Why are tag lines used during lifts?

• A. To increase the crane's lifting capacity.
• B. To tag the load with identification.
• C. To control the load’s movement and reduce swing, especially when visibility is limited.
• D. To measure wind effect.

Answer: (C)

Tag lines provide a way to physically guide and stabilize a load during a lift. By attaching lines to the load, ground personnel can apply controlled lateral forces to dampen swing, steer the load, and keep it on a safe path, especially when the operator’s view of the load is limited by distance, weather, or obstacles. This teamwork helps the load stay aligned with the hoist line and reach the intended landing spot without swinging into people or structures. Tag lines are about control and placement, not increasing lifting capacity or measuring wind.
