Which option lists all four basic configurations of wire ropes?

• A. Rotation resistant, Regular lay, Lang lay, Alternate lay
• B. Rotation resistant, Regular lay, Lang lay, Short lay
• C. Rotation resistant, Regular lay, Lang lay, Non-rotating
• D. Regular lay, Lang lay, Alternate lay, Short lay

Answer: (A)

Understanding how wire rope strands are laid out helps predict how the rope behaves under load. The four basic lay configurations typically discussed are rotation-resistant, regular lay, lang lay, and alternate lay. Rotation-resistant rope is built to minimize twisting under load, which helps prevent unwanted rope rotation in service. Regular lay means the strands wrap in the same direction as the rope’s overall twist, giving stable torque characteristics. Lang lay reverses the strand wrap relative to the rope lay, making the rope more flexible and sometimes affecting wear patterns. Alternate lay combines different directions between adjacent strands, reducing snagging and balancing torque. The correct option includes all four of these configurations—rotation-resistant, regular lay, lang lay, and alternate lay—so it accurately represents the four basic configurations taught for wire ropes. The other choices mix in short lay or omit a configuration, so they don’t cover all the foundational lay types.
