After rigging the main hoist line during boom assembly, what must the operator check for proper installation?

The requirement to check the boom angle indicator after rigging the main hoist line during boom assembly is crucial for safe crane operation. The boom angle indicator provides the operator with real-time information about the angle at which the boom is positioned. This information is vital for understanding the crane's stability and load capacity. Correct positioning of the boom ensures that the crane operates within its designed limits and helps prevent potentially hazardous situations such as tip-overs or overloading.

Monitoring the boom angle is essential for load management and effective operation. If the boom angle is not monitored or is incorrectly set, it can lead to improper load distribution, which may compromise the safety of both the operator and those working nearby. Regular checks of the boom angle indicator contribute to the overall safety protocol that operators should follow after any adjustments or rigging.

The importance of this check cannot be overstated, as it acts as the operator's guide to ensure proper operation while handling loads and navigating various lifting scenarios.
