Second, each unit must strengthen rescue teams, equipped with rescue materials and equipment for bad weather, and take effective Anti-Slip measures for workers at high altitudes. Winds above level 4 should stop operations that are prone to dust lifting. Winds above level 6 are prohibited from high altitude operations. It is strictly forbidden to organize outdoor construction operations with rain, snow, and strong winds. If there is heavy snow, the water and snow on the construction site should be cleared in time. For example, if there is thick snow on the top of the tower and the top of the building facility that exceeds the design carrying capacity, personnel must be organized to evacuate.

Third, during the leisure time of winter construction, the tail of the tower crane should face the Northwest direction. The hook should be shrunk to the operating room. It can leave a small distance. If there is no obstacle around it, it can be allowed to swing freely with the wind. The hook can be controlled from the tower arm. Between 3 to 5 meters, Don't be too long.
Fourth, since winter is the peak period for tower lifting installation and tower lifting demolition, and it is also a dangerous period for high-altitude operations, it is necessary to file property rights for tower lifting equipment used or leased, and carry out operations within the scope of Tower lifting qualification permit. Taking into account climate factors such as large winter monsoon and increased rain and snow, special construction plans must be prepared before operation, and illegal operations are strictly prohibited.
