Measurements from the center of the crane's axis of rotation to the center of the load line with the load applied is known as?

The term that describes the measurements from the center of the crane's axis of rotation to the center of the load line when the load is applied is known as the load radius. This measurement is crucial for understanding the operational limits of a crane, as it directly impacts the crane's ability to lift a load safely and effectively.

The load radius is essential because it factors into the calculation of the crane's stability and its lifting capacity at differing distances from the pivot point. As the load radius increases, the effective lifting capacity of the crane may decrease due to increased leverage on the crane's structure. Therefore, accurately determining the load radius helps operators ensure safe lifting operations and comply with manufacturer guidelines.

While other terms like hook height, working radius, and lift capacity all relate to crane operations, they refer to different concepts. Hook height refers to the height of the crane’s hook from the ground, working radius is more general and may encompass different aspects of crane operation without specifying the load condition, and lift capacity is the maximum weight a crane can safely lift, which is dependent on factors including load radius but does not define the distance from the rotation axis.
