Ropes & Rigging FAQs
How do you calculate the fleet angle of wire rope?
Fleet angle is the angle between the wire rope and an imaginary line extending perpendicular to the drum. The fleet angle varies with the distance between the lead sheave and the drum. Using the correct fleet angle of wire rope will ensure your winch is operating at its full capacity and not causing undue wear.
