Mechanical or electric lifting system for automobile

The lifting of a car can be achieved simply by two identical mechanisms each of which uses a motion screw (2). These two mechanisms are independent from each other and are located on both left and right sides of the car. The motion is transferred by a crank handle or by an electric motor. The circular motion is changed into lifting or lowering movement with the help of the motion screw (2) and of a screw nut (3).
