Abstract (en)
[origin: WO2008084077A1] A hydraulic aggregate for supplying a hydraulic cylinder in consecutive load lifts (LHl, LH2, LH3, LH4) is monitored for its working load in order to determine the state of the aggregate automatically. For this purpose, the time interval of the pressure is determined for each load lift. The pressure and duration are processed into a characteristic number which indicates the wear, making it possible to diagnose the state of the hydraulic aggregate at any time.
