Motor Grader

The motor grader, also known as road grader, is a primarily machine used in the construction and maintenance site like dirt roads, gravel roads, as well as snowy and loosen earth. The road grader machine is used to flatten the surface, so that the asphalt can be placed on. It is a preparing base construction course. Road grader is also used to set native soil foundation pads prior to the construction of large buildings. Our motor graders are designed under world-class standards with advanced electronics and hydraulics from 165HP to 315HP for multi-applications. They are equipped with original Cummins engine QSM-11, original ZF torque converter, gearbox and driving axle, or CAT licensed engine, good quality axle, Germany ZF licensed sing-handle electro-hydraulic. It is the ideal product to meet the harsh road construction and maintenance at mining area.

1.The efficient and environment-friendly Shangchai engine is equipped with hard, reliable and secure parts.
2.Electro-hydraulic control power gearshift gear-box is adopted and it's controlled by single lever.
3.The rear axle is equipped with self-locked and off differential mechanism. Inner the balance box is the circular chain drive of reinforced double row roller chain. 17.5-125-12PR wide tyre is a standard one.
4.The motor grader adopts full-hydraulic system, high steering angle, and minimum turning radius prior to same kind of domestic products.
5.The gear oil pump supplies oil to two pilot valves by diverter valve. In rotary oil-way, the oil interflows. The process promotes stable working speed and low energy consumption.
6.The hydraulic locks are fastened to the lifting, sidesway, frame articulating and front wheel sidesway circuits.
7.The structure is U section with A shape. It's simple and with high mechanical strength. The shovel blade can title 90o and the gear ring can rotate 360o.
8.The brake system is hydraulic shoe brake. Brake booster is key part, made from MICO.
9.Unique upturning shield is easy to maintain.
