- TITLE JAM MACHINE, RAILWAY CONVEYOR OF WORKS AND OPERATING PROCEDURE OF SUCH CONVOY
- the invention relates in particular to the laying, maintenance or repair work of a railway track. It relates more specifically to so-called tamping operations, which consist in making the tamping tools penetrate the ballast in the interval between the sleepers of the railway, in order to mechanically compact the ballast under the sleepers.
- Tamping machines are usually integrated into work trains, which include several vehicles hitched to each other, to carry out successive operations necessary for the laying, repair or replacement of the railway track.
- Such a work convoy is intended to advance continuously at low speed on the railway track, without stopping, and preferably at a constant working speed, each train machine having to perform these functions specific to this working speed.
- the tamping operation requires that the part of the tamping machine which supports the tamping tools remains stationary relative to the railway track for the time necessary for the tamping tools to penetrate into the ballast between two successive sleepers. the track, to the generation of a vibratory movement of the tamping tools in the ballast, then to the retraction of the tamping tools out of the ballast.
