Document Type and Number:
WIPO Patent Application WO/2022/119939
Kind Code:
A3
Abstract:
A jacking tie and method of using a jacking tie to level and/or lift a railroad track. The jacking tie is configured with an elongate body that is configured to span beneath two parallel rails of a railroad track. Preferably the jacking tie is of the configuration to replace a standard railroad tie. The jacking tie has two jacks that are positioned so as to lift each of the parallel rails of the railroads. A track support shell is supported by the hydraulic cylinder jacks. The track support shell is configured for nesting or mating engagement with the lower body shell in a compressed or resting position. The hydraulic jack cylinders are configured to lift the track support shell away from the lower body shell, thus lifting the rail positioned above the hydraulic jack cylinder. The track support shell and lower body shell are pivotally connected such that the ends of the track support shell can be independently raised.
