  • Wheel lift rotator
    Patent number: 5513938
    Abstract: The present invention is directed to an apparatus for use in a paint booth to facilitate the coating of an object such as a wheel or rim with a liquid, powder, or other coating. The apparatus is designed to rotate a wheel about both its horizontal and vertical axes. In this manner, the wheel may be more easily and uniformly coated with a minimum of effort by a paint booth operator. After the wheel is coated, the apparatus is designed to lift the object above the work surface so that it can be connected to an overhead conveyor system that may be provided to remove the wheel from the paint booth.
