QS-650 full section ballast cleaning 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 in front of the machine or back to the material conveyor truck, while the clean ballast will be backfilled into the railway median directly or backfilled into the ballast bed at the two sides of the steel track behind the excavation chain by means of its backfilling conveyor belt. Due to the even backfilling of ballast over the whole section of railway track, the machine can reduce the work quantity of track tamping. For track sections subject to slurry pumping, the machine also can perform complete cleaning of ballast.

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.

CQS-550 full section ballast turnout cleaning machine is suitable for cleaning work both in the turnout area and in the ballast bed of the main track. The machine can completely finish cleaning of a group of No.12 single-way turnouts (left or right) in 90 minutes. Due to the retractable mudsill and excavation chain storage mechanism, the mudsill and the excavation chain is not required to be removed when cleaning the turnout, thus greatly reducing the auxiliary working time, relieving the labor intensity and improving the working efficiency.

The CQS-550 full section ballast turnout cleaning machine has three ways to backfill the ballast after cleaning: through the left-side backfilling conveyor, the right-side backfilling conveyor and the middle backfilling hopper. The ballast amount backfilled through each way can be regulated by the ballast assigning mechanism to make uniform backfilling. The machine is equipped with working mechanism for complete cleaning of ballast and new ballast adding mechanism. After complete cleaning of ballast in the turnout area, the new ballast will be backfilled by the jointly marshaled material conveyor truck and the ballast adding mechanism of the machine in time. The screened mud will be thrown by a main mud conveyor or a rotary conveyor to one side of the railway or into a material logistics. The rotary can rotate towards left or right.

The CQS-550 full section ballast switch cleaning machine is equipped with a 8-line video monitoring system and the cabs at both sides are equipped with a colored display indicating the conditions of the front and rear lines in section operation and the operation condition of the main working mechanism in cleaning, making it convenient for observation and at the same time ensuring the safety of operator and device.

BS-550 ballast shoulder cleaning machine can collect dirt and ballast on shoulders at the entrance of the dug guide slot by complete machine working action, dug guide slots and ballast gathering plates. The ridgy ballast is driven by the excavation chain running at high speed and then falls into the mixed ballast conveyor belt through the dug guide slot. The dirty ballast is firstly sent into the screening device through the mixed ballast conveyor belt for screening, and then the clean ballast screened is assigned to the backfilling conveyor belts at the two sides by the ballast receiving hopper following by being backfilled to the rear of the dug areas; while the dirt is conveyed to the two sides of the railway or the material conveyor truck by the dirt conveyor belt and the rotary casting belt. The complete machine has characteristics of advanced technical performance, a simple structure, reliable quality and a comparatively high performance-price ratio.

BS-550 ballast shoulder cleaning machine features short auxiliary time for working, not destroying the original ballast bed structure and not affecting the traveling vehicle on the adjacent railway. Ballast shoulder cleaning can promote water permeability of the ballast bed, reduce damages to the ballast bed, extend the overhaul circle and relieve the labor intensity; in combination with cleaning under sleepers, the full section of the ballast bed can be cleaned once and for all, thus making the cleaning work more complete and effective and share a part of the work load of the ballast undercutting cleaning machine so as to improve the cleaning efficiency.
