[0002] Cable trays are structural facilities used to support and protect cables. They are usually composed of trays, straight sections of ladders, bends, accessories, and supports. They have a supporting function and can bear the weight of a large amount of cables to prevent the cables from being damaged by their own weight or external forces; they also have a protective function to prevent the cables from being affected by external factors such as mechanical damage, chemical corrosion, and electromagnetic interference; at the same time, they are easy to manage and maintain, making cable laying more standardized and orderly, convenient for inspection, repair and replacement, and easy to identify different types of cables, thereby improving work efficiency.

[0003] When cable trays are produced, accessories are placed on the workbench of the production line for welding.
