Introduction and main applications of graders

Graders are the main machines used for shaping and leveling operations in earthwork projects. They are widely used in large-scale ground leveling operations such as highways and airports. The reason why graders have a wide range of auxiliary operation capabilities is that their scraper blades can complete 6-degree movement in space. They can be carried out alone or in combination. In roadbed construction, graders can provide sufficient strength and stability for the roadbed. Its main methods in roadbed construction include leveling operations, slope brushing operations, and embankment filling. Graders are high-speed, efficient, high-precision and multi-purpose earthwork machinery. It can complete large-scale ground leveling and trenching, slope scraping, bulldozing, snow removal, loosening, compacting, spreading, mixing, auxiliary loading and land reclamation in important highway fields, farmlands, etc. It is an important equipment in the construction of national defense projects, mining construction, road construction, water conservancy construction and farmland improvement. Highway roadbed is the foundation of the road surface and an important part of highway engineering. The roadbed bears the traffic load from the road surface and is the supporting structure of the road surface. It must have sufficient strength, stability and durability. Depending on the terrain, the roadbed of a highway generally takes the form of embankment and cutting.
