FIELD Engineers was approached by Wesfarmers, to investigate the collapse of a crane during the lowering of a dragline boom during a shutdown which tens of millions of dollars in equipment damage and lost production.
- Expensive dragline downtime meant accident scene needed to be cleared as soon as possible for repairs to begin.
- Investigation required engineers with detailed understanding of crane systems and operation practices.
- Multiple parties involved in project, with differing understanding of responsibilities.
Challenges & Approaches
The site was documented with laser scanning, photographic and video footage with proved invaluable during later analysis.
Extensive investigation and testing of mechanical systems identified the root cause of the incident.
Comprehensive engineering investigation report prepared for future use in litigation.
The 3-D laser scan of the accident scene allowed for accurate reference and analysis which was essential for the forensic investigation and report.
Mechanical analysis and extensive field testing identified root cause of incident which was presented in the engineering investigation report.
Behavioural studies and systems review identified contributory factors for use by mine owner in preventing similar events in the future.
