Abstract: A wheeled elevator apparatus for use in transferring freight between a highway truck and a freight storage dock or building, the apparatus including an elevatable platform powered by hydraulic cylinder means and including two oppositely directed ramps hingedly connected to said platform to provide access to said platform for pallet jacks moving pallets of freight, one of said ramps being long enough to reach inside the highway truck to form a bridge from the elevatable platform to the highway truck, the bridge having side curbs and being sufficiently narrow and laterally off-set to permit an independently operated roller, skate-wheel, or belt conveyer to function simultaneously beside the elevatable platform for moving small individual packages of freight between the same building or dock and the same truck.

Abstract: A wheeled elevator platform for use in loading and unloading highway trucks from and to a loading dock at a merchandise storage facility. The elevator includes folding ramps, hydraulically operated lifting arms to raise and lower the elevator platform, a plurality of screw jacks to level the platform, and bumpers to absorb the forces of a truck accidentally colliding with the apparatus.

Abstract: Mobile elevatable platform devices are fitted with an impact absorbing bumper, a truck restraining hook mechanism, and, optionally, a ground anchor.

Abstract: Wheeled elevator apparatus for use in loading and unloading freight into and out of a highway truck; the apparatus including a platform raised and lowered by hydraulic power engaging lever arms arranged in a parallelogram structure, drawbridge access ways from the platform to the truck bed and from the platform to the loading/unloading level, the access directions being perpendicular to each other, wheels for moving the apparatus from place to place, and jacks for securing the apparatus off its wheels.

Abstract: A system in which a self-propelled fork lift truck that is collapsible to a compact structure for storage is made transportable on a highway freight handling truck, by lifting itself into an enclosed bay of the highway truck, or onto a platform attached to the highway truck, or onto a trailer pulled by the highway truck.
