n: in crane operations, that portion of a wire ropes nominal strength that can be applied either to move or sustain a load without damaging or breaking the rope. The safe working load of a rope is accurate only when the rope is new and the equipment is in good condition. Because most ropes on an installation quickly become used. the safe working load of a rope is also quickly reduced. For this reason, safe working load is seldom used to denote wire-rope strength. See nominal strength.
