7 Crane Inspection Mistakes That Put Sites at Risk

Overview

Crane inspection planning can be undermined by visual walk-arounds, incomplete records or work performed outside the required scope.

These are common crane inspection mistakes and practical reasons to obtain appropriately scoped professional advice.

The Most Common Mistakes

• Treating a pre-start check as an inspection — daily checks never replace periodic and major inspection under AS 2550
• Skipping NDT on critical welds — fatigue cracks start below the surface where the eye can't see
• Relying on age alone instead of reviewing the major-inspection timing against manufacturer instructions, service history and applicable requirements
• Ignoring wire rope discard criteria — broken wires and reduced diameter have strict limits
• Assuming a repair 'looks fine' — unassessed weld repairs can be weaker than the original defect
• No documented inspection history — missing records make it difficult to demonstrate what was examined and when
• Using personnel without qualifications appropriate to the required scope or method

What These Mistakes Cost

A dropped load or structural failure is the worst case, but unplanned downtime, repair cost and disrupted operations can also follow when defects are found late.

Inspection responsibilities vary with the plant, jurisdiction, manufacturer instructions and applicable requirements. The responsible duty holder should confirm the required scope and competence.

Why Use an Appropriate Inspection Scope

• Suitable NDT methods can find relevant surface or subsurface indications that visual checks may miss
• Inspection scope can reference AS 2550 and AS 1418 where applicable
• Clear written reports with defect photos, locations and recommendations
• Engineering input can support repair or assessment decisions where required
