Which items are included in quarterly crane inspections?

• A. Deformation of hooks, excessive wear or twist wire ropes, wear of mechanisms
• B. Annual visual inspection for cracks or stress
• C. Hydraulic oil sampling
• D. Record keeping of maintenance

Answer: (A)

Quarterly crane inspections focus on quickly deteriorating, safety-critical components that can fail with regular use. Inspecting hooks for deformation catches visual and functional signs that a hook might snag, open under load, or break during lifting. Checking wire ropes for excessive wear or twist is essential because worn or twisted ropes lose strength and can fail suddenly, risking dropped loads or snapped lines. Assessing wear of mechanisms targets the moving parts that control operation, ensuring gears, bearings, and other components aren’t slipping, seizing, or misaligning. The other items fit different maintenance timelines or tasks. An annual visual inspection for cracks or stress is typically done less frequently than quarterly, serving as a more in-depth look than the quarterly check. Hydraulic oil sampling and routine maintenance record-keeping are separate activities—either ongoing documentation or specific system tests—not the core focus of a quarterly inspection.
