Tower crane construction safety first, efficiency second.
In order to prevent the whole tower crane from leaning backward or the boom from leaning backward, small-scale, light-load and windward operation should be avoided, the wind force on the suspended tower crane should be guaranteed to blow from behind, the windproof and skid-resistant safety device should be used and maintained correctly, and the wind speed and wind level alarm should be installed in the upper part of the tower crane without windshield. After the tower crane stops working, it is necessary to ensure that the wind-proof and skid-resistant safety device enters the working state, and there can be no chance mentality. At the same time, we should pay attention to the weather changes and make full preparations for the predicted gale. When the wind reaches a certain level, we should stop working. The wind power that stops working is classified as greater than 6 in inland areas and 7 in coastal areas.
In the non-working state, the brake must be loosened to ensure that the crane boom can rotate in the direction of wind.
