The drag chain wheel is used to prevent the crawler from sagging and falling off when the crawler is walking, and can reduce its up and down vibration function. Based on precise accessories, careful heat treatment and wear-resistant oil seal system, good internal oil circulation system ensures the service life of the wheel. The surface hardness of the supporting sprocket is HRC45-55, and the depth is 3-6mm.

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.

The travel gearbox uses hardened gears and high-frequency-treated ring gears, and the production process is of high quality, thus ensuring a very good load-carrying capacity, reliable operation, low noise and low cost.
