  • Patent number: 6561742
    Abstract: A railroad car loader/unloader apparatus includes a mobile machine adapted to operate atop an open top rail car. The apparatus includes a plurality of support subassemblies with surfaces adapted to engage upper surfaces of sidewalls of the rail car when the apparatus is positioned thereon. The support subassemblies are removable. The apparatus also includes a boom structure with a bucket attached at an end thereof. The apparatus can move atop the rail car on its own power, or by coordinated use of the boom structure to push or pull the apparatus along the rail car. In an alternative embodiment, rollers are attached to the support subassemblies in a position to engage the sidewall's upper surface to reduce travel friction.
