دردشة على الإنترنت Read More2019-6-22 Mining trucks, also referred to as haul trucks or road trucks, are used to haul (transport) the ore or waste material from the loader to the dumpsite. In most cases, these vary from 36 tons to 315 tons. The size and cost of operating mining trucks are directly proportional to its tray capacity, while the speed at which the truck can travel is inversely proportional to its capacity. As with loaders, the variety of truck types differs according to their reliability, maintenance requirements, productivity and operating cost. The mine environment greatly affects the performance of a truck. For example, “rimpull" affects the forward motion of the truck. Rimpull is the natural resistance of the ground to the torque of the tyre, and is equal to the product of the torque of the wheel axle and the wheel radius. Manufacturers supply pre-determined rimpull curves for their trucks to enable a satisfactory calculation of truck cycle times. The rimpull curves delineate the increase in road resistance as the truck
