Tyre Handler Clamping Fork Failure

Information:

What

A wheel was being fitted to the right hand inner side (position 5) of a coal hauler prime mover when the shift cylinder failed.

Why

The shift cylinder failure allowed the tyre clamping forks to open, thus dropping the wheel to the ground.

Recommendations

Investigate a change in the design of the tyre changing process to include a secondary locking mechanism and ensure thorough equipment inspection before commencing the job.
