50 kN Capstan Grips for Rope


  • Grips especially designed for testing rope
  • A self-tightening action is applied during testing because of split drum and capstan
  • Maximum capacity of 50 kN (11,000 lbf)
  • A range of drum grip faces to accommodate specimens 8 to 28 mm (0.31 and 1.1 in) in diameter

These 50 kN (11,000 lbf) capstan grips are designed specifically for testing the tensile properties of rope with a diameter between 8 and 28 mm (0.31 and 1.1 in). The upper and lower grips incorporate an easy-to-load split drum and the upper grip has a counterweight attached to maintain alignment of the grips with the axis of the universal tester during testing.

A grip set includes upper and lower grips with grooved faces inside the split drum to increase gripping of the specimen. Standard grip faces are for rope with a diameter of 8 to 12 mm (0.31 to 0.47 in). A range of additional drum grip faces is available to accommodate ropes with a diameter up to 28 mm (1.1 in).
