Abstract
The invention is a wheel jack having a cradle for a wheel. The cradle has a first surface and a second surface. The second surface is spaced from the first surface to form a wheel space. An actuator moves the first surface relative to the second surface along a horizontal direction to lift or lower the wheel in the cradle.
