Description

[0002] When installing outdoor high-altitude steel structure foundation components, the staff will use a car crane to lift the steel structure components to the installation height, and the staff at the top of the components will install them uniformly; for small components, the installation is very simple, but for larger components, such as purlins, the lifting and installation are somewhat difficult. The traditional lifting method is: first use a rope to string the purlins, and then use a car crane to lift the purlins to the top of the steel structure. In this process, since the purlins are strung through the ropes, the purlins will shake during the lifting process. If you are not careful, it will cause safety hazards to the staff; when the purlins are hoisted to the top of the steel structure, the staff are required to use manual handling to lift the purlins to the installation position. This construction method is time-consuming and labor-intensive, and inefficient. The porters on both sides need to keep pace to ensure its safety. Summary of the invention
