Desc ription of Motor Grader:
A motor grader, also called a road grader, a blade, a maintainer, is an engineering vehicle or construction equipment(construction machinery) with a large front dozer used to create a flat surface.
Features of Motor Grader-PY190H:
1. Equipped with reliable SDEC C6121 engine or genuine Cummins engine
2. Sing-handle electro-hydraulic controlled power-shift T/M, 6 forward & 3 reverse shifts makes operation easy and convenient
3. Hydraulic lock, auto lock/unlock NO-SPIN differential ensures stability and powerful traction
4. Ideal axel load allocation provides excellent stability while cutting hard surface
5. Serviceable, efficient hydraulic system enables every part to be fully used
6. Box-typed frame and advanced T/M enable it to complete heavy-duty work
7. A wide working range is accomplished through flexible blade suspension system and articulated frame
Applications of Motor Grader-PY190:
Motor grader PY190H is used to create flat surface in the airport or construction of paved road.
It is a ideal engineering vehicle/construction equipment (construction machinery), also can be used on ranches, large farms and plantations.
