Creep Testing Machines for Quasi-Dynamic Cyclic Testing

---

 

 

The C.5 series electromechanical CREEP testing machines, featuring a vertical floor-standing design with capacities of up to 250 kN, are designed for quasi-dynamic cyclic testing and long-term testing applications. 

 

Precise constant load application with the possibility of cycles up to 2 Hz is ensured by a central loading mechanism consisting of a ball screw and a specially mounted precision cycloidal gearbox with an integrated AC servo drive. 

 

These machines are suitable for both classical and advanced creep testing, stress relaxation testing, and related applications under stable, homogeneous temperature conditions in a high-temperature furnace. They deliver reliable results even after 10,000 hours of continuous loading, requiring maximum precision in force control and axial alignment.
