ABSTRACT A lifting jack comprises a support which is pivotally mounted at the lower end thereof to a base for rotation relative thereto, and at a central section thereof to a supporting arm also for rotation with respect thereto. The supporting arm has a free end which is adjustable in height by way of a crank operated spindle. The supporting arm defines bearing surface of spherical segment shape. A tiltable load carrying device has a base shaped to overlie the bearing surfaces of the supporting arm. The load carrying device defines a channel, open from above, which extends parallel to the axis of rotation of the supporting arm for engaging from underneath the vehicle to be lifted. The connection of the load carrying device to the supporting arm is of the ball-joint type. Indeed, the load carrying device has at its underside a supporting lug in the form of a spherical segment. The free end of the supporting arm is provided with a socket which mates with the supporting lug. An opening is defined in a middle portion of the socket with a connecting pin extending downwards from the supporting lug. The cross-section of the connecting pin in smaller than that of the opening. The connecting pin has at its lower end which protrudes from the socket an abutment which abuts against the underside of the socket. Therefore, when the supporting arm is raised by way of the spindle, the ball-joint type connection between the supporting arm and the load carrying device allows the latter to tilt to compensate the displacement of the supporting arm and of the vehicle.
