- When installing and erecting, pay attention to wind speed changes. The wind speed must conform to the design regulations, and generally should not exceed 13m/s.
- The connection between the crane parts is correct and reliable.
- During installation and erection, attention should be paid to observation and monitoring, unified command and reliable contact.
- Lifting equipment and hoisting rigging should be strictly checked before use.

- Carefully observe the requirements of the lifting equipment capacity, the quality of the lifting components, the position of the center of gravity, the overall dimensions, and the height of the lifting point in the gantry crane manual.
- Before lifting materials, after carefully checking the lifting equipment and hoisting rigging, a trial hoist should be carried out to confirm that it is safe and reliable.
