Maintenance personnel are permitted to operate the crane only when doing what?

Maintenance personnel are permitted to operate the crane while performing their duties because it is essential for them to have direct operational access to effectively carry out maintenance tasks. This operation allows them to troubleshoot, inspect, and ensure that all systems of the crane function properly as part of their job requirements. Their specialized knowledge enables them to handle situations that require immediate attention and to make necessary adjustments or repairs.

While supervision, training, and testing are important aspects of crane operations, the primary role of maintenance personnel focuses on the execution of their specific duties related to the care and upkeep of the crane machinery. Therefore, operating the crane in the line of their responsibilities is a critical aspect of their job that ensures safety and efficiency in crane operations.
