Highly dynamic testing of lightweight components
Ratio-Drive® test field equipment
Hänchen handles the system integration with a specially developed safety control system that monitors all components, such as the power unit, cylinder control, control software, etc. This higher-level control system implements a hydraulic shut-down in accordance with EN ISO 13849-1 with Performance Level e (PLe). 

Transport simulations using vibration test stands and shock tests
Ratio-Drive® material test stand

During transport to the customer, the packaging of the goods is sometimes exposed to severe stress. Hänchen designs functional test stands for transport simulation for large mail order companies and logistics companies. Vibration tests and shock tests enable the optimisation of transport packaging.

End of Line test stand for hydraulic products
Ratio-Drive® functional test stand

Hänchen is the specialist for tailor-made hydraulic test stands. On behalf of our customers, we realise EOL test stands for quality control at the end of production. This end-of-line test stand consists of a new, self-developed test field. With the help of the test field, the final inspection for hydraulic cylinders, pressure intensifiers and other hydraulic products is automated and process reliability is increased.

Test stand for seals and rod surfaces
Ratio-Drive® test machine

On behalf of research and industry, we design servohydraulic test stands for seal testing. Our seal test stands simulate a wide variety of operating conditions and provide information on friction force, tightness on rods and shafts, temperature behaviour and seal wear, for example. Depending on requirements, the test stands are implemented electrically or hydraulically.

Large bearing test stand for wind turbines
Hydraulic test cylinder as test actuator

Hydropuls test actuators from Hänchen move one of the world's largest large bearing test stands. Roller bearings for wind turbines with an outside diameter of up to 3,200 mm are tested. The test stands use hydraulic radial and axial cylinders to generate real loads and moments that occur in a wind turbine.

Realistic environmental conditions such as aerodynamic loads, high and low temperatures from -56 °C to +90 °C are simulated in structural test stands for airfoils. Hänchen hydraulic cylinders apply the forces and loads in the test stands for high-lift systems of flaps and slats. Ratio-Clamp® clamping units reliably secure the test stand.

Hydropulse test stand for simulating flight conditions
Ratio-Drive® test stand, test actuator

The DLR developed an "Ironbird" as a test environment for researching new solutions. This is a Hydropuls test stand for the holistic consideration of modern fly-by-wire systems and their subsystems. In addition to an actuator test stand, the test plant also includes a cockpit simulation environment coupled to it.

Servo-hydraulic seat test stand for the automotive industry
Hydraulic test cylinder as test actuator

Servohydraulic life cycle tests are now an industry standard for automotive components, and are used far beyond safety-relevant components. The challenge in designing test facilities such as a seat test stand is to bring together different technologies at the highest level.

The wing tips of the A 340-600 can move more than four metres in turbulence. 94 hydraulic cylinders from Hänchen move the aircraft and are the mechanical core component of a time-lapse test. In the material test stand, the servohydraulic test actuators simulate the movements of an entire aircraft life of 25 - 30 years over a period of 18 months.

Hydraulic cylinders for testing applications
Hydraulic test actuators

Hänchen offers one of the world's largest ranges of hydraulic cylinders for test stand construction. With our two series – the servohydraulic drives of the series 300 and the test actuators of the series 320 – as well as the various seal and guide concepts, we cover all application areas for testing tasks with hydraulic cylinders.

UNIQUENESS

  • We achieve hydraulic cylinders with virtually no friction through our wide selection of seal and guiding systems.
  • Sinusoidal design of the hydraulic drive can be carried out online free of charge using our HäKo configurator.
  • Test cylinders for every frequency range and for high lateral forces.

QUALITY

  • Honed piston rods for good lubrication properties.
  • Designs engineered for continuous load.
  • A carefully selected machine park ensures high production quality.
  • 100% final inspection.
Check box icon blue

COST-EFFICIENT

  • No leak oil pump required for our hydrostatic test actuators.
  • Modular design principle in the 320 series for quick retrofitting of components and adaptation of the cylinder to other nominal forces.
  • Millimetre-precise adjustable working areas enable smaller valves and power units. This saves on acquisition and operating costs.
