What does the term "lifting radius" refer to?

Lifting radius refers specifically to the horizontal distance between the center of the crane's rotation and the load being lifted. Understanding this concept is crucial for safe and effective rigging operations, as it directly affects the crane's lifting capacity. As the lifting radius increases, the crane's ability to safely lift heavier loads decreases due to the mechanics of leverage and stability.

In practical terms, when the load is positioned further away from the crane, the crane's effective lifting capacity diminishes, which must be taken into account when planning lifts. This ensures that operators do not exceed the safe operational limits of the crane, ultimately promoting safety on the job site.
