ABSTRACT:
An aerial conveyor system comprises a pair of spaced apart cables extending from a first vehicle including material delivery apparatus across a material receiving zone, across an open area, and across a material discharge zone to a second vehicle. The cables support a plurality of conveyor support frames each comprising a pair of tubular members extending substantially parallel to the cables, a plurality of hook rollers for supporting the tubular members on the cables, and a plurality of transversely disposed conveyor support rollers. An endless conveyor belt is mounted for movement around a course defined by the conveyor support rollers of the conveyor support frames and functions to transport material received from the delivery apparatus of the first vehicle in the receiving zone across the open area to the discharge zone. The conveyor is driven by apparatus including a drive roller mounted at the discharge zone end of the conveyor support frame which is actuated by hydraulic fluid supplied through the tubular elongate members thereof.
In the use of the aerial conveyor system, overburden is preferably removed in accordance with a series of vertically stacked zones. The aerial conveyor system is then employed to discharge the excavated material into a previously mined portion of the excavation in accordance with the same vertical sequence. By this means the original vertical configuration of the excavation is restored, thereby facilitating return of the mined area to productive usage.
