IYH22-IYH33 Series Hydraulic Slewing Drives

IYH series hydraulic slewing drives are self-developed with independent intellectual property rights. They mainly consist of hydraulic motors,multi-disc hydraulic brakes, Ctype planetary gearboxes, and distributors. hydraulic motors can choose different distributors according to the working conditions, such as counterbalance valve、overload valve、shuttle valve、speed control directional valve, and another function valve. This series of hydraulic slewing drives featured compact and elegant figures, small sizes and lightweight, high efficiency and power, low noise, and good operating performance. Therefore, the series of hydraulic slewing drives have been widely used in mobile cranes, vehicle cranes, aerial platforms, tracked vehicles, and so on.IYH series hydraulic slewing drives have been well sold in China companies such as SANY, and also have been exported to the USA, Japan, Australia, Russia, Austria, Netherlands, Indonesia, Korea, and other areas in the world.

Model Options:
Options Example:
IYH22A-1500D120221 represents that the hydraulic slewing drives adopt a levels planetary gearbox, and the modules of the gearbox are 2 and 2 respectively, the design code is A, the rated output torque is 1500N.m, the distributor model is D120221.
