Abstract

Bei einer Drehdurchführung für hängende Lasten sind vom Stator zum Rotor führende Hydraulikkanäle für die hydraulische Betätigung eines Greifers vorgesehen. Die stator- und rotorseitigen Anschlüsse für die Greiferhydraulik sind an gegen äußere mechanische Einwirkungen geschütz­ ten Stellen des Stators bzw. Rotors angeordnet. Um zudem einen einfachen, sicheren und schnellen Anbau des Greifers an die Drehvorrichtung zu ermöglichen, sind von oben nach unten durch entsprechende Bohrungen im Rotor hindurch­ greifende Schrauben für die Befestigung des Greifers vorge­ sehen. With a rotating union for hanging loads hydraulic channels leading from the stator to the rotor for the hydraulic actuation of a gripper provided. The Stator and rotor side connections for the gripper hydraulics are protected against external mechanical influences th positions of the stator or rotor arranged. To also simple, safe and quick attachment of the gripper to enable the rotating device are from top to top below through corresponding holes in the rotor gripping screws for fastening the gripper see.
