Introduction and application of grader
Grader is the main machine used for shaping and leveling operations in earthwork. It is widely used in highway, airport and other large ground leveling operations. Grader has a wide range of auxiliary operation ability, because its scraper board can complete 6 degrees movement in space.
Highway subgrade is the foundation of road surface, and it is an important part of highway engineering. The subgrade bears the traffic load from the road surface, which is the supporting structure of the road. It must have enough strength, stability and durability. According to the topography, highway embankment generally adopts two forms of embankment and cutting.
They can be carried out individually or in combination. Grader can provide sufficient strength and stability for Subgrade during subgrade construction. Its main methods in subgrade construction include plain operation, brushing slope operation and filling embankment.Grader is a high speed, high efficiency, high precision and multi-purpose earthwork construction machinery. It can accomplish large area ground leveling, trenching, slope scraping, earth pushing, snow removing, loosening, compaction, cloth distribution, mixing, installation and reclamation. It is an important equipment in the construction of national defense engineering, mine construction, road construction, water conservancy construction and farmland improvement.
