ABSTRACT:
Mined material, such as coal, is transported in a curvilinear path. An endless conveyor belt is mounted by a string of wheeled cars having upper and lower sets of rollers. The cars are positioned at a sharp turn connecting first and second paths extending between a mine bore and a remote area. The cars positioned at the sharp turn reorient the conveyor belt from a generally horizontal position to a generally vertical position and back to a generally horizontal position. The mined material is moved off the conveyor belt before reorientation, at a location between the sharp turn and the mine bore. The cars have first and second sets of wheels with the frames pivotally connected between the wheels, for pivotal movement about an axis parallel to the axes of the wheels. Coupling elements connecting the cars together provide a universal joint action.
