Which factor affects the decision on what type of inspection is required for an idle crane?

The duration of idleness is a critical factor in determining the type of inspection required for an idle crane. When a crane has not been in operation for a significant period, various components may be affected by environmental conditions, lack of movement, or potential deterioration. Longer durations of inactivity increase the likelihood of issues that could compromise the crane's safety and functionality.

For instance, lubrication may degrade, mechanical parts may seize, or structural components could be affected by rust or corrosion. Therefore, the specific type and extent of the inspection can vary based on how long the crane has remained inactive, necessitating a thorough assessment to ensure that it is safe and ready for operation before being put back into use.

While the age, make, and model of the crane are relevant considerations in a broader sense, they do not directly dictate the immediate inspection needs related to periods of inactivity.
