FEATURES
EHF-E Series
- For Dynamic and Fatigue Testing of Various Materials and Small Parts: E series features an E-type frame with a bottom-mounted actuator, which can satisfy a wide variety of dynamic and fatigue testing requirements, from fatigue testing of materials to evaluating the performance of components.
- Dynamic Capacity Rating of Actuators 50 kN / 100 kN / 200 kN: This series is capable of static, dynamic, and fatigue testing of a wide range of materials, from plastics to aluminum, composites, and steel.
- High Rigidity and Large Testing Space: The large testing space supports material fatigue testing in a high-temperature or thermostatically controlled environment, thermal fatigue testing, fracture toughness evaluation, component performance and endurance testing, and so on. Accessories for respective tests are available. These include grips, compression plates, extensometers, and testing environmental control systems.
- Dual-Stage Crosshead Drive Mechanism: The hydraulic crosshead drive and hydraulic clamp can be operated more intuitively using handles. This dual-stage configuration helps prevent operating errors and accidents.
