The slewing drive usually consists of 2 parts: slewing support and slewing drive. The slewing support device connects the slewing part of the crane with the non-slewing part and provides the constraints required by slewing movement to ensure that the slewing part has particular activity. At the same time, it gives stable support for the slewing part to withstand the vertical load, horizontal load, and overturning moment from the slewing part. The rotary drive device is used to drive the rotary position relative to the non-rotary part to realize rotary movement.
The specifications for slewing drives and gears vary depending on the material the gear is composed of. However, a majority of the drives and gears commonly used are composed of steel and phosphor bronze. According to an extensive series of tests, chill-cast nickel-phosphor bronze ranked first in resistance to wear and deformation.
