Bailey Steel Bridge Erection and Lifting Operations: Safety First

Erection Methods: Common methods include the cantilever push-out method (requiring control of cantilever length) and the fishing method, among others. Selection should be based on site conditions.

Lifting Safety: Lifting operations must be uniformly directed, and no one is allowed to stand under the crane boom. Before operating equipment such as crawler cranes, inspect the steel cables, hooks, and braking systems. Personnel working on water must wear life jackets, and safety nets must be installed.

Process Monitoring: During the erection process, deformation and deflection at critical sections should be monitored in real time, especially under cantilever conditions. The overall deflection should be controlled within L/600 (where L is the span length).
