RTJ002 Metro Rail Tunnel Designed For Cleaning Vehicle
This tunnel cleaning vehicle is a specialized engineering equipment purpose-designed and manufactured exclusively for the cleaning and maintenance of railway tunnel structures. It is capable of performing full-coverage, all-directional cleaning operations on the inner walls, floors, and auxiliary facilities of tunnels, effectively removing dust, dirt, and other attachments to ensure the cleanliness and operational safety of tunnel infrastructure.
As a high-end automated solution, it features an advanced integrated system that combines precision mechanical structures, sophisticated electrical control systems, and high-performance hydraulic technologies, embodying a high degree of intelligence and integration in tunnel maintenance equipment. The vehicle comprises a robust power car and a functional trailer, forming a complete operational unit.

- Maximum operating speed during cleaning operations: 5–10 km/h, which ensures stable and thorough cleaning performance across tunnel walls, ceilings and floors.
- Maximum transfer speed between job sites (non-cleaning mode): 80 km/h, compliant with standard railway line operation regulations, enabling efficient and flexible deployment between different tunnel sections or maintenance depots.
Efficiency improvement of tunnel cleaning vehicles relies on integrated optimization:
- Adopting stepless speed regulation and fully automatic operation to ensure continuity
- Upgrading water supply, spraying, brushing, and sewage recovery systems to reduce repeated passes
- Optimizing vehicle maneuverability and multi-degree-of-freedom cleaning mechanisms for full coverage in one pass
- Strengthening on-site logistical support and route planning to shorten auxiliary time
- Applying intelligent control and real-time monitoring to reduce manual intervention and unexpected downtime
- Coordination with maintenance window plans also ensures efficient use of available operation time
The safety of tunnel cleaning vehicles is ensured through a combination of inherent safety design, standardized operation, and emergency preparedness:
- The vehicle is equipped with anti-collision sensors, emergency brakes, safety interlocks, and explosion-proof electrical systems
- Pre-operation inspections, strict traffic control, and qualified personnel are enforced on-site
- Real-time monitoring of the environment and operation status
- Clear emergency plans and regular drills further guarantee safe operation within the approved maintenance window
