50 kN Capstan Grips for Rope
Shimadzu’s 50 kN (11,000 lbf) capstan grips are designed specifically for testing the tensile properties of rope with diameters 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 align the grips with the loading axis of the test frame.
This grip set includes upper and lower grips with a drum diameter of 180 mm (7.1 in). The grips have alignment grooves on the outside of the split-drum and serrations inside the drum to secure the sample firmly. Standard grip faces are for rope with a diameter of 8 to 12 mm (0.31 to 0.47 in). Additional drum grip faces are available to accommodate ropes with diameters up to 28 mm (1.1 in).

Operation
Specimens are inserted between the upper split-drum, wrapped around the upper and lower drums, and fixed between the lower split-drum. The drums self-tighten as the specimens are loaded to ensure that the samples remain secured in place. Adjust the tension of the spring mechanism to alter the initial clamping force and protect samples.
