When the tower crane is working, the wind speed is lower than several levels.

The wind speed of tower crane at work should be lower than level 6.

Gale weather is a common weather. Many construction sites still require tower crane drivers to continue construction when encountering windy weather, which not only scares operators, but also may cause serious tower crane accidents.

When the wind blows, the tower crane driver who drives the tower crane will feel that the tower crane is shaking badly when operating, and he is worried about accidents. The tower crane operated by the tower crane driver is more than 20 meters high, and the forearm of the balance arm alone is 46 meters. Because there are often several tons of building materials for tower cranes, tower cranes with poor balance themselves sway badly.

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. Platforms, walkways, skirting boards and railings, ladders, handrails and guardrails are the passages and protective facilities for tower crane operators to walk on the tower crane. Their installation quality is related to the personal safety of operators, so they should be installed correctly and intact.

Balance weight is a balance component to maintain the stability of tower crane and realize the lifting performance of tower crane. It should be noted that different lengths of boom correspond to different counterweights during the test.
