Martin Engineering introduces patented conveyor belt cleaner
Terex Trucks will launch its new Generation 10 TA300 and TA400 articulated dump trucks ( ADTs ) in South Africa in the first quarter of 2017 . With fuel-efficient Scania engines , the trucks excel in large-scale construction projects , quarries , and mine sites . The TA400 is the largest Generation 10 ADT . Advancements include improved cab sealing , heating and ventilation ; improved hydraulic system via magnetic suction filters to protect against environmental contamination ; improved durability on the sealed , force-cooled multidisc brakes standard on all three axles ; a new generation transfer box ; and Allison transmission with fifth generation automatic adaptive shifting . Improved hood design enables easier maintenance access and enhanced headlamp illumination .
Sandvik Mining and Rock Technology will showcase equipment and services at CONEXPO-CON / AGG in Las Vegas in March , in application areas including rock drilling ; rock cutting ; crushing and screening ; loading and hauling ; tunnelling ; quarrying ; and breaking and demolition . Among the equipment on display will be the new CS550 cone crusher for second-stage crushing ; the new QJ341 + mobile jaw crusher with double-deck pre-screen for fines removal ; the electrically driven UI310 + wheeled impact crusher designed for the aggregates industry ; the new QE441 Free Flow mobile scalper for screening products with high moisture contents ; and the Pantera DP1100i surface drill rigs with redesigned control system and updated user interface and touch screen .
Caterpillar is developing autonomous mining truck technology for an expanded range of models , including other brands , driven by mining companies ’ goal of reducing mining costs using existing fleets . According to the company , retrofitting technology is a proven means for mining companies to get the most from their assets , as many mining companies operate mixed fleets . Developing autonomous systems for other brands of trucks will enable the company to offer a total solution to these customers . The autonomous arrangement of the 363-tonne payload capacity 797F — the largest of the Cat line — is being tested , and other models evaluated . Several currently operating Cat 793F trucks have also been retrofitted to operate autonomously .
Martin Engineering introduces patented conveyor belt cleaner
US based Martin Engineering has patented a conveyor belt cleaner — the Martin QB1 Cleaner HD — designed to last longer and reduce total ownership cost .
The QB1 HD frame is roll formed out of a single piece of steel , and a special alignment system facilitates precise installation . A square mainframe is positioned to shed dust and spillage , and the urethane blade formulation can accommodate belt speeds of up to 4.6m / sec and service temperatures of -40 – 70 ° C .
The cleaner features Martin Engineering ’ s unique CARP ( constant angle radial pressure ) technology to maintain the most efficient cleaning angle throughout service life , with a no-tool replacement process that can be performed safely by one person in under five minutes .
“ We ’ ve simplified the manufacturing process and also re-engineered the blade itself ,” explained Paul Harrison , director of the Conveyor Products Business Group . “ The new profile is less complex to produce , and because it can be roll formed or manufactured on a press brake , it will be easier to source throughout the world from any Martin Engineering manufacturing site .”
The QB1 HD can be retrofitted onto any existing Martin Engineering tensioners , and most competitive systems . It is available in lengths of 457 – 2 438mm and can also be ordered in 3.05m sections for increased versatility .
The product announcement comes on the heels of Martin Engineering ’ s introduction of the company ’ s ‘ Forever guarantee ’, which ensures lifetime no-cost replacement of tensioners and main frames for any belt cleaner assemblies that are exclusively fitted with the company ’ s replacement blades . The cleaner is covered by the company ’ s Mr Blade programme , which provides fresh , factory direct replacement blades , delivered and custom-fitted on-site — installed free of charge .
