Bingo! Full housefor JCB high reachdemolition rigA leading Scottish civil engineering and demolitioncontractor has bought a JCB JS330 HRD trackedexcavator, featuring a high reach demolition rig,to carry out a series of prestigious demolitionprojects in the North of Scotland.The machine was purchased by W MunroConstruction, based in Alness in the ScottishHighlands and supplied by dealer Scot JCB.The 21-metre JS330 HRD – which comprisesa three-fold boom fitted to a speciallyadapted demolition specification JCB excavator– is pictured here in Inverness dismantling theCarlton Bingo building in preparation for a newdevelopment by Premier Inn.Roderick Munro, General Manager ofW Munro Construction, said: “We chose thepurpose-built new JCB model to further enhanceour specialist expertise in controlled demolition.It becomes the only high reach demolition rignorth of Dundee and gives us a significantadvantage when tendering for major projects. Itis the perfect machine for our requirements andis working well.”William Munro Construction (Highland)Ltd - incorporating Munro (Highland) Ltd - wasestablished in 1977, initially to provide buildingand civil engineering solutions to clients includingHighland local authorities, oil platform constructioncompanies, housing associations, distilleries andprivate developers.Over the last 30 years, it has produced highquality project services and is a member of theFederation of Master Builders. Since the companywas founded it has branched into areas such ascontrolled demolition, asbestos removal, roadconstruction, site servicing, water supply, marineAtlas Copco attachments reducebridge demolition time by 25%works, trade waste management, recycling andskip hire.Introduced in response to growing customerdemand, an innovative modular system on theJS330 HRD provides greater versatility on siteby providing the optimum boom configurationfor each demolition task. With the new system,the high-reach boom can now be hydraulicallydisconnected into a docking cradle once the highlevel work is complete. The specially adaptedJS330XD base machine can then pick up aThe specialist demolition team of the HasseltbasedBVBA Baldewijns & Co, faced a toughchallenge. They had to remove two 100 mlong bridge sections of the E 313 over the A2highway at the Lummen highway interchangeover a single weekend and remove the rubble.On Friday evening, after having laid a sandbed to protect the underlying asphalt road, 12excavators were put to work with heavy breakersand concrete crushers. The most powerfulbreaker on the site was an Atlas Copco HB3000, and suitable for excavators in therange of 32 to 50t. It is a robust tool that canhandle heavy demolition jobs; a real productionmachine, 7 days a week, 24 hours a day.A total of 4,000m 3 of concrete was demolished,sorted and removed, including 300tof reinforcing steel. The job was completedin only 40 hours, far less than the scheduledtime of 55 hours. This impressive result wasprimarily achieved by thorough planning witha tight schedule, sufficient equipment, and, the45 professional operators.The starring role was played by the newestconcrete cutter from Atlas Copco. TheCC 6000, equipped with universal jaws thatmade it possible to cut through and crush thebearing beams of the bridge and then cutthrough the heavy reinforcing bars.“We needed really heavy equipment toget this job done within the schedule,” saysBaldewijns & Co director Steven Lisens. “TheCC 6000 concrete cutter contributed to thesmooth progress of the works and the finalresult. The cutter had no problem at all withthe size of the beams. Its crushing power andtwo-piece boom which is designed for mediumheight demolition, or for working at ground leveland below.In addition to the specialist boom configuration,it features heavy-duty mainframes,undercovers, side buffers, turrets and track motorguards, extra duty dippers and linkages. With aFOPS cab guard and cyclonic engine pre-filterfor dusty conditions, it is well equipped for a longlife on the toughest demolition tasks.www.jcb.comhigh cycle time exceeded all of our expectations.The performance and the reliability ofthe products from Atlas Copco have reallyconvinced me. The results achieved with theCC 6000 and the HB 3000 have inspiredus to purchase a new Atlas Copco HB 4700hydraulic breaker.”www.atlascopco.comTechnical data CC 6000:Carrier weight class 58 – 85 tWeight6500 kgWorking pressure 150–170 barFlow450 – 550 l/minCrushing power 180 – 830 tonOpen/Closing cycle 4 sec.52 PDi • Issue 2 • May - June 2011
New 710 V Classic hydrodemolitionrobot from Aquajet SystemsHydrodemolition equipment company Aquajet Systems haslaunched its next generation Aqua Cutter 710 V Classic seriesof 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 atypical 1 000 bar pressure and 250 l/min, the robot handlesremoval depths to approximately 1 000 mm of concrete ifrequired.Aquajet has recognised that there is a frequent demandfor its hydrodemolition systems with reduced computer controlallowing manual handling with, for example, flow controlvalves for oscillating speed, roller speed, lance angle speedand mechanical stops for operation widths and lance angles.Improvements have been made to the settings ofprogrammes with several parameters easily selected andadjusted on the colour display with multi language operatorinstructions.Aquajet robots are equipped with the patented EqualDistance System. Regardless of the set lance attack angle,the system controls and maintains the nozzle’s distance fromthe concrete surface. Maintaining an optimum distance, EDSensures that no power is lost due to the nozzle being too farfrom the surface, which will ensure a 15 to 20% increasein removal capacity. The lance attack angle can be setfrom –30° to +30º allowing for efficient removal ofconcrete under rebars.The patented Intelligent Sensing Control is anadvanced sensing system and features noelectronics, resulting in a more efficientproduction with less stops due to problemswith sensors.Total length variesfrom 2.65 meter – 2.85m and the new unit is2 meter wide. Minimum height is 1.42meter and, with a sturdier base, an extendedfree vertical reach of up to 7 meter is possible and a4 m width operation.The variable width chassis provides maximum stabilityduring set up and operation. In its narrow version, accessto the tightest passages like doorways, alleys, footbridges, ispossible. The variable track width extends from 1.04 meterto 1.64 meter and the unit weighs 2.3t.A new improved rubber lined splashguard on the powerhead ensures improved noise reduction. Easy service accessis also assured with gull wing hoods and fold down hydraulicsfor cleaning and maintenance.www.aquajet.sewas able to expose the rebar with no damage, allowing it to bereused for the replacement beams. ISOTEC’s hydrodemolitioncontract on both bridges was completed within 20 days withthe damaged beams lifted clear and replaced in two nighttime operations by main contractor ICAFAL. Hydrodemolitionis a relatively new concept in South America, but widely usedthroughout Europe, with ISOTEC leading the way in Chile.The company had initially specialised in high pressure watercleaning. “Taking advantage of this experience it was logical toexpand our business in to hydrodemolition, taking delivery ofthe new Aqua Cutter HVD-6000 from Swedish manufacturer,Aquajet Systems,” says Jose Alday.Chilean bridge beamsreplaced with hydrodemolitionFollowing earthquake damage to two bridges over the Santiago’sSouthern Approach (Acceso Sur Santiago) highway inChile, hydrodemolition specialist contractor ISOTEC Ltda reliedon an Aquajet HVD-6000 Robot to assist in removing damagedconcrete beams and retain the rebar. The 46 km long recentlyopened highway has been designed to relieve traffic flow onthe Chilean capital’s southern approaches to handle up to 25million vehicles per year.According to ISOTEC’s Jose Alday, the role of the AquaCutter was to remove the concrete above the beams allowingthem to be lifted clear and replaced, whilst saving the rebar forreuse in installing the replacement beams. “The hydrodemolitiontechnique proved ideal with no collateral damage to theremaining structure whilst removing the damaged concrete,”he said. “We also had to guarantee minimal impact for thehighway users, allowing the highway to remain open throughoutthe removal process.”Operating to a depth of up to 200 mm, the Aqua CutterHydrodemolition techniqueConcrete rehabilitation using hydrodemolition is becoming anincreasingly important aspect of civil engineering and buildingrenovation projects. Applications can involve cleaning, roughening,removal of deteriorated concrete and even cutting. Waterjetting is actively used for the removal of chloride damagedconcrete layers down to the reinforcement bars or to a depthwhere the chloride content is at or below the permissible level.It causes no damage or vibration to the existing rebar andprevents damage or loosening of adjacent concrete and parts.Using a high-pressure jet of water, supplied at a pressure of1 200 bar and a flow rate of 200 litres/min by the company’sWoma pump, coupled to the HVD 6000, the Aqua Cutter robotwas able to blast the concrete without causing any damage tothe reinforcement bars or adjoining concrete.The Aqua Cutter robot from Aquajet is considered themost advanced offering a wide variety of features ensuringtop quality results are achieved safely at a high productionrate with low operating and on-going costs. The robot is smalland compact but at the same time big enough to handle thetoughest applications.www.aquajet.seIssue 2 • May - June 2011 • PDi 53
