World record for raiseboring - Atlas Copco

MARKETPLACE >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>Here’s Omega– a good bit betterUSA Atlas Copco Secoroc has introduceda new sealed bearing tricone drill bit forrotary drilling. Called Omega, the bit isdescribed as a “technological leap forward”over standard air-bearing roller cone bits.High precision machining to close tolerances,innovative seal technology, premiumlubricants and proprietary materials andprocesses have resulted in premium performancebits with superior service life andcost savings.These sealed bearing bits are madewith extremely smooth bearing contactsurfaces. A patented outer “excluder” ringkeeps contamination from cuttings, gritand water out of the bearings under virtuallyall circumstances, while an inner sealretains grease in the bearings to lubricatethe bearing elements.Excellent penetration rates and bit lifehave been achieved during fields tests incoal and copper mining in both Australiaand the USA.The new Omega bit: Providing vastly superiorperformance in rotary drilling compared withconventional air-bearing bits.New names makethe ROC choice easierWORLD Atlas Copco’s ROC crawler rigshave been given new names to make iteasier to distinguish between the variousmodels and their different characteristics.The range has four categories: AirROC,PowerROC, FlexiROC and SmartROC. The AirROC series consists of pneumaticand manually operated drill rigs,easy to operate with simplicity in designand a robust steel structure. The PowerROC series consists ofhydraulic drill rigs with a straightforwarddesign and trouble-free hydraulics. The FlexiROC series consists of hightechnology rigs with a medium level ofsophistication. The SmartROC series consists of hightechnology rigs with a high level of sophisticationand equipped with the latestoptional equipment to minimize costsin each drilling and blasting operation.Tophammer, DTH and COPROD drillingmethods are used right across therange and this is evident from the productdesignations such as FlexiROC T30 Rwhere “T” stands for tophammer.Bo-Göran Johansson, Vice President,Marketing at Atlas Copco’s SurfaceDrilling Equipment Division explains:“Several rigs in the range have similarbasic technical specifications such as drillmethod, hole range, installed power andflushing capacity for specific applications,but there are also various control systemsthat meet basic requirements for differentlevels of technical capability.“The new structure makes it easier todistinguish between the models and easierto understand the advantages that eachcategory has to offer. It also better definesthe segment and application for which eachrig is intended.”>>>>> IN BRIEF >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>Atlas Copco at WTC 2011Atlas Copco will be a “Gold Sponsor”at the World Tunnel Congress inHelsinki, Finland, May 20–26. Thetheme is “Underground Spaces inthe Service of a Sustainable Society”. Atlas Copcowill present two papers: “Setting Up The New HighQuality Standards For Pre-grouting Drilling In Tunneling”and ”Opportunities To Optimize ProjectEconomies Through Integration Of Digital Drillingand Blasting Technologies”.Robbins goes yellowAtlas Copco Robbins raiseboring machines, a leading namein the raiseboring industry since the 1960s, are now allinstantly recognizable. Previously produced in white, thesepopular machines are now manufactured with the samedistinct yellow and gray design that characterizes all AtlasCopco products. This new design “language” is intended toconvey robustness, serviceability and sustainability, whichdescribes the strengths of the Atlas Copco range. Robbinsraisedrills were introduced in 1962 and incorporated intothe Atlas Copco Group in 1994.True colors: A new AtlasCopco Robbins 91RH Craiseborerwith the newdesign inyellow andgray.30 MINING & CONSTRUCTION – 1 / 2011
