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.
