Carry-Deck Crane Practice Test

Why are tag lines used when lifting with a carry-deck crane?

To help control load movement and prevent side sway For decorative purposes To measure distance They are optional and rarely used

Correct Answer:

For decorative purposes

Explanation:

Tag lines are used to control load movement and prevent side sway during lifting with a carry-deck crane. When a load is suspended, it acts like a pendulum and can swing or rotate due to crane motion, wind, or directional changes. Ground crew grab the tag lines and apply gentle, coordinated tension to steer the load, dampen swing, and guide it to the exact set-down point. This helps keep the load away from people, structures, and other equipment, making the placement safer and smoother. Tag lines are a standard safety practice, not decorative or optional, and their use is coordinated with the crane operator.
