Can the 450 Bailey Bridge pass through rivers?

The 450 Bailey Bridge is fully capable of passing through rivers, and its design and structure give it significant advantages in river crossing applications.

1. **Large span capability**
The 450 Bailey Bridge has a maximum single span of up to 91 meters, which can easily cross wide rivers. This large span capability makes it suitable for various complex terrains and environmental conditions, ensuring that the bridge can cover the width of the river and provide continuity for traffic.

2. **Quick construction**
The Bailey Bridge adopts a modular design, and each component can be prefabricated in the factory and then transported to the construction site for rapid assembly. This design greatly shortens the construction period, allowing the Bailey Bridge to be completed in a short time, ensuring the rapid passage of rescue materials and personnel.

3. **High load-bearing capacity**
The 450 Bailey Bridge is designed to carry heavy loads and can meet the needs of various vehicles with a tracked load of 500 kN and a tire load of 300 kN (axle pressure of 130 kN). This high load-bearing capacity makes it of great application value in projects that require the transportation of heavy equipment and materials.

4. **Adaptability**
The Bailey Bridge can adapt to different terrain and environmental requirements, and can provide reliable solutions whether it is crossing rivers, canyons or other obstacles. The flexibility of its design allows it to be adjusted according to actual needs to meet different engineering needs.

5. **Temporary Bridge Solution**
In the event that the existing bridge on the river is destroyed or the road is interrupted, the 450-type Bailey Bridge can be used as a temporary bridge. It can be quickly erected to ensure the continuity of traffic until the permanent bridge is repaired or rebuilt.

6. **International Standard Certification**
The 450-type Bailey Bridge has been simultaneously applied for three sets of standard certifications in China, the United States and Europe, with the goal of further expanding the global market. This shows that its design and manufacturing meet high international standards and can meet the engineering needs of different countries and regions.

7. **Seismic Performance**
The Bailey Bridge is designed with good seismic performance and can adapt to the complex terrain and environment after an earthquake. This performance makes it perform well in rescue work after natural disasters such as earthquakes, providing strong support for rescue work.

8. **Reuse**
The components of the 450 Bailey Bridge can be reused, reducing long-term engineering costs. This economy gives it a significant advantage in projects that require temporary or semi-permanent bridge solutions.

In summary, the 450 Bailey Bridge performs well in river crossing applications with its advantages such as long span capability, rapid construction, high load-bearing capacity, strong adaptability, temporary bridge solution, international standard certification, seismic performance and economy, and can provide a reliable solution for river traffic.
