<p>This is a lightweight jack of the type known as "Y" jacks, for use with vehicles. It is made of aluminium, and thus its basic components can be of lesser thickness, particularly the arm (2) and the body of the device (1). The 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 is fitted, the body of the device (2) has lateral reinforcements in the shape of vertical ribs at 90 degrees; the support base controls the body's passage to the interior of the device, and there is an internal reinforcement device (20) between the shaft (9) of the gripper (7) and the bar shaft, to reduce the thickness of the arm (1). <IMAGE></p> |
