Compact 200
BAILEY
The CB-200 Bailey Bridge, also known as the Compact 200, is a modular steel bridge system designed for temporary access and structural support in heavy construction environments. This system provides reliable solutions for hydropower projects, where challenging terrain and heavy equipment movement require robust, quickly deployable infrastructure.
The CB-200 system features a truss design that distributes loads efficiently across multiple components. Each panel is engineered to work in conjunction with others, allowing for flexible configuration based on span requirements and load specifications. The modular nature of the system enables adaptation to various site conditions without extensive on-site modification.
All components are manufactured from Q355B to Q460C grade steel, conforming to both ASTM and GB standards. Production processes maintain a tolerance of ±1% across all dimensions. The manufacturing facility has a production capacity of 2500 tons per month, enabling consistent supply for large-scale projects.
Hydropower projects often require temporary infrastructure to facilitate construction activities in remote or difficult-to-access locations. The CB-200 Bailey Bridge system addresses multiple critical needs in these environments.
The system provides temporary crossing solutions over rivers, ravines, and uneven terrain, enabling the movement of construction vehicles, equipment, and materials to project sites. These bridges can be installed quickly to establish access routes early in the project timeline.
Beyond bridge applications, CB-200 components can be configured into shoring towers and support structures for heavy construction operations. This versatility allows the same components to serve multiple purposes throughout different phases of a hydropower project.

In collaboration with China Railway 24th Bureau Group, the system was used for a major bridge construction project in Hangzhou, Zhejiang Province. The project required the installation of a 1800-ton steel box girder segment using the float-over method, which demands precise control and exceptional structural strength from temporary works.
Type 321 Bailey components were engineered into two full-framing support towers mounted on barges. Each tower was constructed with 11 layers of Bailey panels, reaching a height of 16.5 meters on a 27m × 21m base. These structures formed the core of the float-over system, working in conjunction with a sophisticated barge ballasting system.
The Bailey towers safely supported the entire 1800-ton weight of the steel girder during lifting, lowering, and placement operations. The modular design allowed for rapid assembly and disassembly, contributing to efficient project execution. All components were fully reusable for subsequent projects.
Modular steel bridge systems offer distinct advantages for industrial construction projects compared to traditional temporary infrastructure solutions.
The prefabricated components can be assembled using standard construction equipment without specialized tools. This reduces on-site labor requirements and shortens project timelines significantly.
All components are designed for multiple deployments across different projects. This reusability lowers the overall cost of temporary works and reduces material waste.
The system can be configured for various applications beyond bridge construction, including shoring towers, temporary platforms, and support structures. This versatility maximizes the value of the investment for industrial buyers.
The maximum span depends on the configuration and load requirements. Single-lane configurations can achieve spans up to approximately 60 meters, while multi-lane configurations have different span capabilities based on load ratings.
The system can be configured to support various load capacities, ranging from light vehicle traffic to heavy construction equipment and specialized loads up to 1800 tons when used in shoring tower configurations.
Yes, CB-200 components are designed to be compatible with standard Type 321 Bailey bridge components, allowing for mixed configurations and component interchangeability.
Production lead times vary based on order quantity and current production schedules. Standard orders typically ship within 30-45 days from order confirmation.
Yes, the modular design allows for customization to meet specific project needs, including different span lengths, load capacities, and configuration requirements.
