How should a crane operator account for boom deflection while lifting?

• A. Lower the boom angle slightly
• B. Raise the boom angle a degree or two before hoisting
• C. Adjust the load weight
• D. Increase the swing speed

Answer: (B)

When lifting with a crane, boom deflection is a critical factor that the operator must consider. Boom deflection occurs due to the weight of the load and the forces acting upon the crane’s boom during operation. To account for this deflection, raising the boom angle slightly before hoisting is an effective strategy. By adjusting the angle in this manner, the operator ensures that the load's center of gravity and the overall stability of the crane are maintained during the lift. Raising the boom angle allows for better control and can help minimize the effects of flexing on the boom, which is particularly important in maintaining safe operating limits and preventing any potential structural damage or accidents. This proactive adjustment can lead to a safer lifting operation by compensating for the anticipated deflection that may occur as the load is lifted. It's essential for crane operators to understand and anticipate how adjustments in the boom angle can influence the behavior of the crane and the stability of the load. This understanding contributes to effective load management and safety on the job site.
