A new level for CSDA Training

special survey

Training and safety are steadily becoming more important to those working in the

sawing and drilling industry. No formal training or safety programmes were offered in the industry until the mid-90’s when the Concrete Sawing and Drilling Association introduced Cutting Edge.

Now, CSDA offers a range of training opportunities to meet the needs of the industry.

Cutting Edge was the first course introduced by CSDA for cutting operators in 1993 and has been transformed into an online course at www.csdatraining.com.

The online version has been very popular and complements a range of online courses, including a bundled package of video safety courses for flat sawing, wall sawing, core drilling, hand sawing and wire sawing. The online training makes CSDA training programmes available to a much larger population of operators who might not have been able to afford to attend a CSDA class in person. For company owners, these courses eliminate paper based testing, minimise training administration, provide tracking for all tested employees, maintain the safety of employee training records and cut down on administrative costs.

As convenient as online training courses are, nothing can take the place of an on-slab training class and CSDA offers those as well. Slab Sawing and Drilling 101, Wall and Hand Sawing 101 and Wire Sawing 101 courses offer those new to the industry hands-on training taught by experts with real experience with the latest in equipment provided by CSDA manufacturer members. These classes are held at CSDA’s training facility at St. Petersburg College and are also rotated

around North America to minimise travel for students. Some of these classes are also held during the annual World of Concrete exhibition in Las Vegas.

For experienced operators, the 201 certification courses allow them to become certified in one, two or all of the disciplines. The Slab Sawing and Drilling 201, Wall and Hand Sawing 201 and Wire Sawing 201 courses provide classroom and hands-on instruction, geared towards operators who want to gain top notch proficiency and productivity in these disciplines. These classes are offered at St. Petersburg College and at the World of Concrete.

Operators who want to advance to a higher level within their company can take CSDA’s Estimating course. This twoday classroom course is focused on the practice of estimating sawing and drilling jobs and is designed for employees with at least three years of experience in the concrete cutting industry and want to become estimators or those who wish to broaden their knowledge in the field of estimating.

Students have completed over 4,000 CSDA training courses and new courses are being added to complement the over 20 courses currently offered. In addition, CSDA complements the training programmes with safety manuals, videos and over 100 Toolbox Safety Tips. CSDA training programmes that were started less than 20 years ago have been very successful and the future will see an increased focus on training as CSDA moves to an even higher level.

Best regards Patrick O’Brien Executive Director CSDA, US Concrete Sawing & Drilling Association

Brokk, the Swedish manufacturer of remotely controlled demolition machines, has acquired Ahlberg Electronics, also from Sweden. The companies have collaborated for a few years and have now decided to join forces to further strengthen their presence within the nuclear industry. There are no organisational changes following the acquisition and the management of both companies will remain the same.

Ahlberg is known as the industry’s quality leader of radiation-protected camera and lightning solutions. The company is based in Norrtälje outside the Swedish capital Stockholm and has a global customer footprint. Ahlberg Electronics camera solutions are already used in more than 25% of the world’s nuclear power plants. “By becoming a part of the growing Brokk group, we can now accelerate the global growth of Ahlberg Electronics,” says Ahlberg Electronics chief executive officer Ulf Ahlberg. Ahlberg Electronics’ world-leading expertise for solutions in highly

radioactive environments is also a very good fit for Brokk machines in these environments.

Brokk and Ahlberg are well-known to deliver the highest quality products with industry leading performance and both companies are well established with customers worldwide. Brokk has delivered robots for demolition, decommissioning and disposal of radioactive material to the nuclear industry for over 20 years. Ahlberg Electronics has more than 30 years of experience delivering industry-leading camera solutions to the nuclear industry. “With the acquisition of Ahlberg Electronics, the Brokk Group further strengthens its position in the market for solutions in radioactive environments,” says Brokk Group chief executive officer Martin Krupicka.

Equipment from both Brokk and Ahlberg Electronics are used in the containment and clean-up work at the Fukushima nuclear power plant in Japan after the accident in March 2011.

The properties which render waste hazardous are laid down in Annex III of Directive 2008/98/EC and are further specified by the Decision 2000/532/ EC establishing a List of Wastes as last amended by Decision 2001/573/EC. The List of Waste is subject to continuous updates and is currently being reviewed.

This year’s EDA Convention on 14th to 16th June will be an ideal opportunity to get updated information about hazardous waste and how to deal with it. In order to discuss this and be able to learn more about it, a whole conference session about waste will be held.

During Intermat the owner of the Italian firm Trevi Benne, Luca Vaccaro, signed two exclusive trade contracts with firms in South America, which is witnessing considerable growth and expansion.

A distribution contract for the entire range of Trevi Benne’s products for the Chilean market has been agreed with the company Pesco in Santiago de Chile. In addition a trade contract for the importation and distribution of Trevi Benne products for the Colombian market has also been signed with Importadora Gran Andina in Bogotá.

Bauma is fully booked Waiting list for space, despite an extended exhibition area. Already 11 months before Bauma opens all space at the show is fully booked. This international trade fair for construction machinery, building material machines, mining machines, construction vehicles and construction equipment has a waiting list for all sections of the exhibition.

And this is despite the fact that the exhibition space allocated to the event has been extended to a record 570,000 m2.

For this event, the biggest trade show in the world, taking place in Munich from 15-21 April, 2013, a further 15,000 m2 of space has been made available in the north-west corner of the exhibition site. “With this additional space we can now admit more exhibitors than at the last event. Nevertheless it is still not possible to accommodate all those who want to take part, or to meet in full the space requirements of all participants,” says Messe München International Exhibition Group Director Georg Moller.

Bauma 2013 is well on track for exceeding the results of the previous event. At the last Bauma, in 2010, 3,256 exhibitors from 53 countries took part, and over 420,000 visitors from more than 200 countries.

Bobcat’s 25th Anniversary E16 Compact Excavator To mark the 25th anniversary of the Bobcat compact excavator range, a new Limited Edition of the Bobcat E16 1.6 compact excavator has been launched. It complements the new enhanced versions of the E16 and the 1.4t E14 compact excavators. Compared to the existing models, the enhanced E14 and E16 excavators feature new exterior styling. Inside the cab, the most important improvements are the new ergonomic travel levers and pedals used on the larger E26 excavator model. Optional features include a premium Bobcat radio, four tie downs, blade extension rubber pads, a new suspension seat and an auxiliary hydraulic line on the dipper stick. The E14 and E16 are powered by a 3-cylinder 9.9kW Kubota D722 engine. High digging performance is enhanced by the stability provided by the dozer blade and the machines’ low centre of gravity.

Words from the IDE President

“You get what you pay for” In these austere times in which we are all currently living, it seems that clients have all too readily abandoned the need for value in exchange for an almost compulsive clamour for the lowest possible price.

But in demolition, as in so many other walks of life, you get what you pay for. If a client searches long and hard enough, they can always find someone willing to do demolition work for a little bit less. But that apparent cost saving has to be achieved by the low cost demolition contractor somehow. Maybe his equipment is a bit older and more likely to break down, placing in jeopardy the client’s completion deadline.

Maybe his insurance is not quite as all encompassing as that of a higher cost demolition contractor, a fact that could leave the client carrying the financial can in the event of an incident. Or maybe the low cost contractor has skimped on the training of his staff, leaving the client to rely upon less experienced and less well trained operatives to deliver their important contract on time, on budget and without accidents or incidents.

The UK has just seen the introduction of a new British Standard for demolition BS6187:2011 aimed at improving industry standards across the country.

I am fully committed to any new legislation and guidance that might make the industry safer for its workers. But I am also mindful of the coverage of this new British Standard.

12

The new BS now includes refurbishment and partial demolition works, as it was apparent that the majority of ‘demolition’ accidents came from that sector. It is equally apparent that the primary reason for the poor safety record in the refurbishment sector is its general failure to use competent contractors and trained labour, with clients choosing to use the cheapest supplier at all times.

It is high time that clients understood the best way to ensure a quality job is to use competent and trained workers, and those demolition contractors and, in particular, members of the Institute of Demolition Engineers are highly skilled and bring added value to any project.

Indeed, competence is included in the new BS in Annex A.1.2.3. where use of IDE members is clearly stated, and is reinforced by Appendix 4 of CDM2007.

My message to clients is simple.

Appoint competent team members; look at quality before price; and then the demolition engineers will be able to turn your dreams into reality. Or, in the words of John Ruskin: “It’s unwise to pay too much, but it’s worse to pay too little. When you pay too much, you lose a little money - that’s all. When you pay too little, you sometimes lose everything, because the thing you bought was incapable of doing the thing it was bought to do. The common law of business balance prohibits paying a little and getting a lot, it can’t be done. If you deal with the lowest bidder, it is well to add something for the risk you run, and if you do that you will have enough to pay for something better.”

SIMA reduces lead times in Europe In Spain Granada based Sima has signed an agreement with logistics provider Dachser to set up its logistics centre in Nuremberg. This will enable European clients to take delivery of their orders within a maximum of 92h.

Sima’s agreement with Dachser will mean that Sima has a stock of machinery in Nuremberg to reduce lead times and optimise delivery service throughout the continent.

This new project has been running since January and delivery times since then have met targets. This success will help to achieve the 2012 export target of 75% of total sales.

The company expects between 60% and 65% of all sales for continental Europe to be shipped through the German logistics centre.

With this agreement Sima achieves its main objectives, to reduce lead times, optimise product transport costs for clients and offer a better overall service.

Until now, the European clients had to place orders with Granada, meaning longer delivery times and higher costs. The initial priority was Germany but it was soon observed that a single logistics centre could provide a better service to all of continental Europe.

Dachser with respect to delivery and tracking, Sima felt it was of interest to broaden its objectives to include all continental European clients.

Given the response to this project, Sima plans to open a new logistics centre in the UK to service Britain and Ireland, which do not receive deliveries from Nuremberg.

EXCAVATOR DERB There was no shortage of product launches at the Intermat exhibition in France with the excavator segment leading the way. All the main players competed for visitors’ attention with their latest controlled demolition and material handling machines. PDi’s Andrei Bushmarin reports from Paris.

The excavators showcased at Intermat may have different brand names and colour schemes, but they all share a few common features. First off, the new machines are powered by the engines that meet the Stage IIIA/B standards. With emission control regulations becoming increasingly stringent the world over, engine emission parameters are now of paramount importance for manufacturers and users alike. Also, the new excavators boast improved fuel efficiency and increased productivity over their forerunners. And their cabs have been redesigned to offer a whole new level of operator comfort. Countless gadgets and comfort options from cameras and MP3 players to heated air-suspension seats and fully automatic climate control, make operation as pleasant and easy as driving a luxury car, while ROPS and FOPS systems guarantee operator safety.

Komatsu makes a Dash for it At Intermat, Komatsu debuted the PC240NLC-10 excavator from its latest Dash 10 demolition range. Robust and versatile, Komatsu Dash 10 demolition excavators combine power and safety with enhanced fuel efficiency and low cost of ownership.

As standard the machines come with the heavy-duty 9mm undercover and 15mm side guards to protect them from critical damage. Reinforced side links and an optional cylinder guard add more strength and security. A top and front guard protects

the excavator from falling debris, while the laminated glass roof window, with a wash wipe, help maintain good visibility.

The operator can select up to six working modes to match machine performance to the application. These are power, economy, heavy lift, breaker and attachment power and attachment economy modes. The new attachment economy mode allows attachments to be used without compromising machine efficiency. A standard rear view camera lets the operator see behind the machine. New on Dash 10 is an optional camera on the machine’s right side; so both the rear and side views can be simultaneously displayed on the monitor. Two additional hydraulic circuits are fitted to allow use of rotating demolition grabs and crushers. The excavator is tuned for a hydraulic quick coupler, with a possibility to pre-set and name up to five different attachments and five breaker custom settings.

Caterpillar 349E - a fuel-efficient solution The new Cat 349E hydraulic excavator boasts many improvements on its predecessor 345D, particularly in terms of fuel efficiency, output and operator comfort. The new machine features a 317kW Cat C13 ACERT engine that meets EU Stage IIIB emissions standards. The 349E delivers more engine and hydraulic horsepower, while consistently averaging 5% improved fuel efficiency in typical applications. The 349E is equipped with a number of new fuel saving features that help reduce the cost of machine ownership. Among them is the engine idle shutdown setting, which defines how long the machine is permitted to idle before shutting down. A one touch idle control reduces engine speed to low idle with the touch of a button, while a second touch or a joystick movement puts the engine back into high speed. Isochronous speed control, which is a system that maintains constant engine speed, regardless of load, further conserves fuel, as does the 349E’s economy mode when used during less demanding applications. Operator comfort has been enhanced with a larger LCD monitor, the seat with heated and air-cooled options and climate control with positive filtration outlets.

JCB has upgraded its excavator range with the JCB Dieselmax 444 engine, which is said to deliver up to 24% improvement in fuel efficiency. Five tracked models have been fitted with

PDi • Issue 2 • April - May 2012

BY AT INTERMAT the new engine, and the 15t JS145W and the 17t JS160W wheeled excavators will soon be powered by it too. The Stage 3A/Tier 3 JCB 444 Dieselmax engine delivers up to 23% more torque, its response time is much shorter and, in the case of the JS160 and JS180 models, the engine operates at lower rev/min, up to 10% lower, thus increasing the overall efficiency of the machine and lowering noise levels. JCB has also redesigned the cab across its excavator range. Following the customer feedback, the split between the top and the bottom glass sections has been lowered by 125mm to a 70/30 division to provide the operator with improved visibility of the working area. The front upper corner of the cab has been shifted forwards to accommodate a flat glass panel, instead of curved glass. This makes replacement much easier and less costly. Other cab improvements include a scratch resistant roof glazing and a more spacious storage area behind the operator’s seat for tools. From now on, the ROPS and FOPS features will be an integral part of the redesigned cab.

Case unveils a slew of new models Case Construction Equipment used Intermat to introduce a further seven models to its C series crawler range. The new machines powered by the Tier 4 Interim compliant engines are 10% more fuel efficient than their forerunner the B range. Case’s intelligent hydraulic system incorporates five energy saving elements. The boom energy save lowers engine speed during boom lower and swing operations, while the auto energy save system cuts engine speed when the joystick control levers are inactive. The swing relief control manages the hydraulic power distribution at the start of a slewing operation to provide the most efficient use of hydraulic flow and pressure.

The spool stroke control automatically adjusts the hydraulic pressure during digging operations. An idle shutdown control turns the engine off after a preset time has elapsed. Further improvements on the preceding B range include up to 5% shorter operating cycle times, a 6% increase in lift capacity and a 5% larger cab.

Two customised excavators from Liebherr Liebherr has delivered customised versions of its demolition excavators to two French clients. One, the demolition contractor Doyère, is mainly active in the Paris area, and, therefore, frequently faced with the task of working in the city centre where space is limited. Given this, Liebherr-France SAS has customised its standard demolition excavator R954C VHHDW to operate with modular moving parts. The modular concept involves the boom, a boom extension and the two dipper arms of different lengths. The idea behind the concept is to reach a computed working height without the demolition tools making contact with neighbouring buildings. The concept has been successfully implemented, and the customized excavator is now employed on jobs in the city’s busiest districts, La Defense being one example.

For another French customer, Cardem, Liebherr has fitted its R944C LC with a remote control option. It allows this model to be operated from a distance in highly contaminated areas or in the proximity of buildings that are likely to collapse. The remotely controlled excavator has been field tested for over a year and has proved its worth on a number of projects, for example on the demolition of a residential complex in Longwy.

METALLPULVER

Three Weeks To Take Off PDi’s new Asia Pacific editor Barbara Grace met recently with one of Australia’s most skilled concrete cutters, Super City Concrete Cutting at Darwin RAAF Base.

Jason Franken from Super City Concrete Cutting in Australia discusses the need for innovation while preparing a tender bid.

Willingness to think beyond prescribed tender documents positioned Super City Concrete Cutting in pole position to win a major tender at the Darwin RAAF Base in 2012.

Experience, machine fleet and flexibility While the company was well positioned to win the tender, based on their relevant experience, specialised equipment and ability to deliver difficult projects within tightly specified timeframes, the deciding factor that won the project was their ability to show flexibility and innovation.

Jason Franken and Alan Torrance from Super City Concrete Cutting demonstrated to the client the savings that resourceful application of specialised equipment could achieve; namely halving the estimated time required to complete the job.

The head project, assigned to Macmahon contractors at Darwin RAAF Base, involved removing an old fuel line and replacing it with a new one. The line lay beneath a 600mm deep concrete apron used by aircraft during refuelling stops.

“The existing fuel supply line was originally installed in 1964 and had come to the end of its servicebilty,” said Jason Franken. “As the fuel line needing replacement was under existing concrete aprons, we had to protect the integrity of existing aprons by sawing and drilling, rather than jackhammering, which would have damaged the remaining curtain aprons.”

Saving time and money Removing 4m long concrete valve block ends 600mm thick.

Originally, the tender documents identified a six-week programme for Macmahon to complete the upgrade works.

Super City differentiated their bid during the tender process by contracting to do their specified work package in three weeks, utilising proven methods and systems of work. This

provided Macmahon with a programme they could work with to remove and install the new fuel line within the six week schedule.

This effectively assisted in reducing downtime for aircraft and saving time, resources and budget.

“We were selected because of our previous experience with airport projects and the large horsepower floor saws we use,” said Franken. “But what really won us the job was demonstrating our ability to diversify in terms of meeting project deadlines and introducing systems of work that showed we could meet those deadlines.

Originally, the tender specified anchor bar dowel bar holes to be diamond core drilled, but due to the original programme of completing work within six weeks, the time required to complete this task would not have been achievable. We realised this during the tender stage and recommended the Minnich Drill System as an alternative. Production rates with this system are ten times those of conventional core drilling for this application.”

Sawing and drilling was a proven method to use on this project, as Super City could draw from experience with similar projects to demonstrate that this system was more economical and faster than conventional hammering techniques.

The project involved: • Five sawing units to cut an access trench 900mm wide by

740m in length across two areas of the refuelling aprons • Hydraulic bursting systems to break the concrete trench at 5m

lengths to assist with the removal and extraction of the sections.

•

A Minnich Dowel Drill Machine and operator to air drill 4,000 holes of 45mm diameter holes to a depth of 250mm for dowel bar installation and tie-in of replacement concrete to the excavated concrete apron.

“A bold move, but we knew we could do it” Commitment to undertake and complete the work in three weeks, was a brave move. This was achieved by a work force trained and proficient in the use of the specialised sawing and drilling systems unique to the construction industry.

“It’s always difficult to place a definitive time line on projects such as this,” said Franken. “Time allowances are generally based on previous works that are similar in nature, and you work out procedures to maintain a certain type of programme. So for this job we provided a programme of three weeks to complete the sawing, bursting and anchor bar drilling. We knew it was a bold move, but we knew we could do it.”

While contractors plan for variables, there are always unknowns and in this instance Super City had a few major ones to overcome. “You expect many jobs to be similar, but two jobs are never the same, and it only takes a couple of unforeseen events to take you by surprise and slow the whole thing down,” said Franken.

On this occasion one of the unknowns was the hardness of the Removing 4m long concrete blocks 500mm thick after they have been split with C9 Darda splitting cylinders.

Take and to H A few years ago the demolition robot industry changed. After about 30 years on their own Brokk gained competition from Finmac and Husqvarna.

Now the number of competitors has further increased, however, none are the size of Husqvarna. Has the new situation lead to a change in Brokk strategy? Brokk CEO Martin Krupicka and head of the company’s marketing communications, Eva Skinner provide the answers to PDi’s Jan Hermansson.

For many years, the Swedish demolition robot manufacturer Brokk was alone in the market to develop and manufacture remotely controlled machines and equipment. They could quietly refine their technique and develop their marketing strategy and profile their unique demolition method that was advanced and very productive.

30 years on their own Being “King of the Hill” has its drawbacks. Being without that competition from another manufacturer means that you do not have that challenge or it is hard to establish the fighting spirit that manufacturers have who are challenged daily by its competitors. It is also easy to unconsciously take customers for granted and that the customers for their part feel they do not get the service and support they desire. Being a single actor can also be a heavy burden to meet the demands of the market and further develop and promote their products and methods as the market grows. Brokk has ploughed the furrow alone for many years, but this all changed when first Finmac and then Husqvarna launched their remotely controlled demolition robots.

Brokk was faced with an entirely new situation after 30 years of solo driving the market forward. A new situation had come to stay. “Competition is something we all need.

Competition is what drives people and companies forward.

Together we can increase our knowledge of the actual demolition method, which allows us to broaden the market,” said Brokk CEO Martin Krupicka. “Getting new and talented competitors is the play of the game. It is something we must live with in our industry just like in most other industries.”

“The strategy is to take and maintain control” Krupicka says that Brokk has undergone a fairly extensive process of transformation over the past 10 years that they would have made regardless of the new competitive situation. The change started when Brokk’s former owner Sorb Invest was acquired by Lifco, which in turn is a wholly owned subsidiary of Carl Bennet. “Since then Brokk has had a clear and long-

term strategy and the development has been very favourable since Lifco took over the company,” says Krupicka.

Brokk has turnover of over EUR42M across the group and the profit is satisfactory and reinvested in the company for continued product development, marketing, expansion of the service organization and more. A key element of its strategy, which was introduced when Lifco took over, was to place more focus on Brokk in its marketing channels. “One way to increase our focus is to take and maintain control by owning. In our case we have in recent years focused more on establishing our own sales companies and we have come a long way,” says Brokk marketing communications director Eva Skinner.

Already in the 1990s, Brokk acquired its first subsidiaries, which was in the US and England. Subsequently Brokk acquired Darda in Germany in 2006. Then, in quick succession, Brokk formed Brokk Asia in Singapore in 2007, Brokk Australia in 2010 and Brokk Italia and Brokk France the same year. Last year they started Brokk China and Brokk Norway.

More products and focus on the method In parallel with the strategy to maintain control over the service and sales network, Brokk has fulfilled the goal to broaden the product range and replace it with new models. But not just the machines but also new tools for more applications.

“A Brokk can be used for much more than what it was primarily intended for. But to widen the application area new tools and machines have to be developed. And we are right on track now. In addition to our wide range of standard tools, we have launched drilling equipment, rotating milling heads, power cutters and more is on its way,” says Skinner.

The entire range of machines has been renewed with new control systems and extended since 2009 and currently consists of: Brokk 50 and 90, which is soon to be replaced

by Brokk 100, Brokk 160, 260, 330D, 400, 800S and 800P. “Our product line seems at present quite complete. Now we can focus on selling the right machine and tools for the right application and providing the right training and service solution. As always, we sell not only a product but also a method, the Brokk method,” says Krupicka.

To broaden the use of the Brokk is something that runs like a thread through the company and the machines’ versatility plays an important role in combination with the wide tool range, which will be further expanded.

The market In addition to its own subsidiaries, Brokk has more than 40 distributors and agents around the world. In the US Brokk finished with their independent representatives a few years ago and today all sales go through its own organisation. “We felt that for most of the many independent US reps as we had the Brokk business was too small for them to be really good at selling the Brokk method,” says Krupicka. “Salesmen who basically focus solely on Brokk not only have the knowledge required, but also an entirely different motivation. They have the right drive. Either the salesman succeed in explaining how the Brokk method is the best solution to a customer’s problem which surely will result in sales. If he doesn’t he is not going to sell anything. Its either ‘Brokk or bust’.”

Even Brokk has been affected by the sharp decline in the Tech Talk about the new Brokk 100. From the left assembler Åke Edström and designer Jan Hedlund.

US, but believes the market is about to turn upwards again.

Likewise, it has been slow in some markets in Europe, but on the other hand, it has been steaming on quite well in Asia, which has balanced the global sales. At present Brokk sales are fairly evenly distributed across the world.

It has now been a few years since Brokk had to compete with the two demolition robot manufacturers. “In the beginning, we experienced some competition, but currently I cannot say that we are aware of it so much. Maybe together we made the market bigger, who knows? It also appears that after all the news customers have come to the conclusion that they really appreciate the reliability that Brokk machines provide and that we have an extensive service network in place. Then I want to reiterate that we have a clearly developed strategy that we follow regardless of whether the competition has changed or not. This strategy points out how to become a better and stronger player in the market and a better choice for our customers,” says Krupicka.

Krupicka also emphasizes the company’s owner Lifco is also an important part in the Brokk success. Although Brokk is a rather small but still profitable company in the group, the company provides its owner with a lot of money for further product development. “I feel very secure with Lifco, which is a stable owner and ultimately Carl Bennet’s long-term perspective of Brokk’s continued development,” says Krupicka. “But our own capital, employees and all the knowledge available in the company is a treasure. We have over 30 years of experience and we have had time to make a

lot of mistakes along the way that we learned from. It’s hard to compete with that as a newcomer. In theory, it may look easy to build a robot, but it’s not in practice. This requires, in short, long experience, and we have it.”

QUICK AND AUTOM

Demolition and recycling contractors have a need to change tools frequently. Quick release systems where the operator has to leave the cab to manually remove and connect pins and hydraulic hoses are too time consuming. But today there is a small number of automatic quick coupling systems where everything is handled automatically in just seconds. PDi’s Jan Hermansson has checked out the new and existing systems.

OilQuick in action.

As the need to switch tools often has increased also the demand for efficient quick coupling systems has increased.

Frequent changing of tools on the machine with manual quick coupling systems is cumbersome, time consuming and inefficient. In traditional construction, the problem is not that big when tools are not changed too often. But in the demolition, recycling and scrap industries tools are changed frequently and today efficient quick coupling system are crucial. On a demolition job the operator needs to switch between different tools quickly. He may break or tear with a hydraulic hammer, cut with a concrete crusher or shear, pulverise with a pulveriser and sort and demol-

ish with demolition and sorting grab, screen and recycle with screening and crushing bucket and mill with rotating milling head. Often several of these tools are used on one single work site.

“Stay in the cab” Just a few years ago, tool changes were a laborious and time consuming process. The machine operator had to leave the cab to release the tool, disconnect hoses, adjust the position of the machine and tools and then attach the new tool with all that that entailed. The work was frequently associated with oil leaks, damage to the equipment and injury to the operator. In cold and bad weather tool changes can be especially tricky. Because of the extensive work of replacing attachments many operators used the wrong tool for the job.

Over the past 10 years a small number of manufacturers have emerged that specialise in manufacturing flexible systems to quickly and easily change hydraulic tools almost automatically in a few minutes, or even seconds in certain situations. The objective is for the operator not to leave the cab during the quick-change process. An important advantage of these so-called automatic systems is the absence of oil leaks during the changeover.

Despite the advantages of quick release systems, manufactures still have difficulty convincing demolition contractors of their benefits. “Everybody in this business knows that manual tool change is a nuisance and that the task takes a lot of time. Although automatic quick hitch systems cost a bit to buy, you don’t need an advanced equation to find that it pays,” says OilQuick owner and director Åke Sonerud “To think a little longer and invest in an automatic quick hitch would mean that the machine and tools could be used up to 50% more. There’s a lot of money in one year. An OilQuick system pays for itself in two to three months.”

Many talk about automation and to minimize roll times in the demolition industry, but this thinking has not quite taken hold. The quick connection is almost as important as the tool. Approximately 5% to 7% of the cost of a demolition excavator equipped represents the cost of the automatic quick hitch system, which increases efficiency by up to 50%. The increase represents improved efficiency, better control, more precision and smoother work for the operator, more satisfied customers, increased competitiveness and significantly improved profitability.

The security and safety is improved because the operator sits in a safe environment.

Another advantage is that it also saves the tools.

With quick and easy changes the right tools are used. “A good example of payback for a quick coupling system like OilQuick is for the need to change tools twice a day on a 35t machine, the system will soon pay for itself,” says Sonerud.

OilQuick automatic quick couplers “As I see it, all demolition contractors need to quickly change between different hydraulic tools to increase efficiency and, in short make more money. Many demolition contractors still do not know what benefits OilQuick can offer them, but we are working hard on changing that,” says Sonerud. “We really sell a rationalization tool more than a quick coupler.”

The new Cat® Auto Connect System for all types of hydraulic demolition and recycling attachments.

OilQuick launched its first quick-release coupler in 1993. Since then OilQuick has evolved and expanded to accommodate the growing number of carriers. Now the OilQuick automatic quick coupling system fits carriers between 2t to 120t in nine standard models for excavators and a number of quick couplers for wheel loaders, cranes, forklift trucks and material handlers. The company also manufacturers a wide range of OEM models specifically designed for the German Kiesel Group. Kiesel is the sole distributor for Hitachi in Germany and have the sales right for Fuchs Material handling machines in 15 countries around Europe.

Almost from the start Oil Quick began profiling its system towards the demolition industry. In the early 1990’s it became increasingly common with concrete crushers and pulverisers and towards the end of the decade also demolition grapples. Breakers by contrast had existed for a long time. “But it was only towards the end of the 1990s, that sales to the demolition industry really took off,” says OilQuick chief executive officer Henrik Sonerud.

Strong demand in Central Europe In recent years, the demolition industry around Europe began to realise the benefits of OilQuick. Central Europe with Germany and the Alpine countries perhaps embraced OilQuick most of all and are very open to the concept. Several large contractors have invested in OilQuick systems for all their machines. But also in Scandinavia OilQuick’s systems are becoming popular with demolition and recycling contractors.

Sales of the system are focused on Europe, but OilQuick is beginning to establish the brand in other markets such as Canada and Illustration of the OilQuick automatic quick coupler.

MATIC the US. “In the US it is still very common to use a machine per tool. You often see a lot of machines in the workplace.

In addition, they still use a lot of mechanical tools. But slowly but surely, we’ll convince the Americans too. The sales in the US and Canada are handled from our office in Canada. We now have our own people there,” says Henrik Sonerud.

Currently OilQuick has an annual turnover of approximately EUR15M with 31 employees.

The export share is around 80%. It has 15 dealers and service centres around the world and holds regular training classes at retailers and at their headquarters in Hudiksvall, Sweden. “We have a good pace even though the recession has reduced the pace a little bit.

The outlook is bright and our goal is to double our sales over the next three years and triple it within five years,” says Henrik Sonerud. “But to double and triple our revenue depends on getting our message to our users. Using conventional systems actually means that the contractor loses money every day he drives ahead with that arrangement. With OilQuick it is the exact opposite.”

Caterpillar’s new automatic quick coupler A new automatic quick release system has recently been released on the market. The product is called Cat Auto-Connect Quick-Coupler and was launched at Intermat. Auto-Connect is a new generation of automatic quick couplers for excavators, which automates tool change, enhances productivity and an excavator’s applications. The operator can safely and comfortably sit in the cab to make the tool change.

The new system is based on Caterpillar’s traditional and field-tested quick connection technology, CW-platform. There are many benefits with the new system, which facilitates not only the quick tool changes without eliminating unnecessary down time. Thanks to the design of the system it reduces unnecessary stoppages, like bursting of valves and oil spillage.

“Caterpillar has been making high performance machines for 85 years, and our standard Quick-Coupler CW platform has a European heritage stretching back over 35 years. The new Auto-Connect is based on that same platform to help our customers get more out of their machines and work

Seals on both the quick-coupler and the work tool cover have been included to close the gap with the cartridges, ensuring full contamination control. Rigid work tools without hydraulics, such as buckets, do not need conversion to be picked up by the Auto-Connect quick-coupler.

Safety Built-In User safety is paramount in the design and construction of the Cat Auto-Connect quick-coupler, which is fitted with a check valve for maximum safety to ensure that the Auto-Connect maintains its work tool, even in the event of a hydraulics failure. Operators will be safer with no hoses with hot oil flowing through them to change, and more comfortable as there is no need to leave the cab to change tools.

Plug-and-Perform System Auto-Connect is a plug-and-perform system based on Caterpillar’s dedicated CW platform that fits directly to the machine and its existing controls. The Auto-Connect is controlled through the quick-coupler actuation circuit.

Combined with Cat Tool Control, it is easy for operators to select tools and make fast changes. With features like Auto Depressurization as standard, no additional hydraulic components are required.

High Flexibility The new Cat Auto-Connect coupler maintains optimum breakout force because the geometry in the relationship between the work tool and the boom is not changed.

It supports up to five hydraulic ports depending on the

With near instant tool exchange, operators will be encouraged to use the right tool for the job every time. The tool lasts longer, working practices become more efficient and fewer machines are needed to do the job, improving the total return on investment.

The new Cat Auto-Connect quick-coupler with integrated hydraulic connections presents several benefits: • Safe, secure and quick coupling of hydraulic connections • Operated from the cab • The hydraulic system cannot get contaminated • No need to re-route hoses • Protected when operating a non-hydraulic work tool.

also be used for machine tools and the system detects the type of tools to be used. A quick-release bracket is suitable for all types of hydraulic excavators from over 12t. The system can also be connected with oil pressure running.

Oilmaxx Oilmaxx automatically switches hydraulic tools in one step and with the operator seated in the cab. The structure and operation of this system are broadly similar to A Lock Oilmatic, but the Oilmaxx system is intended for machines up to 38t. The system can be used for tools and hydraulic tools with the so-called W-Lock adapter without conversion. The system is easy to work with and easy to close and open.

Oilmaxx V8 Easy, quick and automatic with Cat® Auto-Connect.

Wimmer The Austrian manufacturer Wimmer, based in Thalgau, has long been known for its production of various types of machine tools. It has also been making quick coupling systems. The hydraulic quick coupling products are also manufactured as OEM for the German manufacturer Liebherr. In Wimmer’s range there are currently three different model groups, which are the A-Lock Oilmatic, Oilmaxx and Oilmaxx V8. All systems offer fast, easy and automatic replacement of the hydraulic machine held tools.

A lock Oilmatic A-Lock Oilmatic has a new feature to easily connect even the electrical connection, such as tools with magnetic valves. The system identifies the tool automatically and enables waste oil separators and automatic pressure equaliser.

The system’s switching mechanism is placed so that it is protected from dirt and damage. A two-step sequence during the tool change protects the hydraulic connections. SPS control and so-called oil tuning are available as an option.

Hydraulic valves, which are protected, are designed with a non-drip system. The whole system is maintenance free.

The system has a coupling mechanism for one to two hydraulic circuits and can be operated from the cab. It can

The system is suitable for machines that are equipped with Verachtert adapter, without the need to be modified. Hydraulic connectors are located in the bracket to prevent damage. When the tool is locked or unlocked, a signal sounds. The system is intended for machines in the weight class 15t to 40t. The design has been made very compact, with an integrated switching mechanism.

Verachtert Connect’o’maat From the Netherlands is the well-known Connect’o’maat system that has been developed and manufactured by Verachtert, known as a manufacturer of various types of demolition tools. Their automatic quick release system is specifically designed for demolition and recycling applications. The system is fast, efficient and easy to work with and with a sleek and compact design.

Verachtert provides a separate cotter adapter for mounting a bucket directly. For demolition and sorting a system has been designed so the operator can reach the equipment easier. The attachment points are also available in bolted end caps with universal perforated pattern. The tilting Connect’o’maat CWT model is an addition to a flexible and versatile fleet of machines. With the two doubleaction cylinders, this product can be tilted at 40° in either direction. The tilting Connect’o’maat is usually a wedge / wedge model. This means that the CWT can be strapped

on and off easily from the fast-acting seal and the bucket.

The advantage of the Connect’o’maat CWK model is the unique power tilt actuator. The power tilt is available in many markets and is an ideal tool for excavation. CWK ensures an inclination angle 65° in either direction. Driving on slopes and preparing the surrounding area is now easy for this machine.

The newest developments in optimum manoeuvrability lead Verachtert to the inclined and rotating connect’o’maat. This is a joint effort with Engcon from Sweden. This equipment is also equipped with an original Verachtert Connect’o’maat and connections for the domestic market. The third generation quick connect system is equipped with two double-action cylinders, and an external leak-off pipe is not required.

Coupfix The German manufacturer Riedelberger, based in Schiltberg, makes the automatic quick coupling system Coupfix.

The company makes a number of different quick couplers for a large variety of attachments but also has automatic quick coupling systems for demolition and recycling.

Riedelberger is making a number of OEM models for manufacturers like Liebherr, Volvo, Wimmer, Verachtert and Lehnhof.

Engcon At the Swedish show Maskinexpo in May the Swedish manufacturer Engcon introduced its first automatic quick coupling system called EC-Oil. The system is currently designed for small and medium-sized machines. The system comes in sizes S45, S60, S70 and sometime this year will be joined by the S80.

A growing family The new HF system SW800E from Dr Schulze.

Valuable meetings at Husqvarna training centres Punctually for the beginning of the current building season the German company Dr. Schulze from Wilnsdorf, which manufactures a range of machines and diamond tools at four sites in Germany and has a world-wide sales network, extends its delivery programme on high-performance wall saws with a new machine with high frequency drive.

The new SW800E The new SW800E from the Profi-Center Meissner is based on the approved hydraulic version of the SW 800, which has been in worldwide use for three years. The SW800E has some characteristics with this model in common, which make the use of the machine very comfortable and increases productivity. These include, self-adjusting maintenance free guide rollers, a 360° rotatable swivel arm, precise and easy ball bearing of the blade guard as well as central cooling water supply.

The hydraulic SW800 has convinced its buyers by two characteristics of an innovative fully automatic feeding, which drives the cutting speed load depending, and by its reliability. These characteristics stood in the main focus in the development of the electrical SW800E. The heart of the new saw is the new and self-built PowerBox HFB180. Some of the main characteristics of this system are the external and less sensitive cooling, the stainless steel housing with vibration-cushioned feet, automatic detection of different HF-motors as well as special high speed plug connectors for all kind of cables.

PowerBox components and for the HF motor, as well as a multi-level overload protection of the whole HF drive.

The operator of the machine is free to move on site and can chose a safe view of the cutting to a new wireless remote control with optical current load control with overload warning. The remote control can be charged from a car’s power supply. A further characteristic for the operator is fully automatic control, which regulates the feed and lowering speed of the machine, protecting the saw against overloading. Experienced users can deactivate the mechanism and use it in manual mode and for transport to and on site the PowerBox HFB180 can be installed onto an optional carriage.

The cutting head of the machine is equipped with a quick release system for electrical and hydraulic motors. The motor change is handled in just a few seconds. The SW800E comes with an HF motor HFM160S, which supplies an output of 16kW and has an integrated two speed gearbox for maximum torque available for all diameters of cutting blades.

The manufacturer offers an optional system for flush cuts, which consists of a quick-change flange that can be installed in a few seconds onto the cutting shaft, together with the cutting blade, and flush protective covers in different sizes.

A group of cutting and drilling professionals from France visited Husqvarna’s training centre in Jonsered in March. Husqvarna regularly invites customers and users to the company’s training centres. One of them is in Jonsered, just outside Gothenburg in Sweden. The spacious facilities are well suited for demonstrating new products and innovations.

“I appreciate to get to know Husqvarna and their products better. I also appreciate that Husqvarna is interested in getting to know me as a customer better,” says French construction company Fora managing director Guy Josserand, who was one of the participants in a group of French cutting and drilling professionals. The group included customers of Husqvarna and contractors that had no previous relation with the company. Several of the participants were members of the French drilling and sawing association, SNED. Husqvarna’s training centre in Jonsered is about 20km outside Gothenburg. Husqvarna Construction vice president Anders Ströby, welcomed the group before the demonstrations began. The visitors were divided into two groups that could see the products in action and testdrive the demolition robots, high frequency wall

saws, surface preparation equipment and drilling systems. Product specialists from Husqvarna did the demonstrations.

A highlight of the day was the automatic drilling system AD 10. It is one of the fastest automatic drill feed units in the world, and makes drilling work faster and easier, enabling users to produce more over a shorter time with less strain.

The powerful, high frequency wall saws also generated a lot of interest. Equipped with new electronics, new lightweight blade guards and an easy-to-use remote control, the saws offer high productivity and efficiency. “I’m particularly interested in the wall saws and the drill system AD 10. The technical features of the AD 10 open up new possibilities with drilling,” said Guy Josserand.

For Husqvarna, it’s of great value to demonstrate the product range on the company’s own premises.

“To meet with existing customers and potential customers is very valuable for us. We receive important feedback and we can explain and discuss our products and systems in detail,” says Husqvarna Construction France heavy users sales manager Pascal Quignon.

“Don’t disturb the sharks” In the UK a Plymouth driller was given a once-in-a-lifetime warning on his latest job of ‘Don’t disturb the sharks.’ Diamond drilling and concrete sawing company D-Drill was called in to help create a new viewing area at Plymouth’s National Marine Aquarium. The company had to cut out an 8m block wall beneath a tank containing Sand Tiger Sharks, five Nurse Sharks and ten Southern Stingrays.

Because of the sensitive nature of the creatures, the decision was taken to use a quiet, vibration-free method of chain sawing. “We would have usually used a drill or breaker to remove the wall but, because we had been asked not to disturb the sharks and other animals in the tank, we looked for the best possible method,” says D-Drill Plymouth office manager Edward Taylor. “Sharks, we were told, could become

very spooked by loud noise, and particularly by vibration, so our priority was to carry out the work without distressing them. Nobody wants to upset a shark, even if it’s inside a tank. The operation was a complete success and proved that it pays to call in a specialist when this type of work is needed.”

James Wright from the National Aquarium thanked D-Drill for their attention to detail.

“Our highest priority is the standard of care that animals at the Aquarium receive, which is always an important consideration for us,” said Wright. “D-Drill were extremely professional, fully understood the issue and went out of their way to ensure they completed the job with absolutely no disturbance to any of the sharks and other animals in the tank.”

Expansion requires retrofit by the Nuremberg water management office To achieve a new, full-value floor in the office building of the Nuremberg water management office in Germany, the existing sixth floor must be retrofitted.

For this work, Plannerer Holding in Pullenreuth was contracted as the demolition company.

Before increasing the height, the reinforced concrete flat roof had to be removed with 3% incline and cut into smaller pieces. To achieve this, Plannerer used two Lissmac floor cutters; a hydraulic diesel FA Uni-Cut floor cutter and a high power compact electrical FS 22 E/FU floor cutter.

With saw blade diameters from 800 to 1200mm, the 410mm thick flat reinforced concrete roof, plus 50mm insulation, was cut into 2.3m by

5.8m parts. For this, Plannerer used saw blades especially suited to the material. The 6.5 to 9t individual parts were then lowered with an 80t Sennebogen crawler crane from the building roof.

Due to strict building plans, work was done under severe weather conditions. Permanent frost with temperatures down to -12° C caused the cutting water to freeze again and again after short breaks. The cutting slurry was taken away with the adapted Lissmac waste water suction. The retrofit of the entire 22m by 15m floor was successfully completed within 6 weeks in several construction segments.

As demolition contractors demand more from their equipment, manufacturers rise to the challenge. PDi’s Jim Parsons reports.

If concrete pavement, bridges, and buildings were not meant to last, demolition would be a relatively simple process. Indeed, it might prove more logical to let nature take its course as these structures wear out and whither away on their own.

Built for the task Of course, durability and strength are the very reasons why concrete has been so prevalent in construction for generations.

But it has also created an interesting paradox; the more engineers improve upon concrete’s inherent qualities to give society safer, more reliable buildings and infrastructure, the more brute force is needed by demolition contractors to repair, modify, or remove them. That is why breaker manufacturers have designed and crafted products to tackle the broadest range of concrete demolition challenges, from the simplest pavement sections to vast, hardened structural complexes. Along the way, manufacturers have incorporated refinements so that these machines can more easily and efficiently flex their mechanical muscles, while also using fewer resources to operate and maintain.

The intent is not to foster a Cold War-like arms race between designers and demolishers. Rather, it is to make sure that contractors always have the best technology and tools at their disposal. Just as concrete is not necessarily forever, contractors in the current competitive marketplace must continually prove themselves to time and budget conscious customers. It is one thing to be able to say, “we can do it.” But it is the value of the products in the following report that makes it possible for contractors to say, “we can do it better.”

New hydraulic breaker HB 4100 from Atlas Copco Atlas Copco presents the new hydraulic breaker HB 4100, which scores points in comparison with its predecessor model with less weight, better performance, and higher efficiency.

“Both in terms of performance and efficiency, the improvement in comparison to the predecessor model is considerable,” says hydraulic breaker product line manager Gordon Hambach. “Here, we were able to achieve increases in the double-digit percentage range.”

Reduced weight and better performance of a hydraulic breaker means that similar results can be achieved with a smaller hydraulic breaker. A lighter breaker also means that a smaller excavator can also be selected, saving investment and operating costs.

“The follow-up costs of an investment in a hydraulic breaker are many times greater than the pure acquisition costs,” says Hamback. “The reduction of these total costs of ownership involves the conserving of resources, such as energy and work time, as well as durability and simple maintenance concepts.”

With a weight of 4.1t, the HB 4100 is suitable for carrier machines from 40 to 70t. All proven features of the heavy hydraulic breaker series from Atlas Copco are also found in the new HB 4100. Among them are the VibroSilenced system to protect operators against noise and vibrations; PowerAdapt, which switches off the breaker in the event of a hydraulic overload; AutoControl, for the adjustment of the blow frequency and blow energy to the hardness of the stone; and ContiLube TM II, the integrated, automatic lubrication apparatus.

With StartSelect, the operator can influence the start-up

Cat® E series hammers feature enhanced durability, reliability Caterpillar has introduced four E series hammer models, the H110Es, H115Es, H120Es and H130Es for use on small and medium excavators, and on the Cat® 450E backhoe loader. E series hammers are wholly designed, engineered and manufactured by Caterpillar, making Caterpillar the only global hammer and carrier manufacturer. The four E Series hammers replace the H100s, H115s, H120Cs and H130s.

E series hammers feature a new symmetrical housing design, which allows rotating the housing 180° to compensate for wear, effectively extending the life of the housing. The lower portion incorporates rock edges that add protection to the housing in abusive applications. And, an optional wear package is available to further enhance hammer durability in severe applications.

The new housing is built for strength and lowers life cycle costs. A sleek, curved front and back profile eliminates stress points and transfers forces to the bottom of the hammer.

One-piece side plates eliminate the centre joint and weld. The hammers are fully supported by Cat dealers, enabling customers to work with a single organization for machine and work tool parts and service.

E series hammers build on Caterpillar’s proven D series features, such as automatic shutoff, which instantly stops the hammer when the tool breaks through material. The system

increases hammer reliability and durability by eliminating the high internal stresses created by blank firing.

Another feature continued in each E series hammer is the external pressure control valve, which reduces service time when an adjustment is necessary. Sound suppression is standard for environmental protection and improved operator comfort.

To the left a new breaker from Promove.

Below Montabert marketing director Alain Carbonnel showing the company’s new automatic two speed breaker, V3500.

Designed for use on the company’s compact loaders and mini and midi excavators, the nine models in Bobcat’s HB series of hydraulic breakers offer high performance, greatly reduced maintenance, and ease of use.

Designed for trenching, concrete demolition, and general excavation work, the Bobcat breakers feature a frame with a cylindrical design, providing improved access to jobs in confined areas such as inside structures or holes. The breakers’ standard equipment includes 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, ensuring a longer working time without risk of overheating. The breakers also incorporate a very effective soundproofing system, whereby the striking assembly is held top and bottom by suspension systems that are not in contact with the outer cylindrical housing.

In addition, the breakers present a novel internal design with fewer moving parts and no tie rods. As a result, the breakers can be completely disassembled in less than five minutes without the need for special tooling, reducing maintenance costs even further.

The HB series also 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.

All HB breakers feature: •

• • •

Versatile mounting allowing use on both Bobcat compact loaders and excavators Silencing as standard Fewer moving parts for easy and minimal maintenance An automatic pressure-regulator that ensures the breaker works at its optimum operating pressure on all approved carriers

Another innovative feature is a patented treated steel ring clip system that retains the bushing of the tool and protects the greasing system. This ring is easily removed with a multi-purpose tool supplied with the breaker to release the sliding bushing and the tool instantly.

Promove debuts 2t hydraulic hammer Intermat 2012 was the setting for the debut of Promove’s new XP2000, a 2t hydraulic hammer, specifically designed to fit excavators in the 22t to 32t class. The new model offers significant improvement in breaking capacity for machines in the 24t to 25t class, while it will be a lighter alternative for 28t to 30t excavators.

Rammer branded products return Rammer, the brand synonymous with hydraulic hammers and attachments, is set to make a welcome return as Sandvik Construction announces a multi-brand strategy. Through the reintroduction of Sandvik owned Rammer branded products Sandvik will be able to serve a wider customer base through the use of differing breaker focused distribution channels.

The Rammer brand was withdrawn in 2007, when the entire Breakers Lahti product line came under the Sandvik Mining and Construction umbrella. As a key part of the Sandvik brand the Breakers Lahti facility has remained at the forefront of hydraulic breaker innovation, directly benefitting from Sandvik’s experience and knowhow. In recent years the entire product range has been updated, with all developments benefitting from customer need based designs and solutions aimed at maximizing the uptime of the unit. Now, however, the Rammer name is to be reintroduced

by Sandvik in a move that is a unique part of Sandvik’s new multi-brand strategy.

Despite the benefits of being part of the Sandvik brand the reintroduction of Rammer branded products has been based on customer demand. “For more than 30 years Rammer enjoyed a level of brand loyalty that is virtually unique in the field of construction equipment.

And that popularity has never decreased,” says PA Breaking vice president Ola Ulmala. “Our hydraulic hammer and attachment customers in the construction, demolition and quarrying sectors let us know that they would welcome the return of the Rammer brand, and, as a customer-focused

company, it is our duty to give those customers what they want.”

The return of Rammer branded products will be welcomed by equipment owners and operators across the globe, as over the years the Rammer brand set the benchmark for many of the key innovations, many bearing the company name, that helped shape the hydraulic hammer business of today. These developments include: •

Ramdata - The on board service indicator, which provides on field information to the user, as well as stored data for use by the owner and dealer to ensure optimized use of the unit.

•

Ramlube - Automatic lubrication system designed to ensure a long, trouble-free life developed specifically for hydraulic hammers.

•

Ramona - Remote monitoring analyser that utilizes advanced electronics within the hammer hydraulic system in order to deliver up-to-the-minute condition and performance data to the operator, thereby identifying abnormalities in operating conditions and pre-empting potential catastrophic failures before they occur.

Following the rebranding Rammer-branded hammers and attachments will be available through existing sales and distribution channels. This will apply mainly to customers in the construction, demolition and quarrying sectors mainly through existing distribution channels. For customers within the mining or large quarrying sectors, or requiring breakers as part of a Sandvik turnkey package, fully supported existing Sandvik branded solutions and arrangements will remain mainly served through direct channels.

Breaking the way to new development Pomgrad, one of the oldest construction companies in Croatia, is participating in the massive effort to upgrade and modernize the facilities and infrastructure of the country’s scenic west coast near Split. In addition to a new Hilton hotel, the project includes 150m of public benches in the pedestrian zone, and 550m of underwater lighting along the coast; a two-lane road; marina; public square; and other amenities.

The project team’s main challenge was the construction, transport, and installation of huge concrete blocks, designed to break the waves and protect boats that will moor in the marina. To fa-

cilitate the excavation process, Atlas Copco’s new HB 3600 breaker was put to work breaking large underwater rocks to the necessary depth and prepare the foundations for the concrete blocks.

An unexpected challenge was an incorrect estimate of the ration of mealy and concrete rock under water. “It was estimated that we will have around 4,500m3 of concrete rock while in the end it was close to 10,000m3,” says project manager Ante Milacic. “The HB 3600 solved that problem quickly because it’s good for underwater work. So far we haven’t had any problems with it.”

New Sandvik breaker helps Seda Construction with aggregates for dam project The new BR4099 breaker from Sandvik has recently helped Seda Construction break boulders and large pieces of quarried rock as part of the prestigious Kopru dam project in the south of Turkey.

Aggregate was required for the construction of derivation tunnels as part of the project, and it was deemed most practical to use quarried stone resulting from the excavation process of the dam as the source for the aggregate. The problem in using this convenient, cost-effective, and environmentally friendly source of material was that it was often still in boulder form, making it too large to use as an aggregate.

The solution was close at hand with the Sandvik BR4099 hydraulic hammer. Through its research and development programme, Sandvik has produced a new operating principle that allows the BR4099 to be purpose matched to individual applications, and materials using a simple working mode selector located on the breaker. The highenergy mode utilises a lower blow frequency for optimum breaking power when working on hard material, such as granite and reinforced concrete foundations. A high-frequency mode delivers a higher blow rate and reduced impact energy to break softer materials, such as limestone. The Idle Blow Protector works regardless of working mode to provide greater levels of protection.

Sandvik’s BR4099 has been designed for a long, trouble-free working life with simplified, yet robust hydraulics that enable the machine to be comprised of fewer valves and greater back pressure tolerance, making it the ideal match for a wide range of carriers and hydraulic flow rates.

The BR4099 also benefits from the use of long life, vibration dampened tie-rods for improved reliability, extended service periods, and lower operating costs. A new, more robust front head has been produced using new manufacturing techniques and features fewer holes to relieve stress.

For greater flexibility in the field, the tool retaining pins are locked by simple, yet reliable rubber rings, while the surface of the lower tool bushing has been specifically designed to provide longer tool life.

To further extend its working life, the BR4099 may be supplied with a choice of three greasing options: a centralized manual option; carriermounted Ramlube I automatic greasing; or Ramlube II, which utilizes a cartridge mounted on the breaker to automatically deliver optimum levels of lubrication for greater wear protection and longer operating life.

Seda Construction has expressed total satisfaction with the performance of the BR4099, as well as the support and advice from local distributor, Alfatek. Seda soon became more than proficient

in the use of the BR4099, and was particularly impressed by the BR4099’s ability to deliver massive impact energy with high blow frequency. The

work accomplished by Seda Construction on the Kopru dam project has proven to be of the highest standards, coming in on time and in budget.

New Bosch Bulldog Xtreme and Bulldog Rotary Hammer bits Bulldog Xtreme bits deliver precision and long life in reinforced concrete or harsh aggregate, while Bulldog rotary hammer bits offer speed in applications for lightweight and normal weight concrete.

Bosch Bulldog bits are the only concrete bits optimised for the next generation of rotary hammers. Bulldog Xtreme bits are built around a solid head carbide design that lasts longer in rebar than competitive offerings while providing faster drilling speed combined with precision. This performance comes with less carbide wear.

Bosch utilizes a proprietary diffusion bonding technology, a high heat, high-pressure solid state welding process, to ensure a superior steel/carbide combination. This gives Bulldog Xtreme bits superior strength and a solid carbide head that will not break off when the work gets tough in any concrete or aggregate application.

“New Bosch Bulldog bits do more than simply drill holes in all kinds of concrete,” says Bosch Accessories product manager Andrew Pompei. “They’re the only bits optimised for

the newest generation of Bosch Bulldog rotary hammers, so they optimise the user’s entire drilling system. They’re longer lasting, stronger and faster than the previous generation of bits.”

Weimar Bau invests in Sandvik BR333 breaker for difficult demolition job German demolition and civil engineering contractors Weimar Bau has been setting high standards of professionalism and workmanship for quite some time. When faced by a particularly challenging project they had no hesitation in investing in the new BR333 breaker from Sandvik Mining and Construction.

Recently, the company played a key role in the Poseidon-Haus demolition and construction project in Frankfurt am Main. The demolition work required the initial reduction of a building from 60m to 30m. Due to the confined operating area small machines needed to be used for removing the roof and ceiling. Special sensitivity had to be displayed due to environmental concerns in the area, and the need to

minimize dust and noise. Fortunately a solution to these challenges was available with Sandvik’s new BR333. This new breaker has proved ideal for Weimar Bau’s requirements due its small compact construction, being comparatively light in weight, yet able to provide an impressively high weight to power ratio.

What has made the BR333 the ideal piece of equipment for the Poseidon-Haus project is that it is specifically optimized for demolition and recycling applications, and utilises a streamlined and lightweight design that sets a new standard in low weight and high power.

As with its counterpart products, the BR111 and BR222, Sandvik’s BR333 also features: • Compact usability

Indeco sorting grabs and ISS shears serve an increasingly demanding market Over the years, the demolition market has been fragmented into a thousand different forms by operators looking to use increasingly specific equipment for each application, so as to cut job times and costs, and as a consequence make work easier and increase profitability. Their demands could not of course remain unheeded by Indeco, as its success over the years has been based on satisfying the needs of customers and prospects as quickly and as thoroughly as possible.

The new shears Indeco continued that tradition at Intermat, with the debut of the latest ISS shears, and the new IDG demolition sorting grabs.

The ISS shears were specially designed for cutting ferrous materials such as I-beams, tanks and tubing. The shears have exceptional capacity and cutting force, due to the following features: •

Four special heat-treated steel blades, which optimise long term performance. All the same size, they are reversible and interchangeable, so that all of the cutting edges can be used;

•

Deep jaw and long blades for maximum depth of cut

•

Cutting register adjustment system provides efficient working action at all times

•

Exclusive dual profile piercing tip system in both upper and lower tips, for a clean gradual cut.

The new shears also have numerous technical innovations that enhance their performance. The heavy-duty pivot group provides longterm cutting efficiency, keeps the jaws aligned, and prevents buckling. An exclusive integrated dual guide system can be used to adjust the alignment tolerance across the whole range of cutting strokes, while a large, powerful hydraulic cylinder provides enough force to deal with any type of working conditions.

Long lasting cylinder seals are able to withstand up to 700bar pressure, while the chassis is made from extra strength steel alloys, eliminating any flexing of the shear body. The ISS shears have full high-speed 360° hydraulic rotation for better positioning, and optimal cutting in any working position. The regeneration valve speeds up no load movement of the jaw, which opens and closes more quickly, thus reducing cycle times and increasing productivity.

The interchangeable quick change wear

bushing ensures that the knives are always aligned, while the large jaw opening provides greater flexibility for a variety of different applications.

New demolition sorting grabs Similarly, the new IDG demolition sorting grab is the latest milestone in Indeco’s efforts to satisfy the needs of those looking for a versatile tool that can handle light demolition work, but can also be used to select and handle the debris. Their unique structure, outstanding manoeuvrability, power, and high payload are ideal for recycling and recovery.

An innovative design and the use of special wear resistant steels have helped to create a product, which combines key characteristics, such as exceptional robustness and lightweight, with an above average payload and gripping force. Great manoeuvrability and excellent handling precision are ensured by full 360° hydraulic rotation, which makes demolition easier under any logistical conditions. The high-pressure hydraulic cylinder provides better gripping force and demolition performance.

The load jaws, which are interchangeable according to the material to be handled, are synchronised to ensure smooth movements and handling of thin materials. The wear blades are also interchangeable and reversible. Teeth can be mounted to improve efficiency and reduce maintenance costs.

Maintenance of road surfaces is a task that cannot be solved without sophisticated professional equipment.

Among various surface restoration techniques, diamond grinding and grooving and cold milling stand out as the most efficient and up-to-date solutions.

The big tracked or

Diamond grinding and diamond grooving are used for surface restoration jobs on normal roads, motorways and airport runways. Surface grinding restores ridability by levelling out any irregularities, while improving safety and reducing noise pollution. Improved safety is the result of a higher skid resistance and reduced aquaplaning. Machines that perform these tasks are big and heavy and often custom made. Only a limited number of machines are made every year and the unit price sometimes goes through the roof. But those who have made road maintenance their business know that this is money well spent.

World’s biggest grinder The German company Rellok, based in Celle is an up-andcoming manufacturer whose main expertise is in the development of floor and road saws. It has a range of hydraulic floor saws, micro trenching machines and road grinders or ‘bump

cutters’, as it calls them. Rellok has recently unveiled what it claims to be the world’s biggest grinding machine, the RSG 4600. The impressive machine was ordered by one of Germany’s most established names in the contracting business Otto AlteTeigeler. It took Rellok 3,500 design hours to develop this special grinder. Its 1.4m wide grinding shaft is belt-driven by a Deutz diesel engine. The unit has an output of 360kW transmitted to the grinding shaft. A second, 103kW, diesel engine drives the electric and hydraulic power units. The hydraulic system supplies the traction drive, steering, water supply and suction units. Both diesel engines feature an electronic control system, which monitors all functions and performance data, such as oil pressure, rotation speed, cooling water temperature or engine load. All operating and malfunction information is shown on a display. The drive and operating controls are placed on separate control panels to help the operator focus completely on the task in hand. The entire footplate is rubber-mounted to protect the operator from vibration. The RSG 4600 is equipped with two suction systems to collect slurry. Another feature is the guide wheel remote control, which controls both the side and rear wheels and height of the grinding shaft. The detachable control boxes are located at the side of the machine.

Cold milling aka Cold planing Cold milling or cold planning is the controlled removal of asphalt or concrete pavement to a desired depth. This is accomplished by bringing a rotating milling drum or mandrel into contact with the pavement at an exact depth or slope. The torn surface material is fed by conveyor into a dump truck that takes it away for recycling. The first cold milling machine was developed in 1979 by Wirtgen that to this day remains the world’s leading manufacturer in the field.

Wirtgen beefs up its heavy-duty range

50 PDi • Issue 2 • April - May 2012

Wirtgen has beefed up its line of large milling machines with compact model W220. The new machine that boasts some 80 innovative features has joined the ranks of the well established W150, W200, W210 and W250 milling units. Equipped with a 571kW engine, the W220 can reclaim up to 900t/h of asphalt under optimum conditions. The basic version of the machine comes with a 2.2m diameter milling drum. Also available is the optional interchangeable drum with a milling width of 2.5m.

The maximum milling depth for both milling drums is 350mm.

The W220 is complete with Wirtgen’s smart control system, Widrive, which not just simplifies the operator’s task, but also increases fuel efficiency. The proven cutter system allows the most diverse milling tasks to be executed, with milling drum configuration being adapted to the job at hand. The machine is automatically aligned parallel to the road surface by means of parallel to surface control, which ensures simple, accurate operation of the machine in demanding profiling jobs. PTS also assists the operator in positioning the machine in the milled cut at the beginning of the milling process. The intelligent speed control system prevents track slippage and ensures perfect traction for

D A WN THE RO all track units. A vacuum cutting system protects the operator’s environment. The system extracts fine material particles by creating negative pressure in the drum housing. The mix of air and water vapour is evacuated and then fed back into the flow of the milled material on the conveyor by a hose system.

Bobcat news at Intermat Bobcat demonstrated that it is one of the leaders in the global compact equipment market at the Intermat exhibition. The complete range of new generation compact loaders and mini-excavators was on show while at the same time celebrating 25 years in the compact excavator market. Included in the display was the new high horsepower TL470HF telescopic handler and a wide selection of attachments such as the new sonic tracer system for use with the company’s two largest 2.44m and 2.74m grader attachments.

The new high horsepower TL470HF telescopic handler is powered by the 97.5kW Perkins 1104D-E44TA diesel engine, offering higher horsepower and torque for superior performance and a maximum travel speed of 40km/h.

Thanks to the high horsepower engine, the TL470HF offers significantly increased

torque, enabling improved performance and productivity. Combined with a new load sensing pump delivering a hydraulic flow of 190l/min, the TL470HF model offers faster cycle times at a lower engine speed when performing both single and combined boom movements. This helps to reduce fuel consumption and improve efficiency.

The TL470HF telescopic handler has a maximum lift capacity of 3.5t and a maximum lift height of 7m. The capacity at full lift height is 3t, while the maximum forward reach is 4m and the lift capacity at full reach is 1.5t.

The new sonic tracer system, for use with the two largest grader attachments, emits ultra sonic signals to maintain a set distance or elevation from an object, surface or the ground. Installed on the blades of the graders, the sonic tracer allows them to be used to grade, level, and backfill on a multiple slope terrain when following a string line, kerb stone, the gutter or even a previous pass as a grade control. Grade accuracy is 6.4mm, and the detection range of the sonic tracer is from 200mm to 1300 mm.

Down to the Wire with Allied Gator’s new solution Uniquely suited to handle hardened steel wire, all types of steel cable and rebar, the patented Allied-Gator MT Series Multi-Tool fitted with the patented quick-change shear jaw set is the only shear design that has proven itself to stand up to continual use in these full-time processing applications. These materials have been notoriously troublesome for recy-

clers, and have traditionally been very costly to process with mobile shears. However, the Allied-Gator MT offers the profitable solution.

The MT’s power and rigid jaw design are just two of the key attributes that allow cutting these materials on a long-term basis to be profitable. The MT’s unrivalled throat force, generated by the patented Allied-Gator

power-link and guide system, enables the tool to power through each cut with a continual power gain, rather than lose force after these materials have massed themselves into the shear jaw.

In addition, the superior strength and rigidity of the MT’s high-alloy steel components allow the tool to shear through these

wire, cable and rebar materials while providing the shear blades the stability they require.

This enables the shear jaw set to maintain the blade clearances that are essential to continual cutting performance in these specialized applications. See the link www. alliedgator.com/videos.

New bucket crushers from Atlas Copco Atlas Copco has launched a range of four rig-mounted bucket crushers for recycling of all types of inert material on site. Asphalt, stone and concrete debris, as well as mine and quarry material, can be crushed and reused on site or sold to third parties.

Rig-mounted bucket crushers are an answer to the EU directive on waste management that demands a recycling quota of 70% for construction and demolition waste by 2020. Atlas Copco bucket crushers reduce the mechanical equipment on site, as well as transportation and dumpsite cost. They can be employed at all urban worksites, especially in confined conditions.

Hydraulic bucket crushers from Atlas Copco offer a wide aperture bucket with large capacity. The output size can be easily adjusted from 20-120 mm.

The range follows the strategy of lower cost of ownership, which is common in all hydraulic attachments from Atlas Copco.

Bucket crushers require low maintenance; a 30h greasing interval and only two grease points are the standard maintenance.

All crucial parts are long lasting even under extreme stresses. The bucket jaws, which take the most stress, follow a clever

wear part concept. They can be inverted, top and bottom jaws can be exchanged or single jaws can be rotated 180° to also use the rear part.

The bucket crusher range consists of four types of 1.5 to 4.9t service weight, which can be used on any excavator larger than 12t.

It might be a nice surprise that this year’s Intermat did exceed expectations. At least that is the general impression from exhibitors and visitors at the Paris construction show this year.

PDi’s Mikael Karlsson reports.

Due to the number of novelties displayed at the Intermat show in Paris the presentations in PDi will be divided in this issue and in issue 3-2012. Spread all over this issue you also find small notices as well as our special features on new excavators, mobile recycling equipment, hydraulic breakers, automatic quick coupling systems and road grinding and milling machines that was introduced at Intermat.

Better than expected In total, the show attracted some 1,350 exhibitors this year with 67% from overseas and an even stronger presence of manufacturers from Asia and the US than before. There were more than 200,000 visitors at the show, which was up almost 8% compared to the 184,500 at the previous Intermat in 2009. The domestic French market is also slowly picking up which was proved by the increased number of French visitors.

There were many manufacturers of equipment and machinery for demolition and recycling and also some suppliers of concrete sawing, drilling and floor grinding. Those industries also had a larger presence than before of manufacturers from Asia, especially China and South Korea.

Indeco’s Michele Vitulano told that Indeco maintain a strong position on the global market despite a troubled Italian market.

Quattro, the new shear with a revolutionary new concept launched by Genesis.

Genesis Attachments, demonstrated a new shear called Quattro, with a revolutionary new concept, according to the company. A twin cylinder configuration gives this shear a significant performance advantage over standard single cylinder models with up to 20% fuel efficiency.

The company says that the Quattro provides a higher closing force with an open shear jaw that improves cutting capacity on larger materials, such as pipes and beams. With its two smaller cylinders, faster cycle times result in improved productivity.

The configuration results in lower back pressure in the hydraulic system that lowers oil temperatures and reduces the possibility of damage to system seals. Each individual shear can be tailored to specific customer requirements.

The two cylinders are positioned at an angle to each other rather than parallel and the result is a smoother cutting force curve of the actuation cycles. According to Genesis, a single large cylinder has several disadvantages, such as slower cycle times resulting in lower productivity, a relatively high back pressure that results in higher oil temperatures and the risk of seal damage.

The leading manufacturer and supplier of surface processing and cleaning machines, Blastrac, introduced the new BMG–780RS, a triple head grinder designed for finishing large horizontal surfaces.

Caterpillar’s new M318D MH Material Handler

CX470C Offers Increased Performance And Economy Case Construction Equipment is introducing the CX470C, a Tier 4 Interim crawler excavator offering a 6% increase in lift capacity, greater digging efficiency, reduced emissions and up to 5% lower fuel consumption. The machine features a larger operator’s cab, with lower noise levels and improved safety. Advanced hydraulic control systems contribute to increased efficiency and lower fuel use. Replacing the CX470B, the CX470C uses a 9.8litre Tier 4 Interim certified diesel engine with cooled exhaust gas recirculation. Maximum power of 270kW is delivered to the operator by Case intelligent hydraulic system technology. This includes boom economy control to automatically reduce engine speed and hydraulic power to the boom when speed and power are not a priority. Swing relief control manages the hydraulic power supplied at the start of the swing operation, while spool stroke control automatically adjusts the hydraulic pressures to meet the demands of digging operations.

An auto economy control automatically lowers engine speed when the joysticks are inactive, lowering fuel consumption. Fuel delivery is also computer controlled, which combined with variable geometry turbo charging allows the engine performance and speed to be automatically matched to hydraulic system and power requirements. The machine also delivers up to 5% faster cycle times. The ROPS/FOPS Case C Series cab, with external protective cage, has 7% more internal space and 25% more airflow from the

air-conditioning system. Internal noise levels have been reduced to 73dB(A).

The CX470C has a high definition 178mm LED monitor in the cab, providing all necessary system information. This monitor also provides a full colour screen for the standard rear view and optional side view camera feeds.

The CX470C is available with a long undercarriage or a retractable undercarriage. Both undercarriages can also be specified on standard or mass excavation specification models. Operating weights range from 47.7t to 49.2t. The LC machines are offered with a choice of heavy-duty dipper sticks, at 2.5m and 3.4m. The CX470C ME uses the smaller 2.5m dipper as standard, with a shorter 6.55m monoboom. Lift capacity on the LC chassis is increased to 10.5t, while the ME undercarriage machines offer an increase to 9.89t.

As with all C Series excavators, there is a range of buckets and attachments available for the CX470C. These include pin-on buckets, coupler buckets, the Case multi-fit coupler and the smartfit bucket tooth system. Pin-on buckets are available in heavy duty, heavy-duty high capacity, severe duty and rock digging designs.

Case excavators benefit from 1,000h greasing intervals on all pins except the bucket, while 500 hour engine oil change and 5,000 hour hydraulic oil change intervals provides maximum operating time.

The new Cat M318D MH Waste Handler is a wheeled excavator designed for use in work areas with limited space. This new configuration incorporates undercarriage and boom modifications, while retaining the proven features of its conventional M318D MH counterpart.

The M318D MH Waste Handler features a purpose-built undercarriage that preserves the rugged strength of the conventional M318D MH undercarriage, but adapts the structure to the machine’s specialised application. The heavy-duty swing bearing tower is now centred on the undercarriage, placing it equidistant from axles and stabilisers for symmetry and optimum balance, whether working over the front or rear.

In addition, the tower is larger to accommodate the hydraulic cab riser swing bearing.

The boom for the M318D MH Waste Handler also has been significantly modified to fit the machine to its tasks. The new boom has a shorter pin-to-pin length of 5.35m, compared with the conventional M318D MH’s dimension of 6.4m. This compact material handling boom, designed for use with the 4.2m stick, features a welded, box-section design with thick, multi-plate fabrications in high stress areas for superior durability.

As with all Cat Wheeled Material Handlers,

the M318D MH Waste Handler can be equipped with a quick coupler and a range of specialised work tools.

Growing interest fo The Swedish hydrodemolition manufacture Aquajet Systems believes that potential users of the concrete repair technique are growing. Aquajet has managed to widen the application spectrum for traditional hydrodemolition contractors but also opened the eyes to new categories of users. One example of this was the Open Day at their factory in May.

During the 1970s, when the first hydrodemolition systems were launched, the number of applications where the method was used was limited to bridge and car parking decks, power plants and quay walls. Now the situation is different and one of the manufacturers that has broadened its field of application is Aquajet, based in the small Swedish community of Holsbybrunn.

Strong Progress Aquajet Systems sales manager Jan-Åke Pettersson says that as the technology has developed, more and more categories of contractors in construction have started to show interest in the hydrodemolition technique. “A lot has happened with our products over the past five years in particular. Above all we can say that we have refined the concept and broadened the flexibility of our product range. The fact that we use high-pressure water in our demolition method is currently not as big a problem as before with the older systems,” says Jan-Åke Pettersson.

Removal of damaged concrete with high-pressure water jetting is extremely effective and it is also only the damaged concrete that is removed. The undamaged concrete will remain and form a perfect surface for adBelow from the left: Stefan Hilmersson, Ronnie Hilmersson and Jan-Åke Pettersson from Aquajet Systems AB.

The principle of the basic products used has not changed much since the 1970s. It is still mainly robots, guide rails and framesystems and rotors that are used. But the technology is completely different and refined today. Capacity has been considerable increased and the systems are far more flexible. They can now be used in more applications and in particular in extremely cramped and confined spaces. The new hydrodemolition systems can be adapted to a much greater degree than before.

Aquajet Systems is the prime example of how this technology has taken several steps forward in recent years. Hydrodemolition robots are more sophisticated, as portrayed in the new robot series Aquajet 710.

The robot has been completely redesigned. The internal

parts are easily accessible and above all the capacity and flexibility has been improved. It is easy to operate, easy to program and maintain. Another major innovation in Aquajet Systems’ hydrodemolition method is the new Evolution II with a new control system and new EDS smart lance control. The system allows hydrodemolition in a new unlimited way. The operator can precisely control the shape and depth of the surface to be removed. With these new benefits hydrodemolition techniques can be increasingly used in applications where previously inefficient methods were used. Aquajet Systems has also increased the accessibility dramatically with new types of boom systems and tower solutions on the robots, as well as new types of frames and guide rails systems.

“There is almost no place where our equipment cannot reach and carry out a perfect job. The client just let us know what they need and we build the system for them. It can either be a specially tailor made solution or a modification of our

standard machines,” says Aquajet Systems CEO Stefan Hilmersson.

A recent addition is the new Aqua Spine system, which easily reaches in under and behind for example bridge parapet or a dockside.

“Frankly, today only the operators own imagination makes the limits,” says Hilmersson.

Traditional customers days in Sweden The news from Aquajet Systems over the past two years

or Hydrodemolition has been endless. Each year the manufacturer organises special client days at the plant in Holsbybrunn. Here they show and demonstrate their latest products. This year the Open Day was held on 3 and 4 of May. About 50 customers attended from many countries, including Austria, Germany, Poland, France, Russia, Sweden, Norway, Denmark, Scotland, Australia, China and others. The day began with a joint collection and review of the product range and its news. Two students at the Royal Technical High school Stockholm, Fernand Ndayizeye and Maxamed Abdiraxman, presented a research project on the resistance of the concrete repaired with hydrodemolition methods. Tests have so far shown very good results and the research project will serve as a recommendation to the construction industry for use of hydrodemolition for the renovation of damaged concrete structures.

The two day meeting started with a presentation of Aquajet’s robots models with different boom and tower settings, followed by product demonstrations in the test area. These included the new 710-series with the EDS Smart lance powered with the new and Aqua Cutter Powerpack 700. Damaged concrete to any shape to almost any depth can be removed with Aquajet equipment.

From the left to the right: Aquajet Systems agent in the UK, Alistair Mackenzie from Aquapower Ltd., Finlay Crocker CEO and Ewan Crocker Operation Director from the Scottish concrete cutter firm Corecut Ltd. and Aquajet Systems Jan-Åke Pettersson.

Growth of user categories Increasing numbers of contractors are showing interesting in using the hydrodemolition technique. An example is Scottish concrete cutting and demolition contractor Corecut Ltd. “We currently work a lot with special applications in areas, such as the nuclear power industry and we believe that hydrodemolition equipment could very well fit as a complement in the services we provide today.

We also often come across traditional hydrodemolition tasks on the concrete cutting and demolition project we work with today,” says Corecut CEO Finlay Crocker.

Also in other countries in Europe demolition and concrete cutting contractors are looking in to the possibilities that the hydrodemolition technique can offer, as long as the supply of water is not a problem. In its development Aquajet is aiming to minimise the amount of water needed for the hydrodemolition technique. The robots and frames are also being developed so that the high-pressure water is concentrated in the correct area.

There are also special solutions for containing the water.

The first of the Aquajet Open Days ended with a presentation of the new Aquajet SmartPhone Application by chief designer Ronnie Hilmersson. “Being the world leading inventor of hydrodemolition equipment and accessories we have developed a powerful tool for everyone using high-pressure water for efficient concrete renovation with hydrodemolition, ultra high-pressure or

“Recycler manufactu It seems that the demolition debris market has been quite severely affected by the financial situation in the world. PDi’s Heikki Harri has been taking a look at what’s up with the recycler manufacturers.

The economic problems are prevalent mostly in the industrialised regions because most demolition takes place there and consequently, manufacturers tend to continue with their existing products and machines rather than inventing new equipment and solutions. At Intermat, very few manufacturers of tracked recycling crushing plants showed anything new, but brought to Intermat machinery that had already been shown to the public last year. However, the number of exhibitors of recycling crushing plants was as large as always in recent years. The market is still lucrative and all parties concerned are aware of a positive change is around the corner, but nobody knows how far away the corner is.

In the meantime it seems that many smaller manufacturers are concentrating their efforts on building up sales networks in regions where they have not yet been active. Naturally, improvements in the design, fuel consumption and technical details are being made all the time.

Nakayama Iron Works Nakayama Iron Works is a Japanese company with a tradition of over a hundred years since it was established in 1908. The company is focused on crushing and screening and some other activities related to construction, quarrying and more recently demolition. Nakayama is also currently an active international player exporting machinery to nearly 70 countries.

Nakayama equipment is extensively being used for asphalt and concrete crushing, demolition and rock crushing. One of the latest models is the NC420CE equipped with a jaw crusher that makes it suitable for asphalt, concrete and rock crushing. The machine’s power source can be either a diesel generator or commercial electrical power supply. The latter case means that the machine operates without emissions and is clean to the environment.

Nakayama’s concept in tracked mobile plants is based on quick set-up, easy maintenance and compact dimensions to allow using the machines to be used in narrow urban sites.

Keestrack’s green The Belgian manufacturer, Keestrack, has introduced a new line that they describe as ‘The green electric alterna-

available as three or four split classifiers, are now available in the ECO-drive version. The electrically driven machine can run autonomously by the diesel engine, which generates the electric power, but the electricity can also be supplied by the electricity network or from an electrical plug on the crusher.

The screening results are the same as in standard versions, but due to the opportunities to use electricity the maintenance cost of the ECO-drive diesel engine is much lower. The concept saves energy and costs, and reduces emissions.

Astec – KPI-JCI The American manufacturer Astec and its wholly owned company KPI-JCI have entered the tracked recycling machine business with the objective of becoming one of the big manufacturers in this special application line.

In particular, the company has concentrated on tracked units equipped with impact crushers.

The impactor product line includes five models that are suitable for aggregate production, as well as recycling.

KPI-JCI machines feature Andreas Series HIS crushers.

The weight of the smallest plant is 37t and that of the biggest one 51t. The production capacities vary between 295t/h and 680t/h. All models are complete with a screen

Focus on fuel consumption As for the fuel consumption, Metso claims to have designed models with lower consumption. Metso did not participate at Intermat in Paris, but instead launched a re-designed version of the LT106 jaw plant at the Mawev exhibition in Austria at the end of March. One of the new models has already been working in Norway and the customer reports 20% to 30% lower fuel consumption.

“Today the fuel economy is becoming more crucial in contract crushing and naturally in all crushing operations. In the design of the new LT106, special attention was paid to the overall fuel economy. The favourable results in this respect were achieved due to the economical Tier4/Tier3 engine module, improved hydraulic system and new hardware design,” says Metso product manager Jouni Hulttinen. The international launch of the new LT106 takes place at the Hillhead quarry exhibition in June in the UK. PDi reports below on the most recent new machines and applications in this segment with a focus on companies and machines that are or might be new to some readers.

Metso has redesigned the LT106 jaw plant from bottom to top and decreased the fuel consumption considerably.

customise the production according to customer needs.

In the jaw line there are three models with weights from 37t to 56t. They offer capacities from 295t/h to 610t/h. The jaw plants also can be applied in aggregate crushing and recycling of demolition debris and other materials. They are equipped with the company’s Vanguard Plus jaw crushers.

There also are eight models of standard tracked screening plants and two models of high frequency screening, which feature aggressive vibration applied directly to the screen, allowing the highest capacity in the market for removal of fine material, as well as chip sizing.

Kleemann screens Last year Kleemann, the German Wirtgen Group’s manufacturer of crushing and screening plants, introduced their new EVO series. (See PDi 2011 issue 5). But Kleemann also manufacturers a large series of screening plants.

“From the technological point of view screening plants are not as exciting as crushing plants, but nevertheless, they play a very big role in the preparation of mineral raw materials, which is a valid reason for us to have a large selection of screening plants in our manufacturing programme,” says Kleemann head of sales Markus Wörner. “We have, 12 models in our Mobiscreen series with screening areas from 3.4m2 up to 18.4m2. We say that there is a matching mobile screen for every mobile crushing plant in our product range.”

In the screens Kleemann makes a similar distinction as with the company’s mobile crushers. The line is divided in two categories of contractor line and quarry line. The contractor line is the one aimed at recycling, among other applications. The capacities of the screening plants extend from 200t/h up to 500t/h. The smaller models are equipped with two-deck screens and the larger ones either with two or three decks.

local Mawev show in March to launch their newest development that is geared around a new drive concept called Innodrive.

According to the company, economic efficiency is the important factor in the Innodrive concept that includes such features as direct power transmission, simple handling, no wear parts, weight reduction, smart design, and absolute maintenance free.

In addition to the Innodrive concept the company has developed the mobile plants in many aspects. For instance, the units are equipped with a main conveyor that can be lowered hydraulically and a foldable motor housing, which offers optimum maintainability. According to the company spokesman, the recycling and related requirements have changed in a couple of years and the demand is more and more for compact, powerful and high output machines, which is what the company wants to offer.

Innocrush offers quite a few additional features

as part of standard delivery. They include a magnetic separator, dust depression, remote control, side discharge conveyor, and a service engineer for training after delivery.

Terex Finlay One of the new pieces of machinery in Paris was presented

by Terex Finlay in the form of a heavy duty screening unit bearing the model number 863. The machine is versatile, since the manufacturer says that it can be used in quarrying, mining, construction and demolition for screening debris, topsoil, recycled materials, sand, gravel, coal and crushed rock and stone. It is a two-deck screener with both decks having an area of 2.755m by 1.2m. The screen box angle can be adjusted hydraulically between 14° and 18°.

The 863 is equipped with three hydraulically folding discharge conveyors allowing for maximum stockpiling capacity. The standard hopper capacity is 5m3.

Innocrush crushing units can be applied in quarrying and recycling.

Julie White and Alan Rogers of D-Drill

D-Drill’s investment in its staff has been recognised by a major award The UK diamond drilling and sawing company D-Drill, which has offices across the UK and an HQ just outside Coventry, won the Coventry Telegraph’s Training and People Development award at a ceremony at the Ricoh Arena. “I am delighted to pick up this award. Despite

the recession and downturn in construction, we have continued to invest heavily in our staff, ” said Managing director Julie White said.

“That has allowed us to grow the business and awards such as this are recognition of that. The business was started here in Coventry and Warwickshire so it is fantastic to be recognised in our local area.

We are also proud that our training and development practices are being hailed across all industries not just in construction.”

Julie has shown great faith in apprentices and apprenticeships, so much so that she is even going through the scheme herself to ensure that she understands what her next generation of employees are going through. D-Drill currently has 12 apprentices on its books and more than 45% of the current workforce have come through the scheme or are currently undertaking an apprenticeship. But it’s not just the apprenticeship scheme that highlights the company’s commitment to the training and development of its workforce. Julie has overseen a 12% increase in spend per head on training throughout the company in the past year. Each D-Drill branch trains a quarter of the workforce in special operations, while short-hit sessions are being employed throughout the year. It is all having a dramatic, positive effect on the overall business as customer satisfaction has risen, accidents have been significantly reduced and D-Drill’s market share has increased. On top of that, the company has just received a platinum award in CSCS certification, the only diamond drilling company to attain that status.

DF Ecology Fights Dust in Chile DF Ecology, the Italian producer of dust suppression equipment, water recycling systems and wheel-washers, responded to an appeal by a mining company in Chile, Carmen de Andacollo, for a purpose designed Dustfighter dust suppression unit. The Dustfighter

produces a fine mist of water through a series of high-pressure jets, which is propelled onto the site by a powerful fan, covering a wide area.

Carmen de Andacollo had been impressed with the general

performance of the Dustfighter product, but needed some additional components to meet with their specific requirements. The request was transmitted via DF Ecology’s official Chilean dealer, Dust Control S.A. based in the capital, Santiago.

Working closely with Dust Control, DF Ecology designed the Dustfighter Super Tank, which incorporates an extra large water tank and hydraulic elevating platform that helps to direct the Dustfighter’s fine water spray. The large water tank ensures continuous operation.

Power is provided from an integral, super-silenced, diesel generator and the unit was mounted onto an eight-wheeled tow trailer.

In order to reduce air pollution, the South American mining industry controls hazardous material using a variety of dust suppression methods, especially on very big open cast mines. These types of mines generate a high volume of dust when loading earth, rocks and minerals on haulers and during the crushing of rocks and boulders. In these situations the DF Ecology range of dust suppressors are ideally suited for inhibiting the dust pollution caused by earthmovers and crushing equipment.

In 2010 the Dustfighter won an award from the European Rental Association and described by the judges as a ‘fantastic niche product and an environmentally important one.’ DF Ecology also distributes products manufactured by TowerLight based in Villanova d’Ardenghi near Milan.

UK’s NFDC host world’s first high reach training course The UK’s National Federation of Demolition Contractors and its training arm the National Demolition Training Group have jointly hosted a dedicated training course on the safe use of high reach demolition specification excavators. Thought to be the first course of its kind anywhere in the world, the new course builds upon the operating principles detailed in the Federation’s recently published High Reach Guidance Notes and sets a new standard in the operation of these highly specialised machines.

Three days of training The course was developed in conjunction with training specialist Duncan Ruddal and is designed to provide experienced excavator operators with a firm foundation in the operation of high reach machines with a working height of up to 30m. Held over a three-day period, the first two at the NDTG’s Hemel Hempstead headquarters and the third at Komatsu UK’s manufacturing plant near Newcastle, the course covered the entire key basic operating practices included in the NFDC’s High Reach Guidance. Course content included machine design, machine guarding, visibility, stability and ground pressure, drop and exclusion zones, start-up and shut-down procedures, and machine maintenance. Particular attention was paid to structural awareness, site suitability, and ground conditions.

“Thankfully, the UK has an exceptional safety record with the use of high reach demolition excavators. But the incidents that have occurred have generally been the result of failing to identify underground voids when tracking a machine across a site or operating the machine wrongly for the type of building,” says NFDC chief executive officer Howard Button. “To avoid these problems in the future, a large part of the new course content has been developed to ensure that operators are fully aware of their surroundings and the specific challenges presented by each new site.”

Positive comments from the Professionals The inaugural course was attended by experienced operators from some of the UK’s leading demolition companies, and the course content was well received by all of them. “The course was very informative,” says AR Demolition’s Tom Poole.

“All the trainers involved have a great first-hand knowledge of the business.” Poole’s comments are echoed by those of Paul Best from Erith Contractors who said: “The NDTG trainers have done it all before and they clearly know what they’re talking about. The course provides a great foundation.”

NDTG training group manager Sophie Francis, who attended the first course herself, says that the delivery of the world’s first dedicated high reach excavator training course was a real team effort. “The course was written by Duncan Ruddal with input from Howard Button.

The practical part of the course was held at Komatsu UK’s Birtley factory. And the cost of each trainee’s participation was covered by a grant from CITB-ConstructionSkills,” says Francis. “Without their input and enthusiasm, this course could not have taken place and the NFDC and NDTG owe all of them a huge debt of gratitude.”

German Demolition Conference in 2013

On 15th and 16th March 2013 the German Demolition Association will stage the 19th edition of the Demolition and Dismantling Conference in Berlin. With about 75 exhibitors and 640 registered participants in 2012, it is currently Europe’s biggest event in the field of demolition.

Because of the past two years greatly increased demand from both the participants and exhibitors, the DA has decided to give this Europe’s largest trade event a new frame. As a new venue, the Hotel InterContinental was chosen. The DA expects to meet more subscribers as well as the individual needs of the exhibitors.

As in this year, the DA will offer simultaneous translation of German-English/English-German in 2013. This will ensure that the event will gain more attraction for an international audience.

Take the Demolition Conference as a warm up to next year’s Bauma in Munich to get first impressions on current issues and the market situation in the demolition industry. No other conference in Europe provides the opportunity to meet so many experts and decision makers about demolition.
