ABSTRACT:
An airlift railcar discharge adaptor is designed for connection to a railroad car discharge opening for unloading pulverulent and granular material from the car. The adaptor includes a discharge chute and a discharge inlet mounted with a pair of wheels providing support and mobility. The wheels can be swiveled to allow precise maneuvering of the adaptor. A horizontally oriented rectangular discharge inlet connects with the chute and is adapted to be connected to the discharge outlet of the railroad car. A handle is connected to the adaptor. Each wheel is connected to a respective bell crank, which is, in turn, connected to a respective pneumatically operated cylinder. Each pneumatic cylinder is connected to an independent lever control conveniently positioned proximate the adaptor handle. The adaptor can be raised and lowered by manipulating the levers, each of which is connected to a three-way valve for charging the associated pneumatic cylinder. The adaptor can be moved, maneuvered, raised and lowered by a single workman from a standing position.
