1. The machine can clean and distribute the ballast during the track maintenance and overhaul.
2. In combination with the material transportation wagon, the machine can realize four working functions including ballast cleaning, ballast supplementing, ballast distributing and new ballast replacing.
3. The machine can also be used to collect the dirty and polluted ballast and throw them to one side of the line or deliver them to the material transportation vehicle by the conveying appliance.
4. The machine is driven through four axles and is featured in low or high speed running function.
5. The machine can distribute new ballast transported from the materials transportation wagon to the track bed simultaneously when backfilling the screened clean ballast to the track bed.
