ABSTRACT:
A device for mechanically connecting hopper car unloading boots to the discharge outlets on the car for unloading bulk material from the car, in which a pair of coupling frames are supported on a lift platform and interlinked with each other so that they can be spread apart into position under the outlets on the car and drawn together between the tracks by moving either one of the coupling frames, such movement automatically resulting in the other coupling frame being moved a corresponding amount in the opposite direction. In addition the lift platform is prevented from accidentally lowering out of engagement with the outlets by a hydraulic lock that is built into the lift cylinder.
