What is the swing radius of an excavator?

The swing radius of an excavator refers to the circular area that the upper structure can move in. This radius is crucial for understanding the spatial requirements of the machine during operation. The swing radius is determined by the distance from the center of the excavator's rotation to the outermost point of the upper structure, including the boom, arm, and bucket.

Understanding the swing radius is essential for safe and efficient operation, as it helps operators gauge how far the machine can reach while working. This knowledge is particularly important in congested workspaces where there may be obstacles or other equipment nearby. A clear awareness of the swing radius allows operators to maneuver the excavator without risking collisions or damage to the machine or surrounding structures.

In contrast, the other options describe aspects of the excavator's functionality but do not accurately represent the concept of swing radius. The operational capabilities like the distance the arm can swing, the maximum height, or the depth of the bucket relate to different components of the excavator's performance rather than the spatial dynamics of the swing radius itself.
