There are accidents, and then there are incidents. Accidents are often the results of carelessness: a forklift operator gets too close to a rack and scrapes the paint, a nail in the yard creates a flat tire, someone forgets to charge a forklift’s battery overnight, etc.
Incidents, on the other hand, are severe (usually preventable) problems that make your stomach sink into your shoes. A forklift mast chain failure falls squarely into the incident category.
A mast chain failure will send the forks, carriage and load crashing to the ground. The sudden weight shift can also cause the forklift to tip over and injure the operator. That’s why operators must inspect the forklift’s mast chains before every shift.
This article will cover:
Here’s a quick refresher on mast chains: when an operator pulls the lever to lift a load, hydraulic pressure raises the lift cylinders, which raise the inner mast rails. But the chains are what actually lift the carriage, the forks and the load.
After thousands of lift/lower cycles, chain links will elongate, crack or show other signs of wear. As mentioned above, a weakened chain is a serious safety risk.
Here are the basic things operators should look for during their pre-shift inspections:
Other signs the forklift chain may need to be replaced include:
Annual Forklift Mast Chain Inspections
Have your forklift chain professionally inspected every year or 1,000 hours (in addition to daily inspections). A professional forklift technician can ensure the tension is balanced on both sides and use a forklift chain wear gauge to check for elongation.
A forklift chain with elongation of 2% or more should be replaced. It may not sound like much, but consider this: a forklift chain with 3% elongation has lost 15% of its strength.
In a single-shift operation that’s relatively clean, a forklift’s leaf chains should last three to five years. Dust, chemicals and outdoor operation can shorten this life span.
