HA series: 50 to 500 kN

The HA range consists of a classical servohydraulic testing machine with a testing actuator mounted in the lower crosshead. These servohydraulic testing machines are particularly suitable for determining material properties under cyclic loading (fatigue test), e.g. fracture mechanics, LCF (Low Cycle Fatigue).

General fatigue tests are described in DIN 50100. ASTM E466 describes for example fatigue tests on metals, while EN 15630 describes fatigue tests on concrete-reinforcing steel.

• HA servohydraulic testing machines are available in various versions for test loads from 50 to 500 kN.
• Standard testing-actuator stroke is 100 or 250 mm.
• Can be supplied for 210 or 280 bar system-pressure.
• Test frame features extremely high stiffness and natural resonance Extremely accurate alignment of load frames avoids unwanted flexural stresses in the specimen.
• Load cell attached to upper crosshead as standard.
• Adjustable upper crosshead, 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).
