Electromechanical testing machines CREEP to 500kN. central integrated AC servo drive.

C.X – SPECIAL CREEP TESTING MACHINES FOR LONG-TERM TESTS – Atypical

Electromechanical testing machines of the C.x series CREEP in a vertical four-column design up to 500kN maintaining a constant load by means of a central loading mechanism consisting of a central ball screw and a special mounting of a precision cycloidal gearbox with an integrated AC servo drive. These machines are intended for performing long-term low-cycle fatigue in the I quadrant up to a frequency of 2 Hz, determining crack propagation, creep, stress relaxation in the material, corrosion resistance, etc.
