Bridge Steel Pipe/steel Pipe Bridge For Sale

The "321-Type" Bailey bridge is a versatile and rapidly deployable steel bridge system designed for various applications, including emergency response and temporary infrastructure needs. It was originally based on the British Compact-100 Bailey Bridge and adapted to meet the specific requirements and conditions in China.

Key Features of the 321-Type Bailey Bridge
- **Design and Construction**: The bridge is constructed using high-tensile strength steel, with lightweight composite panels connected by panel pins. This design allows for easy assembly, disassembly, and transportation.
- **Rapid Deployment**: The modular design enables quick setup and dismantling, making it ideal for emergency situations where rapid response is crucial.
- **Load Capacity**: The 321-Type Bailey bridge is suitable for smaller spans and lighter loads. It can be reinforced to handle heavier loads when necessary.
- **Customization**: The bridge can be customized to match the dimensions of existing bridges, particularly in international markets where compatibility with older structures is required.
- **Applications**: Widely used in emergency transportation, disaster relief, and temporary infrastructure projects.

Technical Specifications
- **Net Width**: 4.0 meters.
- **Maximum Free Span Length**: Up to 51 meters.
- **Panel Dimensions**: Standard panels are 3.048 meters by 1.45 meters (hole center distance).
- **Load Capacity**: Suitable for various load classes, including Truck-10, Truck-15, Truck-20, Tracklayer-50, and Trailer-80.

Environmental and Durability Considerations
The 321-Type Bailey bridge is designed to withstand harsh environmental conditions, with options for galvanization to enhance corrosion resistance. This ensures a longer lifespan with minimal maintenance.

Conclusion
The 321-Type Bailey bridge is a reliable and efficient solution for temporary and emergency bridge needs. Its modular design, ease of deployment, and adaptability make it a valuable asset in various engineering and humanitarian applications.
