When determining the proper boom angle, applying the load is crucial because it reflects the real working conditions under which the crane will be operating. The boom angle affects how the crane supports the load, its stability, and the overall safety of the operation. By factoring in the actual load, the operator can accurately assess the stresses and strains involved, which aids in making informed decisions regarding the safe lifting and positioning of loads.

In practice, load charts provided by the crane manufacturer are based on specific boom angles and the loads applied. These charts help determine the maximum capacity of the crane, ensuring that it operates within its designated limits. Therefore, having the load applied during the evaluation ensures that the boom angle selected does not exceed the crane's lifting capacity, thereby enhancing safety and performance.

While testing or operating under the assumption of a load is important, relying solely on hypothetical situations or the operator's confidence without confirming the effective load limits could create dangerous circumstances. Hence, applying the load during the assessment is the most reliable approach to ensure safe and effective crane operations.
