What is the typical role of a signalperson during lifts?

• A. Directly operate the crane's controls.
• B. Maintain the crane's maintenance log.
• C. Provide clear lift signals, coordinate with the operator, and ensure area safety.
• D. Calculate load weight for the lift.

Answer: (C)

The signalperson’s role centers on clear communication and safety during the lift. They act as the ground-based link to the crane operator, using standardized hand signals or radios to tell the operator when to lift, lower, swing, move, or stop. This person plans the lift path with the operator, watches the load and its path for hazards, and keeps the area around the lift clear of people and obstacles. If anything unsafe appears—limited visibility, someone entering the swing zone, or an obstacle—the signalperson stops the lift and communicates the reason so the operation can be adjusted or halted. The signaller is essential because the operator’s view may be restricted, and precise, coordinated movement depends on timely, unambiguous signals. Tasks like actually operating the crane, recording maintenance, or calculating load weight are handled by others, so they are outside this role.
