Abstract: A self-propelled material conveying system capable of traversing a surface along an elongated path. The conveying system includes a plurality of framework members arranged in tandem on the surface to form an elongated conveyor train. A connector on each framework member cooperates with a connector on an adjacent framework member for coupling the plurality of framework members and also permitting universal-type movement between adjacent members. The framework members also include supports for a plurality of orbitally-moveable crawler chains which engage the surface. The crawler chain supports substantially the entire longitudinal extent of the train. The framework members also support an orbitally-moveable conveyor belt above the crawler chains. The conveying run of the orbitally-moveable conveyor belt operates to convey material throughout substantially the entire longitudinal extent of the conveyor train.

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.

Abstract: A material transporting system is disclosed. The material transport system includes a self-propelled material conveying system which is capable of traversing a surface along an elongated path which has a curvillinear portion. This system also includes a plurality of framework members arranged in tandem on the surface which lies along a portion of the elongated path. Each of the plurality of framework members is connected by connector means on each framework member cooperable with connector means on each adjacent framework member. Each connector means permits universal-type movement between adjacent framework members. The framework members include means for supporting an orbitally movable crawler chain in engagement with the surface. The crawler chain is designed to extend throughout the longitudinal extent of the train. Each of the framework members has means for supporting an orbitally movable conveyor belt above the orbitaly movable crawler chain.

Abstract: An elongated conveyor having conveying and return traverses formed by an endless conveying element orbitally movable through a closed horizontally extending loop, the length and direction of which may be varied.
