Hydraulic Planetary Gearbox

Our IY series hydraulic planetary gearbox is a kind of shaft mounted low speed high torque planetary gearbox. It has a broad range of torque and drive ratio available, so customers can select the suitable one according to their actual needs. In addition, we can also provide tailored solutions to meet customers' special requirements.

The hydraulic planetary gearbox comes with compact design and light weight. It can achieve high torque up to 200kN.m and high starting efficiency. Its output shaft can bear large external radial and axial load. Moreover, this transmission runs stably even at low speed and produces low noise during working.

Because of the above mentioned advantages, our hydraulic planetary gearbox can be commonly found in the mechanical equipment used in construction engineering, railway, road, ship, petroleum, coal mine, metallurgy industries. It is not only popular in Chinese market, but also sells well in international market, such as UK, Singapore, India, Korea and Netherlands.
