Compacted strand ropes usually have which properties?

• A. Good wear resistance, crushing resistance, and high strength
• B. Poor wear resistance, crushing resistance, and high strength
• C. Good wear resistance, poor crushing resistance, and low strength
• D. Excellent flexibility and very low wear resistance

Answer: (A)

Compacted strand ropes are designed to resist abrasion and crushing while delivering high strength. The manufacturing process packs the strands tightly, reducing gaps and limiting strand-to-strand movement. This produces a smoother outer surface and more even load transfer between strands, which helps the rope resist wear when it slides over pulleys and abrasive grooves. The tighter packing also distributes contact pressure more evenly under load, boosting crushing resistance so the rope holds up better under bending and compression in service. The result is a rope that maintains high tensile strength and lasts longer in demanding rope-guiding and load-bearing tasks. That’s why the option describing good wear resistance, crushing resistance, and high strength is the best fit.
