Motor Grader PY220H

Description of Motor Grader:
The purpose of the motor graders is to refine, set precisely the rough surface. In some occasions, motor graders can produce inclined surfaces and surfaces with cambered cross-sections for roads.
Features of Motor Grader PY220H:
1. Equipped with SDEC C6121 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 PY220H:
Motor grader is a kind of engineering vehicle/construction equipment (construction machinery), motor grader_ PY220H is used to create flat surface in the airport or construction of paved road. And motor graders are also used to produce drainage ditches with shallow V-shaped cross-sections on either side of highways.
