Abstract
A wireless portable vehicle lift system. The lift system includes two or more portable lifts and an electronic control system for controlling the lifts. The electronic control system comprises a wireless communication system for wirelessly communicating lift control signals among the lifts. The electronic control system includes a remote control module configured to communicate wirelessly with the lifts, with the remote control module including a touch screen display. The electronic control system is programmed so that vertical shifting of the lifts requires dual operator input from at least two locations on the remote control module, with at least one of the two locations being on the touch screen display.
