The present invention concerns a housing (1) for the transportation of a cargo, such as truck trailers, housings mounted on the chassis of a truck, or shipping containers. The housing of the present invention comprises: (a) walls (1R) defining a closed inner space (1i), (b) an opening (2) provided in one of the walls, and further comprises a rigid door comprising one or more rigid panels (3) which are movable to seal or unseal said opening (2); (c) a flexible fast door comprising a motorized driving mechanism (10) suitable for moving a leading edge (4L) of a flexible shutter (4), wherein the flexible shutter (4) comprises two lateral edges engaged in parallel guiding rails (7) fixed to two parallel and opposite edges of the opening (2), wherein the rigid panel (3) and/or the parallel edge of the opening (2) is provided with a groove to accommodate the guiding rails (7).

This invention is a retractable cargo wall for flatbed trucks and trailers that lowers into an enclosure that may be rollup canister or tray. Once the cargo walls are lowered, the posts supporting the walls may collapse into the bed, thereby transforming a bed with cargo walls into a flatbed. It is also anticipate that a truck or trailer bed with posts can be transformed into a flatbed truck or trailer.
