• To secure the crane boom

Rationale: A tag line is used to control and guide the load during lifting to

prevent uncontrolled swinging.

• Which type of hitch is used when lifting a load with two legs of chain

or wire rope under the load?

• Vertical hitch 1 / 4

• What is the purpose of a tag line’s swivel hook?
• To increase load capacity
• To allow the load to rotate freely without twisting the line
• To lift heavier loads
• To prevent the load from moving

Rationale: A swivel hook prevents twisting of the tag line or load, ensuring

smooth control.

• What type of inspection is required after a sling has been
