Ten major precautions when hoisting the space structure
2025-06-30
Complete the installation of the operator’s safety belt suspension device.
Organize the construction technology briefing and safety mobilization meeting. Make all personnel clear about the process and technical requirements for the installation of the space structure. Clarify the basic operating methods and relevant regulations for safe work.
Install the verticality correction process equipment for the grid components of the steel structure grid company before lifting. Such as: bundling of temporary fixing points of the cable wind rope. Determination and assembly of the fulcrum position of the correction support rod. Installation of temporary fixing devices for hoisting point positioning. Purpose: Limitation of the displacement of the steel structure plate edge edges and corners to prevent the cutting of the wire rope and the rope from falling off.
Complete the precise measurement and positioning work. ①. Use steel rulers, theodolites and levels that have passed the national metrology department’s inspection. ②. Measure the cross section of the steel ruler for inspection. Use a spring dynamometer of the corresponding specification. Look up the table and select the corresponding measurement size correction coefficient. And use measuring tools, instruments and correction coefficients correctly in measurement. ③. Use appropriate laying tools for laying and drawing lines.
Erection of scaffolding for construction personnel. Theoretical calculations should be guaranteed for personnel operating scaffolding. After the erection is completed, the safety technicians should organize the acceptance. It can only be used after passing the inspection. There should be a written acceptance record for the acceptance work.
Erection and installation of human fall protection safety net. After the erection is completed, the safety technicians should organize the acceptance. It can only be used after passing the inspection. There should be a written acceptance record for the acceptance work.
According to the construction organization design plan: the steel structure project organizes and numbers different steel structure components and structural characteristics according to the hoisting sequence. Stacking work is carried out according to the planned design location map.
Complete the arrangement of the operator to the simple road on the construction surface.
Check and inspect the crane rigging and safety acceptance work. Make written records and handle the signature procedures of relevant personnel.
Move the steel structure components before lifting horizontally to the lifting position.
