What diagram provides information about working quadrants?

The working area diagram is specifically designed to illustrate the various working quadrants of a crane. Each quadrant represents a distinct area in which the crane can safely operate. This diagram is crucial for operators to understand the limitations and capacities of the crane as it varies depending on the direction and distance from the center of the crane's rotation. By studying the working area diagram, operators can identify the safest and most efficient way to operate the crane within those quadrants while taking into account factors such as load capacity and stability.

Other options, while they may provide helpful information, serve different purposes. For instance, operational safety diagrams focus on safety protocols and operational procedures but do not delineate the working quadrants. The load chart provides vital information about the maximum load capacities at different radii and boom angles, which is important but does not illustrate the spatial layout of the quadrants. The outrigger stability diagram pertains to the stability of the crane when outriggers are extended, helping to ensure that the crane remains balanced during operation, but it does not cover the operational quadrants directly. Thus, the working area diagram is the definitive source for understanding working quadrants.
