What is a tag line and why is it used?

• A. A tag line is a load-bearing rope attached to the load to steady it.
• B. It’s used to measure load weight.
• C. It’s used to lift from behind.
• D. A tag line is a non-load-bearing rope attached to the load to control sway and guide the load, kept away from hazards.

Answer: (D)

A tag line is a non-load-bearing rope attached to the load that is used to control sway and guide the load during lifting, kept away from hazards. This means it doesn’t contribute to supporting or lifting the weight; instead, a ground crew member manages it to steer the load, especially when visibility is limited or the load is near obstacles. Because it isn’t part of the lifting force, the crane’s main lines carry the weight, while the tag line provides directional guidance and helps prevent the load from swinging into people, structures, or other dangers. It’s not for measuring weight, and it’s not used to lift from behind; its purpose is control and safe positioning.
