Emergency Crane Inspections After an Impact or Suspected Overload

Stop the affected work and follow the site's emergency and plant isolation arrangements. Keep people clear of potential hazards and involve the responsible site personnel. If there is immediate danger or injury, use the applicable emergency response arrangements before seeking a technical inspection.

Do not attempt a test lift, repeated operation or improvised recovery to check whether the crane still works. A suspended load or unstable condition needs a competent, site-specific response. This guide is not a recovery procedure or permission to move damaged equipment.

When the site is controlled, contact the emergency crane inspection and assessment service with the known facts so the appropriate inspection and engineering support can be discussed.

Record the time, equipment identity, configuration and what is known about the event. Preserve available logs, photographs and witness accounts when it is safe to do so. Keep observations separate from assumptions about load or cause.

For example, an operator may report an unusual movement without knowing the actual load or whether an overload occurred. Pass that uncertainty to the assessor. An invented load figure can be more misleading than a clearly stated gap in the evidence.

• Crane make, model, serial number, location and current status.
• Configuration, attachments, load information and operating position where known.
• Description of contact, impact, abnormal movement or alarms.
• Photographs and available operational or event records.
• Current isolation, access controls and responsible site contact.

The inspector and engineer may need to consider structural, mechanical, control or supporting-system effects depending on the event. Visual examination may be one stage, with measurements, NDT or further engineering required where appropriate.

An impact at one point can affect connected components or load paths. Conversely, not every incident requires every available test. The competent assessor should define the relevant scope and explain when access or missing information prevents a conclusion.

Separate technical assessment from any incident reporting duties. Notification, preservation and investigation requirements depend on the circumstances and jurisdiction; the duty holder should confirm the applicable obligations with the relevant authority or adviser. An inspection booking does not discharge those duties.

Do not repair, dismantle or alter the affected area without considering evidence preservation and the approved assessment or repair plan. If emergency actions were necessary to control danger, document what changed and why so later interpretation can account for it.

The final pathway may include further investigation, repair, verification, restrictions or a decision that the equipment cannot return to service. Ask for the findings, limitations and outstanding actions in writing. A brief attendance note is not necessarily a complete assessment.

Make responsibility for the owner's return-to-service decision explicit and retain the event history in the asset records. Urgency does not guarantee a favourable result or a particular turnaround. The purpose is a proportionate, evidence-based response to the actual event.
