Abstract
An improved railroad car loader/unloader apparatus includes a backhoe-type machine adapted to operate atop an open top railroad car. The apparatus includes front and rear support feet and a center support beam to which are pivotally attached a pair of center support feet, one to either end of the center support beam with each of the feet contacting an upper surface of the sidewalls of the railroad car. Each center support foot is pivotable through a horizontal plane between extended support position and a retracted, stored position. In one alternative version, double action hydraulic piston and cylinder units are provided to selectively extend and retract the center support feet.
