An insulated and logistics track construction for the side and end walls of a refrigerated vehicle includes an exterior metal sheet attached to a plurality of vertical posts that are horizontally spaced. An interior sheet of fiber reinforced plastic (FRP) is spaced from the exterior sheet and attached to the vertical posts by a logistics track attached to each post with the FRP interior sheet captured between the logistics track and post. The logistics track is shorter than the posts, thereby leaving portions of the FRP interior sheet above and below the logistics tracks unattached and unrestrained by the posts. A mandrel with vertical tubes is positioned adjacent the FRP interior sheet while foam is introduced between the exterior sheet and the interior sheet and the pressure of the foam forces the FRP interior sheet to create a flat inner surface between the vertically extending logistics tracks with the logistics tracks recessed below the flat inner surface and to create a corrugated shape in the surface of the FRP interior sheet above and below the logistics tracks.

Wall and logistics track construction for a refrigerated vehicle

A road vehicle for hauling cargo has a substantially rectangular flatbed member with front and rear upright walls. The front wall is attached to the flatbed by a semi-rigid joint and the rear wall is attached to the flatbed by a free swinging hinged joint. One or more longitudinal members extend between the top of the front and rear walls. Posts spaced longitudinally of the cargo vehicle extend from the elevated longitudinal member or members to the flatbed member. One or more of the posts are collapsible or swingable to be selectively movable to a position for unobstructed access for side loading and unloading of the vehicle.

An insulated door for a refrigeration vehicle includes spaced walls between which there is an insulation material. Hardware such as hinges and latches are mounted to the door by fastening the hardware to a rigid support mounted on the outside wall of the door, and providing openings in the support for accommodating fastening elements whereby the hardware is affixed to the support and the fastening elements do not thereby penetrate through the door walls.

Mounting for hardware on an insulated trailer door

A semi-trailer is provided with a pair of laterally spaced drop-leg assemblies operated by a tubular cross shaft mounted on the trailer frame. These drop-leg assemblies are widely spaced and are positioned near the side boundaries of the frame. A jaw member is mounted to turn on the frame at a location forward of the drop-leg assemblies and has an open-ended channel to accept the king pin on the truck. A pair of cables each having one end attached to the jaw member each contact the drum surface and extend partially around the cross shaft in opposite directions. Adjustable means are provided for securing one end of each cable to the cross shaft so that turning movement of the jaw member causes corresponding turning movement of the cross shaft. One end of one of the cables is pivotally attached to the jaw member to compensate for limited arcuate length of the drum occasioned by presence of the open-ended channel to receive the king pin. Each drop-leg assembly includes a gravity-actuated support leg movable to one of three extended positions and each support leg is retracted by means of a chain operated by the cross shaft.
