When lifting loads with a crane, what key document should operators consult to determine safe boom positioning?

The load chart is a critical document that crane operators must refer to for determining safe boom positioning during lifts. This chart provides specific details on the crane's lifting capabilities, including maximum load limits, boom length, operating radius, and other essential parameters for various boom angles. By consulting the load chart, operators can assess the weight of the load in relation to the boom's position and ensure that it is within safe operating limits, which is essential for maintaining stability and preventing accidents.

While the operator's manual contains important information about the crane’s operation and features, it does not specifically outline load capacities and positioning for particular lifts. Safety guidelines may offer general best practices and standards but lack the specific data needed for individual lifting scenarios. The maintenance log tracks the condition and repairs of the equipment but does not contain any lifting performance information. Hence, the load chart is the most relevant and crucial document that directly addresses safe boom use and load management during crane operations.
