Best Practices for Inspecting Plastic Drag Chains for Hidden Damage

Plastic Drag Chain in Use

Plastic drag chains are frequently used in industrial settings, where they are subjected to a wide variety of stresses and strains. Over time, these stresses can cause hidden damage to the chain that can ultimately lead to failure if not addressed. In order to prevent unexpected downtime and costly repairs, it’s important to regularly inspect your plastic drag chains for signs of damage. In this article, we will outline best practices for inspecting plastic drag chains for hidden damage, and provide tips for addressing any issues that you may find.

Visual Inspection

The first step in inspecting your plastic drag chain is to conduct a visual inspection. This should be done while the chain is in operation, if possible, as it will allow you to identify any issues that may not be visible while the chain is at rest. Look for any signs of wear, such as cracks or breaks in the chain links, or any obvious deformities. Additionally, look for any signs of debris or other materials that may have become lodged in the chain links, as these can cause additional wear and tear on the chain.

Physical Inspection

Once you have completed your visual inspection, it’s time to conduct a physical inspection of the chain. This will involve taking the chain apart and examining each link individually for signs of damage. Look for any cracks, chips, or other deformities, and take note of any sections of the chain that appear to be excessively worn. Additionally, inspect the pins and bushings of the chain, as these are critical components that can cause issues if they become worn or damaged.


After completing your visual and physical inspection, it’s important to test the chain to ensure that it is functioning properly. This can be done by running the chain under a load and monitoring its performance. Look for any signs of the chain slipping or jumping, as these can be indicators of issues that need to be addressed.

Preventative Maintenance

Finally, it’s important to develop a preventative maintenance plan for your plastic drag chains. This should include regular inspections and testing, as well as the replacement of any worn or damaged components. By taking a proactive approach to maintenance, you can avoid unexpected downtime and extend the lifespan of your plastic drag chains.


Regular inspection of your plastic drag chains is essential for ensuring safe, efficient operation in industrial settings. By following the best practices outlined in this article, you can identify hidden damage and address any issues before they lead to costly downtime and repairs.
