Abstract

See full text

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, preferably hydraulic cylinder jacks that are positioned so as to lift each of the parallel rails of the railroads. The jacking tie body has two sections. 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. Preferably, the pivotal connection is maintained in a slot allowing the pivotal connection to rise and lower when both hydraulic lift cylinders are raised or lowered. This functionality allows for the lifting and lowering of two parallel rails of a railroad track by allowing for the lifting of the track and replacement of ballast beneath the track. Preferably the jacking tie is constructed such that it can be left under the track or alternatively can be extended and left in place while the railroad is maintained in operation or alternatively while a ballast tamper travels along the track.
