Cracked Under Pressure: Why Preventative Maintenance Matters

Cracked Under Pressure: Why Preventative Maintenance Matters

In the overhead crane industry, it’s often the smallest parts that can cause the biggest problems. Take this load chain sprocket, for example—a component pulled from a manual chain hoist while doing annual inspections. At first glance, it might look like just another piece of hardware. But a closer look reveals a critical failure: deep cracks running through the core of the sprocket teeth and hub.

This isn’t just a cosmetic issue—this is a red flag for imminent failure.


🔍 What Went Wrong?

The sprocket, also known as a load sheave, is designed to guide the load chain through the hoist smoothly. When it begins to crack, it can lead to:

  • Chain misalignment

  • Jerky or uneven lifting

  • Complete mechanical failure

  • And worst of all—a dropped load

Cracking like this is typically the result of:

  • Overloading the hoist

  • Lack of regular maintenance or lubrication

  • Extended service life without replacement

  • Poor inspection practices


⚠️ The Real Risk

Had this sprocket not been identified and removed, it could have resulted in a serious incident on site. In the worst-case scenario, the chain could have jumped or jammed, causing a dropped load—a life-threatening hazard in any industrial environment.

This is a clear example of why routine inspections and maintenance are non-negotiable.
