National Commission for the Certification of Crane Operators (NCCCO) Mobile Crane Practice Exam

Which of the following conditions may warrant a crane inspection?

1. The weather is poor

2. Routine maintenance is scheduled

3. After any modifications are made

4. The operator has changed

The correct answer is: After any modifications are made

Crane inspections are crucial for maintaining safety and compliance with regulations. Modifications to a crane can significantly alter its operation and safety characteristics; therefore, it is essential to conduct an inspection following any modifications to ensure that all safety features and operational components are functioning correctly. This includes inspecting the crane's structural integrity, load capacity, stability, and any newly installed parts or systems that may affect its operation. While poor weather conditions, scheduled routine maintenance, and changes in operator may all influence crane operation and safety practices, they do not inherently require an inspection. Poor weather may prompt a reevaluation of operating conditions, but it does not necessitate an inspection unless specific safety concerns arise. Routine maintenance is typically a planned event, and while regular checks are performed, it does not automatically trigger a formal inspection outside that routine. A change in operator may necessitate a review of operational procedures or training, but it does not require a crane inspection unless the operator's competence or the crane's operational condition is in question.
