Compaction of ballast layer in the tie cribs
Keywords. Liner-tamper machines, compaction of ballast layer in the tie cribs and shoulders of ballast sections, increasing quality of railway.
Summary. Nowadays in Russia ballast layer in the tie cribs aren’t compactioned. Result of this is decreasing of railway quality after liner-tamper works. For increasing quality of railway, it is necessary to compact ballast layer in the tie cribs. Analysis of printed publications and patent literature connected with machines for compacting ballast layer in the tie cribs and shoulders of ballast sections, shows what engineering solutions have disadvantages. In chair of lifting, road-building machines and equipment of PGUPS was developed apparatus for compacting ballast layer in the tie cribs, provide good quality compaction and high reliability.
