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.

Dependent claims

A movable wheeled apparatus supporting an elevatable platform for use in transferring freight between a truck and the ground level or any intermediate loading dock height;

said apparatus including a base frame structure with a plurality of wheels for moving said structure on a generally horizontal base and a plurality of screw jacks for resting and stabilizing said wheeled structure on a nonmovable base, said elevatable platform being movable in a vertical direction by pairs of lifting arms powered by hydraulic means, said platform being operatively connected by hinge means to two oppositely directed access ramps, one of which is long in the direction perpendicular to said platform and narrow in the cross direction, and the other ramp is short in the direction perpendicular to said platform, both said ramps having short vertical curbs along their lateral edges to guard against freight-carrying trucks running off the edges of said ramps.
