ABSTRACT:
A car dumping apparatus intended for open top railway cars or other containers which are moved sequentially through a supporting frame and are rotated upwardly and to one side about a single horizontal axis to discharge the contents onto a dumping area located on one side. A first hydraulic piston motor rotates the frame and railroad car as a combination about the horizontal axis. Thereafter a second hydraulic piston motor advances the combination of frame, railroad car, an intermediate support member and the first hydraulic piston motor, as a combination, about the same horizontal axis until the open top of the railroad car confronts the dumping area whereby the contents of the railway car are spilled onto the dumping area. Economies of construction and operation are achieved as a result of the rotation about a single horizontal axis. A preferred embodiment recognizes and exploits the fact that the frame and railroad car combination has a higher centroid level when the railroad car is loaded than when the railroad car is empty. This relocation of the centroid axis permits the final upward movement of the railroad car and frame to be powered by gravity and permits the return movement of the frame and empty railroad car to be accomplished through gravity. As a consequence, it is not necessary to employ double acting hydraulic piston motors in many installations. In those installations where double acting hydraulic piston motors might be included in a design, such double acting hydraulic piston motors can be normally operated as single acting hydraulic piston motors with accompanying savings in operating expense.
