Product Information Screw type wedge action grips 100 kN and 250 kN Hegewald & Peschke, Meß- und Prüftechnik GmbH Am Gründchen 1, 01683 Nossen, Germany Telephone: +49 35242 445-0, Telefax: +49 35242 445-111 E-Mail: [email protected] http://www.Hegewald-Peschke.com

Scope of application: Screw type wedge action grips are suitable for tensile test on a broad range of materials and specimen geometry. Furthermore, compression and bending tests can be realized via optional connections in the base body. Specimen material:  Metals, alloys  Thermo- and thermosets as well as fiberreinforced plastics  Wood materials  (Geo-) textiles Specimen shapes: Round and flat specimen, e.g.  Strip specimens  Waisted specimens  Round bars  Wires Technical data:  Flat jaws equipped with a specimen stopper  Use of special jaws for special specimen dimensions possible...

Functionality: The opening and closing of the grips is carried out manually by actuating the hand wheels. In addition, the preload is applied thereby. Due to the wedge action of the clamping jaws, the clamping force increases according to the tensile force. 1) Close the grip in the synchronized position. Both clamping jaws are at zero position. 2) Switch to asynchronous mode and open right jaw. The opening distance is determined by the specimen and adhesive thickness. 3) Switch back to sync and close both jaws. Switchable synchronization/ Clamping of asymmetric specimen (only for art.-no. 14-103-100...
