Kershaw 12-12 Bridge Crane


Progress Rail’s Maintenance-of-Way (MOW) division was born out of the movement toward mechanization in the railroad industry and introduced the first Kershaw Ballast Regulator in 1945.

Today, Progress Rail supplies Kershaw MOW equipment, providing machines to all Class I railroads, transit and short lines and contractors around the world.

Our Kershaw Model 12-12 Bridge Crane has a maximum lifting capacity of 1,200 pounds (544 kg) at 24 feet (7315 mm) from the center of track. The upper deck and tie grapple are capable of 360-degree continuous rotation. It can handle bridge ties, caps, stringers and other bridge components.
