What does IWRC stand for in rope construction?

• A. Independent Wire Rope Core
• B. Inner Wire Rope Center
• C. Interwoven Wire Rope Core
• D. Independent Web Rope Core

Answer: (A)

Independent Wire Rope Core is the central, separate wire rope inside the outer strands. This core is independent from the outer strands, providing a stable, durable spine for the rope. It improves resistance to crushing when the rope bends around sheaves, helps retain lubrication, and generally yields better performance under high load and heat compared to a fiber core. The other phrases aren’t used in rope construction terminology, so they don’t describe the actual core design.
