Product Features:

High-strength hollow shafts secure the upper crossbeam and work surface, forming a highly rigid gantry-frame main unit:

A drive system comprising a servo motor, synchronous belt, pulleys, and precision backlash-free ball screws enables vertical movement of the crossbeam; the testing process is controlled via measurement and control software:

High-precision spoke-type load cell with a force measurement accuracy of Class 0.5;

A comprehensive range of testing fixtures featuring pin connections and simple nut-locking mechanisms for easy operation;

Powerful fully digital closed-loop, multi-channel measurement and control system with built-in testing method standards; automatic control of the testing process; data can be saved, exported, and shared with multiple networked companies;

Modular electrical control cabinet for easy troubleshooting;

Test force overload protection, safety limit protection, overcurrent and overvoltage protection; operational status indicator lights and voice prompts; emergency stop switch included;
