AN increase in haul truck rolling resistance has been found to have a significant triple effect on costs, according to a recent study. Research by Western Australian School of Mines professor Dr Rodger Thompson showed that fuel burn, plant damage and cycling times all suffer at the hands of a poor haul road surface. He found three factors of a failing or uneven haul road sent operational costs up. Firstly, the energy required to ‘climb’ the weight out of each depression in the road was adding up to 5pc in fuel costs; secondly, the increased cycling of suspension and friction on tyres was accelerating truck maintenance; and lastly, the cycle times were suffering badly. The study found that the addition...

SELECTING the right boom is essential to getting the job done right. Before selecting the boom system, the needs of both operators and maintenance personnel should be taken into consideration as they are often overlooked during initial design. When positioning the boom system, thought should be given as to where an operator might be able to safely stand, out of reach of the boom, to ensure a clear view of the work area. By properly positioning an operator viewing platform, or an operator cabin, the risk of operator injury can be eliminated. Similarly, by considering and making provision for suitable maintenance park locations with tool and rockbreaker change frames, changing rockbreaker tools and rockbreaker removal for servicing can be done...
