ABSTRACT:
A material conveying system capable of traversing a surface along an elongated path having at least one curvilinear portion. The conveyor structure includes a plurality of framework members arranged in tandem on the surface of the elongated path. There are connectors on each framework member which are cooperable with connectors on each adjacent framework member for coupling the plurality of framework members to form the train. Each framework member has a series of rails to support an upper and lower run of an orbitally moveable crawler chain which engages the surface and which chain is capable of propelling the conveyor along the surface. At least some of the framework members include support structure for supporting an orbitally moveable conveying belt above the orbitally moveable crawler chain. The conveying run of the orbitally moveable conveying belt is operable to convey material substantially throughout the entire longitudinal extent of the conveyor train either while the train is moving or is stationary.
