Custom Steel Track Undercarriage System for a 100-Ton Tunnel Trestle Bridge
YIJIANG supplied four custom steel track undercarriage units for a tunnel trestle bridge, forming a crawler mobility system with a combined load capacity of approximately 100 tons.
Project Introduction
YIJIANG supplied four custom steel track undercarriage units for a tunnel trestle bridge, forming one crawler mobility system with a combined load capacity of approximately 100 tons. Each crawler unit is designed for approximately 25 tons of load and measures 2605 × 500 × 1080 mm.
The steel track undercarriages use hydraulic drive and were customized to match the trestle's load requirements, mounting structure, dimensions and tunnel operating conditions. The four crawler units work together to support and move the heavy trestle structure inside the tunnel.

How Does the Four-Unit Crawler System Move the Trestle?
The tunnel trestle is supported and moved by four custom steel track undercarriage units, which work together as one crawler mobility system. Each undercarriage is installed at a designated support point beneath the trestle structure, distributing the overall load across four crawler units.
Four Crawler Units Support the Trestle
The four undercarriages provide multiple support points beneath the trestle. With approximately 25 tons of load capacity per unit, the system provides a combined capacity of approximately 100 tons for the complete trestle structure.
Hydraulic Drive Provides Traction
The crawler undercarriage system uses hydraulic drive to generate the traction required to move the heavy trestle along the tunnel floor.
The Undercarriages Work as One Mobility System
During movement, the four crawler units work together to move the trestle as a complete structure rather than operating as independent machines. This multi-point crawler configuration helps maintain load distribution and stable contact with the tunnel floor while the trestle is being moved.
Designed for Controlled Movement in Confined Tunnels
The crawler system is designed around the dimensions and operating conditions of the tunnel trestle. The compact custom configuration allows the four units to provide heavy-load support and controlled crawler movement within the available tunnel space.
Why Was a Custom Steel Track Undercarriage Required?
The tunnel trestle required a dedicated crawler system to support its heavy structure and provide stable movement inside a confined construction environment. A standard undercarriage could not directly meet the project's load, dimensional and mounting requirements, so YIJIANG developed a custom steel track solution.
Heavy Trestle Load
The crawler system needed to support a large and heavy tunnel trestle structure. Four steel track undercarriage units were configured as one complete mobility system, with a combined load capacity of approximately 100 tons.
Limited Tunnel Space
Tunnel construction provides limited operating space compared with open-site applications. The undercarriage dimensions and track width therefore had to be designed to fit the available space while maintaining sufficient stability and ground contact.
Uneven and Demanding Ground Conditions
Tunnel floors can include uneven surfaces, construction debris, rocks and wet areas. The steel track configuration provides a durable contact surface and the traction required for heavy-duty movement in these demanding conditions.
Stable Movement Under Heavy Load
The trestle needed controlled and stable movement rather than simply supporting the structure. The hydraulic drive system provides the required traction and allows the four crawler units to move the trestle as an integrated system.
Non-Standard Mounting Requirements
The crawler units therefore had to match the specific structure and connection points of the tunnel trestle.
How Was the Undercarriage Customized for Tunnel Construction?
YIJIANG customized the steel track undercarriages according to the tunnel trestle's load, dimensions, mounting structure and movement requirements.

Project Result
The four custom steel track undercarriages provided the tunnel trestle with a dedicated heavy-duty crawler mobility system. With approximately 25 tons of load capacity per unit, the four-unit configuration provides approximately 100 tons of combined load capacity.
The hydraulic-driven steel track system provides the required traction and support for moving the trestle within the tunnel. The customized dimensions and mounting structure allow the crawler units to integrate with the specific trestle design.
FAQ
Q: What type of undercarriage was used for the tunnel trestle?
A:The tunnel trestle uses a custom heavy-duty steel track undercarriage system with hydraulic drive. The system was designed specifically for the trestle's load, dimensions, mounting requirements and tunnel operating conditions.
Q: How many crawler undercarriages were used for the tunnel trestle?
A: The complete system uses four custom steel track undercarriage units. The four units work together to support and move the tunnel trestle.
Q: What is the load capacity of the tunnel trestle undercarriage system?
A:The four-unit system has a combined load capacity of approximately 100 tons, with approximately 25 tons of load capacity per crawler undercarriage.
Q:Can YIJIANG customize steel track undercarriages for other tunnel equipment?
A: Yes. YIJIANG can customize steel track undercarriages for tunnel and other heavy construction equipment according to the required load capacity, overall dimensions, track width, mounting interface, hydraulic drive system and operating conditions. Custom designs can be developed for non-standard machinery and specific project requirements.
