Regardless of the tower crane, you should understand that it is mainly composed of three parts: the rise and change of the rotation. If the entire machine does not work, check the total part.

If the main hook does not work, check the ascending part; If the amplitude does not work, check the car part; If it doesn't work, check the swivel part.

winds can a tower stand up to
The windy weather is a common weather. When many construction sites encounter windy weather, they still require the tower crane driver to continue construction.

This not only makes the operators frightened, but also may cause serious tower hanging accidents.
The construction site is also required to take risks due to the tight schedule. When the wind blows, when the tower crane driver of the tower crane operates the tower crane, he will feel that the tower crane is shaking and he is worried about accidents.

 The tower suspension operated by the tower crane driver is more than 20 meters high, and the balance arm forearm is only 46 meters.

Because the tower suspension building materials are often used for several tons, the tower suspension with poor balance is very powerful. A tower crane driver said: "I am very worried inside and I am always afraid that the tower will fall. Due to manpower constraints, the site sometimes allows some workers who do not have a tower crane operation license to operate the tower crane.

 Due to the lack of experience of these people, coupled with strong winds, accidents are more likely to occur.
Many site towers are operating in the "windward" operation. Due to the lack of protection measures on many sites, the public is also afraid of these "behemoths." "The wind is still working. What if there is an accident?

 The relevant person of the construction safety production supervision station stated that according to the unified regulations of the tower tower base standard, when the wind power exceeds the fourth grade, the tower crane can work, but if the tower crane is in a non-working state, it should be parked downwind to ensure that the tower crane balance arm is not affected by the wind.

When the wind exceeds the sixth grade, the use of Tower cranes should be stopped to avoid accidents in the balance arm.

 At the same time, relevant sources pointed out that due to the long balance arm of the tower crane, the tower crane itself has suffered heavy construction materials, and forced headwind work is very dangerous. Once such a huge tower crane breaks or even collapses, the consequences are unimaginable
