Abstract
A conveyor apparatus transports materials along an incline. The apparatus includes an endless base conveyor belt that is tensioned between lower and upper end rollers and is aligned with the incline. A drive means drives the base belt at a selected speed and in a selected direction along the incline. An endless and freely hanging tension-less overhead conveyor belt is provided above the base belt, and has a substantially flat conveyance surface for conforming to and covering materials placed on the base belt. A drive roller of the tension-less overhead belt is coupled to the upper end roller of the base belt so as to drive the tension-less overhead belt at a speed and direction similar to that of the base belt.
