of operation such as the torque generated. “This also makes it possible to become much more accurate when specifying components like drive motors – where we can specify size and capacity in a more scientific way,” states Mayhew-Ridgers. “We might find, for instance, that a smaller motor will start the motion just as well as a larger unit allowing a saving on capital costs and energy consumed.” The test frame can also be used to test different condition monitoring solutions, by installing the necessary tools and con- ducting computer monitoring; even the performance of newly developed isola- tors under the machine can be tested with results escalated to suppliers about how their items could be further enhanced for better results. He says the company’s compact design of a dual motor base – where the motor base can stand on a pedestal between two machines and drive them both – also makes it easier for a mine’s process plant to

New rigid dump truck tyres from Goodyear Goodyear is introducing the RM-4B+ OffThe Road (OTR) tyre range for rigid dump trucks in the Europe, Middle East and Africa (EMEA) region. After successful performance in the United States, the brand-newOTR range, which includes several new sizes – among them a 63-inch version which was recently presented at the MINExpo in Las Vegas – is now available to customers in EMEA. The range comprises five sizes for vehicles operating in severe conditions such as those typically encountered in min- ing and quarrying. The Goodyear RM-4B+ range features 170-level tread depth and optimal tread zone stiffness for excellent wear performance. The innovative CycleMax tread rubber compound ensures cool running and is enhanced by tread lug blading for additional heat resistance. Heat resistance is also a benefit of the centreline chan- nel, which gives added lateral traction.

Other tread features include interlocking blading for high sta- bility and angled main grooves for forward and lateral traction. Particularly important for severe operating conditions are the extra thick sidewalls, which provide excellent protection against friction and impact. “Our new RM-4B+ OTR tyres feature our latest technologies in materials, design, con- struction and manufacturing. Thanks to this they provide high performance in all areas resulting in a high number of operating hours and therefore reduced costs per hour to our customers,” said Tracy Maclear, Marketing & Brand Manager, Goodyear South Africa. The tyres are all tubeless radials with load capacities from 12 150 kg up to 63 000 kg. Goodyear South Africa, tel (+27 41) 994-6911
