Abstract (en)
[origin: EP2251299A1] The device has a hydraulic motor (200-1) used as a lift drive, where a hydraulic connection of the hydraulic motor is connected with hydraulic loads (100-1, 100-2, 300-1) such as hydraulic steering and/or hydraulic brakes, via valve seat arrangements in a leak-proof manner. A control device is designed to drive the hydraulic motor in a biased or raised position before the control device is switched off or placed in a suspended state. Each valve seat arrangement has a 3/2 way seat valve between the hydraulic loads and the hydraulic motor. An independent claim is also included for a method for providing pressure reserve in a hydraulic system.
