HD 8 K and HD 8 K PPI High Performance Steel Wire Rope

Main Properties

  • 8 outer compacted strands
  • Galvanized
  • Regular or lang’s lay
  • Plastic Protected Impregnated core (PPI)
  • High MBL
  • Resistant against drum crushing
  • Flexible
  • Protected core
  • The Plastic Impregnation increases the structural stability

Applications:

When rotation resistant ropes are not required (twin hoist systems with right and left ropes, small heights, etc.). Hoist for steel mill cranes, container cranes, floating cranes and boom hoist for deck cranes, luffing and mobile cranes, grab cranes.

Plastic Protected Impregnated (PPI) core recommended for offshore, deck cranes and marine environment.

  • Tolerance on Diameter: E N: (0; +5%) ; Design Oliveira: (+1%; +4%)
  • Filling factor (f): 8xK12 =0.664; 8xK17=0.670; 8xK26=0.677; 8xK31=0.679; 8xK36=0.679
  • Spinning Factor (k): 1960 N/mm2 = 0.830; 2160 N/mm2= 0.810
  • Modulus of elasticity: E = 115000 N/mm2 (± 5000 N/mm2)

(1) For pure technical reasons, the HD8K Lang's lay are proposed with a conventional core (core with no compacted strands)

ATTENTION:

HD 8 K and HD 8 K PPI must never be used with a swivel.
