In crane operation, what is the primary purpose of using a spotter?

The primary purpose of using a spotter in crane operation is to enhance communication during lifting. A spotter acts as an additional set of eyes and ears on the ground, providing crucial information to the crane operator about the surroundings, load positioning, and any potential hazards that may not be visible from the operator's perspective. This role is vital for ensuring that lifting operations are conducted safely and efficiently, as effective communication can help to prevent accidents and ensure that the load is moved as intended.

In situations where visibility is limited due to the size of the load or the crane's position, having a spotter helps maintain awareness of the operational environment. The spotter can signal the operator to guide the crane safely, ensuring a smoother operation. Therefore, the enhancement of communication during lifting operations is the key reason for employing a spotter.
