Abstract

See full text

According to some embodiments, a railcar comprises an underframe and at least one hopper. The hopper is configured to transport a lading material. A longitudinal sliding gate assembly is coupled to the hopper and comprises: a pair of side walls coupled to a pair of end walls forming a discharge opening; a pair of tracks, one coupled to each end wall; a sliding gate slidably coupled to the pair of tracks; and a threaded drive screw coupled to the sliding gate and to the pair of side walls. Rotation of the threaded drive screw in a first direction moves the sliding gate along the tracks to an open position that permits the lading material to discharge, and rotation of the threaded drive screw in an opposite direction moves the sliding gate along the tracks to a closed position that restricts the lading material from discharging.
