Zwick hydraulic wedge grips are suitable for static tensile and compression tests, as well as for fatigue tests under pulsating and alternating loading.

• Available in various versions with test loads of 25, 100, 250 and 500 kN.
• Connection is to the existing pressurized oil supply when used with. For use with static materials testing machines a small hydraulic power pack is required.
• Extremely convenient operation - open-sided design allows easy specimen changing.
• Interchangeable jaws are available to suit varying specimen (round and flat) dimensions.
• Adjustable gripping pressure allows 'soft' specimens such as wood and plastics to be tested also.
• Radial jaw-guide prevents undue axial stresses in the specimen.
• Also optionally available for superimposed torsion loading.
