1. Brief Introduction

 

The IGY1400～54000T hydrostatic drive series consist of built-in variable displacement piston motor, multi-disc brake, planetary gearbox, and functional valve block. The drives feature high working efficiency, long life, great reliability, compact design, high working pressure and Hi-low speed switch control. The case-rotation type travel drives not only can be directly installed inside the crawler or wheel, but also can be used in road header or milling machine for power turning drives.

 

The drives adopt our patented technology and design experience. The Dimensions and technical performance of the drives conform to Nebtesco, KYB, Nachi, and TONGMYUNG. So our drives can also be used for replacement.

 

The drives described in this catalog are of the standard type. Other design variants with different ratio, dimensions, and power characteristics are available if so requested for specific applications. The drives have been widely applied in crawler excavator, crawler cranes, road milling machine, road header, road roller, track vehicles, aerial platform, and self-propel drill rigs. The drives not only have been used by domestic customer such as SANY, XCMG, ZOOMLION, but also have been exported to Southeast Asia, Middle East, India, South Korea, Netherlands, Germany and Russia and so on.
