ABSTRACT:
A coordinated lift system with user selectable RF channels coordinates the raising and lowering of a vehicle relative to a surface by using wireless communications. The lift system includes at least two lift mechanisms each having support frame, including a post, a carriage, an actuating device, and a control device with a channel selector switch. The carriage is slidably mounted on the post and is configured to support a portion of the vehicle. The actuating device is engaged between the support frame and the carriage and is activated to move the carriage relative to the post. The control device is interfaced with the actuating device and includes an RF transceiver to enable communication by RF signals with the other control device. The channel on which the transceiver operates is user selectable in the field. A rechargeable battery may provide power to the control device to allow for increased mobility of the lift system.
