Classification and structural characteristics of steel drag chain:

The steel drag chain shall be used on the cables, oil pipes, gas pipes, water pipes and air ducts of machine tools and machines for traction and protection. The use of steel drag chain originated in Germany, and later it was introduced and innovated in China. Now the steel drag chain has been widely used on the machine tool, which protects the cable and makes the machine tool look more beautiful as a whole. The steel drag chain can be divided into bridge type steel drag chain, fully enclosed steel drag chain and semi enclosed steel drag chain according to the use environment and requirements.

Structure of steel drag chain:

1. The steel drag chain looks like a tank chain and is composed of many unit links, which can rotate freely.

2. The steel drag chains of the same series have the same inner height, outer height and pitch, and the inner height and bending radius R of the drag chain can be selected differently.

3. The unit chain link is composed of left and right chain plates and upper and lower cover plates. Each section of the steel drag chain can be opened, which is easy to assemble and disassemble without threading. After the cover plate is opened, the cable, oil pipe, gas pipe, etc. can be put into the drag chain.

4. In addition, spacers can be provided to separate the space in the chain as required.
