The new tensile wedge grips, that are heavy duty and self-tightening, are now available from IDM Instruments . With a capacity of 1200 lb (5.3 kN) the grips are ideal for a range of tensile testing requirements, when used together with a Motorised Test Stand.
The serrated steel jaws of the tensile wedge grip are opened easily with an ergonomic spring loaded knob and rack and pinion type mechanism. The wedge grip has a thru slot that is suitable for samples of unlimited width.
Instead of sliding along the surface of the housing as with conventional wedge grips, the jaws actually ride on rollers. This prevents jamming and improves the gripping characteristics. Used with a test stand and force gauge the tensile wedge grips create a complete tensile tester system.
