What is the purpose of a tag line during lifting operations?

• A. Tag lines are decorative cords
• B. A tag line provides ground-control over the load to reduce swing and guide placement; it must be operated by trained personnel away from the load path and kept clear of pinch points.
• C. Tag lines are used to measure load weight
• D. Tag lines replace the crane's safety devices

Answer: (B)

Tag lines are used to control a suspended load from the ground, helping to reduce swing and guide the load to its final position. A trained ground person attaches the line to a secure point on the load and communicates with the crane operator to apply gentle, lateral tension. This coordination keeps people clear of the load path and pinch points while steering the load more precisely, improving safety and placement accuracy. Tag lines are not for measuring weight, they aren’t decorative, and they don’t replace the crane’s safety devices—the crane’s safety features stay in effect regardless.
