  • Lifting systems for use with vehicles
    Publication number: 20030091418
    Abstract: A lifting system is attached to the rear of a pick-up truck and has a load carrying platform which can be raised and lowered between the tray of the truck and the ground to assist loading and unloading. The platform is raised and lowered by operation of a cable system incorporated within a frame. The frame and platform structure can be pivoted to a stowed position in which the platform structure then acts as a tailgate for the vehicle. The frame and the platform structure are foldable to a reduced depth configuration so that when in the stowed configuration the height of the frame and platform structure then approximates to the height of the sides of the truck.
