| description | Disclosed is a hydraulic control arrangement for damping wagging vibrations, wherein during operation a hydraulic cylinder of a lifting equipment can be connected to a hydraulic accumulator via a damping valve arrangement. The damping valve arrangement comprises a nozzle valve arrangement with two different nozzle cross-sections, the larger of which is active when filling the hydraulic accumulator and the smaller of which is active during adaptation of the hydraulic accumulator to the load pressure of the hydraulic cylinder. |
