Mechanical specimen grips for tensile tests

Mechanical specimen grips

Gripping, clamping, holding - from rough to fragile

Hegewald & Peschke offers a wide range of mechanical grips for tensile tests. This includes both from-fit and force-fit grips, each of which can be used for a wide range of materials, specimen shapes and temperature ranges.

Mechanical specimen grips at a glance:

  • Vice grips
  • Pincer grips
  • Wedge type grips
  • Screw type wedge action grips
  • Specimen holders for shoulder, screw and thread head testing
Tensile test with pneumatic grips

Pneumatic grips

Controlled clamping with compressed air - versatile and efficient

Pneumatic grips are used primarily for tensile tests in a load range of up to 20 kN and for testing specimens that are sensitive to clamping. They enable efficient material testing with convenient operation either via hand or foot switch.

Advantages of pneumatic grips:
  • versatile application possibilities:
    • suitable for testing fibers, foils, paper, textiles, plastics, strips, tapes, wires
    • suitable for materials sensitive to clamping forces
  • high efficiency for testing large quantities
  • constant controllable clamping force over the whole test
  • more cost-effective, lighter and smaller required space compared to hydraulic grips

SWS-300 Laser extensometer

Optical extensometers - Laser extensometer

Deformation measurement with the laser extensometer

The non-contact linear expansion measurement allows the automatic determination of the initial gauge length (L0). The optical system does not influence the measurement with knife edges or its own weight. Laser and video extensometers are used. 

Safety doors

Safety devices

Safe and practical

Each model of the inspekt series can be equipped with a transparent Makrolon safety door. These are essential for some test procedures and materials for the protection of the operating personnel, e.g. in the case of splintering specimens. Depending on the design of the safety door, the various require-ments according to EN ISO 13489-1 can be performed.
