It should be hung with safety inspection qualification signs, safety warning signs and other safety signs, so as not to affect the wind resistance.
According to Sina: The safety signs that should be hung on the tower crane include security inspection qualification signs, safety warning signs, safe operating procedures signs, fixed position and minimum number signs, and tower crane ten no hanging signs. Note that these signs are approved by the "Construction Tower Cranes" "Safety Technical Regulations for Installation, Use and Disassembly" is mandatory. These signs generally include the maximum load-bearing capacity of the tower crane, safe operating procedures, grounding protection measures, etc.
It is very important to hang safety signs on tower cranes because they can remind staff and other personnel to pay attention to safety matters. Safety signs hung on tower cranes usually do not affect wind resistance because these signs are generally smaller and weigh less. However, if large billboards or other items are hung on the tower crane, it will affect the wind resistance of the tower crane. This will not only affect the stability of the tower crane, but also pose a threat to surrounding buildings and personnel.
2、I would like to ask how the tower crane responds in windy weather
1. All components of the tower crane should be compre hensively inspected regularly and repaired and maintained in a timely manner.
2. Pay close attention to the weather and wind trends, and check whether the tower body, wall-attached poles, mechanisms, billboards, electrical boxes, lamps, etc. are firmly connected.
3. The hook should be raised to the highest point, the boom should be able to rotate with the wind, and there should be no obstacles within the rotation range.
4. When the wind is too strong, the independent-height tower crane should be lowered by at least 1/3 of its height, or an attached wall should be installed on the top of the tower, and the height should be appropriately lowered until it does not touch the top of the building.
5. If necessary, the steel pipes, scaffolding and other facilities on the roof should be removed to lower the tower body as much as possible. When the tower crane is independently fixed at a height that meets the cable wind rope solution, cable wind rope protection can be used.
6. According to the wind direction, when installing the tower crane, try to install it on the leeward side of the building that can block the wind.
3、The large signs installed on the tower crane's boom and balance arm should act as sails
Yes. For billboards on the tower crane's balance arm, the tower crane should be in an automatic downwind state when there is wind. Therefore, after hanging the billboard, it should not affect the wind rotation of the tower crane's front and rear arms, otherwise the tower crane will lose its automatic downwind protection function. Therefore, the large signs set on the tower crane's boom and balance arm should act as sails.
4、How much does it cost to install billboards on a tower crane?
The prices of different tower cranes vary depending on the new and old ones, the brands, and the regions. There is a price for the tower crane's entry and exit, installation, wall attachment, installation, dismantling, etc.
Give me a rough reference, here in Fujian (there are differences in different regions). The installation cost is about 5000~8000. Rental costs vary greatly. 100 tons of rice, the Senbi brand is better, about 20,000 a month
