100 Ton Tunnel Trestle Track Undercarriage | YIJIANG
100 Ton Tunnel Trestle Track Undercarriage
YIJIANG designed this heavy-duty track undercarriage system for a tunnel trestle with a total load capacity of 100 tons. The system consists of four single-side crawler undercarriage units, providing stable tracked mobility for large tunnel construction structures. Each single-side undercarriage measures 2605 × 500 × 1080 mm, while the four crawler units have a combined self-weight of approximately 8 tons and a travel speed of 1 km/h.

How Is the 100-Ton Tunnel Trestle Supported?
The undercarriage system uses four independent single-side crawler units to support and move the tunnel trestle.
Each crawler unit has a compact structural footprint of 2605 × 500 × 1080 mm. Four units are integrated into the complete trestle structure to distribute the machine load across multiple tracked contact points.
This configuration allows the tunnel trestle to maintain a large load-bearing capacity while remaining mobile during tunnel construction operations.
What Are the Main Features of This Tunnel Trestle Undercarriage?
100-Ton Total Load Capacity
The crawler system is designed to support a tunnel trestle with a total operating load of up to 100 tons. The four-unit configuration distributes the structural load across multiple crawler assemblies.
Four Independent Crawler Units
Instead of using one conventional crawler frame, this project uses four single-side track undercarriages. This configuration allows the crawler system to be integrated with the structural arrangement of the tunnel trestle.
Heavy-Duty Steel Tracks
Steel tracks provide a large ground-contact area and mechanical traction for heavy tunnel construction equipment. The tracked configuration is suitable for demanding construction environments where high load support is required.
Controlled Low-Speed Travel
With a travel speed of approximately 1 km/h, the undercarriage is configured for controlled movement rather than high-speed transportation. This is suitable for large structures that require stable positioning and slow travel during construction operations.
Compact Single-Unit Dimensions
Each crawler unit measures 2605 × 500 × 1080 mm, providing a relatively compact undercarriage package that can be integrated into the trestle structure according to the available installation space.
Why Does a Tunnel Trestle Use Four Track Undercarriages?
A large tunnel trestle has different structural and load-distribution requirements from conventional excavators or tracked machines.
The four-crawler configuration allows the undercarriage system to be arranged at multiple support points beneath the trestle. This provides a practical way to combine:
- High total load capacity
- Multiple load-bearing points
- Steel-track traction
- Low-speed movement
- Custom structural integration
YIJIANG develops the crawler units according to the overall structure, load distribution, mounting positions and travel requirements of the equipment.

How Was the Tunnel Trestle Undercarriage Configured?
The crawler system was developed around the structural requirements of the tunnel trestle rather than using a standard excavator undercarriage.
| Step | Configuration | Description |
|---|---|---|
| 1 | Total Load Requirement | Designed for a 100-ton total load capacity of the tunnel trestle system. |
| 2 | Crawler Arrangement | Four single-side crawler units were configured to support and move the complete trestle structure. |
| 3 | Individual Crawler Dimensions | Each crawler unit measures 2605 × 500 × 1080 mm, based on the available installation space. |
| 4 | Travel System | Hydraulic travel drive components were integrated for controlled movement at approximately 1 km/h. |
| 5 | Manufacturing & Assembly | The crawler assemblies were manufactured according to the project requirements and prepared for integration with the tunnel trestle. |
