Easy maintenance

With 6 forward gears and 3 reverse gears, the electro-hydraulically controlled power shift transmission can select the optimal gear based on the working road condition to realize the best match between traveling and operation. The integral three-segment drive axle is built internally with imported no-spin automatic limited slip differential to guarantee stable and reliable drive. The balance box is capable of 15° angular swing in vertical direction and the heavy-duty roller chain drive guarantees better terrain adaptability of the machine. It can meet the normal operations under special road conditions, featuring stable power output and strong drive force.

Operational performance

It features the highest traction force among the domestic motor graders of like type and the highest operating efficiency among the domestic products of like type. 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. With high resistance against external force impact, the link type swing frame is applicable for the working conditions with high operating volume and severe operating environment.
