Wall sawing -drastic costof processreductionWhen Carbodiam Research and Developmentdepartment helps the sawing and drillingcontractors to reduce their cost of process.For more than 55 years Carbodiamhas been developing new sintering andmanufacturing processes with the objectiveof constantly improving diamond tools anddrastically improving their performance. Oneof the main targets is to help customers tolaunchingEFT Forging Technologyfor diamondsegments. The forgingprocess makesit possible to apply aviolent hit on the segmentschanging themicrostructure. Thisproduction processhas made it possibleto enhance both thereduce their total costof process, includingtool wearlife, cuttingspeed,reliability,ease ofmaintenanceandmanipulation.CarbodiamGroup80 PDi • Issue 2 • May - June 2011cutting speed and the wear life of the diamondtool. The segments have a specialdesign, reducing vibrations and makingthe cut smoother. Forged segments alsoallow a unique high quality welding zone,resulting in a more secure tool.The marriage of this unique andpatented technology within the diamondindustry, the use of the highest qualitysynthetic diamond and metallic powder,together with Carbodiam’s long experience,have brought to the professional marketthe wall saw blade called The Alligator VX.After hundreds of square metres cut,in the hardest heavily reinforced concreteaggregates, the Carbodiamforged AlligatorVX has shown toachieve 35% morethan a standard wallsaw blade.Contractors arealways looking to improveperformance, inorder to reduce costsand the <strong>com</strong>panyclaims the AlligatorVX wall saw blade isthe ideal solution.New HEPA Vacuumfrom CS Unitec Providesa Clean, SafeWork EnvironmentCS Unitec’s new CS 1225 H wet/dry HEPAvacuum exceeds the EPA filtration standardof 99.970% and 0.3 microns. The CS 1225H’s HEPA filter efficiently captures 99.999% ofparticles up to 0.1 microns, providing a cleanerand safer work environment.The CS 1225 H includes a tool to hoseadapter to easily connect portable power toolssuch as concretegrinders or sawsfor dust removalwhile the tool isin operation. A“Power Take Off”outlet activatesthe vacuum ON/OFF from thepower tool switchand includes a10-second shutoffdelay to clean anydust left in the hose. An automaticshut-off sensor protects the motor and filtersduring wet vacuuming.Its Electromagnetic Pulse Filter CleaningSystem shakes the HEPA filters to remove dust,maximizing suction and doubling filter life. Thevacuum senses when the filters are clogged andthe suction power or air flow is restricted, cleaningitself when the vacuum is turned on and againwhen it is turned off. This feature can be set toactivate automatically or manually.A 15’ hose and 25’ power cord make theCS 1225 H ideal for most construction jobs.Weighing less than 25 pounds, it is portable andvery convenient to use on the job site or in theshop. A cleaning kit, including wands, nozzles andhose is also available.www.csunitec.<strong>com</strong>New Doosan22.5 t ExcavatorDoosan has launched a new narrow widthcrawler excavator, the DX235NLC with monoboom, weighing 22.5t. Just 2.54 m wide, theDX235NLC excavator meets the transport widthspecifications of road regulations in countriessuch as Italy. The DX235NLC offers a <strong>com</strong>binationof features including a heavy counterweight,reinforced 12.5mm shoe plates and an overdimensionedfront body section. The oversizedboom and counterweight in the DX235NLCprovide higher lifting performances than otherexcavators in the 21 to 24t category.www.doosanequipment.euNew Bobcat700 Series LoadersThe launch of the new 700 Series <strong>com</strong>pact loadersadds three new models to the <strong>com</strong>pany’snew generation range. The new loaders, allwith vertical lift path design, offer several newfeatures and enhancements that extend therange of applications for <strong>com</strong>pact loaders.The 700 Series <strong>com</strong>prises a new skidsteerloader model, the S770, a new <strong>com</strong>pacttracked loader, the T770, and a new all-wheelsteerloader, the A770. The 700 Series loadersare part of a new large frame platformthat fits between the extendedmedium 600 Series and extendedlarge frame 800 Series loaders introducedin 2010. All three loaders offer higher ratedoperating capacities and increased engine andhydraulic power, allowing users to take on moredemanding applications.The S770 loader has an operating weightof 4.16t, a rated operating capacity of 1.57tand a tipping load of 3.14t. The rated operatingcapacity and tipping load for the T770 <strong>com</strong>pacttracked loader are 1.6t and 4.6t respectively.The T770 loader has an operating weight of4.7t. The A770 loader has an operating weightof 4.3t a rated operating capacity of 1.55t anda tipping load of 3.1t.As well as higher performance and power, thenew 700 Series loaders offer improved visibility,<strong>com</strong>fort and uptime protection. All three modelshave a height of 2.065m, a length with bucket of3.6m and a bucket hinge pin height of 3.35m.The S770 and A770 have a width without bucketof 1.83m <strong>com</strong>pared to a width over the tracksfor the T770 of 1.98m.www.bobcat.eu
