How can the wind blowing against the load affect the crane?

• A. It can make it difficult to move the crane, affect the load radius, and decrease capacity
• B. It has no effect
• C. It improves crane efficiency
• D. It only affects operator visibility

Answer: (A)

Wind against the load adds a horizontal push on the load and the lifting line, changing how the crane bears the weight. That extra force creates a larger moment on the crane and can cause the load to swing or drift, which makes moving and positioning the crane more difficult. It also alters the load’s line angle, effectively changing the geometry of the lift and the perceived load radius. Because crane capacity is rated for specific wind conditions and load-line configurations, the added wind force reduces the safe working capacity. So wind against the load can complicate movement, change the effective radius, and decrease capacity. Wind also doesn’t improve efficiency or only affect visibility; its main effect is on stability and safe lifting.
