Each column of Rotary Lift’s Wireless Mach 4 mobile column lift is powered by batteries and communicates with the other columns wirelessly. Operated using the easy-to-use control panel on any of the columns, the Wireless Mach 4 is available in sets of four or six 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, and the lifts come equipped with back-up communication cables to use 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.
