ABSTRACT:
An integrated treadway cargo handling system comprising a plurality of treadway panels suitable for converting an aircraft from passenger use to cargo use is disclosed. The treadway panels include inboard and outboard panels arrayed in spaced rows and columns on the deck of the aircraft. The rows are spaced from, and attached to, one another by panel restraint bars that are affixed to seat tracks located in the deck of the aircraft. The inboard treadway panels support retractable inboard guide rail, vertical restraint and roller assemblies, and the outboard treadway panels support outboard guide rail, longitudinal-vertical restraint and roller assemblies. In addition, adjacent edges of the inboard and outboard treadway panels support flip-up rollers. Further, tie down rings, also affixed to the seat tracks, are located in apertures in the treadway panels. Also, side load tie down brackets form part of the panel restraint bars. Finally, invertible casters and rollers are housed in the panels located at the forward end of the aircraft. The retractable nature of the guide rail and roller assemblies, the flip-up rollers and the invertible casters and rollers allow the aircraft to transport either rolling stock entirely, cargo pallets entirely, or a mixture of rolling stock and cargo pallets.
