Abstract:
A lift-type loading platform system for mounting on a motor vehicle, said system comprising:a lifting and closing mechanism including two supporting frames extending substantially parallel and spaced a predetermined distance apart,a loading platform for raising and lowering a load and for closing off a cargo compartment of the vehicle,a single hydraulic lifting cylinder mechanism for raising and lowering the platform, anda single hydraulic closing cylinder mechanism for swinging the loading platform back and forth between a horizontal position and vertical position, said single hydraulic closing cylinder mechanism being spaced from said single hydraulic lifting mechanism,said lifting and closing mechanism also including said lifting cylinder mechanism having force application points lying in a first plane formed by pivot points of elements of a first supporting frame of said two supporting frames, said lifting cylinder mechanism being associated with said first supporting frame and exerting forces on said first supporting frame to raise and lower the platform, and said closing cylinder mechanism including force application points lying in a second plane formed by pivot points of elements of a second supporting frame of said two supporting frames, said closing cylinder mechanism being associated with said second supporting frame and exerting forces on said second supporting frame to swing the loading platform back and forth between a horizontal position and a vertical position.
