Which device helps control rotation and prevent sudden moves during lift operations?

• A. Tag lines
• B. Winch brake
• C. Counterweights
• D. Outriggers

Answer: (A)

Controlling how a load moves in the air comes down to actively restraining and guiding it as it is lifted. Tag lines provide a direct, hands-on way to do that. By attaching lines from the load to ground personnel or fixed points, you can apply controlled, directional forces that limit Swing and rotation, keep the load oriented with the crane’s intended path, and help prevent sudden moves. This teamwork between the operator and the tag line handlers helps maintain stability, especially in windy conditions or when the operator’s view is limited.

Other options serve different roles: a winch brake controls rope movement and rate of hoisting or lowering, not the load’s direction in space; counterweights balance the crane to prevent tipping, not the load’s rotation; outriggers widen the base for overall stability, not load control during the lift.
