Under what condition may a swivel be used with rotation resistant wire rope?

Always

Never

If the rope manufacturer approves

A swivel may be used with rotation resistant wire rope if the rope manufacturer approves its use. Rotation resistant wire ropes are designed to minimize the tendency to rotate under load. When using a swivel, it is crucial to ensure that it does not compromise the intended functionality of the wire rope. The manufacturer’s approval serves as a validation that the specific swivel can be safely used without negatively impacting the rope's performance or integrity. This is especially important because using a swivel without proper guidance can lead to issues such as rope fatigue or failure, which can jeopardize safety on the job site. Thus, obtaining manufacturer approval is the right approach when considering the use of a swivel with rotation resistant wire rope.
