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.
