These grips may be used with Instron® E/M systems, MTS® test machines, or virtually any other mechanical test machine – using adapters from TestResources. We supply adapters made to order. Our grip product line includes a wide selection of wedge action grips for static and cyclic tension tests of wires, plastics, metals and elastomers, tensile, static and tension cyclic tests. Mechanical wedge grips feature easy specimen loading, self alignment and centerline sample positioning. Wedge gripping force increases as the pull load goes up, so these self-tightening grips are ideal when high clamp load is needed – such as gripping difficult to hold materials. Wedge style tensile jaws offer a high mechanical advantage by the way they tighten. As the grip body is drawn up, inclined sides push against the matching side of the faces which move laterally against the specimen. The grip faces are spring loaded on the top, against the body. The open front allows faces to be interchanged as well as easy specimen loading. |
