722H Motor Grader


Features


Motor Grader 722H
1. Our 722H motor grader adopts ShangChai engine with model SC11CB220G2B1.
2. The adopted hydraulic system can achieve efficient control over every working part.
3. The 6 forward and 3 reverse power-shift transmission features sing-handle and electro-hydraulic control, and ensures simple and convenient operation.
4. It is available with the hydraulic lock and auto lock/unlock NO-SPIN differential, providing stability and powerful traction.
5. Designed with perfect axel load allocation, the motor grader is applicable to hard surface cutting with excellent stability.
6. When combined with box-typed frame, the transmission system allows the vehicle to complete heavy-duty work.
7. The machinery is equipped with flexible blade suspension system and articulated frame, making it enjoy a wide working range.
