With the help of these two automobile lift components we have the ability to elevate an automobile.

In order to elevate an automobile in situations such as to change a tire or rise out of sand or mud etc. is now achieved by using a hand held jack, which all automobiles have. In order to correctly and safely use a jack to elevate an automobile we must first : a) have knowledge of how to use it b) have skill and experience in order to place it correctly especially when used on ground with a slope c) substantial muscle strength while working d) enough time which sometimes is precious. Finally we must take into consideration the possible soiling of hands and clothes from the parts of the jack which are covered with grease.

For all these reasons the use of a classic jack today results in an unpleasant problem for many people who seek easy and simple solutions having safety in mind.

This invention has the intention of improving the disadvantages above. One needs to do nothing more than adjust properly the wrench (1) (figure 1) or function the electromotor. Without any effort and avoiding contact with any other part of the system we can achieve the elevation of the vehicle safely even on grounds with a slope. All this is done quickly and effortlessly.

Figure (1) shows one of the two parts which compose the motor oper- ated part of the car lift. The circular motion of the removable wrench (1) is transmitted by the cone shaped toothed wheel (8) to the specially shaped section (9) of the screw movement (2) which brings about itself conic teeth. From there this circular motion changes to a straight up down movement with the help of the screw movement (2) which is a spiral trape-zoid and the screw nut (3) which work together resulting in the elevating or lowering of the automobile.

The screw nut (3) is situated stably with the two rods with rectangular dimensions (4) which end up in the special footing (5) which has the ability to circle around its central support in a way

that it is able to stabilize a car high with safety-even-on grouniis-with a slope.

The rods (4) move up and down as the lifting or lowering of the automobile in to specially designed cavities of the shell of the lift system.

The screw movement (2) is supported steadily on the shell of the mechanism (6) by two simple ball bearing axial disk shaped moving base.

In figure (2) it shows one of the two identical parts which composes the electric version of the car lift The circular motion of the exit axle of the electric motor (1) is transferred directly to the motion screw~ (2) ~ which has a spiral trapezoid and with the help of the screw nut (3) and rods (4) the circular motion changes to a straight up down movement resulting in the elevating or lowing of the vehicle.

The screw nut (3) is situated stably with the two rods with rectangular dimensions (4) which end up in the special footing (5) which has the ability to circle around its central support in a way that is able to stabilize a car high with safety even on grounds with a slope.

The rods (4) move up and down as the lifting or lowering of the auto- mobile in two specially designed cavities of the shell of the lift system.
