Abstract
Radial stacking or stockpiling conveyors are utilized to transport material into stockpiles, storage bins, or other places of storage or placement. The conveyor of the invention has a conveyor frame and an undercarriage that supports the frame and includes a front push arm and a rear push arm and a wheel assembly. The front end of the conveyor frame can be raised and lowered, and the conveyor frame can be swung slowly about the pivot point at the tail end of the conveyor, travelling on the wheel assembly along an arcuate path. To facilitate raising and lowering of the conveyor frame while maintaining a constant pivot radius of travel, a curved cam slot is provided on the conveyor frame through which the top of the rear push arm travels as the conveyor frame is raised and lowered.
