Rotary Lift’s new Wireless Mach 4 mobile column lift does away with cords and cables. Each column is powered by batteries and communicates with the other columns wirelessly. As a result, technicians no longer have to worry about knocking the lift out of service by running over the cords or getting one hooked on a bumper. Technicians can operate the entire lift using the patent-pending control panel on any of the columns. The wireless system can be retrofitted to existing Mach 4 lifts.
