铰接式运输汽车从矿岩运输的经济性考虑,大型露天采矿场一般宜采用载重60t 以上的刚性车架运输汽车。但在新露天矿剥离表土初期或采掘期较短、采矿范围有限或很不规则时,适于刚性车架汽车、路面和维护均良好的运输路的修建不一定可行,这种汽车的性能可能受 Articulated transport vehicles From the economic considerations of ore transport, large opencast mining sites should generally adopt the rigid frame transport vehicles over 60t load. However, the construction of transport roads suitable for rigid frame cars, pavements and maintenance may not be feasible at the early stage of new surface mine stripping of topsoil or with a relatively short excavation period and limited or irregular mining range. The performance of such vehicles may By
