METHOD AND TRACK MAINTENANCE MACHINE FOR TREATMENT OF A BALLAST TRACK

The invention relates to a method for treatment of a ballast track by means of track maintenance machine which comprises a lifting unit, having gripping rollers for gripping a track grid formed of rails and sleepers and lifting drives for lifting the track grid, and a measuring system for comparing to a target position of the track, wherein the lifting unit is set in vibration by means of a vibration exciter and the vibration is transmitted to the track grid, wherein the lifting unit is controlled by means of a control device in such a way that, during a lifting operation, the lifting unit is set in vibration, and the track grid is first lifted to above the target position and subsequently lowered to the target position. By means of the method according to the invention it is possible to carry out in a simple manner a lifting of the track grid with simultaneous stabilization of the track position.

Method and track maintenance machine for correction of track position errors

A method for the correction of vertical position error of a track by a track tamping machine and a dynamic track stabilizer. Starting from a registered actual position, an over-lift value is prescribed for a treated track location with which the track is lifted into a preliminary over-lift track position and tamped. The track is subsequently lowered by dynamic stabilization into a resulting final track position. In this, a smoothed actual position course is formed from a course of the actual track position, wherein an over-lift value is prescribed for the treated track location in dependence of the course of the actual track position with regard to the smoothed actual position course. In this way, only short-wave track faults are treated with an over-lift value.

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.

Track-lifting and ballast-spreading apparatus

A rail-lifting and ballast-spreading apparatus that may be employed to rehabilitate damaged tracks or aid rough in of new tracks, is described. The apparatus includes a track-lifting unit at a forward end thereof that includes an arm that is pivotable to extend forwardly and over a section of track in need of repair or ballast replenishment. Rail clamps are provided on a distal end of the arm that engage and travel along the rails as the apparatus moves forward. A conveyor provides a stream of ballast across the width of the tracks while the tracks are lifted and as the apparatus moves forward onto the now repaired tracks. A surge bin is provided to increase a rate of distribution of the ballast material by the conveyor over that available from the ballast-delivery consist.
