Abstract: Life yarn is used as a safety measure to prevent falling from high places in petrochemical engineering. Currently, standard formulation and manufacturing process monitoring on the use specifications, installation methods and safety performance parameters of life yarn in national and petrochemical industry need to be further improved, especially the lack of specific technical requirements for the use of life yarn, which brings safety hazards to field application. This paper established a geometric model based on the installation of the high-altitude frame life yarn and the overall layout drawing. On the basis of calculation and on-site installation, the load-bearing capacity and stability tests were carried out by simulating and calculating the working conditions. And the effectiveness of various life yarns with different sizes, specifications, setting-up methods and load-bearing capacity was obtained. This provides a basis for the reasonable setting-up and installation of life yarns at the construction site of petrochemical construction.
