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.

 

Technical Details

 

• The large, totally enclosed cab has a capacity of 99.5 cubic feet. A wide front windshield allows unobstructed views of the boom operation through the full range of motion.

 

• Dual hydraulic drive motors provide quicker response and faster indexing at the job site. Each individual motor drives a single, 3-inch axle through #100 pound? roller chain. Both motors are accessible from ground level for easy of maintenance.

 

• Hydraulic manifold-type stack valves provide superior serviceability with easily replaced solenoids and cartridges. All valves are easily accessible on the upper deck.
