The present invention is a system for high capacity hydraulic truck loading. The system includes a frame to which a hydraulic cylinder is pivotably at a first cylinder pivot. The hydraulic cylinder, when actuated, applies a force to an L-shaped primary arm at a second cylinder pivot. This force cause the primary arm to pivot around various pivot points in a linkage assembly made up of the frame, a U-shaped secondary arm and a plurality of stabilizer arms. The respective positions of the connecting pivots and linkages allow the primary arm to raise or lower an item for loading without contacting a truck tailgate or bumper.
