EHF-L series

Benchtop modification of a fatigue testing machine with top actuator location

The EHF-L series servopulsers are compact, high-performance testing machines specially designed for research and development of new materials. With fully digital control, the reliable and precise multi-functional systems open a new era in the field of fatigue testing of materials. Thanks to the upper location of the actuator, they can be used for testing finished products and quite large samples, despite the relatively low power (max. 20 kN). The machines are optionally equipped with a lower base plate with T-slots. The hydraulic stations QF-10B, QF-20B, AF-4, AF-10B, AF-20B are suitable for this type of frame.

Features

  • Accuracy. The highly rigid main frame, powerful digital controller electronics and a specially developed Shimadzu servo valve ensure accurate testing with high reproducibility of results.
  • Safety. Special safety features and an emergency stop button make the work safe for the user.
  • Continuously variable force and speed. The high-performance servo valve allows for instant changes in test force and speed.
  • Two-stage cross drive mechanism. The hydraulic cross drive and clamp can be operated intuitively using handles. This two-stage configuration helps prevent errors and accidents.
  • Multifunctionality. The system consists of a main frame, controller and hydraulic station. Depending on the user’s goals and tasks, the frame power and the required grips are selected.
  • Compactness The system is designed to use the laboratory workspace as economically as possible.
  • High-rigidity frame and large testing space. The increased rigidity of the main frame guarantees trouble-free operation of the testing machine and also provides reliable fixation.

Areas of application:

These compact benchtop models with a top-mounted drive on an L-type loading frame can perform a wide range of fatigue and endurance tests, from structural elements to finished parts or small components in a variety of materials.

Technical specifications

* Possibility of supplying the machine with movement ± 100 mm
