ABSTRACT:
A wheel lift device for raising and supporting a wheeled vehicle such as an automobile, by engagement with a vehicle wheel thereof includes a lower support frame, casters, a carriage for engagement with the vehicle wheel, support struts connecting the carriage to the support frame and maintaining the carriage substantially parallel to a floor, and a mechanism for raising and lowering the carriage with respect to the support frame. The support frame and carriage engage the wheel by approaching the wheel along its path of roll, i.e. from a front or rear end of the vehicle. During this engagement, portions of the wheel lift device extend parallel to and on opposite sides of the wheel to lift the wheel and vehicle from a position where the vehicle is standing on a floor. A vehicle supported by the subject wheel lift devices in engagement with each wheel is readily adjusted for wheel alignment.
