Lower arms are suitably linked to a base, with the upper arms suitably linked with respective lower arms. One of the upper arms is longer than the other of the upper arms, with the longer arm being provided with a movable support at a free end thereof, in turn having a device for fitting into or against an object to be lifted, such as an automobile. Furthermore, a support linkage is suitably secured between the movable support and the shorter upper arm.
