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 conveyor support frame comprising a pair of elongate members extending substantially parallel to the cables, a plurality of transversely disposed conveyor support rollers, and structure for suspending the elongate members from the cables. An endless conveyor belt is mounted for movement around a course defined by the conveyor support rollers of the conveyor support frame 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. An axially outwardly directed force is applied to the ends of the conveyor system to suspend the system from the receiving zone to the discharge zone. Structure is provided for varying the tension on the conveyor belt in relation to the loading on the belt. 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.
