After a modification, which professional should thoroughly check the crane?

• A. Compliance officer
• B. Qualified engineer
• C. Certified consultant
• D. Competent person

Answer: (B)

After a modification, the crane must be evaluated by someone with formal engineering expertise because changes can alter strength, load paths, and safe operating limits. A qualified engineer has the training to perform the necessary calculations, assess the structural impact of the modification, ensure compliance with applicable codes and standards, and determine whether the crane’s rating needs to be re-rated or re-certified. They can provide stamped drawings or an engineering evaluation and ensure proper labeling and documentation before the crane is reintroduced to service. Other professionals have important safety and regulatory roles, but they do not perform the engineering analysis and sign-off that a modification requires. The operation should resume only after the modification has been thoroughly checked and approved by a qualified engineer.
