The angle at which the wire rope approaches the sheave from the drum is called what?

• A. Take-up angle
• B. Fleet angle
• C. Wrap angle
• D. Bend angle

Answer: (B)

Fleet angle is the angle at which the rope comes from the drum and heads toward the guiding sheave. It results from how the drum and the sheave are positioned relative to each other; when they’re inline, the fleet angle is essentially zero, and the rope enters the sheave straight. Offsetting the drum from the sheave causes the rope to approach at a visible angle, which affects how the rope sits on the drum and how it tracks through the sheave. A larger fleet angle increases wear on the rope and components and can lead to unequal winding. This term specifically describes the approach angle; wrap angle refers to how much rope is in contact with the pulley, bend angle to how sharply the rope is bent, and take-up angle is not the standard term for this context.
