(This list is not exhaustive; additional standards can be added as required.)
1. High-strength guide columns secure the upper crosshead and the worktable, forming a highly rigid gantry-style main frame.
2. The transmission system—comprising a servo motor, gearbox, synchronous belt, pulleys, and a precision zero-backlash ball screw—drives the vertical movement of the crosshead, with the testing process managed via dedicated measurement and control software.
3. Equipped with a high-precision spoke-type or S-type load cell, ensuring a force measurement accuracy of Class 0.5.
4. A wide range of comprehensive testing fixtures, utilizing pin connections and simple nut-locking mechanisms for ease of operation.
5. Supports the integration of extensometers, displacement sensors, and large-deformation measuring instruments for precise acquisition of material deformation data.
6. Features a powerful, fully digital, closed-loop, multi-channel measurement and control system. It includes built-in standards for various test methods, enables automated control of the testing process, supports data storage and export, and allows for network integration with external systems.
7. The base of the main frame is equipped with adjustable stainless-steel leveling feet, facilitating equipment positioning and subsequent fine-tuning.
8. A modular electrical control cabinet design simplifies troubleshooting.
9. Includes comprehensive safety features: overload protection for test forces, safety limit switches, and overcurrent/overvoltage protection. The system also provides operational status indicators (via indicator lights and voice prompts) and an emergency stop switch.
