Our lifting jack has a double piston. This is necessary, since the trailer has for instance the three-way clearance of a car. The second piston drives out only if the first one is in his end position.
Therefore comfortable working without additional support (on solid ground) and in one step is ensured. Above is an thread-adjustable admission, which fits exactly under the body of axle. Also the wheel nut key is telescopic extendable. Thus you open easily wheel bolts even if they are strong fastened.
