1 Definition of slewing drive

The slewing drive device is a new type of slewing product composed of a worm gear, a slewing support, a housing and a motor. Since the core part adopts slewing bearing, it can bear axial force, radial force and overturning moment at the same time. Compared with traditional rotary products, the rotary drive has the characteristics of simple installation and convenient maintenance, which saves installation space to a greater extent. This product can be widely used in heavy-duty flatbed trucks, container cranes, truck cranes and high-altitude operations.
