Abstract (en)
[origin: EP0080670A1] 1. A rotation device for suspended loads, particularly for excavator or crane grabs or lifting magnets, having a stator (1), a rotor (6) pivotably fixed on the stator by means of a roller-contact bearing assembly (4) and which can be driven by a preferably hydraulic drive mechanism (8), characterised in that the roller-contact bearing assembly (4) is designed as a four-point bearing whose running faces (10, 60) for the roller-contact bearing unit (41) are moulded directly into the stator and rotor material and complement each other to form a closed annular space, and in that one of the parts exhibiting the running faces (10) is designed as a threaded ring (13) detachably joined to an outer thread (17) on the associated cupshaped casing portion (12), which incorporates the drive mechanism (8) and is provided with a corresponding counterthread, where the peripheral region of said threaded ring which is accessible from the exterior exhibits a recess (18) for an assembly tool exerting a torque on the threaded ring (13).
