A self-synchronizing wheel lift system configured to lift a vehicle using compressed air. The lift system comprises a plurality of pneumatic wheel lifts and a lift control system. The lift control system is configured to automatically synchronize the heights of the wheel lifts during vehicle lifting without causing any of the wheel lifts to completely stop during vehicle lifting.

Pneumatic wheel lift synchronization

A wheel lift system capable of performing an electronically synchronized lift using two or more individual lifts. In one embodiment, the wheel lift system is pneumatically powered via an external source of compressed air, and the system is electronically controlled from a common control station/module. The common control station/module can include a moveable cart and/or a wireless handheld control module. In one embodiment, each lift of the wheel lift system is connected to a common movable cart and a user control interface is also connected, either physically or wirelessly, to the movable cart.
