MOBILE TRACK-TREATING MACHINE FOR REMOVING, CLEANING AND REINTRODUCING BALLAST WITH A BALLAST COMPACTING DEVICE

摘要

The travelling railway maintenance machine is partic. for ballast-cleaning, having an extraction and conveyor chain for the ballast from below the rails and delivering to a sieve mechanism, also a return mechanism for the cleaned ballast to the area after the chain and below the rails and sleepers. A transverse compactor beam below them is fixed at the ends to supporting uprights coupled to a drive mechanism. The compactor mechanism (16), comprising a plate-type beam (37), is situated directly in or in front of the path of the discharged ballast. The drive (38), coupled to the uprights (33), generates a continuous reciprocating movement in the plane of the rails. This initially compacts the ballast away from the working direction.
