Patent

CA 2069729

A jack for railroad well cars has a frame comprising a central section which fits between the rails and the underside of the car frame. The central section spans the rails and extends somewhat beyond the sides of the car frame. The central frame section connects to a fixed, upright frame section at one end and a pivot section at the other end. The pivot section is movable between a horizontal setup position and a vertical operating position. A lifting beam is mounted on the frame and extends transversely to the car frame. Hydraulic actuators connected between the ends of the lifting beam and the frame are adapted to move the lifting beam between lowered and raised positions. A ratchet and pawl are provided on the upright and pivot frame sections to prevent unwanted lowering of the lifting beam.
