Abstract
Jack with an erect component in the form of a leg (1) that rests against the ground (4) and of a foot (2) articulated thereto and with a vehicle-lifting arm (6) that pivots around a fixed horizontal axis on the leg. The arm can be directly or indirectly raised or lowered away from and toward the ground by means of a spindle (7). The arm is provided with a fixed or pivoting vehicle-supporting component at its free end. At the other end, which engages the leg, the arm is provided with appropriate controls that displace a slide (10) along the leg such that the lower end (19) of the slide can come to rest against the leg-supporting surface (3) of the foot. The object is a lighter-weight jack that will be just as sturdy. A stop (21) is accordingly positioned on top of the leg-supporting surface and facing the slide's lower end.
