The payload capacity of trucks used in any materials handling operation has a significant effect on the overall materials handling cost per tonne. For an existing facility considering upgrading their mining trucks, the potential benefits of moving higher volumes of material has to be weighed against the possibility that the infrastructure the trucks use may have to be upgraded. Mining trucks today are designed to carry much larger loads and more commonly have a rear dumping action. These are now being used for coal hauling as well as overburden stripping, whereas previously, bottom dump trucks were used for coal hauling.
