Model HA: 50 to 500 kN

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.
• HA series is the preferred choice for high-temperature testing. 
• Testing system can be tailored to customers' individual requirements (e.g. specimen grips, test fixtures, extensometers or testing software).
