Safety Control For Steel Bridge Erection

Safety control during the erection process is critical, with key measures including:

Component Inspection: Strictly inspect components such as Bailey panels prior to installation; damaged or deformed components must not be used to prevent uneven stress distribution.

Precise Layout: Accurately mark positions on the pier cap beams to ensure correct placement of Bailey beams, with longitudinal deviation not exceeding 2 cm and lateral deviation within ±2 cm.

Lifting Safety: Conduct safety calculations for lifting equipment, rigging, and bridge structure before hoisting to ensure stability throughout the lifting process.

Process Monitoring: During the pulling and launching operation, maintain unified command, continuously monitor roller conditions and bridge movement, and immediately halt operations upon detecting any abnormalities.
