Machine and method for dynamically balancing rotatable shafts featuring positioning and welding equipment that is controlled by an electronic control unit that determines the imbalance of a rotating shaft and the amount of weight required at predetermined balance planes associated with misalignment joints of the shaft. The positioning and welding equipment is moved along a rail of the machine parallel with the shaft mounted therein into precision points and the welding gun moves into a welding position in which the shaft is griped by the welder and the correction weight is welded at the correction point on the shaft in the correction plane. In a second embodiment, balancing is achieved by removing calculated amount of materials at points on the shaft determined by the electronic control unit.

Rotatable shaft balancing machine and method with automatic flexible shaft balancing equipment

A vehicle wheel support device for use in a wheel alignment assembly including a floating plate assembly movably supported relative to the base upon which a vehicle is positioned. The floating plate assembly includes a pair of rollers disposed in a fixed non-parallel orientation with respect to each other. The floating plate assembly is movably positioned such that a vehicle wheel may be located between the pair of rollers to isolate the vehicle wheel from the base so as to stabilize all forces acting thereon and wherein the rollers rotate the wheel so that various wheel alignment parameters may be measured.
