Kershaw 12-12 Tie Crane


Progress Rail’s Maintenance-of-Way (MOW) division was born out of the movement toward mechanization in the railroad industry and introduced the fi rst 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.

The Kershaw 12-12 Tie Crane is designed to perform safe, effi cient tie handling operations. The Model 12-12 has a maximum lifting capacity of 1200 pounds at 24 feet from the center of the track. The upper deck and tie grapple are capable of 360 degrees of continuous rotation. The machine can be fi tted with several grapple confi gurations including basket grapples, single tie grapples, two-tie grapples, timber grapples, and others. The boom can also be fi tted with an electro-magnet for the retrieval of tie plates or with a flail type mower head for brush removal.
