When the working radius increases, lifting capacity typically decreases due to the principles of leverage and the distribution of weight. As the boom extends further out from the crane's center of gravity, the load can exert greater torque on the crane. This change affects the crane's stability and lifting capabilities.

The crane's design limits its capacity at different radii to ensure safe operation. As the radius increases, the force required to lift an object at that distance from the pivot point increases, often resulting in a decrease in the maximum allowable load. Thus, operators must consult load charts provided by the manufacturer to determine the safe lifting capacity at varying working radii. Understanding this relationship is crucial for safe and effective crane operation.
