What is the definition of load radius?

The definition of load radius is the horizontal distance from the centerline of the crane's rotation to the center of the load being suspended. This measurement is crucial because it directly affects the crane's lifting capacity; as the load radius increases, the capacity to lift decreases. Understanding load radius is essential for crane operators to determine whether they can safely lift a load without risking stability or safety.

In practical applications, knowing the load radius helps operators effectively manage their lifts by considering how far from the crane the load is located. For safety and efficiency, operators refer to load charts to assess the maximum weight they can lift at specific radii. This aspect is paramount in ensuring that lifts are conducted safely and within the crane's operational limits, underscoring the importance of load radius in crane operations.
