The operating radius of a crane is typically measured with what?

The operating radius of a crane is typically measured with a loaded boom because this measurement reflects the actual conditions under which the crane will be working. The operating radius is defined as the horizontal distance from the center of rotation of the crane to the load being lifted at the end of the boom. When assessing the operating radius with a loaded boom, it's important to account for the weight and the distribution of the load, as these factors influence the crane's stability and lifting capacity.

Using a loaded boom provides a more accurate depiction of the crane's capabilities, allowing operators to ensure safe lifting practices and adhere to manufacturer specifications regarding maximum load weights at various radii. This consideration is vital in preventing accidents and ensuring efficient crane operations. Thus, measuring the operating radius with a loaded boom aligns closely with real-world scenarios, where the crane's performance and safety must be fully evaluated.
