What safety measures do tower cranes take in foggy days in construction projects?

In case of severe weather, such as gale of magnitude 6 or above, heavy rain and fog, the tower crane should be stopped from working in the open air. After heavy wind and rain, try to lift the brakes first, and then operate after confirming that the brakes are sensitive and reliable.

The analysis is as follows:

According to the unified regulations of tower crane tower foundation standard, tower crane can work when the wind exceeds level 4, but if the tower crane is in non-working state, it should be parked with the wind to ensure that the balance arm of tower crane is not affected by the wind.

When the wind force exceeds 6, the tower crane should stop running to avoid the accident of balance arm.

Because the balance arm of the tower crane is long, the tower crane itself has carried too much building materials, so it is very dangerous to work against the wind. Once the huge tower crane breaks or even collapses, the consequences are unimaginable.

Extended data:

Before tower crane construction, it is necessary to obtain the form at the safety supervision station, handle the relevant information, submit it to the safety supervision station, and obtain the "permit" after approval, which is considered as formal construction. The process of treatment is as follows:

1. Filing formalities (i.e. entering the house): copies of the business license, product certificate, purchase and sale contract, sales invoice and supervision and inspection report of the property right unit are required. All stamped with the official seal of the property right unit. The safety supervision station of the local construction Committee shall handle it; After examination and approval, a "record certificate" and a "registration card (metal card)" will be obtained.

2. Go through the installation notification procedures: generally, when filing, you can get a set of forms and prepare the information as required. Only after the notification procedure is completed can the tower crane be installed.

3. Inspection: After the tower crane is installed, go through the relevant formalities at the safety supervision station, pay the inspection fee and ask for inspection. Waiting for the inspection report.

4. Go through the use registration formalities: bring the inspection report, also go to the safety supervision station to get the form, handle the relevant information, submit it to the safety supervision station, and get the "license" after approval, and the tower crane can be put into use.
