Who must check repairs or resolution checks on crane equipment?

The correct choice emphasizes the need for a qualified person to check repairs or resolution checks on crane equipment. A qualified person is someone who has the necessary education, experience, and knowledge to understand the specific repairs or issues related to the crane. This individual is capable of assessing the effectiveness and safety of the repairs performed, ensuring that the equipment meets operational and safety standards before it is put back into service.

Having a qualified person perform these checks is vital as it helps to prevent potential accidents that could arise from improper repairs or a lack of understanding of the equipment's operational limits. This role involves a deep understanding of the crane's mechanics, how various systems interact, and the implications of any repairs made. Although other personnel, such as the crane operator or maintenance team, may have roles in the overall maintenance and operation of the crane, only a qualified person possesses the specialized knowledge necessary to formally certify that repairs have been adequately completed and that the crane is safe for use.
