ABSTRACT:
A portable clamping device is provided which is quickly and easily attachable to the axle of a vehicle. The clamping devices provides a base upon which a lifting device can be positioned for lifting a wheel to be installed or removed from a vehicle relative to the vehicle axle. The device comprises a longitudinally extending base that can be installed on an axle through the central hole in a wheel to be affixed to the axle. The base includes several sets of guides for guiding a cable slidably attached to the base during the clamping operation. One set of guides extends transversely from the base while a second set of guides defines a longitudinal path along the base. The cable is positioned by the guides such that an arcuate segment of the cable in contact with the first set of guides extends in a plane transverse to the base. A linear segment of the cable in contact with the second set of guides extends along a longitudinal path on the base. A cable retracting device is provided on the base for reversibly retracting the cable segment extending along the base. In response to retraction of the linear segment, the arcuate segment progressively engages the axle of the vehicle, thereby clamping the vehicle axle. The lifting device positioned on the secured clamping device can than be employed to lift a wheel to be installed on the vehicle relative to the vehicle axis and to align wheel fastening elements on the vehicle hub with the wheel.
