The small testing machine for fatigue tests
While the HA and HB models are floor-standing, allowing equipment assembly at an optimum operating height, the HC models from 10 to 25 kN are table-top models. They can be positioned on a workbench, for example. A concrete base can optionally be supplied as a support. With all HC models the actuator is positioned above the test area, which is equipped with a T-slotted platform.
The test frame features extremely high stiffness, resulting in natural resonance. To avoid unwanted flexural stresses in the specimen the load frames are accurately aligned.
The final element in our dynamic testing product portfolio is the manufacture of all the necessary accessories such as hydraulic power packs, servohydraulic testing actuators, or hydraulic distribution units. Our portfolio is constantly being expanded through a program of continuous development and inclusion of new products, allowing us to satisfy our customer’s most demanding quality requirements while continually improving the quality of our products.

Common fatigue tests
Materials and components may fail prematurely under oscillating loads. For this reason, the behavior of materials under alternating mechanical loading is an important decision criterion, for which the necessary data are obtained through testing.
There are two categories of fatigue in materials testing:
