Abstract: An insulated vehicle body, such as a refrigerated truck or trailer, has load carrying reinforcement beams in the roof structure with bottom slots accessible through openings in the ceiling skin to receive removable hangers that may be used to suspend meat rails or other articles from the roof structure.

Abstract: The disclosure relates to a load bearing, post-free sidewall for an over-the-road trailer or the like. A bottom rail of the sidewall is attached to the floor of the trailer and secures the sidewall thereto. Each of the sidewalls comprises a pair of substantially parallel, vertically extending, horizontally spaced and load bearing plastic panels having foam insulation disposed therebetween. The bottom rail member transfers loads thereon substantially equally to each of the panels of each sidewall.

Abstract: The disclosure relates to a meat rail support system for refrigerator trailers having post-free, foam-filled walls. An outer top rail of the trailer side wall is secured to the outer skin of the side wall. An inwardly extending flange is positioned above the side wall and is either integral with the top rail or riveted thereto for the acceptance of a meat rail support beam.In one embodiment, an inner side wall top rail of low heat conducting material, for example, FRP plastic, is secured to a plastic inner skin of the side wall and has an outwardly extending flange positioned above the wall. A meat rail support beam extends transversely across the trailer and rests on the flanges of the inner and outer top rails. Fastening means are located between the inner and outer skins of the side wall so as to transfer loads on the meat rail support beam relatively equally to both the inner and outer side wall skins.
