Abstract

A process is described for hauling a loaded motorized dump truck up an untracked incline typically found in mining situations. The process makes use of the momentum of an unloaded dump truck to facilitate the hauling of the loaded truck. In one form of the invention, the two trucks are coupled. In another form, the energy generated by the unloaded truck as it moves down, is stored and used to help raise a loaded truck.
