During crane operation, what is the main role of a dedicated spotter?

The main role of a dedicated spotter during crane operation is to ensure safe clearance from obstacles. This is crucial for preventing accidents and maintaining operational safety on the job site. The spotter serves as an additional set of eyes, helping the crane operator maintain awareness of their surroundings, including overhead and side obstacles that may not be visible from the operator's perspective. This role is particularly important in tight spaces or in environments where ground workers and equipment may be nearby. By providing timely and clear communication regarding the proximity of obstacles, the spotter plays a vital role in ensuring that the crane and its load have sufficient clearance, thus preventing collisions and enhancing overall safety during the lifting process.
