Solving Common Cable Snags in Plastic Drag Chains

Plastic drag chains are used in a variety of industries to protect and organize cables and hoses that need to move with a machine. However, cable snags can occur, causing downtime and costly repairs. In this article, we will look at some common causes of cable snags and how they can be prevented.

Plastic Drag Chain in Action

What is a Plastic Drag Chain?

A plastic drag chain, also known as a cable carrier, is a piece of equipment used to guide and protect cables and hoses on moving machinery. The chains are made of interlocking plastic links that can flex and bend as the machine moves. They are commonly used in industries such as automation, robotics, and material handling.

Common Causes of Cable Snags

1. Insufficient Tension

When a drag chain is not under enough tension, the links can separate and create gaps that cables can get caught in. This is especially common in long cable runs, where the weight of the cable can cause it to sag.

2. Twisting and Kinking

When cables twist or kink inside a drag chain, they can become tangled and cause snags. This is often caused by improper cable dressing or excessive cable length inside the chain.

3. Chain Wear

Over time, drag chains can become worn and damaged, creating rough or uneven surfaces that can catch on cables. This is especially true in high-speed applications or harsh environments.

Preventing Cable Snags

1. Proper Tensioning

Proper tensioning is critical for preventing cable snags. A drag chain should be under enough tension to keep the links closed, but not so much that the chain is difficult to move. Tension should be checked regularly and adjusted as needed.

2. Cable Dressing

Cables should be dressed properly inside the drag chain to prevent twisting and kinking. Any excess cable length should be removed, and cable ties should be used to keep the cables in place.

3. Regular Maintenance

Regular maintenance is essential for keeping drag chains in good working order. Chains should be inspected for wear and damage, and replaced as needed. Lubrication should be applied regularly to keep the chain moving smoothly.
