Abstract:
A hydraulic system (10) for a tiltrotator (13) and an auxiliary tool (14) arranged on a crane arm, excavator or the like, the hydraulic system comprising a pressure supply for pressurizing a hydraulic fluid and a common supply line (15) for feeding the pressurized hydraulic fluid to the tiltrotator (13) and, via the tiltrotator, to the auxiliary tool (14). A diverter valve (16) is arranged at the end of the main supply (15) line close to the tiltrotator (13), which diverter valve (16) diverts the hydraulic fluid into two separate conduits, a first conduit (20) being provided to the tiltrotator (13), and a second conduit (21 ) being arranged through the tiltrotator to the auxiliary tool (14).
