Crane idle for one month but less than six months should be given what type of inspection?

• A. Frequent
• B. Initial
• C. Special
• D. Routine

Answer: (A)

When deciding which inspection type to use, you match it to how long the crane has been out of service and what risks that downtime creates. If a crane has been idle for a period, you want to verify that nothing has deteriorated during storage and that it’s safe to put back into service. A frequent inspection is designed for catching issues that can arise from both regular use and downtime, and it’s the kind of check you do to confirm the crane is ready before resuming operation after a short to moderate pause.

Since the crane has been idle for one month but less than six months, a frequent inspection is the appropriate choice to ensure there are no hidden problems like lubrication settling, corrosion, or brake/gear issues that could affect safe operation. An initial inspection is for new installations or after major changes, a routine inspection is a regular maintenance check at defined intervals, and a special inspection is used after unusual events or suspected major problems.
