Inner and outer wall coverings are secured to the corrugated side walls of the container and a laminate ceiling structure is secured to the interior surface of the container roof. A roof cap having a configuration corresponding to the roof of the container is mounted on the roof of the container, and the floor of the container provides a subflooring for the finished flooring of the building.

Abstract: A rear wheel suspension system for straddle carriers wherein a pair of axle mount plates are positioned on each side of the rear end of the carrier frame and each being swingably mounted on a transverse axis trunnion secured to a depending box beam on the straddle carrier frame. Rear wheel axle assemblies for pairs of tandem rear wheels are carried by the medial portions of the axle mount plates. Air springs and shock absorbers are interconnected bewteen the axle mount plates and the carrier frame.

Abstract: To simplify, lighten and reduce the cost of the rear wheel suspension on straddle carriers while increasing the operational efficiency of the suspension, a longitudinal walking beam is swingably mounted at its center on a transverse axis trunnion secured to a sturdy depending box beam on the straddle carrier frame. Rear wheel axle assemblies for pairs of tandem rear wheels are carried by the forward and rear ends of the walking beam. Shock struts are interconnected between the forward and rear ends of the walking beam and sturdy holders on the interior of the depending box beam in upwardly converging relationship for efficient operation. The shock struts can be hydraulic, air operated or mechanical with coil springs and cables.
