Abstract: This is an articulated jack with two pairs of arms, connecting at one end with a nut (11) and at the other with a bar (12). Both these are in turn connected by a spindle worked by a crank winding handle. The other ends of the arms rotate around a base (1) and a gripping device (2.about.. The outer arms (3, 4) and inner arms (5, 6) are in turn connected by auxiliary parts (18). The actual size of the jack has been considerably reduced.

Abstract: A lightweight vehicle jack of the "Y" type includes aluminum, particularly in the arm (2) and the central body of the device (1). A gripping device (7) provides a larger surface area to take the edge of the body of the vehicle. On the side to which the nut (4) is fitted, the body of the device (2) has lateral reinforcing vertical ribs at 90 degrees, and there is an L-shaped internal reinforcement device (20) between the gripper (7) pivot and the pivot of the shaft of the bar (5), to reduce the thickness of the arm (1). The support base controls the body's passage to the interior of the jack.
