What safety tags should be hung on tower cranes?

The safety signs that should be hung on the tower crane are:

1. Security inspection qualification sign

2. Safety warning sign

3. Safety Operating procedures sign

4. Fixed position and fixed number of personnel sign

5. Tower crane no-lift sign

High-rise buildings have developed rapidly, and the use of vertical transport mechanical tower cranes during construction has increased rapidly. The number of accidents has increased sharply, and major safety accidents involving tower crane overturning have also occurred frequently. Prevention is the key.

1. When a slip occurs during work, the driver should remain calm and notify the signalman to let the ground personnel leave in time. According to the operating procedures, heavy objects are placed in the uninhabited area of ??the site through hooks, booms, traveling vehicles, etc.
