ABSTRACT OF THE DISCLOSURE An elongated main beam is provided with support wheels at its opposite ends and a parallelogram-type lift arm assembly is pivotally mounted from a first end of the main beam for swinging movement between a lowered substantially horizontal position closely overlying the central portion of the main beam and an inclined position in which a lifting head carried by the upper end of the lift arm assembly may be used to support one side of a vehicle in an elevated position. A slide or follower is mounted on the second end of the main beam and a fluid motor is operatively connected between the main beam and the slide for forcibly shifting the latter along the main beam toward the first end thereof. Force arm struc- ture is pivotally connected between the follower and a midlength portion of the lift arm assembly and is operative to raise the lift arm assembly to a vehicle elevating position responsive to actuation of the fluid motor to force the follower along the main beam toward the first end thereof.
