  • Pneumatic wheel lift synchronization
    Patent number: 10457532
    Abstract: 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.

  • RAM RETRACT SYSTEM FOR A LIFT
    Publication number: 20180194602
    Abstract: A lift for raising and lowering items, such as vehicles. The lift comprises a lifting assembly including a cylinder and a ram configured to extend from and retract within the cylinder. The lift additionally includes an air-storage reservoir configured to store pressurized air received from an external air source. The air-storage reservoir is fluidly connected to the lifting assembly, such that the air-storage reservoir is configured to cause the ram to retract within the cylinder even when the lift is not connected to the external air source.

  • Electronically controlled wheel lift system
    Patent number: 9580284
    Abstract: 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.
