  • Patent number: 6615478
    Abstract: A chassis inverter consisting of a set of clamps that hold a mobile vehicle chassis and a hydraulic driven rotary actuator. The apparatus and an overhead crane system provide a method of inverting and transferring chassis in a short time period needed to meet high volume vehicle manufacturing needs. The apparatus consists of two c-shaped clamps that cradle the chassis. The clamps are assembled to a shaft that is driven by a hydraulic cylinder through a sprocket and chain arrangement that provides a full inversion of the chassis. One clamp has a motorized trolley that provides adjustment needed for handling chassis of widely varying wheelbase. The process involves an overhead crane system with a bridge crane section that provides the necessary broadside loading motion, and an interlocking monorail section that allows the hoist carriers to exit the bridge and travel perpendicularly to the inverting apparatus' loading direction.
