Subway Tunnel Trolley

As a professional manufacturer in China, Xinhuixing would like to provide you quality Subway Tunnel Trolley, which features automatic travel, automatic formwork adjustment, and automatic concrete pouring capabilities, significantly reducing manual support operations and enhancing tunnel lining efficiency and formwork precision. We provide a one-stop solution to meet the rapid construction requirements of subway tunnels, municipal tunnels, and utility tunnel projects.

We welcome you to visit the our factory to purchase customized subway tunnel formwork vehicles.

Core Technologies and Design Advantages

Precise tunnel cross-section shaping: Based on three-dimensional modeling of the tunnel cross-section, CNC bending and welding ensure a lining profile error of ≤0.3 mm, perfectly matching the tunnel design contour with uniform casting integrity.

High-rigidity overall frame: The main frame is constructed from thickened H-shaped steel welded together, featuring an enhanced support system that resists lateral concrete pressure, ensuring the casting platform remains free from deformation or displacement.

Fully hydraulic automated system: Equipped with hydraulic lifting, telescopic, and travel cylinders, the quality Subway Tunnel Trolley enables one-touch mold setting, demolding, and travel without manual formwork disassembly, increasing construction efficiency by over 60%.

Sealing and leakage prevention design: Weather-resistant sealing strips are installed at formwork joints, with end caps provided to prevent secondary lining slurry leakage or seepage, ensuring a dense and smooth concrete lining.

Safe Navigation System: A track-based automatic navigation system equipped with braking and limit switches ensures smooth and safe movement within tunnels, making it ideal for construction in confined tunnel spaces.

Application Scenarios

Our Subway Tunnel Trolley is suitable for secondary lining construction of subway circular tunnels, horseshoe-shaped tunnels, rectangular utility tunnel corridors, and municipal integrated utility corridors; specialized trolleys can be customized according to tunnel diameter, length, and cross-sectional configuration.

The kit includes a hydraulic system, travel tracks, vibration equipment, and a complete set of end sealing components, ready for immediate use after on-site assembly and debugging.

Experience Project Experience: 

A total of over 200 subway tunnel bogies have been delivered, covering metro and utility tunnel projects in major cities nationwide. These bogies are used for lining works in subway section tunnels and urban underground utility tunnels, achieving a 100% qualification rate for lining formation.

Customer Feedback: The tunnel construction unit reported that the mobile formwork system exhibits high automation and precise lining alignment, significantly reducing manual formwork installation and removal procedures. The secondary lining surface is smooth and flat, with no misalignment or slurry leakage, thereby markedly shortening the tunnel construction duration.

Construction guidance and support: Comprehensive technical training covering the entire process of gantry installation, commissioning, operation, and maintenance is provided, with on-site guidance from professional engineers to ensure safe and efficient tunnel construction.

Authority and Certification: 

Our Subway Tunnel Trolley has obtained ISO9001 and ISO14001 certifications. Upon leaving the factory, comprehensive tests have been conducted on structural load-bearing capacity, hydraulic systems, and travel accuracy, with third-party inspection reports and certificates of conformity provided.

Industry Collaboration: The company maintains long-term strategic partnerships with major domestic tunnel engineering bureaus and municipal groups. Its products are deployed in national key subway and utility tunnel projects, having demonstrated stable and reliable performance under complex underground conditions.

Production Capacity: Equipped with a large-scale steel structure processing workshop, the facility possesses comprehensive capabilities for the design, production, on-site installation, and commissioning of tunnel trolley systems. It is capable of undertaking customized delivery of tunnel trolleys with ultra-large cross-sections and extended lengths.

Reliability & Post-Sales Support: 

100% comprehensive testing and debugging before shipment; free repair or replacement of hydraulic and structural issues during the warranty period; full-process support throughout tunnel construction with on-site technical assistance.

Quality Commitment: High-strength steel is precision-welded in compliance with national standards; renowned brands are selected for the hydraulic system; third-party load and accuracy testing is conducted to ensure tunnel construction safety.

Case Study Example: Provides real-life footage of subway tunnel lining, visual rendering results, and project acceptance records, offering an intuitive demonstration of the mobile formwork construction effectiveness.

Product Features:

3. Fully hydraulic automated opaeration enables one-touch mold adjustment and movement, significantly improving construction efficiency. 

4. Sealed leakage-proof design maintains smooth lining surfaces, reducing subsequent repair requirements. 

5. Safe and stable operation in confined tunnel environments.  

Additional Features: 

1. Built-in vibration windows and inspection platforms facilitate concrete compaction and on-site monitoring. 

2. Compatible with simultaneous operations such as waterproof membrane installation and reinforcement binding. 

3. Modular formwork design enables easy intra-tunnel transportation, maintenance, and partial replacement. 

4. Moisture-resistant electrical and hydraulic systems adapted for damp and waterlogged tunnel conditions.  

Maintenance Recommendations

Clean formwork surfaces of residual concrete after each lining operation and inspect hydraulic cylinders for cement blockages.

Before operation, inspect the frame welds, hydraulic lines, and travel braking system; promptly address any abnormalities.

When stored for extended periods without use, clean the mud and debris from the cavity, remove rust from the frame, and apply rust-proof sealing to the hydraulic system.
