Pneumatic Capstan Grips for Yarn and Cables
Shimadzu’s pneumatic capstan grips are ideal for testing yarn and metal wires. The pneumatic switches promote usability by allowing the operator to actuate the grips while using both hands to pretension the samples. Horned bollards on the upper and lower grips make routing samples easy and encourage samples to fail between the grips by gradually relieving clamping stresses caused by the grip faces.
The pneumatic capstan grips for yarn are available in three capacities: 500 N (11 lbf), 1 kN (220 lbf), and 5 kN (1,100 lbf). Replaceable grip faces are included with the grips. These capstan grips can be controlled with a Foot Valve Unit or C-type Crosshead-linked interlock switch. 500 N capstan grips are only compatible with a Foot Valve Unit.
Additional item needed for operation: External 0.7 MPa (7 kgf/cm2, 102 psi) air compressor.

Relevant Specimens
Cables, Cords
Operation
Mount the specimen by placing it around the horned bollards and thread the loose ends between the grip faces. Actuate the grips using the Foot Valve Unit or the C-Type switch to secure the sample in place. A consistent pretension is easy to achieve using the C-type switch’s spring-loaded lever.

Foot Valve Unit
Shimadzu’s foot valve unit is a two-position pneumatic switch with two pedals and a pressure regulator integrated into the back of the unit. Press the pedal once to close the grips and secure the sample. Press the pedal again to open the grips and release the sample.

Grip force is changeable by air pressure adjusting screw
C-type Crosshead-linked Interlock Switch
The C-type crosshead-linked interlock switch system includes two two-position switches, located on the grips, and a pneumatic control box. The switches enable convenient operation of the grips and promote consistent pre-tensioning due to the spring-loaded design of the bottom switch. The control box connects to the test frame to enable the auto-start, auto-release and return functions for an efficient workflow. These functions can be individually disabled at the user’s discretion.
