How is it out there?

Dear Readers We are now half way through the year that has seen a big decline in business in many markets. Many countries reported a good 2008, but 2009 has been completely different. Here in Sweden some of the contractors and the manufacturers said that 2008 was their best year ever and this year so far is the worst ever. Talk about a quick change round.

Many countries have experienced the recession much sooner then others. Here in Europe I believe Spain was first in followed by the United Kingdom. While other countries still are in recession hopefully Spain and UK are slowly climbing out. But it is strange that this recession came like a thief in the night and struck harder than previous recessions. Here in Sweden, which has suffered a lot from the recession and with an interest rate of only 0.25%, some contractors are just waiting for work while others have plenty of jobs and experiencing an even better economic situation than in 2007 and 2008. This is happening to similar sized companies in more or less the same district. I guess there are many reasons for this. But I believe with fewer projects, same amount of contractors, pricing, marketing and timing can be some of the reasons why some contractors get the jobs while others don’t The feeling is though that many markets have seen some slight improvements during June. The jobs are starting to come back as there is undoubtedly a need as many new housing and infrastructure projects are just waiting to start.

The news and reports in this issue is also a good sign that things are starting to change for the better. Also many manufacturers report growing interest from the market in purchasing new machines and that is a very good and important sign.

In this issue we are publishing information from our associations. The International Association of Concrete Sawers and Drillers recently had their annul meeting.

This time IACDS gathered in Dublin, Ireland. Many topics where discussed and a report of the meeting can be found on pages 52-54. A new President for IACDS was also elected. His name is Peter White and he is well-known in the concrete cutting industry both in the UK and globally. Peter has impressive 44 years of experience in this industry and I am very pleased to welcome him as a regular columnist in PDi under the headline “Word from the President”, which is on this page. I also would like to thank IACDS previous President Pat O’Brien for an outstanding and very valuable editorial contribution to PDi. Pat, who held the IACDS presidency for two periods, is also the executive director for the US concrete sawing and drilling association CSDA, a post he has held for several years. In this position, and as the CSDA is the world’s biggest concrete sawing and drilling association with many foreign members operating on the world’s largest concrete cutting market, I have asked Pat to continue to share his thoughts with us. Pat has kindly agreed and his column “Words from O’Brien” will continue, but more from a US perspective.

Words from the President

Peter White elected new President of IACDS Mr Peter White has been elected new President of IACDS (International Association of Concrete Drillers & Sawers).

And here follows his first editorial column in PDi Magazine: “This is my greatest honour to be elected as president of the IACDS at the annual conference in Dublin, Ireland, June 2009. I would like to thank Pat O’Brien from the USA for his presidency over the last 4 years and his guidance and hard work he put into the association. He will be a hard act to follow. I have been a great supporter of the international association since its first conception and have been to all the meetings.

Over the years I have made some great friends from around the world and have picked up some great ideas on Drilling and Sawing on the working methods and safety. I have also passed these ideas onto the British Association.

I have been in the Drilling and Sawing industry for over 44 years and this step was taken after I completed my apprenticeship as an electrician. I stumbled across diamond drilling and taught myself how to plan jobs and to safely use diamond drilling equipment. I opened my own company in 1967, which grew to be recognised as the UK market leader and operating 10 profit centres with nationwide coverage.

This meant we could deliver a quick and cost affective service to the industry. I am very proud that my daughter Julie White has taken over the company D-Drill, and is carrying the company on into the future, in very difficult times.

27 years ago I went to the USA to the CDSA and received information on how to start a British association. I actually started up the UK drilling and sawing association the DSA to bring all companies together and help set training and standard for the industry. This association is still going strong with 120 members still to this day.

I have been on and off the board throughout the years and I am currently the chairman. I also spent 3 years on the board of the American Association the CSDA, so I feel very proud to have been on the boards of the UK, USA and now the IACDS president.

I would like to say that the IACDS meeting in Dublin went very well and I would like to thank Diamond Innovations for the tour of their diamond manufacturing plant and for their sponsorship, also all the other sponsors.

As we all know in this very difficult economic climate sponsorship is very difficult to come by.

From talking at the

many associations the industry is going through a very difficult time worldwide. All companies involved in contracting and manufacturing have experienced a fall in turnover to the tune of as much as 40% to 75%. The press are now starting to give some positive news on the recession worldwide but it will take some time to filter through the most hit industries such as the construction industry. All contractors worldwide must support the manufacturers who sponsor their trade associations and the world association.

I would like to say that all the entries into the diamond awards 2009 were all of an excellent standard and to congratulate the 4 winners for the great jobs they did and using huge innovation and technology to carry them out. The presentation for the awards was held at the World of Concrete in Las Vegas in February 2009. In my 44 years in the industry, the industry has come a long way and I am amazed at such vast, complicated jobs that we can achieve. We have come along way from the old days when we were not recognised as a trade and now we are recognised as a specialist trade in the construction industry and having a very highly skilled labour force with immense safety awareness.

I look forward to putting my thoughts, feelings and knowledge onto paper every few months for the bi monthly issue of Professional Demolition International (PDi) and hope I can help and pass my experience and knowledge past and present to everyone out there.

P.S. Everyone that went to the IACDS meeting in Dublin enjoyed the trip to the Guinness factory and after their tour drank their free pint of Guinness, one or two had more than one pint. Even the ladies seem to have enjoyed the Guinness.

Best regards Peter White President IACDS

Words from O’Brien

Increasing market sharespecial survey can really work Recently members of the US Concrete Sawing & Drilling Association were challenged to examine how they might be able to increase their sales and marketing efforts in order to increase share and boost annual revenue in a down economic market. The economy is not in the best of shape anywhere in the world and a common tactic is to cut back on expenses in a declining market. The immediate impact for employees is reduced work hours or unemployment as the business owner goes into survival mode to keep the company afloat.

The basic premise of the challenge was that if a company has a certain percentage share of the local market and the market shrinks, then the company’s sales revenue will decline at the same rate as the market.

Rather than assuming that this is just the way it has be and going into survival mode, another approach managers should examine, and one that I recommend since I have marketing background, is to increase sales and marketing efforts to take business from the competition. Just by boosting market share by a few percentage points, it may be possible to maintain the sales level or even increase it depending on how aggressive an approach the contractor pursues. A further benefit comes when the economy recovers and the new higher market share results in significantly increased share of the local market. This can result in a considerable increase in annual revenue.

Feedback from many said this was a good approach, but there were those who said it was a nice concept but difficult to implement. No doubt it is not an easy approach and it takes confidence, but it can be successful. Let me offer a firsthand example of how such an approach can succeed.

CSDA is a co-sponsor of the annual World of Concrete show. There are about

20 co-sponsor associations and in return for attracting attendees to the show, the show organizer rewards the cosponsors for their efforts by splitting a fixed pool of money based on the success of each association’s promotional efforts. In 2009 attendance was 65,287, which was off 23% from 2008 reflecting the difficult economic times. Thanks to a very creative and aggressive marketing campaign, CSDA received a record rebate that was up 32% over the amount received for the WOC 2008. We knew early on that attendance would probably be down and if we did nothing different, our rebate would have been reduced accordingly. However, CSDA implemented an aggressive promotion campaign consisting of email, direct mails and web links to achieve this outstanding success. The approach taken was to gain a larger share of a reduced market.

But this is not the only approach that can work, and contractors should examine their businesses to determine what new approaches can be implemented to boost sales. Many contractors in the past few years have expanded their business to add selective demolition, ground penetrating radar imaging, concrete flatwork, concrete removal and other services to better serve their customer base.

The point should not be that only one approach will work, but rather that contractors should examine their businesses in a down economy and determine what they can do to increase sales rather than just riding out a down economy. I hope you will take this opportunity to examine your business now for a more successful future.

Best regards Patrick O’Brien Executive Director CSDA

A nimble robot from Husqvarna, the right choice for Swiss Anliker

The strength and advanced technology of Husqvarna’s DXR 310 appealed to the Anliker team. From left to right: Othmar von Ah, Husqvarna Sales Manager, Pirmin Derungs, responsible for the department controlled demolition Anliker, Franz Baumeler, Head of operation centre Anliker.

Anliker is a major construction and engineering company located in central Switzerland. When it decided to invest in a new demolition robot, it opted for Husqvarna’s newly launched DXR 310.

Anliker is one of several companies to opt for the DXR 310, the state-of-the-art demolition robot launched by Husqvarna this January. The Husqvarna DXR 310 is of modern design, is packed with new technology and has a really rugged, hardwearing baseplate. It is highly efficient despite its low weight, and offers many smart solutions to facilitate handling and servicing. Anliker already has several demolition robots in its fleet but needed to invest in another one to increase its capacity in the light demolition sector.

An initial demonstration at Husqvarna’s Swiss office really whetted the Anliker team’s appetite. To really get the measure of the new robot, they decided to put it through its paces on one of their construction sites. One of its many jobs was to break up a 380 mm thick concrete floor. Swiss concrete contains flint and is very hard to penetrate.

“We noticed straightaway that the robot had no problem at all with the thick concrete,” says Anliker AG Works Manager Franz Baumeler, .

Anliker then test-ran the robot for another two days before making their decision.

“Several points were decisive. The most important was the machine’s strength and advanced technology, the fact that it is easy to drive, and of course the price was right. We also appreciated Husqvarna’s professional sales team, who had answers to all our questions,” says Franz Baumeler.

The DXR 310 is the first product in a planned series of demolition robots from Husqvarna.

Facts Husqvarna DXR 310 Husqvarna’s remote-controlled demolition robot brings creativity to demolition. It

gives the user significant flexibility in terms of demolition method and solutions for increasing efficiency and profitability. With its compact, manoeuvrable design, the Husqvarna DXR 310 can enter practically anywhere and is perfect for demolition and light excavation work indoors and outdoors. The DXR 310 is ideal for the demolition of building industry materials, as well as demolition of piping, courtyards, stairwells, roofs, balconies, oven linings and much more. It is highly efficient also in sensitive environments.

• High power in relation to weight with good stability and long range • Compact and low-slung construction gives optimal view and manoeuvrability • Cast baseplate assures optimal weight distribution • Simple to service and maintain • Power: 22 kW • Weight: 1900 kg • Range: 5.5 metres • Control system: Modular, digital CAN-based PLC • Support: Included in the standard version • Telescopic arm: Included in the standard version • Dimensions of machine: width 780 mm, length incl. support 2000 mm, height 1030 mm

Concrete Fever in Stockholm, November 2009 Concrete Fever is a forum for knowledge transfer with seminars and workshops taking place at Stockholm International Fairs on 17-19 November 2009, and aims to be the leading concrete fair in northern Europe. In parallel there will also be an exhibition with suppliers of products and services for concrete structures. The primary target groups are architects, the concrete industry, entrepreneurs, real estate owners and supervisors and consultants. Exhibitors will offer concrete related products and services for construction, renovation, concrete cutting, demolition, sawing and drilling. Concrete Fever also welcomes the foreign exhibitors and there will be an area for demonstrating products and services. The exhibition is open for industry visitors and entrance is free. A seminar programme runs over two days, parallel with the exhibition. Visitors will be able to buy single seminar tickets as well as whole seminar packages. The Swedish Concrete Society is responsible for the seminar programme and a party will be held of the first day of the show.

rate of up to 1140bpm, and has the power of 1041 joules at the tip, enabling the machine to tear through the hard rock formation in the tank pit at Park Avenue.

“This is a very important contract for us, and after speaking to Brokk UK, the latest edition to the Brokk range of robots, with this phenomenal power was the only way forward. With this being the first in the UK, it is good to see that in the current economic climate the continued investment in new products from Brokk,” said Lenpart Group representative Sean Siddons, Brokk UK is also pleased to announce the launch of another robot, the Brokk 260, which is a 3.05t machine to complete the 2009 line up of six remotely controlled demolition robots.

Two Brokk 400 delivered to the UK Brokk UK Ltd has sold the first two of the latest Brokk 400 remotely controlled demolition robots to the Lenpart Group for use on a flood defence project in Glasgow, Scotland. A tunnelling and civil engineering company, working for Scottish Water is the main contractor to build a 2,300m3 capacity flood tank in a major flood defence area of the city at Park Avenue, Paisley. Current methods for this type of project would involve 15t machines lowered into the tank to hammer the hard granite rock, with limited production due to the size of the machines. Lenpart Group, incorporating Brokk Hire UK, decided to buy the Brokk 400, which replaces the Brokk 330, to increase production, and allow a safer working environment, as the Brokk is fume free. The Brokk 400 is the largest robot in the Brokk range, and the most powerful demolition robot on the market. The 4.8t machine outbreaks by several times a heavier conventional excavator and is agile and small enough to work in tight spaces. The Atlas Copco SB 552 breaker, coupled to the Brokk 400 combines an impact

Brokk opens AsiaPacific office Brokk AB, world-leading manufacturer of remotely controlled demolition robots, has opened a new office in Singapore, Brokk Asia-Pacific Pte Ltd. The new office will serve as the regional head office for the Asia-Pacific region as well as serving the growing market in Singapore. The Singapore office is the second office in Asia, after a sales office in Beijing, China, opened in 2005.

“The Asian market has grown to be an important part of our business with both India and China among the top-ten countries. With a regional head office in Singapore, Brokk is better positioned to service this growing market,” says Brokk Group managing director Per Waldemarson.

AEM Announces cooperation with bauma China Exhibition The Association of Equipment Manufacturers (AEM) announces international cooperation with the bauma China exhibition. AEM will leverage the global expertise it brought to its CONEXPO Asia show to support bauma China 2010.

“The Chinese market continues to offer vast opportunities for the construction industry and our members. Our support of bauma China is a major component of our global solutions-oriented services targeting the China and Asia marketplace,” stated AEM President Dennis Slater.

“This cooperation is set to give yet another boost to international and especially US-participation by exhibitors and visitors in bauma China in Shanghai”, Eugen Egetenmeir, Deputy Managing Director of Messe München, pointed out.

Earlier this year, AEM also announced a long term cooperative agreement with BICES – the Beijing International Construction Machinery Exhibition and Seminar that also channels AEM’s CONEXPO Asia expertise for the benefit of its exhibitors, members and the industry.

US saw blade manufacturers prevail in antidumping case US based diamond saw blade manufacturers scored a major legal victory in January, with a ruling by the US Court of International Trade that products imported from China and Korea have harmed the domestic industry.

The ruling upholds allegations brought by the Diamond Saw blades Manufacturers Coalition (DMSC), a trade association of domestic producers, that the imported products were being sold at less than fair value, causing undue harm to the US industry. As a result of the ruling, the US Department of Commerce imposed antidumping duties on all Chinese and Korean made saw blades, cores, and segments brought into the US after 23 January 2009.

The outcome is particularly gratifying to the DMSC, given that a 2006 ruling by the US International Trade Commission found no evidence of injury by imported products to domestic manufacturers.

The coalition challenged that decision, providing additional evidence that led the CIT to order the case reconsidered in February 2008.

Three months later, the ITC reversed its earlier decision, ruling in favour of US manufacturers.

“This is only the second time in 30 years of judicial review that the ITC has reversed itself,” says Daniel B. Pickard, a partner in the International Trade Practice of the legal firm Wiley Rein and counsel to the DSMC. “The Court’s decision permits US producers to receive the protection from injurious imports that they have long deserved.”

Overseas blade producers and importers now find themselves in a somewhat awkward position. By appealing the CIT’s ruling to the US Court of Appeals, they will not have to pay the duties until

the appeal runs its course, a process that could take as much as two years. Some of these companies are considering raising prices by all or a portion of the expected duty percentage in the interim, then impounding the additional monies until a final decision is reached.

“If the appeal is successful, the impounded funds would become a windfall profit for the companies appealing the decision, thus helping to defer their legal costs,” says MK Diamond Products Inc vice president and general manager Brian Delahaut. “Should the appeal be denied, however, the ITC could possibly impose the full duties retroactively, costing millions of dollars and potentially putting most of them out of business.”

Delahut adds that the importers are waiting to see if the economy picks up before they make any decisions, given the effect of a price increase in the current construction economy. “We are sitting in limbo at this time with no shift in the status, even though the duties have been imposed,” he says.

Pickard says the chances for a successful appeal by the foreign producers are very slim due to the standard of review used by the Court of Appeals, and the high amount of evidence that demonstrated the injurious impact of Chinese and Korean saw blades.

“The Court gives a wide amount of discretion to the federal agencies, and is extremely deferential to the ITC, which would make it very difficult to overturn the determination,” says Pickard. “In about a year, importers can introduce information in an administrative review in an attempt to adjust the duty amount, but that won’t change the injury decision.”

New Swiss company offering cleaning and protection products to the concrete cutting industry

Mössinger picks up their new Brokk 260

The Swiss company Diamond Services was founded this year to produce cleaning and protection products for the concrete industry.

Construction and building equipment is a high value investment and good quality cleaning and have a direct effect on the performance and life of machines.

Since 2008 DS-Cleaner and DS-Protector have proven to be effective on numerous occasions with diamond and concrete drilling contractors. DS-Cleaner is a ready to use agent free of hydrochloric acid and can remove cement haze, cement and lime deposit and rusting spots. It is safe and treats material with care and makes each treated piece corrosion resistant. Below some pictures showing the results before and after using DS-Cleaner and DS-Protector.

PDi contracts Executive Sales Director for North America

Darren Dunay, Executive Sales Director for PDi Magazine in North America.

Darren Dunay in New Jersey, USA has been contracted as PDi Magazine’s new executive sales director for the North American market. Darren Dunay has been involved with the basic industrial sector in various capacities since 1994. He initially became involved as a trader dealing in non-ferrous metal semi-finished goods for Commonwealth Metal Corp. Then in 1996 he became involved in the publishing side of the business when he joined Metal Bulletin. Initially, his duties involved sales of subscriptions to Metal Bulletin’s and Industrial Minerals journals and research products and also advertising sales in World Mining Equipment. His involvement progressed over time to include taking the role of advertising sales then moving onto sales manager for the Americas for advertising sales in Metal Bulletin while also retaining other duties including overseeing the sales staff for subscriptions and research and also maintaining his involvement in selling advertising in World Mining Equipment even expanding his territory. In 2001 Metal Bulletin acquired the metal publishing titles from Cahners Publishing. These titles included American Metal Market and Scrap Price Bulletin

amongst some other smaller titles. This acquisition left Metal Bulletin plc as the owner not only of the leading international metals publications but also the leading North American provider of metal & steel news and price data. The result was the reorganizing of Metal Bulletin’s Metal, Mining & Minerals publications into a single division.

With the reorganization his duties expanded to a role of commercial manager – Americas. In this role he oversaw all commercial functions including sales (advertising sales, subscription sales, research sales, sponsorship and exhibition sales and conference delegate sales), marketing, circulation, customer service and product research and development in the Americas. While taking on his new role he also maintained his territory selling ads for World Mining Equipment.

He continued in this role continually growing sales in all areas of the division. In 2005 World Mining Equipment was sold thus ending his nine year involvement with the publication where he succeeded taking the worst performing territory and turning it into the titles number one performing territory for ad sales.

In April 2007 Darren left Metal Bulletin to join as a principal partner in a financial services firm, The Basic Industries Group, LLC. At this firm Darren produced conferences on topics covering various basic industrial sectors and helps produce and host a seminar series for the firms clients, which are primarily hedge funds and other financial sector companies.

In 2009 Darren started up Dunay Associates. Dunay Associates is a publisher’s representative business, which represents publishers for advertising sales and other sales and commercial functions in the North American marketplace. Clients of Dunay Associates include publishers involved in various segments of the basic industrial marketplace such as mining, construction and demolition, metal trading, steel production and

trading and cement production and trade.

PDi Magazine welcomes Darren in the team and looks forward in having him as the base for

sales in North America. Darren’s contact info can be found on page 4 and his e-mail address is darren.dunay@pdworld.com.

“Bring us your unemployed”

In the UK the National Federation of Demolition Contractors and PDI’s Mark Anthony have launched demolition-jobs.co.uk, a FREE UK website designed to allow newly redundant and long-term unemployed demolition workers to advertise their skills and qualifications to prospective employers.

As the worldwide economic crisis deepens, demolition workers have started to feel the effects with an increasing number of temporary lay-offs and permanent redundancies. Against this background, the NFDC has joined forces with PDi contributor Mark Anthony to launch www.demolition-jobs.co.uk, a recruitment

NFDC’s Mark Anthony as well as one of PDi’s editors.

website with a difference. “Traditional recruitment websites charge employers to advertise jobs to potential candidates but we wanted to take a different, more altruistic approach,” says Mark Anthony. “We have effectively turned the recruitment process on its head to provide the demolition industry’s unemployed workers with a FREE medium to display their skills, experience and qualifications to prospective employers.”

Mark Anthony reports that the concept of demolition-jobs.co.uk was driven by the fallout from the current recession and by some wise words from a demolition industry veteran; the late Sidney Hunt Snr. “Sidney was one of the most influential figures the UK demolition industry has ever produced. He once described his industry peers as ‘hard bastards, but with a heart’,” he explains. “I have witnessed this first-hand over the years and have seen the NFDC raise countless thousands of pounds for charitable causes. Even in the midst of recession, it is an industry that is unparalleled in its willingness and eagerness to help its own. That really was the inspiration behind demolition-jobs.co.uk.”

NFDC chief executive Howard Button, another driving force behind demolition-jobs.co.uk, says that the time is right for a different approach.

“There is no doubt that the UK demolition industry is on the brink of an unprecedented recession,” he says. “Through the NFDC and the National Demolition Training Group, we have invested heavily in the people that work within this sector.

With our backing of demolition-jobs.co.uk, it is our intention to invest in people that used to work and still want to work in this industry and to safeguard valuable demolition jobs by helping people stay within this vital industry.”

How to deflate a tyre factory In the last few years there has been a severe worldwide shortage of industrial, large-vehicle tyres, exacerbated in part by China’s incredible industrial boom.

Demand has consistently outstripped supply, leading tyre giant Michelin to restructure its global operations and maximize production efficiency to meet the challenge.

Manufacturing at Michelin’s Poitiers factory in France ended in 2007. The emphasis now is on redeveloping the site to create new employment and new commercial opportunities. “It’s a major job,” says demolition contractor Palardy TP representative Stéphane Ayrault. “In all there were 40,000m2 of buildings at ground level.

Most of it was warehousing, but there was one office block, with a basement and two floors. The project lasted five months and by the end we had dealt with over 70,000t of concrete.”

Four Volvo’s on site

Palardy, based in the Sud Vendée region and one of a group of companies involved in the scheme, took responsibility for the demolition of the buildings and the initial concrete crushing. The company had four demolition excavators on site, three of them Volvo. The biggest was a 46t EC460CLD, with a 6t pulverizing attachment. There are also two EC360s, one a standard machine and the other capable of being equipped with a high-reach boom configuration.

“We first looked at Volvo machines two years ago,” says Ayrault. “Our equipment was getting old and needed upgrading so we tested one. Now we have six Volvo excavators and one wheel loader. We used to have a wide variety of machine brands, but now they are mainly Volvo or Hitachi. We’ll be sticking with them in future.”

Things have changed

Not so long ago, demolition sites were characterized by noise, dust, dirt and the archetypal wrecking balls swung from cranes. “But the industry has been transformed in recent years and is continuing to evolve rapidly,” explains Ayrault. “Modern demolition sites are nothing like the battle zones of yesteryear. It’s not like the wild old days. On the contrary, demolition sites are very clean and not really very different from your average construction site.

“Everything is very controlled and done in stages. The new Volvo engines make a lot less noise and consume less fuel. There’s no comparison to the

vehicles we had before. And for the operators in the cab, there’s the extra comfort of the seating and the space and the layout. It’s simply a much more pleasant environment to work in, which is good for everyone. You work better in better conditions; it’s that simple.

“The first phase of work was to clear out and clean the buildings. A lot of that is done manually or with small machines.

Then there is what is called selective deconstruction before the big excavators are brought in”.

“There is a huge emphasis nowadays on recycling and on the environment. Everything that can be recycled we recycle. There’s not just the concrete, which is crushed and then reused in civil engineering projects. There are also companies which specialize in re-using wood and plaster and other materials.”

Playing it safe

Ayrault says that demolition work is not nearly as dangerous as some people imagine. Wrecking balls have been replaced by careful planning and sophisticated step-by-step demolition. Safety is a paramount concern, an emphasis that has also highlighted the Volvos’ advantages. “With our range of attachments, like grapples, concrete pulverisers, clearing rakes and metal shears, we can do pretty much everything nowadays,” says Ayraul.

The Poitiers project has gone well for Palardy. “It’s a big site so there was plenty of space to operate in. We’ve needed big machines but there were no real complications. There have, of course, been some breakdowns, there always are with machines in this demanding line of work, but they have all been minor and there are Volvo service agencies everywhere so things have been sorted out quickly,” says Ayrault.

As the head of Palardy’s demolition section, Ayrault, stresses he is better at evaluating projects and finalizing contracts than working out in the field. “I’m not sure anybody would be too impressed with my skills as an excavator operator,” he says. In fact Ayrault’s career has turned full circle. He used to build things. Now he tears them down. “I suppose you could put it that way,” he says.

“I began my career in construction and I’m now in the demolition business. There’s no special emotion when you demolish buildings.

Mostly, they’re industrial units in a bad state of disrepair. It might feel a bit different if I had to demolish something which I helped build, and perhaps that will happen eventually. When I’m about 60, hopefully not before!”

The Universal Lang Despite the economic

downturn that has impacted on the demolition sector across the world, John Woodward remains a man in demand, as PDi’s Mark

John Woodward is not a typical demolition man. While denim is considered de rigour in the demolition industry, Woodward is more likely to be found in a suit as sharp as a diamond drill accompanied by a tie as loud as any implosion.

While his contemporaries eschew any technology that does not involve hydraulics, Woodward is very much a man of the computer age. And while his peers can trace their demolition lineage back through many years and generations, Woodward is something of a newcomer with just a decade of demolition life under his belt.

Man in Demand But none of this has stopped Woodward from climbing to the very upper echelons of the UK demolition industry; and neither has it detracted from his success in business. Recently elected vice president of the

Anthony reports.

Institute of Demolition Engineers and collecting an Institute Fellowship along the way, Woodward is a man in demand; indeed, he was recently called upon to consult with a leading theatre director on demolition terminology for a forthcoming London play.

I met him at an Indian restaurant, far away from the specialist training room of his company C&D Consultancy; far away from the sites on which he consults or acts as a mediator between client and contractor; and far away from the offices of the Institute and the other significant draws on his time. Despite this neutral territory, Woodward’s cell phone rang continually, requiring him to offer advice and guidance long into the night.

On the plus side, this did allow me to occasionally avert my gaze from his tie, which was threatening to spontaneously combust my optical nerves.

Woodward’s rise to the top of the demolition industry is all the more remarkable given that he has been active in the business for just over 10 years; and the fact that he came to the sector as much by chance as by design. A formally trained civil engineer (and a jobbing DJ; but that’s another story), in 1997 Woodward accepted a two-week secondment to a demolition project run

by Danny Doyle, former president of the National Federation of Demolition Contractors. “After two weeks, I was hooked,” Woodward says. “Previously I had worked for the world’s largest swimming pool company, overseeing multi-million pound contracts so I was used to tight deadlines and having to think on my feet. But demolition just got under my skin.”

In typically nomadic style, Woodward moved around within the demolition world, working for a number of UK contractors, honing his skills, before finally arriving as a director of a now defunct company called Loxley Dismantling Ltd based in Wakefield, far from his home in the Midlands. “Loxley was owned by a larger company and I could sense that they weren’t keen on retaining a presence in the demolition field,” Woodward recalls. “At the same time, I had grown tired of being away from home so I handed in my notice.

On the day I left, the company went into liquidation, so my decision was justified.”

Going it Alone Woodward was now faced with a dilemma. An enthusiastic learner, he had been a long-time student of the art of demolition. During his time working with some of the UK’s best known contractors, Woodward had secured a raft of industry qualifications, starting as a “Topman”, moving on to supervisor and ultimately to demolition manager. “I was not and never have been a professional student,” Woodward explains.

“But I have always believed that you should never ask anyone to do what you can’t do yourself. And if you are going to tell someone what to do, you have to be at least as well qualified as they are, and ideally better qualified.”

Demolition Consultant Unemployed after the Loxley Demolition debacle, Woodward set himself up as a demolition consultant, advising a select band of friends and clients and writing method statements for them. His service proved popular and set his company, C&D Consultancy, on a growth path of

guage of Demolition year on year doubling of turnover that continues to this day.

Perhaps not surprisingly, given his unstinting belief in education and learning, Woodward has long since expanded C&Dâ&#x20AC;&#x2122;s product offering to include a multitude of training courses in which he is able to instil his experience into other demolition workers.

But, not content with passing on his wisdom to UK contractors and workers, Woodward is planning to export his knowledge to other parts of the world through innovative and pioneering online training initiatives. â&#x20AC;&#x153;I firmly believe that the UK standard for demolition training is the best in the world,â&#x20AC;? he asserts. â&#x20AC;&#x153;Having already worked in both Spain and Italy, I am now determined to provide overseas workers with access to our standard of training.â&#x20AC;?

be able to log on, view and interact with the recorded presentation. They will then be emailed a questionnaire based upon the presentation, and they will be given 20 minutes in which to complete it.â&#x20AC;?

Woodward admits that his scheme faces some challenges.

There will be initial issues around ID clarification and, of course, the ever-present issue of the language barrier. But Woodward remains undaunted. â&#x20AC;&#x153;A high reach machine is the same in any language. Asbestos looks the same wherever you are,â&#x20AC;? he insists. â&#x20AC;&#x153;Demolition is a universal language and we cannot allow something as minor as language to stand between us and a safer, more competent workforce. I donâ&#x20AC;&#x2122;t care where they are. If a company needs my help, I will provide it.â&#x20AC;?

Online Presence

John Woodward holds similarly international ambitions for the Institute of Demolition Engineers. Having recently explained the benefits of IDE membership to the European Demolition Association in Istanbul, Woodward and current IDE president Terry Quarmby are actively seeking stronger links with other demolition bodies across Europe and beyond. â&#x20AC;&#x153;The Institute of Demolition Engineers is the only recognised professional body for demolition engineers in the world. We already have members as far afield as the US and Australia,â&#x20AC;? John Woodward concludes. â&#x20AC;&#x153;But we are constantly looking for more. And if that means that Terry and I have to go to Sweden, Poland, the US or anywhere else for that matter, then thatâ&#x20AC;&#x2122;s precisely what we will do.â&#x20AC;?

Unlike many of his peers who still believe the Web is something created by a spider, Woodward believes that the solution to the problem of delivering UK standard training economically to overseas locations lies online. A keen advocate of the Internet â&#x20AC;&#x201C; his own personal website, www.demolishdismantle. co.uk is updated almost daily, and he has recently joined the online micro-blog Twitter and can be followed at www.twitter.com/johnwoodward â&#x20AC;&#x201C; Woodward is planning a series of online seminars and distance learning study groups that will be available to workers across Europe and beyond. â&#x20AC;&#x153;I am in the process of recording a series of online teaching broadcasts which we will make available online,â&#x20AC;? he says. â&#x20AC;&#x153;Students will

JCB enters portable lighting tower market

Demolition contractor buys Bobcat In Scotland A C Jardine Demolitions Limited has purchased a Bobcat compact loader and a pair of excavators from Motherwell-based George Colliar Ltd trading as Bobcat Strathclyde, to meet the requirements of demolition and refurbishment contracts in the country’s capital city Edinburgh.

The machines are a Bobcat S100 skid-steer loader, a 323 mini-excavator and a 442 7.5 tonne midi-excavator, all supplied with a variety of implements such as 4-in-1 bucket, hydraulic breaker and demolition grab attachments.

“Our purchases followed an exhaustive investigation of the equipment available on the market,” said A C Jardine Demolitions owner Cunningham Thomson. “The Bobcat equipment was chosen for the high quality of engineering involved, along with the robustness of the machinery; which are definite requirements for our industry, together with the wide variety of specialist tools available. They also meet our goal of increasing the mechanisation of demolition work inside buildings or in confined spaces to meet health and safety requirements for our staff and to improve the efficiency of operations.”

The company carries out all types of demolition, site clearance, dismantling, shoring, structural work and recycling and specialises in projects with

significant logistical or access problems.

Mr Thomson said: “A lot of the buildings we work on are under seven storeys high and are completely surrounded on all sides by other properties, so we have to overcome a high degree of difficulty and site restrictions when carrying out demolition work and the compact equipment from Bobcat provides the best solution,” said Cunningham Thomson. “For example, the 442 is one of only a few machines that can gain access through the confined narrow passages at the base of these buildings, which quite often form the only acceptable route to the worksite.”

The Bobcat S100 skid-steer loader and 323 mini-excavator have been utilised in the redevelopment of the old Leith Academy Building, where they were used for internal demolition work to remove soft materials such as timber, doors and partitions as well as concrete and brickwork from the site.

“Prior to the purchase of the new Bobcat machines, we had always been delighted with the quality and performance of the Bobcat equipment we had hired over several years from Bobcat Strathclyde, together with the high standard of service they provide,” added Cunningham Thomson.

JCB Power Products is entering the portable lighting tower market with the 9m JCB LT9. It is a dedicated lighting tower with a hydraulically activated, telescopic mast supporting four spotlights, each delivering 1000 watts and 90,000 lumens, giving a total output of 360,000 lumens.

Mounted on a compact integrated chassis, the LT9 is transportable, making it ideal for rental fleets. It will provide temporary, portable lighting to a vast range of applications.

The LT9 is simple and quick to use, with the mast activated by a button on the side of the model being fully erected in 13 seconds.

It can rotate 360° to provide excellent lighting capability to all areas of a site.

The unit is fully homologated for highway use and to further improve manoeuvrability it also features forklift pockets and a single-point lift eye as standard. Available globally, these new lighting tower products will be sold and supported through JCB’s extensive worldwide network of dealers.

All about braxx

Concrete drilling and sawing companies keep their machinery closely in line with requirements so that the business activities can be performed precisely but without tying up capital. For this situation, EDT Eurodima provides the ideal product programme as the modular product range allows maximum flexibility. Based on the control braxx control units, which are made for the power range from 20 to 32kW, concrete sawing contractors can choose the appropriate drill motor. Combined with the wall saw head, rails, blade guard and accessories, the wall saw is capable of using diamond saw blades with diameters up to 2m.

“Interview with Europe’s best concrete cutter”

Braxx as wire saw In addition to the wall saw function, the braxx unit can be used as a wire saw, as a WB6 wire saw appliance with 6+2 m wire storage, an electro pneumatic WB12wire saw machine with 12+4 m wire storage, or even as a CB350circular saw.

It is also possible to use the control unit as a drive for hydraulic wall saws

Duramant from EDT Eurodima Complex as well as small and easy tasks are accomplished in a precise and reliable way. EDT Eurodima offers the complementary tools from Duramant, which provides higher tool life and cutting speed through its novel type of diamond segment bonding. In addition, Precision Tension Guarantee assures the perfect tensioning of the saw blade, producing clean cuts.

Braxx in real life The advantages of the combination of braxx and Duramant can be seen in all sizes of projects.

The sb200 typhoon wall saw showed its qualities at the new accident and emergency department at the Saale Unstrut Klinikum clinical centre in Naumburg, Germany. There EDT Eurodima customer, Gerd Beyer GmbH & Co KG (Laucha), was charged with the concrete sawing and drilling tasks. After placing the concrete floor screed, it was found that the down stand beam in the corridor overlapped by 100 mm into the ceiling and had to be cut at three different points.

The beam was 300mm wide, 2.8m long and reinforced with two 18 mm diameter full length

bars, and 16 mm diameter bars at 50 mm intervals on both sides.

For the task, the small high frequency sb200 typhoon saw with 20 kW power and a cutting speed of 2 to 60m/sec was chosen.

The diamond saw blade was 800mm diameter with Duramant fast-cutting WS15 segments.

Cutting took only 20 minutes and the customer was highly satisfied with the characteristics of the sb200 typhoon and Duramant diamond segments.

Below is an interview with the champion of Tyrolit Cutting Pro Competition 2009.

twelfth place after first discipline. “It isn’t over until the fat lady sings” proverb proved to be right this time.

Q1: How did you prepare yourself for the European Championship?

I really didn’t do anything special to prepare myself.

I just used these machines at work prior to this competition as I always have. During the competition I just wanted to go out on the stage and do my best.

I was quite relaxed about it.

Q7: What was it like to cut and saw in front of 600 people?

It was an awesome experience. To hear all those people cheer and support you was great. My friend and I have a band and we play our music to crowds.

Performing gives me an adrenalin kick. It was a little bit like that during the Cutting Pro Competition.

Q2: Did you consider you would be the winner?

I have always been a competitor. I was a boxer in my younger days and this sport taught me to always go after the first place. Winning is more fun and so it was in Innsbruck. I always thought that second place was just for the first loser.

Q8: Has the victory changed your job? Have you or your company benefited from the victory? In what way?

Not really. I still try to do my job as well as I can.

The customers though have been very positive and supportive. They call my boss to send the European Champ out to them to do the job, which is quite funny.

The company has received a lot of good publicity out of this competition through local TV and newspapers, which has been very positive. Our company has always had a very good reputation and this result has just helped to make it stronger. My boss is quite happy about that.

Q3: What are the skills that made you win the Championship?

I could relax during the competition, even when I was far behind after the first and second disciplines.

All the competitors were professionals, so maybe it was my nerves or the control of them that made me the Champ.

Q4: How did your daily work contribute to this victory? Were you familiar with the machines from daily work?

I have been working with cutting and drilling for the past 10 years, so I suppose my daily experience has helped quite a bit. I knew some of the machines quite well.

Q5: Did your boss support your participation? If so, how?

My boss has supported me 100 %. He has been very excited about this event, maybe even more excited than me. He also came down to Innsbruck with his wife to support me. It really meant a lot.

Q6: How did you cope with the pressure?

Q9: What do your family and friends say about you being the European Champion?

My wife Lisa was with me in Innsbruck, so she saw the whole event. She was very supportive as she always is. My kids were quite proud of their father after they heard I won. I have really got some good feedback from my family and friends and they think it was kind of cool, that I got the trophy.

Q10: You set a benchmark for future participants in the Cutting Pro Competition.

How will you prepare yourself for future championships?

I will probably prepare myself in the same way as I did this time, only next time I will cut and drill faster.

I would also use this opportunity to thank the whole Tyrolit team for the well-organized event. It was a very good experience. Everyone was so friendly and helpful. I can’t wait to be part of this event again.

Bobcat’s breaker developments Bobcat’s HB880, 980 and 1180 80 Series breakers are now approved for use on the new E55W wheeled and E60 crawler excavators.

All the breakers can be mounted using the pin-on, Klac or Lehnhoff systems, three of the four mounting systems currently available from Bobcat.

At the other end of the Bobcat excavator and breaker ranges, the smallest HB280 breaker, now has the modular fixing cap system used in the rest of the 80 series and, can be used on the 316 and the new E08 and E10 micro-excavators that have superseded the 316 model.

The HB880 has an operating weight of 232kg, works with flow rates from 30-65l/min and provides a blow rate from 755-1150bpm for work on soft ground and a blow rate of 860-1310 bpm when working on hard ground.

With an operating weight of 268kg, the HB980 breaker has blow rates of 855-1060 and 11701450 bpm, respectively, and is designed for a hydraulic flow range of 45-80l/min. The blow rates in the 1180 model are 680-1070bpm for soft ground and 820-1280bpm for hard ground. This breaker has an operating weight of 386kg and works with flow rates from 55100l/min. With a flow requirement of 13-23 l/ min, the 65 kg HB280 breaker has blow rate of 600-1450 bpm.

The 80 Series pioneers a completely new way of working with a breaker. For the first time either a bucket or a vibrating plate accessory can easily and quickly be fitted onto the breakers.

The 80 Series hydraulic breakers are designed for trenching, concrete demolition and general excavation work and feature a frame with a cylindrical design for better access to jobs in confined areas. The breakers are standard equipped with a special shield to protect hoses and fittings from being damaged when working close to the ground or in tight spots.

The innovative design of the breaker hydraulic system provides increased efficiency and incorporates a very effective soundproofing system. In addition the breakers have fewer moving parts and no tie rods and can be completely dismantled in less than five minutes, without the need for special tooling.

Atlas Copco’s new SB 452 breaker Atlas Copco has added the SB 452 breaker, the seventh model in its solid body light breaker range. The SB 452, for use with excavators up to 13t, offers the highest performance and breaking power in its class thanks to a new hydraulic system that delivers higher efficiency and improved energy recovery.

The slim design of the SB 452 makes positioning easy. The compact dimensions also make it easy to work in confined applications such as indoor demolition work, along house walls and in narrow trenching. It can also be used for general demolition, roadwork, trenching and landscaping.

Atlas Copco’s solid body breakers are recognized for their durability and reliability.

“A solid body breaker is machined from a single block of steel. This method provides a number of benefits, such as no side or head bolts and a unique resistance to bending forces and operator abuse. Another advantage is fewer parts and less maintenance,” says product line manager Thord Wikström. “One of the most important features in the new design is the floating bushing, which makes service and maintenance really easy. The new SB 452 brings many advantages.

The single blow impact energy has increased by more than 12% compared to the previous model, which results in higher performance and breaking power. And the new body design

generates lower vibrations and less noise to meet the high demand of our customers.”

...And the new HB 3600 breaker The new HB 3600 breaker from Atlas Copco fits the 35-63t carrier weight class. It delivers 46% more performance per kilogram service weight compared to the average of other hydraulic breakers in this class. And compared to competitive products of equivalent weight, the HB 3600 offers a 30% higher efficiency, the company claims.

Since the carrier weight classes have become more precise and divided into sub-classes, attachment providers tend to comply with this trend. With its new heavy-duty hydraulic breaker, Atlas Copco keeps pace, and presents a tool for the perfect fit.

Avoiding improper adjustments of carrier and attachment, the HB 3600 offers the best weight/performance ratio of its class. This means that similar results can be obtained with lower breaker weight, requiring a smaller

PDi • Issue 2 - 2009 • May-June

excavator. Investment cost and cost of ownership decrease.

Thanks to energy recovery it is possible to exceed a 100 % output without increasing the hydraulic input during peak periods. Constant impact energy is able to increase blow frequency and therefore boost percussive performance.

The HB 3600 comes with established features, such as PowerAdapt, StartSelect and AutoControl, ContiLube© II, DustProtector II and VibroSilenced. The original ProCare™ service contract completes a power package that simply fits any requirement.

Bobcat’s New Steel Tracked Loaders Bobcat has launched new steel tracked versions of the T250, T300 and T320, compact tracked loader range as an alternative to the conventional rubber tracked configurations.

The steel-tracked versions of the Bobcat compact tracked loaders are claimed to be unique due to their ability to work with over 40 different attachments in a wide variety of applications. They offer very versatile alternatives to dedicated crawler dozers, which can only be used for bulldozing applications. With a 1.87m, all three machines have a better turning ability than larger tracked machines.

The steel tracks, which are 340 mm wide, offer up to three times the track life of rubber tracks in heavy-duty applications. Compared to the rubber tracked versions, the steel tracked T250, T300 and T320 models have an increase in operating weight of approximately 280kg each and provide a 37-45% increase in pushing force across all three models.

In addition to excellent traction, the steel tracked machines offer high digging power and good dozing and grading capabilities. The machines are ideal for work in general construction and rocky conditions, site development and rock blasting areas.

The sealed and lubricated track chain has a 50% reduction in internal bushing wear, a quieter operation and lower fuel consumption than the sealed only chain. The lubrication also reduces resistance compared to the sealed only chain. Other aspects include triple grouser track shoes for a smoother ride and the 340mm wide pads provide a good balance between traction and flotation. The angled top plates offer easy cleanout, with an open area around the sprocket and under the top roller.

High quality attend With by far the most severe worldwide economic downturn since World War II, there were big worries, not the least from the organizers, that the most important construction trade show this year, Intermat 2009 in Paris, was going to be a disappointment for many exhibitors and visitors.

Maybe so for some, but hindsight indicates that worries were quite exaggerated.

Text & Photos: Mikael Karlsson

With a total of 184,518 visitors (209,000 in 2006) to the exhibition over the six days and 1,470 international exhibitors (1,320 in 2006), some visitors even said that this Intermat was the best ever.

Good news flow A reason for that is that without the record numbers we have been getting used to after every event like this, still lots of people came to the show. And they could see what they wanted to see in a more relaxed way with less congestion than what we are normally used to when the fairs are growing bigger and bigger on every occasion.

When it comes to the areas of demolition, it is a fact that many of the big, well-known manufacturers and especially of concrete cutting equipment, were not present due to budget restrains. Despite that the show offered many new interesting machines and tools for demolition applications.

All major manufacturers of hydraulic excavators see the potential in demolition and all of them now offer machines and tools for such applications.

New Holland

Case presented the new high reach demolition excavator CX470B HRD. The machine offers a 27.1m height, has a reach of 14.2m and can carry a tool weighing a maximum of 3t.

New Holland, for example, presented for the first time a full line of machines for the demolition industry, represented by the E385B Demolition, E245B Demolition Multifunction and the brand new 21t E215B Demolition version of crawler excavators.

The new model is designed for ground-level clearing up and breaking duties and to work alongside the long reach machines and features additional protection for safe demolition work. It is fitted with cab guards, full-length track guides, arm protection, cylinder protection, undercarriage and bodyguards and side impact protections.

of high reach and digging. A hydraulic quick-change mechanism makes is possible to switch to a standard earthmoving boom in about an hour, according to the company.

Caterpillar Caterpillar launched the 328D medium size hydraulic excavator, which it claims is the first compact radius excavator specially equipped for demolition in urban or restricted areas.

The machine has been designed and prepared for demolition purposes in collaboration with the French Caterpillar dealer, Bergerat Monnoyeur.

The concept of the 328D for demolition is simple. The standard reach boom of 6.15m was modified to allow two positions. The boom cylinders can now be mounted either underneath or in the normal guide. Thanks to the boom cylinders, the 328D can work with the demolition stick or the normal stick. A change from one stick to another is simple thanks to a quick release. This adds to the versatility of the 328D, which can also be equipped with a blade.

In order to offer the maximum working height Bergerat Monnoyeur designed and built a special stick of 5m enabling a maximum reach of up to 14m. In this configuration the excavator can carry a hydraulic quick coupler CW45 and a multi processor MP20.

Hitachi Hitachi presented four new models, the ZX250LCH-3, ZX350LCH-3, ZX470LCH-3 and ZX870LCH-3. To illustrate the versatility of its factory-modified machines the company exhibited the ZX470LCH-3 demolition excavator with 27m

high-reach boom. All demolition models, from the ZX250LC-3 to ZX870LCH-3, can be ordered with various high-reach, twopiece and standard booms, and can be customised at the factory at Oosterhout in The Netherlands. This multi-boom principle gives Hitachi customers greater flexibility with finance and the versatility to work on a greater number of demolition projects.

Hitachi says it will widen its demolition range over the next five years with higher-reach machines and hydraulic undercarriages to appeal specifically to the European market

Volvo Volvo launched the EC360CHR ultra high reach demolition excavator with 21m reach. Some key features of the new machines are a hydraulic modular joint that enables a 30 minute quick change from demolition to standard backhoe attachment, aiding high machine utilisation when not required for high reach projects.

Volvo’s ultra high reach machines come with both demolition and digging boom and arm, with transportation cradles for both standard, hydraulically tilting cab with up to 30º degree tilt to enhance operator visibility when working at height and reduce fatigue and neck strain on high reach jobs.

The machine has an optional, extendable undercarriage that expands by 1m to ensure a more stable working platform and a 360º working radius. The EC360CHR will be followed shortly by the launch of the 27m reach EC460CHR.

Doosan Doosan from South Korea presented a new demolition excavator based on its 34t DX 340 tracked machine adapted for European demands. Features include a three-piece boom, tilting cab and hydraulically extended undercarriage. The hydraulically variable undercarriage is 2.99m when fully retracted for transport and 4.1m when fully expanded for operation. A 2t attachment can be used at a height of 22m, enabling the demolition of a wide variety of buildings in urban settings.

The hydraulic system of the DX340 demolition excavator is designed to allow the use of several different attachments, making the machine ideal for a wide variety of applications.

Sennebogen The German manufacturer of special cranes and material handling machines, Sennebogen, officially launched the 830 R-HD Special of the D Series for demolition applications. “Like most other brands of demolition machines, this is not a modified civil engineering machine, but a robust machine especially designed for extreme demolition and material handling jobs featuring some different technical solutions,” said marketing and corpoIssue 2 - 2009 • May - June •

Another standard feature, which is unique on the market, is the tilting maXcab comfort cabin, which can be raised to 4m for safe working and a perfect overview. The Sennebogen 830 D Series can also be equipped with a grab or dipper shovel and used as a fully functioning material handling machine.

Brokk AB Indeco’s Marketing Manager, Michele Vitulano.

The Swedish manufacturer of remote controlled demolition machines, Brokk AB, has had a very active last 12 months. The company has launched two new models, Brokk 400, which is their current largest model, and Brokk 260. Both products have been well presented in previous issues of PDi. Brokk reported a great interest for their new models at Intermat and several machines of the new models has already been delivered.

Indeco

Ramtec highlighted the newest of its patented crusher grapples, Robi CG35 r, which comes in between the CG20 and CG50 model, aimed for 20 to 40t excavators.

Many Italian demolition attachment manufacturers were present at Intermat.

“We are presenting our new smallest rotating pulveriser for 10-20t excavators. And also a new bigger model in multisystem, Multi 1250, which is designed to meet the demands of the American market, where larger tools are more in demand,” said Indeco marketing manager, Michele Vitulano. He also added that Indeco currently offers the world’s biggest hydraulic breaker, the HP 18000 and five have been sold throughout Europe and the US.

Meccanica Breganzese

Caterpillar launched the 328D medium size hydraulic excavator, which it claims is the first compact radius excavator specially equipped for demolition in urban or restricted areas.

Meccanica Breganzese produced the very first bucket crusher in the world and manufactures a range of four basic models. At Intermat the company also launched the BF 90.3, with more capacity, strength, resistance and balance and is also compact to enhance productivity.

Promove Promove chose Intermat to present two new hydraulic breakers. The XP300 will fill the gap in the compact range, and the giant XP7000 for heavy breaking in quarrying and other severe applications.

The XP300, equipped with a 80mm chisel, is designed to work with 5 to 6t excavators and a range of skid-steer loaders.

It has an anti blank-firing system, square-section percussion body and vibration and noise insulation for operating under the strictest urban regulations. The bigger XP7000 features the combined gas and oil working principle, blank-firing prevention system, auto-greasing pump, adjustable frequency/energy, full square-section percussion body and high back pressure. An underwater operation and tunnelling kit is optional.

to 130t excavators. The tool weighs 11t and has a height of 4m and jaw opening of 2m and is ideal for primary demolition.

Its twin pin jaw design ensures even crushing force through the jaw. And its twin hydraulic cylinders are fully protected while the tool is in use.

Allu Finland is another active nation for making attachments and machines for the demolition industry. ALLU launched the new D-series of the Fine Fragment Screening bucket, which includes 12 different models that can be mounted on excavators and wheel loaders. It is also possible to mount the attachment to an excavator as a shovel or pick. The dual adaptor mounting allows the bucket to be mounted in either position depending on site conditions. The horizontally mounted drums make the processing of different materials more efficient. You can also choose whether to use 15 Disc in Disc design to produce 0 - 15mm end products, or 25 DiDP drums producing 0 - 25mm end products.

Ramtec Ramtec highlighted the newest of its patented crusher grapples, the Robi CG35 r, which comes in between the CG20 and CG50 model, for 20 to 40t excavators. All three sizes are easily adaptable where crushing, pulverising, handling and loading are required. They can easily be used for each kind of application by changing the jaw tool. Hydraulic rotation is standard on all models. “We have already sold 15 of this model in Finland and one to Estonia with very good results and satisfied customers,” said Robi sales manager Vesa Santala.

Avant Tecno Caterpillar Work Tools launched a new line of concrete crushers for hydraulic excavators, including the P300-series.

Faster, safer and less dusty with Tyrolit Austrian manufacturer Tyrolit released two new product series earlier this year that is strongly beneficial for the professional concrete cutters. The new TYROLIT DCU*** Fastcut 4in1 diamond saw cuts quickly, is ideal for the cutting of steel and thanks to its robust design has a long tool life. The new lightweight TYROLIT Premium *** DDL dry-drill bit requires very little pressure and reduces dust formation and drilling times.

Segment: Significant time savings and incredibly robust The new TYROLIT DCU***-FC 4in1 dry-cutting diamond saw is ideal for the cutting of concrete, hard stone, steel and abrasive materials. It is available in diameters ranging from 115 to 230 mm. The segment is characterised by an optimised bond system and uses diamonds of the highest quality. The blade is manufactured using optimised HDS ® technology (High Density Sintered) and has a compact bonding structure, very good bonding of the diamond grain and a high degree of safety thanks to the excellent connection with the steel blade.

The turbo layer gives the TYROLIT DCU***-FC 4in1 dry-cutting diamond saw an exceptionally high stock removal performance and consequently saves a great deal of time. The increased segment size,10 or 12 mm including the neutral zone, and the short tooth segmentation make the TYROLIT DCU***-FC 4in1 dry-cutting diamond saw extremely robust yet have no adverse effect on its long tool life.

Steel blade: Absolutely smooth running and a straight cut To ensure the saw blade does not crack, even under high loads, the notches have drop-shaped perforations and are shot-peened. This special type of perforation reduces the force effect on the steel blade. To provide maximum stability, all blades are made from hardened steel and tensioned using a rolling trace. The result – absolutely smooth running, producing a straight cut and neat cut edges.

New body equals no tilting The new TYROLIT Premium *** DDL dry drill bit is the ideal tool for the installation of sockets and junction

boxes and smaller breakthrough jobs. A patented manufacturing process means the segments are now only 3 mm instead of 4 mm wide. This has allowed the size of the body and the weight of the drill to be reduced.

The advantages of this innovation are obvious: the drill bit is much lighter than conventional bits. The thinner segments and thinner body mean less stock has to be removed. Not only is less pressure required, considerably less dust is generated. However, the real clincher is the extremely short drilling time.

Locating the dust openings in the cover of the drill bit is another significant advantage compared with its predecessor. On the earlier model, these openings were situated on the side of the body, which meant the drill bit could tilt over. The fact that the openings are now integrated into the cover ensures that tilting is a thing of the past with the new TYROLIT Premium*** DDL dry-drill bit.

If required, a suction hood can also be fitted to the cover to allow an industrial suction unit to be attached and every last trace of dust to be removed.

The result – no more time-consuming rework and

Promove also launched the smaller XP300 to fill the gap in the compact range.

The Japanese demolition tool manufacturer NPK used Intermat to unveil the new concrete cruncher, G-17 J, and scrap shears, K-3J and K-33 XR, for the European market.

The G-series crunchers are designed to reduce oversized concrete pieces at ground level after they have been demolished.

Simultaneously the reinforced steel will be separated from the concrete on site. “The G-17J cruncher has the same technical features as the others in the G series, but is a little smaller than the G-18J and more adapted for European site applications,” said NPK Holding B.V. executive director Naoki Watanabe, based in Rotterdam.

The new P300-series of multi-functional concrete crusher for hydraulic excavators extends the range of hydro-mechanical work tools. Because this equipment substantially limits the amount of vibration and noise it is well suited for concrete demolition in residential areas. The hydraulic concrete crusher combines several concrete demolition operations in one piece of equipment: for example: breaking out concrete from fixed structures, pulverizing concrete and cutting reinforcement rods and small steel profiles.

Caterpillar Work tools also presented the new S300B scrap shear series at Intermat. The S320B, S325B and 340B series fit Cat excavators weighing from 10t over 60t.

Hilti takes a few easy steps towards greater safety The EN 15027 standard requires observance of large safety distances when wire sawing is carried out without implementation of additional protective measures.

flying debris and the risk of injury in the event of wire whiplash.

This, however, is a time-consuming and thus costly procedure and therefore presents yet another important cost-efficiency factor.

Protection installed in no time Fortunately, there’s an answer to this problem. The solution developed by Hilti in the form of the DSW-WG wire guard system makes it possible to easily and effectively contain exposed lengths of wire between the saw unit and the object to be cut. These wire guards can be fitted and removed by a single person very quickly and easily. The wire saw can be set up as usual and the guards, which allow extension up to a length of 3,5 m, are then fitted and attached to the pulley stands. In the event of wire breakage, the wire is contained within the tubular guard, effectively preventing whiplash.

The tubular guard also catches debris before it can fly off.

The Hilti DSW-WG wire guard thus not only greatly reduces the time and effort required to comply with safety regulations, it also provides a higher level of safety for all persons in the working area. The wire guard system provides yet another benefit: Water spray is also contained, so the workplace stays cleaner and less time is subsequently spent cleaning up.

www.hilti.com

In many situations, regulations applicable to the use of diamond wire saws on construction sites demand comprehensive safety precautions. Hilti has now developed a simple solution to this in the form of the DSW-WG, a wire guard system that can be fitted in seconds yet provides far greater safety for operators in the event of wire breakage.

Sawing with diamond wires is the most cost-efficient nonvibrational method of demolishing and removing parts of solid concrete and masonry structures and is thus a popular technique.

In order to ensure high working efficiency during the sawing operation, it’s important that the probability of wire breakage is kept to an absolute minimum.

Less wire breakage This challenge is met admirably by Hilti diamond wire saws thanks to their matched system components and features such as pneumatic wire advance, high-grade diamond wires and flexible wire connectors. The Hilti DS WS15 wire saw, for example, in addition to automatic wire tension, is also equipped with a pneumatic wire tension damping system that ensures constant, finely adjustable tension during the sawing operation and thus helps prevent wire derailment. Although sudden fluctuations in wire tension can’t be avoided, this wire tension damping system ensures immediate compensation of changes in tension, greatly reduces stresses on the diamond wire and therefore extends its life considerably.

Wire sawing without wire guards means keeping all people out of a wide-ranging danger zone.

The second efficiency factor Although these features significantly reduce the probability of wire breakage, the risk can’t be entirely ruled out even with the most technically advanced wire saw system. Accordingly, the EN 15027 safety standard for wall and wire saws specifies a safety distance intended to protect persons from flying debris and wire whiplash in case of wire breakage. The conditions on jobsites, nevertheless, often make it impossible to position the control unit for a wire saw outside the wide-ranging danger area. In accordance with the safety regulations, where persons cannot avoid entering the danger zone, walls or curtains must be erected to provide protection from Easy to fit: Hilti DSW-WG wire guards are attached to the pulley stands.

Less effort, greater safety: Diamond wire sawing with the optional DSW-WG wire guard system.

Never a Bridge Too Far The renovation of an eight km stretch of motorway linking England and Scotland has required an innovative approach to bridge demolition, as PDi’s Mark Anthony reports.

The M6 is the longest motorway in the UK, stretching from a junction with the M1 near Rugby in central England, passing Birmingham on its way to the major cities of Manchester and Liverpool before bisecting Cumbria and skimming the Lake District, and terminating on the A74(M) near the Scottish border. Carrying approximately 44,000 vehicles per day and linking the English and Scottish motorway systems, the A74 has long been recognized as a major bottleneck as it reduces from the three lanes of the M6 to just two lanes.

A £174m investment In July 2006, work was started by the Department of Transport to upgrade the A74 between junction 44 of the M6 to just south of Gretna Green (Guards Mill) where the A74 becomes the M74. In this way there will be a continual motorway connection from London to Glasgow.

The project is costing an estimated £174m and is being funded by the Department of Transport and

overseen by the Highways Agency.

At Metal Bridge a bridge crossing the River Esk alongside the existing A74 bridge has been built to carry the southbound carriageway over the river. In addition, a new, larger and better equipped site for the Vehicle and Operator Services Agency (VOSA) has been constructed a mile (1.6km) north of its current location. At Mossband, a new bridge has been built over the West Coast Main Line railway to carry both carriageways of the new motorway and the all-purpose route.

Preparatory Works Leading UK contractor Carillion Construction and Service Company Ltd (Carillion Roads) is the main contractor and they in turn have entrusted some of the more complex works to Cheshire-based specialist contractor S. Evans & Sons Ltd. Acting as main demolition contractor, S. Evans & Sons were charged with the demolition and removal of the spans from the original viaduct that took the A74 over the main West Coast Main Line to Glasgow. The main problem was the unknown condition of the post tensioning equipment cast into the bridge deck. For a number of years the condition of the tensioning system was remotely monitored from Canada. This factor was the first of the many challenges faced by S. Evans & Sons Ltd. Due to lifting techniques the existing bridge spans had to be post tensioned to maintain the structural integrity of the deck sections during removal. This involved drilling into the concrete deck and installing high tensile anchorages above the bearing location.

Concrete beams were then cast onto the existing deck and 48 mm diameter prestressing bar was longitudinally installed across the deck and post tensioned to support the span cantilever. It took two months of drilling to attach the tensioning anchorages to the deck of each span, and each span took 12 days to prepare for lifting.

The deck sections were removed using the SPMT’s. This process involved the SPMT’s mobilising into their designated lifting location. They would then install the designated lifting capacity and jack the bridge vertically away from the piers. The SPMT’s would then travel with the raised bridge span and off load it onto the previously constructed trestle arrangement.

However, before this could take place, the substandard bearing of the ground was a challenge that had to be dealt with before the demolition process could begin. The entire area was stabilised to increase the ground capacity. This enabled the demolition platform to support the weight of the machinery and lifting equipment.

A 600mm deep layer of 6F2 hardcore material was topped by 400mm of reinforced concrete to provide an area strong enough to

work on. All of this material, together with a considerable amount of concrete will be removed and recycled when the bridge spans have been jacked down.

Breaking and Lifting S. Evans & Sons Ltd elected to break out three of the 950t spans insitu and to lift out a further thirteen. The breaking was handled by Hitachi 470/460 hydraulic excavators equipped with 5t breakers and pulveriser attachments. These were supported by a wheeled excavator with a materials handling grab/magnet to remove the steel and load their bulk tipping trucks. S. Evans & Sons Ltd reported that each span contained between 30 and 50t of 50 mm diameter high tensile steel, which is processed and transported off-site for recycling.

When each of the 13 spans were ready to be lifted off the piers, specialist lifting company ALE used a 1,000t payload set of multi-wheeled bogies (known as SPMTs) to lift each span, and relocate it to the designated lay down area where it was placed on trestle arrangements. The spans were then jacked down to ground level to be demolished. “The site gave us some very interesting problems. The ground was particularly unstable, which meant a lot of reinforcing had to be done prior to the project starting,” says director Neil Evans.

The first stage of the demolition involved removing three insitu spans by excavators and moving the first six spans using the SPMT’s. The spans that were removed during the prepossession works were jacked down and demolished to ensure that the demolition platform space could be reutilised for the Christmas Rail Possession. “We were working around a live railway line that had to remain safe and operational, no matter what,” says Neil Evans.

The final stage of the project was completed during the recent Christmas holiday with the last remaining spans being lifted out during an 84-hour possession on the railway line. Over

600 hardwood mats, 200 packing sheets and 170t of steel road plates were sent to site ready for the possession. The entire track was stoned and matted/plated to protect it, while overhead power lines were also removed, placed into ducts and replaced once the work was complete. “But thanks to the extensive planning we put into this project, and our excellent communications with the Highways Agency, Network Rail and Carillion, the project is bang on target,” concludes Mr. Evans.

When everything is finished and landscaped, this will be a real benefit for people travelling between England and Scotland.

New Rubble Yet, despite a heavy recession, our manufacturers of mobile recycling crushers are not resting. A series of new equipment has seen daylight recently.

During the last year there has been some changes in the recycling industry. In general the common practise to recycle demolition debris instead of dumping it continues to strengthen its position. But the reports come mostly from areas of the world that has a long tradition in recycling. Seldom stories about construction waste recycling come from Asia, Africa and South America. That is why PDi, as an international magazine, is calling out to its readers for more stories in terms of recycling from

equipment for recycling of demolition debris and also other types of waste material. And behind the information stands most of the time a dedicated manufacturer or distributor.

The Sandvik Mobile Screens & Crusher Range Those manufacturers that are profiling themselves strongest in equipment for construction waste recycling are rather easy to mark out. In the recent year’s Sandvik through Extec and Fintec has provided a massive and united attack on the industry offering a wide and comprehensive range of crushing, recycling and screening equipment to among others the demolition and recycling industry. Sandvik has carried out an impressive act when acquiring and incorporating Extec and Fintec in the organisation and the only thing we can do is to lift off the hat for them. In a few years has these three players formed as one providing today the world’s largest a very comprehensive and dynamic line-up of mobile crushing, recycling and screening equipment in the world.

The unification of the Extec and Fintec brands into the Sandvik group of companies has created the The Sandvik Mobile Screens and Crushers range. All together they now deliver all the familiar characteristics of productivity, versatility and low running costs combined with levels of durability and after sales support.

Sandvik first in Secondary Aggregates

But from Europe, Australia and New Zealand and North America we regularly receive editorial material and information about new contractors that has invested in

PDi • Issue 2 - 2009 • May-June

The processing of construction and demolition waste and the production of secondary aggregates places specific demands upon crushing and screening equipment. So when Sandvik Mobile Crushing and Screening (formerly Extec and Fintec) set about upgrading its C-10 and C-12 track mounted mobile crushers to the QJ240 (Extec C10+) and QJ340 (Extec C-12+) specifications, manoeuvrability, productivity and reliability were top of the design agenda.

Few applications are as tough and demanding as recycling and the production of secondary aggregates.

The feed material can contain everything from steel reinforcing bar, with its ability to shred conveyors, to timber that can quickly block a crusher’s jaw. In addition, machines working in this application often do so in an inner city environment and need to be compact and manoeuvrable.

When engineers set about upgrading the C-10 and C-12 crushers, they accounted for these specific demands.

Both new machines are carried on a superstructure that is significantly heavier than their predecessors. The jaws on both machines are quickly and easily operated in reverse to free any blockages and include a fast track system to help free tangled steel reinforcing bar. They also come

with a dual operating system that helps overcome concerns of exposure to Whole Body Vibration.

In standard configuration, the machines are operated from a control panel within reach of an operator standing next to the unit. A separate umbilical control offers some limited stop/start and travel controls and is better for manoeuvring the machine across site. There is a further remote control option that allows the unit to be stopped and started by the machine operator responsible for feeding it.

Both machines have been designed for ease of maintenance and use SKF sealed-for-life bearings as standard together with an automatic jaw lubrication system. Below the jaw discharge point there is a large gap to prevent material blocking between jaw and conveyor. The machine can also raise itself vertically on four hydraulically actuated support legs allowing tracks to be

maintained, removed and replaced.

The new units are building upon the C-10 and C-12 legacy. One company in the UK harnessing the QJ240 capabilities is Sustainable Aggregates and producing structural material for reinstatement. Operating from a 1.2 hectare recycling facility at Copthorne in Sussex, close to Gatwick Airport, the company is using a QJ240 together with a QE340 (E-7 Screen) to produce a high-strength reinstatement material. Fed by a Komatsu 210LC hydraulic excavator, the QJ240 copes with the 10 - 14 daily loads of utility waste, reducing it to the required 50 - 60 mm grade. The unit’s grizzly bars remove the majority of the fines while oversized material is removed through a side conveyor for re-crushing.

“The two Sandvik machines make light work of the material to be processed. They have more than proved their productivity,” says Sustainable Aggregates managing director Clive Holloway. “At present, we are processing about 1,000 t of SMR each week but we hope to produce 4,000 t/week in the near future. And the Sandvik machines are more than capable of achieving those levels of throughput” Holloway believes that productive, reliable and mobile machines are the key to a successful, national network

e Recycling of local SMR production facilities. “The idea behind these small local sites is to process locally, providing a product customised for individual clients, but without the vehicle movements required to move the product from large national depots. We already have top quality BSEN specifications and have applied for our CE mark.

In my opinion, SMR products are the best way to reclaim and recover 100% of construction and demolition waste.

This is compared with the 40 to 60% achieved by conventional methods,” says Clive Holloway. “The savings are enormous for the customer and they are an obvious way of avoiding landfill taxes and reducing their carbon footprint. Once the sites are running to speed they should produce a product that is cost neutral and the productivity of the two Sandvik machines will help achieve that.”

Another company utilising Sandvik technology to convert a waste stream into a revenue stream is West Yorkshire-based Dennis Gillson & Sons Limited. The company is using a QJ340 mobile jaw crusher and a QH340 (X38SBS) mobile cone to create a high quality aggregate from the waste from the decorative stone production process.

The 70 year old company operates at the Naylor Hill Quarry to produce decorative sandstone for flagstones and architectural finishing features, such as lintels, sawn heads, sills and fireplaces.

The QJ340 is fed by a Cat 365BL hydraulic excavator in mass excavation configuration. The crusher is fitted with grizzlies that remove the fines prior to crushing. With its jaws set to >90 mm, the QJ340 feeds directly into the QH340 cone, which in turn produces a 38 mm primary aggregate product. The output from the track-mounted mobile Sandvik cone is also screened to produce a wide variety of other fractions 10, 6, and 4 mm together with a sand product. The company says that the combination of Sandvik machines will easily produce more than 200 t/hour but is more interested in quality than quantity.

A QJ340 is also helping London-based Gregory Demolition to convert its construction and demolition waste into a valuable commodity. In one recent flurry of activity, the company processed 10,000 t of construction and demolition waste in just three days using the 49 t machine. The material, arising from the demolition of three double tunnels and a 3,000 m2 bridge structure

over the Liverpool Street railway line near London’s Brick Lane, was transported to Gregory’s Barking recycling facility for processing by the new QJ340. Managing director Dean Gregory reports that material is crushed to order and that productivity is not a major issue in this application. “The QJ340 is much faster than our previous machines. In fact, our loading excavators have trouble keeping pace with it,” says Dean Gregory.

“Sandvik crushers are reliable and are ideal for demolition work. They’re rugged, well built and best of all, they are not over complicated. This makes them easy to work with and easy to train our staff to operate them.”

The New Rubble Master RM70 GO! At Intermat 2009, RUBBLE MASTER Compact Recyclers, the inventor of and market leader for compact class mobile recycling, introduced the RUBBLE MASTER GO principle with the RM70 GO! “There are many companies from construction and haulage to earth movers, disposal operations and producers of building materials, ready-mixed concrete and bricks, who haven’t properly considered the cost benefits they could gain from mobile recycling with compact, high-performance machines,” says RUBBLE MASTER GmbH founder and chief executive officer Gerald Hanisch.

The company says that the RM70 GO! is the perfect machine, especially for contractors starting out in the recycling business.

GO! means that the solution is fast, direct and gives immediate benefits. “For us this means that we remove every conceivable obstacle from the path of the user before the button is pressed,” says Gerald Hanisch: “After all, there is more to it than just having good machines. We offer a complete business model with guaranteed success. This is our way of making the first steps in this line of business as easy as possible. At RUBBLE MASTER this business model covers individual advice

in terms of the optimum machine for customer needs, the profitable use of the recycled aggregate and support in obtaining permits and also with financing. Thorough training and regular on-site assistance as part of the RUBBLE MASTER Lifetime Support

programme with service checks ensure that value is retained and that operating costs are kept as low as possible. This is how RUBBLE MASTER accompanies its customers on the road to success from starting out to lasting growth.”

The prime task of the RUBBLE MASTER GO! principle is that every RM70 GO! user can operate the machine properly from the start and earn money from the beginning of ownership. The user interface is simple Issue 2 - 2009 • May - June •

and operators will feel confident handling it from the start. Defined maintenance cycles make it easier for the operator and ensure optimum machine service.

Maintenance is easy, due to the large side and rear servicing doors and all the important components can be accessed from the ground. The RM70 GO! is ready for action immediately on reaching site.

Thanks to the comprehensive RUBBLE MASTER ENVIRO concept, the RM70 GO! is very quiet and has effective dust suppression. Weighing under 20t, the new model in the RUBBLE MASTER Compact Recycler range can be transported quickly and easily.

The machine can be used anywhere and the highperformance impact crusher produces up to 120 t/h of high-quality grain from general rubble, asphalt, concrete and medium-hard natural stone. Any reinforcing steel is separated from materials inside the crusher and removed from the aggregate by the magnetic separator.

The running costs for the RM70 GO! are low and gives newcomers to recycling the chance to open up a new, profitable line of business quickly and reliably with mobile rubble recycling. The RM70 GO! is available from the middle of 2009, after completing an extensive series of tests.

Rockster launches R1100 crusher Rockster has launched the new 32 t impact crusher R1100, which complements its existing crushing and screening equipment and enabled the company to enter a new market segment.

“Our existing series of mobile crushers, with the 25t R900 as the biggest machine, has already proved itself and consolidated its position on the international market,” says Rockster chief executive officer Wolfgang Kormann. “However, additionally we got more and more requests from our distribution partners concerning a bigger machine, covering a wider market segment. The target was a compact crusher with a performance of close to 300 t/h, adequate for covering major projects.”

The result is the R1100 that fits into the existing product line and has a fully hydraulic drive system. The R1100 features a 2-step and 1.8 m long pre-screener.

This ensures maximum pre-screening quality, but also a further increase of the throughput rate, a reduction of the wear costs as well as a perfect separation of final material. The main discharge conveyor can be lowered hydraulically, which provides two advantages for customers. “To mount the screen box, an optional feature for the R1100, on the main belt of the machine, the conveyor can be lowered. Therefore, no additional elevating system is required and also the exchange of the different screens can be carried out directly on the ground,” says Kormann. ”Additionally, any material, that may block the crushing process, can be reached and removed easily by just lowering the belt.”

The R1100 also features an impressive performance. During testing the machine was fed with reinforced concrete in lengths up to 1.5 m, for crushing down to a final grain size of 0/63. The result even surprised the Rockster staff as the R1100 achieved an average performance of 260 t/h, with peak production of 345 t/h.

The Rockster duplex system is also an available option together with the screen box RS94, which can be mounted on the main belt of the R1100.

New plant, new products from Hartl Anlagenbau Hartl Anlagenbau GmbH has been in the production of mobile crushing and screening plants for well over 35 years. The units are renowned for their compact and robust construction, innovative technology and excellent production in difficult applications. Whether in recycling or natural stone crushing, the Powercrusher will master all crushing jobs.

The wide range of Hartl Powercrusher products enables the company to offer solutions to all crushing requirements and is based around mobile impact crushers, jaw crushers, cone crushers, vertical shaft crushers, screeners and electrooptical belt scales.

To cater to the global demand for Hartl products, the management of Hartl, brothers Dominik, Alexander and Stefan Hartl, decided to expand the company and build a factory in St. Valentin near the company’s’ existing head office in Mauthausen. On a 60,000 m2 plot of land, the 12,000 m2 special facility was erected and will allow the company to produce up to 400 units per year.

Even the surface treating of the units will be superior as all parts will be powder coated, a huge step in the crushing industry. The introduction of powder coating will be a first in the industry and amount to unparalleled surface quality.

After the powder coating process, the individual components will be assembled at designated islands on a travelling assembly conveyor. One of the major advantages of the facility is the use of just in time production. Each machine will undergo a test run in a specially built test box where operation and quality will be checked. The latest developments from Hartl Anlagenbau GmbH are the PC1 and PC2. Both models are equipped with the latest technology and topquality components and both come with the option of a single-deck HS1 screener, which produces two fractions in one pass.

Powercrusher PC1 Fitted with an impact box with an inlet opening of 1070 x 750 mm, this has the ability of

producing up to 250 t/h. The inside of the crusher beams are lined with wear resistant bolt-in plates. This enables the switch out of individual wear plates possible in a quick and easy fashion. The PC1 has an all-in-one vibration feeder and has variable speed control, which allows for optimal control of feed into the crusher box.

Powercrusher PC2 The jaw crusher PC2 has the Hartl quattro movement, which allows for feed sizes up to 25% larger than conventional down-thrust style crushers. The motion of the swing jaw gives the material a post crush as the rocks leave the crusher chamber. With an inlet opening of 1000 x 700 mm, the PC2 has the ability of producing up to 250 t/h of high quality end product.

The PC2 is equipped with a high volume hopper with sidewalls that can be hydraulically lowered for transport. The pre-screen section consists of an integrated straight grid through which the fines can either be directed to the side belt or directly onto the main belt to be stockpiled with crushed material.

Some covers and housings on both units are constructed out of GFK composites. These materials have been used in the boating and aircraft industries for decades due to their strength, lightweight and corrosion resistant qualities. Hartl has used these covers and materials to create a style that has come to represent the new Powercrusher generation. Another advantage is that they are large and allows for optimum access to the engine compartments.

Both the PC1 and PC2 come with the option of a single deck screenbox, the HS1. This allows for the production of two high quality sellable products in one pass. The HS1 screenbox can be easily mounted with quick release fasteners on the main belt.

A reverse crushing action is capable of relieving blockages.

Extec Screen doubles output

A new 28t Extec E-7 heavy-duty screen is helping to safeguard the future of fine Italian ceramics. Owned by clay excavation specialist Fercav srl based in Modena, the new unit replaces an older Extec machine and has almost doubled output whilst maintaining operating costs. The father and uncle of present owners, Corrado Ferrari and Luigi Portano, founded Fercav srl in 1964. The company is a key supplier of clay to the Marazzi Group, recognised as the world’s largest ceramics producer. Approximately 95% of its annual production is used by the ceramics sector and with demand running high, the company decided to invest in a new heavy-duty scalping and stockpiling machine. The company approached local dealer MAIE spa about a combined rental and demonstration of a suitable machine prior to purchase. With the assistance of MAIE, Fercav decided that the Extec E-7 best suited their higher production needs.

According to Corrado Ferrari, the test was so successful that he immediately stopped renting the machine and decided to buy one. The company says that the most impressive aspect of the Extec E-7 is that it has effectively halved the cost per tonne of production. “The Robotrac was an excellent machine and easily averaged a production level of over 300 tonnes/hour,” says Ferrari.

“The new Extec E-7 costs almost exactly the same to operate but it has almost doubled our production levels. The machine’s exceptional manoeuvrability ensures that the loading shovel used to feed it never has to travel more than 10m, thereby minimising owning and operating costs still further.”

Waste recovery specialist invest in new recycling plant The UK family run waste recovery specialists, F D Todd & Sons Limited, has replaced its elderly recycling and sorting plant with a new system from Blue Group. The new plant can handle the increased and varied volumes currently being processed and ensures projected additional recycling requirements can be easily accommodated in the future. The new installation also has the capacity to batch-run waste using separate individual components of the plant as required.

One of the largest independent F. D. Todd has been a long-standing customer of Blue for many years and added two Powerscreen Powershredder 1800 mobile shredders, one of which forms an integral shredding and volume reduction part of the new plant. The company operates three waste recovery plants in North Yorkshire at York, Thirsk and Knapton near Malton, where the company also operates a non-hazardous landfill. F D Todd is one of the largest independent waste treatment specialists in Yorkshire, running a large fleet of skip and trade waste trucks, roll-on-off vehicles, compactors, crushing, screening, shredding, washing and recycling plants.

The company processes and recycles about 100,000 t of industrial, municipal, commercial and demolition waste every year, including the recovery of paper, card, plastic glass, timber, compostable waste and dirty plastics through an in house washing system.

“Processing and recycling waste is our core business,” says F D Todd managing director Richard Todd. “We specialise in front-end recycling through to final disposal, extracting and reclaiming the maximum weight and value from co-mingled wastes. From the two main separate waste streams that we handle, construction and commercial, we draw off the recyclable fractions and thereafter shred the residual wastes for weigh and volume reduction. Our new recycling plant has been chosen after detailed consultation with the engineers at Blue and we feel represents good value from tried and tested systems. We visited a number of reference sites and were impressed with what we saw

and, significantly, found that our colleagues from Blue fully understood our processing requirements, showing a real expertise in providing a solution to fulfil our needs from inception to commissioning”

Wide array of recycling features The new recycling plant is comprised of a number of compatible processing and materials handling modules. A series of free-standing feed, transfer and discharge conveyors provide the essential linked materials flows for processing equipment, the picking station and stockpiling of varied waste sizes and volumes, including fines. Features such as full skirting, impact bars, feed boots with full impact sections and overband magnets for tramp metal removal are included where necessary throughout the conveyors array.

The primary screener in the recycling system is a Kiverco 1040 Trommel. A heavy-duty model, the fully enclosed rotating screening drum is 13 m long and 3.3 m in diameter, fitted with 50% 40mm

punch plate and 50% 180mm punch plate. The drum speed is infinitely variable with a heavy-duty four-wheel electric drive.

The Kiverco Picking Station is fully enclosed with heating and lighting for operatives’ comfort and security. Six bays and twelve drop chutes are positioned either side of the 1.5m wide and 3.3m long infinitely variable speed conveyors. An overband magnet is included for further safe removal of ferrous metals.

The Nihot SDS single drum separator and Windshifter WS-S provide an additional facility for secondary and tertiary separation. The Nihot SDS uses controlled air to separate waste input into heavy and light fractions, passing on the lighter materials to the Windshifter for further separation. The SDS separator can process varied waste streams, including those with high moisture content and large fraction sizes such as plastics or foils. The Windshifter WS-S also uses a controlled air principle for greater separation of the light fractions and this is also equipped with dust filtration.

Thanks for the demonstration…we’ll have it!

In the UK Robin Concrete & Recycling Limited, founded by Robin Thornham and based in Hull, East Yorkshire, operates from Foster Street Recycling Centre in Hull, where the company concentrates on recycling and also operates a ready-mixed concrete plant served by their fleet of truckmixers. Over the past couple of years, the waste volumes for the recycling business have grown considerably and, needing to increase the processing throughput, the company turned to Blue Group for a solution to their problems. “We’ve worked with the Blue team for

32

PDi • Issue 2 - 2009 • May-June

many years” says Robin Thornham. “They suggested that a Doppstadt AK-430K tracked shredder would be the answer to our predicament, offering the machine for demonstration. This was such a success that I told Blue to leave it where it was as it’s now sold.”

Robin Concrete & Recycling has a 10 acre site at Foster Street, where they process mainly green and building timber waste, in addition to some waste from the surrounding areas. The group is also involved in a landfill restoration project re-screening, washing and replacing non-

recyclables as well as extracting and processing secondary aggregates, which are predominantly used for non-structural concrete production in their own ready-mix plant. The shredded and composted green and timber waste from the Foster Street Recycling Centre is playing an important role at the defunct 20 acres landfill site, where it is used for soil improvement in the restoration process. The company was the first in the UK to purchase a Backhus LT in-vessel composting turning machine and this blends the shredded wood and green materials with liquid waste to produce the compost. Robin Concrete & Recycling also has plans to further develop their recycling and composting activities, with a view to obtaining the necessary quality standards and accreditation for production of saleable compost materials.

The Doppstadt AK-430K Mobile Shredder is designed and built specifically for green and wood waste processing, with large volume capacities for the effective and efficient chipping and shredding of tree-trunks, roots, pallets and building timber waste, green and organic waste.

“We’re very satisfied with our new Doppstadt shredder” says Robin Thornham. “Having worked with the Blue team for some 15 years, we have built a very comfortable working relationship which continues to be an amicable and beneficial partnership, both during the purchasing process and in their after-sales product support”.

Pinden’s new recycling plant In the UK Blue London, part of the Blue Group, has supplied a Kiverco recycling plant to the Pinden Quarry in Longfield, near Dartford, Kent and will be used for the reclamation of clean secondary aggregates from waste. The heart of the plant is a Kiverco static KL 835 Trommel, which features a 2,4 m diameter screening drum set at an angle of 6º with an infinitely variable rotation speed of up to 15rpm. The drum side chutes are fixed with discharge directly under the drum and hinged side chutes allow drum removal through the side of the trommel.

KCM takes Doppstadt shredder for green waste processing In the UK increasing volumes and varieties of recyclable materials coming into KCM Metals & Skip Hire’s recycling plant in Rotherham has seen a significant growth in green waste, which has necessitated an addition to the company’s range of processing machinery. Turning to Blue Group to provide a solution, KCM has purchased a new Doppstadt DW-3060 Shredder from Blue Central specifically to render the green and wood waste for biomass production. KCM’s new Doppstadt shredder is capable of handling tramp material such as metal, which is a significant benefit when processing mixed materials sourced from building and demolition sites. Weighing 23.5t the DW-3060 three-axle, slow-speed, high torque shredder is one of the larger machines in the Doppstadt DW range. Capable of handling larger bulk timber, mixed construction waste and industrial refuse, the DW-3060 has numerous features.

These include optimum tooth arrangement on the roller, reversible fan wheel, modified hopper shape for easy loading, electrically controlled roller reversing and a large return conveyor.

One of the world’s major manufacturers of magnets is Master Magnets who this year celebrates 30 years in business.

The UK based company Master Magnets Ltd has been trading worldwide for 30 years. Over the years they have solved thousands of magnetic separation problems for an extensive range of industries, which has given the company a vast knowledge in industrial applications. Master Magnets are well established as a world leader in magnetic separation and material handling equipment. This is due to the strategic acquisitions, growth and 200 years of accumulated knowledge.

The Master Magnets premises in Worcestershire, UK.

Started in a back office Master Magnets Ltd was founded by Geoff Worley who had 15 years experience in the magnetics industry, and had specialised in magnetic separation and its derivatives. Joining Geoff, as sales director was Cliff Walker, experienced in magnet sales for over 30 years and with worldwide contacts.

Both believed they could use their extensive knowledge and expertise to create and grow Master Magnets.

Master Magnets started business in a back office and sub contracted their production work out to external manufacturers. Cliff Walker led the sales, and appointed agents from around the world, some of which still represent Master Magnets. Geoff Worley managed the engineering side of the business handling the technical and production departments.

As the company progressed through the 1980’s the sales volume grew and so did the company. Eventually Master Magnets set up their own manufacturing facility, which enabled the company to control quality and production lead times more efficiently. Consequently there was an increase in employees, which enabled Master Magnets to expand their product range, services and capabilities.

The 1990’s saw the company installing new heavy duty winding facilities for producing larger and heavier coils for the electro magnetic range of products and a new super strength magnetiser weighing 14t. A test laboratory was also set up to test clients’ samples, enabling the company to specify the correct type of separator for any given application.

The late 1990’s also saw the retirement of Cliff Walker having completed 40 years in the magnet trade. Master Magnets continued to be a family run business and appointed new agents throughout the world.

Major changes Master Magnets undertook some major developments and changes as they entered the 21st century. Their product range continued to expand and their in house facilities were developed. In 2003 Master Magnets acquired Integrated Recycling Systems Ltd, to complement their existing product

range. When Master Magnets acquired IRS they also purchased their factory and offices and the move to Redditch provided the company with increased factory space.

In 2005 Master Magnets also acquired Metal Detection Ltd, and enabled the company to serve a wider range of industries. Master Magnets is now the UK’s leading manufacturer and supplier of magnetic separation, size reduction and detection technology. The company can now offer a wider range of products to benefit an extensive range of industries, including shredders, screens, metal detectors, can flatteners, conveyors and complete turn key plants complementing our existing range of magnetic and non ferrous separation equipment. The company is planning to further expand its product range.

Another sid The major rental

company Cramo from

Scandinavia has more to offer than just construction machinery.

PDi’s Andrei Bushmarin reports.

One of the wonderful things about life is its inexhaustible capacity to surprise. Is it not exciting to discover new facets in things we believed we knew like the back of our hand? As luck has it, the construction business is no stranger to surprises. Just recently, PDi learnt that there is much more to the profile of the Finland-based rental group Cramo than previously known, with one of its activities undeservingly being out of spotlight for quite a while.

“Rental Company of the Year” What did we actually know about Cramo? We knew that Cramo was a major provider of rental solutions for the construction industry, with supremacy in Europe only challenged by two or three rivals. Many might have heard that in 2008 Cramo was chosen to be “the Rental Company of the Year” by the European Rental Association and International Rental News magazine for achieving outstanding economic performances in the last few years. Not so many are aware of the fact that the current Cramo appeared as a result of a merger between the Finnish rental firm Rakentajain Konevuokraamo Oyj and the Swedish Cramo in 2006. Still less known is that it was the smaller RK that bought its larger counterpart, but the decision was taken to stick with the long-recognized brand Cramo. The synergy generated by the merger boosted the group’s efficiency and allowed the new Cramo to consolidate its leadership in the European rental sector. The group has now established a strong foothold in all Scandinavian and Baltic states. With over 280 depots and some 185,000 rental items at its disposal, Cramo also serves the needs of construction-related enterprises in a number of the East European countries including Poland, the Czech Republic, Slovakia and Russia.

However, the success that Cramo has been enjoying in rental business had a side effect of overshadowing one important endeavour in which the company has been involved for decades. The big news is that the group has a very experienced department, which has been tackling concrete sawing, drilling and polishing jobs for 34 years. When PDi met Kari Kataja,

PDi • Issue 2 - 2009 • May-June

a Cramo product line manager and the man in charge of all concrete cutting operations, he told us about the department’s completed and ongoing projects.

34 years in the business In pre-merger times, it was Kari’s father, Hannu Kataja, who ran concrete sawing jobs for RK, which was among a few companies that got the concrete cutting business going in Finland. RK set up a small unit of three men and sent them to Switzerland for training. At first, the unit’s inventory was limited to a couple of hydraulic drill rigs and wall saws. A career spanning over three decades has seen Hannu Kataja go all the way up from an operator to head of the department, which has grown into a 60-strong outfit. When he retired in 2008, his son Kari took over. A diploma engineer, with his graduate study in concrete sawing techniques and a 22-year track record in the business, Kari Kataja drilled his first hole in concrete at the gentle age of eight and was destined to fill his father’s shoes sometime.

Although officially retired, Hannu Kataja still takes an avid interest in the department’s projects.

Snapshot of current operations With all Cramo’s inventory capacity at their disposal, Kari’s men have no shortage of diamond cutting equipment to choose from. The fleet contains hydraulic and electric-driven sawing and drilling systems, supplied by Hydrostress, Braun, Hilti and Husqvarna, as well as Brokk demolition robots. As far as diamond tools are concerned, Tyrolit wires and Husqvarna drill bits seem to be among the most favoured by Cramo cutters. For its 30-plus-year history, the Vantaa-based department branched out into 10 depots dispersed across Finland. Still, contracts carried out in a part of the country known as Greater Helsinki Area account for nearly 50% of the department’s revenue. Nonetheless, Kari Kataja feels that they have gathered enough experience now to move on beyond the confines of the capital. “It is about time for specifiers throughout the whole of A Cramo operator at work on the Helsinki site.

de of Cramo Scandinavia to learn about our expertise and capabilities,” says Kari. “Our services are accredited with ISO 9001 and RALA Certificate of Competence, so all specifiers are guaranteed to get the highest quality of work execution.”

Cramo undertakes to perform any kind of cutting and drilling jobs, but it is wire-sawing projects that Kari Kataja and his operators take a special pride in. One of the highlights includes plunge wire sawing at a Turun Sanomat’s printing house, where the Cramo team cut a 5m wide, 8.5m long and 2.2m deep opening in the concrete floor for installing new colour-printing machines. Lifting capacity limitations and a no-dust requirement imposed by the specifier compelled Cramo to cut the concrete into numerous blocks weighing under 4t.

Another project was completed in the harbour of Hanko, where the department operators assisted in widening a dock ramp so that it could accommodate large modern ships by wire sawing the existing structure.

Wire sawing helps rehabilitate the hospital One of Cramo’s most challenging wire sawing jobs is presently underway in Helsinki, in the city district of Meilahti. The specifier, Hospital District of Helsinki and Uusimaa, is building new facilities for surgical operations and an intensive care unit at the district children’s hospital. Louhintahiekka Oy, which is responsible for earth excavation, explosion and foundation work on this project, approached Cramo to cut a new service tunnel that would go under the existing hospital building. The material to be cut was solid granite. Neither explosion nor impact methods were applicable because of proximity to the hospital. Louhintahiekka Oy had collaborated with Cramo in the past and knew it was a reliable contractor.

After evaluation of all cutting options the contractor decided that wire sawing, the least disruptive and noise-free technique, would be the best solution. Holes for passing the wire through the granite sections had to be made by diamond drilling and the only feasible choice, given the confined working area. For that purpose, two hydraulic drills, a Weka DK-32 and Hilti DD-750 HY, were sent to the site. The working plan was after Cramo were done with cutting Louhintahiekka Oy would crush the rock with hydraulic bursters. A crew of two operators was sent to the site to perform the job in a step-by-step manner.

The first stage involved wire sawing of 42m2 of granite and coring of two 150mm holes to a depth of 2.5m. Braun SSP-15 hydraulic wire saws with electronic feeding system were picked for the job. Cramo decided to make two cuts of 21m2 each. Due to Louhintahiekka Oy’s requirement to complete the first cut in

With much planning and preparation involved, it took operators 9 days to accomplish the task. An underperformance of Tyrolit’s GS48 diamond wire also affected their progress in the beginning. Ever cooperative, Tyrolit promptly supplied another specification, GS45 designed for fast cutting of granite, which proved to be perfect for the job.

With the right tool in place and wire sawing operation streamlined, the Cramo team proceeded to work at a much faster pace. It took operators just 3 days to complete the second cut.

Husqvarna deals with dust Husqvarna’s new DEX dust handling system and the WT 10 electrical water tank minimize the amount of dust and make wet cutting independent of a local water supply.

The dust extinguisher system contains a wet-cutting kit with an integrated regulator that controls the amount of water for binding the dust without creating an excess of water. As the water spray is concentrated on the blade, far fewer dust particles are created than with other spray systems. The result is cleaner cutting with less water and slurry compared with conventional wet-cutting systems.

“DEX minimizes the amount of dust with a minimum of water. It is good both from the user’s standpoint and with respect to the environment. The system halves water consumption for wet cutting and is standard on all petrol power cutters from Husqvarna,” says Husqvarna Construction Products power cutters product manager Håkan Aldén.

DEX also includes a new batterypowered water tank, the WT 10, so that users do not need to pump water

manually and is completely independent of a local water supply. The tank is small and compact and its 3m water hose is coiled around the storage compartment on the base plate for easy transport. The WT 10 holds 10 litres, which gives about 30 minutes wet-cutting. The pump is powered by a rechargeable battery that gives an operating time of about two hours when fully charged. The WT 10 is an efficient accessory to Husqvarna power cutters and drill motors.

“The water tank gives freedom to

the market. So we have now come up with a solution to this water problem. The WT 10 launched in spring has a patent application pending.”

News from Eagle Solutions

Atlas Copco’s hydraulic cut-off saws

US floor grinding equipment manufacturer Eagle Solutions recently launched a new website to promote their long lasting diamond tooling for concrete polishing and grinding. It is designed to give contractors real discounts and rebates toward future purchases. It is a sort of reward programme that means real money to concrete polishing contractors whether they are already a customer or not. Their new website www.

EagleDiamondClub.com explains the details and allows for easy sign-up. Some of the rewards include: eagle gift pack, estimating worksheet that closely figures expenses for concrete polishing, year end rebates based on the volume of purchases, free aluminum Frankfort style adaptor plates, for diamond attachment to Eagle grinders, discounts on equipment, entry in contests for equipment give-a-ways, etc. Eagle Solutions launched this new rewards programme because they wanted to encourage all grinding and polishing contractors to try their diamond tooling.

Eagle product designers and engineers have spent years working to create diamond tooling that would out perform any other pad on the market. They have succeeded in producing diamond pads that can last up to 3,700 m2 (40,000 sq ft) each depending on the machine used, operator experience and individual slab. Eagle Solutions has been a key manufacturer of propane powered floor maintenance equipment since 1989. They long have had a reputation for well-built industrial equipment and customer loyalty.

Atlas Copco’s LS 14 and LS 16 hydraulic cut-off saws are designed for cutting through concrete, asphalt, cement, brick and steel. The 610mm blade on the LS 14 provides a cutting depth of 134mm, while the 1.22m LS 16 offers a cutting depth of 160mm. Both units feature a power-on-demand system that automatically decreases engine speed when a tool is disengaged, reducing fuel consumption and extending the life of the power pack.

Their hydraulic power packs, equipped with wheels and handles, are small enough to transport by pickup truck and can be positioned up to 23m away. Standard features include a hose to deliver water to a diamond blade for wet cutting and a 2m hydraulic twin-whip hose with flat face and quickrelease couplings for easy connection to the power pack hose or an extension hose.

Traxx keeps speeding up!

In a previous issue of PDi the new company Traxx Construction Products was introduced. Traxx is headed by Lloyd Williams, who is a well-known name in the concrete cutting and demolition industry in the entire Asia Pacific region. The rest of the Traxx staff have also been working with these industries for many years.

months Traxx has built up a strong trademark with a wide product range. The design of the products, documentation, website etc plays also an important part in positioning Traxx and has is a major detail in the fast implementation of the trademark.

Market expansion

Traxx Construction Products is essentially a group of individuals and a fully franchised operation where customers deal with the owner of the business.

“Our business is the supply of quality, innovative and competitively priced diamond tools and associated machinery. In essence, machinery that typically consumes diamond tools,” says Lloyd Williams. “We have however, also formed a division that supplies complimentary tools to the respective industries we deal with as well as Consultancy Services to, in particular, the Concrete Sawing and Drilling Professionals.”

Traxx is very young but the people behind it are very experienced. Collectively, today’s TRAXX team has more than 200 years of experience in their respective fields.

And Traxx is doing very well, according to Lloyd, and is quickly building up a strong position not only in Australia, where the company’s headoffice is located, but also in the entire Asia Pacific region. According to Lloyd Australia and New Zealand is priority number one followed by the neighboring countries in the Asia Pacific region. But with a wide and comprehensive product programme Traxx are also open to offer their products on more distant markets. During just a few Ground Penetration radar from Malå.

Shoxx, a specialist in industrial diamond blades, has extended its range of diamond tools designed for professionals in the construction sector. In addition to the original Shoxx X20 blade, the range now includes the Shoxx G13 blade and a series of surfacing cup wheels: the Z U5, the Z A5 and the C E5. The Shoxx G13 blade is designed for cutting hard materials, including granite. It cuts quickly and accurately without spalling. Like all the tools in the range, it uses unique Shoxx technology, which consists of manufacturing segments using extremely strong bonding materials developed in the automotive industry. The Shoxx G13 also guarantees a 20% reduction in vibration, as compared with a standard blade. This technological feat is achieved through the trapezoid shape of the segments and the number of segments used 16 segments compared with 15 in a standard blade. When applied to surfacing cup wheels, the Shoxx technique provides a 30% higher yield, as compared to standard cup wheels. A range of three Shoxx cup wheels has been developed – the Z U5, the Z A5 and the C E5. These cup wheels are made

using segments welded by electro-induction in order to ensure minimum vibration and exceptional stability during sanding. They are, therefore, particularly effective with concrete and other building materials, as well as abrasive cements and epoxy resins. This process also enables users to make considerable savings, thanks to the tools’ exceptionally long life. Two-in-one segments have been developed to provide a surfacing cup wheel that is effective on all types of surfaces. These segments combine cutting edges with layers of polycrystalline diamond. In addition, the research scientists in the Shoxx technology centre have devised tear-shaped evacuation systems that guarantee better ventilation and efficient cooling of the metal. These innovative tools are now added to a range that also includes the original Shoxx X20 blade. Launched in 2007, this diamond tool offers unrivalled performance, which has made the diamond blade the quickest in the market. The Shoxx range will soon include further high-tech diamond tools designed to meet the various needs of professionals.

Some of the key people at Tractive: From left to right Anders Johnsen, Ingrid Johnsen, Johan Hartvik, Marie Peil and Martin Persson.

Not many professional concrete cutting companies have realized the favour that Swede Anders Johnsen and his company Tractive AB have done for the concrete sawing and drilling industry. He and his team have fulfilled one stage of the journey to complete the ultimate concrete cutting system that combines flexibility, efficiency, economy, ergonomics and simplicity.

“We have now completed the circle so to speak,” says Anders Johnsen at Tractive AB. “And we are now well on the way to complete our task. We are now in position to become the leading supplier of professional concrete sawing and drilling equipment. We have travelled a long way and have now developed the complete base for the ultimate concrete cutting system, exactly how we want to have it and how we believe the contractors want to have it.”

chines. Anders Johnsen is very devoted to his job, an attitude often found with owners of private companies. But Anders goes one or two step further in his devotion. Johnsen gave an example of this when he developed the Gearmec concrete cutting system that was sold to Hilti. But this time he has gone far further in his work. It started with the different models of the hydraulic Pentruder saws, which were well-balanced and very powerful machines. The design was unique, and Johnsen used a technique that had not been used before in the concrete cutting industry, but based on transmission techniques that he had made for the motor sport industry in Sweden. This technique can be copied, even though most of the technical solutions are patented. But the drive behind the creation cannot be copied so Tractive should be able to keep ahead of the competition.

“Dedicated is just the first name”

A new thinking

PDi Magazine has followed Anders Johnsen and his company Tractive for many years. About 10% of Tractive production is transmissions for racing and rally cars. The remainder is focused on the development and manufacture of advanced equipment for concrete sawing and drilling. What is unique for Johnsen and his 24 employees is their dedication. And Anders is the most dedicated. On the 15th and 16th of June Tractive gathered around 200 clients and distributors at their new premises in the city of Borlänge in mid Sweden. Design department, manufacturing and administration are located here. The production facilities are like a laboratory and are light and clean with state-of-the-art computer controlled ma-

The Open House days at Tractive in June were like a paradigm shift for the modern concrete core drilling technique. Maybe it sounds a bit exaggerated, but the Pentruder concrete cutting system has changed the way concrete cutters work. Tractive has introduced a new drill stand that is compatible with the Pentruder rail system. With few components, all with low weight and with maximum precision, a concrete cutter can manage all simple and complex concrete cutting tasks with very low risk of break downs and with high capacity that makes the job much more efficient.

Even though the hydraulic machines are still available it is the HF equipment that Tractive is selling. Small and light

digm Shift” electric motors with the HF technique with a new contact system in combination with the Tractive gearbox principles, is the heart in the Pentruder equipment. Five HF wall saws, including the new Pentruder CBK, the fairly new wire sawing unit Pentruder 3P8 and the brand new Pentruder modular concrete cutting system complete the current line. These can also be used with the Pentruder standard rail system. All of the equipment can be integrated with each other and contractors do not need to bring so much equipment to site to carry out most types of work.

Tractive’s latest news is the new Pentruder Core EZ core drilling system, which contains different modules that integrate with the new MCCS system. It is a completely new principle for core drilling with a completely new and universal drill motor with interchangeable gearboxes with different transmissions. With Core EZ Tractive is placing the power in the centre where it is needed. A traditional core drill rig counteracts, as the drill stand needs to be placed on one side of the core bit. The more power the more the whole unit wants to move sidewise. With the new system from Tractive the drill motor and the stand guarantees that the power is fully used where it is needed in the centre. The Core EZ system has been developed together with Warren Duncan at the company US Saws in Santa Ana, California, USA. Tractive has further developed the basic principle mainly for drilling medium to large size holes. Now development has started on producing machines for drilling small diameter holes.

New is also a simple and easily manoeuvred quick coupler, which makes the change of drill bit fast and easy. There is also a chain saw module under development. “We and some very experienced people are also working on a interesting flat saw equipment project. More then that I don’t want to say.

Our goal is though to introduce it at World of Concrete next year,” says Johnsen.

The foundation to something big What Tractive demonstrated in June is the foundation for

something that can be very successful and most of the participants PDi’s editor spoke to agree. The new equipment displayed is still under development and some changes might occur before final release.

“We are now ready to meet the global market. Now we will start focusing much harder on marketing our products and we want to grow in terms of turn over and geographical spread. We have been very tied up with product developments and optimization of our production plant. But now I feel that we have those things behind us and can focus forward with full speed,” says Johnson.

Sugar Sweet DEMOLITION This is heavy duty demolition! An FR200 swivelling hydraulic crusher and three Marilyn CS 100RS shears mounted on Liebherr 974 excavators for the demolition of a sugar refinery just outside of Valladolid.

Sucrose, by which is the majority of the sugar that we normally consume, is the end product of sugar beets. It is processed in precise phases that require the use of conveyor belts to store the product in silos and the use of channels and pumps for transferring the sugar beets from the silos to the factory. At this point, the sugar beets are chopped and “diffused” (a process that allows the transfer of the sugar).

Finally, the “juice” is purified, concentrated, cooked, centrifuged and finally, refined. And why this information? It’s easily explained, this ponderous collection of machinery and agro-alimentary technology is the scenario in which Italian demolition attachment manufacturer Trevi Benne tested four pieces of equipment to see how they would handle the demolition of a colossal sugar refinery.

The job site area

Text & Photo by Cristiano Pinotti

We are in the outskirts of Valladolid, inside what was once the largest sugar refinery in the city. We find ourselves surround by silos and conveyor belts that comprised an area of over 150,000 m2 in which sucrose was extracted for over 40 years.

Abandoned for two years, the Valladolid plant performed all the processes for transforming sugar beets: stocking, cleaning, transport, grinding and chemical treatment through to final refining.

Today, the activity is completely abandoned and Demoliciones Usabiaga - a company founded in 1998 by Gruas

Usabiaga (Ordizia, Spain) and that already has numerous public and private jobs underway - is engaged in the complete demolition of the building. At first, this activity, together with the reclamation of the area, was estimated to take six months, but the presence of a significant amount of asbestos to be isolated and then disposed forced the company to double the completion time. In addition, the demolition is especially difficult due to the presence of many reinforced concrete structures and a significant quantity of iron.

An established partnership As mentioned, the contractor for the work is Demoliciones Usabiaga, a company with over 200 active demolitions including Benfica stadium, an office of Santander Bank, a 180-meter chimney in Burgos and the Windsor building and Air Force Hospital in Madrid. For all these activities, the Spanish company uses a fleet of Liebherr excavators often equipped with various types of Trevi Benne attachments. The list of demolition equipment purchased by Demoliciones Usabiaga is a long one and fully demonstrates the collaborative relationship between the Iberian business and the Vicenza Company.

In fact, over the years, Demoliciones Usabiaga has used two HC series pincers (one HC 25ND and one HC 100), for CS-family shears (three CS 100RS’s and one CS 20RS) and seven FR crushers (two FR 50ND’s, one FR 70ND, two FR 100N’s and (two FR 200’s). In particular, in the job site that we see illustrated in these pages, the Liebherr 974 excavators are equipped with an FR 200 swiveling crusher and three Marilyn CS 100RS shears (the latter weighing 10 tons) involved in the cutting and recovery of the ferrous material, which, as was said, is very abundant on the job site. But now, let’s take a closer look at the machinery used for this demolition.

The FR 200 crusher

Before getting into the characteristics of the FR line and the model FR 200, in particular, it’s worth reflecting on one detail: Trevi Benne’s orientation towards the creation of special machines. This orientation, which seems to be innate in the Venetian company, is based on three fundamental principles: to offer an alternative solution to a specific request, to personalize the product and to translate the client’s individual needs into a unique and effective product. Starting from these assumptions, Trevi Benne was able to specialize in the production of “over-sized” demolition machinery. Among these the model FR 200 stands out. Like all Trevi Benne creations of this tonnage, The model FR 200 is characterized by an operating weight of over 20,500, an opening of almost 2 m, a height of over 4.5 m and two side-by-side pistons capable of generating a point force of 350 tons.

The Marilyn CS 100RS continuous-rotation hydraulic shears are intended for the most modern industrial demolition job sites, which need significant cutting force at considerable heights and for professionals that recycle ferrous materials and scrap.

it arose out of the need to confront a very complex working situation that was concretized in a collaboration with a technical office capable of developing and designing the equipment through a procedure that went from feasibility analysis to a design and three-dimensional study and finally to production. The FR 200 swivelling hydraulic crusher amplifies all the qualities demonstrated by this line, which has proven itself in job sites in half the world. In fact, the structural characteristics of the FR series allow an operator to confront the phases of primary and secondary demolition with a single piece of equipment.

Thanks to continuous rotation, which reduces movements to a minimum and increases precision, the FR’s function as pincers while the crushing function is provided by demolition jaws enhanced with two interchangeable blades arranged for shearing the iron and round bar contained in the concrete. In addition, the presence of a series of hydraulic speed multiplier devices allows the FR series to significantly reduced the closing time of the jaws, increasing daily production. The use of the cylinder in an upside-down position allows the shaft to work completely protected and, unlike the other models of the FR series, the FR 200 does not require the use of interchangeable bolted teeth. In particular, the model FR 200 - with its over 20,500 kg of operating weight - is a real “demolition giant” equipped with an opening of almost 2 m, a height of over 4.5 m and two side-by-side pistons capable of generating a point force of 350 tons. Obviously, a machine of this size can only be used on excavators between 100 and 200 tons.

The Marilyn CS 100RS shears This continuous rotation hydraulic equipment is intended for the most modern industrial demolition job sites, which need significant cutting force at considerable heights and for professionals that recycle ferrous materials and scrap. The evolution that distinguishes all Trevi Benne products led to the definition of a piece of equipment that was increasingly reliable and met the needs of users. To improve the cutting of the material at the tip, the shape of the reversible tip blade was modified and the dimensions of the guide were increased, while the cylinder was mounted upside-down to protect the shaft. Protections were created for the seats of the blade screws to avoid wear. In addition, the geometry of the mouth and the arrangement of

the blades allow a clean, linear cut of the iron. The search for perfection led the Vicenza Company to make further improvements, which involved perfecting the line and structure, the latter to increase resistance to flexion.

The presence of the safety pin locks rotation during rest, avoiding unwanted, dangerous movements during movement and transport. It should also be remembered that each individual model of CS shear could be easily installed on different operating machines in place of the bucket or in place of the arm by removing the penetrator, depending on the operating weight of the excavator. A regulation system eliminates any play between the mobile jaws and the frame of the shear, ensuring the correct position of the jaw (the regulation is performed during the assembly of the shear and guarantees that the blade of the mobile jaw will be perfectly aligned with the blades of the shear body).

In addition, to keep the blades of the mobile jaw and the fixed body always aligned and parallel to avoid “scissoring,” there are two milled spacers that can be beveled to guarantee the optimum working position.

Despite the ongoing global recession, that has effected the global building and construction industry, manufacturers of demolition attachments continue to develop and release new products. Some are featured on the

Three novelties from Indeco New multi tool Italian breaker and demolition attachment manufacturer Indeco has introduced new products. At Intermat the company released a new multi demolition tool named Multi 1000. Multi 1000 is designed to meet the needs of the American market, where large-size equipment is more popular. The Multi 1000 is the ideal tool for large-scale demolition work and can be mounted on carriers from 36 to 60 t. The other features, which have made the products in the Multi series so successful, are all on the Multi 1000, including its innovative design and its exceptional robustness and versatility.

New rotating pulveriser Next novelty from Indeco is the new rotating pulveriser IRP 500. According to Indeco it is small in size but big in performance. It is, according to Indeco, the smallest rotating pulveriser, for excavators with an operating weight of 10 to 20 t.

“It may be small but it packs a great punch,” says Indeco’s Michele Vitulano.

The latest addition to Indeco’s rotating pulveriser range was designed to express the greatest possible breaking power when used on mini- to midi-range carriers, 12-18 t the optimum combination, with 10-20 t also being feasible. The n e w I R P 500’s features enable it to achieve excellent productivity even on less accessible terrain, which requires the use of smaller, more agile machinery.

New Anti BlanK Firing System The next news from Indeco fits also in PDi’s breaker feature but is still a demolition attachment innovation.

Indeco is now

releasing the new Anti Blank Firing systemsystem. It is installed as standard on all of the midi and maxi range Indeco breakers. The system cuts out blank fire by eliminating any down pressure from the breaker whenever the tool is not resting firmly on the surface to be demolished. This increases the service life of all components subject to wear and tear, as well as reducing stress to the breaker body and excavator arm. “Other manufacturers, in an attempt to satisfy the demands of the market, claim to have installed similar systems on their breakers. In many cases, though, they are in fact just the normal systems needed to function the specific gas or oil circuits on their breakers. Here at Indeco, we decided to do things differently. Instead of rushing into announcements, we preferred to spend our energies on designing a true innovation like the ABF system, which actually improves the performance of our products and increases our competitive advantage on the market,” says Michele Vitulano.

New Grapple jaw set from Allied-Gator The US company Allied-Gator, Inc., has added the MT Grapple Jaw Set to the patented MT™ Series Multi-Tool that utilizes a 2-over-3-tine configuration with dual moving jaws and unrestricted 360º rotation. It provides precision sorting ability and takes material handling to a new level by giving users the ability to compact and density material.

The MT Grapple Jaw Set will be available in 11 sizes, which range from the MTR 5 to MTR 180

weighing between 363kg and 23.5t. With the Allied-Gator MT Series Multi-Tool, demolition and recycling contractors will have the versatility to perform all shearing, crushing and material handling needs on site with one tool, utilizing the variety of available MT Jaw Sets.

Another new product from Caterpillar Work Tools B.V. is the P300 line of the multi-functional Concrete Crusher hydro-mechanical work tools for hydraulic excavators with the P315, P325, P335 and P360. “This new line of crushers, brings added value to our customers,” said Caterpillar Work Tools B.V. Commercial Manager David Becktel.

“Caterpillar customers now have access to a range of crushers with higher cost-effectiveness, flexibility, ease of use, and functionality.”

The equipment substantially limits the amount of vibration and noise and is suitable for concrete demolition in residential areas. The hydraulic concrete crusher combines several concrete demolition operations in one piece of equipment.

These include breaking out concrete from fixed structures, pulverizing concrete and cutting reinforcement rods and small steel profiles.

With a mounting bracket this tool can be exchanged among several carriers and in combination with the dedicated CW quick coupler, a swap between other Caterpillar work tools can be done very quickly.

Ease of service has been a design principle from the beginning. The bolt-on teeth and cutting blades are replaceable and the hydraulic system is easy accessible through bolted hatches. A stock of wear parts guarantees that downtime will be kept to a minimum. Caterpillar supports its work tools with a comprehensive range of before and after sales services that cover everything from advice on work tool selection to operator training, equipment management, and a range of financial and insurance products.

Caterpillar’s new G325B Demolition and Sorting grapple Caterpillar Work Tools B.V. has also showed a line of new developments recently. First out is the new multi-functional Demolition and Sorting grapple G325B for use with 28-35t class hydraulic excavators. “The addition of the G325B Demolition and Sorting grapple expands our current work tool range to the demolition market. We believe this addition, coupled with our technical and application expertise, will continue our leadership position as a global excavator and wheel loader attachment supplier,” says Caterpillar Work Tools B.V. commercial manager Dave Becktel. “We look forward to providing our customers with improved value in support of their demolition and sorting tasks.”

The multi-functional grapple can provide considerable savings in transportation and dumping costs as well as manpower, as it is possible to sort out demolition debris at source and transport it separately to recycling plants. It is very much suited to stripping a building or structure before final demolition. With the increase in environmental regulations it is a big asset.

Caterpillar’s new S300 B-series scrap shears

Caterpillar Work Tools B.V. has extended the S365B and S385B range of B-series mobile Scrap and Demolition shears with the S320B, S325B and S340B for hydraulic excavators.

The S320B, S325B and S340B fit Caterpillar excavators in the 10t to in excess of 60t class excavators. The shears can be mounted on either the boom or stick, and cater to all needs for

scrap processing and demolition applications.

“The performance and durability improvements will further build on the already excellent reputation of the S300 B shears,” said Caterpillar Work Tools B.V. commercial manager Dave Becktel.

“With an emphasis on quality, value and safety Caterpillar has improved on our already excellent line of scrap shears.”

The shear and knife design improves cutting performance and the hardened piercing tip of the upper jaw maximizes productivity when piercing is required. All S300 shear models are equipped with 360° hydraulically operated rotators ensuring a quick and precise placement of the jaws in a cutting position without moving the excavator. Cat shears are designed to cut and reduce the size of metal items commonly found in scrap yards and demolition sites. The straight lower jaw works with the apex of the upper jaw, compressing and flattening the steel before the cut. The straight lower jaw maximizes shear force and creates a more efficient cut. The new shape of the housing provides improved protection for shear components and better positions the jaw relative to the stick. The cutting edge design greatly improves the protection of the cylinder that eliminates the use of a cylinder guard by extending the housing to cover the cylinder rod.

New multi processor from Promove Another Italian manufacturer, Promove, has recently also launched a new multi processor tool crusher CP1510 R. Main difference from the previous model is the single-pin frame that is now common to all other CP models. It has the advantage of optimising the action of cylinders’ power, synchronized closing of the two jaws and increased speed in changing the sets of jaws.

In addition the cylinders’ oscillation in the new geometry is limited within a few degrees to keep momentum and closing power as constant as possible through the breaking cycle.

Two new pulverisers from Atlas Copco

New Caterpillar Coupler System Caterpillar Work Tools B.V. has introduced the new Fusion wheel loader quick coupler, which pulls the work tool closer to the wheel loader for machine performance comparable to pin-on versions. The patented design moves the centre of gravity closer to the machine while enabling the loader to pick up and use a wide range of work tools.

“Fusion is designed for Caterpillar wheel loader models ranging from the 938H to the 972H, including the IT38 and IT62. The unique, single interface allows many machines to share the same work tools and a cost reducing system

for multi-loader fleets,” said, Caterpillar Work Tools B.V. commercial manager Dave Becktel. “Fusion also gives the operator excellent sight lines to the work tool, load and target location. The new, open coupler frame design makes it easier than ever before to engage and disengage attachments.

Offset tines and other design attributes of Fusion Pallet Forks work in conjunction with the Fusion Coupler to increase visibility of the tines at ground and truck bed height for confident and efficient handling of palletized loads.

Nimbus & Sa Nimbus is a product line of Norton, the world-leading brand of Saint-Gobain Abrasives - the only company in the world manufacturing all 5 types of abrasive products: Bonded, Coated, Thin Wheels, Super Abrasives and Construction Products.

Norton-Nimbus is a product range dedicated to the professional sawing and drilling contractors as well as industrial manufacturers, whereas Norton-Clipper targets building and general construction through distribution networks.

“A clear focus” More than a product range, Nimbus has its own dedicated team with its own philosophy, where customer satisfaction is paramount, and that defines itself around: • Exceptional product quality through manufacturing excellence

PDi • Issue 2 - 2009 • May-June

• Proximity to the market with fast service and on-site technical support • High performance and complete product offering • Innovation and technical leadership

“More than a relationship with the professional end user, it’s a partnership that we seek. Our strength is the experience and dedication of our professional team, backed up by the breadth and support of an international group,” says a Saint-Gobain spokesman.

2008 a year of growth and innovation for Nimbus 2008 was the fifth consecutive year of double digit sales growth. That comes primarily from developing the commercial network through front line recruitment and aggressive penetration of new markets, especially in industrial applications. The best example is the brick and concrete block grinding industry where Nimbus has reached a strong leadership position because technical leadership, exceptional service and local manufacturing are what customers are looking for.

A significant investment in R&D and technical development, both in terms of product and process, enabling us to better serve the industrial and contractor markets. New manufacturing processes have allowed us to develop higher performing diamond tools in drilling.

Experiences on aerodynamics, vibrations and dust extractions allowed us to introduce new designs to increase the speed, comfort of cut and life of our blades. The new V-Max blade, introduced in 2008, quickly became the reference in Wall sawing, outperforming the competition, and especially in the toughest aggregates.

“How Nimbus can support the contractor through the economic crisis?”

In times of crisis, the last thing a company want to do is reduce the capital investment. Saint-Gobain has invested in some major pieces of equipment at its UK and Luxembourg plants. As an example, Nimbus will now introduce its entire core drilling range with laser welding attach-

aint-Gobain ment. This will have major benefits for the quality and performance of its cores, but also significantly improve the productivity of the plants and the service to customers.

Another new manufacturing process, patented by SaintGobain, enabled the manufacturer to develop a new thin wall crown with double the diamond height compared to the market standard. This innovative product, called TWICs, will hit the market in July.

In times of crisis, cash is the main concern of the contractors. Extensive stock holding has become a thing of the past, suppliers are now expected to provide faster service on a wider range of products. Saint-Gobain Abrasives is one of the last manufacturers to still have three production facilities in Europe and 100% of the diamond tools from the Nimbus range are made in these plants.

This means that Nimbus can supply any diamond tools within 24hours, including a 2 m wall saw blade, which none of the competitor-importers are able to do, according to Saint-Gobain.

IACDS elects new In early June 2009, IACDS held its annual meeting in Ireland’s capital Dublin, a city with a great literary tradition and just as great inebriation culture. 22 delegates from 13 countries flocked to the hometown of Oscar Wilde, George Bernard Shaw, James Joyce, “Guinness”, and “Jameson” to attend a two-day conference at which a number of important decisions were made.

Report by Andrei Bushmarin

The event was sponsored by 7 major suppliers - Diamond Innovations, Anzeve, Husqvarna, Tyrolit, Nestag, Hilti and Cedima whose continued support was, and remains, invaluable to IACDS. The delegates, who got quickly immersed in true Irish hospitality, also reserved a ‘danke schön’ for German-turned-Irish Eva Stolz of destination management company Aspects of Ireland, who assisted the conference in every way possible.

Easing the burden This time around, the number of participants was somewhat lower than the previous year in Valencia. This slight drop in turnout may be ascribed to various reasons, not the last of them the global recession, which grim impact can be felt almost everywhere. On the upside, IACDS heartily welcomed a new member, Bulgarian company Enemona SA, based in the town of Kozloduy, which joined the ranks of what used to be called “non-active” members of the association. As the delegates introduced significant changes to the association by-laws and the system of membership dues, this old terminology became no longer applicable. From 2010 on, the IACDS membership structure will provide for 3 main categories: bigger national associations boasting a membership of over 50, under 50 smaller ones, and individual members. The voting rights are distributed accordingly: the bigger associations have four votes at meetings, the smaller ones two votes, and the individual members one. The set size stipulations cannot prevent, however, a smaller national association from claiming the status of bigger one, provided it is prepared to pay the higher dues. The alterations to the membership and dues structure aim to ease the financial strain on the smaller associations that previously had to contribute the same amount every year as the bigger ones. The other objective was to attract new members and get individual companies more involved in the decision-making process. The meeting thus decided to halve membership fees for the smaller associations, while increasing them for individual members, in exchange for 1 vote, in order to make up for the resulting balance-sheet deficit.

The Spanish national association (AEDT) joining the international association a year ago is one of IACDS’s most recent accomplishments. Now Peter White, a man with 44 years in the business, is poised to steer the association into the future. He will be backed by two vice-presidents, Norikazu Shibuya of JCSDA and Jose Blanco of AEDT.

Diamond dust, GPR and wire sawing The second day of the conference saw the delegates travelling to Diamond Innovations’ manufacturing facilities to see for themselves the production cycle of industrial diamond, and to complete the official proceedings there. The visitors were shown a series of presentations and led through all stages of diamond transformation, from graphite right through to end product. Some cheerfully admitted to an unforgettable sensation of hearing diamonds, albeit artificial, crunch under their feet as they went through the plant.

The excursion over, the duly impressed delegates thanked Niall Murphy, John Quinn, Pat Lynch and Majella Rickard of Diamond Innovations for this most interesting and informative tour, and Pat O’Brien for actually making it happen.

As a special treat for the delegates, Rick Norland of the USbased Construction Solutions was invited to deliver two technical presentations at the meeting, courtesy of CSDA and Pat O’Brien.

Earlier this year, Rick had given those presentations at a CSDA convention and now came to Dublin to share his extensive knowledge with the IACDS members. The first speech was dedicated to Ground Penetrating Radar, an emerging business with great potential, which, however, at the present stage of development, remains a tricky operation requiring a lot of skill. There are a handful of companies, which now supply the market with GPR, but it takes much more than just a few hours’ training to become an accomplished GPR operator. One of the biggest challenges operators may face involves detecting now non-existing structural elements that once were in the concrete but keep popping up on the radar screen anyway. Rick Norland’s vision is that the GPR business will fork in its evolution into two separate approaches for specifiers

Representative of IACDS’s new member, Bulgarian company “Enemona”, Boyko Tomov. to choose from: regular sawing and drilling companies, which will incorporate GPR into their broad service package, and niche GPR contractors specializing in this particular type of work.

On the second day, Rick educated the delegates on the ins and outs of wire sawing. Those who were present would agree that it was pure joy learning from someone, who was so knowledgeable and so obviously in love with what he did. The presentation called Advanced Wire Sawing Methods elaborated on the nuts and bolts of this most sophisticated concrete cutting technique, in particular on the benefits of dry wire sawing. According to Rick, this method, provided the machinery is set up correctly, is far more advantageous than wet cutting. He also gave a few tips on underwater and straight steel cutting. The presentation was liberally sprinkled with case studies derived from Rick Norland’s lifelong experience, which served to reinforce the impression of his extreme competence.

Weathering the crisis As the delegates went on to report on the current state of the construction and concrete cutting businesses in their countries, the global credit crunch started to rear its ugly head all over the place. Every report, with the exception of Germany, and arguably Switzerland, contained an array of frustrating facts and dismal forecasts. Construction market in Spain is all but dead, with banks rebuffing any attempt at getting a loan for a building-related project.

Wages are paid up to 170 days in arrears, so the workers tend to go looking for a job elsewhere. Austria reported massive lay-offs, with unemployment rate forecast to climb as high as 8-9% in 2009. It is hardly surprising that in their plight people increasingly resort to seeking employment outside the country. In his turn, President-elect Peter White informed the meeting about the “almost catastrophic” situation in the UK, as business went down there as much as 40%.

In Sweden, another important European market, things are only marginally better, with market drop estimated at 30%. In the other corner of the globe, North America performs no better than the Old World. According to the CSDA 2009 market survey, non-residential building is down 42%, residential building is down 50%, with no chance of any recognizable recovery until late 2009. Non-building construction is up though, compared to 2008, thanks to the government’s stimulus program. Germany is

the sole country that sticks out of the sea of gloom, which seems to have engulfed the entire industry, as an island of stability, and prosperity even. Hans-Georg Wagener of the German association portrayed almost an idyllic picture, with state money pouring in and everybody’s happy. The reason for this happiness was provided by the national government, which allocated enough funds for the reconstruction of the country’s infrastructure, thus giving local contractors the opportunity to get through these hard times relatively unaffected.

Setting out new goals

What would a trip to Ireland be without visits to Guinness and the Jameson distillery.

The meeting nearing its close, the delegates rushed through the remaining issues. There was a brief review of the most recent Diamond Award, which drew 19 entries from all over the world (see PDi 5-2008, page 52 and PDi 1-2009, page 48).

The winners were announced earlier this year at the World of Concrete show in Las Vegas. Its popularity on the rise, the contest has now transcended the borders of Europe, where it originated 9 years back. Having considered this, IACDS decided once again to time the next competition with World of Concrete, which is scheduled to take place in Vegas in January 2011.

This year, the matter of the IACDS website re-design was brought up once again. The change is overdue, given that the association’s window to the world, in its current state, simply cries out for an overhaul. With an intuition-defying interface, the site is hard to navigate; its structure is cumbersome and dated, lacking many modern-day features. As much as the idea of giving the

website a facelift appeals to the delegates, this project has failed to materialize so far. Hopefully, it will get underway in 2009, as IACDS figures out costs for the upgrade.

With Bauma coming up in 2010, the participants did not waste their time on choosing a place to convene next time. The 2010 IACDS meeting will be held in Salzburg on Monday, 26 April, the very next day after the show. The delegates intend to complete the proceedings within just one day by taking out speeches and presentations of the agenda. Instead, on 24 April, the association plans to run a half-day seminar at Bauma dedicated to the current trends in the concrete cutting industry. The seminar will be built around GPR and other advanced methods allowing the detection of hidden construction elements. A few GPR manufacturers have already registered their interest in this workshop.

At the very end of the meeting, the delegates were advised of another 2010’s ‘must-visit’ event, a specialist trade fair Demcon, which would focus exclusively on concrete sawing, demolition, recycling, floor preparation, and dust extraction. Demcon will be held in a suburb of Stockholm on 9-10 September 2010.

Although IACDS approved the idea of co-operation with Demcon in years to come, the delegates saw no reason to discard the time-honoured tradition of meeting at Bauma just yet.

NDA and CSDA Form Alliance Patrick O’Brien (left), executive director of the Concrete Sawing & Drilling Association, presents a plaque to Raymond Passeno, CIH, the new president of National Demolition Association, to commemorate the new reciprocal alliance between the two organizations.

The National Demolition Association and the Concrete Sawing & Drilling Association announce a reciprocal association agreement that will promote the exchange of information between the groups to enhance the safety and professionalism of their industries.

“Because our industries often work closely together, we think a reciprocal alliance will benefit both groups,” said National

Demolition Association executive director Michael R. Taylor. “We think it’s natural to encourage a closer working relationship between our associations to foster a spirit of cooperation,” added Concrete Sawing and Drilling Association executive director Patrick O’Brien.

The Concrete Sawing & Drilling Association is an international organization of more

PDi • Issue 2 - 2009 • May-June

than 550 contractor, manufacturer, distributor, and affiliated member companies from the concrete construction and renovation industry. Its mission is to promote sawing and drilling contractors and their methods, as well to provide a forum for members to share their ideas, needs, and concerns in a constructive framework to further enhance concrete sawing and drilling technologies.

The National Demolition Association is the leading global trade organization representing the demolition industry. At present, the association counts among its members more than 1,100 companies in the United States and Canada, as well as many companies from around the world.

Membership includes not only demolition contractors, but also general contractors, civil engineering firms, and recycling, landfill, and salvage operations. The association’s efforts help members stay abreast of en-

vironmental, regulatory and safety matters, keep regulators informed about issues facing the industry, increase public and industry awareness, and provide members with networking opportunities and information on the latest technical advances in equipment and services.

CSDA has been fostering a spirit of cooperation with other associations since 1993 when it was instrumental in creating the International Association of Concrete Drillers and Sawers. IACDS is an umbrella organization of sawing and drilling associations from Australia, Austria, Germany, Italy, Japan, Netherlands, Sweden, Switzerland, United Kingdom and the United States.

Other reciprocal members of CSDA include organizations like ASCC, CSDMA, FICAP, SMI and TRMCA. www.demolitionassociation.com www.csda.org

Kilnbridge went deep in London UK concrete cutting specialist Kilnbridge Construction Services Ltd took on a tough deep drilling job in Picadilly Circus, London recently. The project involved the conversion of the former Regents Palace Hotel, in Piccadilly Circus, London. The new mixed use development, of shops, offices, restaurants and residential buildings will retain 50% of the original facade, all of the basement perimeter walls and elements of the basement and superstructure slabs but will otherwise be completely re-built. To prepare for construction of the foundations needed to support the new structure, extensive mini-piling work had to be undertaken. Kilnbridge Construction Services Ltd took on the job of Coring holes in the basement slab, ready for piling.

Extensive Core Drilling The sheer amount of drilling involved in the job was impressive – over five hundred 400mmØ diameter holes were drilled, averaging 2 metres deep. In some parts of the hotel basement, the holes were reaching an incredible 5 metres deep. Whilst 400mmØ was the most common diameter, Core up to 600mmØ were also used on the perimeter of the building.

Tough Conditions As if drilling 400mmØ 5 metres deep wasn’t a dif-

ficult enough challenge, the concrete involved made conditions even harder. As the pictures of extracted cores show, the concrete was extremely hard, with a Thames London Flint aggregate. This was no small aggregate either – the concrete was mostly filled with large, 40 – 50mmØ Flints, with some chunks over 100mmØ. Not only did the basement slab contain rebar with the usual 40mm steel, Kilnbridge Construction Services Ltd found steel I-Beams at random intervals in the concrete.

Atlas Copco CC 2500 S devours derelict building It took Atlas Copco’s Hanover Service Station only a few days to prepare the CC 2500 S for the demolition task. One week later nearly half of the building had been demolished. The CC 2500 S produces a 300t cutting force (133t at the tip) and was able to tackle this difficult job. The large cutting jaw and the 360º rotary gear allowed the cutter to be positioned with high precision for rapid progress.

Excavator operator Dirk Bartke is enthusiastic.

Because of the exact handling properties and the strong performance he believes that the demolition job covering some 6000t would be complete at the end of the second week and improve the Hanover-Letter parking situation.

Paradise Found!

In the UK the National Federation of Demolition Contractors has moved toa new head office in Hemel Hempstead on the outskirts of London. Mark Anthony reports.

While the great and the good of the National Federation of Demolition Contractors gathered in London for their annual general meeting on 6 March, a team of builders, carpenters and electricians were putting the finishing touches to the Federation’s new home in Hemel Hampstead, Hertfordshire. And while the “Paradise” name given to the commercial estate upon which the NFDC premises now resides can only have been created by someone with a keen sense of irony, the new offices are a sight to behold.

New NFDC president David Darsey, who hosted the official opening by local member of Parliament Mike Penning, said that the new premises gave the Federation the facilities it needs, and which it deserves as the recognised voice of the UK demolition industry. A video of the official ribbon cutting can be viewed at the web link: http://tinyurl.com/decwqd The new premises were acquired and

developed with the industry’s training needs to the fore. A dedicated training room, named after the late Sidney Hunt Snr and equipped with an advanced interactive whiteboard donated by plant distributor Marubeni-Komatsu, provides a superb environment for theoretical, classroom-style training. In addition, a separate enclosed and well-equipped area has been set aside for hands-on, practical training.

Elsewhere, the administrators that work on NFDC and National Demolition Training Group matters now have the space and facilities needed to handle the daily deluge of phone calls and emails from members. A new boardroom, which will be equipped with video conferencing technology, was pressed into immediate action, hosting an executive committee meeting as the last of the official opening guests departed. Before that, however, guests were treated to a guided tour of the superb new facility by NFDC chief executive Howard Button and his team. And in keeping with NFDC tradition, the event had a charitable dimension.

David Darsey presented a giant cheque for £23,000 to Howard Button’s daughter

Miranda for the Dwarf Athletic Association of the UK. This money was raised during last year’s NFDC Convention in Majorca with Darsey himself overseeing the impromptu auction. Also receiving a cheque for £5,000, was Liz Curtis, founder of the Lily Foundation, a charity set up in memory of Liz’s daughter who sadly died from the incurable Mitochondrial Disease aged just eight months.

Soff-Cut helps with new home for the Jets and the Giants The New York Giants and the New York Jets American football teams are building a new large home for themselves, the New Meadowlands Sports Complex. General contractor for the project is Skanska Construction. The entire outside area of the new stadium will be covered by sidewalks and is also need for the thousands of visitors that will enter and exit the stadium regularly. The subcontractor Commodore Construction Group is hired to perform the sidewalk cutting of the fresh concrete. In order to avoid and also repair cracks in the new concrete the subcontractor has chosen to use the Soff-Cut method from Husqvarna Construction Products.

Husqvarna Construction Products salesman in New York Bob Paccione says that the client is very happy with the Husqvarna/Soff-Cut equipment.

“The work is going very smoothly and the equipment performs very well,” says Bob Paccione.

Commodore Construction is cutting control joints in the sidewalks around the stadium with the Husqvarna/Soff-Cut 2000 and then chasing the joints with decorative scoring using the Husqvarna/Soff-Cut 150D. About 5,580 m2 (600,000 square feet) of green concrete needs to be cutted with a speed of some 2,290 m (7,500 feet) per day. The hardness of the concrete is estimated to be some 28 mpA (4,000 psi).

Facts about the New Meadlowlands Sport Complex

The New Meadowlands Sports Complex is an American football stadium currently under construction in East Rutherford, New Jersey. The new stadium will be opened for the first game of the 2010-2011 season. It will replace

Giants Stadium and is built in the parking lot of the current structure at the Meadowlands Sports Complex. As with the current stadium, both the New York Giants and New York Jets will play their home games there. However, unlike Giants Stadium, the new stadium will be a 50/50 partnership between both NFL teams. The stadium will be administered by the New Meadowlands Stadium Company, LLC. The Stadium is currently the most expensive stadium in the NFL. The new stadium will have seating for 82,500 fans, including 10,000 club seats and approximately 217 luxury suites.[3] It will be the second-largest or third-largest stadium in the NFL, after Cowboys Stadium (estimated 80,000 to 100,000 seats) and FedExField outside Washington, D.C., currently the largest stadium in the league with a capacity of 91,704.

Hilti acquires US Diamond B

The Hilti Corporation is entering the North American professional diamond service contractor market with the purchase of U.S.based Diamond B, Inc. on 30 June.

This move allows Hilti to enhance its global position as the choice provider of equipment and consumables for the professional diamond service contractor.

The strategic acquisition combines the excellent consumable products of Diamond B with Hilti’s innovative equipment. Diamond B’s expe-

58

rienced sales force accelerates Hilti’s entry into the North American diamond service contractor market through an established customer base.

Diamond B posted annual sales of $10.8 million in 2008. Both companies agreed not to disclose the purchase price.

The former owner and president of Diamond B, Webb Burnett, will retire from the business once the transition is complete.

Long-time Hilti employee Andrew Hunt, previously the head of Hilti’s Singapore market organization, will manage the new subsidiary.
