- There are no people staying in the operating range of the crane, and try to avoid people passing through.
- When the wind power of outdoor cranes exceeds level 6, work should be stopped immediately. Cut off the power and pull the wind rope. Usually the same thing should be done after get off work.
- It is strictly forbidden to pile up debris on the crane platform. In order to prevent the operation from falling and hurting people, the frequently used tools should be placed in the special tool box in the operating room.
