When the boom angle falls between the capacities listed in the load chart, which capacity should be used?

• A. Higher boom angle gross capacity
• B. Lower boom angle gross capacity
• C. Average of the capacities
• D. Maximum rated capacity

Answer: (B)

When determining the appropriate capacity to use when the boom angle falls between those listed in the load chart, it is essential to prioritize safety by selecting a conservative approach. Choosing the lower boom angle gross capacity is the correct method, as it ensures that the load remains safely within the limits of the crane's stability and operational capability. Using the lower capacity takes into account the fact that as the boom angle increases, the lifting capacity typically decreases due to the changes in leverage and the center of gravity. By opting for this more conservative figure, operators can minimize the risk of overloading the crane, which could lead to potential accidents or mechanical failures. This method aligns with safety protocols and best practices in crane operation, emphasizing the importance of erring on the side of caution to protect both personnel and equipment.
