A complete new development of impact mechanism minimizes the discharge of vibration to the excavator, as well reduces the operators vibration stress drastically. In relation with this new developed breaker body, the fully closed frame with rubber plugged service points and a new worldwide patented rod arrangement, gives a considerable reduction in noise levels of 7db. Because of FRD optimized the applied materials with a new hardness process, a higher efficiency at same operation weight is guaranteed.

“One step forward and two steps back” Dear Colleagues Summer has finally arrived after another difficult winter that caused additional problems for an already suffering construction economy in many markets. But in Europe the picture is quite mixed. Some countries are doing very well, some are picking up while a few others have reach the bottom, but not yet seen signs of recovery. But still and overall it is a little bit like “one step forward and two steps back”. The Iberian Peninsula is a good example of this situation. But in this case we are not talking about any steps forward yet. But Spain is believed to have reached the bottom, even though some say that the real estate prices need to go down a bit further for Spain really to start to turn. Spanish manufacturers are struggling to find new ways of making money. And they are good at it, good at adapting and creating new product concepts that are very beneficial to their customers. A very good example is the Andalusia based company Sima in Granada, which I visited in March this year. There is more information about Sima on pages 64-66 in this issue. This issue of PDi is full of news for demolition and recycling contractors. There are two interesting special features, one about new hydraulic breakers and another on new mobile recycling equipment. We are also publishing details of new and interesting high reach demolition excavators. This spring has been very hectic and interesting with many changes and events. In Europe we have seen a clear recovery in many markets and others show signs of picking up, such as the UK. The situation is perhaps not completely satisfactory, but it is going in the right direction. Also in the US the recent ConExpo event showed a clear optimism in the US market. PDi was at ConExpo as well as the Samoter show in Verona and the German concrete sawing and drilling show BeBoSa. In this issue we are publishing reports from all of these shows. We also attended the IACDS annual meeting, which was held in Bruges and the European Demolition Association’s convention in London. These were two very interesting events, providing a lot of news and details of these meetings will be featured in detail in the next issue of PDi. At the IACDS meeting in Bruges Jose Blanco from Spain was elected new President of IACDS. I would like to take the opportunity to welcome this young, vibrant and very efficient man to head the IACDS. I also thank the past IACDS President Peter White for his great work during the two periods he was the President. Peter has an enormous experience of the industry with more then 50 years working with concrete sawing and drilling and he has also a fresh and inspiring wind for this industry. I can promise you will see more of Peter in this magazine. At the IACDS meeting it was also decided that next year’s IACDS meeting will be held in conjunction with the CSDA meeting in Hawaii. For those who would like to join tickets need to be reserved to get to the island of Maui. I would also like to inform you that PDi has employed an additional editor in Petra Linderoth. Petra will mainly work with our rental magazine, but also support the editorial work on PDi. See 16 for more details. And last I would like to wish you all a wonderful summer with a good mix of work and relaxation; something we all need.

Words from the new IACDS President
“From White to Blanco”
It is just a coincidence, but up to this meeting of IACDS the president of the International Associations of Concrete Drillers and Sawers was Peter White, and it is now my turn, Jose Blanco, to lead this wonderful group of professionals. The funny part is that in Spanish White means Blanco, as the English translation for Blanco is White. Allow me to have my very first words on this column to acknowledge the work of Peter White, not just as President of IACDS for the past two years, but mainly for the work done on his company (D-Drill) as a sawing and drilling specialist, and also as President of the UK Sawing and Drilling association. Peter is a true man of this industry. One day he decided to become an employer, instead of being an employee working for the electricity business; he started his own company on a new field: cutting concrete with diamond tools. Peter did well and despite the difficulties on the construction industry (where is never easy to work as a specialist contractor) he managed to get on. Today his daughter, Julie, runs the company D-Drill and Peter takes care of other business (helping out with the national association, playing golf,…). Well done Peter. You deserve to be on IACDS “hall of fame”, together with other well-known professionals of this industry: Otto Alte-Teigeler, Horst Wapler, Kaspar Disch,… and many others. If you look at the picture illustrating this column you may find Peter letting go his duty as President, and telling the new guys to take good care of it. From left to right, you may find Norikazu Shibuya, IACDS Vice president, myself, Jose Blanco, now assuming the role of IACDS president, Peter White, IACDS past president, and Lars Sandstrom, IACDS Vice president.When Jan Hermansson (editor of PDi) asked me for a picture for this first column, I really wanted to emphasize that IACDS is both international and team oriented. It is also interesting to note that Peter is the only contractor on the picture. Mr. Shibuya runs a manufacturer company in Japan, well known for their machines for the sawing and drilling industry. Mr. Sandstrom runs the Swedish
Sawing and Drilling association, as general manager. And myself, Jose Blanco, I work with enterprise associations related with the construction industry. It is as general manager of the Spanish Sawing and Drilling association, AEDT, that I was called to become the new president of IACDS. AEDT is a very young association, created on 2006. It became a reality thanks to the support of the IACDS. Just so you know, the Presidency of IACDS changes every two years, and before Spain, it was held by the United Kingdom, and two years before by the United States of America. But the Spanish Association is not the newest member; this honor goes to SNED-SCBD, the French Association of the Demolition Industry (Syndicat National des Entreprises de Démolition). In this very unique case this association (SNED) represents together the demolition companies (manual, mechanical, explosives,…), the diamond experts (sawing and drilling) and the asbestos removal specialists. SNED became a member of IACDS on our last meeting in Brugge, Belgium. Our meeting was held in May 7th with a very good attendance from different continents (Asia, Europe and Americas). On top of our market reports, networking and other activities, we had two guest speakers to talk about grooving: Philip Zuzelo, from Cardinal Grooving (USA), and John Willis, from Tyrolit UK. Thanks to their presentations we had the chance to get into more details of this specific technique, grooving, used on airports, highways and other surfaces, for better friction and noise reduction. Next year, 2012, we will have our annual convention with the CSDA, the Concrete Sawing and Drilling Association (USA), celebrating their 40th anniversary. And the meeting will be in: Hawaii!! Ok, let’s face it! Hawaii is a bit far for most of us. But think about it: international convention, concrete cutting, and Hawaii. Are you going to miss it?
Best regards Jose Blanco President IACDS

Words from the past IACDS President
“Thank You Friends!” We had our International Association of Concrete Drillers and Sawers annual general meeting on 7 May, 2011 in Bruges, Belgium and on the Friday we were all welcomed by Mrs H Decleer a city councillor of Bruges at the city hall in their 800 year old council chamber and then treated to a tour of city hall. We were given an overwhelming welcome to the city. At the meeting there were 14 countries represented from all around the world. We also welcomed new members from France Mr M. Hiblot and Mr F. David representing SCDS/ SNED. There were some important subjects discussed besides minutes of last meeting accounts for the year and budgets for next year namely additions to the world tolerances for drilling and sawing with the hard work being put in by the association in Germany, Austria, Switzerland and the Netherlands with the draft to be finalised by 13 May, 2011. We also done a market update on countries around the world which can be obtained from the IACDS website. www.iacds.org. We did have reports from the European Demolition Association and from Federation of European Producers of Abrasives for more co-operations between the three Associations, which can only improve relationships between the various industries. Mr A Kossolapov from Russia is going to create a concrete drilling and sawing expressions directory i.e. a list of various words or sayings in our industry translated into other languages. He has also done a paper on promotion of concrete drilling and sawing for planners and for the training of people in universities and colleges. This is budgeted to go ahead in the next couple of years. He is also going to produce a book about all aspect of drilling and sawing which is in Russian at the moment and to be translated in English for worldwide distribution in conjunction with the IACDS. New activities include getting employees to be aware of international exchange scheme. Also raised was the argument about standardization of connecting tools and whether IACDS should support manufactures or contractors. We had two excellent speakers one being Mr Phillip Zuzelo of Cardinal Grooving of the USA on importance grooving on runways
8
at airports which helps grip on landing which stops aqua planning which is compulsory in the US but not the rest of the world and a new grooving method; Utilization of trapezoidal shaped grooves. Further information contact him at www.cardinalgrooving.com. Our other speaker was Mr John Willis of Tyrolit UK on a new method of diamond grinding of concrete roads to increase their life span. Contact him at www.tyrolit.com. IACDS diamond awards congratulations to the three winners Gold Award Tondin S.r.l Italy Silver award Thayr S.L Spain Bronze award D-Drill England. The next awards will be presented at Bauma 2013 so contractors need to get their entries ready for submission by October 2012 for contracts completed from now to October2012. The IACDS intends to hold a seminar in the similar lines as we did in the 2010 at Bauma 2013 topics to be finalised nearer the date. I as the outgoing president would like to thank the following people Anna and Daniel Trachsel for their hard work as secretary and of running the international association, and the two speakers for the excellent talk and last of all the delegates and international members who attended. It was a shame that our Honorary President Mr Otto Alte-Telgler could not attend due unforeseen health reasons. Last thing I would like to say is welcome to the new president Mr Jose Blanco and I hope he has a good presidency as I have had.

Brokk delivers robots to Fukushima in Japan Brokk is delivering robots to Fukushima nuclear plant in Japan. The first task for the machines is to provide access to highly contaminated areas and clean up contamination. “One key difference between Brokk’s demolition robots and other robots currently on site is that our machines are capable of carrying out multiple different and tougher tasks, such as tearing down concrete structures and take care of heavier contaminated materials” says Brokk CEO Martin Krupicka. The first contact with Brokk and its Japanese partner BGE Company Ltd was taken soon after the accident at Fukushima, as Brokk demolition robots are known globally for decommissioning and material handling in radioactive environments. Brokk has since then had staff in place in Japan to better understand the situation and the challenges in detail. The first Brokk machine, delivered in middle of April, will be used to get inside one of the most damaged reactors. The last month has been a very intense time for Brokk’s staff and its subcontractors in order to be able to deliver the machines in a very short period of time. With the ongoing crisis at Fukushima, every day saved has been of high value. Brokk staff is currently present in Japan to provide training on the machines and their capabilities to the local operators. Brokk has successfully delivered robots for demolition, decommissioning and disposal of radioactive material to the nuclear industry for over twenty years, including to the USA, France, Great Britain, Russia and Japan. Brokk machines have for example been used for decommissioning and cleanup at Chernobyl in Ukraine. “Brokk was chosen for this extremely challenging work by Taisei Corp, which works for TEPCO at Fukushima, because of our extensive experience in the nuclear industry. Today we have over two hundred
machines at various nuclear sites worldwide”, says Mike Evans, Head of Nuclear at Brokk. Brokk has proven and tested products and solutions after having delivered more than 5,000 demolition robots worldwide for the past 30 years. The Brokk machines can also be equipped with a variety of tools, making them the real multipurpose machines. A second shipment of three Brokk machines took place using a specially chartered flight from Luleå Airport in northern Sweden. These machines were all designed and modified to handle the extreme situation and the high radiation at the Fukushima site. Among other things, the machines will be operated from a control room located as far as one kilometre fom the reactors. Currently, the machines are expected to be working onsite at Fukushima within the next few weeks.

This facility will be used for new equipment demonstrations and for practical modules as part of a number of training courses. A decorative floor surface was required for equipment display purposes and the company opted for Resdev’s Pumazzo TZ epoxy terrazzo in mid grey. The concrete subfloor was shot blasted using an SPE9ES Autoblast Machine, primed and material applied in a two day period. The terrazzo was then finished using the DFG700 planetary grinding system working through metal graded diamond tools to a 100grit resin tool. Edgework was also prepared and finished using SPE’s range of hand tools and diamond products. The area was then grouted, reground with 100grit tools and then sealed with Pumadur DD Gloss Clear. The main walkways were again prepared using dust free shot blasting, primed and Resdev’s Pumadur RT Polyurethane system applied. The combination of steel, concrete and screeded practical demonstration pads, together with a stunning decorative display and viewing areas, have provided the company with a state of art facility for use by visitors from around the world.

Wacker Neuson opens used equipment centre The official opening ceremony for the Wacker Neuson used equipment centre in Gotha was hosted on 6-7 April 2011. “We got off to a great start,” says Head of Wacker Neuson Used RalphJörg Gruber. “Our first-ever equipment auction proved a particular hit with visitors.” Fritz Huber, a leading name in the industrial auctioneering business, held the auction. Prospective buyers had the opportunity of viewing the items for auction online before the event. A wide range of machines went under the hammer, including internal vibrators, pumps, rammers, plates and compact equipment weighing up to 15 tons. With its central location and excellent highway connections, the Wacker Neuson used equipment centre is easy to reach. Spanning
16,000 m2, it provides an ideal platform for the sale of used light and compact equipment. The centre also offers used competitor models from comparable segments. The centre’s website, is the hub of its sales concept and all products can be viewed online at www.used.wackerneuson. com.
EDA Words from the EDA President
“Three valuble days in London” Recently, the European Demolition Association (EDA) celebrated its annual Spring Conference. This time, the event was held in London, being always a very interesting venue for its perfect communications and other facilities but specially now as the city is getting ready for the 2012 Olympic Games. During these three days, we were able to attend to a very professional and complete program, which we hope was interesting for our associates and also the whole industry, as we think it has. As President of the association, I would like to thank all the people who have helped EDA, in one way or another, to make this Conference succeed. Of course, much of the responsibility for the quality of the event falls on the speakers, whom we would like to thank very much. Mr. Howard Button, NFDC General Manager, shared very detailed information about how NFDC is preparing the High Reach training. Just after Mr. Button, we could listen to Mr. Steve Jack, MAGNOX D&D Programme Manager, who gave us some interesting clues about an interesting market with lots of possibilities: Power Station Demolition. Mr. Iñigo Vegas came from Spain to speak about the IRCOW Project, related to Innovative Strategies for High-grade material recovery C&D and waste. Ms. Katherine Adams, BRE Principal Consultant, shared some experiences on waste management, focusing on the actual situation and what shall it be in the future. Mr. Steve Bleninsop, Pre-construction Manager at ERITH, showed a urban demolition project in a crowded area, downtown London. Coming from France, Mr. Daniel Rieber gave a presentation about the updated Ferrari demolition technique, using jacking, showing us the process and including very illustrative examples with photos and videos. Mr. David Sinclair, EDA Past President, associated with SAFEDEM Limited and also Member of NFDC spoke about the history of EDA, how the association was created and how these years of history are also a path to success of many entrepreneurs. It was a very interesting speech for many of the young faces attending the EDA conference. Specially invited to this event, directly from the USA, we had the opportunity to hear Mr. Tom Stahr, ROBINETTE Emergency Response Division Manager, sharing insight on how to carry out a Crisis Strategy for our companies. Mr. Tom Stahr shared also interesting possibilities for demolition companies working on Emergency Response, based on the experience of the company Robinette Demolition Inc. (founded and managed by Thomas A. Robinette). After a very interesting history, EDA keeps moving forward, and this year with the change of Secretariat, we wanted to
12
know first-hand the opinion and expectations of EDA members for the future. For this reason, we run questionnaires about the present and future of the association, to collect the feedback of the members and I am sure they will give us lots of good ideas. There was also time to make new contacts and meet acquaintances from the demolition industry in an easier way, through the diverse leisure activities offered this year, being one of the nicer opportunities the Gala Dinner, which venue was really remarkable (London Royal Courts of Justice). During the dinner, we announced the Club of Honor and introduced its members, who delighted each guest with their words and presence. This initiative is born to recognize the activity of certain people who have been and are very important for both EDA and the entire demolition sector. EDA would like to recognize them, for their service to the demolition industry: Mr. H. van Eck, Mr. David Sinclair, Mr. Gerard van Vliet, Mr. Walter Werner, Mr. Serge Perdrieu, Mr. Howard Button, Mr. Jan Brandis, Mr. Yves Canessa, Mr. Celso Anka, Mr. Domenico Ferrari, Mr. Dietrich Korth, Mr. Daniel Midavaine and Mr. Philippe Sellier. All of these gentlemen are a great source of know-how for the new demolition generations. It is remarkable for me to observe how generational change is taking place all over our industry and especially in the National Associations in Europe, and I was very pleased to see lots of new and younger faces all through the audience, eager to learn and work in this industry. The Club of Honor will be open to receive more members in the future, as we have to recognize the work and ability of professionals that dedicate their life to the demolition business. Last, but not least, I would like to thank all of our associates, National Associations and International Committee, for all their help and support during this Conference but also through the whole year.

Julie set for Mount Everest base camp A female construction leader is set to prove she is made of the White stuff later this year. Julie White, who runs the UK concrete diamond drilling and sawing specialists D-Drill (Master Drillers) Ltd in Coventry, will be taking on the 11-day walk to Mount Everest Base Camp in Nepal. The base camp is at an altitude of 5.5 km and will provide the managing director of D-Drill with one of her greatest ever challenges. Julie White agreed to take on the challenge after sponsoring explorer Mark Wood in his bid to be the first person to walk to the South Pole and North Pole back-to-back. “If anyone buys and takes on and runs a business in the construction sector in the largest recession the UK has ever seen, they clearly enjoy a challenge. But this walk is going to be a really tough physical and mental challenge but one that I am really looking forward to,” says Julie White.

Young Swiss cutting specialists visit Hilti in Liechtenstein
PDi • Issue 2 • May - June 2011
Switzerland is one of the countries where the job of cutting concrete is an official and authorised profession. The apprenticeship takes three years; the young people learn their job in their diamond service contracting company on job sites, the practical training in the training centre of the Swiss association SVBS (www.svbs.ch) and the theoretical education at the professional school BWZ (www.bwzofingen.ch). Recently the apprentices of class BT08, who will finish their apprenticeship in June, visited the Hilti headquarters in Schaan, Liechtenstein. The visitation was exclusively for the diamond products. The youngsters got a lot of information about the Hilti diamond business, the production of diamond core bits, wall saw blades and assembly lines for core drills and wall saws and how their working tools are produced.

Great expectations To meet the exacting demands of the world’s demolition contractors, breaker manufacturers are packing their products with power and performance. PDi’s Jim Parsons reports.
In spring it’s said a young man’s thoughts turn to love. In the demolition industry, spring is when men and women of all ages turn their thoughts to the equipment necessary to vie for project opportunities that, hopefully, are coming their way. Because breakers large and small are usually the centrepieces of most contractors’ equipment arsenals, manufacturers continually look for ways to tweak their lines through enhanced features or entirely new products. But unlike romantic relationships that can be fleeting or fraught with drama, the choice of a breaker is all business; its ability to help the contractor get things done better, more efficiently, and at less cost than
before. So you will forgive demolition contractors if they seem to have a little extra difficulty making up their minds this spring, as manufacturers have given prospective purchasers a lot to think about. For example, Hydraram’s new 13-model FX line of hydraulic breakers range from 100 to 6,100 kg, and are suitable for excavators from 1 to 80 t. The FX series’ optimized hydraulic/N² driven system delivers high impact energy with less vibration and sound thanks to a special dampening system. The models have only three moving parts, piston, valve and chisel, in a fully protected box-style hammer body.

Yanmar-Socomec collaboration produces new breaker models Yanmar has teamed up with Socomec to produce a new nine model DMS range of hydraulic breakers to complement its mini-excavator range from 700 kg to 9.5 t. The new DMS breakers are built in a monoblock structure, eliminating traditional tie rod bolts that often break. The only part that needs to be assembled to the body of the breaker by screws is the accumulator, which doubles as a cap to seal the top of the breaker. By simply removing the accumulator, all bushings and the piston are
immediately accessible. In its silenced version, the mono-block structure of the DMS series is vulcanized in a unique body with the external case by means of a patented polyurethane solution. Noise is reduced to a minimum and the miniexcavator’s arm is protected from micro vibrations. The unique stepped piston design delivers maximum energy to the chisel and minimum recoil to the breaker body. The DMS breakers have an advanced modular hydraulic brake on the piston to prevent the hammer from harmful blank firing. When the tool is not in contact with the rock, the oil supply

is automatically recycled and pressure strokes are avoided. A flow diverter valve is placed inside the mono-block to stabilize the working pressure regardless of the oil flow, resulting in a constant energy stroke.

Stanley’s MBO5 is three breakers in one Stanley Hydraulic Tools’ new lightweight MB05 concrete breaker features a single four-position bracket that spins into position, allowing skid steer loaders to operate from multiple angles without interruptions for back plate changes when breaking down walls or sidewalks. The proprietary bracket expands skid steer work areas and sight lines with angles ranging from 18 to 36° downward, settings that normally require use of separate back plates for each position. By combining three bracket assemblies into one component, MB05 brings major increases to skid steer productivity and substantial reductions in operating costs and dealer inventories. A side-plated model easily attaches to miniexcavators with two pins or through a bolt-on quick coupling process. “MB05’s three-piece, modular construction is the least complex, easiest, and most cost-effective to maintain, and among

Designed to meet the needs of the users of excavators in the 45 to 65 t range, the 4t, 3m high MDO 4000 TS shows off all the technical advantages that Socomec has become known. An innovative system allows users to easily tailor the frequency and
Chicago Pneumatic has added 13 new models to its new RX line of hydraulic breakers, each designed to work with a specific range of carrier. For example, the 746-joule RX-4 is designed for 2 to 6t carriers, while the 1,017 joule model is tailored for skid steers. Models RX14 and up feature a Power Stop function that reduces blank firing, protecting the breaker and carrier and increasing the working life of the components. The larger models in the RX line, RX25-RX53, feature a power control valve to increase productivity. This enables the operator to set the breaker characteristics according to the application for higher productivity. The RX25-RX53 models also feature a fastening system that uses head bolts and insert threads to distribute the thread strain equally. Designed with fewer components and fewer moving parts, RX line breakers are easier to maintain and repair, a critical consideration for contractors who want to reduce the risk of job-site downtime. All RX breakers also include a power boost feature that achieves higher breaking performance in tougher applications without requiring additional hydraulic input.
the most powerful in its segment,” says Stanley Hydraulic Tools president Martin Schnurr. “It’s a one-size-fits-all tool that eliminates the need for extra skid steer brackets and side plates in dealer inventory stocks.” With an operating weight of 367.4 kg, and one of the lightest in its class and 20% lighter than the MB356 breaker it replaces, the MB05 brings increased stability to 3t skid steers and 3.6t miniexcavators. Flow rates range from 38 to 83l/m, powered through direct acting nitrogen, delivering 1,550b/m, almost 50% more than MB356 and well above most comparable models. The MB05 comes with exclusive features that reduce service time and operating costs, including bushings that last longer than their conventional counterparts. Worn portions of upper bushings rotate 90° to the side, and lower bushings are flipped four times before replacement. A sleeve around the piston allows quick and low-cost replacement of parts damaged by contaminated oil.
power of the hammer’s blows to the resistance of the material it is working on. This makes the operator’s job easier and ensures optimal results from one job to another. Because tie rods in conventional hammer structures require frequent maintenance, Socomec development a new system that allows tie rods on the MDO 4000 TS to be tightened without threading, resulting in more elasticity and durability.

areas. An improved cooling system, the heart of the user-friendly design, uses an air deflector to transfer cool air to the percussion system. This decreases the BH 65’s overall temperature and increases the operator comfort, safety and service life of the breaker. Improved ergonomic features include a new compact design with redesigned hood and handles that make it easier to operate the unit. Along with the unit’s patented air percussion system and vibration dampening housing, this feature enables operators to work for longer periods of time under more comfortable conditions without compromising performance and increasing productivity. To improve handling and maintenance, a repositioned fuel cap is easier to access from any position. This allows the operator to refill the tank with the unit upright or lying on the ground. An integrated purge bulb removes air from the fuel line and improves starting. Another

Atlas Copco’s heavy hydraulic breaker models, HB 2000 HB 3100, and HB 4700, are designed to allow smaller attachments and carriers to provide the same kind of performance as their larger counterparts. All three deliver significantly more power than their predecessor models. The breakers are equipped with the PowerAdapt system, which shuts down the breaker in case the oil pressure is too high. “This is useful when the hydraulic breaker is used on different carrier units,” says Atlas Copco medium and heavy breaker product manager Torsten Treger. “Hydraulic breakers can generally be hydraulically overloaded if the carrier’s oil pressure has the wrong setting. In order to ensure that our customers can make full use of the equipment in terms of efficiency and power, we have equipped the entire range of heavy-duty hydraulic breakers with PowerAdapt.” With an improper carrier oil pressure setting, conventional pressure relief valves, as the ones frequently used in hydraulic breakers, continu-

ously drain oil into the tank and therefore waste precious energy. This affects the efficiency and profitability of the equipment. The improved guide system of the hydraulic breakers provides a better stability and resistance. “After all hydraulic breakers are subject to tough operating conditions,” says Treger. “A new retaining bar provides better protection especially in the lower part of the hydraulic breaker, which has to take a lot of wear and tear. Both the Dust and Non-Dust versions of the three new models are furnished with the same all-round wear protection.” The HB Series also feature the VibroSilenced System to protect operators against noise and vibrations, AutoControl to adapt the blow frequency and impact energy to the rock hardness, and the ContiLube ™ II integrated automatic lubrication system. The StartSelect feature allows the operator to influence the breaker’s starting and shutdown behaviour, while an optional DustProtector prevents penetration of lower parts by dust and rock particles.
Okada has designed its TOP 280 breaker for a wider range of applications than the company’s previous 20t class model. Matched with an 18 to 30t class carrier machine, the TOP 280’s hydraulic circuit breaker provides a 12% higher
impact frequency with similar blow impact power. In addition, new component materials and a new chisel set pin fixing system extends the life of the chisel by 35%. The TOP 280 also does not require an accumulator, and is easily maintained with only a few spare parts.
new product entry from Wacker Neuson is the EH 75/240, the only 240V electric breaker available in the United States. Using any construction grade 3.8kW portable generator, the EH 75/240, with an integrated inverter, converts single phase to three-phase power ensuring that each time the tool hits the concrete it delivers a consistent hard blow. Because of the inverter, the EH 75 can be powered by a brushless three-phase motor and offers consistent power supply even when using a long extension cord. The inverter also protects the tool with an automatic shut off if input voltage is too low or too high, providing for long life and unmatched durability. By eliminating the traditional rotor and carbon brushes found on competitive models, Wacker Neuson has eliminated the need for maintenance on this tool. With no brushes to replace or winding failures to contend with contractors can be assured that this tool will provide the best uptime in the industry.
The EH 75 weighs only 26 kilo, and hits with 75 joules. With the high percussion rate of 1275 blows/min, the EH 75 offers the highest power-to-weight ratio of any breaker in this size class. Because the EH 75 and a small portable generator can easily fit in the back of a pickup truck, the new tool can meet the performance of 27 to 32kg pneumatic hammers, while eliminating the need to tow a compressor. The EH 75’s outstanding performance and extremely high breaking output is the result of a new hollow piston percussion system with a rod striker and patented shockwaveoptimized percussion system along with the high single stroke energy.

pushing for increased performance and production output in rock excavation and demolition,” says Grado Cero representative Dick van der Starre “At the same time clients are asking for lower maintenance costs, less down time, and better warranty conditions.” The Xcentric Ripper features patented impact vibration accumulation technology that makes it more productive than most of the other hydraulic breakers or hammers now available. Grado Cero has found production increases of two to
five times in 60% of the job applications where it has been used. In addition, the Xcentric Ripper’s closed energy chamber is fully protected from dust, water, and dirt, providing trouble free performance under the most severe conditions. This includes tunnels, foundations, and under water in harbours, canals and open sea. “This is why the Xcentric Ripper significantly reduces the maintenance and repair costs that normally appear in such working circumstances,” says van der Starre.

Launched at Bauma 2010, Demarec’s new Dedicated Demolition Line has proven to be just what the market was asking for. The DDL’s 25, 30, 45, and 60 class models are designed to work with excavators ranging from 18 to 65t. The all-rotatable DDL, consisting of pulverisers, as well as combi shears and demolition shears, work well with hydraulic quick-change systems that involve coupling and decoupling of the hose connection. This includes systems such as Oil-Quick, Likufix, Vario-Lock and Riedelberger. All wear parts allow for quick and easy onsite exchange and are interchangeable with other Demarec products, like the static pulverisers and Multi-Quick Processors. The DLL-Line can be equipped with the DemaPower-System, which provides 20% more power and a double working speed valve for extremely short cycle times, as well with a two chamber cylinder technique that also includes a speed valve.
FRD XS breakers make for a quieter workplace Europe’s demolition contractors can look forward to quieter job sites with an FRD’s FX 15FX55 breakers, designed for 1 to 6t excavators. Built around a standard frame for topbracket mounting, the breakers feature an extreme silent low sound power option that not only minimizes the discharge of impact vibration to the excavator, but also drastically reduces the operator’s vibration stress. In relation with this new developed breaker body, the fully closed frame with rubber plugged service points and a new worldwide-patented rod arrangement considerably reduces noise levels of 7db towards the standard frames. Because FRD optimized the applied materials with a new hardness process, a higher efficiency at same operation weight was guaranteed.

Small breakers, big performance Not all the breaking news on breakers involves large, hydraulic attachments. Those in the market for smaller, hand-operated models will find a great variety of models and power sources. For example, Hilti has unveiled its TE 3000AVR electro-pneumatic breaker for heavy breaking applications and demolition work at floor level. The TE 3000-AVR boasts the power of an air tool, at the same weight level, without the need for an air compressor to deliver explosive breaking power and exceptional mobility. And with Hilti’s sub-chassis active vibration reduction system, the tool reduces fatigue and allows operators to work longer. Weighing approximately 30kg, the TE 3000AVR delivers 68 joules of impact energy to break up to 5.4t/h of material, a rate comparable with a similarly sized air tool. Because it does not require an air compressor, the TE 3000-AVR allows contractors to have their tool set up and working before the compressor is even towed to the location and hooked up. For maximum versatility, the TE 3000-AVR accepts standard chisels, same as air-powered tools. The TE 3000-AVR is also durable, thanks to an active cooling system that reduces wear and tear on the motor, electronics and hammering mechanism. A brushless SR motor eliminates the need to replace carbon brushes, allowing longer intervals between service and twice the expected motor life.

NPK GH Series offers world-class power NPK’s new GH Series hydraulic hammers may be lighter in weight, but that does not keep them from delivering high impact energy. In fact, the GH Series may well be the most powerful hydraulic hammers in the world. Models range from the GH-06 with an impact energy rated at 203 joules, to the giant GH-50 with a rating of 27116 joules. The GH series feature a unique nitrogen gas-charged piston action that delivers more
power with less recoil, yet with only two moving parts in the main valve. The result is a constant energy/blow and high breakout force, rather than being dependent on the blow rate. Despite its power, the GH Series is all about minimizing vibrations that can accelerate wear. The hammer enclosure utilizes a unique new range of brackets, while models from the GH-7 up feature heavy-duty shock-absorbing rubber
cushions to absorb shock, recoil, and impulse vibration. The cushions also protect the integrity of the excavator and boom, reduces wear, and increases operator comfort. Other features include replaceable bushings that prevent wear to the main chisel holder body and enhances breaker life, and automated lubrication channelling to support installation of a lubrication system.
and weld, which makes the rebuilding process easier and lowers life cycle costs. Both Caterpillar’s D and E series feature automatic shutoff, which turns the hammer off when no material is present beneath it. The system prevents blank firing of the piston and
increases hammer reliability and durability by eliminating the high internal stresses created by blank firing. Operating pressure can be adjusted externally for easy service when necessary, while standard sound suppression improves operator comfort and environmental protection.

Also it features constant blow energy regardless of the oil flow adjustment within the specifications. No periodical gas recharging is required for
the H25D, whilst servicing or resealing. The replacement of the single lower tool busing can be done in a matter of minutes enhancing minimal down time and better productivity. The hammer comes with a complete mounting group for the HEXMN 300.9D machine. The single bushing can be replaced in 10 minutes.

combination of one single and one twin blade arm enables maximum stability even under extreme loads. Universal arms and Steel cutting arms versions are available for the CC 4700. The crusher arms are stably mounted on a central main pin, reducing the time required for changing crusher arms by up to 75%, compared to separate mountings. Both crusher arms can be fitted and removed as a unit, because the coupling and positioning system, continues to link the two together even after removal. Crusher arms can be changed on site, thereby avoiding time-consuming and costly transport to the workshop. And the practical concept for wearing parts also saves time. Crusher teeth and cutting blades can be turned or changed quickly and easily on site. “We found that about two-thirds of the operating cost of an

In 2010, hydraulic equipment expert EuroramRockmaster BV was approached by Hencon Mobile Equipment BV, which at the time was working on the development of a crust breaker, and needed a supplier of a hydraulic breaker suitable to the specific needs of their project. As a worldwide supplier of custom made mobile equipment for the heavy industries, Hencon BV specialises in the development of solutions for situations where conventional vehicles cannot operate satisfactory. For this particular project the crust breaker, used for breaking slag on liquid aluminium, was to be fitted with a hydraulic hammer that can perform under extreme circumstances. Based on the technical requirements supplied, Euroram Rockmaster BV set to work on the modification of its Globram RM45 breaker. Changes were made to its hydraulic and mechanical properties to guarantee optimum performance in this specific, tough application. With both companies satisfied with the outcome of the project, several more modified breakers have been delivered over the past six months. Following this first successful project, the two Dutch companies are continuing their cooperation in new projects. Both are confident the cooperation will expand into the future, and will allow both Hencon Mobile Equipment and Euroram Rockmaster to maximise their flexibility and improve their respective product ranges.

VTN’s new FB 150 Crusher Bucket
Dr. Schulze launches new dry coring system at BeBoSa Dr. Schulze GmbH used BeBoSa to unveil a new system designed for dry coring in heavily reinforced concretes. The new system consists of a rugged drill stand, electric drill motor and drill bits DCD-SP developed specifically for dry drilling. On customers’ requests, the system may come with an industrial vacuum cleaner and other accessories. The system is designed for 28-130mm drilling to a maximum depth of up to 500mm. To achieve the maximum drilling depth, a 260mm long bit can be extended by using a 300mm extension shaft. The new set-up is said to revolutionize concrete coring because it allows for drilling in a very dense and heavily reinforced material at a speed, which is equal to that of the wet process. But unlike wet drilling, the machine generates virtually no slurry and dust. Another
great benefit of the new system is that it does not require any additional cooling which makes it the perfect choice for jobs at nuclear power plants or newly-remodeled premises. The system is also well suited for overhead applications. The crucial part of the rugged stand is a column with the steel tooth rake, which is designed to withstand high drilling loads. The roller guides ensure smooth and precision operation. The electric motor is equipped with a two-speed reducer and an input for vacuum cleaner. One of the motor’s key functions is automatic shutdown at overload that helps prevent damage to the core bit. The core bit is installed on the motor’s spindle by a trapezoidal thread that protects the bit from dust and ensures its quick assembly or dismantling. The custom-made modular drill bits DCDSP remain the most important element of the
ALLU’s new products at ConExpo
ALLU Finland managing director Kauko Pylväs. The demonstrations ran all day and every day of the exhibition and received a lot of positive feedback. Material used in the demonstrations was very harsh and made many visitors return to watch again how ALLU screened the huge rocks from the gravel. ConExpo visitors were also first to see the new ALLU PMX Power Mixer, officially launched at ConExpo. The new mixer is a part of the ALLU Mass Stabilisation System meant for stabilising soft or contaminated soils and processing dredged sludge. The new PMX mixer has many new innovations, including inclined drums that minimize the dead area of the bottom frame. This ensures easy penetration through hard crust soil layers.
At ConExpo the Finnish company ALLU presented its D–series in a series of demonstrations for visitors. These were the ALLU DNS 3-12 fine screening attachment, ALLU DH 4-17 for screening and crushing with changeable blades and ALLU DNS 2-09 fine screening attachment mounted on a small skid steer loader. At the ALLU stand there was a large number of visitors to the demonstrations and a positive feeling of better times ahead. “The exhibition was a huge success and there is an obvious change towards better times in sight. In some countries the movement is faster and in some the start is a little bit slower, but the direction is right,” says

entire set-up. Due to their modular construction, the core can be easily removed from inside the bit by screwing off one of the two modules. The changeable module can be used repeatedly and save the cost of buying new core bits. During multiple tests on different job sites, the system has shown very high drilling performances even on extremely reinforced concrete. It is true that tools for dry drilling and sawing put a bigger strain on the user’s budget than regular diamond consumables. But it s also true that on sites where the use of water is off-limits, such as nuclear power plants, server rooms and new offices, dry coring is the only viable option. And even where water is allowed, the time-consuming process of water connection and collection eats up the savings of purchasing cheaper tools. http://goo.gl/6K5bK http://goo.gl/kSgXv
Following the encouraging response at the Bauma preview, VTN Europe recently completed its new series of Crusher Buckets by introducing the FB 150 model at Samoter in March. The new FB series is not the result of a simple restyling of the previous range, first introduced in 2004, but the result of the company’s commitment to produce equipment that increasingly distinguishes itself for its quality and reliability. By taking into account both the experience gained over time and tests conducted following feedback from our users, VTN’s technical department focused on a new job with the aim of creating models that have been improved in terms of structure, as well as performance, comfort and safety. The new version of VTN’s Crusher Bucket is more attractive thanks to its more uniform design. The jaws are again made with precasting techniques and retain their reversibility and can be used at least twice as long before replacement. To make it easier to adjust the mobile jaw, VTN has introduced direct access from outside, making it easier to extract or insert the special linings, which in turn determine the range of movement. FB 150 completes VTN Europe’s range and can be used on excavators between 10 and 16t. The mouth measures 600 mm in width and 450 mm in height and has a capacity of approximately 0.5m3.

Conexpo showed true signs of optimism
ConExpo-Con/Agg 2011 turned out to be a very pleasant surprise for most exhibitors and visitors. Even though the economic situation in the US is far from back on track, the Las Vegas based exhibition showed clear signs of optimism and that the American people and the market has decided to take a clear action forward.
More the 2,400 companies exhibited their products on an area that measured 217,400 m2, an exhibition space that was the second largest in the show’s history. More then 117,000 visitors came to the show and the overall reaction among visitors and exhibitors was overwhelming positive. The international registration accounted for a record 24% of the total visitors, representing more then 150 countries. And despite continued uncertainty in the US construction markets and the overall economy, industry professionals were optimistic for a sustained US upturn in the coming months, while global sales continue to be strong.
A light in the end of the tunnel “The construction equipment industry is pretty resilient and we felt that we have made it. At this point there is a light at the end of the tunnel, and it is not a train,” says chairman of the 2011 ConExpo-Con/Agg management committee and president of Gradall Industries Mike Haberman. “It was important that the US government passed a transportation bill as soon as possible as infrastructure projects create jobs and with that the economy. Visitors say they have been at the show to
examine the latest equipment and product technologies and innovations to help them prepare for future business and exhibitors cite the high quality of customers and report strong purchases and sales leads to new as well as existing customers.” Megan Tanel, vice president of AEM (Association of Equipment Manufacturers) agrees fully and said: “The US construction industry has been through some very tough times with record unemployment since the last ConExpo-Con/Agg in March 2008. With these positive numbers and the industry support of the show, we’re optimistic about the future and looking forward of seeing these new sales orders fulfilled.”
Strong international presence In terms of demolition and recycling equipment there was a very strong presence of manufacturers from countries outside the US. There were many Italian manufacturers this time and several of the Italian demolition manufacturers were exhibiting together with their US distributors or through their own US corporations. The company VTN Europe introduced their new cooperation with US distributor Rotobec and showed a new series Issue 2 • May - June 2011 •

of demolition and recycling attachments developed for the US market. Quite a big number of new demolition attachments were launched at the show and several of them feature in this issue of PDi. There was also quite a gathering of mobile crushing and recycling manufacturers. Several new recycling units were launched and are covered in our special recycling feature on pages 56-63. Atlas Copco took the chance to introduce their new Powercrusher range on the US market. And Rockster Recycler launched new machinery. It was also a clear trend that compact and mobile recycling units are becoming more popular on the US market, which also has been taken up by domestic producers.
Tons of news There was also a big number of new compact loading equipment on display with many new models suitable for loading demolition debris on narrow indoor renovation and demolition projects as well as outdoor heavy demolition projects. There were very few special demolition rigs on show for heavy duty and high reach demolition. The large demolition machines with long

In terms of remotely controlled demolition robots, three manufacturers were represented. These were Brokk, Finmac and a new machine from Hong Kong based HD Engineering. Brokk showed their two latest additions the Brokk 260 and Brokk 400. Finmac showed their existing model F16 in the Stanley La Bounty booth. The Finmac robot is, besides Stanley LaBounty, marketed by the US company Wrench. The company offers a wide and comprehensive range of equipment for demolition, including two dust cannon brands from Italy. Another US company that has increased its marketing efforts across the US boarders is Brunner & Lay. The company has a long and strong reputation of developing and manufacturing chisels for hydraulic breakers. The new demolition robot model from HD Engineering, HD-50 RB, is quite an interesting piece of equipment developed for heavy-duty remotely controlled demolition. The unit weighs about 5 t and has a reach of approximately 8 m. HD Engineering was once a distributor in the Far East Asia for Brokk. There were also plenty of models for demolition contractors that would like to do something radical about preventing dust from spreading on outdoor demolition sites. A big number of manufacturers of dust cannons showed their latest models. Several of them are based in Italy but still the biggest in this area is US Dustboss, which introduced several years ago the revolutionary method of using water mist to bind dust particles in the air.
were present as well as manufacturers of concrete floor grinding and polishing. These manufacturers mainly choose the World of Concrete to show their equipment. The 2011 edition of ConExpo-Con/Agg offered a fresh start of something very positive on the US market, clear signs of a turn in the economy. Let us hope that the show turned out to be a boost for the economy that will help the US construction market to recover.

Updates for Komatsu Dash 8 Demolition Excavators
Komatsu offers a complete range of Dash 8 Demolition Excavators specifically configured for demolition work, with options designed to meet the rigours of tough demolition applications. The high reach equipment is complemented by conventional demolition excavators, available with mono, straight or two piece boom options that can carry out site clearance and other essential tasks on demolition sites. 36
New JCB’s for demolition At the forefront of its demolition offering is JCB’s range of purpose-built tracked excavators. JCB offers XD (Extra-Duty) versions of its JS220 and JS260 excavators, which feature alongside the successful high reach demolition rig for the JS330XD model. Each features strengthened boom and dippers, rugged undercarriage guarding and covers, side rail protection systems and FOPS cab guards with a host of further options. At the smaller end of the spectrum, Micro excavators are also invaluable for stripping out recyclable materials such as gypsum, plasterboard, and Artex. Small enough to fit through a standard doorway, the JCB Micro can deliver powerful performance within a building. A 13.7kW (18.4hp) engine can handle the toughest tasks in the tightest environments, whilst the undercarriage extends from 700 mm to 1000 mm giving excellent stability and lift capacity. Fitted with a bucket or breaker, the JCB 8014, 8016 and 8018 mini excavators are perfect for bringing down internal walls or for general clean up and loading out work
The PC290LC/NLC-8 is the latest addition to the high reach demolition range and was first presented at Bauma 2010. Following the European Demolition Associations safe working range guidelines, it is ideally suited for demolition of two to five story buildings or buildings up to 15m height without the need for a platform.
Extra protection Its size is advantageous, particularly in restricted areas; the relatively light weight of this machine makes it easily transportable. It can work in areas where larger 60-70 tonnes machines with normal boom configurations cannot. Recently Komatsu also added extra protection features to all the Dash 8 demolition excavators. These latest developments include: •
An opening front guard: Already proven on High Reach Demolition, it is now available on all Komatsu demolition excavators. Operators can easily clean the whole window space regularly for maximum visibility.
•
An optional cylinder guard: Top and side protection of the cylinder rod ensures maximum protection against damage from falling debris. (Standard on HRD machines)
•
A reinforced side link: Demolition work is tough and continuous use of heavy attachments can induce higher stresses than conventional digging work.
•
A boom lamp guard : Extra protection from debris
•
Completing the range, Komatsu’s short tail excavators with a level II Operator Protective Guard (OPG) are ideal for those special demolition jobs where work space is limited.

Movers and shakers:
Rusch unlimited PDi’s new series Movers and Shakers feature dedicated to the demolition industry’s trendsetters rolls on. The current episode features Rusch, the Dutch manufacturer creating exotic demolition giants that look as if they came straight from a sci-fi movie.
A cross between a demolition excavator and a crane, Rusch machines are capable of bringing a building down from as high as 90 m. The sky is definitely the limit when Rusch set itself a new challenge.
High-reach man Rusch’s owner and managing director, Ruud Schreijer, is a human equivalent of the machines he devises. Extremely tall and powerfully built, Ruud is very imposing. He had acquired a vast experience in the crane industry by working first for Zandaam-based Kenz Kraantechniek, then for the British Kenz Cranes Ltd for almost ten years. In 1991, he ventured out with his own company called Rusch. Given Ruud’s extensive background in cranes, it is a small wonder that repairing telescopic booms for mobile cranes became Rusch’s core business. It is believed there are only three companies in the world that provide that kind of service, and Rusch is proud to be one of them. A few years later, the company added offshore crane inspection, testing and certifying of lifting and fire-fighting equipment to its scope of activities.
Taking on demolition In 2003 when the Dutch economy plunged into recession, Rusch found itself in dire straits. With 40 people on the staff and no work, it became painfully obvious that the company needed to find a project with a longer lead-time compared to Rusch’s usual range of services. An opportunity presented itself in 2005 when the Dutch contractor Beelen approached Pon Equipment, the Caterpillar dealer in the Netherlands and a long-time partner of Rusch, with a tall order of building a 60 m demolition rig. Beelen also wanted the machine to be CE certified. A joint team of Rusch and Pon Equipment engineers worked on this project for almost a year to deliver Europe’s highest demolition installation in 2006. The TUHD 60 (Telescopic Ultra High Demolition) was based on a Cat 385 excavator modified by Rusch to accommodate a specially designed 60m boom carrying a 2.5t demolition tool. The TUHD 60 was Rusch’s first foray into the demolition sector, and the company learned a lot from the experience. The next demolition project, which took place in 2007, saw Rusch
build its first triple-boom machine. With the boom designed to move 33m up and 20m down, the triple-boom 33-15 was equally suited for high-reach and harbour applications such as demolition of shipwrecks.
Reaching for the sky But the real breakthrough came one year later when Rusch made headlines with the world’s highest demolition crane TUHD 90-5. This 90m monster was ordered by a Dutch demolition contractor for ultra high-reach demolition jobs. Nobody had ever attempted anything this big before, but Rusch always thrived on challenges. A 130t Cat 5110 B excavator, which was chosen as the rig carrier, underwent so many modifications that it was hardly recognizable. Its body was made longer and wider, and its tracks lengthened by 2.5m. The base machine carried a 90m telescopic boom with a 5t tool controlled by an enhanced electro-hydraulic system developed in-house by Rusch. When fully assembled, the TUHD 90-5 makes a jaw-dropping sight. By building it, Rusch has proved once again that the ability to create something truly extraordinary can only be limited by a creator’s imagination and self-imposed restrictions.
The Big Wolf project In 2009, Norway-based AF Decom won a contract to demolish nine offshore platforms from the North Sea. The project called for the platforms to be brought onshore one by one by a barge, where AF Decom was to dismantle them before the next barge came in. It was obvious to the contractor that cutting the platforms to transportable pieces with shears would be the fastest option. But the problem was that the cutting had to be done at a height of 50m, with the structures to be cut being 915mm diameter steel pipes. The only suitable tool for a job like this might be a 25t shear. All those constraints meant that a very special machine was to be used on the project, so AF Decom went on the Internet looking for a possible supplier. The moment they came across a TUHD 90-5 video, they knew that they had to look no further. Soon after the initial contact was made, Rusch delivered its first proposal in accordance with the job specification. AF Decom, however, felt that the estimated budget might be an issue and asked Rusch to come up with an alternative. This is how the Triple 34-25 model, designed for 34m high-reach demolition work, was created. The new design won the approval of AF Decom, and Rusch was ordered to deliver the machine within 10 months. Rusch opted to use a Caterpillar 5130B as the Triple 34-25 base and a Genesis GPX 2500R shears for steel cutting. The force that the GPX 2500R shears generated proved to be a major challenge on this project. When the tool was not optimally positioned relative to the object, the powerful reaction force went through both the object and the boom. The reaction force was, in fact, so big that, theoretically, it could move the entire machine. Rusch solved this problem by developing the revolutionary EXPREV system (EXceptional force PREVenting system) that absorbed the excessive forces created by the shears. The system was not the only innovation born out of the cooperation between AF Decom and Rusch. AF
Decom requested the Dutch manufacturer to come up with a solution to protect the boom cylinders, and Rusch duly obliged. The solution they found was a thick rubber pad over the cylinders. Since operational safety is of paramount importance on high-reach jobs, the Triple 34-25 was equipped with a computer-assisted safety system similar to that used in the TUHD 90-5. The system constantly tracks down the boom reach to avoid the danger of capsizing. The angle sensors record the exact positions of the elements and send a signal to the central processing unit. The unit calculates the centres of gravity and outputs this data on to the touch screen installed in the cabin. When 90% of the maximum reach is achieved, the pre-alarm indicator lights up. At 100% of the permissible reach, the control unit receives a signal to shut down the hydraulics and immobilizes the machine. AF Decom was delighted with the machine performances, and the job was successfully completed. Since the Big Wolf project, the Triple 34-25 has proved its worth many times and is still in high demand for offshore platform demolition jobs.
RS4500 series If Rusch had only built the TUHD 90-5, it would have been enough to secure the company a prominent place in the history of controlled demolition. But even with four demolition crane projects under its belt, the manufacturer refuses to rest on its laurels. The new project, the RS4500 series, is now underway at Rusch. This series is based on an 85t excavator and designed to operate with either a telescopic or knuckle boom. One of the RS4500’s features is versatility. The machine is suitable for a broad range of applications, including Rusch’s trademark high-reach jobs as well as digging and foundation ripping. The new series is expected to be released in the autumn.

lver Lining! Although Hitachi Construction Machinery Group has a long track record of building machines for demolition applications, its European subsidiary diversified into this business about six years ago. The construction industry was booming at the time, and OEM machines of high quality were in keen demand in Europe. Then the world began to slip into recession, with building projects getting mothballed almost everywhere. But every cloud has a silver lining and in Hitachi’s case, the silver lining turned out to be brighter than anyone might have expected. Mark contends that this particular crisis was actually positive for the demolition sector because it sent a wake-up call to dealers. When demand for general construction machinery plummeted, dealers were forced to find alternative options to prop up their dwindling revenues. Once they realized the real value and profit-making potential behind demolition, sales of specialized demolition equipment began to climb back up all over Europe.
decided to forge ahead and further extend the wheeled line.
The future shines bright With 1,400 demolition machines built since 2002, Hitachi Construction Machinery has firmly established itself as one of the world’s leading OEM manufacturers. Its European daughter company has done an equally good job in promoting the Hitachi brand on the continent. With an extensive 40 plus dealer network, a parts distribution centre in Oosterhout and a factory and training centre in Amsterdam, HCME is well positioned to provide its customers with OEM machines and spare parts in an efficient and quick manner. The recession loosens its grip now, and Hitachi is determined to use the impending upswing to turn a mere silver lining into a solid-gold advantage over the competition.

Different customer mentality Hitachi designs and builds its demolition excavators in Japan. It means by default they are extremely productive and reliable. But it also means that they are very task-specific. It reflects the key difference in the Japanese and European approaches to demolition. In Japan, it is a common practice to use a few demolition machines, each unit for every task, on the same site. European contractors, on the other hand, always demand versatility from their machines. They want an excavator that would be able to perform the entire range of demolition and material-handling jobs on its own. This has to be taken into consideration by every manufacturer that wants to be competitive in Europe. Therefore, Hitachi’s Japanese and European operations are now finalizing together a new design concept for demolition excavators for the European market.
Ultra high-reach is not a priority When asked about ultra high-reach applications over 40m, Mark said that making machines for these tasks would not be part of Hitachi’s strategy. A demolition contractor may purchase a standard Hitachi excavator and have it modified for super high-reach jobs. Hitachi’s ZX-3 series, for instance, is particularly popular with the manufacturers that create special demolition one-offs, and a good number of exotic machines have been devised on this basis. However, there will be no serial production of ultra high-reach machines any time soon. The company is rather more interested in developing a market for small demolition excavators ranging between 8.5 and 25t. According to Mark, this segment has huge potential and definitely is one of Hitachi’s priorities now.
Mark Burghoorn is the demolition product manager at Hitachi Construction Machinery (Europe) NV.
Good year for wheels Material handling has always been and will remain paramount for Hitachi. The European subsidiary began to supply factory-modified machines for material handling some two and half years ago. The current line-up includes six models with four crawler and two wheeled versions. Mark says it is the wheeled end of the range that attracts most interest from the customers. The 2011 order portfolios for the 28t ZX250W-3 and 36.5t ZX250W-3 wheeled excavators are already full to the brim. Fuelled by their success, Hitachi has Issue 2 • May - June 2011 •

Liebherr and the macaronis The Liebherr R 954 has a range of 34 m, it is fully demolition equipped, which includes a tilting and extra protected cab, hydraulically adjustable chassis and hydraulically removable counterweight.
Lotus Machinery & Transport AB is currently conducting a spectacular demolition of a macaroni factory on Kvarnholmen in Nacka just south of Stockholm. Waterfront apartments, with stunning views over the water and Djurgarden, will be built on the site. For the demolition Lotus is using a new demolition equipped Liebherr R 954, the first Liebherr demolition machine in Sweden. Lotus Machinery & Transport AB is a growing demolition player in Sweden. The company was founded in 1996 primarily as a transportation company. But over the years Lotus has gradually expanded its operations into excavation and traditional land and construction contracts. In recent years it has also begun to offer demolition services. Demolition activities have increased heavily, especially during the last two years, which has resulted in investment in new demolition orientated equipment.

herr, the first of its kind in the Swedish market.
Significant investments in demolition services Lotus has annual sales of SEK70 million and 70 employees, with about 25 working purely with demolition. “Demolition assignments have grown progressively in recent years and prospects for continued growth look very good,” says Anton Segerlund, who runs Lotus Machinery & Transport AB with his father, mother and two brothers. “We have had good order entry throughout
the recent recession and we have almost a full order book going forward. The job situation has called for us to review our machinery park and our new Liebherr R 954 fits in very well with our expansion plans.” It was Anton’s father Seppo Suomila who started Lotus Machinery & Transport AB. Lotus is purely a family business and mother Margaret and Anton’s brothers Peter and John also work in the company. The emphasis on demolition operations is on complete demolition of all kinds structures in the building and process industries. “We take on all types of total demo-

lition and also perform various types of rehabilitation work such as soil, asbestos and PCB removal. We recycle demolition rubble and have our own waste centre in the suburb of Botkyrka, where we also have our own recycling crusher,” says Anton. The company is based in Stockholm and it is also where the majority of the contracts are, but the business is nationwide and Lotus performs jobs throughout Sweden. The company is currently working on large demolition jobs in Örnsköldsvik, Borlänge and in Gothenburg.
Luxury apartments On Kvarnholmen in Nacka Municipality, where Anton works with the new Liebherr demolition machine from Liebherr, there will be a luxury area of beach apartments with stunning views over the water and Djurgarden. Lotus is demolishing about 60 grain silos in both concrete and steel. There are also offices and production facilities to be demolished. The demolition project is estimated to comprise thousands of tonnes of concrete and tonnes of scrap. The client is JM Construction and Lotus began working with interior demolition in mid-March. The demolition part of the job is to be completed by midsummer. Apart from the new Liebherr R 954 Lotus is also using a Hitachi 470 for excavation work. The dust from the demolition is suppressed by a Duztech water cannon next to the new Liebherr.
First demolition equipped Liebherr R 954 in Sweden “The new demolition machine from Liebherr is superb. Easy to work with, has comfortable cabin and good view. We did some research before we decided on a Liebherr. Among other things, we talked with colleagues
in Finland who were all very satisfied. Then it’s fun to be the first in Sweden with this machine,” says Anton. Liebherr has recently set up its own subsidiary in Sweden to support its customers and the new demolition excavators. “The machines are well designed and built to withstand tough conditions. It is very stimulating to be able to offer Swedish demolition contractors Liebherr’s wide range,” says Liebherr demolition excavator salesman Thomas Magnuson. “Our excavators are great machines and perfectly fit the Swedish demolition sector. In addition, we now have the industry’s broadest range of demolition equipment excavators.” Lotus got its new machine in September last year. After delivery it was fitted with the smart quick coupling system from Oil Quick for fast exchange of various demolition attachments. The machine is also equipped with all the demolition attributes you could wish for. The cab is reinforced, has hydraulic tilting and is protected to eliminate the risk of falling demolition rubble. The undercarriage has an extra counterweight, which is hydraulically removable. Also the tracks are hydraulically adjustable. The long reach boom has a length of 34 m but the biggest standard Liebherr demolition machine has a reach of 42 m. “I think the machine with Oil Quick was a spot on investment. It is easy to work with and I feel that Liebherr has invested a lot of power, flexibility and above all safety in their demolition range,” says Anton.
from 7.5 to 90 t. Lotus has also invested in a lot of hydraulic demolition tools. Most of them come from the suppliers SMC and Trevi Benne. They have about 10 cutters and pulverisers as well as many breakers in various sizes. The jobs are often managed by Lotus and they work primarily with their own jobs and not so much in cooperation with other contractors in the demolition industry. The company also operates its own transport. “If our demolition activity increases at the same rate as it has in the past two years, our hardware and tool fleet will almost certainly be expanded with both new machines and tools. There is no indication today that new orders will decline, but rather the opposite,” says Anton. Liebherr’s new R954 is a well-balanced excavator developed for heavy-duty demolition tasks.
Bright future for Lotus Since the demolition activity took off, Lotus Machinery & Transport AB invested heavily in both equipment and tools. Liebherr R 954 is the latest example, but before that they bought a Hitachi 470. Today there are 13 demolition excavators in the fleet weighing Issue 2 • May - June 2011 •

Demolition - a foc Volvo Construction Equipment is a company with probably the longest track-record in the construction machinery business. 180 years of sustainable development is something to be proud of. And for most of that time Volvo CE has stayed on top of their game. How a business enterprise can ever be that durable and competitive? Bill Law, Volvo CE’s Global Director for External Communications, answered that and other questions at an interview with PDi’s Andrei Bushmarin in Brussels. 180-year tradition of innovation “With over 180 years of history Volvo CE is clearly a company in the industry that can state we’ve been around as long as anyone and have been part of the shaping of the whole industry. From our spiritual home in Eskilstuna to the global business we’ve become, the company has been instrumental in bringing some of the greatest innovations to the market. To mention some significant milestones one could say the creation of the wheel loader in the early 1950’s or the world’s first series manufactured articulated hauler in 1966 Volvo has always been an innovator. In more modern times Volvo’s revolutionary care cab has set industry standards for safety or the critically acclaimed V-Act engine aimed at reducing emissions. There was an announcement of a new President and CEO at Volvo CE just recently. Who is the head of the company now? Pat Olney has taken over from Olof Persson since the beginning of May this year as Olof has taken up the role of CEO of the whole Volvo Group. Pat has many years experience in the industry and has been involved in many parts of the business from the finance side to overseeing the development of the global industrial system and developing the strategy that has been so successful for Volvo CE since 2008. A Canadian by birth, Pat has worked in many countries and since 2008 was a member of the executive management team. Do you expect any changes to the company’s strategy with the new man at the helm? As I said earlier Pat was one of the team who

PDi • Issue 2 • May - June 2011
was instrumental in developing our “fit for the future strategy” as such he’s clearly stated that his priority is to see the strategy fully and successfully implemented. As such you should not expect to see any radical change in direction. At the same time our business is always changing as is our market and the strategy will be adapted and fine tuned to take account of the changes we see in the world around us. Could you give us a snapshot of what Volvo is today: its core businesses, employee number, and the 2010 turnover? Volvo CE has grown dramatically since the late 1990s. With a number of strategic acquisitions the company capitalized on its Swedish base to become one of the leading providers of construction equipment and related services in the world. Building on its expansion in its core markets of Europe and North America Volvo has since gone really global. With the acquisition of Samsung heavy industries in 2008 Volvo became the first major foreign investor in South Korea and at the same time created a hub for its business in South East Asia, subsequent acquisitions in China have seen Volvo take the number one spot in this huge market in the excavator and wheel loader segment. Volvo today offers a full range of products and services in over 200 countries, with production facilities in 14 locations and more than 14,000 employees working hard to satisfy our growing global customer base.

A focus on demolition and recycling Since demolition and recycling are PDi magazine’s main subjects, would you describe briefly Volvo’s demolition and recycling range? Demolition and recycling is an area that has long been in focus at Volvo Construction Equipment and today we have a comprehensive range of dedicated machines. For primary and secondary demolition jobs, Volvo has six Standard Demolition Excavators, the EC210C, EC240C, EC290C, EC360C, EC460C and EC700C. Added to this we have four ultra high reach (UHR) excavators, with booms from 21-32m and high visibility cabs. We also offer a range of demolition attachments. What models of Volvo demolition excavators are the most popular with the customers? As is often the case, the more specialized the machine, the lower volumes will be sold of them each year. This is the situation at Volvo CE, with the most popular machines being the general purpose 20 to 30 tonne standard demolition excavators, which take a large slice of total sales in the sector.
What is, in your opinion, the reason behind their success? All models feature heavy duty fabrication, demolition guarding, good visibility and the industry leading Care Cab. The value of the Volvo brand is also important, which gives customers the assurance of product innovation, high productivity, fuel efficiency – and critically in this sector – industry leading safety features. Any plans to extend the current demolition/

recycling line-up in the nearest future? I’m afraid I can’t go into specifics. We try to avoid making announcements about future product development until we are ready to take them to market. But that said, we are commitment to customers in this sector and will endeavour to provide them with complete solutions for this important segment. This will, of course, mean new products will be added to this range over time. Let’s talk a little bit about a rather controversial
subject of ultra high-reach demolition applications (over 40 meters). Some manufacturers feel that it’s dangerous to go beyond the 40-meter threshold because it may jeopardize both the operator and the machine, and they refuse to build such machines on a serial basis. What is Volvo’s position on it? Safety is a core value of Volvo Construction Equipment and no one has a better reputation in the automotive industry. We don’t believe that there is an arbitrary height at which machines become ineffective.
What is important is that the machines are designed to work safely at their intended height – whatever that height is. Safety is our top priority and we have some of most talented and experienced experts who really understand the key issues of designing demolition machines that work at extreme heights. What is your outlook on the demolition industry? Do you feel that this business is now past the recession and growing? The demolition segment is set to improve on the Issue 2 • May - June 2011 •

all over the world striving for the top and often failing. Volvo, on the other hand, has been staying on top for decades, if not for centuries. What, in your opinion, sets the company apart from the competition? Clearly one of our strong points is our long history. Volvo has not only seen the industry evolve but has been part of it. When customers buy Volvo they know they are buying a brand that they can trust, a company who will be with them whatever the weather in the market. There’s also the product innovations like CareTrack that show Volvo is on the cutting edge of technology or our focus on fuel efficiency experienced in recently launched technology such as Optishift in larger wheel loaders which makes machines up to 15% more fuel efficient or our eco operator program which shows how operators can utilize the machines more efficiently. On the whole I think what sets us apart from our competitors is our core values which are part of everything we do – quality, safety and minimizing our impact on the environment.
Up-to-date approach to marketing
back of a generally rising tide of recovering world economies, especially those in the more mature markets of Europe and the US, where there is a greater need to reuse existing inner city sites. Looking longer term, the need for specialized machines to safely and efficiently recycle structures is set to grow on a global basis in the future.

Where there is a customer in the world Volvo CE is not far away… How many countries does Volvo supply its machinery into? Over 200 countries and territories. What are Volvo’s biggest markets at the moment? Together with our home markets of Europe and North America the most growth we have seen is in Asia and in China in particular where we have reached a number one spot with our main product offering. The question to you as Director for External Communications: how important is for Volvo the Internet and its social network services like Facebook and Twitter in terms of communication, marketing and promotion? What is important to me is the content & quality of the messages that we need to communicate to our external stakeholders. As the world increasingly uses new media and online communication to seek and send information so we see its growing importance. I have no crystal ball that helps me identify exactly the impact online tools will have on marketing and communication but I can tell you that we are looking at all tools in this area to ensure that we are taking advantage of what’s out there in the best possible way. To round off our today’s conversation, what is your forecast for 2011? Do you expect it to be a good year for the industry in general and Volvo in particular? We see the broad recovery continuing. Our forecast for Asia remains strong and our estimations for the increase in our markets in Europe and North America have been revised upwards by around 10% market growth year on year.

Volvo demolition excavators cater to a variety of needs With additional hydraulic options and protection systems, Volvo Construction Equipment excavators are tailored to the demands of heavy-duty demolition sites.
Addressing the varied – if specialized – needs of the demolition sector, Volvo Construction Equipment offers a wide range of demolition excavators adapted to cope with the rigors of demolition duties and provides both high reach and standard packages to meet the needs of contractors.
Three ultra high For extended reach, Volvo offers three Ultra High Reach demolition models: the 21m-reach EC360CHR, the 27m-reach EC460CHR, and the 32m-reach EC700BHR. All Volvo HR machines can be provided with both high reach equipment and a standard boom and arm configuration. The ability to switch from one type of equipment to another with ease facilitates a return on customers’ investment. And a hydraulic modular joint enables a 30-minute quick change from demolition to standard backhoe attachment, boosting machine utilisation when not required for high reach projects.
Six standard demolition rigs Supporting the HR range are Standard Demolition packages developed around the standard C or D-Series crawler excavator models - the EC210, EC240, EC290, EC360, EC460, and EC700. These “factory fit” demolition packages ensure operator protection, first and foremost, as well as the necessary protection for the machines themselves – a factor that can considerably improve resale values. At the same time, hydraulic upgrades allow the machine to act as a multi-function tool carrier. With operator safety and machine protection the key considerations, the Volvo concept is to provide a completely specified demolition package. To avoid the situation where customers overlook important options, Volvo’s concept packages everything together, with all demolition-specific features included, so the customer does not have to worry about which options to order. The unique feature of these demolition options is that they are all ‘bolt-on’, so no more welding is necessary in the event of anything needing to be replaced due to wear or damage. This results in less machine downtime, with the obvious impact that has on the profitability of the customer’s operation. Standard features included on both HR models and in the Standard demolition packages include: • • • • • • • •
Bucket and boom cylinder guards, to protect rods and cylinders from falling object damage. Swing ring protection guard to protect the swing ring bearing seal and grease piping from damage by rebar, timber, concrete or other rubble. Frame-mounted, falling object guard (FOG). Bars on the front of the guard are set at angles to increase forward visibility. Micro-mesh screens on doors and engine cowl to keep out fine particles that could result in overheating and impede engine performance. Double thickness side doors on both sides of the superstructure to protect pumps and coolers in the event of side impact. Bolt-on Side Impact Protection system to defend the superstructure from damage. Enhanced 8mm under-guarding (10mm under the slew ring). Full-length track guards to repel demolition debris and prevent rebar or other sharp objects lodging in the tracks.

Hired shot blasters aim up at reservoir
Demolition at a lofty height The panoramic German restaurant on the Drachenfels, or Dragon’s Rock, above Königswinter in the Siebengebirge National Park on the River Rhine is being replaced by a modern glass cube. The whole plateau at the summit is being conditioned to accommodate growth in tourism. An Atlas Copco CombiCutter CC 2500 U has managed to demolish the old restaurant under difficult conditions. To begin with, the access road to the restaurant was iced over for weeks, making it impossible to drive. Once the road was clear, the retaining wall along the road needed to be reinforced in parts to take the weight of the 25t Cat 323 D excavator and the CombiCutter. No rubble was permitted to fall down the hillside and as a result, the outside walls needed to be taken down inwards towards the excavator. Time was also a pressure on foreman Olaf Goldschmidt and his team from Dortmund-based Stricker GmbH & Co. KG. Demolition work had to be completed by the end of February due to strict
requirements regarding the protection of wildlife. Residents, visitors and the media also showed great interest in the progress of demolition work. “I have never had so many curious onlookers and representatives of the press on a building site,” says Olaf Goldschmidt. “The work attracted enormous interest.” The team managed to complete all demolition work in good time. Construction began on a new restaurant in May, 2011. Featuring a large glass cube design, the building will also boast a spacious forecourt for visitors. The remodelled plateau will be officially opened at Easter 2012. The regional government will bear most of the costs of about EUR 8million.

A 300mm shot blaster removes coatings from the steel base of the reservoir. In Australia two self-propelled shot blasters, hired from Kennards Concrete Care, helped with the refurbishment of Canberra’s main drinking water reservoir. The 415v, 250mm and 300mm shot blasters were used to remove original coatings on the steel base of the 33 million litre capacity tank before the 4400m2 area was recoated. ACG Industries, part of the Ausgroup of companies, was contracted to undertake the work at Mt Stromlo Reservoir for ActewAGL, the multi-utility, which provides electricity, natural gas, water and wastewater services to the capital. This was the first refurbishment of the
reservoir in about 20 years. “Pot blasters are very efficient, but they create so much dust you can’t do anything else, such as priming, at the same time,” said ACT projects manager Kerry Woodbridge. “The shot blasters produce minimal dust, which allows a full team to work alongside. We needed to achieve a surface profile of between 40-70 microns. The rounded steel shot did the heavy stuff, and removed the bulk of the coatings, and we then went over it with a pot blaster. The recyclable nature of the shot is a bonus.” Kennards Concrete Care has hire centres in Sydney, Brisbane Melbourne, Adelaide and Perth.
the equipment involved allowed us to complete the works in less than 120 days,” says Barreto. “Considering the demolition tools available, the hydraulic breakers continue to be the most requested. They differ from the more specific
attachments, such as pulverisers and demolition tweezers. The first are the ideal choice for recycling of rebar and concrete, whilst the latter are more for demolition on sites of difficult access, as they are heavier and require more robust machines.”

Atlas Copco breakers assist demolition in Brazil As bid winner of the biggest refurbishment contract at the Mineirão Stadium, in Belo Horizonte, in the Brazilian state of Minas Gerais, contractor Detronic had the challenge of demolishing the entire bleachers area, where seats will be installed. The company used several Atlas Copco hydraulic breakers for the project. The company’s civil works included the lowering of the field by 3.9 m, which required the removal of 70,000m2 of earth and the demolition of electronic scoreboards and indoor stadium rooms. To handle the work the company developed
48
a demolition plan, which involved the opening of accesses to allow entry of large equipment. “We used the 140 kg hydraulic breakers SB 152, mounted on 8t mini-excavators,” says Detronic executive officer Ayres de Azevedo Barreto. “Only small equipment like those could move in the limited area we had in the first stage of the construction.” After creating access for the larger equipment, Detronic started demolishing the bleachers using larger breakers, such as the SB 452, MB 750 and HB 3100. The attachments were mounted on machines of up to 50t, demolishing 2,500m3 of concrete. The engineering plan devised by the company programmed for the demolition of Mineirão Stadium and the lowering of the field to be completed in 150 days. “The high productivity of

Demolishing for new luxury hotel in Berlin In the immediate vicinity of the Berlin Zoo Palast company United Harvest Enterprises (situated in Abu Dhabi) invests on the Kantstrasse in building a luxury hotel. This result in a filled up gap in the capital of Germany. Meanwhile the dilapidated old buildings have become a nuisance now and disappear piece by piece. By building a new 118 m high hotel complex another grubby street corner is closed. Furthermore, there is a need for additional parking space, and this done by creating a four-story parking garage underground. To realize this task, the pit reaches it final four-story deep with the help of improvised floors. After the predetermined depth was reached, they could start with the construction of the parking deck. Due to the design and load specifications the parking deck floors had to be built in modular construction. The improvised floor was demolished and then to built the final ceiling of the parking decks. In this way, three improvised temporary floors had to be removed taking into account their very limited weight exposure. The company Kanellos GmbH of Berlin, that was in charge with the demolition work, took the 40 cm thick and heavy reinforced concrete with 28 mm rebar away within a short time, by demolishing the three floors with a total of 5.100m2 heavy reinforced concrete slabs. The crushed material was recycled for re-use. For the demolition of the heavily reinforced concrete ceiling demolition contractor Kanellos had used a FRD concrete and steel shear type VC22FT. The product VC22FT out of the FRD full line a shear type with a service weight of about 2300 kg, a jaw opening width of 895 mm and 530 mm long steel cutting blades could be used universally. The breaking of concrete structures became easy and cutting the rebar is clean and no additional time consuming dangerous gas cutting by hand is needed. Other FRD equipment that was mounted on a mini-excavator was a hydraulic breaker FRD F3-LN for trimming and cleaning out of the corners. The company Kanellos GmbH was able to continue their professional work without using landfill space for most of the demolished material. Wolfgang Gust plant manager was very pleased with the performance of the FRD products. Attending area dealer company Reinhard Kienbaum was providing the fast and competent technical services and job site assistance. The completion of this new luxury hotel is planned for late 2011.

General Equipment Company Introduces the CTS12 In the US the General Equipment Company has introduced the CTS12 Rip-R-Stripper for floor covering removal projects. This new machine offers a fresh solution to the old problem of removing ceramic tile, hardwood floor and other tough floor coverings. The CTS12 acts as a tool carrier for electric powered breakers, including popular models from Hilti, Bosch, Makita and Hitachi. Unlike the random orbit-type tile stripper machines currently on the market, the CTS12 provides a direct impulse force, which supplies power to break through the high bond strengths of mastics, glues and thin-set materials. The CTS12 allows users to operate electric powered breakers in an upright position. In addition the handle is adjustable to enhance operator comfort, and is rubber-insulated to reduce vibration. The handle also folds for storage and transportation. Breakers mount quickly to the CTS12, and blow force angles can be easily adjusted to accommodate varying material types and bond strengths. The unit operates from a standard 115VAC, 15A power source.

Bingo! Full house for JCB high reach demolition rig A leading Scottish civil engineering and demolition contractor has bought a JCB JS330 HRD tracked excavator, featuring a high reach demolition rig, to carry out a series of prestigious demolition projects in the North of Scotland. The machine was purchased by W Munro Construction, based in Alness in the Scottish Highlands and supplied by dealer Scot JCB. The 21-metre JS330 HRD – which comprises a three-fold boom fitted to a specially adapted demolition specification JCB excavator – is pictured here in Inverness dismantling the Carlton Bingo building in preparation for a new development by Premier Inn. Roderick Munro, General Manager of W Munro Construction, said: “We chose the purpose-built new JCB model to further enhance our specialist expertise in controlled demolition. It becomes the only high reach demolition rig north of Dundee and gives us a significant advantage when tendering for major projects. It is the perfect machine for our requirements and is working well.” William Munro Construction (Highland) Ltd - incorporating Munro (Highland) Ltd - was
established in 1977, initially to provide building and civil engineering solutions to clients including Highland local authorities, oil platform construction companies, housing associations, distilleries and private developers. Over the last 30 years, it has produced high quality project services and is a member of the Federation of Master Builders.

Atlas Copco attachments reduce bridge demolition time by 25% The specialist demolition team of the Hasseltbased BVBA Baldewijns & Co, faced a tough challenge. They had to remove two 100 m long bridge sections of the E 313 over the A2 highway at the Lummen highway interchange over a single weekend and remove the rubble. On Friday evening, after having laid a sand bed to protect the underlying asphalt road, 12 excavators were put to work with heavy breakers and concrete crushers. The most powerful breaker on the site was an Atlas Copco HB 3000, and suitable for excavators in the range of 32 to 50t. It is a robust tool that can handle heavy demolition jobs; a real production machine, 7 days a week, 24 hours a day. A total of 4,000m3 of concrete was de-

works, trade waste management, recycling and skip hire. Introduced in response to growing customer demand, an innovative modular system on the JS330 HRD provides greater versatility on site by providing the optimum boom configuration for each demolition task. With the new system, the high-reach boom can now be hydraulically disconnected into a docking cradle once the high level work is complete. The specially adapted JS330XD base machine can then pick up a
two-piece boom which is designed for medium height demolition, or for working at ground level and below. In addition to the specialist boom configuration, it features heavy-duty mainframes, undercovers, side buffers, turrets and track motor guards, extra duty dippers and linkages. With a FOPS cab guard and cyclonic engine pre-filter for dusty conditions, it is well equipped for a long life on the toughest demolition tasks.
molished, sorted and removed, including 300t of reinforcing steel. The job was completed in only 40 hours, far less than the scheduled time of 55 hours. This impressive result was primarily achieved by thorough planning with a tight schedule, sufficient equipment, and, the 45 professional operators. The starring role was played by the newest concrete cutter from Atlas Copco. The CC 6000, equipped with universal jaws that made it possible to cut through and crush the bearing beams of the bridge and then cut through the heavy reinforcing bars. “We needed really heavy equipment to get this job done within the schedule,” says Baldewijns & Co director Steven Lisens. “The CC 6000 concrete cutter contributed to the smooth progress of the works and the final result. The cutter had no problem at all with the size of the beams. Its crushing power and
high cycle time exceeded all of our expectations. The performance and the reliability of the products from Atlas Copco have really convinced me. The results achieved with the CC 6000 and the HB 3000 have inspired us to purchase a new Atlas Copco HB 4700 hydraulic breaker.”

New 710 V Classic hydrodemolition robot from Aquajet Systems Hydrodemolition equipment company Aquajet Systems has launched its next generation Aqua Cutter 710 V Classic series of robots offering improved automatic and manual options. The new model is ideal for working on bridges, tunnels, roads, walls, parking garages or ceilings. Working with a typical 1 000 bar pressure and 250 l/min, the robot handles removal depths to approximately 1 000 mm of concrete if required. Aquajet has recognised that there is a frequent demand for its hydrodemolition systems with reduced computer control allowing manual handling with, for example, flow control valves for oscillating speed, roller speed, lance angle speed and mechanical stops for operation widths and lance angles. Improvements have been made to the settings of programmes with several parameters easily selected and adjusted on the colour display with multi language operator instructions. Aquajet robots are equipped with the patented Equal Distance System. Regardless of the set lance attack angle, the system controls and maintains the nozzle’s distance from the concrete surface. Maintaining an optimum distance, EDS ensures that no power is lost due to the nozzle being too far
from the surface, which will ensure a 15 to 20% increase in removal capacity. The lance attack angle can be set from –30° to +30º allowing for efficient removal of concrete under rebars. The patented Intelligent Sensing Control is an advanced sensing system and features no electronics, resulting in a more efficient production with less stops due to problems with sensors. To t a l l e n g t h v a r i e s from 2.65 meter – 2.85 m and the new unit is 2 meter wide. Minimum height is 1.42 meter and, with a sturdier base, an extended free vertical reach of up to 7 meter is possible and a 4 m width operation. The variable width chassis provides maximum stability during set up and operation. In its narrow version, access to the tightest passages like doorways, alleys, footbridges, is possible. The variable track width extends from 1.04 meter to 1.64 meter and the unit weighs 2.3t. A new improved rubber lined splashguard on the power
head ensures improved noise reduction. Easy service access is also assured with gull wing hoods and fold down hydraulics for cleaning and maintenance.

was able to expose the rebar with no damage, allowing it to be reused for the replacement beams. ISOTEC’s hydrodemolition contract on both bridges was completed within 20 days with the damaged beams lifted clear and replaced in two night time operations by main contractor ICAFAL. Hydrodemolition is a relatively new concept in South America, but widely used throughout Europe, with ISOTEC leading the way in Chile. The company had initially specialised in high pressure water cleaning. “Taking advantage of this experience it was logical to expand our business in to hydrodemolition, taking delivery of the new Aqua Cutter HVD-6000 from Swedish manufacturer, Aquajet Systems,” says Jose Alday.
Hydrodemolition technique
Chilean bridge beams replaced with hydrodemolition Following earthquake damage to two bridges over the Santiago’s Southern Approach (Acceso Sur Santiago) highway in Chile, hydrodemolition specialist contractor ISOTEC Ltda relied on an Aquajet HVD-6000 Robot to assist in removing damaged concrete beams and retain the rebar. The 46 km long recently opened highway has been designed to relieve traffic flow on the Chilean capital’s southern approaches to handle up to 25 million vehicles per year. According to ISOTEC’s Jose Alday, the role of the Aqua
Cutter was to remove the concrete above the beams allowing them to be lifted clear and replaced, whilst saving the rebar for reuse in installing the replacement beams. “The hydrodemolition technique proved ideal with no collateral damage to the remaining structure whilst removing the damaged concrete,” he said. “We also had to guarantee minimal impact for the highway users, allowing the highway to remain open throughout the removal process.” Operating to a depth of up to 200 mm, the Aqua Cutter
Concrete rehabilitation using hydrodemolition is becoming an increasingly important aspect of civil engineering and building renovation projects. Applications can involve cleaning, roughening, removal of deteriorated concrete and even cutting. Water jetting is actively used for the removal of chloride damaged concrete layers down to the reinforcement bars or to a depth where the chloride content is at or below the permissible level. It causes no damage or vibration to the existing rebar and prevents damage or loosening of adjacent concrete and parts. Using a high-pressure jet of water, supplied at a pressure of 1 200 bar and a flow rate of 200 litres/min by the company’s Woma pump, coupled to the HVD 6000, the Aqua Cutter robot was able to blast the concrete without causing any damage to the reinforcement bars or adjoining concrete. The Aqua Cutter robot from Aquajet is considered the most advanced offering a wide variety of features ensuring top quality results are achieved safely at a high production rate with low operating and on-going costs.

The success factors of a productive wall sawing job Wall sawing has evolved throughout the last couple of decades. The first tools were heavy and bulky, mainly hydraulic systems with practically no automation. Today we observe a clear tendency to more
This technology offers a higher degree of efficiency than conventional hydraulic systems and a much lighter system weight. In the last decade the race in the wall sawing industry was dominated by building the saw with the highest performance of the market. This tendency has certainly brought productivity to another level and the effective sawing time has been reduced to a level that it only takes a relatively small share of the total application. On an average sawing job a saw is running only a few hours per day, the rest of it is spent with transportation, installation and removal of the equipment. This means, on a regular working day an operator will be sawing less than 20% of the time. An important leverage to improve the total application time is not depending anymore so much on the saw speed, but mainly on how fast the equipment is being brought to the jobsite and installed. Especially on jobsites such where single doors or window openings have to be cut out and where the saw has to be constantly moved from one floor to the next, the ease of transport and installation comes much more into play than the sawing performance of the equipment.
compact tools that are driven with electric high frequency technology. 54
Transport and set up time gets more important To reduce effort a trolley can facilitate a lot the transport from the van to the sawing location. Manufacturers offer convenient transport trolleys that can take all the necessary sawing material and be brought to the desired location by a single person with much less effort in one go. Depending on the distance this can drastically reduce the transport

time and will save energy of the operator. Once the saw is on the desired location it has to be installed. This part of the application takes up a big share of total application. A smart sawing system should be able to be fast and easily installed.
Latest hype – new wall saw from Hilti Fewer and handier parts make a system more efficient. As some of the saws are still quite heavy, some manufacturers work with a modular system, where, for example, the saw head can be dismantled into smaller, more handy parts. This brings certainly some advantages, as the single component can be easier transported and installed, but has also its downside as the operator has one component more that he has to assemble or dismantle. The latest hype is the new wall saw of Hilti, the DST 10-E. A regular high frequency wall saw needs a separate electro box that makes the electrical conversion to high frequency. This new saw integrates the electronics already in its saw head, so no separate e-box is needed. This concept saves time when it comes to transport and installation of the system and will improve total application time much more efficiently than a higher performing saw. The real time gain is achieved with the reduction of the transport and set up time of the equipment, especially if the total amount of sawing is 2m2 and less.

Competition inten in tracked mobile
The trend towards mobile crushing, screening and recycling plants on tracks is certainly continuing. ConExpo showed that the established manufacturers designed new units with all sorts of new features, but there is also a number of new manufacturers, particularly American, that want to jump on the bandwagon. PDi’s Heikki Harri reports. It will not be easy as the number of companies offering all sorts of attachments is increasing, as well and the competition is fierce. Many manufacturers also made global launches offering potential customers something new. There were no revolutionary innovations, but a lot of new features. Customers face problems trying to determine which of the new features really are significant and will make a difference. PDi takes a look at the demolition and recycling related machines on show at ConExpo, particularly those new to the market.
Sandvik Naturally the big players offered more than the smaller ones. Sandvik launched nine new products, one drill, two screening plants, three mobile crushers and three small breakers. The three new breakers, named BR555, BR777 and BR999, are designed for carriers in the weight range from 1.9 to 12.5t. The carriers can be skid steer and backhoe loaders, and mini excavators. They are also designed to be added to the product offering of rental companies. Sandvik also was one of the companies offering new screening machinery. The new QA331 three-way split screener is an upgrade of the former QA330. The machine is able to work at a quarry face, inner-city development project or a recycling centre. The other new piece of machinery was the QE440 mobile scalper screen. There were also two track-mounted impact crushers on display. The QI240 is designed for demolition and recycling and also for a smaller quarry operation. It is fitted with a pre-screen for scalping of the fines in order to prevent the undersize material passing through the impact crusher.

of the five tracked screen family. In addition to quarry and contract crushing of aggregates the machine is suitable for screening concrete and other waste materials. Metso also revealed their future project of a new screening method called Ellipti-Flow. According to the company, the system is able to monitor all screening related parameters and increases the screening efficiency by up to 30 percent in comparison to a nominal banana-type screen of the same screening area. It will be launched later this year.
Terex – Powerscreen
This maximises the throughput and reduces wear costs. The QI440 is another model with a larger impact crusher.
Atlas Copco Here is another global manufacturer that showed various types of machinery. For the demolition and recycling sector the company offered a track-mounted crushing unit and several hydraulic breakers. Atlas Copco acquired the Powerscreen (Powercrusher) range of track-mounted crushing and screening units from the Austrian Hartl last year and showed the first new unit in Atlas Copco colours. It really seemed to fit very well in the Atlas Copco large family of products. The Powerscreen (Powercrusher) product range includes four jaw crusher, six impact crusher and one cone crusher models and six screening units. In the breaker side the company introduced the HB 10000, rated the most powerful heavy hydraulic breaker in the world. It is suitable for carriers from 94 up to 154t and applicable also for demolition of large concrete structures. On the lighter side of hydraulic breakers Atlas Copco introduced a new generation of handheld hydraulic breakers with improved vibration characteristics. The weight ranges from eighteen to forty kg.
Metso Metso is another global manufacturer from the Nordic countries like Sandvik and Atlas Copco. This time Metso’s focus was in screening. The launch machine was the track-mounted screening plant Lokotrack ST3.5, which is the second smallest member
Powerscreen is the Terex division in charge of tracked mobile crushing, screening and recycling machinery. In Las Vegas, Powerscreen showed four units that can be applied in demolition projects, as well. The Powerscreen XH500 is equipped with a horizontal shaft impact crusher and is designed to process soft to medium hard primary and secondary materials, including asphalt, recycling and demolition waste. The model XH320SR is a smaller unit with an impact crusher also applicable in recycling and demolition. The XA400S is a jaw plant designed for quarrying, recycling and demolition applications. The Powerscreen Warrior 2 400 is a large-scale screening unit that is able to handle aggregates, topsoil, coal, and construction and demolition waste.
Allu This is a Finnish manufacturer best known for screenercrushers. Once again at a show, their on-stand demonstrations attracted a continuous flow of potential customers and other viewers. Allu had the opportunity for a special celebration. Year 2011 marked the 20th anniversary of the company’s original and revolutionary idea, the screener-crusher. Although the machine was launched in 1991, it can still be regarded as revolutionary, since the working concept continues to be fairly unknown. This is why Allu organises demonstrations at most exhibitions, which is the easiest way to spread the word and convince onlookers. The number of companies offering machinery and attachments for demolition and recycling continues to increase. Nevertheless, the old and established players were also present, such as Astec – KPI-JCI, Stanley – LaBounty, Wirtgen – Kleemann, Eagle, Lippmann, Rubble Master, Furukawa, Chicago Pneumatic, Allied-Gator, REMU, Red Rhine to mention a few. Customers need to look closely to determine which equipment can best suit their projects and the near future will show which are the fittest companies. Issue 2 • May - June 2011 •

Mini crushers vs large scale crushers There has been a view that crushing concrete is only for large-scale stationary crushers. Mini crusher manufacturer Red Rhino claim that yet never has that been further from the truth than now. “Crushing concrete on site with a mini crusher makes sound financial sense. Mini crushers can get into the smallest of places and crush the concrete exactly where it’s needed. The portability of the Red Rhino mini crusher means that a 10t payload lorry can now transport the crusher from site to site,” says Jason Purllant at Red Rhino.
Red Rhino mini crushers can work in smaller spaces than a traditional large-scale crusher, yet still achieve up to 45t/h. The Red Rhino mini crushers as their name suggests, are strong, tough, and capable of crushing even the hardest rubble. Red Rhino owners have recognized that purchasing and maintaining a mini crusher can really save them money. The running costs of a mini crusher are in the £100’s not £1000’s per year. This is now a genuine alternative to a traditional larger crusher.
Opportunities for a Red Rhino Mini crusher The construction and demolition industry currently produces 120 million tonnes of waste every year. Around 20 million tonnes of this waste ends up in landfill with no reuse and no intrinsic value. The UK is spending £4bn to dump waste in a landfill site. In terms of sales, Red Rhino sales and marketing manager Jason Purllant reports that the increasing pressure to recycle demolition waste in the most cost efficient way has led to sales volumes rapidly increasing. Waste transfer stations are also becoming increasingly aware that there really is a genuine alternative to large scale crushing. This rubble really does have a value. Why are we dumping it?
Red Rhino 7000 series in Demolition Red Rhino products work on a very simple action that calls for two jaws, set in a vee. Material entering the top becomes progressively crushed as it slips down into the ‘V’ until they are small enough to fall through the gap at the bottom. The size of the finished material is governed by the width of the jaws. Output can vary from 10mm to 140mm depending on the settings of the hydraulically adjustable jaws. The Red Rhino 7000 series offers a fully wireless control system. This allows operators to be clear of the machine or alternatively to operate the crusher from the comfort of their own excavator cab. Operating machinery from a safe distance is so

important on large-scale demolition sites. “Our 7000 series crusher represents a genuine alternative to it’s a bigger brother but at a fraction of the costs. The little brother however is far more portable weighing in at just 10t and an overall length of 6.7m and 2.2m wide. With a 700mm x 400mm jaw size this crusher can be sat in the smallest of gaps and crush even the largest rubble. The recession is biting and every company should consider how it disposes of its rubble and the costs associated with this operation,” says Jason.
The Future “The use of smaller crushers in the demolition industry is set to grow as people realize that big isn’t always better. Mini crushers like the 7000 series will provide cheaper owning and operator costs compared to the more traditional large-scale crusher,” says Jason.

Rubble Master conquers Swiss mountains “High, higher, highest” would be an appropriate motto for the sporting achievements of Rubble Master in the Linthal Power Station project in the Swiss Canton of Glarus. This time the 28t RM100 reached even greater heights, climbing to 2,500m above sea level with the material cableway. The challenging journey was made more difficult by the fact that the second cableway is designed to handle a maximum load of only around 28t. The task awaiting the RM100 in this new construction phase was to crush 25,000t of limestone that had been blasted from the mountain to make 0/70 aggregate, with the machine processing 180t/h. Linthal machine manager Jonas Wyrsch is full of praise for the RM100’s performance in the extreme conditions. “The RM100 is reliable, maintenance tasks are easy and it simply gets on with the job, plus servicing through the local Rubble Master dealer BUV Biedermann Unterhalt & Vertriebs GmbH works perfectly and is exemplary throughout the entire operation,” says Wyrsch. Once the job was finished at the end of October the RM100 was taken down to the valley station using the cableway. The
current construction stages in the Linthal 2015 project are the driving work for the pressure tunnels and the machine and transformer cavern which measures 150 x 30 x 50 m. Work on the concreting of the dam will begin in summer.

ConExpo a clear sign for a change for Rockster Recycler The ConExpo in Las Vegas, held at the end of March 2011, has shown that there is already a changement in the market and the customers are more willing to invest again. And this was more than positive for the Austrian producer of mobile crushing plants “Rockster Recycler”, who have shown their latest machine, the track mounted Impact crusher R1100. The team stated a huge amount of visitors during the exhibition and were more than happy to announce also some direct sales. It was the debut of Rockster Recycler at the ConExpo, and the perfect platform to acquire new customers on the North and South American market as well as Canada and to socialize with dealers for the expansion of the worldwide network. But not in the wildest dreams, the CEO of Rockster Recycler, Wolfgang Kormann, thought of such a run of visitors. “I was sure, that there is a change of tendency in the market but never expected such a crowd of visitors at the ConExpo. Furthermore the customers

were well-informed experts, who already monitored the products on the market and knew the requirements they expect from a crushing plant. Therefore it was easier to inform them more detailed about the advantages and technical features of our products,” explained Wolfgang Kormann, who was on site together with the CPO Norbert Feichtinger and Stephane Guerchon, the CEO of Rockster North America. Rockster presented their latest development, the 32.5 t impact crusher R1100, which draw the interest of the customers through its optimal measures, the high performance of up to 350 t/h and the mounted 1-deck-screenbox and the return belt. “With the combination of the crushing plant with the screenbox and return belt our clients have the possibility to produce defined high quality materials in one workflow and this also on the smallest jobsites through the optimal measures and flexibility of the whole system. With our modular concept we are able to react
PDi • Issue 2 • May - June 2011
anytime on the requirements of the customers and can offer the perfect plant for their demands,” says Kormann. Stephane Guerchon explains the advantages of the Rockster concept and was highly satisfied with the shown interest of the visitors on the Austrian crushing plants. “For sure it was beneficial to present the impact crusher R1100, as this allowed us to show and explain the special features of our system and to convince also the operators and service engineers of the easy handling and maintenance of our plants”, says Guerchon. A special feature of the Rockster mobile crushers is the patented Duplex-System, which allows the exchange of the crushing units (from Impact crusher to Jaw crusher - and vice versa)
on the same basic machine and offers the customer a big advantage in the operation of the plants. “Our unique and patented Duplex-system enables the customer to cover a wider range of applications and to optimize the machine utilization. Through the hydrostatical driving unit, which allows a clockwise or counterclockwise rotation of the crusher, both units can be installed on the same chassis and changed in shortest time (about 3 hours) from Impact crusher to Jaw crusher - and vice versa. Therefore the crusher can be tuned fast and efficient for the different requirements and offers to cover a wider range of possibilities. Furthermore this saves also resources in the plant engineering” says Guerchon.

JCB Equipment steps forward at futuristic waste facility A pioneering waste treatment and recycling firm has purchased five JCB Wastemaster models to enhance productivity at its state-of-the-art mechanical and biological treatment (MBT) plant in Leicestershire. New Earth Solutions has bought the machines – a JCB JS220 Materials Handler, a JCB 541-
70 Loadall telescopic handler, a JCB 180 skid steer loader and two JCB 426 wheeled loading shovels – to perform waste rehandling duties at its new Cotesbach MBT plant near Lutterworth. Focused on technologies and processes, which recover value from waste and reduce its impact on the environment, New Earth
Solutions opened the revolutionary facility in October 2010. The site uses the latest mechanical sorting equipment, advanced bio-filters and automated monitoring and control systems, with all processes fully enclosed. It has the capacity to process 50,000 t per year of waste wand is underpinned by a contract with Lafarge Aggregates Ltd to treat Leicestershire’s household waste over a 5 - 7 year period. Graham Roberts, New Earth Solutions’ Site Manager at Cotesbach, said: “We assessed the available equipment on the market and the JCB Wastemaster package met our requirements for performance, service support and cost. The machines are performing well and contributing to the ambitious overall efficiency targets at this brand new site.” The JCB models are forming an integral part of operations, with the JCB JS220 Materials Handler initially used to select and load waste into the hopper, which feeds through to the sorting plant. Operating in confined spaces, the JCB Loadall and skid steer loader are then used to handle the recycled material.
New Generation Eagle 2 MBI Shears from INMALO International Marketers (London) Limited (INMALO), the sole UK importer for the Italian Mantovanibenne (MBI) range of excavator attachments, has introduced the new Eagle 2 range of MBI shears for the demolition and recycling industries. Superseding the Eagle 1 series, Eagle 2 spans operating weights from the 160kg SH10 to the SH900, which weighs 10.2t. Carrier machine weights are from 2 – 250t. In development for 2011 are the SH1500 and the SH2500, 15 and 25t shears respectively. Developments on the Eagle 2 range include double adjuster guide rams, a new jaw, power valves for shorter cycle times, fully butting blades and front cutter, larger cylinders and 360° dampened hydraulic rotation, which prolongs motor life. The range also includes non-rotating models of between 1.7 and 8.5t. An optional bolt-on piercing tip is available.

Recycling success with new lokotrack St3.5 Metso’s mobile screen Lokotrack ST3.5 has proven its efficiency in a demanding screening project involving rock-based recycling materials in Italy. In Pollenza, south of Rimini, ST3.5 classifies difficult, rock-based recycle materials with a capacity of about 1,000 t/day. Thanks to the optional vibrating grid, the screened end products remain consistently very clean. Re.i.cal., a family owned company, operates a stationary quarry for producing aggregates needed for concrete. A few years ago the company expanded its operations to recycling. “We plan to use our Lokotrack ST3.5 both in recycling and quarrying. Thanks to its compact size, the unit can be easily transported on a normal trailer, which is a big plus for us,” says Re.i.cal managing director Andrea Renzi. “Our first impression of ST3.5 is very positive, thanks to the quality components, sturdy design and ease of use. In recycling, having a small shredder before the mobile screen is like a Fiat
competing with a Ferrari, so we cannot verify the full capacity of the ST3.5 yet.” An optional, vibrating grid is available for the Lokotrack ST3.5. In quarrying, it results in quicker feeding and reduces the need to tilt the grid for cleaning. In recycling, the main benefit is in securing the cleanness of the end products. “The vibrating grid effectively separates wood, plastic and other scrap from the feed, giving us much cleaner screened end products. By choosing different grid mesh sizes, we can also easily adjust and control the feed size to the screen,” says recycling manager
Massimo Renzi. With the ST3.5 mobile screen, the upper screen deck houses a 30 mm mesh size, and the lower deck 5 mm. Oversized materials separated by the grid are returned to the crushing stage. Fed by the small Italian shredder, the output in recycling is about 130t/h. The Lokotrack ST3.5 used by Re.i.cal. also features separate remote radio controls for the mobile screen and the vibrating grid, allowing total steering and adjustment of the screening process easily from the excavator or front-end-loader cabins.
Making sand from glass The production of sand by recycling glass is a developing market in Australia, and Alex Fraser has been supplying asphalt plants for five to six years with product from various crushing methods. After an impressive couple of months using a rented Pilot Crushtec TwisterTrac AC210, the Alex Fraser group purchased one of their own. The company’s recycling project manager Brent Alford says that Alex Fraser has invested considerable time and money into the research and development of recycled glass sand as a
62
PDi • Issue 2 • May - June 2011
viable product, and there is still a long road ahead. “We are in the development stages of releasing a high quality sand replacement product into the market and the TwisterTrac was an integral part of the crushing, screening and cleaning process that we have put together,” says Alford. Working in conjunction with other crushing equipment, the TwisterTrac produces two products at the moment, recycled sand of minus 10mm and recycled sand of minus 5mm.The material used for making sand would normally have gone to landfill. “It is now the case that recycled concrete is seen as an equivalent product to the virgin rock product it is competing with. Recycled sand has already met with considerable success as we recently delivered recycled sand to a large pipe line project where our product was compared favourably to the best pipe bedding sand from local sand quarries,” says Alford.
IronHustler’s Dust Supression
IronHustler estimates that the company saves six hours of labour per day during demolition and recycling activities, thanks to the DB-60 from Dust Control Technology. When IronHustler president Dave Schielein began investigating alternative methods of dust suppression on demolition and recycling projects, the company had been using the technique of manually spraying the area with a hose. But Schielein was dissatisfied with the results. “It was an expensive approach, having a worker spend an entire shift spraying the site,” says Schielein. “Even worse was that it was so ineffective. The powerful spray would actually dislodge dust from the ground and send it airborne. And the sheer volume of water quickly soaked the debris, turning it into a muddy mess. If we had to haul any material to a landfill after completing a job, we were actually paying extra for the water weight.” After doing some initial research and comparing equipment from several manufacturers he settled on a DustBoss DB-60, the largest model from Dust Control Technology. “No other manufacturer delivers the quality and durability of the DustBoss,” says Schielein. “Demolition job sites are tough on equipment, and most people don’t realize that dust suppression is a technical issue. The EPA certainly recognizes that there’s more science to it than just blowing water droplets with a fan. All of the components have to be designed to work together, including the fan speeds, blade pitch and atomization nozzles. We liked the fact that Dust Control Technology concentrates only on suppression, and they’re not concerned with
The atomized mist technology has proven so successful for Schielein and his crew that they now include DustBoss literature in the package whenever quoting for a job. selling a wide range of equipment. Dust management is all they do.” IronHustler estimates that the company saves six hours of labour per day during demolition and recycling activities. “The DustBoss started paying back from the first day we used it,” says Schielein. “It’s easy to operate and can run unattended all day, and at today’s pay rates, that can save us as much as $2,000 a week.” Price is always a critical factor when specifying capital equipment, and IronHustler looked at
cheaper alternatives and considered maintenance costs and service life before deciding to purchase the DB-60. “It’s built with all heavy-duty components and carries the best warranty in the industry,” says Schielein. “Our DB-60 has been in service for more than six years, and it’s still performing like new. It’s more than paid for itself in manpower savings, and by helping us avoid work stoppages and potential fines.” IronHustler has since purchased a second DustBoss unit, a DB-30 that’s just the right
size for on-site concrete recycling operations that have become a company specialty. “The smaller unit is perfect for our crushing and recycling,” says Schielein. “This technology has proven so successful for us that we now include DustBoss literature in the package whenever we quote for a job. Customers see that as part of our proposal, and they know we’re employing state-of-the-art dust suppression technology. I wouldn’t use anything else.”

“Internationalisation has always been one of the main objectives of our company. We have sufficient machinery, technology, personnel and production capacity to supply machines all over the world and not just to the domestic market”, says SIMA President Javier Garcia Marina.
SIMA’s Globa Spain is going through one of its worst economic crises. People, companies, and the whole nation are suffer-
Some special analysts in economic trends say that Spain will not reach the bottom until the real estate prices in Spain drop even more. And this situation has particularly hit the Spanish manufacturing industry forcing several to close or reduce employees. But there are companies that are going the other way. Companies that managed to find new ways of doing and increasing business by becoming more flexible in terms of development, manufacturing and sales. A good example is Sima SA in Granada in the south of Spain.

A whole new way of thinking In March the company introduced new products and announced a new way of design, production and customer approach. “Sima and many Spanish companies like us are affected by the recession. It is hard to grow in a climate like this but also challenging to find new ways to succeed. We are now strongly focusing on strengthening our position abroad as the local market in Spain is very weak,” says Sima President Javier Garcia Marina. Since Javier Garcia Marina’s father, Antonio Garcia, founded the company in 1970 it has had continuous growth both inside and outside of the Spanish boarder. In the early years the manufacturing was focused on making machinery for mitre cutting of tiles. Soon after the company was formed

it started on a path of internationalisation, which has been intensified during the last year, forced by the recession and popular products and a strong sales network. Sima is currently selling their produdcts in more than 45 countries within the 5 continents. “Internationalization has always been one of the main objectives of our company. We have sufficient machinery, technology, personnel and production capacity to supply machines all over the world and not just to the domestic market. Therefore, being present in other markets was not an option for us but both a need and an opportunity to continue to grow. From a commercial viewpoint, we have a professional sales force capable of serving all markets. An example of our firm support for the markets is the opening of a new fully owned office in Italy,” says Javier.

Three important objectives Sima has three clear objectives how to grow globally while waiting for the domestic market to recover. The domestic market is no longer the most important for Sima, but Javier believes that it will take at least two more years before there will be any sign of a recovery. The first objective is to increase and strengthen the sales network both by setting up a fully owned sales offices network and production centers. One is already settled and running in Milan, Italy. Another one in Belo Horizonte, Brazil, will be set up this summer. Before the end of the year a production facility will also be start up in Doha, Qatar.

Three new products built with the Mekano principle. From the left to right: Bali, Dakar and Spada.
SIMA also have a wide range of concrete sawing and drilling equipment as well as diamond tools.
The beautiful Morish castle of Alhambra right in the middle of Granada and not very far from the SIMA premices.
Sima has also extended its distributor network to serve new markets, such as the Sub-Saharan region of Africa, South-East Asia, the Middle East and the US. SIMA has also intensified the use of its e-commerce B2B internet site “ClickOnSima” for information, service and products support as well as e-sales. Sima has also intensified the use of the Internet for information, service and support as well as sales. The second objective is a new way of thinking when it comes to the design and production of new masonry saws, which are the core products. Sima has taken a different approach to redesigning the products and changing the production facilities in the plant in Granada. “We have created a whole new way of thinking in terms of our products. Our new range of more competitive products offers greater features and added value for our clients and end users. Our R+D+i department has developed a new concept of products which was launched at SMOPYC, the international trade fair held in Zaragoza, Spain, last April”, says Javier. Most will be aware of Meccano, technical toy that has interested children and adults for many years. Sima has to some extent followed the Meccano idea by creating products that can be easily assembled. “We call it the Mekano range, but it is also similar to the “IKEA philosophy”. Basically we have designed our products to be easily assembled by the end client. The new product idea has been preceded by an extensive engineering and designing work in order to manufacture the products for an easy set up, which also results in just few parts to be assembled by the distributor or end user. Detailed and easy to read manuals are of course shipped with the products,” says Javier. There are several strong arguments for the new products strategy. The products have been made more compact even when fully assembled. They are now more light weighted and when shipped half-assembled some 35% - 45% is saved in shipping space and therefore shipping costs. There are almost no welded joints on the machines as most of the components A group of journalists around the Trencher 60/70.
SIMA’s founder Antonio Garcia and in the background the new chain bench saw Spada. are efficiently engineered and screwed together. Consequently, all of this makes the products within the Mekano range very much price competitive. Each product kit is assembled and quality controlled and the whole of the production is test assembled before being shipped. The new production concept started at Sima started in April. It will take a while to implement the Mekano system and so far the new products Bali, Dakar, Venus and Spada are available with the Mekano idea. But the Sima product range is so much more than the new Mekano range. Sima also has a wide range of traditional masonry saws, floor saws including the new Trencher 60/70 with 2 blades setting for parallel cutting, handheld power cutters, concrete power trowels, core drilling systems, rebar processing machines and finally several series of professional diamond tools and abrasive discs for cutting metal and other type of materials. Sima’s third objective is the company’s implementation and establishing of the trade name on the Internet. Sima aims to become the sector leader and needed to position itself through social networks and direct marketing. To do so, they have designed a new website (www.simasa.com) with access for end users and distributors.
Majority for export Sima, with its 70 employees, has about 65% of its business outside Spain. And they are not going to wait for the Spanish market to recover. Spain is still the number one market but the decision to build up a strong export market was taken many years ago.

Cut it all with the Carbodiam Cobrator The Cobrator Diamond Wire gives flexibility to cut anything anywhere, effectively and profitably. Diamond wire technology is respectful of the surroundings and the environment, allowing working at sensitive sites. The Cobra-
tor Wire offers excellent cutting performance through a wide variety of plain, mixed or heterogeneous materials. The Diamond Wire Technology allows cutting almost unlimited material thicknesses, through nearly all types of concrete, abrasive stone, masonry, steel and cast iron. The flexibility of the Cobrator Diamond Wire makes it possible to carry out unlimited cutting configurations without removing obstructing objects. Examples are offshore rig decommissioning, underwater cuts for bridges and dams and other inaccessible cutting areas. Last but not least Diamond Wire Technology makes it possible to cut at hazardous sites, such as nuclear plant decommissioning and asbestos removal. The Cobrator diamond wire ensures efficient long lasting cutting and reduced operational costs. The strong rubber over springs assembly guarantees excellent reliability, retarding the collapsing limit and maintaining the desired and required flexibility. The watering of the wire is enhanced by the form of the rubber coating that pulls the water along the cut and provides optimum cooling.
Smart devices from K-Max The German company K-Max is amanufacturer of smart devices which makes the contractors work more efficient, safer and smarter. K-Max, located in Mering, has among others a wide range of fastening equipment as well as anchors for easy lifting of for example pre-fabricated concrete blocks.
Fast, fixed and steady with B12 The K-Max B15 makes mounting of machines quick and safe with no use of rawl plugs. The system is patented and perfect for mounting of core drilling machines, wall saws and cable saw rollers to name a few. It works also perfect for fastening of cast plaster and isolation, formworks, angle supports and much more. It is practical to drill a 14 mm hole and screw in the K-Max B12 fasteining device and all is done and safe and sound in place. The B12 provide stability and extremely good fastening with no risk of loosening due to vibrations. Very few tools needs to be used and the device itself can be reused up to 50 times. It has a holding capacity of 3450 kg. Standard lengths are 230/280 mm and for cast plaster 300 mm. Special lengths are also available.
The B12 is produced in a special high grade alloy.
K-Max water retension ring WSR 150 and WSR 250 are K-Max system for taking care of the water and slurry when core drilling. The system saves time and gives no contamination at the jobsite. The mounting is carried out by using a negative pressure created by the device and by using wet or dry vacuum cleaners. The system also protects the operator from slurry and debris.
Pre-screener extractor K-Max also offers a smart method for vacuuming liquids. The device can be used with any type of commercial wet or dry vacuums. Liquids are directly transfered from the pre-screener using an integrated immersion pump. The system protects the vcuum cleaners so no liquitds can reach the vauum. This means also that there will be no contamination of the filter. The device is to be launched early 2012.
The high strength vulcanized rubber offers an extremely strong bonding of the beads on the carrier steel cable protecting the cable against the sharp corners, reinforcing bars, cutting dust, abrasion and corrosion. The rubber compound also protects the wire against insufficient cooling. The improved wire flexibility ensures an even wear of the diamond beads for maximum cutting effectiveness and improved performance on all types of cuts. The Cobrator diamond wire respects the environment by minimizing noise, debris creation, and dust pollution. Vibrations are practically eliminated so that the structural integrity of the surrounding structures is maintained. This protects the health of operators, neighbours, and passersby.
New PCD scraper series from Ashine Chinese manufacturer Ashine Diamond Tools is now launching a series of so called PCD scrapers. According to Ashine this is the contractors’ best choice in terms of removing heavy coating on concrete floors. Each tool has a lifetime of 2000 m2. The applications the series are developed for are to remove all types of stubborn coatings, such as paint, varnish, glue, epoxy, acrylic, screed residue, VCT mastic, black tar, adhesive as well as thick rubbery material. The advantages are among others the high efficiency during heavy works. The tool is aggressive even met with concrete during epoxy removing jobs and PCD still hold very tightly. A representative for Ashine says that the clients comment over the Ashine PCD scraper’s performance is similar to several other large brands on the market but with much lower price. The tool series are developed for walkbehind floor machines. According to Ashine the tools design can be changed for different machine like HTC, Blastrac, Werkmaster and Terrco to name a few.

It can be used as the second or third member on a carrier, depending on the carrier size,” said Indeco marketing manager Michele Vitulano. Features include a dual profile piercing tip system, with differentiated upper and lower tips designed for a clean and gradual cut. The four steel knives are all the same length and are reversible and interchangeable, so that all four cutting edges can be used. A heavy-duty pivot group is designed to provide long-term cutting efficiency, keeping the jaws aligned and
According to data from the Committee for European Construction Equipment the recovery, in short, is already a reality in some countries, such as Germany, France and Great Britain, while others, such as Italy, present a stagnant market, or are still suffering setbacks, as in Spain. “It is not the same Samoter as three years ago, but something is moving in the right direction while good business is right now outside of Europe. Right now we are walking in small steps and hopefully business will be back to full speed in one or two years,” said Mario Passeri, owner of the Italian dust suppression equipment manufacturer WLP in Trento.

But in 1961 they founded Armofer Cinerari Luigi,” said Armofer communication manager Federica Delucchi. “All was very manual and dangerous work since the very beginning up until the 1970-1980’s. Therefore the brothers became very engaged in safety issues in the demolition industry from a very early stage.” The whole history and development of the family company has been thoroughly documented in the book Professionisti delle demolizioni 1961–2011 presented at the Samoter fair.

est hammer in its hammer range the H25D. The simplified design of the D-Series small hammers ensures a lower owning and operating cost and improved serviceability. The single bushing design combines three bushings into one for a slip fit that is field replaceable. The H25D model has ultra high blow rates to enhance greater productivity in concrete and asphalt applications. Caterpillar Work Tools also showcased the new Cat S365C mobile shear, which features a bolt-on piercing tip for thorough protection in critical wear areas, easy maintenance for optimal piercing performance, and field serviceability without welding. The shear also features structural changes for extended durability. The Cat bolt-on piercing tip design offers several advantages. The tip protects the moving jaw on both sides, effectively protecting the parent metal from wear as the moving jaw travels through the lower jaw. Additionally, the tip blades are fully reversible so that each blade provides two uses. Common hand tools are all that is needed to reverse the blades, and the tip can be maintained without moving the knives in the jaw. The result is faster and easier maintenance. The Cat tip also uses identical parts for both sides of the jaw.

What is absolutely clear now is that there will be no BeBoSa in the same year as Bauma. It may prove a wise decision, since the world’s biggest exhibition tends to overshadow its smaller local counterparts. Having the next BeBoSa in a place a bit more accessible than Willingen may be another good idea. As the show’s potential clearly transcends the boundaries of Germany, international visitors will surely appreciate a more metropolitan location.

Bridge cutting with Skystone diamond wires.
A specialist wire man Fuzhou-based Skystone Diamond Tools has been manufacturing diamond consumables since 1994. In 2000, after six years of sustainable development, the company chose diamond wires as its mainstay product and began to specialize in this business. 76
Diamond wire is the most challenging product of the entire diamond tool spectrum in terms of manufacturing complexity. There are many factors at play: the composition and shape of diamond beads, the precision of rubber vulcanization process, the resiliency and durability of inner metal cables. If any of the numerous process requirements is not met, the diamond wire (and the contractor’s time and money) is as good as wasted. It takes time and effort to fully master the art of diamond wire production, so every manufacturer known to make a good wire is treasured by professional contractors.
Specialization is the key There are not too many manufacturers in the diamond tool business that favour specialization over diversification. Most of the players in this market tend to produce a wide range of diamond consumables – from polishing pads and grinding wheels to drill segments to all sorts of blades and wires. Under these conditions, achieving perfection for every item in one’s catalogue is highly unlikely. Skystone is one of the precious few that have chosen a different path and focused on one business – in their case, wire sawing. The company began to research into this field in 2000 and after three years of hard work it delivered its first diamond wire for granite cutting under the brand name of Skystone. By 2011, Skystone has evolved into one of China’s biggest manufacturers, with a staff of 250 and a product range of 34 specifications. The company is now able to offer 23 different types of diamond wires for cutting any construction material – from reinforced concrete with varying degree of steel reinforcement (including a few specs for
PDi • Issue 2 • May - June 2011
underwater wire sawing) to straight steel and masonry – plus 11 specs for quarrying jobs. Skystone’s bestselling construction specs are TSY-SRC110 and TSY-SRC114 – rubber-coated wires with sintered beads for cutting concrete with 3–5 percent steel reinforcement. The GQR114 for granite cutting is the most Skystone’s wire saws at work.
popular wire with quarrying companies.
Backing it up with hardware Interestingly enough, Skystone builds its own wire sawing machines, too. The machines are primarily designed to work in quarries, but Skystone’s 15kw wire saw, for instance, is wellsuited to concrete applications as well. Skystone runs two plants in the Fuzhou area – one produces 300,000 meters of diamond wires a year, while the annual capacity of its hardware factory is some 300 machines. Each plant has its own R & D centre to keep up with the fast-paced manufacturing industry. On top of that, Skystone has set up two “project management centres” that are a sort of a task force investigating various demolition and construction projects.
Underwater wire sawing operation.
Global reach Skystone has been pursuing a very active export policy by supplying its diamond wires into more than 30 countries. The company’s reach now extends as far as the USA, Australia, Brazil and Russia. At the moment, Skystone is zooming in on the European market, with Germany being the most desirable target. Toward this end, the company has made sure it will attend Stone-Tec, an important event in the stone industry, which is going to be held in Nurnberg this June. The manufacturer will use this exhibition to showcase the bestselling models TSYSRC110 & TSY-SRC114 as well as its stone-processing range to the German audiences. In the fall, Skystone will fly over to Italy to take part in Verona Stone Fair and SAIE. And it goes without saying that Skystone tools and machines are on display at every Bauma and World of Concrete show.

The Danish demolition contractor Tscherning AS was part of the presentation of a demolition project at the EDA Autumn Conference 2010 in Sweden. During discussion after the panel debate, Tscherning executives were encouraged to present their international certifications according to ISO 9001, ISO 14001 and OHSAS 18001. On the following two pages there is a brief description of the Tscherning management system, its creation and its implementation.
Tscherning gained strong advan new management system and c By Klaus Bodilsen and Tue Brix, G. Tscherning A/S, Denmark Photos: G. Tscherning A/S

The Tscherning management system handles quality, environmental and occupational health and safety issues. It has held the triple certification since 2003. With a wide range of business activities and daily, on-site interfaces with other contractors in the building industry, it was decided to develop an integrated management system, mandatory for all business areas and all company processes. The system is based on the Management Policy and is centred on the system manual and its enclosures accessible on-line.
PDi • Issue 2 • May - June 20111
Management system creation Wanting the system to become deeply rooted with the company’s staff and wishing benefits as early as possible it was decided to create the system manual and its enclosures simultaneously. The system was promoted and implemented according to its progress. For full integration of system elements Tscherning decided their own system structure. Their own analysis of existing material, company procedures and the actual stage
During the system development, visibility of the process and promotion towards employees was a major part of their work. The system development was, at relevant points, discussed with staff and employees and incoming reactions and suggestions were carefully examined. As a light and slim system was crucial to Tscherning, the creation of system enclosures was kept very strict and all enclosures were developed to fulfil more than one purpose.
Implementation Implementation of the Tscherning management system began immediately after the development of the first system elements. A Foreman’s Forum was established and was, together with the statutory company Safety Organization, a good place for internal discussions of the system development stage and of daily experiences with its use. “Very soon we saw major improvements. In particular regarding occupational health and safety issues. The important and obvious improvements were a great encouragement to carry through the more administrative system elements,” says Klaus Bodilsen at Tscherning.. On staff and management level the system mainly required creation of fixed procedures and an improved documentation effort. Implementation was therefore joined by the first internal audits, initially targeted towards user facilitation and education, rather than reporting of non-conformities. We strengthened the efforts for planning and execution of site jobs and began formalized education of staff and employees. Towards the employees, targets primarily were to achieve regular use of all prescribed protective equipment, understanding of the company policy and creation of awareness towards the system use. Company goals were communicated, and site performance was audited with an internally developed method. Employee qualifications were registered, and a training programme was decided to meet the discovered or the newly fixed requirements.
Certification
ntages with certification of quality, environmental and occupational health management resulted in an outline with chapters organized in five sections, offering a process based approach to the system. The creation was initiated in 2001. For all chapters, Tue Brix authored procedures meeting external and internal requirements. Aspects were evaluated with Project Manager Klaus Bodilsen and Managing Director Søren Tscherning, leading to changes in current methods, establishing of new ones and or to adaption of the outline.
Certification of the Tscherning Management System was carried out by BVQI (now Bureau Veritas Certification, BVC). An initial system review lead to a pre-audit visit, indicating points to be strengthened. After a few adjustments to the system, four BVC auditors reviewed performance and conformity with system and requirements during a two-day certification audit. “In May 2003, we received four certificates (one of them national), hence becoming the first Danish company to achieve a triple, international certification with a newly created, integrated management system. Each certificate is valid for three years, and system conformity, use of procedures and a due amount of documentation is audited by BVC every six months. Every three years, certificates are renewed after a certification audit,” says a satisfied Tue Brix.
Results G. Tscherning A/S have obtained several advantages with the system implementation and in the creation process. An effort to improve the company overall was initiated and especially the safety gain is crucial. Improved, general quality awareness and a desire to meet customer demands have emerged, and internal communication has been improved. As a spin-off, a company design line was decided and employee’s clothing was changed. Tscherning have also experienced commercial benefits, both in regard of publicity, improved effectiveness and in facilitating prequalification processes and tendering. Their fixed procedures result in a more predictable performance, improving planning and decreasing the number of mishaps. The creation of the Tscherning management system and the certification has proven to be a great advantage and the system is an effective platform for the on-going process of company and site management.

The CS 1225 H includes a tool to hose adapter to easily connect portable power tools such as concrete grinders or saws for dust removal while the tool is in operation. A “Power Take Off” outlet activates the vacuum ON/ OFF from the power tool switch and includes a 10-second shutoff delay to clean any dust left in the hose. An automatic shut-off sensor protects the motor and filters during wet vacuuming. Its Electromagnetic Pulse Filter Cleaning System shakes the HEPA filters to remove dust, maximizing suction and doubling filter life. The vacuum senses when the filters are clogged and the suction power or air flow is restricted, cleaning itself when the vacuum is turned on and again when it is turned off. This feature can be set to activate automatically or manually. A 15’ hose and 25’ power cord make the CS 1225 H ideal for most construction jobs. Weighing less than 25 pounds, it is portable and very convenient to use on the job site or in the shop. A cleaning kit, including wands, nozzles and hose is also available.

CSDA Elects 2011 Board and Officers In the US the Concrete Sawing and Drilling Association has announced the 2011 Board members who were elected at the 39th Annual CSDA Convention and Tech Fair, held on 10-12 March, 2011 in Bonita Springs, Florida. Six Board members, whose terms expire in 2013, were elected. They are Roger Allen, Diamond Tools Technology, Buffalo Grove, Illinois; Ty Conner, Austin Enterprise, Bakersfield, California; Mike Greene, Greene’s, Inc., Woods Cross, Utah; Larry Liddle, Diamond Products, Elyria, Ohio; Kellie Vazquez, Holes Incorporated, Houston, Texas and Kevin Warnecke, ICS, Blount Inc., Portland, Oregon.

“I’m really happy to have been re-elected to serve a second term as a member of the CSDA Board of Directors,” said Kellie Vazquez. “This is a great opportunity to work with my peers and continue to advance and shape the industry in which we work. I am also part of the CSDA Next Generation group, and so I will be working hard to get more younger concrete cutters involved in the association’s committees and events.” The CSDA Officers were also present at the event. Jim Dvoratchek, Hard Rock Concrete Cutters, Wheeling, Illinois, returns for his second stint as CSDA President, having last held the position in 1999-2000. Judith O’Day, Terra Diamond Industrial, Salt Lake City, Utah now serves as Vice President while Mike Orzechowski, DITEQ Corporation, Lee’s Summit, Missouri, takes up the role of Secretary/Treasurer. Doug Walker, Atlantic Concrete Cutting, Inc., Mount Holly, New Jersey, serves as Past President and Patrick O’Brien continues to serve as Executive Director.
CSDA Convention Attendance Up 30%
sparked much interest from attendees, and led to sales. First-time Tech Fair exhibitor Markus Bartl of Expert Equipment Company in Houston, Texas, was pleased with the event. “It turned out to be a very successful exhibition, as I was able to connect with many leading professionals in the industry from all over the country. What surprised me was the friendly and cordial relationship between exhibitors—even among direct competitors. More importantly, however, I took orders.” The CSDA Lifetime Achievement Award was presented to Past President Ron Van Zee of Diamond Concrete Sawing, Grand Rapids, Michigan, for his outstanding contribution to the association and the industry as a whole. Incoming CSDA President, Jim Dvoratchek of Hard Rock Concrete Cutters, Inc., Wheeling, Illinois was welcomed as the new president at the event, and an award was given to outgoing president, Doug Walker of Atlantic Concrete Cutting, Inc., Mount Holly, New Jersey, for his service to the association. Outgoing members of the CSDA Board of Directors were also recognized. The members and staff of CSDA will now turn their attention to planning for the 2012 Convention in Maui, Hawaii, which will mark the association’s 40th anniversary and is expected to draw an even bigger crowd than the 2011 event. Next year’s convention is scheduled for 7-9 March, 2012 at the Sheraton Maui.
Attendance rose 30% from last year’s convention as contractors and manufacturers from the concrete sawing and drilling industry gathered in Bonita Springs, Florida from 8 - 12 March for the 39th Annual Concrete Sawing and Drilling Association (CSDA) Convention and Tech Fair. Included in the large number of attendees were new members, first-time attendees and many Past Presidents of the association. This diverse group made for much sharing of information, exchanging of ideas and networking. A keynote presentation was given by Clint Longenecker, Ph.D., entitled The Two-Minute Drill, a leadership practice based on American football. Longenecker’s presentation was well received and some CSDA members are already taking steps to implement The Two-Minute Drill into their businesses. “I was so inspired by the seminar that I could not wait to get back to the office and utilize some of the tools that were provided. I learned that it is important to have solid leadership, a solid plan and consistent follow-through in order for any change to work,” says Paul DeAndrea of DeAndrea Coring & Sawing, Inc. in Henderson, Colorado. Concrete cutters, and manufacturers who supply contractors with diamond tools, came looking for ways to improve and grow their businesses as signs of an economic recovery begin to appear. The number of exhibitors at the CSDA Tech Fair also increased from 2010, with 24% more companies on hand to meet one-onone with contractors in a more intimate and informal manner than large trade shows.

Certification Provides Companies with a Cutting Edge Concrete Sawing and Drilling Association (CSDA) member Cutting
The CORR programme is a national third-party certification programme designed to verify building materials debris reuse and recycling rates by construction and demolition (C&D) reuse and recycling facilities operating in the USA. The CORR certification standards were developed by the Construction Materials Recycling Association (CMRA) and a stakeholder group involving environmental non-profits, architects, academia, government agencies and the recycling industry. The CORR will provide the C&D reuse and recycling industry with a means to communicate their management of construction-related materials debris to the general public and the construction industry. It will provide confidence to the general public and the construction industry of the reuse and recycling rates reported by C&D reuse and recycling facilities. The goals of the certification program include: • Provide a procedure for accurately accounting for the materials inputs and outputs of a C&D reuse or recycling facility. • To provide an objective and transparent process for eligible firms seeking to communicate their reuse and recycling of C&D materials. • To provide users of certified facilities an assurance that the procedures and reuse and recycling declarations are consistently applied and verified. The certification begins with an application by the firm, and either the qualification of procedures in place, or establishing the procedures required to measure and report the facility’s materials flow. The certification process includes site visit(s) and the verification by a third-party certification entity of the quantities and types of reused or recycled materials produced by the facility on a monthly and annual basis. Outputs are classified as: • Reuse • Recycle • Bio-Fuel • Alternative Daily Cover • Disposal
NSWMA/CMRA announce construction and demolition wood fuel specifications The Construction Materials Recycling Association (CMRA) and the National Solid Wastes Management Association (NSWMA), worked together to develop viable, in-use construction and demolition (C&D) wood fuel specifications. The specifications are based on industry experience, permit requirements for boilers using C&D wood as a fuel stock and regulatory requirements governing the use of this material. The specifications provide real world guidance on what works in the marketplace for C&D wood fuel buyers (boiler owners and operators) and sellers (C&D wood processors). C&D wood is generated at construction and demolition sites and processed throughout the U.S. by dedicated C&D processors. The processed wood is turned into a variety of end products, one of the most valuable of which is a fuel stock.
