MAINTENANCE TIPS FROM EQUIPMENT MANUFACTURERS AND OUR READERS Equipment to keep you up and running Welding generator features power increased productivity Miller Electric Mfg Co s Big Blue 450 Duo CST is a dual operator diesel enginedriven welding generator that features two CST 280 stick TIG inverters and 12000 watts of continuous three phase power in a single unit The unit provides increased productivity by allowing two welders to work off the same machine with two separate welding outputs The machine offers performance on difficult stick electrodes found in structural steel and fabrication applications as well as performance for pipe fabrication and maintenance applications The Tier 4icompliant machine operates at 1800 RPM which reduces fuel use and keeps noise levels up to 10 dBa quieter than other models improving worksite communication and safety according to the company www millerwelds com Compound repairs protects in wear and abrasion applications DFense Blok wearing compound from ITW Devcon is formulated to outperform and outlast traditional epoxy wear and abrasion products even in the most severe impact and sliding abrasion conditions the company says DFense Blok is an alumina ceramic beadfilled epoxy compound that when used with DFense Blok surface wetting agent increases drop impact strength over 1 in ceramic tile DFense Blok is ideal for use in repairing rebuilding and protecting typical wear and abrasion applications such as pipe elbows scrubbers ash handling systems cyclones fan blades pump boxes float cells screw conveyors and augers etc It can also be used in place of abrasion resistant metal and ceramic tile www devcon com New grease range meets challenging conditions Shell Lubricants launched a new improved range of Shell Gadus greases Shell Gadus is the new unifying name for Shell greases The range is designed to meet the challenges of the biggest fastest and largest equipment in operation today in some of the wettest coldest hottest and most extreme conditions The range of products has been developed to deliver value through enhanced wear protection long grease life and increased system efficiency the company says www shell com High performance grease ideal for conveyors industrial applications DayLube high performance grease from Dayton Progress uses nanoceramic particles which act as sub microscopic ball bearings to provide continuous lubrication to steel surfaces and is suited for use with conveyors With a much lower coefficient of friction at all temperatures than traditional PTFE greases chemically inert DayLube is also environmentally friendly the company says It maintains its viscosity across a full temperature range and the grease does not soften or run out the company adds DayLube provides friction reduction and wear resistance making it ideal for a wide range of industrial applications DayLube is also proven on bushings cables cams chains gears lifters machine parts robotics slides wear plates and more www daytonprogress com 68 PIT QUARRY December 2011 www pitandquarry com
