Which two drum types are used for winding wire rope?

• A. grooved drum and plain drum
• B. Grooved drum and smooth faced drum
• C. Round drum and square drum
• D. Cone drum and spiral drum

Answer: (B)

Winding wire rope onto a drum needs both guidance of the rope path and a surface that suits how the rope sits as it winds. Grooved drums provide channels that keep each turn in line, preventing turns from overlapping or drifting into adjacent layers. This keeps the wind neat, reduces the chance of kinking, and helps manage multiple layers as the rope layers build up on the drum.

A smooth faced drum offers a flat surface for the rope to sit on when you want to minimize groove-induced wear or when winding in a single layer or under conditions where a flat contact surface yields gentler, more even rope contact. The rope still winds correctly, but without the confinement of grooves, which can be desirable in certain winding arrangements.

Other drum types listed are used for specialized shapes or applications and aren’t the standard choices for typical wire rope winding.
