What does "working radius" refer to in crane operations?

The term "working radius" in crane operations specifically refers to the distance from the center of rotation of the crane to the center of gravity of the load being lifted. This measurement is critical because it helps operators determine the crane's ability to safely lift and move loads. A larger working radius generally results in a decreased lifting capacity, as the weight is further from the crane's pivot point, increasing the risk of tipping or instability. Understanding and calculating the working radius helps ensure that operations remain within the safe limits of the crane's capabilities, promoting both safety and efficiency on the job site.
