What is one of the main roles of a signal person during crane operations?

One of the main roles of a signal person during crane operations is to communicate with the operator. Effective communication is critical in ensuring safety and efficiency during lifting operations. The signal person serves as the primary link between the crane operator and the surrounding worksite, particularly when the operator does not have a clear line of sight to the load or the area where it is being moved.

The signal person is responsible for using standardized hand signals or radio commands to convey directions, ensuring that the operator is aware of the load's movement and any potential hazards. This communication helps prevent accidents and promotes the safety of all personnel involved in the operation. Proper communication allows for coordination that aligns with the operational plan while actively responding to any dynamic changes on the job site.

The other options involve important tasks related to crane operations but do not capture the primary responsibility of the signal person. For instance, controlling crane speed and securing the load generally falls under the operator's role, and assisting in load rigging is typically performed by riggers and other qualified personnel.
