Mechanical specimen grips Gripping, clamping, holding — from rough to fragile Hegewald & Peschke offers a wide range of mechanical grips for tensile tests. This includes both from-fit and force-fit grips, each of which can be used for a wide range of materials, specimen shapes and temperature ranges. Vice grips External tensioning + Symmetrical and asymmetrical clamping + Light + Adjustable clamping force — For small forces — It is difficult to reach reproducable clamping forces — Clamping force decreases during testing — For polymers (thermoplastic, duroplastic), foils, food,… — Up to 20 kN Pincer grips Self-tensioning — Only symmetrical clamping possible + Light — Clamping and pre-clamping force cannot be adjusted • Clamping force increases during testing — For elastomers, plastics, textiles — Up to 20 kN Wedge type grip Self-tensioning — Only symmetrical clamping possible — Heavy — Clamping and pre-clamping force cannot be adjusted + Up to high forces — Spring back after brittle fracture • Clamping force increases during testing — For metals — Up to 600 kN Screw type wedge action grips External tensioning + Symmetrical and asymmetrical clamping — Heavy + Adjustable clamping force (Reproduceable clamping forces can be reached with a torque wrench) + Up to high forces + Frictional fixation after fracture • Clamping force increases during testing — For metals — Up to 250 kN
