Dual-Action Hydraulic Wedge Grips for High-Force Tensile Testing

Description

Dual-action hydraulic wedge grips are used for high-capacity tensile testing where stable clamping and controlled jaw movement are required. In side-action mode, the jaws close from both sides under hydraulic pressure, providing even clamping across flat or wide specimens. This helps maintain alignment during loading.

In wedge-action mode, angled jaw slides increase gripping force as the tensile load rises. This configuration supports large metal specimens, steel rods, fasteners, and other high-strength materials used in structural or industrial applications. The hydraulic system allows pressure to be set before the test, supporting consistent specimen engagement.

These grips are used with servo-hydraulic universal testing machines in construction materials labs, metal processing facilities, and industrial manufacturing environments. Their heavy-duty construction supports high load capacities, making them suitable for testing rebar, bolts, and structural metals under elevated tensile forces.
