QS-1200II full section cleaning machine is mainly used for overhaul and cleaning the ballast track. The machine is designed to dig out, without the removal of track skeletons, the ballast under the track skeleton by means of the motion of its excavation chain, and it allows the ballast dug out to be screened by its vibrating screen. The dirt will be conveyed to the two sides of the railway or back to the material conveyor truck, while the clean ballast be evenly backfilled over the whole section of railway track. For defective track sections, the machine can completely clean the polluted ballast.

The QS-1200II full section ballast cleaning machine is divided into three parts: screening truck (including front-powered truck, screening truck), excavation truck and rear-powered truck.

The machine is equipped with advanced track measuring system. It automatically controls the ballast backfilling by detecting the track status, ensuring that the track after cleaning is approximately in line with the original track condition and effectively reducing subsequent mechanical workload.

After the computer control system sets the excavation depth, it is only necessary to control the working speed so as to perform automatic cleaning operation. This machine can ensure that there is no piled ballast at the beginning of cleaning and the ballast is right enough after cleaning.

The machine has adopted advanced screening technology to improve screening efficiency. The rear material conveyor truck can make up for lacked ballast after cleaning or complete excavating.

A dust removal system is provided in the excavation area, the screening area and the conveyor belt area to reduce dust pollution and improve the working and surrounding environment.

The QS-1200II full section ballast cleaning machine is by far the most suitable ballast undercutting cleaning machine with the highest production efficiency, the highest degree of automation and the best backfilling effect.
