ABSTRACT:
An access and support apparatus for loading and unloading gondola railroad cars using a crane-type crawler, which system includes a trailer-mounted ramp for disposition in close proximity to a gondola railroad car and multiple pallets adapted for spanning the top width of the gondola railroad car and supporting tile crane-type crawler. The crane-type crawler is unloaded from the trailer and traverses the ramp to the pallets. In a first preferred embodiment the pallets are characterized by fixed pallets having no adjustable feature. In a second preferred embodiment the pallets are adjustable to accommodate a characteristic bulge in the center of the gondola railroad cars for a higher degree of safety. The pallets are typically sequentially moved from the rear to the front of the crane-type crawler as the crawler loads or unloads tile gondola railroad cars and traverses the length of the cars.
