The Mach 4 mobile column lift from Rotary Lift is sold in sets of four or six battery-operated columns. Set up allows users to form a horseshoe shape with wiring, leaving the front or back of the lift free of wires. Each column has a rated capacity of 18,000 lbs. The lift can raise a vehicle 70" in just 78 seconds, and can be used to service vehicles from classes 1 through 8. Each Mach 4 column can be used anywhere in the shop - including wash bays - as well as outside. Its hydraulic cylinder is positioned to protect its chrome piston rod from debris and damage at all times.
