Motor Grader Applications and Maintenance Guidelines

Motor grader plays an important role in leveling and grading work in earth moving and foundation. It is widely used in large-scaled ground surface leveling, such as, highway and airport construction. The grader is a great tool to assist other machines complete working, it can be used alone or combined with other machines. In the road building, the grader is indispensable, especially in the finishing stage, where the grader will spread and flatten the soil to create a well smooth, wide-ranging and level surface, making a strong and stable foundation for the road construction.


Motor grader is a kind of earth moving and foundation machine with high speed, high efficiency, high accuracy and multiple functions. It can be used in road leveling, trenching, slope cutting, bulldozing, snow removal, earth scattering and mixing, land clearing and so on. It is an important part in mineral construction, road repairing, water conservancy and farmland improvement. The road bed is the foundation of the road surface, an important part in road construction, it bears the traffic loads, so the road bed must have high strength, stability and durability, which is the daily work of the grader, simple but tough.

Hydraulic oil is one of the most important factors that need to be maintained well in the motor grader daily maintenance. The hydraulic oil is not only the transmission medium but also the lubricant, which is used to seal the parts, and the hydraulic oil bears the role of heat dissipation as well, therefore, it is very important to keep the hydraulic oil efficient and reliable. Qualified hydraulic oil features proper viscosity, anti-rust, antioxidant and low volatility. The hydraulic oil should be kept clean and avoid pollution, thus providing the machine the most purified power source.
