Abstract
A re-railing unit for re-railing a derailed rail car comprises a base, two stabilizer rams located at opposite ends of the base, and a port plate slidably mounted on the base. The support plate carries a pair of vertical lifting rams from which is suspended a vertical lifting arm. The bottom of the lifting arm is hook-shaped to engage the underside of a rail car drawhead. The lifting arm raises an end of the rail car in response to extension of the lifting rams. A shifting ram then slides the support plate across the base to reposition the rail car wheels over the track. The lifting arm is lowered to enable the wheels to rest upon the track.
Claims5
A re-railing unit for re-railing a de-railed rail car, comprising:
- a base having longitudinally spaced ends and connecting arm means releasably connectible to a vehicle;
- hydraulic ground support members carried adjacent respective ends of said base and including vertically adjustable means;
- a support plate mounted on said base for longitudinal sliding movement thereon;
- bearing means, including a plurality of rolling elements disposed between said support plate and said base;
- a pair of upright hydraulic lifting rams extending upwardly from said support plate;
- a lifting arm suspended at its upper end from said lifting rams and disposed between said lifting rams, a lower end of said lifting arm carrying hook means for engaging a drawhead of the de-railed rail car, said lifting arm and drawhead being raisable in response to extension of said lifting rams;
- power actuated means connected between said base and said support plate for sliding said support plate longitudinally across said base to reposition wheels of the raised rail car over the track from which it has become de-railed so that the wheels can be lowered by said lifting rams.
