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® RS70 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 19,500 lbs. to the weight of a flat car.
Construction: Welded from tubular steel. Tread bearing areas are made from wear resistant steel.
Engine: Liquid cooled diesel Cat® C1.7 31 hp (23.1 kw) @ 2800 rpm
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 lbs. (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 85 amp alternator. Equipped with a special coiled plate 50 amp hour. 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.
