Abstract
A system for changing the chucks of a tire uniformity machine includes a control which inactivates the main machine hydraulic and electrical system. The control also activates the chuck changing system which includes a small hydraulic power unit and a low set pressure relief valve for raising and lowering the lower chuck assembly and a small gearmotor for rotating the upper chuck assembly to facilitate removal of the upper chuck. The small hydraulic power unit and gearmotor, while mounted on the tire uniformity machine, operate entirely independently thereof for safety purposes.
