Galvanized Steel Truss Pedestrian Bridge Prefab Steel Bridges ISO9001

Galvanized Steel Structure Pedestrian Bridge/prefab Steel Structure Pedestrian Bridge

The 450-type Bailey bridge developed by Jiangsu Zhonghai Bridge Equipment Co., Ltd. has significant engineering application advantages and can meet a variety of complex engineering needs:

1. **Long-span bridge construction**
The 450-type Bailey bridge can achieve a large-span single-span structure with a maximum span of up to 91 meters. This large-span capability makes it suitable for crossing natural obstacles such as wide rivers, canyons or deep valleys, and for use as a temporary or permanent bridge in large infrastructure projects.

2. **High-load transportation**
This type of Bailey bridge is designed to carry heavy loads and can meet the needs of various vehicles with a crawler load of 500 kN and a tire load of 300 kN (axle pressure of 130 kN). This makes it have important application value in projects that require the transportation of heavy equipment and materials.

3. **Rapid deployment and temporary use**
The modular design of the 450-type Bailey bridge enables it to be quickly assembled and disassembled, making it suitable for emergency rescue and temporary bridge construction. In natural disasters or emergencies, it can be quickly built to provide transportation guarantees for rescue teams. In addition, it can also be used as a temporary bridge to replace the construction of a permanent bridge to ensure the continuity of traffic.

4. **Strong adaptability**
This type of Bailey bridge can be composed of various types and uses of bridges according to the different spans actually needed, including one-way, two-way, and bridges with external or internal sidewalks. Its strong adaptability enables it to meet the requirements of different terrains and environments, and is suitable for a variety of scenarios such as urban traffic, mountain bridges, and river bridges.

5. **Reuse and economy**
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.

6. **International standard certification**
The new Bailey bridge has 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.

In summary, the Type 450 Bailey Bridge can be widely used in a variety of engineering scenarios with its advantages such as large span, high load, rapid deployment, strong adaptability, economy and international standard certification, providing reliable support for large-scale infrastructure construction, emergency rescue and temporary transportation solutions.
