    Servo-Hydraulic Universal Testing Machine, Dual Space, Wedge Action Grip

    The servo-hydraulic testing machine with dual-test-space features a lower-mounted actuator and two fully independent test spaces:

    • Upper test space (between the upper and lower crossheads): primarily used for tensile testing.
    • Lower test space (between the lower crosshead and the test table): designed for compression, bending, shear, and flexural tests.

    Both spaces can be configured by raising or lowering the lower crosshead through a lead-screw system, enabling flexible adjustment to accommodate different specimen sizes and test setups. This testing machine is widely used for tensile, compression, bending, shear, and flexural testing of metallic materials. With appropriate grips, it can also support a broad range of tests on various structural components.

    Yes. The servo-hydraulic universal testing machine combines a high-stiffness load frame with a servo-hydraulic proportional control system, delivering stable and precise force and displacement control under high-load conditions.
    It is highly suitable for mechanical testing of construction steel, cement components, and concrete specimens.

    Absolutely. With a high-response servo valve and a high-precision load cell, the machine delivers full-range force accuracy better than ±0.5% from 1-100% FS. This ensures highly accurate loading control and dependable detection of yield points, strain-hardening behavior, and fracture force.

    Yes. The controller offers three closed-loop control modes (force, displacement, and strain) and supports fully programmable loading sequences. Features such as stress hold, displacement hold, ramp control, and multi-step loading paths enable complex, customizable test procedures, making the system ideal for advanced material research and academic experimentation.
