The role of drag chain is mainly used to protect and guide cables, trachea, hydraulic pipe and other components, to ensure that these components can work stably and safely in the process of equipment movement; the design of drag chain enables it to stretch and bend, and keep the internal cable and other equipment relatively stable, so as to avoid damage caused by external environmental factors (such as friction, impact, etc.);

Type of drag chain 1. According to the material of steel drag chain, plastic drag chain, steel and aluminum drag chain, nylon drag chain; steel drag chain because of its high strength and wear resistance, often used in machine tools and other occasions; plastic drag chain because of its light, corrosion resistance and other characteristics, widely used in electronic equipment and other fields;

• Classification the opening diameter or outer diameter of the inner diameter according to the opening method of the drag chain: this opening method allows users to easily install, remove or repair the internal cables, trachea and other parts through the opening of the inner diameter or outer diameter, which makes more convenient operation and improves work efficiency;

Inner and outer diameter opening: the horizontal bar of the drag chain can be opened either in either the inner diameter direction or in the outer diameter direction, providing users with greater flexibility, especially when dealing with different sizes and types of pipelines;

Open on both sides: this type of drag chain has openings on both sides, which is convenient for users to install and remove pipelines from either side, improving the convenience of operation; there is an open horizontal bar, which is mainly used for those occasions that do not need frequent pipeline maintenance or replacement, with higher structural stability and sealing;

Note: try not to use non-open, except in special circumstances, for maintenance or assembly is not convenient.
