The fabricated support and hanger is a new type of fabricated support and hanger, which is developed to solve a series of shortcomings such as high-end products of cylindrical spiral material, heavy weight, unreasonable structure and inconvenient on-site assembly adjustment. For the prefabricated support and hanger, it also has its own advantages and disadvantages in design. The summary is as follows: the advantages of the fabricated support and hanger are: it integrates the lock system, limit system and protection system in one, which is convenient for on-site installation, debugging and maintenance. Because the elastic components are assembled, the application scope of supports and hangers is expanded, the volume, weight and cost are reduced. of course. Everything is not perfect, and the fabricated supports and hangers also have shortcomings. Its main disadvantage is that it needs regular maintenance of the fabricated working environment to ensure the use efficiency of the fabricated supports and hangers.
