Function description

The load-reduction curve with 90° deflection gently reduces the tensile force before the clamping point. Pneumatic clamping ensures constant gripping force with easy, reproducible adjustment. The specimen is held securely and jaw breaks are avoided.

Advantages

  • Secure holding of the specimen ensures reliable test results, even with specimens prone to shrinkage.
  • High specimen throughput thanks to quick specimen insertion and centering via guide groove.
  • The load-reduction curve ensures gentle gripping with no jaw breaks.
  • The jaws can be changed easily for different applications.
  • Interchangeable load reduction curves enable optimum adaptation of the specimen grips to accommodate different specimen materials.
  • In addition, the specimen grip can also be used vertically without load-reduction curve.
  • Two specimen grips in one. Depending on the specimens, the specimen grips can be used with the load reduction curve as well as without it. As a result, optimal gripping is ensured even with alternating specimens.

Pneumatic Control Unit for Specimen Grips

The closing force of the pneumatic grips can be steplessly set via a pneumatic control unit, which ensures safe gripping of a wide range of different materials. The opening and closing of the specimen grips can be controlled by foot switches or via the remote control of the materials testing machine for greater operating comfort.
