Type of test

  • Each test requires a test piece gripping device. Only if the clamping and/or testing devices function correctly, can safe and reliable testing be carried out. For this, it is necessary to choose the right clamp for each test.
  • With its wide range of jaws and testing devices, STEP Lab covers the major application ranges for tensile, compression, bending, shear, and cyclic tests.

Specimen shape

  • Thanks to their varied design and operation, the grips are suitable for different shapes, sizes, and materials of specimens and different loads and strain ranges.
  • The specific properties of different materials, such as hardness, strength, ductility, elasticity, and the type of surface are key factors in selecting the right grip.

National standards

  • Standard specifications, as well as general test requirements, play an important role in the selection. For example, with a high specimen yield, the automatic application of clamping force, as required by pneumatic and hydraulic gripping, is necessary.
  • If different types of tests are to be carried out, the grips should have a high degree of flexibility. This reduces the time and cost of changing grips and thus increases operating convenience.

Hydraulic jaws

Hydraulic grippers are mainly used with test loads from 50 kN in combination with high clamping forces.

For uniaxial compression and tension tests – 50kN

For biaxial compression, tension and torsion tests – 200Nm

Dimensioni

Flat: 0 – 8mm

8 – 12,7mm

Round: 3 – 7,8mm

7,1 – 12,7mm

12,4 – 18mm

Pneumatic jaws

Pneumatic vices are particularly suitable for a wide variety of materials, especially those that are sensitive to clamping forces, with minimal changeover effort. The clamping force is generated by pneumatic actuators acting directly on the jaws or by a lever system.

For uniaxial compression and tension tests – 20kN

For biaxial compression, tension and torsion tests – 200Nm

Dimensioni

Flat: 0 – 8mm

8 – 12,7mm

Round: 3 – 7,8mm

7,1 – 12,7mm

12,4 – 18mm

Two and four screws manual Specimen Grips

The screw grips are single-sided. The side screw is used to open and close the grips, and to apply the clamping force before the test begins.

For uniaxial compression and tension tests – 5/60kN

Dimensioni

Flat: 0 – 8mm

8 – 12,7mm

Round: 3 – 7,8mm

7,1 – 12,7mm

12,4 – 18mm

Wedge grips

The manual wedge action grip is designed to facilitate the loading, aligning, and positioning of test specimens. After initial contact with the specimen, the gripping force increases as the test load increases.

For uniaxial compression and tension tests – 50kN

For biaxial compression, tension and torsion tests – 140Nm

Dimensioni

Flat: 0 – 8mm

8 – 12,7mm

Round: 3 – 7,8mm

7,1 – 12,7mm

12,4 – 18mm

Wedge grips

The manual wedge action grip is designed to facilitate the loading, aligning, and positioning of test specimens. After initial contact with the specimen, the gripping force increases as the test load increases.

For uniaxial compression and tension tests – 15kN

Dimensioni

Flat: 0 – 8mm

8 – 12,7mm

Round: 3 – 7,8mm

7,1 – 12,7mm

12,4 – 18mm
