The slewing mechanism usually consists of two parts: a slewing support device and a slewing drive device. The slewing support device is used to connect the slewing part and the non-swivel part of the crane, and provides the constraints required by the slewing motion to ensure that the slewing part has a definite movement, and at the same time provides a stable support for the slewing part to bear the vertical load, horizontal load and overturning moment from the slewing part; the slewing drive device is used to drive the slewing part to achieve slewing motion relative to the non-swivel part.
