Hydraulic Wedge Grips

BISS AC-05-XXXX Series hydraulic wedge grips are intended for both static and dynamic testing in tension, compression as well as tension-compression. Hydraulically activated wedge action ensures uniform and axially aligned gripping of both flat and round test coupons as well as to hold test fixtures.

Required equal pressure to both grips is set by means of pressure regulating valve on the service manifold. Gripping is activated from the operator touch screen panel. These grips are suitable for use on electro mechanical machines when configured along with a dedicated pump and service manifold unit. Pressure line accumulators and non-return valving ensure retention of gripping force in the event of power outage.

Side mounting design allows safe handling and easy insertion of specimen. A wide variety of wedges is available to suit practically every standard specimen geometry. Custom wedge designs can be ordered to suit specific specimens and materials. Removable screw-on/screw-off handles are provided for easy mounting and dismounting. In addition, special provision is made for other gripping assemblies to be threaded directly onto the grip axis to avoid grip removal.
