近年来,采矿生产需要的柴油价格上涨和供应极不可靠对于采矿工业越来越成为至关重要的因素。解决燃油供应和价格问题的一个途径就是柴油电动轮卡车采用架线供电。架线辅助装置主要包括把电从架空线路直接输给电动轮卡车的轮马达(Wheel motors)。架线辅助装置有四大主要优点:可减少柴油燃料消耗;增加生产率;改善露天矿深采运
In recent years, the rising price of diesel oil and the unreliable supply of supplies for mining production have increasingly become a crucial factor for the mining industry. One way to solve the problem of fuel supply and price is to use diesel-powered electric trucks with overhead power supply. The overhead aids mainly consist of Wheel motors that supply electricity directly from the overhead lines to the electric wheel truck. The overhead aids have four major advantages: Reduced diesel fuel consumption; Increased productivity; Improved open pit mining
