What might safely be used to prevent a load swinging when lifted by a crane?
Guide or tag lines tended from a safe location should be used. It is important to properly select tag lines length and location to ensure the angle between the tag line and the deck of not more than 45 deg.
When lifting heavy loads, especially, during rolling and pitching, several tag lines may be required. Tagger winches or capstans may be used as well, if available.
