Abstract: A swivel deck loading and off loading system for flatcars. The system is mounted onto a flatbed railcar and works in conjunction with the railroad loading/off loading area for the safe and efficient loading/off loading of transported equipment, such as trailers, from either side of the rail car. The system uses a structured ramp platform, which is affixed to the top flange of a slew ring bearing. The slew ring bearing lower flange is affixed to a mounting plate. This mounting plate is affixed to the bed of the rail car. The ramp platform swivels freely and is supported on a polyethylene sheet, which is affixed to the bed of the rail car. This arrangement operates such that it allows the platform to freely rotate without binding when under load. A forklift is used to lift the front of trailers so that the trailers can be loaded/unloaded from the flatcar.
