摘要

The device (1) has a rotating device (2) completely or partially integrated within a natural quick-change unit frame (12), where the frame and a rotating device housing (7) form a unit. A worm wheel (8) of the rotating device projects upward from the housing. A supplementary pivoting device is formed between an excavator retainer (3) and the rotating device such that the pivoting device is in fixed connection with the worm wheel in a downward direction and with the retainer in an upward direction for forming a tilt rotator.
