A lifting and loading device for the disabled is movable on casters mounted on a U shaped base. A pair of lifting bars form a supporting fork, mounted at right angles to the base, are vertically jackable from the base. The supporting fork is raised or lowered with a crank operated mechanical jack. A seating pad for use under the disabled person in a wheel chair or car seat is connected to the elevating fork by straps which hook to the lifting bars. The fork provides additional support to the disabled person by being positioned at chest level. The entire apparatus is assembled of stacked components, which are held together by gravity, and may be easily assembled and disassembled for ready movement and storage.
