What should be checked first during a routine crane inspection?

During a routine crane inspection, the main switch should be checked first because it is crucial for ensuring the crane's electrical system is safe and operational. The main switch acts as a primary control point that allows the operator to safely shut down the crane’s electrical system before any other inspection or maintenance is performed. This is essential for maintaining safety, as it prevents accidental operation of the crane while the inspection is ongoing, thus protecting both the operator and anyone working nearby.

Checking the main switch first also typically facilitates further inspections because, if any electrical issues are found later, they can be addressed without the risk of the crane being inadvertently powered on. Ensuring the main switch is in the off position is a key step in verifying that the crane can be safely analyzed further, which may include looking at the hydraulic system, electrical connections, or load chain thereafter.
