Lifting system, method for electrical testing, vibration damper, and machine assembly

The invention relates to a lifting system, comprising a piezoelectric actuator (5), a support (15), and a hydraulic stroke multiplier (10) having an input and an output side, wherein the input side of the hydraulic stroke multiplier is connected to the piezoelectric actuator (5), and the output side of the hydraulic stroke multiplier is connected to the support (15). In the method for electrically testing an electronic component, the component is placed on the support of such a lifting system and is lifted for positioning relative to a test contact. The vibration damper comprises such a lifting system. The machine assembly has a machine and such a vibration damper. 本发明涉及种升降系统，其包括压电致动器（5）、支架（15）、以及具有输入侧和输出侧的液压冲程倍增器（10），其中，液压冲程倍增器的输入侧连接至压电致动器（5）并且液压冲程倍增器的输出侧连接至支架（15）。在用于对电子部件进行电气测试的方法中，所述部件被放置到该升降系统的支架上，并且被升降以便为了相对于测试触点进行定位。减震器包括该升降系统。机器组件具有机器和该减震器。
