• Nominal Tensile Strength (MPa): 1570, 1670, 1770, 1870

• Minimum Breaking Load (KN): The load at which the rope breaks, categorized by:

  • Fiber Core (FC)

  • Steel Core (IWR / IWS)

3. Core Types

• NF: Natural Fiber Core

• SF: Synthetic Fiber Core

• IWR: Independent Wire Rope Core (Steel)

• IWS: Independent Wire Strand Core (Steel)

• FC: Fiber Core

4. Calculation Note (from the footnote)

• Minimum Breaking Force Sum: Minimum Breaking Load × 1.226 (for Fiber Core) or × 1.321 (for Steel Core).

Example of Data Points (Diameter 3mm):
