Leaf chain for secure load handling

Leaf Chain for Secure Load Handling


When it comes to handling heavy loads securely and efficiently, leaf chains are the preferred choice for many industries. Leaf chains are widely used in applications like forklifts, cranes, and hoists due to their high tensile strength and resistance to wear and tear. In this article, we will discuss the common issues related to using leaf chains and various solutions to these problems. We will also guide you through the steps to ensure that your leaf chain is maintained properly and highlight the points that you need to know before using and after using leaf chains.

Why Problems Occur with Leaf Chains?

Leaf chains are expected to perform under high loads, and over time, they can become damaged due to overloading or fatigue. Some of the common issues related to the use of leaf chains include elongation, twisting, breaking, and corrosion. The good news is that these problems can be solved using targeted solutions.

Solutions for Leaf Chain Problems


Elongation is the most common problem that occurs with leaf chains. The elongation of the chain can be due to various factors, such as overloading, incorrect installation, or insufficient lubrication. To prevent elongation, you should ensure that you use the right tension, install the chain correctly, and lubricate it regularly. If elongation still occurs, you can add extra links to the chain or replace it with a new one.

Twisting and Breaking

Twisting and breaking of leaf chains can occur due to poor alignment, improper tension, or inadequate lubrication. It is essential to check the alignment of the sprockets and tension of the chain regularly. If you notice any signs of twisting or breaking, stop the machine immediately and identify the cause of the problem. Once you have found the issue, fix it before resuming the usage of the machine.


Corrosion can happen when leaf chains are exposed to moisture or harsh chemicals. To prevent corrosion, you should use a chain that is resistant to corrosion, paint the chain regularly to protect it from moisture, and avoid using harsh chemicals near the chain.

Steps to Maintain Leaf Chains

To ensure that your leaf chain performs optimally, you need to maintain it regularly. Here are a few steps that you can take to maintain your leaf chain:

  • Check the chain tension regularly.
  • Apply lubrication to the chain as required.
  • Check the chain alignment and sprocket wear.
  • Replace worn-out or damaged chains.

Points to Consider Before and After Using Leaf Chains

Before using the leaf chain, you should check its quality and ensure that it is compatible with the application’s requirements. After using the chain, you should check for any damage or wear and tear. If any damage is found, you should replace the chain immediately. It is also essential to store the chain properly to prevent corrosion and damage to the chain’s links.

Leaf Chain in Use


Q: What is a cotter type chain, and how is it different from a leaf chain?

A: A cotter type chain is a type of roller chain that has a special interlocking system that makes it resistant to shock loads. The cotter-type chains are suitable for use in applications where the load is distributed across the chain’s width. Unlike leaf chains, cotter type chains are not suitable for high-speed applications.

Q: How can I identify the cause of elongation in my leaf chain?

A: To identify the cause of elongation, you should check the chain tension, lubrication, and installation. If the tension is too low or high, the chain will elongate faster. Similarly, if the chain is not lubricated regularly, it will cause wear and tear, leading to elongation. If the installation is incorrect, the chain will be under more stress, causing it to elongate faster.

Q: How long can I use the leaf chain before replacing it?

A: The lifespan of the leaf chain depends on various factors such as the load, speed, and environmental conditions. Generally, a well-maintained leaf chain can last up to 10,000 hours. However, it is essential to check the chain regularly for any signs of wear and tear and replace it if required.

Q: How often should I lubricate the leaf chain?

A: The frequency of lubrication depends on the application’s intensity and the manufacturer’s recommendations. However, in general, you should lubricate the chain after every 100 hours of operation or as recommended by the manufacturer.

Q: Can I use leaf chains in a corrosive environment?

A: Yes, you can use leaf chains in a corrosive environment, provided you choose the right chain and take the necessary steps to protect it from corrosion. You should use a chain that is resistant to corrosion and paint the chain regularly to protect it from moisture. You should also avoid using harsh chemicals near the chain.
