Forklift mast chains play a critical role in your equipment’s operation. While the hydraulic cylinders raise the mast rails, it’s the mast chains that raise the carriage and forks. Without properly functioning mast chains, your forklift won’t be able to lift loads, leaving you unable to get the job done.
How Mast Chains Work
Mast chains are attached to the forklift’s carriage and run over a chain wheel, functioning like a pulley system. As the hydraulic cylinder raises the mast rails, the chains lift the carriage and forks to handle loads effectively.
Common Mast Chain Wear and Signs to Watch For
Mast chains endure significant wear from thousands of lift cycles and heavy loads. Ignoring wear can lead to dangerous conditions, including product damage or injuries. As part of your daily forklift inspection, look for these key warning signs:
1. Broken Links: These can result from excessive force, such as dropping a load or working on uneven surfaces.
2. Turned Pins: Lack of lubrication can cause pins to turn, leading to further chain damage. Proper lubrication is essential.
3. Wear or Elongation Over 3%: Chains naturally elongate over time. Use a chain gauge to measure elongation. If elongation exceeds 3%, the chain must be replaced.
Inspecting and Maintaining Mast Chains
It’s important to know that chain designs vary, and different chain pitches have specific limits for wear and elongation. Use a chain gauge with wear guides that correspond to your chain type. If you’re unsure, always consult a technician or authorized dealer for guidance.

Why Professional Maintenance Matters
If you’re unsure about your forklift’s mast chains or notice any of the issues listed above, don’t wait—reach out to a qualified technician. Authorized dealers can schedule planned maintenance to inspect your forklift, replace worn parts, and ensure your equipment operates safely and efficiently.
Stay Proactive and Safe
Your forklift mast chains are vital to safe and productive operations. Regular inspections, proper lubrication, and timely replacements are essential to preventing costly downtime or accidents.
