The S-1400M Universal Truck Frame Lift is a fast action, longer reach air lift jack that is specially engineered to meet the requirements of heavy-duty equipment shops. The 48 Inch between the cylinder and the lift pads, lets you reach under the vehicle and lift by the frame - the safest way! Anywhere an air hose will reach, you have low-cost lifting power with one-man portability. The two larger center wheels allow the S-1400M to maneuver for easy positioning. Trigger the dual action valve to raise or lower up to 7 tons.
