The IYH series hydraulic slewing drive comes with low speed and achieves a high torque of up to 200kN.m. It is composed of planetary gearbox, hydraulic motor, pinion, wet type multi-disc brake and valve block. It is designed with compact structure, light weight, and low noise. This slewing drive also features high starting efficiency and maintains good stability when operating at low speed.

Our hydraulic slewing drive is suitable to run even in unfavorable environment. Hence, it is now widely applied in railway, construction machinery, ship, as well as petroleum and mining industry. With a wide range of torque and drive ratio for option, this slewing drive can meet customers' different demands. In addition, tailored solutions with respect to this series of drive are also available.

IYH22C Hydraulic Slewing Drive
IYH22C hydraulic slewing drive has small radial dimension, light weight, large torque, high transmission efficiency, reliable braking, low noise and etc. And its output shaft could withstand a relatively heavy radial load and thrust load.
