|The motor grader is the main machine used in the earthwork for shaping and leveling operations, and is widely used in large-scale ground leveling operations such as roads and airports. The reason why the motor grader has a wide range of auxiliary work is because its moldboard can complete 6 degrees of movement in space. They can be carried out either singly or in combination. The motor grader provides sufficient strength and stability to the subgrade during subgrade construction. Its main methods in roadbed construction include leveling operations, brushing operations, and filling embankments. The motor grader is a high-speed, high-efficiency, high-precision and multi-purpose earthmoving machine. It can complete the ground leveling and trenching, scraping, bulldozing, snow removal, loosening, compaction, fabric, mixing, assisting and land reclamation of important areas such as important content fields and farmland. It is an important equipment in the construction of national defense engineering, mine construction, road construction, water conservancy construction and farmland improvement. Highway subgrade is the foundation of pavement and an important part of highway engineering. The roadbed is subjected to traffic loads 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, highway subgrades generally take the form of embankments and roads.|
The original motor grader can be traced back to the United States at the end of the 19th century. Since the 1920s, in the past 80 years of development, motor graders have experienced low speed to high speed, small to large, mechanical control to hydraulic control, mechanical shift to power shift, mechanical steering to hydraulic power steering and then Full hydraulic steering and the development of a complete rack to shovel rack. The reliability, durability, safety and comfort of the whole machine have been greatly improved. With the development of technology, the development and application of mechanical manufacturing and hydraulic technology. As a result of their combined application in engineering machinery products, high technology represented by modern microelectronics technology is increasingly used to transform the traditional structure of engineering machinery products. The transplantation application of mature technology has greatly promoted the further improvement of the comprehensive technical level of the grader. Motor graders have developed to the level of self-leveling. Automation has become a trend in graders. Therefore, the grader has also been widely used.
