ABSTRACT:
A low profile parallel railcar discharge adaptor is designed for connection between a discharge gate of a center discharge railroad hopper car and a pneumatic conveyor for unloading pulverulent and granular material, such as sugar and the like, from the car. The adaptor includes low profile, parallel double airlocks in a single housing mounted on a frame with an attached pair of main wheels, each of which is attached to a hydraulic jack. The frame includes members which perform the dual function of support and air passage, thus helping to minimize the profile height of the adaptor. A handle is connected to the adaptor frame, extending therefrom upward at an angle and terminating in a comfortable operating position. A pair of drive motors and a corresponding pair of gear housings are attached to the handle, with each drive motor and gear driving a respective one of the rotary airlocks via an angled universal joint. A control for the hydraulic jacks is located on the handle proximate a handle grip.
