 XuGong GR300 motor grader

Power system:
The power system of excellent performance adopts QSL9 turbocharged diesel engine, and takes the technology of electronical injection and electronic throttle, and features high reliability and fuel economy, low emission, and meets the requirement of European and American Emission Standard.
Transmission system:
The advanced reliable transmission system adopts the electro-hydraulic controlled Z F power-shift gearbox, which makes the operation flexible and convenient. The rear axle is three-way drive axle, and the imported self -locking differential is equipped inside; the final drive in the balance box adopts heavy roller chain, which features reliable and stable transmission, and larger swing angle of the balance box to adapt the tough working condition.
Front wheel drive:
The front wheel hydraulics assists to drive. The front wheel can be set to drive wheel or free wheel according to the working condition, to carry out 6-wheel, 4-wheel and 2-wheel drive. The adoption of front wheel auxiliary drive greatly extends the grading area of the grader especially in the tough condition (for example muddy and snowy ground), which provides more adaptability for the machine. The front wheel auxiliary drive adopts PLC interlocked with rear wheel gear.
Steering system:
The Single cylinder, front axle with large steering angle, and load sensing fully hydraulic steering system can realize the prior operation of the front wheel steering, and assist the frame to steer articulated, which can ensure smaller turning radius and the flexibility.
Operation system:
The comfortable operation system adopts excellent diamond cab, air-conditioning, defrosting and exchanging the air automatically. The system takes ABS adjustable operation panel and adjustable damping seat. The imported instruments and operation levers and ergonomic instrument distribution ensure the comfortable and convenient operation.
Working device:
The blade adopts the adjustable large runner and double slide track setup of Xugong solely owned. The working blade adopts the wear-Resistant materials of high strengthen, and the single cylinder can control the switch of the digging angle and adjust it flexibly according to the hardness of the soil. 
Safety system:
The hydraulic double-circuit travel brake, emergency parking device, hand brake; the brake valve is integrated with the  prefill valve, and the four rear wheels take the hydraulic shoe brake. The braking system adopts the drum brake which is safe and reliable.
