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: An axle suspension assembly for vehicles has a trailing arm which is connected to the axle by means of a locator plate that is welded to the axle housing and heat shrunk on to the arm, the plate and the clamping pad that engages the opposite side of the arm having relieved faces that serve to minimize localized stress concentrations during high load conditions.

Abstract: A cargo container formed of extruded light metal framing members and cooperating panels is made in subassemblies composed of parts which are secured together primarily by riveting, the subassemblies also being secured to one another primarily by riveting, although certain key fastenings are made by welding, and parts are limitedly telescopable prior to welding, to accommodate variations resulting from manufacturing tolerances.Fastening means for securing cargo within the container, and for securing the container against displacement in a vehicle during transportation, are integrated with rigid framing elements.

Abstract: The disclosure relates to the configuration and method of fabrication of the forward underbody of a semitrailer. A lower plate of the underbody has two inverted channels welded thereto. A kingpin extends downwardly through an aperture in the lower plate and is welded in position between the two inverted channels. The kingpin and the channels are braced by laterally spaced gussets which are welded in position thereto. A top plate with angular edge flanges fills the space between the inverted channels, the edge engaging sloping corners of the channels and forming a right angle therwith. Continuous welds secure the top plate to the channels which are below the top surface thereof. The assembly thus provided is extremely strong, light in weight, and capable of assembly with conventional welding equipment and without need of repositioning the several elements during the assembly and welding process. Critical welds are spaced from the high stress areas of the secured elements.
