Trucks

Abstract

Trucks designed exclusively for off-highway use are the principal equipment for material transport in surface mines. Large and efficient off-highway trucks make possible the development of large low-grade ore and coal deposits. These deposits, with high stripping ratios and large quantities of both waste and ore or coal, are minable because of the economies of scale achieved with large off-highway trucks. Due to greater truck capacity and the resultant increased capital and operating costs, it has become increasingly important to analyze haulage requirements.
