Power System

● It's powered by Dongfeng Cummins 6BTAA5.9-C180 China-II compliant inline, 4-stroke, direct injection, water-cooled, and turbocharged and intercooled diesel engine

● The high torque reserve enables the machine to output stable power under severe working conditions and meet your working needs.


Driving/Riding Environment

● The cab and the main frame are connected by shock absorber to ensure the operating safety and reliability.


Working adaptability

● The integral three-segment drive axle is built internally with imported no-spin automatic limited slip differential to guarantee stable and reliable drive.


Operating performance

● The external gear working device of proprietary technology features high drive torque and strong resistance against external force impact.

● The blade of larger angular adjustment range (37°-83°) improves the material control capability and remarkably promotes the operating efficiency of motor grader, especially during the handling of dry material and clay.

● With full-load scraping capability in 2nd forward gear, the motor grader can remarkably promote the production efficiency compared with domestic products of like type.


Easy maintenance

● The hydraulic pin puller cylinder can complete the operations of swing frame by merely one operator to eliminate all potential safety hazards and ease user’s operations.

● The electric harnesses adopt seamless corrugated pipes and deconcentrators for branching, featuring high protection grade.

This type grader is widely purchased by our clients using for high-way construction project . Highway subgrade is the foundation of road surface and an important part of highway engineering. The subgrade bears the traffic load from the road surface and is the supporting structure of the road surface. It must have sufficient strength, stability and durability. According to the different terrain, the roadbed generally adopts two forms: embankment and cutting.
