Haenchen's hydraulic test actuators are efficient with varying test setups, compact, versatile, quick, sensitive and robust – the best choice for challenging tasks.

Perfect for highly dynamic industry and test tasks

  • Industrial applications – from friction welding and ingot oscillation to compacting sintered metal
  • Checking the functional safety of systems, component parts or products
  • Structure test of aircraft, automobile exhaust systems, refrigerating compressors and many more
  • Load and movement simulation, e.g. operational profiles and flight profiles


For every frequency range and for high lateral forces: The test actuators convince with their stability and high inherent stiffness. They are suitable for high speeds and can reliably bear high lateral forces.

Modular system for efficient change of applications: Mounting parts und accessories such as spherical rod eyes, integrated position transducers, force transducers, mounting plates, accumulators or control valves fit cylinders with different forces and do not have to be purchased several times for one test field.

Operation without leak oil pump: Thanks to the elaborate sealing and guiding system, Hänchen cylinders don't need leak oil pumps. Hänchen Series 320 actuators for test applications are equipped with high-quality bronze coatings for optimum emergency running properties. Unlike other hydraulic test actuator manufacturers and the earlier PL and PLF hydropulse actuators from Schenck.

Protection against unforeseen movement: The emergency cushion serves for self-protection of the cylinder and test specimen, and is included in the stroke as standard. The effective stroke is between the two emergency cushioning.

Bores adjustable to the millimetre: The working areas can be designed individually for the respective requirements. This saves acquisition and operating costs for the required periphery and increases the energy efficiency, e.g. with regard to the system's energy input and cooling power.
