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 RS64 Ramp is a “roll-up” loading ramp that can be used to load all work equipment that is normally transported on a flat car. It can load both rail bound and rubber tired machines. Rubber tired and most rail bound machines can climb the 7% slope with ease. A winch is provided for disabled machines or machines that do not have sufficient traction to climb the ramp slope. One man can extend or retract the ramp in under 5 minutes using a remote pushbutton control.
Weight: The ramp adds 13,000 pounds (5900 kg) to the weight of a flat car.
Construction: Welded from tubular steel. Tread bearing areas are made from wear resistant steel.
Engine: Air cooled diesel Deutz F2L2011 30 hp (22.4 kw) @3000rpm.
Winch: Equipped with 5/8 (16 mm) inch wire rope. Retrieval speeds: 12 (3.66 m) feet per minute/high speed; 7 (2.13 m) feet per minute/low speed. Maximum tension: 20,000 pounds (9072 kg).
Hydraulic System: A gear pump is driven directly by the engine providing hydraulic power to the ramp control circuit. Filters protect the ramp circuits from contamination. A pendant with pushbuttons is used to energize a solenoid directional valve that cycles the ramp.
Electrical System: 12 volt dc negative ground. Maintained by an engine driven 40 amp alternator. Equipped with a special coiled plate 56 amp hour battery. Color coded and numbered wiring.
Loading Capacity: The ramp can support 40,000 pounds (18144 kg) per axle on rail bound machines and 30,000 pounds (13608 kg) per axle on rubber tired machines.
Capacities: Fuel: 11.5 gal. (43.5 l), Hydraulic: 25 gal. (94.6 l).
Options: Adjustable wheel chocks, turnbuckle tie downs, bridging bar systems to allow movement of machines from one flat car to another.
