Rotary Lift’s Wireless Mach 4 mobile column lift does away with cords and cables as each column is powered by batteries and communicates with the other columns wirelessly. This reduces trip hazards and makes lift set-up easier. The lift is operated using the easy-to-use control panel on any of the columns. Wireless Mach 4 is available in sets of 4 or 6 columns and can be used anywhere in the shop, as well as outside. Each column has a rated lifting capacity of 18,000 lbs. Lifting and lowering of all columns is automatically synchronized. The lifts are equipped with back-up communication cables that can be used in place of the wireless system with the flip of a switch. The wireless system can be retrofitted to existing Mach 4 mobile column lifts.
