Product Description

Type 450 Bailey Bridge for Emergency Response

Our prefabricated structural steel emergency bridge delivers rapid deployment and exceptional load capacity for disaster relief operations and temporary infrastructure solutions.

Key Advantages for Earthquake Rescue Operations

Rapid Construction: Modular design enables factory prefabrication and on-site assembly within hours
High Load Capacity: Supports crawler loads up to 500 kN and tire loads up to 300 kN (130 kN axle pressure)
Terrain Adaptability: Deploys across rivers, canyons, and various obstacles with flexible configuration options
Temporary Bridge Solution: Ensures traffic continuity when permanent bridges are damaged or destroyed
International Certification: Compliant with Chinese, American, and European standards for global deployment
Seismic Performance: Engineered to withstand post-earthquake terrain conditions with enhanced stability
Reusable Components: Modular design allows multiple deployments, reducing long-term project costs
