In modern tunnel construction, tunnel trestle bridges have become indispensable “aerial corridors” to enable parallel operations of excavation, muck removal, and invert and secondary lining. However, how can we ensure the stable support and precise movement of steel structure trestle bridges, which often weigh tens or even hundreds of tons, within narrow, damp, and geologically complex tunnels?
Customized heavy-duty steel tracked undercarriage provide the answer. Based on the actual construction needs of customers, this “hardcore” undercarriage is playing an irreplaceable role.
1. Ultimate Load-Bearing Capacity, Ensuring Absolutely Flawless Construction Safety
Tunnel trestle bridges are not only enormous in weight, but also need to withstand frequent passage of heavy vehicles such as muck trucks and concrete mixer trucks during operation. This places extremely high demands on the load-bearing capacity of the support system.
• Customer Value: The customized steel tracked undercarriage, made of high-strength alloy materials, can easily handle dynamic and static loads of 30-60 tons. It’s not just the “feet” of the trestle, but also the “stabilizing force” of the entire construction platform, completely eliminating safety hazards caused by unstable support.
2. Precise Movement, Significantly Improved Efficiency
Moving the trestle in the confined space of a tunnel is not only time-consuming and labor-intensive, but also carries a high risk of collision.
• Customer Value: The customized hydraulic drive system, combined with steel tracks, provides powerful traction and on-the-spot turning capability. Even within the limited space of the tunnel, the trestle can be moved smoothly and precisely. This means a shorter construction cycle and lower labor costs—faster equipment means faster project completion.
3. Conquering Extreme Environments, Reducing Equipment Maintenance Costs
The environment at the bottom of tunnels is complex, often containing water, rock debris, and chemical slurries, making ordinary walking systems highly susceptible to damage.
• Customer Value: The steel tracked undercarriage has inherent “armor” properties. The induction-hardened tracks and wear-resistant track plates can withstand the abrasion of sharp rocks and the erosion of humid environments. For customers, this means extremely low maintenance frequency and longer service life, avoiding project downtime due to undercarriage failure.
4. Highly Adaptable, Tailor-Made for Different Working Conditions
Every tunnel has different cross-sectional dimensions, slopes, and geological conditions, making standardized undercarriage often insufficient for specific needs.
• Customer Value: From track gauge and wheelbase to ground clearance and even the torque distribution of the travel motor, everything can be deeply customized according to the trestle’s structure and construction step distance. This “tailor-made” service ensures a perfect integration of the undercarriage and trestle structure, maximizing the overall efficiency of the equipment.
Choosing a undercarriage Means Choosing Construction Stability
