Step-by-Step Leaf Chain Inspection Guide


Leaf chains are an essential component in the functioning of many industrial applications, including elevators, forklifts and construction machinery. They are designed to handle heavy loads and last for long periods, even under harsh conditions. However, like any other mechanical component, they require regular inspection and maintenance to ensure their longevity and reliability. In this guide, we will take you through a step-by-step process for inspecting leaf chains and identifying potential issues before they become major problems.

Leaf Chain Application

Step 1: Visual Inspection

The first step in inspection is to conduct a visual inspection of the chain. Look for signs of wear, such as cracks, excessive elongation, or corrosion. Check for any missing components, such as pins, bushings, or rollers. Ensure that the chain is properly lubricated and that there are no kinks or twists in the chain. Any issues identified during this inspection should be noted and addressed before proceeding to the next step.

Step 2: Measurement

The next step is to measure the length of the chain. A leaf chain should be replaced if it has elongated by more than 3% of its original length. Measure the pitch of the chain and compare it with the manufacturer's specifications. Check the thickness of the chain and ensure that it is within tolerance. Record any measurements that fall outside the expected range.

Step 3: Pin Inspection

Check the pins for signs of wear or damage. Any visible signs of wear or corrosion should trigger a chain replacement. Check that the pins are properly seated and that there is no evidence of pin rotation. A loose pin can cause premature chain failure and should be rectified immediately.

Step 4: Bushing Inspection

Bushings are a critical component of leaf chains and must be inspected carefully. Check for wear or damage to the bushings. Ensure that the bushings are properly lubricated and that they are properly seated in the link plates. Any issues with the bushings should be addressed immediately.

Step 5: Roller Inspection

Rollers are designed to carry the load between the chain and the sprocket. Check for wear or damage to the rollers. Ensure that the rollers are properly lubricated and that they are not worn beyond their tolerance. Any issues with the rollers should be addressed immediately.

Step 6: Assembly Inspection

Check the assembly of the chain and ensure that the correct components have been used. Ensure that the cotter pins are properly installed and that they are not damaged or missing. Ensure that all link plates are properly aligned and that the chain is not twisted. Any issues with the assembly should be addressed immediately.


Leaf chains are essential components in many industrial applications and must be inspected regularly to ensure their longevity and reliability. By following this step-by-step guide, you can identify potential issues and address them before they become major problems, saving you time and money in the long run.

Q: How often should leaf chains be inspected?

A: Leaf chains should be inspected at least once every six months, or more frequently if they are subjected to harsh conditions.

Q: What is the typical lifespan of a leaf chain?

A: The lifespan of a leaf chain varies depending on the conditions in which it is used. However, with proper maintenance, a leaf chain can last anywhere from 5 to 10 years.

Q: Can a damaged leaf chain be repaired?

A: No, a damaged leaf chain should be replaced. Attempting to repair a damaged chain can compromise its strength and reliability.

Q: What lubricant is recommended for leaf chains?

A: A high-quality, industrial-grade lubricant with excellent anti-wear properties is recommended for leaf chains.

Q: Can leaf chains be used in food processing applications?

A: Yes, leaf chains are suitable for use in food processing applications. However, they must be made from food-grade materials and be properly sanitized before use.
