Endless Wire Rope Grommet Sling

🔹 Description

Endless wire rope grommet slings are fabricated by forming a continuous loop using a single rope or multiple strands without end terminations.

They provide uniform load distribution, high strength, and excellent durability, especially suitable for heavy-duty lifting applications.

🔹 Key Features

  • No end fittings → no weak points
  • Full rope strength utilization
  • High safety factor
  • Suitable for large and heavy loads
  • Excellent fatigue resistance
  • Can be customized (diameter, structure, length)

🔹 Technical Notes

  • Manufacturing diameter range: Φ24 – Φ300 mm
  • For limited lifting height, minimum sling length ≥ 50 × rope diameter
  • Bending diameter ≥ 1.5 × rope diameter (D ≥ 1.5d)
  • Applicable standards: GB/T 30587-2014
  • Safety factor may be increased for offshore or harsh environments
