Abstract
An actuating system for operating the doors of a railroad hopper car. A plurality of levers for each hopper operate to rotate the doors of the hopper between an open and a closed position. The mechanism applies a tension force, rather than a compressive force, to push the doors closed. The mechanism also provides an over center latch to positively close each door. The mechanism may be used on either single or double hopper doors.
