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 removable 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. Alternative versions of the center and front support feet include support rollers for enhanced movement. A movable front bucket support stop block enhances the conversion of the apparatus between railroad car loading/unloading operations and other uses.
