Title: Lift device and pneumatic actuator therefor

Abstract: A wheel lift device includes an upright extending upwardly from a wheeled base. A carriage slides along the upright and includes a wheel support to support an automotive wheel thereon. A pneumatic lift mechanism is housed in the upright and is coupled to the carriage. A lift control comprises a supply valve to couple the lift mechanism to a source of compressed gas for lifting and a vent valve to couple the lift mechanism to a vent for lowering. The lift device has rapid response, is of low cost and requires minimal maintenance when arranged to connect to conventional compressed air supply lines of the type readily available in automotive servicing stations. Location of the lift controls directly on the upright ensures quick access for controlling the lifting and lowering of wheels in direct proximity to the task being performed.
