How should operators conduct a pre-operational inspection of a crane?

Conducting a pre-operational inspection of a crane is a critical step in ensuring safety and functionality. Focusing on checking all control mechanisms, safety devices, and fluid levels is essential because it provides a comprehensive assessment of the crane's readiness for safe operation.

By examining control mechanisms, operators ensure that all systems respond correctly and are functioning as intended, which is crucial for safe lifting operations. Safety devices, such as limit switches and guards, must be verified to make certain they are in good working order to prevent accidents. Additionally, checking fluid levels—like hydraulic fluid and oil—helps to avoid mechanical failures that could arise from insufficient lubrication or loss of hydraulic function.

This thorough inspection of multiple components addresses potential hazards before they can lead to serious incidents. In contrast, merely checking mechanical parts or performing a visual inspection from a distance doesn't provide the depth of assessment necessary for safe operation, while reviewing the operation manual alone does not involve a practical check of the crane itself.
