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 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.


The Kershaw® 12-12 Tie Crane has a maximum lifting capacity of 1200 lbs. (544 kg) at 25 ft. (7315 mm) from the center of the track. The upper deck and tie grapple are capable of 360° continuous rotation. Recent enhancements include Tier IV engines, redesigned upper and lower decks, enhancements to better accommodate hydraulic hosing and wiring and hydrostatic propel. Hydraulic brakes are offered as an option, eliminating the pneumatic system if desired.
