What action should be taken when visibility is limited and there is risk of load swing?

• A. Continue lifting and rely on operator skill.
• B. Ignore visibility and proceed.
• C. Stop lift and wait for better visibility.
• D. Use tag lines to control load movement and reduce swing.

Answer: (D)

When visibility is limited, the load needs additional, tangible control from the ground crew. Tag lines give a direct means to guide and stabilize the load without relying solely on the operator’s view. By having trained personnel pull and steer at the tag lines, they can dampen swinging motions, keep the load on a safe path, and quickly respond to any unexpected movement. This reduces the chance of the load colliding with people, equipment, or structures, and it improves overall communication and coordination between the crane operator and ground crew.

Relying on operator skill alone isn’t reliable when visibility is poor, and proceeding without visibility or delaying indefinitely aren’t as effective for actively controlling swing. Using tag lines directly addresses the swing risk by providing a controlled mechanical aid, making it the safest choice in this scenario.
