Engineering drag chain by material is divided into plastic engineering drag chain and steel engineering drag chain. According to the structure is divided into bridge engineering drag chain and full-closed engineering drag chain. Engineering plastic drag chains (engineering plastic drag chains) range in height from 10-80(mm) and in width from 10-350(mm) , depending on the size and number of cables you want to protect. The use intensity of the drag chain is mainly related to the content of nylon in the raw material. So engineering plastic drag chain is divided into ordinary engineering plastic drag chain and reinforced engineering plastic drag chain. Steel engineering drag chain is more used in offshore oil platforms, steel plants and other large heavy-duty machinery above, material has Q235,430,304 and other materials.

Steel drag chain models TL65, TL95, TL125, TL180. TL225, TL250, TLG75, TLG100, TLG125, TLG180, TLG225, TLG250. When the use of the environment is relatively bad when the general choice of fully enclosed engineering drag chain. Engineering drag chain, drag chain: beautiful appearance, light weight, length can be arbitrary self-adjustment. The use and characteristics of drag chain: suitable for use in the reciprocating movement of the occasion, to the built-in cable, tubing, trachea, water pipes and other traction and protection. Each section of the drag chain can be opened for easy installation and maintenance. Low Noise, wear-resistant, high-speed sports. Drag chain has been widely used in CNC machine tools, electronic equipment, stone machinery, glass machinery, doors and windows machinery, injection molding machine, manipulator, lifting equipment, automated warehouse.
