NCCCO Mobile Crane Test 2025 – 400 Free Practice Questions to Pass the Exam

The operator can leave the crane only after securing it properly. This means ensuring that all necessary safety measures have been taken before vacating the crane, such as lowering the boom, ensuring no load is suspended, and engaging all safety mechanisms. Proper securing of the crane minimizes the risk of accidents or unintended movements, protecting both the operator and any personnel in the vicinity.

While other options highlight important aspects of crane operation—like the importance of checks, ensuring the load is down, and completing a lift—none of these actions alone ensure the safety and stability required before leaving a crane. The focus on securing the crane addresses the critical need to prevent any potential hazards that could arise if the crane remains in an unsecured state. Therefore, the correct answer emphasizes the importance of safety in crane operations.
