L68B2 Mast Section Attention to the use of Tower lifting equipment in low temperature season
Due to the cold environment and wind power in winter, there are some precautions for the use of Tower lifting equipment:
First, before the construction of the tower crane, the site construction and supervision party paid great attention to the local wind power. When the wind speed is greater than 15 m/s, the tower crane team should stop the construction and pay attention to rest.
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 windy weather. If there is heavy snow, it is necessary to remove water and snow from the construction site in a timely manner. 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, and the hook should be shrunk to the operating room. A small distance can be left. If there are no obstacles around, it can be allowed to swing freely with the wind. The hook distance can be controlled between 3 and 5 meters, remember that it is too long.
