Device for performing operation maintenance of hydraulic element, for e.g. hydraulic drive system, has detection unit for acquiring operating condition of hydraulic element based on detection of hydraulic pressure of hydraulic element

摘要

The device (50) has a switching device (52) for cyclically switching ON/OFF of a hydraulic element (40). A detection unit (51) is arranged for detecting the hydraulic pressure of hydraulic element and for acquiring the operating condition of hydraulic element based on detection result. An independent claim is included for a method for performing operation maintenance of hydraulic element.
