Abstract (en)
[origin: WO2006005497A1] The invention relates to a hydraulic control arrangement for damping wagging vibrations. During operation, a hydraulic cylinder (2, 4) of a lifting item of equipment can be connected to a hydraulic accumulator via a damping valve arrangement (18). The damping valve arrangement (18) has a nozzle valve arrangement (54) with two different nozzle cross-sections of which the larger (60) of the two is active when filling the hydraulic accumulator (16), and the smaller (56) of the two is active when matching the hydraulic accumulator (16) with the load pressure of the hydraulic cylinder (2, 4).
