What should be the first step during a daily inspection of an overhead crane?

The first step during a daily inspection of an overhead crane should be checking the main switch. This is crucial because it ensures that the crane can be powered on and off safely and that all electrical systems are functioning properly. Confirming that the main switch operates correctly helps prevent any potential electrical hazards before further checks are conducted, making it a foundational step in ensuring operational safety.

Once the main power is verified, the operator can then proceed to check other critical components like load capacity, hoist mechanism, and the emergency stop system with the assurance that the crane is safely powered. Checking the main switch first establishes a baseline for safe operations and allows for a systematic inspection of all subsequent parts of the crane.
