In a range diagram, what can boom length and angle be used to determine?

In a range diagram, the boom length and angle are used primarily to determine the load radius. The load radius is the horizontal distance from the center of rotation of the crane to the center of gravity of the load being lifted. By analyzing the boom length and its angle, operators can accurately gauge how far the load will extend from the crane's pivot point, thus allowing them to establish whether the crane has the capacity to safely lift the load at that specific radius.

Understanding the load radius is crucial for safe crane operations, as it directly affects the lift capacity based on the crane's specifications. A correct interpretation of a range diagram helps operators make informed decisions about the lifting tasks ahead, ensuring safety and efficiency during operations. This knowledge is essential in preventing overloading, which can lead to accidents or equipment failures.
