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.
Claims7
A method of mining an open cut mine so as to provide for transfer of mined material from the open cut mine to the top of a trackless incline adjacent thereto, comprising the steps of:
- (i) attaching a line member to a first unloaded motorized vehicle supported by ground engaging wheels at the top of the incline;
- (ii) attaching said line member to a second motorized vehicle, said second motorized vehicle being loaded with mined material and supported by ground engaging wheels at the bottom of said incline;
- (iii) hauling the loaded motorized vehicle using its motive power up to the top of the incline and assisting said hauling by lowering of said first unloaded motorized vehicle from the top of said incline down the incline;
- and
- (iv) loading said first motorized vehicle with mined material at the bottom of said incline;
- and
- (v) unloading the second motorized vehicle at the top of said incline.
A method of mining an open cut mine so as to provide for transfer of mined material from the open cut mine to the top of a trackless incline adjacent thereto, comprising the steps of:
- (i) storing electrical energy in a motor generator set by movement of a first motorized vehicle supported by ground engaging wheels down the trackless incline, said first vehicle being attached to a first line member associated with said motor generator set;
- (ii) attaching a second line member to a second motorized vehicle loaded with mined material and supported by ground engaging wheels at the bottom of the incline;
- (iii) supporting said second line member with pulleys located along the length of the incline;
- (iv) assisting in hauling said second motorized vehicle using its motive power up the incline by a power winch actuated by said stored electrical energy by pulling on said second line member;
- and
- (v) unloading said second motorized vehicle at the top of the incline.

- (iii) hauling the loaded motorized vehicle using its motive power up the incline and assisting said hauling by lowering of said first motorized vehicle from the top of said incline down the incline;
- (iv) detaching both vehicles from the line member;
- (v) unloading the second motorized vehicle at an unloading point near the top of said incline, and
- (vi) travelling the first motorized vehicle to a loading station adjacent an excavation site.
