PANORAMACANADAAir power for CanadianQuarryFormed at the beginning of the year, Forexplo hasquickly established itself as a drill and blastspecialist in Canada’s Quebec Province, winning areputation for meeting clean and efficient productiontargets, on-schedule and within budget. Thecompany is using Atlas Copco XRVS 1000 CD6 aircompressors to power two 750 hp drill rigs.Jointly formed by Mr. Bilodeau and Mr. Vachon earlier this year,it followed many years experience by both men operating for othercontractors.Quickly winning its first drill and blast contract with Beauval forall their quarries - the first one in Valleyfield, Qc 40 km west ofMontreal and the site Ange Gardien, some 55 km south ofMontreal and near to the Appalachian mountain range. A thirdaward was soon to follow at Herbertville on Lac St Jean. Andalready the company is confident it is set to be awarded two furthercontracts.Having always used American-brand compressors in the past,Mr. Bilodeau and Mr. Vachon were impressed with the fuelconsumption promised by Atlas Copco. The XRVS 1000, ratedwith a free air delivery of 1000 cfm at 25 bar (365 psi) is powered by a Caterpillar C13 ACERT T3 diesel engine andAtlas Copco FuelExpert to provide fuel consumption figures of just 60-62 l/h.“This exceptional figure compares with the 90 l/h from our previous American compressors,” said Robert Bilodeau,adding, “Over a year this represents a significant cost saving.”The Ange Gardien quarry was first established in the 1960s and was acquired by Beauval in 1981 to offer a broaderdiversity of crushed stone comprised mainly micritic limestone and slate and serves the Monteregie and Easterntownships.With reserves for at least another 25 years, the quarry rock features micritic limestone and a black argillaceous slate.Featuring three bench levels along the l km long quarry, Forexplo are drilling and blasting 8-12 m deep bench heights.Depending on Beauval’s requirements, Forexplo are typically drilling 56 holes for a blast to provide approximately20,000 t. Using Atlas Copco standard or Speedbit 140 mm diameter drill bits and hammer, Forexplo is drilling up to 30m/h.“Use of the speedbit in the harder rock ensures a 10% faster production rate,” said rig operator, Guy Gouthier, “This,together with the Atlas Copco compressor giving me air power on demand, makes a great combination.”Atlas Copco Airpower nvITALYCompact loader for tunnellingprojectA Bobcat T300 compact tracked loader has provided a unique, costeffectivesolution for removing spoil in the construction of a pedestriantunnel at the site of the 14th century monastery of Santa Caterina delSasso. This is a popular destination for pilgrims and is located at thebase of a sheer cliff face above one of the deepest points on theeastern shore of Lake Maggiore in Italy.Linked to a new 12-person lift system taking visitors down from thecar park, the tunnel will make it easier for everyone to visit themonastery, particularly the elderly and disabled, access for whom wasseverely hindered by the steep steps that were previously the only waydown the 50 metres from the car park to the entrance to the monastery.Page 6

PANORAMAThe works were commissioned by the Architectural Heritage Sector of the Province of Varese, with the collaborationof the Achille Balossi Restelli Engineering Company in Milan. As early as the planning stage, it was clear that removingspoil from the tunnel would severely restrict the progress of the work. The inaccessible entrance, little room tomaneouvre and the need to lower a machine to a specific point using only the construction site crane narrowed thechoice down to a compact loader, as no other type of machine would have been able to work in these conditions.The contractors opted for a Bobcat T300 compact tracked loader, fitted with an anti-particulate filter by Bobcat dealerMAIE to reduce emissions in the tunnel. Together with a range of attachments, the T300 loader was purchased bySondrio-based ACCISA SpA, a specialist in this type of excavation work which acted as subcontractor to I.CO.P. SpA,the main contractor on the project, based in Udine.Massimiliano Duca of ACCISA, said: “We were looking for a compact loader which could remove spoil as quickly aspossible. The machine had to be powerful and have lifting capacities suitable for working in difficult conditions. Weightwas another problem: we had to partially disassemble the loader and lower the components to the tunnel entrance witha crane which had a maximum capacity of 1.6 tonne. With the assistance of MAIE, the loader was disassembled so thatthe largest and heaviest assembly, the main chassis, could be safely lifted by the crane. The machine was thenreassembled at the tunnel entrance to carry out the work and, at the end of the job, it was again disassembled toremove it from site.”BobcatUSACapital job forComansaOne Comansa 21 LC 400 towercrane works on the restoration ofthis historical building at a height ofalmost 104 meters (340 ft)JE Dunn Construction Company,the twelfth largest generalbuilding contractor in the UnitedStates, is managing the KansasStatehouse Exterior MasonryRestoration project, in Topeka,capital city of the state.This $36 million project, whichwill take 4 years, is a big challengedemanding good material hoistingaccess to all sides of the drum thatsupports the dome.The Capitol’s cruciform floorplan, the presence of otherstructures of the complex aroundthe building, an aggressive working schedule and the expenses of requiring multiple crawler cranes were optionsconsidered by the managers.The final solution was a single 21 LC 400 tower crane. It was erected with a height under hook of 103.8 meters (340ft), and a jib length of 80 m (262 ft), allowing the operator to reach every spot of the jobsite, and to move the jib over thestatue -a Native American archer from the Kansa tribe - that tops the dome at a height of 93 m (304 ft).To achieve this height without tying the crane to any other structure, a special tower configuration was designed: nine4 m wide sections (13 ft), one transition section, and other nine 2.5 m wide sections (8 ft).Blake Graham, project manager with JE Dunn, has said that it is currently the tallest freestanding tower crane inNorth America.Since the beginning of September, the crane, with 18 tonnes (39,683 lb) of maximum load and Flat-Top design, hasbeen at work transporting materials required for the restoration around the perimeter of the dome. The exterior masonryproject includes stone stabilization, crack repair, dutchman repairs, hand carving and others.ComansaContractors World Vol 1 No 9Page 7

PANORAMAUSAManitowoc 18000 critical tobridge replacement projectA Manitowoc 18000 is working on a bridge replacementproject in Pennsylvania. The project involves completelyreplacing the Pohopoco Creek and Lehigh River Bridgestructures on the Northeast Extension of I-476 in USA.During the course of the project, 175 beams measuring 31m (102 ft) to 51.2 m (168 ft) and weighing up to 109 t., willbe placed by the 18000.Aaron Barnes, assistant resident engineer for the LehighRiver and Pohopoco Creek Bridge Replacement Project,said access and logistics made beam erection a realchallenge on this project.“We installed a construction causeway, where themajority of the picks are made, in the Pohopoco Creekvalley,” he said “Extremely steep slopes border the creek onboth sides, and there is limited space on the causeway thatruled out picking the beams with two cranes. Because ofthese factors, we needed a crane that can lift beams of over90 tonnes at a radius of 36 m (118 ft) — the Manitowoc18000 fits the bill perfectly.”The most challenging aspect of the job was the erectionof beams for the longest spans on the Pohopoco Creek structures. There was very limited site access, so liftingcontractor Cornell and Co. had to pick the beams from the right lane of the southbound mainline turnpike. Traffic laneswere closed while the 18000 set up on the construction causeway 36.5 m (120 ft) below the beam.Except for the northernmost spans of the Pohopoco Bridge, the crane is picking the beams without assistance. Thepicks have to be done so the crane is close enough to handle the weight of the beam, but far enough away so thelongest beam — 60 m (164 ft) — clears the crane’s boom.The crane, which is owned by ALL Erection and Crane Rental, will have several different configurations during itstime on the project, but for its most challenging portion, the 18000 worked with 30.5 m (100 ft) of mast, 48.75 m (160 ft)of main boom and a 39.5 m (130 ft) luffing jib. It had 240,000 kg (528,000 lbs) of crane upper counterweight and145,000 (320,000 lbs) of carbody counterweight.The bridge replacement project began in January 2009 and is expected to be open to traffic in November 2011.CHINABig, heavy lift for SANYcrane at nuclear facilityA Sany SCC10000 - a 1000-t-class crawler crane -was used to successfully place the core part ofproject- the dome of Fuqing nuclear power station inFujian, China.The dome of the nuclear power station is 11 m inheight, 37 m in diameter and has a total weight of170 tons. For this assignment, the crawler cranewas configured with 60 m main boom, 54 m luffingjib, superlift mast and superlift. This enabled aworking radius of 24 m, while the angle of the mainboom was 75.1° and its hoisting height was 60 m.The maximal rated hoisting load of SCC10000 is1000 tons and its rated lifting moment can reach14,000 t/m. The crane can be configured to reach96 m + 96 m, and the maximal vertical lifting height was approximately 190 m.ManitowocSanyPage 8 Contractors World Vol 1 No 9

PANORAMABELGIUMDoosan Generator Powers GiantAntwerp DiverAt the Antwerp Festival in Belgium, power from a Doosan G30generator supplied by Hertz Equipment played an important partin a breathtaking performance of giant mechanical marionettescreated by the world famous French street theatre company,Royal de Luxe.Entitled ‘The Diver, his hand and the Little Giantess’, thespectacular event in Antwerp took place over three days duringthe Festival and was a reworking of Royal de Luxe’s ‘The LittleGiantess of the Titanic and the Diver’, performed for the first timein the company’s home city of Nantes last year. The story wasgiven an Antwerp context and a new title that referred both to theorigin of the Antwerp name which means ‘Throwing hands’ inEnglish and also the city’s legend of the Giant Antigoon andBrabo.Founded in 1979 by Director, Jean Luc Courcoult, Royal deLuxe has staged thrilling events all around the world from placesas far apart as England, Germany and Iceland to Chile andAustralia. Played out in the streets, often in city centres, theevents are always free and open to anyone to watch.In Antwerp, the company is well loved for the previousproductions of ’The Big Giant and The Little Giant’ in 1998 andespecially ‘The Elephant’ in 2006. Like these, ‘The Diver, hishand and the Little Giantess’ featured giant figures which arrivedin the city and went about their business for the three days of theevent. As the performances took place, huge crowds gathered daily to watch the latest episode in the life of the visitors.The first of the giant figures was the Diver which, with its transport system (a modified dragline excavator with anadditional crane arm and cable structure) stood 15 m tall. The Doosan G30 generator was mounted on the transportsystem and provided power for electrical controls on the puppet, including the streetlamp lights that form his eyes andare moved by small motors. The Diver marionette itself was 9.5 m high, 2.8 m wide and weighed 2.5 tonne. Operatedby 30 puppeteers, the Diver had a body made of steel, lime wood and poplar wood, hair made of horsehair andeyelashes made of broom hair.Following the Diver was the Little Giantess mounted on a modified agricultural machine together weighing 13.5 tonneand standing 7.5 m high. Twenty-two people were needed tomove the Little Giantess.The performance also featured the Boat mounted on alorry and trailer. Operated by 6 people, the Boat can pitchbackwards and forwards and rock from side to side, as if in astorm. It was placed in a 12 m x 3 m basin filled with waterand had a gigantic fan fixed at its prow to simulate differentwind strengths.Hertz is one of the leading rental companies in France andthe company’s hire fleet available from an extended networkof outlets, includes over 100 generators purchased fromDoosan Infracore Portable Power (DIPP), ranging from theG20 to the G500 model.These models and the G30 are part of the PowerSourcegenerator family from DIPP, which comprises 12 mobile andportable generator models with prime power outputs at ratedspeed from 10 to 500 kVA and designed to offer an optimummix of performance, fuel economy and low emissions.DoosanPage 10 Contractors World Vol 1 No 9

SWITZERLANDTunnel to extend the SwissAlpTransit lineBesides the works of the renowned Gotthard Base Tunnel in Switzerland, part of the Swiss AlpTransit line, this springwork also started on initial drill and blast of another important tunnel: the 15.4 km long Ceneri Base Tunnel in the cantonof Ticino from the north portal near Camorino, the south portal at Vezia and in the installations cavern of the intermediateheading at Sigirino.This tunnel, with two single-track bores, continues the Swiss AlpTransit line south of the Gotthard Base Tunnel andis, like Gotthard, built under contract from the Swiss Federal Government by Alptransit Gotthard AG.The commercial operation of the Ceneri Base Tunnel is planned to start at the end of 2019. Upon its completion it willallow high-speed rail and heavy freight trains, both of which were not possible in the existing steep track over themountain of Monte Ceneri.Tunnelling on the main 2.3 km long access adit to the cavern already started in 2008, using a 9.7 m diameterRobbins TBM. The construction site for the two railway tunnels will be in full swing in autumn 2010. Excavation, supportand lining work should be finished in 2016.The tunnel contractor consortium Condotte Cossi had a long hard look at several manufactures who were bidding forthe lucrative machinery order. They opted for the Swiss Cat dealer Avesco who was able to offer most of the requiredmachines to complete the excavation of the twin tunnels.For the Ceneri Base Tunnel Project Avesco, Italian Cat dealer CGT and Zeppelin, the Cat dealer from Germany, areworking together. Another plus for Avesco was the experience they gained with supplying and maintaining equipment forthe Sedrun section of the Gotthard Base Tunnel.As the “Bautechnik” branch ofAvesco is the official dealer forSandvik, they were able to offer acomplete package including eightdrilling jumbos, four undergroundwheel loaders, eight compact radiustunnelling excavators, eight hydraulichammers, eight special wheel loadersand some support equipment.The Cat 314D LCR and 328D LCRexcavators, customized by the dealerfor tunnelling purposes, are a rarespecies among the large CatCat machines had to be reconfigured bythe dealer to meet the operatingconditions in the tunnels.Contractors World Vol 1 No 9Page 11

unconventional in shape andsize. A further feature on bothexcavators is the heavy-dutydozer blade fitted to the carbody.Strong covers protect the topside of the blade cylinders. Itensures outstanding stability andalso enables any levelling workto be undertaken.While clearing the tunnelcrown and vertical face fromloose rock, the blade at the rearprevents the machine fromcreeping backwards.Like every other machine thatworks on the Ceneri tunnellingsite, the eight compact radiusexcavators are equipped withtwo fire extinguishers, one in thecab and one on the outside of the excavator.To change a standard Cat compact radius 314D LCR into a 15.5 tonne tunnelling excavator, Avesco invested a lot ofman-hours. Obvious is the short main boom. The mechanics removed the original 4.65 m long booms and the weldersbuilt new 2.01 m long ultra short booms. Except for the strong cylinder cover, the stick and the hydraulic quick couplerare standard.Besides the ripping claw, a 1330 kg Sandvik BR2266 hydraulic hammer and a standard backhoe bucket for loadingpurposes can be attached to the quick coupler.With an operating weight of 43.5 t the Cat 328D LCR is so far the only short radius tunnelling excavator in the 40 tclass. The tail swing radius of just 1.90 m only marginally protrudes over the undercarriage. The 328D LCR shares theupper-structure of the 329D and the undercarriage of the 336D.Its specially designed boom with torsion resistant cross-sections is built by the German Cat dealer Zeppelin. Themain boom of the 328D LCR pivots 45º to the left or right of centre. This tilting mechanism allows the excavator to reachmaximum operational flexibility in narrow tunnel profiles. The bucket stick is 4.65 m long and can be equipped with allkinds of buckets, hammers and drum cutters.Avesco delivered four 2370 kg Sandvik BR3088 hydraulic breakers for the Cat 328D LCR tunnelling excavators.For the loading and shovelling duties within the narrow connecting galleries between the two single-track tunnels,Avesco modified four Cat 938H wheel loaders. To make them tunnelling proof, the mechanics shortened the fenders oneach side and removed parts of the rear fenders. The maximum width of the loader is now 2.6 m. To better protect theoperator from falling rocks, a Falling Object Guarding System (FOGS) was added to the cab and a front windshieldguarding.A moving cover prevents damage to the dump-cylinder and heavy steel beams on the counterweight protect theradiator from side-impacts. The side dumping buckets were built up to specifications by the Swiss based attachmentspecialist Ullmann.Like every other Cat machine that works on this tunnelling site, the engine of the 938H wheel loader is equipped witha diesel particle filter and with a ”Fogmaker” fire extinguishing system. In case of an emergency the operator can alsomanually activate the system.Every operator has a sticker on the back of hishelmet which shows that he has received the propertraining from Avesco and is authorized to operate theindicated piece of machinery.When the drill and blast operation is at full swing,the crew of the intermediate heading at Sigirino willdrive the two tunnels simultaneous to the north andsouth.CaterpillarSandvikPage 12 Contractors World Vol 1 No 9

20 minutes with:Roger Lindley interviewsDavid Beattenbough.LiuGong - Vice President Research &Development“David, thank you for your time. I have seen the increasing awareness of LiuGong over recent years attrade events, etc. and had the opportunity to meet with you at Bauma 2010. As we approach the end of adifficult year for many, it may be a good opportunity to look anew at some of the issues we discussed.There is no disputing the size and strength of LiuGong as a manufacturer of construction equipment, butif we extract the domestic Chinese market from unit sales, then, as a global player, LiuGong is makingprogress but still has a long way to go. How is the company going to do this - by developing overseasmanufacturing facilities; by forming strategic alliances; through a dealer network or direct selling throughregional offices?”“Customer support has to be the basis for any plan to increase LiuGong’s strength internationally. Even ifwe have the best products in the world we cannot be successful unless our customers can get the supportthey need. Our strategy for distribution is built around this philosophy. We have currently 5 subsidiarycompanies and 6 parts depots around the world.When LiuGong decides to enter a market, we put the required infrastructure in place to support dealersbefore we sign dealer contracts. This ensures that when customers buy LiuGong products they receive,from the very first day, the quality support for their purchase they deserve, and that customers around theworld have come to expect from LiuGong. LiuGong believes very much in the value quality dealers bring tothe organization, so we will always grow internationally by strengthening our dealer organization, and wewill always sell only through our dealer organization.LiuGong has an obligation to our customers to provide high quality construction equipment at the lowestpossible cost, and in the shortest time possible. This will require us at times to produce in other countries.In 2009 we opened a factory in India, and other manufacturing facilities will follow around the world aseconomic conditions dictate.”“Historically, Chinese products have been seen as low cost, poor build quality. Unreliable and notsupported at local level. Given that plant buyers, being conscious of the current economic situation, wantequipment that is not only affordable but is also reliable, highly productive and with an assured parts andafter-sales service. What is LiuGong’s response to this requirement?”“A good example of our parts and support commitment is ourapproach in Western Europe. LiuGong set up LiuGong Europe,a parts, sales support, and service subsidiary company earlythis year. We initially stocked the parts warehouse withmore than 1 million Euro of spare parts, and thestocking level is growing continually. Only after wecompleted these important steps did we startprospecting for dealers.For the basic quality of our products, we only have tolook at the typical duty cycle a LiuGong machine will seein its normal life in China. 5000 hours per year, or evenmore, is very common for LiuGong machines in China. Whenwe export machines capable of this duty cycle to other markets whereannual usage is not as high, it is almost like we are sending our machineson holiday.Of course, quality is not only about the duty cycle, but a way ofthinking that starts in design, and is carried through manufacturing, andLiuGong ZL50CX3m³ wheel loaderContractors World Vol 1 No 9Page 13

LiuGong first Chinese manufacturer tobuild a complete plant outside of China- in India in 2009.on to the customer. LiuGong usesadvanced R&D techniques such asQuality by Design, Design forManufacture, Failure Modes andEffect Analysis, and many otherprocesses to guide our productdevelopment. LiuGong also isinvesting a lot into Six Sigma, andof course we are ISO 9000 and14000 certified.”“LiuGong doubled profit in 2009 at atime when other OEMs where strugglingto stay in profit. Is this purely the result of the buoyant Chinese market or did the company take othermeasures to ensure it maintained a high level of profitability? Extrapolating Chinese sales from the 2009figures, how did LiuGong perform?”“Certainly, the strength of the China market was a major benefit for LiuGong in 2009. LiuGong is the marketleader in China, and we intend to work hard to keep our leadership position. China is now the world’s largestconstruction equipment market, and we expect it to remain very strong in the future, so LiuGong expects alarge part of our profitability long term to be driven by the China market. Having said that, LiuGong remainedquite profitable in 2009 in our export operations. Part of this is due to our expansion overseas in 2009. Weentered many new markets during the year, and are continuing to open new markets today.”There are mixed messages about the stability of the Chinese economy to sustain such growth. Someeconomists say that market conditions are biased towards Chinese manufacturers either by regulation or bynot giving the Wan a realistic international exchange value. There have even been Chinese official economicforecast that put the economy on 'orange alert' and at risk of over heating? How does LiuGong respond tosuch statements and does LiuGong have a strategy should a recession impact on the domestic market?“We believe China’s economy is fundamentally sound. Growth is taking place throughout China, anddomestic consumption continues to grow. China is continuing to move towards a true market economy, andwill certainly evolve in the future.One main element of our protection plan for a recession is responsibility. A company must be responsible inspending, and invest wisely to protect against economic downturns. At LiuGong, we think very hard beforewe make investments and study the market carefully to be sure that our company stays healthy. We also paya lot of attention to trends in the market and forecasting to adjust our production levels quickly in case themarket changes.”“A difficult situation for all manufacturers is the different levels of regulation demanded. Tier IV engine andemission technology being just two examples. The danger is double standards - cleaner, more efficiency,safer equipment, albeit more expensive, for advanced markets (i.e. NA and EU) but inferior, lesstechnologically advanced machines for other markets. This is going to have significant effects on usedequipmentsales and values as many markets will be taken out of the equation, because high-quality fuel,diagnostics tools, etc are not available. Would LiuGong like to comment on this dilemma?”“Long term, technology levels around the world will converge, so this will become less and less of an issue inthe future. We can already see this in some product lines, for example excavators, loader backhoes, skidsteers and several other product lines are essentially identical machines with the exception of the engineemissions level.In China, emissions level is currently moving to Tier II, and Tier III plans are coming soon, sothe emissions gap also will eventually go away. Plans for on-road Tier 4 are in place now,so the required ultra low sulphur fuel will also become available in China. Some of themost sophisticated service facilities I have ever seen in the world are in China, so clearlythe service capability in the domestic market is improving as well.The second hand market profile will change, however. Historically,China never had a strong second hand market for domestic machines.There are several reasons for this. First, the construction equipmentindustry growth is relatively recent, so the population of oldermachines is small compared to today’s market size. Second,technology used in construction machines in china, until recent years,Although LiuGong exports many of its range ofequipment, some products such as asphalt pavers arestill predominantly for the local China market.Page 14 Contractors World Vol 1 No 9

changed very slowly, so there was little incentive for a customer to upgradeto newer machines.In the past customers tended to keep a machine for its complete usefullife, so the second hand market never developed. Now, as the pace of product development increases andwith the tremendous size of the construction equipment industry in China a second hand market fordomestic machines is starting to evolve. As this develops, there will be less opportunity for importedsecond hand machines in China.”“Following on from this, Contractors World is very safety conscious and will not associate itself with anyunsafe practice - even if legal. For instance, in many markets, items such as seat belt for operators andreversing alarms are compulsory in others they are not required. Where these are not mandatory, somemanufacturers do not fit. I think this is misguided cost saving - potentially putting lives at risk. What isLiuGong’s policy - to promote safety by providing safe equipment, training, etc or to simply comply withbasic safety requirements?”“We would agree that this is misguided cost thinking. LiuGong believes firmly in providing the safestequipment possible. At a very minimum we will always meet legal requirements for whatever market wesell into. We also continually do FMEAs (failure modes and effects analysis) and other assessments todetermine what features we should provide on our machines.We adjust machine configurations, and also someoptions to provide what we feel are safe machines.However, we can put all the features in the world onmachines, but if customers do not use them, theyadd nothing to safety, so training and customereducation are some of the biggest areas where weare working to improve machine safety.”“Many markets are demanding ever more sophisticatedequipment that integrate with engineering departmentsfor increased productivity - GPS, laser technology, realtimeelectronic reporting of machine functions, loads,etc. as we move ever closer to a wireless and paperlesssociety. “Customer don't always know what they need untilthey are shown just what can be done. Is LiuGongintending to be a pioneer in this area or simply react inresponse to customer demands? (i.e. on-board weighingsystems for wheel loaders; automated trenching/returnto-digon excavators, etc.) Do you have a technologypartner?”Hydraulic excavators such as this top of the range suchas this 936LC together with wheel loader and compactorsare the driving force of LiuGong’s export development.“New technologies are good, providing that theyactually provide a customer benefit; they are easy foroperators to understand and use; their added cost iseconomically sensible, and the reliability of such features is high enough to meet LiuGong’s standards.We will not introduce any technology unless the above four conditions can be met. In some cases we havetechnology partners, such as for GPS systems. In other areas we are developing technology ourselves.For example, we have developed our own electronic controller for our excavators. This gives us theindependence to tailor features of control exactly to our machines. We are investing quite a lot into thistype of research, and our New Technologies R&D group is the fastest growing area in all of R&D, and soonwill be the largest R&D group at LiuGong.LiuGong will work to satisfy our customer requirements, sometimes by adopting technology alreadyavailable, but also, and more and more in the future we will be providing innovative features developed inour own laboratories, but once again, I mention – we will not introduce any new technology until we aresatisfied it will benefit our customers, and confident in its reliability.”“The past decade has seen a rapid demand for smaller, more compact machines - mini-excavators,compact loaders, etc. It has also seen a demand for the ultra-large excavators and loaders for mining andquarrying applications. What direction is LiuGong intending to take its product line . . and will it begin tooffer the full range of product globally?”“LiuGong’s growth plans are quite aggressive, and we intend to increase both the size and number ofproduct lines and models in the future. We already offer the largest wheel loader manufactured in Chinathe model 899 at 525 hp and 6.4 m³ bucket capacity, and are developing excavators and other products towork with the large wheel loader in mining applications.At the same time, the industry in China is beginning to change. Historically the market has been all aboutinfrastructure growth and development. This will continue for some time, but the repair industry is startingContractors World Vol 1 No 9Page 15

LiuGong participates at major events around the world -here at Bauma 2010.to develop in China. Serving the repair industrywill require more small machines.As a leader in the China construction equipmentindustry we need to supply products both at thesmall end of the product range, and at the largeend. We will offer the full range globally, but onlywhen we have the support in place around theworld to take care of the machines. Especially forlarge machines, this requires significantinvestment and long lead times. As our dealersdevelop the market and gain knowledge of themining sector in their market LiuGong will bethere with them providing the support andproducts.”“LiuGong is exhibiting at BAUMA China and isto be seen at major events around the world. I've seen the costings for some exhibitors stands and thecosts can be very high. How does LiuGong decided which events to participate in, what events to sponsorand has the company reassessed where and how it participates as a result of the current economicsituation?”“Exhibitions are very costly, and we always consider carefully our participation in such events. Some of theexhibitions we participate in are global events, so important to the construction equipment industry that wedecide at a corporate level we must participate. Other smaller exhibitions we confer with our dealers andlocal staff to determine what our participation should be. The current economic situation has had someimpact on smaller shows; some were cancelled or delayed until the next year. Generally though if the showwas held, we participate.One thing we do try to do, in keeping with our responsibility to our shareholders and customers, is tospend money at exhibitions wisely. Our purpose at an exhibition is to educate our customers about LiuGong– to teach people the value we can offer them. We don’t necessarily care if our show stand is the biggest, orthe most expensive at the show. We do care that our stands make us look professional, and that theyclearly show customers who we are and what we offer.LiuGong is 50 years old, which, in comparison to many in the construction equipment industry, is not verylong. So, obviously the company is doing something right to be where it is today. What is the drivingforce, the philosophy and strength that has made LiuGong what it is today . . . .and how different will thecompany be in 10 years time?We have two slogans that I really like. They don’t cover everything about who we are and where we aregoing, but they say a lot. First: LiuGong….We are Global!! The second is: “Creating Value ThroughCooperation”These two statements cover a lot about our attitude and approach to our business. First, in everydecision we make, we really try to think about our business from a global perspective. I can remember frommy past working for American companies, the perspective for selling was only from the American point ofview. We really didn’t understand the European market, and believed the market should change to meet ourAmerican vision of the world. Obviously, that didn’t work. At LiuGong we don’t have that limitation. Weknow there are a lot of aspects of international markets we do not understand, and we are learning aboutthem as quickly as we can. We continually send our engineers out to customers all around the world tolearn what our customers want and need. We also believe that when we set up a support organization itneeds to be staffed with local people, so all of our subsidiary companies will have people from India, UnitedStates, Russia, Brazil, etc. – there specifically to provide the right kind of support for our customers.‘Creating Value Through Cooperation’ talks about how we work as a team at LiuGong. The market ischanging fast, and we have to be very fast at responding to the market. We can only do this if we all worktogether, our dealers, sales organization, manufacturing, R&D, and all the support functions necessary toprovide quality LiuGong products to our customers.In the future I expect there to continue to be many changes. LiuGong will have more products, and willbe one of the largest full line construction equipment suppliers in the world. Our technology will continue toadvance, and we will be known for innovations in many areas. Customers will look up to us for the qualityservice and support we provide, and our products will be recognized for the strength and reliability theyprovide.”“David, thank you and I look forward to meeting with next year at ConExpo and hearing of the latestdevelopments from LiuGong.”LiuGongPage 16 Contractors World Vol 1 No 9

SPAINBobcatsupportsundergroundmovementIberpotash is the only miningcompany that extracts potassiumsalts in Spain.Established in 1998, thecompany is part of the multinational chemical group Israel Chemical Limited, the second largest producer of potash inEurope.Each year the company extracts over one million tonnes of raw material which is used to produce potash, from twoproduction centres in the region of Bages (Barcelona). Spain.The raw material is extracted from galleries between 500 and 900 m underground. Equipment has to be able to workin high temperatures and for very long hours so selection is critical. Getting equipment down to the galleries can bechallenging - even for compact equipment such as skid steer loaders. Most equipment has to be disassembled andcomponents lowered by elevator where there are then reassembled.One supplier familiar with this routine is Bobcat, who has been supplying these two mines with compact loaders,telescopic handlers and 2200D utility vehicles.The mine currently has 3 Bobcat compact loaders - a 753, 863 and S220 - which are used for transporting materials,a T3093 and T40140 telescopic handler used for maintenance purposes and the 2200D utility vehicle to move aroundthe tunnels and carry materials. All equipment is configured to meet the strict safety regulations required.Iberpotash gives top priority to occupational risk prevention, by making ongoing investments in machinery, trainingand equipment.Optimizing equipment essentialSelection of equipment comes down to reliability, versatility and productivity. The more versatile a machine can be thefewer machines that are required. The size and power of the Bobcat machines meet this criteria and the wide range ofattachments available makes them true tool carriers.Angel Reguant, Engineering Director at Iberpotash, gives his view of the use of Bobcat equipment underground.“The machines were chosen based onthe jobs that needed to be done. I wouldlike to emphasize that all three types ofmachines are very versatile.They offer a wide range of possibilities,so the investment is returned over ashorter period of time.Regarding the mobile equipmentused inside the mine, we have chosenBobcat for many years now.As far as the compact loaders andtelescopic handlers are concerned, akey issue for making the decision wasthe after-sales service offered by thedealer Bobcat of Catalunya.We are very pleased with their service.”BobcatContractors World Vol 1 No 9Page 17

VIETNAMTunnelBreakthroughCavico Corp. a leading Vietnameseinfrastructure development companybased in Vietnam ,subsidiary CavicoBridge and Tunnel ,has broken-throughthe sub-tunnel at the A Luoi Hydropowerproject. Cavico excavated approximately1,950 m (6,400 feet), of tunnel from thesub-tunnel No. 1 to sub-tunnel No. 2.The A Luoi Hydropower plant, ownedby the Central Hydropower Joint StockCo., is built on the A Sap River, located inthe Thua Thien Hue province in CentralVietnam, which is 69 km west of Hue and 160 km northwestof Da Nang. The 170 Megawatt-capacity hydropower plant isexpected to generate approximately 686 million kWhannually for the region.In July 2007, Cavico was awarded a contract to excavatea headrace tunnel at this project that is 12 km long and 5 mwide. This is considered the longest and most sophisticatedtunnel to be constructed in Vietnam. In addition to theheadrace tunnel, Cavico was also contracted to excavatefour sub-tunnels, a surge tank, a vertical shaft, and a serviceaccess road. The total expected revenue value from the ALuoi project is $53 million.“We are pleased with our progress at the A LuoiHydropower project,” commented Mr. Hai Thanh Tran, vicepresident of Cavico Corp. “The sophistication of this tunnelrequires the highest and most efficient level of technicalknowledge, in which Cavico’s talented team possess andhas done a tremendous job delivering superior work to ourcustomer. We continue to focus our efforts on completing thisproject in the safest and most timely manner.”Cavico applied the most modern technology of Robbins61R to successfully drill a vertical shaft that is 128 meterslong and 4.54 diameters wide at the A Luoi HydropowerPlant. The plant, owned by Central Hydropower Joint StockCo., is located in Thua Thien Hue province, 43 miles west ofHue city and 100 miles northwest of Da Nang city. The plantwill have a capacity of 170 MW and is expected to becomeoperational at the end of 2012.“Our ability to handle these complicated andsophisticated projects once again demonstrates our marketleadership position as one of Vietnam’s leading contractors.The completion and handing over of the above packages atthese critical projects is an important step in the overallconstruction process for Cavico. Projects are typically donein phases and once a phase has been completed, theowners will inspect and certify the scope and quality of ourwork and remit payment for that portion of the contract.Cavico has built a solid reputation of providing quality work ina timely manner and our customers depend on us to executethe task at hand in an efficient, timely and safe manner,”commented Mr. Hai Thanh Tran, vice president of Cavico.The project is being built in a valley area of 331 km² andthe total capacity of reservoir of 60.2 million m³.[CW]Contractors World Vol 1 No 9In the second package, the companyexecutes roads leading to tunnel and waterentrance.

Formwork & FalseworkSPAINChallengingbridgesuspensiontower erected inrecord timeIn the Spanish province of Toledo, abypass is under construction roundthe historic town of Talavera de laReina.A part of the project involves a cablestayedbridge 318 m long that spansthe Rio Tajo.The 316 m cable stayed section of thebridge crosses the widest part of theriver Tajo in a single span. Composing of a 36 m wide deck anchored to a single 190 m tall pylon by 38 cables oneach side of the deck, this is the widest, single pylon, concrete cable stayed bridge in the world today.The formwork solution for the slender, 180 m high suspension tower was provided by Doka España togetherwith Doka’s head office technical expertise in Amstetten, Austria. The contract for the formwork, falsework andshoring went to RMD for the abutments, piers, bridge deck and approach viaducts.The tower’s geometry is extremely challenging and standing on a foundation consisting of 56 drilled piles, the toweritself is inclined at 22 degrees from the vertical. Leaning at this steep angle, the tower utilises its own deadweight tobalance part of the load of the superstructure bridging the river valley.The load is carried by a total of 76 cables linking the suspension tower to the superstructure of the bridge. Another 76cables stay the tower off the foreland foundation. The needle-like concrete structure soars 180 m high and has to takethe vertical loads imposed by the bridge to transfer them into the sub-ground and it also has to withstand horizontal windloads, so high compressive strength H-70 concrete was a requirement for this structure.Aware of the importance of having this concrete cast as quickly and economically as possible , contractingconsortium UTE Ronda Sur Talavera used the opportunity offered by the tender submissions phase to consult with theformwork engineers from Doka whohave vast experience in structuresof this type.Telescoping is better thanre-riggingThe high-performance formworksolution would have to satisfy thehighest of requirements. Thesuspension tower was to be erectedin concreting sections each 3metres high. In cross-section thetower tapers from 17.0 x 4.0 m to5.6 x 4.0 m at the 62nd concretingsection. A craneless, speedilyThe main working platform iscompletely enclosed inside trapezoidalmetal sheeting two metres high. Theplatform sections telescope smoothlyinto each other so that the formworkadapts easily to the tapering geometryof the suspension tower.Page 20 Contractors World Vol 1 No 9

Formwork & FalseworkDoka planned a suspended platform adjustable in threedimensions to enable the workers to handle the stay cablesat the suspension tower’s overhanging face.adaptable formwork solution that would dispense withtime-consuming re-rigging was obviously needed.Doka supplied the solution using SKE100 automaticclimbing formwork with telescopically adjustableworking platforms.Doka site foreman Juergen Poechacker was on theground to make sure that the formwork solution wascorrectly assembled: “A great deal of time was savedon site because the beam formwork was delivered preassembledby Doka España. The scaffolding and theformwork were ready to go within a very short timeafter delivery to site.A complication came in the 6th lift position, wherethere was a difficult transition in the columndimensions. Once this was completed, the crew wasable to maintain an impressive 36-hour cycle forforming.”The system used was the SKE100 automatic climbing formwork,which has a high load-bearing capacity of 10 metric tons per bracket,enabling it to carry multiple platform levels. The different levels mean thatthe various operations of placing the reinforcement and handling theformwork and casting the concrete can progress separately.On the Talavera suspension-tower, the lead part of the crew handlesthe positioning of the rebar cages (pre-assembled on the ground)together with the steel boxes for tensioning the stay cables in the nextconcreting section. At the same time another part of the crew is followingup by adapting the formwork to the reduced cross-section.The telescopic function enables the platforms to be adapted to thechange in cross-section while dispensing with the need for complete rerigging.Each platform section runs on rollers on steel beams and can beslotted inside the next larger section. The Top 50 beam-formworkassemblies can be used on a number of concreting sections before theyhave to be shortened and this reusability saves even more valuableworking time.Safety is top prioritySafety is a top-priority issue on site and the process of climbing theSKE100 minimises risks. The system runs for the most part on rails,because the climbers remain anchored to the concrete structure at alltimes.In addition, nets are stretched to enclose all the working levels. Themain working platform on level 0 is fully enclosed by trapezoidal metalsheeting up to a height of 2 m. Apart from the sense of security it gives,the metal sheeting also provides a measure of protection against windand weather and helps prevent the risk of small items being dropped offthe work surface.Doka supplied SKE100 automatic climbingformwork for the pylon. It has a high loadbearingcapacity of 10 t. per bracket, so itcan carry multiple platform levels. The placingof reinforcement and formwork handling canprogress separately.Telescopic suspended platform for working with the stay cablesFormwork planning had to allow for installation of the stay cables, because a working platform on the outside face wasneeded for access. On the overhanging narrow face of the tower, the sides are stepped in from the 12th concretingsection up, forming an inside step at this level.Openings for the stay cables are located in this back-step zone. Access to these apertures is necessary, so Dokaplanned a suspended platform that can be adjusted both vertically and horizontally. The positioning of the platform at theinside step has to be accurate to within centimetres, so the platform also extends telescopically into the back cut.Contractors World Vol 1 No 9Page 21

Formwork & FalseworkWorking well in awkwwkward spacesOn the opposite side of the suspension tower, the wall features a 1 m wide and 0.3 m deep niche that also serves toaccommodate the site elevator. The challenge was to provide safe access for crew members moving betweenconstruction hoist and working platform.Doka came up to the mark by making the lowest platform level (-3) vertically telescopic. Another challenge derivedfrom the confined space available in the niche, which would accommodate only a single automatic climbing mechanism.The climber still had to be safely steadied as it climbed, of course, so Doka used the working platform to carry a traversefitted with rollers at each end and resting in the 30 cm thick walls of the niche. Struts tailing downward support theworking platform on left and right, keeping it balanced.Because of the telescopically adjustable automatic climbing formwork solution that adapts continuously to thechanging cross-section of the structure without re-rigging, work on the bridge suspension tower progressed right onschedule. As José María Saíz Aguado, the civil engineer in charge of this challenging project remarks: "Thanks to theformwork planning, we don’t have to worry about progress on our build. The speed with which the formwork can simplybe telescoped to adapt to the cross-section of the tower saves us 30 working hours by comparison with the morecomplicated process of re-rigging."Approach Ramps and Bridge DeckThe developer, UTE RONDA SUR DE TALAVERA, a joint venture between Sacyr, Aglomancha and J. Barcenas,awarded the contract to RMD Kwikform Iberica to supply formwork and falsework solutions for the cable stayed bridgeabutments, piers, deck and two approach viaducts for the bridge.Before work could even begin on this project, the river itself had to be channelled and an artificial peninsula createdto provide adequate access to the site. Upon completion of the bridge the river will be returned to its normal course andnatural state. Temporary piers were built along the artificial peninsula to support the ongoing construction of the bridge.Once the cables are in place and tensioned to take the load of the bridge the piers will then be demolished.The ground surface did notoffer adequate support for theKwikstage shoring that wouldnormally be used on a projectsuch as this. An alternativeshoring solution had to beimplemented.RMD Kwikform engineersdecided to use the foundations ofthe temporary piers to anchorMegashor towers. Whileproviding the solution needed,the temporary piers were not ofan adequate width to shore theRMD Kwikform supplied varioussolutions to the bridge viaductapproachs and supports.Page 22 Contractors World Vol 1 No 9

Formwork & FalseworkNORWAYBjørvika ReshapesOslo SkylineBjørvika is Europe´s biggestwaterfront project andNorway´s largest ever – andit is going to be Oslo’s newbusiness district.The old harbour on theeastern side of Oslo Fjord isbeing transformed into athriving residential, culturaland commercial centre.As part of Bjørvika, propertydeveloper Oslo S Utvikling ASis developing Operakvarteret(Opera Quarter, formerlynamed Barcode project).It includes a row of high-risebuildings with 10,000 officesand some 500 apartments,among others for Norway‘slargest bank DnB NOR, whoseheadquarters will move intothree bank buildings.Maxbo Teknikk AS in Vøyenenga, one ofMeva´s longest standing partners andbuilding supplier, is supplying the entireOpera Quarter project.Together with leading Norwegianconcrete contractor BundeBygg AS, theychose MEVA for all concrete works,including cores, elevator and staircase shafts, inside and outside walls, columns and slabs.Wall formwork on climbing scaffoldsMultipurpose StarTec wall formwork on the KLK 230 climbing scaffold. The clamping fixture and sliding carriage allowedthe panels to be tilted and slid back from the wall for rebar and other works. The entire construction was moved as onecomplete unit.The walls and elevator shafts were poured with the multi-purpose StarTec wall formwork on KLK climbing scaffold.The first 5 floors have different heights (2.7, 2.9,4.56, 4.1 and 4.0 m.. From the fifth floor upward, thestandard height is 3.65 m. All walls were poured with270 cm panels plus a 135 cm extension. Using thesame panel combination for different wall heightsconsiderably reduced the panel inventory on site.Stripping corners and shaft platformsShaft platforms were used inside the staircases andelevator shafts. The wall formwork was placed on theplatforms, together with stripping corners for easystripping. The shaft platforms for the elevator shaftsrested on platform girders with safety pawls restingsafely in cast-in bearing pockets. The entireconstruction took only one crane lift to the next floor.Another time saving method was leavingopenings in the wall formwork where the elevatorPage 24 Contractors World Vol 1 No 9

Formwork & Falseworkshafts were going to havedoors. This allowed workersto simply walk inside theshafts rather than climb overthe formwork and rebars.The staircases required adifferent idea because stairsfrom the lower floor weremounted immediately afterpouring the shaft walls. Here,the platform rested on girdersattached to climbing cones.After the pour, the formworkwas crane-lifted out of theshaft, followed by theplatform. Now the staircasewas flown in and mounted.Then the platform andformwork were returned tothe shaft for the next pour.Mounting the stairs on eachfloor directly after the pour had a double benefit: the stairs were in place soon after the shaft was ready and they helpedstabilise the poured shaft. At the same time, it was a perfectly safe means of access for the workers in line withNorway’s strict safety regulations.Detailing challengeThe new bank building complex for Norway´s largest bank, DnB NOR, is divided into 3 blocks A, B and C. Block A hastwo towers placed at opposite ends, 68 m and 70 m high and with a footprint of 12.4 m by 12.9 m.Between the towers and around their base, a sprawling steel skeleton construction with glass facades and a threestoreyunderground parking garage will house the bank´s headquarters. Block C will include 4 towers; in Block B MEVAformwork will climb three towers.Steel plates of various sizes were required on the outside tower walls to weld on the steel girders of the steelskeleton after concrete works finished. This posed quite a challenge to formwork detailing, as the climbing cones for theKLK climbing scaffold had to be positioned withoutcoming into conflict with the steel plates.Mobile column, flexible slabsolutionThe columns of the underground parking werepoured with the CaroFalt column formwork, whichcan be folded open and literally wheeled to thenext position. The slabs were done using theMevaDec slab formwork. The slabs of the firstthree floors had some openings. Here MEPshoring towers up to 5.4 m high were used tosupport the MevaDec for the next higher slababove the opening.To speed up work flow, a construction hoist wasused on the building’s outside. Workers could lifttheir material and work on the lower floors whilepouring the floors above them was still inprogress.Planning for more on Opera QuarterThe project shows that if planned and organized ina logical way, the use of formwork to pour concretestructures on site can be timesaving and efficient.MEVAContractors World Vol 1 No 9Page 25

Formwork & FalseworkAUSTRIASecond tube of the Pfänder TunnelAlpine BeMo Tunnelling GmbH is currently realizing the second tube of the Pfänder Tunnel, Bregenz, Austria.The new main tunnel has been excavated with a tunnel boring machine whilst tubbings have been installed asthe inner tunnel lining. As part of concreting operations for the inner shell, a crosscut for vehicle use iscurrently under construction. Due to the small length of the tunnel, an economical formwork solution wasrequired.The tunnel formwork carriage designedand supplied by Peri consisted to a largeextent of rentable Variokit systemcomponents.Situated in the Austrian Vorarlbergregion, the east tube of the Pfänder Tunnelwas commissioned around 30 years agobut is no longer able to cope with thesubstantial increase in the volume of traffic.As a result, a parallel positioned, two-lanetunnel tube is currently being constructed.Over a period of 14 months, a TBM with adiameter of almost 12 m drilled 6,600 mthrough the Pfänder mountains to form themain tunnel. The rock surface was thenlined with precast lining segments.In the event of any fire breaking out, theplanning includes 31 connectingpassageways between the old and new tunnel tubes for evacuation purposes. At the moment, the most important ofthese connections is being constructed, a 43.10 m long crosscut which is suitable for traffic. All other crosscuts withsmaller cross sections will be subsequently have shotcreted inner shells.Within a very short space of time, Peri created a customized formwork solution using their Variokit components. Themajority of the components for the project-related formworkcarriage originated from the standard product programme. Inaddition, there were a few special parts, as well as the expendablematerial including the form-lining, that had to be made.A total of seven round-shaped wall formwork elements wereprefabricated over a period of 10 days in the formwork company'sassembly hall and supplied on a 'just-in-time' basis to theconstruction site. This minimized the assembly time on the site andallowed the construction team to begin work on the first of sevenconcreting segments.The standard length of these tunnel segments was 5.90 m and,after a short period of introduction, a 3 day cycle could be achievedfor these sections. Construction of the two last segments, 3.35 mlong in each case, required two days respectively.Tunnel-lining formwork is always a challenge, butmodern systems such as developed by Peri cansimplify the process.Due to the small length of the tunnel, Peri designed amechanical solution for the formwork carriage operations.Generously-sized working levels served the simple operabilitywhich – apart from high degree of safety – was given top priority.With easy and simple spindling for shuttering and striking, theformwork carriage was moved each time to the next concretingsection by means of flanged wheels on crane rails. In spite of itsfiligree construction, the formwork carriage provided highdimensional stability which resulted in excellent concrete finishes.For planning purposes, the Peri team required only three weeksto supply the client with the drawings featuring all necessarysections and details as well as corresponding generalarrangement and assembly plans for the formwork construction.PeriPage 26 Contractors World Vol 1 No 9

Formwork & Falseworkof Companies.UNITED ARAB EMIRATESUnderground electricalpower supply system forDubaiPaschal provides universal formwork for $120 million projectwhich includes underground electricity sub-station to providepower requirements for the complex.The demand for supplies made by a rapidly growingpopulation is growing by leaps and bounds: New city sectionsare being erected on empty land, and so require installation ofall utilities. This applies to the most recent project - the $127million Mamzar Beach substation, to work for the first time inDubai with an EHV (extra-high-voltage) 400 kV line runningunderground. Internationally operating companies, includingthose from Germany, are involved.Al Mamzar Beach Park is only six kilometres away fromthe city of Dubai. Set up in 1994, the 106 ha development willbe one of the most expensive and most beautiful park andrecreation facilities of the Arabic world.Work on the shell construction for the sub-surface powerplant began in January 2010 and the plant is to be handedover, ready for use, in May 2011.The main contractor is Siemens Power Transmission andDistribution (PTD), and the sub-contractor responsible for allconstructions is Lootah Building & Construction (LBC)founded in 1973, from Dubai, a division of the Lootah GroupWorking on location is a team comprising a general manager, a construction manager, a construction site planner, atechnical manager, two construction site engineers, 3 quality managers, safety engineers, 2 foremen, 100 carpenters,60 steel fixers, and 20 workers.Construction WorksThe six construction sections are largely underground. The main components are a gas-insulated 400 kV substationincluding low voltage control centre; a gas-insulated 132 kV substation including low voltage control centre; a buildingfor the 400 kV inter-connecting transformer; the master controller for 132 and 400 kV; the control building and auxiliarybuildings with water tank, pump room, collection tanks, etc.Sulphur Hexafluoride will be used for the gas-insulated substations. This is inert, non-toxic and non-corrosive, and isa very poor electricity conductor (lower than standard atmosphere)Formormwork planningThe partially underground substation comprises only 24,000 m² . – but requires 4,850 t of gas-impervious PPC 40/20concrete, which contains 8% micro silicon. To be integrated in it are some 3,000 t of reinforced concrete. The basefoundations were built using conventional methods. Above them, Modular universal formwork from Paschal is beingused for all vertical surfaces.In the building for the master controller there were some problem areas where the heavily reinforced foundation hadvarious height changes. At a depth of 8 m, there was very little space and numerous separating walls. Since Modular iseasy to work with and comparatively light, the formwork was able to be adapted for these requirements.By developing a very effective cycle plan, only 1500 m² of formwork were necessary. Added to this were 200 m²which formed several sets of double-high column formwork (up to 9.0 m).Despite the different wall heights (up to 9.0 m), foundation height changes and a strict schedule on the part ofÉlectricité de France International, the Modular formwork satisfied the requirements with ease.PaschalContractors World Vol 1 No 9Page 27

The World of Plant & EquipmentThe Grove RT9150 allterraincrane bringstogether some of thestrongest lift capabilitiesin its class with anextremely long 79.85 m(262 ft) boom.New rough-terraincranes unveiledduring a specialcustomer day, atManitowoc's ShadyGrove facility in theUSA earlier thismonth.New RTcrane fromManitowocThe newest addition to Grove’s rough-terrain crane product line was unveiled at the event. The 135 t (150 USt) capacityRT9150E is the world’s largest rough-terrain crane, and its 60 m (197 ft) main boom is the longest on any currentproduction rough-terrain crane. At the same event, US customers got their first opportunity to see the Grove GMK6300Lall-terrain crane that was launched at Bauma 2010 held in Munich, Germany earlier this year.New rough-terrain craneThe latest in Grove RT cranes - the company’s biggest rough-terrain crane in terms of both capacity and reach - hasbeen announced. The Grove RT9150E has a 135 t (50 USt) rated capacity. It also has a 12.9 to 60 m (42 ft to 197 ft)main boom, the longest on any current production rough-terrain crane.Doyle Bryant, director of product marketing for Manitowoc, said exceptional reach is a key feature. "This crane offersa maximum tip height of 95 m (312 ft), and that will impress people. With the available length of main boom, it can reachplaces that previously required a jib. We’ve combined proven Grove technology from our all-terrain crane and roughterraincrane lines to create this RT9150E, which we believe is the new market leader."The RT9150E combines the upper works of a Grove GMK5165-2 all-terrain crane (known as the GMK5130-2 inmarkets outside the U.S.) and the lower works of the 118 t (130 USt) capacity RT9130E rough-terrain crane. The resultis a high-capacity crane that sits on a compact and durable carrier with obvious applications for industrial work."There will be a lot of applications in refineries, power plants and otherlarge projects where space is often tight, so the compact carrier gives thecrane additional value."The 6-section main boom on the RT9150E benefits from Grove’s patentedTWIN-LOCK pinning technology that offers a lighter boom with greaterstrength. When working with the 60 m (197 ft) boom, customers can achievea maximum tip height of 63.5 m (208 ft 10 inch). Maximum radius with themain boom is 54.8 m (180 ft) and at this distance the crane can lift 1,724 kg(3,800 lbs.)An 11 - 18 m (36 -59 ft) bi-fold lattice swingaway extension offers fartherreach, with fixed offsets of 0º, 20º and 40º. When working with this jib, theRT9150E can reach a maximum tip height of 81.4 m (267 ft) and a maximumworking radius of 67 m (220 ft), where capacity is 2,000 lbs.To reach the maximum tip height, users will need two additional inserts,one 26 ft and the other 20 ft, which fit between the boom nose and the bi-foldswingaway. Adding these extends the maximum tip height of the crane to312 ft, while taking the maximum outreach to 220 ft, where capacity is 907 kg(2,770 lbs).When working with the 60 m (197 ft) boom, customers canachieve a maximum tip height of 63.5 m (208 ft 10 inch)Page 28 Contractors World Vol 1 No 9

Provides a total tip height of 81.4 m (267 ft)Removable front and rear outrigger boxesprovides up to 8552 kg (18,854 lb) of weightreduction for transportation.Engine optionsNot only does the crane offer excellent reach, the RT9150E isalso the strongest rough-terrain crane available from Grove. Whenworking with its full standard counterweight of 17,690 kg (39,000lbs), the crane has a lift advantage of almost 60% over the nextmodel in the line.The RT9150E has a chassis length of 9,855 mm (32 ft 3 in). withthe outriggers attached, or 8,077 mm (26 ft 6 in) when removed.Overall length with the boom stowed is 15,899 mm (49 ft 10 in),width is 3,788 mm (12 ft 5 in) and overall height is 4,166 mm (13 ft 8in) Gross vehicle weight is 78,925 kg (174,000 lbs) — the same asthe RT9130E.For ease of set-up and tear-down, the crane can easily removeand install its outrigger boxes. Similarly, the 17,690 kg (39,000 lbs)of standard counterweight, plus the optional additional 19,886 kg(24,000 lbs), can also be hydraulically installed and removed.New generation cabA significant design innovation on the RT9150E is the newoperator’s cab, the first from a new generation of Grove cabs thatoffer better visibility and comfort. The "full vision" designincorporates more glass, including in the sliding door. The cab canalso tilt up to 20º for operator comfort and visibility.Inside the cab, operators have Grove’s EKS5 load momentindicator and also ECOS electronic controls. As well as managingand monitoring the crane’s major functions, ECOS also givesfeedback on a variety of conditions, including fuel level, low brakepressure, hydraulic oil temperature, transmission oil temperatureand engine stop.Manitowoc is offering a choice of engines for the crane. A Cummins QSC8.3L engine with a 234 kW (300 hp) at 2,200rpm rating is available for customers in the U.S. This engine is Tier IVcompliant. Outside the U.S., a Euro Stage III compliant version is offered.The engine drives a Clark Powershift Transmission with six forwardand three reverse gears. Four-mode steering and driving is offered (as itis with all Grove rough-terrain cranes) allowing operators to choosebetween front-only, rear-only, crab and coordinated options.Maximum travel speed (without counterweight) is 24 km/h (15 mph).Outside turning radius 9.7 m (31.6 ft) and, depending upon configuration,theoretical gradeability is 70%. For smoother off-road travel, automaticfull hydraulic lockouts on rear axle permits 25.4 cm (10 in) oscillation onlywith boom centred over the frontReaching out to customersLarry Weyers, executive vice president for Manitowoc Cranes in theAmericas region, said even during challenging economic times, it isimportant to focus on product innovation."The cranes that we showcased this week are a testament toManitowoc’s on-going commitment to our customers to provide the mostproductive and profitable cranes," he said.

The World of Plant & EquipmentWorldwidelaunch forredesignedbackhoeloaderandmore from TerexAt the recent GaLaBau trade-show in Germany, probably Europe’s largest event for landscaping, horticultural,recreational and associated industries, Terex introduced to the world a completely redesigned TLB840 sideshift backhoeloader.Jon Beckley, Product Manager said “Never has a Terex backhoe loader been so versatile, innovative and efficient asthe new TLB840”. The new backhoe was demonstrated to show the new features including a much more spacious andergonomically designed cab to provide an optimal interface between driver and machine. Pilot controls for the backhoemake for easier operation, which means more productivity. An adjustable steering column and the centrally mountedinstrument cluster enhance operation for travelling or when used as a wheeled loader. Improved visibility, enhanced airconditioningunit and easier opening of rear windows all contribute to the improved operator environment.The TLB840 can be equipped with a curved boom arm which gives better reach over obstacles and for truck loading.The curved boom also reduces maximum height when roading or being transported. There is also the option of a newlydeveloped telescopic arm for digging depth of up to 5.4 m or forward reach of 6.7 m.The new model is powered by advanced engine, with intercooler, delivering 70 kW engine with intercooler. With the‘Power-Synchro’ transmission, the combination reduces the power loss by 9%, lowers fuel consumption and increasesproductivity. A new, enhanced braking system increases braking torque for shorter braking distances.European launch of compact track loaderTerex Compact Track Loaders had the landscaping firmly in their site when they had the European premiere for thePT30 compact track loader.The company presented three CTL, at GaLaBau in Germany during September. Already well established for morethan two decades in the USA by ASV, the machines are well proven. Terex acquired ASV in 2008/ With this Europeanintroduction, the range is now available under the roof of the Terex group worldwide.The Posi-Track undercarriage with patented technology ensures that the special rubber chains of the CTLs followeven small bumps. The resulting traction increases performance with little damage on even the most sensitive ofsurfaces..The Terex Posi-Track PT30 has a standard operating weight of 1,500 kg and a bucket capacity 191-250 l (0.25 m³).The PT60 is 2937 kg with a bucket capacity of 360-435 l (0.4 m³). The currently largest available inEurope, the PT80 has a weight of 4070 kg and bucketcapacity of content 420-500 l (0.5 m³).With engine power of 25.1 to 44.7 - 56 kW, lowerweight and more powerful traction but structurallydifferent loaders significantly higher speeds arepossible. The PT60 and PT80 are 17.7 km/h areamongst the fastest machines of their class.The driver benefits from a modern, high-level cabin.The unique cushioning to the undercarriage makes theCTL especially comfortable for long distances. Even inFollowing their presentation at GaLaBau 2010, Terexcompact tracked loaders are now avialable worldwide.Page 30 Contractors World Vol 1 No 9

The World of Plant & EquipmentThe Terex TL80 illustrated has been joined bythe new TL100 as shown at GaLaBau,difficult terrain, the handling of the two joysticksare positioned for convenience and operatorcomfort.The PT30 is equipped with an operating weightof 1.5 t and is 1,219 mm wide and 2,845 mm long.The model has proven popular in the USA forcreating new gardens and parks and even whenworking in buildings. The PT60 is also a verypopular, universal skid steer loader model, has awidth of 1676 mm and a length of 3251 mm. Thebig PT80, which is for large-scale landscapingand for more demanding applications measures3867 mm and 1778 mm. It comes with 457 and508 mm wide track.New wheel loaderFollowing the launch of the TL80 at Bauma 2010, Terex presented the TL100 at GaLaBau, a 5,700 kg machine withbucket capacity up to 1.55 m³. It is powered by a Deutz TD 2011 L04 W diesel engine rated at 54 kW.As we get ready to publish this issue, Contractors World is awaiting more details from Terex on the availability,configurations and distribution of these models as shown at GaLaBau,.TerexNew drill rig especially for narrow veindrillingA new face drilling rig for narrow tunnelsand mines has been introduced by AtlasCopco. Based on its well-provenpredecessor, the Boomer 104, the newBoomer T1 D delivers a range of technical andenvironmental improvements.In the world of underground mining where narrow tunnelsand drifts have limited space, a small and flexible face drilling rig makes asignficant contribution to productivity. Since the 90s, this role has been filled by AtlasCopco’s Boomer 104. Now Atlas Copco has launched its successor – the Boomer T1 D.The new machine retains the features and capabilities of the well-liked Boomer 104, but nowintroduces an extensive range of improvements and upgrades, all aimed at improving productivity,safety and operator comfort.The range of new improvements and options include a more powerful and cleaner Deutz 4 -cylinder Tier 3 enginefor higher tramming speed and environmental benefits. A redesign of the boom suspension system reduces stress onthe machine, thereby increasing service life and improving operator comfort when driving. A more ergonomic andcomfortable cabin, with better visibility, is one of a range of optional extras, and the serviceability has been improvedwith service points positioned for easier accessibiity and convenience.An important improvement has been made to the carrier frame. The new frame is stronger, has a lower centre ofgravity and an oversized ±40º articulation to cope with demanding operating conditions.The first Boomer T1 D was tested at the Lovisa lead/zinc mine in Sweden where it achieved top results compared tothe mine’s previous Boomer 104. Operators of the machine praised the improved ergonomics and drilling performanceduring the trial.In standard configruation, the Boomer T1 D, equipped with COP 1638, COP 1838 or COP 2238 rock drill, has anoperating weight of 11,000 kg and a tramming speed on level ground of up to 14 km/h. Coverage area is 23.3 m³.Maximum width is just 1,300 mm and with the generous articulation joint, a fully rigged machine can turn through 90º injust 2,800 mm.Atlas CopcoContractors World Vol 1 No 9Page 31

The World of Plant & Equipmentrestore it as soon as the levers are moved again.New Midi-Excavator fromYanmarYanmar has introduced the new SV100-1 midi-excavator toreplace the SV100. The new model has been redesigned totake into account the users’ comments as well as technologicalevolutions, particularly in the area of environment and energysavings. The industry had the first opportunity to see this atGaLaBau, in Germany.The machine’s operating weight is increased by nearly 400kg to 9,625 kg in order to improve significantly lifting capacityand stability. The SV100-1 is able to lift 4.7 t at 3 m over frontand 3 t over side, which enables the use of bigger capacitytools, increased productivity and overall improved efficiencies.The SV100-1 is fitted with a new engine that complies withthe EPA STAGE III standards. It includes an EGR system aswell as “Auto-Idle” and “Eco” functions,. When activated, theAuto-Idle function will automatically reduce the engine speed tothe minimum after 4 seconds without action on the levers, andThe Eco mode can be activated simultaneously and induces a reduction of the engine speed while maintaining thesame torque to work in optimal conditions.The combination of the Yanmar 4TNV98T-ZSBV-1, a new engine, and Yanmar’s VIPPS hydraulic system giveslower fuel consumption with increased performance. Energy savings are estimated at 20% per excavated cubic meterin the classic mode (0.125 l/m³) and 26% in the Eco mode (0.115 l/m³) compared with the former model. Performance isimproved since the machine can excavate 68.7m³/h in the classic mode and 64.8 m³/h in the Eco mode, which represent7 to 14% more digging volume compared to the previous version.For more convenience, an automatic gear shift device can be switched on in order to adjust automatically themachine speed according to the required power output.The hydraulics have been upgraded. A new motor has a swing torque which is 11% higher allowing a quicker,smoother and more secure use even when working on steep slopes. The 3rd circuit is proportional as standard and itsextension can be supplied as an option. The optional 4th circuit isproportional as well. Safety valves kits are also available as an option andTechnical data SV100-1are fully compliant with the latest amended European standards (EN 474-Operating weight 9625 kg 5 – CEN/TC 151/WG1).(rubber crawlers)As with all manufacturers, Yanmar is ever more conscious of the needEngine Yanmar 4TNV98T-ZSBV-1 for optimizing operator comfort and safety. The SV100-1 has a cab that isWidth2320 mm considerably larger. Operators have 40% more space inside the cabin;Bucket digging force 6980 kgf the internal width has been increased by 170 mm, and the foot space hasbeen increased by 30%.Arm digging force 4760 kgfThe travelling levers are equipped with large ergonomic pedals. TheMax. digging depth 4290 mmpneumatic suspension seat can be adjusted either alone or together withMax. dumping height 5150 mm the operating levers. In addition, the noise level is significantly reduced –from 78 dB(A) to 74 dB(A) – and the air-conditioning enables atemperature reduction of 7° C below that of the previous model.New European CompanyIn September 2010, Yanmar Construction Equipment Co., Ltd., located in Fukuoka, Japan, purchased all shares ofAmmann Yanmar S.A.S. from Ammann Group Holding AG. Up until that time, Ammann Yanmar was a joint venturecompany specializing in production and sales of compact construction equipment. The name and status of thecompany is now Yanmar Construction Equipment Europe S.A.S.Under the new company, construction equipment will be marketed under the Yanmar brand and abandon the dualbrand. The strategic development of both companies made the timing right for Yanmar to take full operation andtransform the company into a fully owned subsidiary.The volume of compact construction equipment sold in Europe under the Ammann Yanmar brand representedapproximately 30% of the entire volume of compact construction equipment units manufactured and sold by the YanmarConstruction Equipment - making Europe a major market.The joint-venture was established in 1989 as a France-based company with each having an equal investment ratio of50%. Ever since its establishment, the company manufactured and sold in Europe compact construction equipmentunder the Ammann Yanmar brand.Yanmar Construction Equipment Europe S.A.SPage 32 Contractors World Vol 1 No 9

The World of Plant & EquipmentNew Ditch Witch MT12 MicroTrencher for fiber cableinstallationThe new Ditch Witch® MT12 MicroTrencher is specifically designed for fast and efficient installing of fibre-optic cable inurban environments. It is designed to quickly and cleanly slice through asphalt to create trenches into which fibre-opticcable can be installed.Throughout the world, demand is increasing for faster broadband and telecommunications systems, necessitatingan increase in the installation of highspeed fibre-optic cable for commercial and residential use.The trend today is for utility companies to put new cables underground to reduce the risk of cable damage due to theelements (e.g. storms and high winds) as well as to prevent theft - a growing problem in some areas that has effectedcopper cables particularly due to high scrap metal values. Overhead cabling is also unsightly but has been thepreferred option in the past because of cost.Ditch Witch are trying to change this attitude by developing cost efficient solutions to enable in-ground installation.The MT12 is one example of this.Using specially designed and manufactured saw blades, the Ditch Witch MT12 cuts through asphalt to create theideal trench for fibre-optic cable installation—from 19 mm (0.75 inches) to 32 mm (1.25 inches ) wide, and up to 305 mm(12 inches) deep—in one quick, efficient pass.The narrow, shallow trench created by the MT12 enables contractors to install fibre above existing utilities, so there isminimal disruption of surrounding infrastructure and roadways, which saves time and money.The MT12 offers a choice of four saw blades with widths. Each blade can beeasily changed in the field with standard hand tools, reducing downtime. The bladesfeature conical bits that can be replaced in the field; a design that extends the life ofthe blade and reduces maintenance expense.The trenching depth is mechanically adjustable—from 152 mm (6 inches) to 305mm (12 inches) in 25 mm (1 inch) increments. This helps the operator quickly set thedepth to match job specifications and maintain a consistent depth for the entire lengthof the trench.The microtrencher can also be manually tilted 6º to the right or left, which helpsthe operator maintain a true vertical trench on uneven surfaces.The MT12 offers a choice of foursaw blades with widths of 19 mm(0.75 inches) , 0.95 inches (24mm), and 32 mm (1.25 inches).Where it is necessary to cut a trench right next to and parallel to curbs and gutters,the MT12 saw is designed to hydraulically traverse 610 mm (24 inches) from thecentre of the machine to the right.The customer can choose whether to run the vacuum excavator hoses in front ofor to the rear of the trencher, depending on jobsite conditions. It can also beequipped with onboard chutes that deposit spoils along the side of the trench, foreasy cleanup when not using the FX60 microtrenching vacuum system.The MT12 MicroTrencher is not only for installing cabling. It can also be used for other roadway applications such ascutting expansion joints, utility repair (e.g., sawing square sections of roadway prior to excavation), and maintenance(e.g., trimming the rugged edges of new layers of asphalt to make a clean shoulder).Ditch WitchContractors World Vol 1 No 9Page 33

Combined with a very high-pressure, 151 bar(2,200 psi), piston pump and the unit is able to consistently deliver 10 t of materialper hour and achieves vertical pumping distance of 90 m (300 ft).In order to prevent material build-up and hardening, as well as possible damageto the unit must be thoroughly cleaned after each use the same as other mixer/pumps. This can be time consuming but on the MX-10 has been designed to makethe process quick and simple. The receiving hopper swings out, allowing easyaccess to its lower area and the swing tube for fast cleaning and maintenance. Theentire flat pack can be removed from the frame in just minutes to provide easieraccess for maintenance. For enhanced cleaning ease, a hydraulic pressure washeris an available option.A hydraulic agitator ensures the mix stays consistent and blended. The agitator'shigh intensity mixing action assures that the refractory grains and binders remain insuspension as the material is loaded into the pump. The re-mix hopper with agitatorhas a capacity of 1,134 kg (2,500 lbs).A 2 m² the operator platform gives increased space and allows the electrical controls to be ideally positioned toprevent debris and water from making contact with the electrical components. Lifting eyes are mounted on the platformfor easy lifting and transport.The unit is available with either a John Deere 4045T 74 kW (99- hp) or Deutz BF4M 2012 76 kW (102-= hp) watercooleddiesel engine. It's also available with dual 30 kW (40 hp) electric motors. The MX-10 is CE Certified, meetingEuropean Union safety standards for equipment operation and backed worldwide by Blastcrete's unmatched customerservice and support.New box-shape jaw forCombiCutter.BlastcreteAtlas Copco has introduced a new box shaped jaw for the CC3300 hydraulic CombiCutter allowing the recycling rate to beincreased in demolition jobs and the recycling process within thecrusher to be simplified."With the box-shape jaw we are able to achieve defined sizesof demolished material which are ideal for the crusher plant nextin line,“ Wolfgang Hohn, Product Line Manager Silent DemolitionTools with Atlas Copco explains. "We cut the demolishedmaterial on three sides in one go to prevent too long pieces ofrebar and therefore substantially simplify the separation of theCC 6000 U, left, and CC 3300 B (box shape), right different materials."The new shape also has a positive effect on the amount offines and dust produced on the demolition site. "More high-grade material can be recycled and the environment is betterprotected by the reduced dust emissions" Hohn continues.The "B" box-type jaw has been designed for the CC 3300 CombiCutter. Apart from this, the "U" type jaw fordemolition work in reinforced concrete and the "S" type jaw for cutting steel structures are available.Atlas CopcoPage 34 Contractors World Vol 1 No 9

Operating speed 0-30 km/h while maximum travel speed is 6 km/h.Another patented solution is the parallelogram front axle, which reduces wear at the tyre shoulders while increasingtraction and wheel control on a grade.The patent-pending round down holder at the front side of the cutter housing minimizes the accumulation of milledmaterial and reduces clean-up work on the track.With the latest introduction, the range of Dynapac compact cold planers comprises five models.New wheel loader for miningapplicationsDynapacKomatsu America has introduced the WA1200-6 wheelloader for demanding mining applications.The new 216.4 t (477,100 lbs) loader has been designedusing user feedback as well as latest advance in technologyto deliver environmental, technological and ergonomicenhancements for even greater productivity, while loweringoperating costs.The new WA1200-6 is powered by a highly-efficientKomatsu SAADA16V160E-2 which means output has beenincreased by 98.43 kW( 132 hp) to 1,3156 kW (1765 hp).The engine meets all EPA Tier 2 emissions requirements.The use of an electronic governor results in low fuel consumption, with quick throttle response to match the machine’spowerful tractive effort and fast hydraulic response. The new dual-mode active working hydraulic system allows theoperator to select between normal and powerful loading, while the optimum oil flow in the working system increasesefficiency and reduces cycle times. Increased engine output and the optimized hydraulic system provide outstandingproduction and performance.For the operator, the engine RPM control system, with auto deceleration, allows the operator to set the engine RPMat the optimum work performance level and control speed smoothly with the accelerator. The variable transmission cutoffsystem for the left brake pedal is adjustable by a switch at the operator’s seat. When loading, the low setting reducesbrake impact to prevent spillage, while the high setting can be used for travelling.An additional torque converter cooler is added as standard equipment to reduce oil temperature and increase coolingcapacity. A new pump with increased oil capacity ensures efficient hydraulic cooling and the circulation revised to loweroil temperature. Air cleaning has been improved with larger elements and two additional air cleaners for added capacity.Details specifications have yet to be released but Contractors World understands that it will feature a 20 m³ bucketwith breakout forces similar to the existing model. The new model will be produced at Komatsu's facilities in Japanwhich is used for all the company's large mining machines.At this time Komatsu has not made any announcements on where in the world the new model will be available orwhen, except that it is expected to be available to the North American market in 2011.Komatsu AmericaContractors World Vol 1 No 9Page 35

Bauma China 2010- more than ‘just another’exhibitionA comment by Roger LindleyIt is very easy to get cynical about exhibitions - after all, there are so manyranging from vast international exposiums such as Bauma in Germany tospecialised industry sectors, localised event or by country.Bauma China is rapidly approaching and so is the Big 5 in Dubai andcountless other events around the world. After 30 years in the industry, I haveseen exhibitions large and small and still cannot find what it is that make anevent successful. One year an exhibition is a big success with recordattendance. Repeat the formula 12 months later and the aisles are empty.Why?I am of the opinion that the world is moving in the right direction in regard to major international exhibitions. Earlierthis year we had Bauma in Germany - the biggest, most successful show of its type, held every third year and popularthroughout Europe (and the rest of the world). Next year is ConExpo a hugely important event for the Americas andalso a draw for international visitors. November 2010 sees Bauma China which is of major importance to the Asiancountries. These three events, effectively share the world - geographically, if not by visitor numbers.Why should people go to Bauma China? For exhibitors it is a probably the most important opportunity to showcaseproducts and capabilities to the still growing Chinese domestic market.Although doing business in China is not always easy - buying or selling, for those prepared to meet the challenges,the rewards can be significant. The fact that the show is a sell-out, even after the organisers made more spaceavailable shows that manufacturers recognise the importance of this part of the world.For those in the construction, mining, quarrying and related industries, Bauma China is also an opportunity to see,compare and identify new products that could contribute to higher efficiency and productivity at lower cost. Lower costsare very much a driving force in today’s embattled economic situation. However, for those visiting from outside of China,there will be a lot of machinery which, although acceptable in Chinese construction, mine and quarry sites, they do notmeet regulations for safety, emissions, etc. required by many countries.This is not a criticism of Chinese manufacturers, for all companies produce to market demands and, as companiessuch as Sany, LiuGong and many others are showing, with sufficient interest from overseas, they are prepared to makethe necessary modifications to ensure that machines exported meet EC or other country regulations.Regional exhibitions have their placeMajor events such as mentioned above are important for all in the industry, but cities where such events are held chargeexorbitant rates for hotels, etc. which many in the industry cannot afford. Smaller, events such as SMOPYC (Spain) ,Intermat (France), SAMOTER (Italy) and similar are highly successful from a continent/country perspective - easier toget to, lower overall costs and still showcasing products more clearly defined for their region. Events such as theWorld of Concrete (USA) are ideal for those in specific industry sectors. Minexpo is another such example.Contractors World encourages all in the industry to visit asmany shows as they can because each has something differentto offer and have different exhibitors. When visiting trade eventsdo not focus on the big stands of the larger companies. Taketime to look at some of the smaller exhibits. Bigger does notalways mean better and there are many interesting productsand service to be found in the myriad of 3 m x 3 m booths thatare part of every trade show.And, if nothing else, you will amass a collection of pens,note-pads, bottle-openers and other giveaways to keep yourstationery cupboard stocked until the next event.
