Screw type wedge action grips 100kN and 250kN

Product catalog summary

Product Overview
Hegewald & Peschke offers screw type wedge action grips designed for tensile, compression, and bending tests. These grips are available in two capacities: 100 kN and 250 kN, suitable for various materials including metals, alloys, plastics, wood, and textiles.

Specifications

Capacity: 100 kN and 250 kN
Temperature Range: -20°C to +200°C
Clamping Force Factor: 1.57
Max Opening: 40 mm (flat), Ø 30 mm (round) for 100 kN; 30 mm (flat), Ø 22 mm (round) for 250 kN
Minimum Clamping Length: 38 mm for 100 kN, 45 mm for 250 kN
Dimensions: 192 x 443 x 120 mm for 100 kN, 176 x 452 x 176 mm for 250 kN
Weight: 44 kg for 100 kN, 72.5 kg for 250 kN

Features

Manual operation with hand wheels for opening and closing
Easy jaw change without tools
Low overall height for machine frame integration
Optional motorized drive and torque control device
Adaptable for low/high temperature use

Functionality
The grips utilize a wedge action mechanism that increases clamping force with tensile force. They can be synchronized or operated asynchronously for asymmetric specimens.

Accessories

Clamping jaws for various materials
Specimen depth control stop for large specimens
Handling device for flexible samples
Adapter plates for tool connections

Usage Instructions
For asymmetric specimens, the grips can be adjusted to operate in asynchronous mode, allowing for precise clamping adjustments.

Screw type wedge action grips 100kN and 250kN-2

Hegewald & Peschke MeR- und Pruftechnik GmbH Scope of application: Screw type wedge action grips are mainly used for tensile tests. Compression and bending tests can be realized via optional connections in the base body. Specimen material: • Metals, alloys • Thermo- and thermosets as well as fiber-reinforced plastics • Wood materials • (Geo-) textiles Specimen shapes: Round and flat specimen, e.g. • Strip specimens • Shoulder specimens • Round bars • Wires Functionality: The opening and closing of the grips is carried out manually by actuating the hand wheels. In addition, the preload is applied...

Screw type wedge action grips 100kN and 250kN-3

Changing of clamping jaws by simple insertion: Clamping of asymmetric specimen 1) Synchronized position Switchable synchronization By means of the switchable synchronization, the screw type wedge action grips can tension symmetrically and asymmetrically (for example, tests of shear specimens). The offset is easy to adjust and remains secure even when re-tightened. As a result, a one-hand operation on the left or right is also possible for asymmetric specimen, and the test area is always in the test centre. Accessories: Clamping jaws for various applications • Metals (round and flat specimen)...
