Crane & Heavy Equipment Failure Investigation
When equipment fails, people want answers.
What broke?
Why did it break?
Could it have been prevented?
Who is responsible?
Equipmentdoes not fail "by accident"?
There is always a cause.
What is Equipment Failure Analysis?
Crane & Heavy Equipment Failure Investigation
Crane & Heavy Equipment Failure Investigation
Equipment failure analysis is the process of finding out:
• What component failed
• How it failed
• When it failed
• Why it failed
• Whether the failure caused the incident
This includes cranes, outriggers, booms, wire rope, rigging, hydraulic systems, structural members, and supporting ground systems.
We look at the facts.
Not guesses.
Not assumptions.
Facts.
Common crane Equipment Failures
Crane & Heavy Equipment Failure Investigation
How failure analysis is performed
In crane and heavy construction cases, failures often involve:
•Structural steel cracking or failure
•Hydraulic system malfunction
•Wire rope or rigging failure
•Load chart misuse or miscalculation
•Outrigger or ground support collapse
•Maintenance or inspection deficiencies
•Improper assembly or configuration
Every failure tells a story.
The job is to read it correctly.
How failure analysis is performed
How failure analysis is performed
Failure analysis must be systematic and defensible.
It includes:
• Scene review and documentation
• Photographic and video evaluation
• Review of inspection and maintenance records
• Manufacturer specifications and load charts
• OSHA, ANSI, and ASME standard comparison
• Operational decision analysis
• Evaluation of ground bearing capacity and stability
Opinions are formed only after reviewing the available data and applicable industry standards.
Why Real-World Experience Matters
Equipment does not operate in a laboratory.
It operates:
• On uneven ground
• Under time pressure
• In changing weather
• With real crews
• On active construction sites
Understanding how cranes actually operate in the field is critical to determining whether a failure was mechanical, operational, environmental, or a combination of factors.
Questions Often at Issue
Equipment failure cases often require answers to:
• Was the equipment properly maintained?
• Were inspections performed correctly?
• Was the crane configured properly?
• Did the ground support meet required bearing capacity?
• Did operator actions contribute to the failure?
• Was manufacturer guidance followed?
• Could the failure have been prevented?
These are not checklist questions.
They require technical evaluation grounded in industry practice.
