Product Description
Product Overview
The Type 321 Bailey Bridge is a modular steel bridge system designed for rapid deployment in emergency situations and temporary infrastructure projects. Constructed from Q235 steel with galvanized Type 321 stainless steel components, this bridge offers exceptional durability and corrosion resistance.
Rapid Deployment Capabilities
Fast Assembly
Utilizing modular design principles, all components are factory-prefabricated and transported to site for quick assembly. This significantly reduces construction time, with documented cases showing a 12-meter span bridge being erected in just 1.5 hours.
Quick Dismantling
The modular system allows for equally efficient disassembly, with components being removed sequentially and transported away. This minimizes reliance on specialized equipment and personnel.
Proven Emergency Applications
During the 2008 Wenchuan earthquake, Type 321 Bailey Bridges played a critical role in disaster relief operations, ensuring transportation of supplies, evacuation of injured personnel, and movement of affected populations.
