinds of coatings, glue and epoxy. For all of their machines Scanmaskin offer a large variety of grinding, sanding, polishing and ripping tools. The smallest machine is the Scan Combiflex 45 and is very popular with rental companies. It weighs 60 kg and is easy to fit in a normal station wagon. It has been developed for grinding concrete, stone and coatings and can also be used for grinding and sanding wooden floors.

Easy tool change The assortment The largest Scanmaskin floor grinding machine, the Scan Combiflex 700 RC, is sold mostly to professional floor preparation and grinding contractors working on large scale projects. This model is also common among the rental companies. According to Scanmaskin the benefits are many. It is very stable and durable and radio controlled as standard, which makes

Scanmaskin has a special system for easy change of tools called “SnapOn”. “Not one single screw needs to be to loosened or tightened. With a small rubber hammer you easily place the segments. When you are finished you release them just as easy. Some still prefer traditional grinding discs but most of our clients have switched to our Snap On System,” says Claes-Göran Bergstrand. Choosing the right segment for the material to be ground is a science. The diamond segments for grinding and removal are developing very fast and new types are being constantly released. In order to support their clients finding the right type of segment and also equipment for their applications Scanmaskin has developed special grinding guides. The guides are based on each Scanmaskin machine and show step by step what type of method gives the best results. The guides are available on the Scanmaskin website for downloading.

Rental, an important business segment All machines in the Scanmaskin range are also built for the rental industry as they have a simple design that can take rough treatment. There are no lose or sensitive parts that can break easy. According to Paulo Bergstrand their machines do not need much maintenance, which means lower maintenance costs compared to other brands. Training is included in the price of a Scanmaskin grinder. “We sell management just as much as products and the training takes place on the worksite, so the clients can get into operation immediately. It is important to us that our clients learn how to handle our machines in one of their own applications,” says Paulo Bergstrand.

Increasing export Scanmaskin is a part of Scanbolagen AB, which has a group turn over of about EUR 8 million.

ean, then Global Besides the head office in Lindome, Scanmaskin has its own sales companies in Norway, Finland, Latvia and Denmark. In total the group has 20 employees and 14 of these work in Sweden. They have their own distributors in the UK, Belgium, the Netherlands, France, Germany and the Czech Republic. About 30% of the production is exported but is set to increase radically over the next three years. “To work with distributors is quite new for us but so far everything has worked well and our business is increasing fast. We want to be pan-European and then global,” says Claes-Göran Bergstrand.

Facade restoration in Bern Over the years weathering has caused a lot of damage to the facade of the Federal House in the Swiss capitol Bern. It was in a poor condition and needed restoration and stringent restrictions were imposed so as not to damage the existing structure or disturb the surrounding environment. The task was to replace the façade of Bern sandstone according to its condition and degree of weathering. These parts are mainly the protruding profiled elements, such as windowsills, jambs and horizontal bands of stone or brick. Earlier and similar renovation has been done by electric or pneumatic hammers, but these types of vibrating tools create a lot of noise and can damage the structure. Local Bern contractor Carlo Bernasconi AG, won the contract for restoration of the Federal House facade. After several tests with a Demco Technic electric Cobra wall saw on a similar project, it was clear that it would be possible to make horizontal cuts into the defective stonework. The saw cuts were set at intervals of about 80 -100mm to then allow the defective parts to be removed piece by piece with hammer and chisel. In order to make the sawing even more

efficient a fast attachment and moving system for the wall saw was developed in cooperation with Carlo Bernasconi. Four vacuum plates from Demco Technic, connected with guide rails, were attached to the façade’s smooth components at intervals of 3 m. The compact Cobra wall saw was then easy to use between the vacuum plates.

THE NEW

Punchline The world has this year seen the launch of a number of new hydraulic breakers. This special report present some of the most common brands and most of them were displayed at the German Building and Construction show Bauma last April. There is a span of more or less 9,930 kg from the smallest, Bobcat HB280, to the biggest breaker, Atlas Copco’s HB10000.

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 F-Series 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.

World’s biggest 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.

New series from NPK 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 1221 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.

Ingersoll Rand showed for the first time at the Bauma fair 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 automatic two stroke operating system that combines the main energy production stroke with a patented blank firing protection system, that gives 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 SC-50 model.

Mono block breaker from Socomec Socomec’s main news in terms of breakers is 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.

12 tonner from Indeco Indeco from Italy did not release any new breakers at Bauma but the President of the company, Michele Vitulano, said that the they have 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.

Furukawa has released two “Second-Generation” large FSeries hydraulic breakers, the F22 and F45 weighing 1.6 t 3.1t. Designed for use with excavators from 16 to 50 t.

New range from Komatsu Komatsu Europe offers a complete range of hydraulic breakers for mini, midi and large excavators from the 1 t class PC09 to the 60 t size PC600. Breakers for skid steer loaders and backhoe loaders are also available. The new breakers offer the highest levels of impact energy, an essential productivity element, by combining gas and hydraulic pressure. They are proven to deliver best-in-class impact energy, as documented by an independent testing agency. A smooth recoil action results from a nitrogen-filled, low-pressure gas system that absorbs piston recoil, reduces vibration and noise, recycles energy for the next blow and improves efficiency. The breakers’ simple design is based on just two moving parts, which are a piston and a control valve. Exceptionally reliable, the breakers require minimal maintenance, due largely to their streamlined design. Instead of a conventional rubber bladder-type accumulator, which has to be replaced periodically, Komatsu breakers have a metal orifice that never wears out, so never needs replacing. A convenient auto-grease system is also available, further reducing maintenance downtime. An optional kit facilitates underwater use.

Sandvik Mining and Construction used Bauma as the worldwide launch pad for a new range of Sandvik Rammer hydraulic hammers designed specifically for use with backhoe loaders. Known as the BL range, the new hammers utilise proven Sandvik Rammer technology together with a number of new innovations to make the four new hammers ideally suited to rental, trenching and other backhoe loader duties. Based upon the proven Sandvik Rammer S 23 and S 25 hammers, the new four-model range comprises two standard and two super-silenced CITY models ready-to-mount on any backhoe loader. Equipped with compact, hard-wearing side plates, these new hammers fold away for safe, secure road transportation, allowing them to be deployed and stowed quickly to match standard backhoe loader work duties.

In the medium weight range, TABE has two models, the AGB-10, which weighs 921 kg, including bracket and is recommended for machines of between 10 and 16 t. This is the first model from the new GP family, which incorporates new hydraulic technology based on pure gas and allows for an impact energy that is 20% greater than with current technology. TABE is also launching the new AGB-575, which weighs 600 kg, has the new pure hydraulic technology and is aimed at excavators of between 8 and 15 t. In the heavy weight range for carrier machines of between 21 and 28 t is the new AGB-15, which weighs 1,470 kg, uses hydraulic and gas technology and improves the hammer’s impact energy by reaching between 450 and 700 strikes per minute. TABE is also launching the new 4,000 kg AGB 40 on to the market. During the meeting, TABE’s 20 years of experience manufacturing pedestal breakers was also highlighted. This auxiliary equipment, used primarily in main quarry breakers, helps to move and break blocks that, either because of their nature or size, prevent the correct use of the crushing machine. TABE currently manufactures 7 breakers, adapting them to the specific needs of each client or sector.

A growing potential for Hydrodemolition techniques New robot from Conjet

Hydrodemolition, a method to remove

damaged concrete by using high pressure water, has shown a strong development.

Since it was developed the technique has been refined continuously and

Conjet’s Robot 364 MPA is the latest model in the Swedish hydrodemolition equipment manufacturer’s renowned 360 range. Conjet is considered to be the biggest manufacturer of Hydrodemolition techniques and was once a part of Atlas Copco. The Conjet Robot 364 MPA, can remove concrete from numerous surfaces, including above and underneath the robot with a minimal set up time. Due to its improved multipurpose arm, which reaches up to 6m above the robot and 5m to the side, the new Robot 364 MPA can operate with a reaction force up to 2000N, which is equivalent to the force of a water jet

today hydrodemoltion is considered in many different applications where water doesn’t cause any problems. It is fast, efficient and leaves the operator, thanks to the remote control, far away from the actual demolition area. On the following pages some updates on what is going on in the business. 34

generated by a 550kW (700 HP) highpressure water pump. The new features on the Robot 364 MPA include hydraulically height adjustable steering wheels that add an additional degree of freedom for positioning the feedbeam with its integral jetting lance and individually hydraulically extendable drive wheels to optimize robot stability. In addition the design of the new multipurpose arm offers higher accuracy in positioning and holding the feedbeam. The closed loop control system features the latest state of the art PLC (micro computer) and a new control box controlling the hydrodemolition process. There are nine pre-loaded programs for the most common hydrodemolition tasks and in addition the operators can store up to eleven programs with their own set up parameters.

Conjet to display Robot 322 at SAIE in Bologna Conjet AB will use the International Building Exhibition SAIE on 24 - 28 October in Bologna, Italy to display the company’s compact hydrodemolition Conjet Robot 322, the smallest unit in its comprehensive range of high pressure water-jetting equipment, which selectively removes weakened and damaged reinforced concrete from numerous structures. The compact, lightweight Conjet Robot 322 is exceptionally manoeuvrable and ideal for working in confined spaces and areas inaccessible to larger equipment. It is very narrow and can pass through an 0.8m to 1m wide opening, depending on attachment tool. This makes the Robot 322 ideal for operating in tunnels as small as 1.7m diameter with rotor attachment or single nozzle, culverts, inside concrete box girder bridge decks and under bridge and quay decks. The Robot 322 is also exceptionally efficient for use in numerous industrial cleaning applications and has been designed to operate with a reaction force from the water jet of 1,400N. The Robot 322, which will be displayed by Conjet’s Italian distributor Roald di Codecasa & C.s.n.c, in Area 48 stand G/53-H/52, consists of a self-contained, crawler-mounted undercarriage, electrically powered with an integral control system. This allows progress of the hydrodemolition process to be remotely and safely controlled and monitored away from the hazardous cutting area. The Robot 322 can adjust the width of its undercarriage to improve stability when operating and is equipped with a single oscillating nozzle.


The technique to use high-pressure water for the removal of damaged concrete was originally a Swedish invention starting with two different companies. One of them was Aquajet Systems AB located in the south of Sweden. Now there are a few more manufacturers in Sweden, USA and Japan.

A Swedish Invention Just outside the small village of Holsbybrunn in the south of Sweden Aquajet Systems has its head office and production plant. It is one of very few companies developing and manufacturing hydrodemolition equipment.

Developed in Sweden during the early 1980s Hydrodemolition or selective hydrodemolition is a rather new technique and was developed by just a few key people in Sweden. The technique has its roots in cooperation with the Swedish Road Administration. Hydrodemolition is an efficient and environmental friendly method for renovation and repair of concrete structures. By using water with a very high pressure, damaged and deteriorated concrete can easily be removed without damaging the healthy concrete. Left is a perfect surface to cast on new concrete. Another advantage of using hydrodemolition is that it does not damage the reinforcement. The alternative, using jackhammers or hydraulic hammers, causes damaged to the concrete and rebar. Breakers create micro cracks, which allows water to permeate in to the undamaged concrete and corrode the reinforcement. Hydrodemolition does not cause any of these problems and offers also more precise removal. Earlier it was believed that concrete did not need maintenance. The industry counted on those bridges, pillars, parking decks, quays, tunnels, concrete basins and

power plants would stand forever. Today we know better and the circumstances that create deterioration have changed. In the northern hemisphere, where salt is used on the roads during winter, concrete deterioration is a big problem. Road deterioration is now also a common problem in warmer countries and damage is mainly caused by pollution.“In our business it is quite easy to record that pollution affects our concrete structures to a higher degree these days,” says Aquajet Systems President Stefan Hilmersson. Many concrete structures need continuous renovation and repair. Also new concrete structures can be repaired or adjusted with hydrodemolition techniques. Hydrodemolition offers a smooth technique to adjust what is wrong leaving what is right untouched.

Robot in three standard models Aquajet Systems manufactures one base model called Aqua Cutter. This base model has three standards that are series manufactured in Holsbybrunn. From these three standard models many different variations can be built using the wide variety of different attachments. Besides the actual robot and its attachments Aquajet Systems also manufacturers the Power Packs that deliver the flow of high pressure water. The Power packs contain about a 750 kW diesel engine and a high-pressure pump and housed in a sound isolated container. “Any application is similar to another. During the years we have developed special skills in manufacturing standard units that can then be tailor made to meet the certain specifications on each worksite. We often are commissioned to develop and manufacture special equipment for very complicated hydrodemolition tasks,” says Stefan Hilmersson. Recently Aquajet Systems delivered a tailor made hydrodemolition system to be used in a nuclear reactor in the United States. For an Austrian client the company has made systems that are developed to run on railway tracks repairing railway tunnels. The common worksite with need of hydrodemolition equipment is bridge construction or bridge repair projects.

95% on export As there are just a few suppliers of hydrodemolition equipment and Aquajet Systems has the whole world as its market. The majority of the systems are delivered to countries in Europe, USA, South America, and several parts of Asia, like Japan and Taiwan, as well as Asia Pacific, including Australia. Some 95% of the production is exported and the systems are sold mostly through agents and distributors around the world. Recently the company appointed a new agent in India. In USA they have a new agent that has been doing a tremendous job. Traditionally USA is a tough market to get in to but Aquajet

“We have strong organic growth and we can sell much more than we can produce,” says Aquajet Systems owner Stefan Hilmersson.

System has established a good foothold. The system delivered to the US nuclear plant is a real prestige job, for Aquajet.

Strong growth

Thanks to Aquajet’s knowledge of the hydrodemolition technique, design and production, the company focuses on delivering the highest quality products. According to Stefan Hilmersson they are very self-critical and retain new solutions long before introduction. “Quality must be 100% before it reaches the clients,” says Stefan Hilmersson. “Our development work is based on our contact with the users of our systems. We constantly discuss and test new ideas with our clients.” All product development, production administration, marketing and sales functions are based in Holsbybrunn. All assembly and documentation are also made there. Other companies make some components in the southern part of Sweden and in Germany and Italy. Most part of product development is improvements to the Aquajet technology. The biggest challenge is the development of the water jet in order to create a technique that allows the jet to reach in confined areas, such as behind steel rebar. The water is pushed through a hose by the use of a 750kW pump. After that the water needs to pass though a nozzle with a 3.5 mm diameter hole. In order to remove concrete it needs a pressure of around 1000 bar and 230 litres/minute. Something that Aquajet Systems is investing time in is to make the demolition sequence more efficient using less energy or power.

The use of hydrodemolition equipment has shown a continuous growth during the last decade and the last year has been very good. Aquajet is still a small company with about 15 employees and has had a strong organic growth during recent years. “We have seen an acceleration in our growth. What took 15 years before takes instead today 5 years. Right now we can sell much more than we produce and we will probably strengthen our organisation during the coming year. We will extend our production facilities as well as hire more personnel,” says Stefan Hilmersson. Aquajet are still partly operating in the same facilities where the company started. In the beginning the company was formed by Stefan and three partners. Today Stefan and his wife Marianne own the company. The other three partners founded a contracting firm in the same business named Swedish Hydrodemolition Techniques and they are doing very well in their business. “We were a great team that all had some knowledge about hydrodemolition,” says Stefan Hilmersson. That knowledge and a lot of courage and ambition have made Aquajet in to one of the world leaders in design and production of equipment for hydrodemolition.

Even if Hydrodemolition is a relatively new technique it has become well accepted as an efficient tool for concrete renovation. When a concrete structure is about to be repaired it is studies to devise the best repair method. Within the European Union there is a standardisation for this kind of work. Stefan Hilmersson is part of a team within the Swedish Standard Institute (SIS) named TK12 that is formulating descriptions and general regulations for concrete repair. Hydrodemolition is one of the methods recommended by TK12, which is now developing a EU standard. Other companies involved with TK12 include the Swedish Royal Technical University, the energy company Waterfall, CBI and ISSUE 4 - SEPTEMBER - OCTOBER 2007 •

Conjet launch new Powerpacks to 1000 hp Conjet has launched a new range of Powerpacks for supplying Conjet hydrodemolition Robots and Jetframes with high-pressure water. The largest and most powerful 750kW (1000 hp) unit delivers up to 342 litres/minute at 1150 bar resulting in high removal rates of concrete. The popular 480 kW and 360kW versions are housed in newly designed sound insulated containers, which also have oil spillage collection trays to meet environmental requirements. All Powerpack installations meet the requirements for sea and truck freighting in a 20 foot container for easy and economical transport. The layout of the Powerpack is based on customer feedback ensuring a

contractor friendly design, with the engine and pump area completely separate from the workshop area to maximize safety for operators. It is possible to open one entire side of the container, which provides for excellent access during ser vicing and maintenance. The air inlets and outlets are constructed as hatches in the container roof and can be completely closed when not in operation. This is a major advantage when operating in temperatures below freezing. Details of the Powerpacks will be available from Conjet’s Italian distributor Roald di Codecasa & C.s.n.c, in Area 48 stand G/53-H/52 of the International Building Exhibition SAIE on 24 - 28 October in Bologna, Italy.

Aquajet keeps Gotthard Tunnel on track in Swiss Alps Hydrodemolition techniques were successfully used on the Swiss railway line close to Gotthard using an 11.5m high tower and a new Aquacutter Evolution robot from Sweden’s Aquajet Systems to remove damaged concrete without affecting services on the twin rail track. Opened in 1882, the Gotthard rail tunnel remains one of the world’s spectacular railway tracks, winding through the Swiss Alps, but requires constant routine maintenance on its bridges and tunnels. The rail track winds its way through a series of tunnels to the entrance of the Gotthard tunnel. These include a concrete tunnel bridge constructed 18 years ago that crosses the 50m deep-sided valley. It was originally built in 1882 as an open steel bridge and exposed to avalanches. During the winter of 1998, the avalanches virtually filled the valley with snow almost to the tunnel bridge. Recent tests have shown that the 88.50m long bridge could have been swept away with the next avalanches and the Swiss Federal Railway SBB commissioned a study to make the bridge safe. The Federal Railway SBB has opted to reinforce the bridge and tunnel, restore the bridge bearings, refurbish cracks up to 2m deep and connect the tunnel bridge with special wall anchors to the rocks. Together with reinforcement for avalanche-loads, the bridge will be maintained and damaged concrete replaced. Swiss hydrodemolition specialist contractor Brugger was appointed to undertake removal of 220m2 of concrete using its latest Aquacutter Evolution robot from Sweden’s Aquajet Systems. The Aquacutter was used for the majority of the remedial work removing 180m2

while a hand held lance removed the remaining 40m2. A feature of the new Aquacutter is the removal of all sensors and electric cables from the front of the machine eliminating ingress of water, grease and dust problems. The Aquajet EDS system allows for unbeatable lance angle of ’attack’ without wasting energy from the jet of water. As much as + 45° on the Evolution model can be selected, ensuring full removal of concrete between and under the rebars. In order to cut 20mm of concrete on the outside of the tunnel bridge, Brugger opted to top the Aquacutter 6m standard tower with an additional 5.5m tower element to reach a maximum height of 11.5m. The robot tower was set to match the 10° inclination of the tunnel wall using a special support. The robot’s hydraulic pressure remained constant throughout operations on the 11.5m tower. The electric-powered robot used 122 l/min of water at a pressure of 1900 bar to safely remove the damaged concrete without causing any harm to the exposed steel rebar

Combi cutter and Cat pulls down 44 m feed silo A 44 m high feed silo on the dockyard of Messrs. Kaatsch in Plochingen had to be pulled down quickly, efficiently and with as less harmful environmental impact as possible. The sensitive demolition was among other carried out with a CAT 365 BL and a Atlas Copco combi cutter CC 3300. The demolition contractor GL-Abbruch GmbH, of Esslingen could not allow debris to fall into the river Neckar just 8 m away from the demolition site.

The upper two floors were pulled down using two 5 t mini excavators each equipped with a 200 kg Atlas Copco hydraulic breaker. A 3m high ramp was built to allow the excavator with long front equipment to carry out the rest of the demolition work. For this work GL-Abbruch (www.gl-abbruch.de) used a CAT 365 BL with a 33 m long demolition boom equipped with an Atlas Copco CC 3300 U combi cutter. This combination of an excavator with a working height of over 30 m and a demolition tool weighing 3.5 t is rarely seen in Germany. To minimize the amount of dust during demolition, the excavator was equipped with a water spraying system and spray nozzles in the area of the demolition tool. “The combi cutter’s design is ideal for the service on long front excavators,” says GL-Abbruch GmbH managing partner Gerhard Ludwig. “The two cylinders with the cutting jaws moveable on both sides prevent strains from being transmitted to the excavator boom. Nevertheless the cutter makes a powerful and quick bite.” The cutting force of 109 t applied at the tip of the teeth and 400 t at the cutters gives the CC 3300 U an ample reserve of power and makes it the perfect tool not only for pulling down buildings and for industrial demolition work but also for secondary crushing and material separation. For cutting steel structures a steel cutting jaw can replace the universal jaw.

“United in D A line-up of three

primary demolition attachments from Italian manufacturer Trevi Benne SpA have spearheaded the highspeed demolition of a pair of disused bridges in the heart of the French capital, as PDi’s Mark Anthony reports.

France, Italy and Austria are three countries divided and yet conjoined by the Alpine mountain range. And these three nations have combined once again on a project to demolish a disused two-bridge overpass that carried the RD 914 road through the Nanterre district of Paris with French demolition specialist Cardem using Austrian-built Liebherr excavators equipped with Italian-manufactured Trevi Benne attachments.

International Operation Cardem is a 50 year old company that can trace its roots back to a quarry industry past. Indeed, the company’s name is an amalgam of carriere (French for quarry) and demolition, the two activities for which the company is best known today. Employing more than 250 people and with an annual turnover of EUR 35 million, the company operates from locations across its native France including Paris, Lille and Lyon but regularly strays across neighbouring borders, working in both Belgium and Luxembourg. In fact, the company is currently involved in the demolition of the Espanol soccer stadium in Barcelona, Spain. In Nanterre, the contract to demolish the twin road bridges was aesthetically-driven. The 35-year old bridges were rendered redundant following the construction of a road tunnel on the nearby A14 route, freeing up for urban redevelopment some highly valuable land that lies between La Defense and the Seine.

Military-Style Planning Despite the international flavour of the contract, or possibly because of it, the contract was a model of military-style planning. With the demolition scheduled to commence during an enforced five-hour road occupation scheduled for 20.00 in the evening, the entire demolition team was gathered on site almost 12 hours in advance. Demolition engineers and machine operators walked the entire length of the bridge viaduct, highlighting possible problem areas and creating an agreed demolition programme, with specific Liebherr machines and Trevi Benne attachments being allocated to specific tasks. Meanwhile, a team of mechanics took the opportunity to check over all the machines that were involved on the site, greasing and making repairs as necessary. Equipment and attachments had been brought in from as far afield as Lille, partly to ensure that the contract had sufficient machine power and also to provide cover if any of the lead machines suffered a catastrophic failure.

Narrow Window “We have a very narrow time window in which to operate,” explains Cardem’s Jean-Francois Ascolan. “The contract requires us to take down both bridges, one on the first evening, the second the following night. We then have to remove all demolition waste to a recycling facility around 3 km away.” Talk on the site was of a contract so fast and smooth that a local resident going to sleep on a Friday night and waking up the following Wednesday would have missed the entire operation, finding only a bare plot of land where the 35 year old cast in-situ concrete bridges once stood. The demolition was, in fact, the culmination of a two-month programme of preparatory works designed to minimise the impact of the demolition process. In addition to preparing for the demolition process, this also involved some extensive traffic management works to minimise disruption to vehicular flow along the busy Avenue

42

PDi • ISSUE 4 - SEPTEMBER - OCTOBER 2007

Joliot-Curie and Avenue Arago. Indeed, on the night of the main demolition, the crossroads at the Boulevard de Bouvet that links the Avenue Jolio-Curie and Avenue Arago was closed temporarily.

Men and Machines The need to minimise the impact of demolition to local residents was reflected in the sheer scale of the men and machines in place on the contract. A total of 40 people were involved in the controlled dismantling of the two 360 m long bridges, including 20 excavator operators working in shifts. These were responsible for operating a total of 14 excavators, including eight Cardem-owned Liebherr units from 24 to 64 t, all of which were equipped with either hydraulic or mechanical demolition attachments. Indeed, the entire attachment fleet from Cardem’s Lille facility was shipped to the site, many items merely being held in reserve. Among these were a 13 tTrevi Benne HC 140, an 11 t HC 100 and a 4 t HC 40, all of which had been purchased specifically to tackle this contract. These joined a fleet of 10 Trevi Benne attachments in the fleet of Cardem which has been running the Italian-built tools for the past five years.

Big Attachment On the stroke of 20.00 hours, demolition work commenced. The new Trevi Benne HC 140 slung from a Liebherr 974 excavator spearheaded the attack, the unit’s 2 m jaw opening quickly getting to grips with the concrete that was 1.1 m thick in places. A key benefit of the Trevi Benne attachments is their hydraulic rotation which allows the operator to

accurately grip and crush concrete, regardless of the angle of approach. The HC 140 attachment, the biggest in the Trevi Benni range, also features powerful cutting blades set deep in the jaw. These quickly and effortlessly cut through the reinforcing steel bar, allowing the bridges to be demolished quickly and cleanly while facilitating greater “waste” segregation and recycling. The primary demolition tool was followed along the length of the bridge deconstruction by a smaller but still impressive 11 tonne Trevi Benne HC 100, also mounted on a Cardem-owned Liebherr 974. A rented Liebherr 954 rental machine equipped with a 4 t Trevi Benne HC 40 brought up the rear, rehandling and processing the broken concrete for later off-site recycling. During a series of 24 hour operations, operators were switched regularly to ensure that work continued virtually non-stop until the demolition was completed. Thanks to the planning of the Cardem demolition team and the sheer power of the Trevi Benne attachments, the demolition of the dual span bridges was completed on time and within budget, with more than 3,000 m3 of concrete being broken and transported to the recycling facility for processing and onward sale.

Consolidated experience of the building sector and a city that for more than forty years has been the international reference point for building tradeshows, offering specific solutions for every segment of the world of building and construction. These are the key strengths of BolognaFiere, the leading trade fair organiser which after creating one of the foremost European suites of trade fairs for the construction sector has exported its exhibition model and now offers Italian and European companies support with their business internationalisation programmes.

An exhibition layout divided up into theme areas, tools for speeding up access to the show (personal cards), infrastructures that allow the exhibition centre to be reached conveniently by any form of transport - BolognaFiere considers it a top priority to ensure that the links with the city and within the exhibition centre itself are adequate for a business event. The new Bologna-Fiera motorway toll booth is already in operation, making it even easier for professionals to reach the exhibition centre. The links to the railway station and airport are also extremely efficient. A number of major structural works inside the exhibition centre have also made it easier to get round the show including the raised connecting walkways between the halls and the new areas devoted to services.

From the architectural project to the building process SAIE has always been renowned for its attention to every segment of the construction industry, from architecture to building process innovation. The show is renowned for its previews of trends in the building world and is an important platform for debate between visitors and the top international architects who talk at the meetings devoted to the themes of greatest topical interest each year.

PDi • ISSUE 4 - SEPTEMBER - OCTOBER 2007

But it is also an event that focuses on INNOVATION as they key to development strategies, exploring this theme in relation to: PRODUCTS - In just three years the SAIE New Product Guide has become the most authoritative guide available to the sector, a publication that selects the most interesting new products displayed by exhibitors at the show and proposes them in a convenient format for professionals. Again this year the SAIE New Product Guide will benefit from the cooperation of the IUAV of Venice, which will select the most significant innovations at SAIE 2007, highlighting the main innovative trends and some particularly interesting products. EXHIBITION SECTORS – Over the years, the evolution of the exhibition proposals has led to the creation of new theme sections and focus events devoted to the most topical issues. One of the focus events in 2007 is Energy Efficiency. The most significant technical aspects of this theme will be explored during the exhibition and will also be discussed during the various debates. BUILDING PROCESSES – Rather than just presenting the most significant innovations, SAIE 2007 will for the first time be featuring a special area devoted to practical demonstrations to make the exhibition more functional than ever.

Core exhibit 2007: The changing face of Italy, cities between land and water In 2007 the SAIE Core Exhibition continues the cycle devoted to the changing face of Italy, focusing on waterfront cities. The changing face of Italy, cities between land and water analyses how the thin strip of land facing onto bodies of water is addressed in construction projects. This is a theme of great interest given Italy’s geographical characteristics and is explored in terms of the relationship between urban fabric and water and between water and the natural environment. At the same time it aims to provide an overall picture of the development of the infrastructure system for waterfront areas and of technical issues and materials.

SAIE and CRESME present the economic analysis of the Building sector Following the agreement between BolognaFiere and CRESME, the annual report on the building industry was unveiled in Bologna during SAIE 2006. Again this year, on the day before the opening of the show, BolognaFiere and Cresme will present the ECONOMIC ANALYSIS OF THE BUILDING WORLD, the major report on the state of the sector and the investment trends.

Improved Extec jaw makes SAIE debut Extec Screens and Crushers Ltd, now part of Sandvik Mining and Construction, will use the SAIE exhibition to display the company’s S-4 screen and the C-10+ track-mounted jaw crusher on Stand D91-E90 in Area 48. The new C-10+ builds upon the reputation of the larger Extec C-12+ and is designed specifically for small quarries, demolition sites, and recycling facilities. A vibrating feeder ensures a consistent flow of material to the 1,000 mm x 650 mm fully adjustable and hydraulically controlled jaw crusher. The jaw action can be quickly reversed to free blockages while a ”fast track” facility helps clear the machine of tangled steel reinforcing bar. The entire machine can also be raised hydraulically for cleaning and routine maintenance duties Also on the Extec stand is the S-4 screen, a new track-mounted mobile screen designed

for a multitude of quarrying, mining and recycling applications. Weighing 28 t the S-4 is the smaller model to the S-5 and shares many of the features and benefits of the larger

machine. The S-4 utilises two independently adjustable screen boxes to produce a screening area that is equivalent to a traditional 4.8 x 1.5 m screening system. The Extec Doublescreen system allows the first screen box to be used to remove fines in even the most cohesive materials, while the second screen box acts as a materials grader. As a result, the Doublescreen system is able to produce consistently precise material grades. The Extec S-4 is offered with a variety of optional extras, including a remote control system, shredder box for green waste applications and a vibrating grid.

Extec I-C13 in Siberia Heavy Duty Overband for Incinerator Plant

Deep within the Siberian wilderness, an Extec IC13 has been working for the Siberian Coal Energy Company (SUEK) crushing coal straight from the quarry. Following a large walking excavator, the IC13 is maintaining high production through the heavy snow and harsh materials, ensuring that SUEK can keep output of coal to a maximum. Because the conditions on site can deteriorate extremely quickly, production must be effective and fast when the weather permits, therefore the machine has to be reliable. The I-C13 offers extremely high mobility and flexibility along with

the necessary productivity that allows for it to be set up and crush coal very quickly. The Extec I-C13 combined with its many advanced features enable the machine to work in the most hostile conditions. The Impactor box by Krupp Hazemag SA produces high quality material with excellent consistency. The power provided by a CAT C-13 engine ensures that drive is constant, powerful and reliable while the new web and flange chassis allows the I-C13 to be used anywhere around the world.

Coventry & Solihull Waste Disposal Co Ltd is one of only a few local authority waste disposal companies remaining in the UK. They are a small privately owned waste management company, with experience in many aspects of waste management including incineration, public waste site and landfill. They are owned jointly by Coventry City Council and Solihull Metropolitan Borough Council and have an incineration plant, which runs nonstop 365 days a year. CSWDC purchased an Overband magnet 35 years ago to function within the incineration plant. Master Magnets recommended that CSWDC replace the old unit with an Oil Cooled Coil Wound (OCW) Overband magnet. The OCW overband has

a high magnetic strength producing 869 gauss at the required working gap of 300mm and more powerful than the previous unit, which could only produce 500 gauss. Due to the high magnetic strength the overband would be able to work at an increased operating gap if required enabling it to extract ferrous from a deeper burden, and at a faster speed thus increasing the feed rate. The overband, weighing just over 5 t, was designed and manufactured to fit directly into the incineration plant conveyor. CSWDC expect the unit to pay for itself within months, and the overband is expected to last for another 35 years or more.

graded material is produced from broken asphalt material with only one operator required for the mobile RM100 and OS100. The high throughput, even with steel reinforced concrete, plus remote controlled simultaneous crushing and manoeuvring operations from the loader, were key factors in Robert Thoma junior’s decision to buy the equipment. Waste pre-stressed concrete can be processed in a single pass to 0-32 mm with all steel bars being removed by the magnetic separator. The fact that the final grain size can be easily adjusted at the rotor using engine speed was the key criterion in a decision in favour of a RM100

RUBBLE MASTER high performance crusher. This decision saw the replacement of an RM80 immediately after Bauma at the civil engineering company Noller in Baden-Württemberg. ”The RM100 delivers an end product with a high market value and optimum grain distribution,” says Noller owner Joachim Noller. The crusher stands out through its extensive optimisation, also with minimum wear and operating costs, such as diesel consumption at only 20 to 22 l/h. The RM100 demonstrated its prowess in mineral processing after start-up. Limestone is fed using a wheeled loader with a 3.5 m3 bucket and recycled to make high-value 0-32 mm final grain.

New ICS 853PRO-FL concrete saw provides flush cut capability ICS has introduced a new concrete cutting chainsaw designed with flush-cutting capability. The 853PRO-FL Hand Held Saw has a special motor, drive sprocket and bearing support design now reengineered for durability and performance in heavy commercial use, with the unique ability to cut nearly flush to a wall or floor. The 853PRO-FL is built on the 853PRO Series Hydraulic Saw platform and uses exactly the same PRO Series diamond chains and guide bars as other ICS hydraulicpowered chainsaws. Now all the utility offered by a concrete cutting chainsaw, like square corners without over-cuts and the ability to plunge cut into concrete up to 24inches (600mm), is even further enhanced with the ability to cut 0.187" (4.5mm) flush to a wall or floor. The 853PRO-FL uses a proprietary rim style sprocket combined with a customized bar mounting design. This new product has been field tested by CSDA professional concrete cutters for over six months prior its release.

New cutting trolley with clear operator focus Top performance, easy to mount and extremely good ergonomics are the primary characteristics of Husqvarna Construction Products’ new cutting trolley KV 750, which has been specially designed for the power cutter K 750. ”Our new cutting trolley was totally and completely developed with the operator in mind. We have put a great deal of work into making it easy to operate and manoeuvre. For example, it has a handle that is vertically adjustable, which gives the operator the best possible work position. The KV 750 is a modern cutting trolley that fits the K 750 cutter perfectly,” says Husqvarna Construction Products power cutter Product Manager Håkan Aldén. The Husqvarna KV 750 is easy to fold up and convenient to transport. With the help of a quick fastener, it is easy to mount and remove the power cutter. When the machine is mounted, all controls are in place. The wheels are laterally a d j u s t a b l e, which makes the trolley easy to operate next to, for example, a kerb

or kerb stone. ”An important new feature is that it is possible to configure the trolley for right and left turns. This makes the work much more flexible for the operator, who no longer has to lift the back wheel,” says Håkan Aldén. ”It is also easy to adjust the cutting depth, fold up the machine when moving it and then come back to exactly the same cutting depth.”

New power cutter with less vibration and more power The new Husqvarna power cutter, K 960, combines more strength and increased user-friendliness as the result of using Husqvarna’s patented Dual Charge technology. The K 960 is a development of the K 950, and externally is

PDi • ISSUE 4 - SEPTEMBER - OCTOBER 2007

practically identical. However, underneath there are several new technological features. The new model meets EU requirement limits for handle vibrations of 5m/s, which means the cutter is approved for usage for an entire workday. ”It may sound like a contradiction, but the K 960 actually has more power than its predecessor and at the same time less vibration,” says Husqvarna Construction Products power cutters product manager Håkan Aldén. Several improvements include substantially reduced emissions and a more powerful front handle that makes handling the cutter even more flexible. ”The K 960 is not only easier on the body, it also contributes to a healthier work environment. Quite simply it is much more comfortable to work with than before,” says Håkan Aldén. Like its predecessor, the K 960 has

a 94 cm3 engine, with 4.5 kW power. The difference is the feeling of additional strength. ”The new poly-v-belt means less power loss between the engine and the cutting blade and the Dual Charge-system creates higher torque. This combination results in a power cutter, which, despite its modest weight, can handle very demanding tasks”, says Håkan Aldén. The K 960 has been equipped with a more powerful front handle, Husqvarna’s patented Dual Charge-system, and a new paper filter that reduces the risk for engine breakdown. The Dual Charge-system involves two intakes for the engine, one for clean air and one for a fuel mixture. Unlike conventional two-stroke engines, unmixed air is used to flush gasses out of the engine so the fuel is used more economically. No fuel mixture is wasted, radically reducing emission levels by up to 60%, so meeting the demands applicable in the US, where the cutter was initially launched, followed by Europe at Bauma last April.

ICS is “Brand” New ICS, considered the world’s leader in concrete chain saws and the creator of Diamond Chain Technology, has unveiled a new corporate logo designed to signal a strong new start for the global company. Although the new mark retains the same colour and typeface as the original logotype, the oval shape has evolved into a strong rectangle featuring a forward slash cutting through its right side. Complementing the corporate logo is a new product logo, a red diamond with the tip of a concrete chainsaw carving a perfectly square corner. Both logos sport a new tagline—CONCRETE. STONE. MASONRY. UNSTOPPABLE-designed to highlight the versatility of ICS saws. “Our logo design goal was to honour our 15 years of product evolution, but also create a launch pad for what will be a revolution in innovation and quality,” stated ICS President Jake Vanderzanden,, ”The new mark shouts strength, action, and forward motion, qualities I see as key to fulfilling our

mission of making our chain saws the eventual tool of choice for cutting concrete, stone, and masonry.” According to Vanderzanden, the new look is just the first step in what will be a larger renovation of the global company. Next up are a series of new products and programs, including tougher diamond chains, gas saws with greatly improved reliability, and a hydraulic saw that Vanderzanden says will make competing products look ”tame.” ”Our customers demand power, durability, and reliability. With a decade and a half of setbacks and successes under our belt, we’re ready to answer their needs like never before. Our new logo is just the tip of the iceberg.” The logos, designed in conjunction with Portland advertising agency Grady-Britton, are already a part the company’s websites, www.icsbestway.com and www.icsdownload.com, and will soon appear in all materials used by ICS for internal and external communications, sales, packaging, products, advertising, and promotions. Headquartered in Portland, Oregon, ICS(r) is a division of Blount International, Inc., a diversified manufacturing company with global distribution. ICS introduced the world’s first concrete chainsaw in 1992 and sells a large line of concrete cutting chainsaws, diamond chains, and related products through a worldwide distribution network.

New Tyrrex for green concrete Cutting of expansion and tension release joints in large areas of newly laid concrete is best carried out when it is barely set, or green, as this has the advantage of minimising crack formation, which is more pronounced if cutting is carried out after the slab has cured. The problem with working on green concrete, however, is that as the sands and aggregates have not set properly into the cement,

slurry and debris in the cut tends to prematurely wear the steel core of the blade, particularly at the point where the diamond coated segments are laser-welded on. Aimed at this market is Tyrolit’s new range of TYRREX high-performance diamond saw blades, which feature redesigned cutting segments and geometry. They are believed to be one of the fastest and most productive saw blades on the market and have peripheral cutting speeds from 50 to 55 m/sec, rather than the more usual 40 to 50 m/ sec. Developed by Tyrolit in Austria, the blades under-

went exhaustive field trials before launch. Low feed pressure is sufficient to complete a cut, resulting in the ability to use lightweight saws, reducing stress on the operator and ensuring clean edges to the cut. Lighter cutting forces also reduce servicing costs. Typical applications are to be found in road and airport construction, for which three blade types are available. Dimensions range from 300 to 450 mm in diameter, 2.8 to 3.9 mm thick. Mounting hole diameter is 25.4 mm and useable height of the diamond segments is 9 mm. Type FSL-G3 is for low power, very fast cutting of concrete that has cured for up to 48 hours and contains medium to very hard aggregates, such as flint. FSM-G3 is a universal, long life blade for use with medium power floor saws, intended for fast cutting of concrete with medium to hard aggregates. FSH-G3 is for the greenest concrete, cured

for 12 hours or less, and is also a long life blade ideal for use with high power machines, suitable for producing sealing joints and widening cuts in concrete containing abrasive aggregates. FSL-G4 is for low power, high speed cutting of concrete with very hard aggregates or steel fibres. The long life FSM-G4 may be used with medium power machines for fast cutting of concrete containing medium to hard aggregates and perhaps also steel fibres. Cutting of expansion joints up to 50 mm deep in industrial floors is another main application, for which two further blade types are available. Any make of electrical/hydraulic or petrol/diesel floor saw might be used with TYRREX diamond saws blades for green concrete, including Tyrolit’s own Hydrostress machines.

second hydraulic lines necessary to run the motor. Italian demolition contractor Lucchini & Artoni used the prototype and results demonstrated that reliability and performance are among the top class equipments in the market. They were using the CP2500R in Milan train station demolishing the foundations with 1.5 m high walls. Afterwards the CP2500R was used to pulverise the concrete and cut and separate the 3035 mm diameter steel. The crusher demonstrated high reliability with more than 400 hours with no problems and downtime.

Russo Recycling goes for DustBoss Russo Recycling is a transfer station in Queens, New York that annually processes about 250 t of solid waste and construction and demolition debris. Previously the company had tried using sprinkler systems and spraying a fire hose to control dust in the transfer yard. The sprinkler system was ineffective and inflexible. The fire hose method was also incapable of controlling dust and also proved to be an expensive method, as it required paying a worker to stand and spray the pile of debris all day long. Neither of these dust control options were effective, used together nor alone. Russo Recycling found the DustBoss® and realized it might be a suitable dust control method. Trials proved the DustBoss was a solution for controlling dust in their transfer yard and there was a noticeable improvement in the air quality at the facility. The amount of moisture deposited by the DustBoss was enough to eliminate dust in the air, but not so much

56

PDi • ISSUE 4 - SEPTEMBER - OCTOBER 2007

that it would over saturate the material in the yard, unlike previous methods. This decrease in water usage not only translated into water savings, but also the material being hauled to the landfill weighed less, resulting in lower fuel costs and less wear-and-tear on heavy equipment. Additionally, Russo experienced savings in manpower hours by no longer using a worker to stand and spray a fire hose over the material all day. “The DustBoss has given a fast return on investment and will pay for itself within 8 months. It has improved dust control in and around the transfer yard and produced a better work environment with less water and no puddles. The DustBoss has helped us keep dust down to zero when moving material on the stacker belts onto the stockpile and are very satisfied with our purchase,” says Russo Recycling station owner Sal Russo.

Trio of excavators help safeguard historic monastery Three JCB excavators have been used in the sensitive demolition of part of an 18th-century German monastery that will see the remaining section given a new lease of life. The JCB 1 t Micro excavator and two 22 t JS220s were used to part-demolish the Monastery of St Anna, in Munich. The 8008 was used to gut 6,000 m2 of the monastery, built in 1725, before the JS machines went in to undertake the heavy demolition work. The flattened part of the monastery will be replaced by 33 luxury apartments under a deal that will see the developer funding essential renovation works on the remaining section. Contractor Trinkl Company has overseen the demolition work, from nearby Krailling. JCB builds 14 micro or mini excavators,

ranging from 800kg to 8 t. Trinkl Company selected the JCB Micro because its compact size allows it to work well in tight spaces. Two variants of the JS220 were used to carry out the heavy demolition work, the JS220LC, with its long carriage, and the

JS220XD, specifically designed to cope with the extreme stresses of demolition, aided by its undercarriage protection and cab caging. The machines are among seven JCBs owned by Trinkl Company. Company owner Florian Trinkl said: ”Our

machines are subjected to around 2,000 operating hours a year. This calls for absolute reliability. We have found an extremely professional partner in JCB and the dealer, Z+P in Ilmendorf.”

Demolishing building sections, pulverising concrete, cleaning iron, smashing foundations, drilling holes for dynamite to blow up bunker ceilings: this represents all part of a day’s work on a construction site where Sandvik machines are deployed.

The old mathematics and physics faculty is currently being demolished right in the middle of Munich-Schwabing, in the university quarter opposite the old Pinakothek. An Egyptian art museum will stand there in future.

Bunkers from second world war The large university quad containing several buildings in Gabelsberger Straße, and on the corner of Barer Straße, is being demolished. Heavily armoured underground air-raid shelters, left over from the Second World War, along both sides of the street, make up the building’s foundations. The demolition specialists from Schreiner & Ottl GmbH from Alling have been contracted to carry out the demolition work. Contractor Thomas Ottl is employing a whole range of Sandvik Rammer demolition machines to demolish the buildings.

Making Room for an Egyptian Museum Using a Sandvik BC2022 steelreinforced concrete cutter (previously the RC22) attached to a Komatsu PC400 hydraulic digger fitted with demolition equipment, digger driver Josef Mayrhofer carefully demolishes the steel-reinforced concrete, bit by bit, from the top. His workmate, Peter Drittenpreis, is helping him with another BC2022 cutter attached to a longfront Fiat Hitachi FH450 digger. The men are making rapid progress with their demolition work. Their comment: ”Sandvik Rammer cutters pinch off pieces quickly and are pretty powerful.” The steel-reinforced concrete that has been broken off is attacked by a Sandvik BP3042 (RB42) concrete pulverizer attached to a Hitachi ZX470 digger. Machinist Gerhard Grillitsch cleanly separates the iron from the concrete. The result: long reinforcement rods clean of concrete. This simplifies recycling and

PDi • ISSUE 4 - SEPTEMBER - OCTOBER 2007

increases the value of the metal junk.

Strict noise requirements The bunker’s reinforced concrete ceilings represent the perfect challenge for the Sandvik BR3890 (G90 City) hydraulic hammer. Digger driver Christian Riedel can use the enormous punching power of the Sandvik hydraulic hammer to break up the chunks of concrete into recycling-friendly sizes to be transported away. The hammer’s well designed plunger and hydraulic construction provides for maximum demolition power, and a diaphragm accumulator permits working for long, unbroken periods in a vertical and horizontal direction. The large, silenced hammer complies with the strictest requirements for noise protection. This permits working for long stretches in urban and residential areas. Improved vibration damping protects the

machinist and the carrier device at the same time. An effective, hydraulic piston brake reduces the effects of poorly targeted strokes, and the simply designed construction makes servicing and operating the machine easy and user-friendly.

7,000 m3 blow up Prior to processing the debris, a Sandvik DX500 drill makes holes in the 3 m thick bunker ceilings and up to 4,8 m high walls to accommodate the dynamite. Afterwards 7,000 m3 metres of solid steel-reinforced concrete are blown up. In total, some 75,000 t of steel-reinforced concrete are being processed on the construction site in Munich. Following completion of the demolition work in the summer of 2007, a film and television college and Egyptian art museum will be built on the site.

AMERICAN O How does the world’s largest manufacturer of hydraulic breaker attachments position itself to take a larger share of the world’s largest demolition market - North America?

“Need to be good teachers as well”

Atlas Copco uses education to make an

Peter Bigwood, president of Atlas Copco Construction Tools, Inc. based in West Springfield, Massachusetts, believes that the basic elements customers want - quality manufacturing, product innovation, and a commitment to responsive customer support - are already in place. Now, they need to be good teachers as well. “We’re confident that our breakers are the best,” says Bigwood. “The challenge for us is communicating that fact to a vast, highly diverse market in which there is no clear leader.” The foundation for this strategy was set in motion in 2004 when Atlas Copco finalized its acquisition of Krupp Berco Bautechnik’s hydraulic attachment division, a move that added medium and large-grade breaker technology to the company’s existing line of small hydraulic hammers. Atlas Copco immediately began pouring resources into expanding capacity, including EUR 20 million in upgrades to its manufacturing facilities in Sweden and Germany and product research and development. While Bigwood says the global trend of smaller hydraulic breakers supplanting hand-held tools is starting to reach North America, the company is putting special emphasis on the upper end of the hydraulic hammer range to serve large-scale demolition and quarrying applications.

Scheduled to make its North American debut at the 2008 CONEXPO in Las Vegas, the HB 10000 can deliver a blow energy of up to 760 t with an impact frequency range of 160 -180 bpm. “If you need a breaker in the 10,000 foot-pound class, you obviously have serious work requirements,” says Bigwood. “Yet few manufacturers offer products of that size, let alone with the features that capitalize on the inherent productivity advantages of hydraulic attachments.” But prospective North American customers do not have to go to such extremes to take advantage of Atlas Copco’s features, most of which are standard across its highly diversified product line. Hydraulic attachments equipment specialist Kevin Loomis points to the HB 2500 as an example, citing built-in “extras” such as automatic lubrication, dust protection, and Atlas Copco’s StartSelect and AutoControl systems, which adjusts the breaker’s pressure to surface conditions. “This helps prevent damage to the breaker and carrier from blank firing, and prolongs the life of internal components,” says Loomis. “Such automatic equipment protection features are particularly important given North America’s growing shortage of experienced operators. Breakers and other demolition tools represent major investments for their owners, so it’s essential that we do what we can to minimize the potential of operator error.” This emphasis on equipment economics also underscores the development of Atlas Copco’s silent demolition tools, such as the line of CC-combi cutters and BP bulk pulverizers. Products such as the CC1700 combi cutter offer various jawsets to help contractors quickly adapt the machines to different materials.


OVERTURES Loomis notes that “reverse construction” - separating and recycling the materials - offers more economic advantages than simply knocking down a structure and dealing with a pile of rubble. “It’s a different mindset, but one that more contractors will have to adopt as environmental regulations become stricter,” he says.

Open channels Other elements of Atlas Copco’s North American strategy stress stronger links to their North American customers. As part of the Krupp acquisition, Atlas Copco assumed sales and distribution responsibilities previously handled by Allied Construction Products, Inc. Bigwood says that having an integrated organization for sales, distribution, parts, and service, “puts us closer to our customers and dealers, and ensures quality throughout the supply and support chain.” In developing its network, Atlas Copco seeks distributors that already offer a rental fleet of excavators, a strong service component, and a willingness to consider a wide range of attachments for their carrier brand. “Perhaps more importantly a prospective Atlas Copco distributor’s management and sales force should be willing to learn as much as they can about breaker technology,” says, hydraulic attachment sales vice president Jeff Malarik. “Hydraulic attachments may represent only a small part of a distributor’s business, but by taking advantage of our ongoing training and support, they can become attachment experts. Responsiveness is also critical, as North American contractors usually want to get started on a job as soon as they have the contract.” So too is helping customers select the right breaker for their needs. Atlas Copco recommends that breakers be selected based on its service weight and the weight class of the attachment’s carrier, rather than the somewhat ambiguous foot-pound class rating system that dates back to the early days of pneumatic breakers. For example, the 2.5 t HB 2500 breaker is designed for use with carriers in the 29 t to 43 t weight class, while the 10 t HB 100000 would be matched to 85 t to 140 t carriers. To compare the impact energy capability of one breaker model of a given service weight to another, Atlas Copco endorses the use of the Tool Energy Rating system developed by the Mounted Breaker Manufacturers Bureau (MBMB) of the Association of Equipment Manufacturers (AEM). Malarik explains that there is too much of a temptation to artificially inflate a product’s capacity using the old foot-pound energy class system because there is no testing to back it up.

“What we would market as a 5000 foot-pound class hammer would actually surpass a competitor’s 7000 foot-pound class product in actual impact energy,” he says. “However, customers still tend to think in terms of energy ratings. Changing that culture will take time, but we feel everyone will benefit if they can compare breakers based on testable, real-world situations.”

Structured for service One issue Atlas Copco’s North American dealers and distributors do not have to worry about is product support. The company recently opened a new service centre in Denver, Colorado, to complement existing facilities in Austin, Texas and Independence, Ohio. All provide complete repair, reconditioning, and maintenance on hydraulic breakers of all types, sizes, and even brands. “Servicing breakers can be a huge headache for distributors and dealers,” says Atlas Copco’s aftermarket sales vice president Matt Cadnum. “They require special machinery and tools, and the component tolerances are very tight. Taking on this responsibility allows them to focus on other important parts of their operations.” Having dedicated breaker service centres also benefits demolition contractors who face ever-increasing pressure to keep their equipment functioning as long as possible. “If a breaker fails on the jobsite, a lot of other, expensive equipment goes idle,” says Cadnum. “We can do repairs on our own breakers in as little as two to three days, including repainting. Depending on parts availability, we can turn around competitors’ breakers in the same amount of time.” And if a part is needed from Atlas Copco’s European factories, Cadnum can have it in the shop or jobsite in just three days. “That’s another advantage of having manufacturing, distribution, and service in the same organization,” he says.

Spreading the conversation While Bigwood reports that Atlas Copco has made some good inroads into the North American demolition market in the three years since acquiring Krupp, achieving its ambitious goal of capturing at least 30% of U.S. and Canadian breaker sales will take time. “In my view, North American buyers want and need Atlas Copco breakers; they just don’t know it yet,” he says. “But it’s not enough to simply tout our products or their benefits. We want to change the way people compare and make decisions about hydraulic attachments. Given the shifting economic and operational trends in the demolition industry, we feel that that everyone -manufacturers, distributors, and users - will only gain by it.”
