Servohydraulic fatigue testing machine
max, 500 kN | Model HA Zwick

The HA range are classical servo-hydraulic testing machines, with a testing actuator mounted in the lower crosshead. They are particularly suitable for determining material properties under cyclic loading e.g. fracture mechanics, LCF (Low Cycle Fatigue).

- Available in various versions for test loads from 50 to 500 kN.
- Standard test actuator stroke is 100 or 250 mm.
- Can be supplied for 210 or 280 bar system pressure.
- Load frame features extremely high stiffness and natural resonance. Extremely accurate alignment of load frames avoids unwanted flexural stress in the specimen.
- Load cell attached to upper crosshead as standard.
- Upper crosshead is adjustable, with optional hydraulic crosshead clamping and lift cylinders.
