Redundant systems assure the lifts’ safety. Self-setting wedge locks backup their holding brakes. Synchronizing controls backup their naturally synchronous operation. Locomotives remain level and under the operator’s control at all times.

With 69 inches of lift height, the lifts can raise mine locomotives high enough for personnel to work comfortably beneath them. They can be stopped at any convenient location within normal travel to accommodate individual needs. Their mechanical ball screw lifting mechanisms provide an inching capability that enables the lifts to aid in the replacement of components that are installed from below.

Frictionless and virtually maintenance free, the ball screw is the premier design used in mobile column lifts. In addition to an extended service life and an inching capability, the ball screw enables the lifts to be lowered without power. Seldom needed, this capability eliminates the potential for locomotives to become stranded on the lifts due to a power failure or malfunction.

Electrically operated, the lifts can be cable connected or wireless. Wireless lifts are battery powered and radio controlled. Cabled lifts operate on three-phase power and have interconnecting cables between columns. The choice of battery or three-phase power is dependent upon local conditions. Batteries used in the lifts are the deep cycle type and can make up to twenty-five full capacity lifts on a single charge.

In shops where space is at a premium, mobile lifts are particularly advantageous. Unlike pits, they do not require a dedicated bay. They can be rolled into position when needed and stored out of the way when not in use.
