Question: 1 / 400

What is the significance of a crane's load radius?

It indicates the maximum height the crane can operate

It determines how far the crane can safely lift a given weight

The load radius of a crane is crucial because it directly influences the lifting capacity and operational safety of the crane. The load radius refers to the horizontal distance from the center of the crane's rotation to the load being lifted. This measurement is significant since as the radius increases (meaning the load is positioned further away from the crane’s base), the lifting capacity typically decreases. Therefore, understanding the load radius helps operators ensure that they are not exceeding the manufacturer's specifications regarding weight limits, which can lead to unsafe situations or tipping hazards. Adequately assessing the load radius allows operators to plan lifts effectively, prioritize safety, and optimize crane performance throughout the lifting operation.
