The benefits of the new Mach 4™ mobile column lift from Rotary Lift can be summed up in two words: fast and easy. Some of the design features making the Mach 4 up to 30 percent faster overall include horseshoe wiring, adjustable forks, spring-loaded handles, and the ability to operate the lift from any column. The Mach 4 is sold in sets of four or six battery-operated columns.
