ABSTRACT:
An apparatus for the loading and unloading of railroad boxcars includes a first platform assembly that abuts the boxcar and a second platform assembly that abuts the first platform assembly and is secured thereto. The height of the first platform assembly is adjustable proximate the boxcar. The height of the second platform corresponds to that of a tractor-trailer's floor. A ramp allows a forklift to drive up onto and down off of the two platforms. Safety rails prevent the forklift from driving off of any raised portion of the apparatus. A trailer intermediate plate allows the forklift to pass onto the floor of the tractor-trailer and an intermediate plate allows the forklift to pass onto the floor of the boxcar. The apparatus includes three main component parts (the first and the second platform and the ramp) that are each adapted for lifting and movement by the forklift. The apparatus is portable for temporary use where desired, can be disassembled, moved, and used elsewhere.
