Drag Chain

Silent Bridge-type Drag Chain

Suitable for reciprocating motion applications, the drag chain provides traction and protection for internally mounted cables, oil lines, air lines, water lines, etc. Each section of the drag chain can be opened for easy installation and maintenance. It operates with low noise, smooth wear, and is capable of high-speed motion. Drag chains are widely used in CNC machines, electronic equipment, stone processing machinery, glass machinery, door and window machinery, injection molding machines, robots, lifting and transportation equipment, automated warehouses, and other applications.

Selection of Drag Chain Installation Space

1. Determination of Internal Dimensions

The load, quantity, and diameter of cables, pneumatic tubes, and hydraulic tubes determine the internal dimensions and distribution of the drag chain. The load distribution within the drag chain must be reasonable and uniform, including the rational distribution of weight and space.

① The internal width and height of the drag chain are typically 1.5 times the maximum width and height of the pipeline arrangement.

② When there are multiple types of pipelines with large variations in quantity, diameter, and load, it is recommended to use separator sheets for isolation and arrangement.

③ The decision on whether to use a fully enclosed drag chain should be based on the use environment (e.g., dusty or chipping environments).

2. Calculation of Bending Radius

The selection of bending radius depends on the following two factors:

① Typically, the maximum diameter or thickness and the hardest pipeline determine the minimum bending radius of the drag chain.

② The available installation space determines the allowable bending radius, especially when the installation space is limited.

● Cables: The bending radius of domestically produced cables is 8~10 times their maximum outer diameter, while imported cables have a bending radius of approximately 6 times.

● Pneumatic/oil/water tubes: The bending radius is 10~12 times the maximum outer diameter of the pipeline.

● Actual installation height (HF): This serves as a practical reference value for the bending space of the drag chain.


Relationship between Drag Chain Length and Stroke

Stroke (S): Refers to the maximum distance traveled by the mobile end of the drag chain. The optimal solution is when the fixed end is positioned at the center of the stroke, minimizing the required length of the drag chain.

The formula applies to all applications where the fixed end is located at the center of the stroke, excluding rotational movements and long stroke applications.
