What is the earth-moving machinery used by graders to level the ground with scrapers? The scraper is installed between the front and rear axle of the machine and can be lifted, tilted, rotated and extended. Flexible and accurate, easy to operate, high site leveling accuracy. It is suitable for subgrade and pavement construction, slope construction, side ditch excavation, pavement mixture mixing, snow sweeping, material pushing, dirt road maintenance and gravel road maintenance. Grader Application Grader is the main machinery used for shaping and leveling in earthwork, which is widely used in expressway, airports and other large-scale ground leveling operations. The reason why the grader has extensive auxiliary operation ability is that its scraper can complete 6-degree motion in space. They can be carried out individually or in combination. Grader can provide sufficient strength and stability for subgrade construction. Its main methods in subgrade construction include leveling operation, slope brushing operation and embankment filling. Grader is a kind of high-speed, high-efficiency, high-precision and multi-purpose earth-moving machinery. It can complete large-scale ground leveling, ditching, slope scraping, earth pushing, snow removal, soil loosening, compaction, cloth distribution, mixing, loading assistance and land reclamation for roads and farmland. It is an important equipment in 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. Subgrade bears the traffic load from the pavement and is the supporting structure of the pavement. It must have sufficient strength, stability and durability. According to the different topography, embankment and cutting are generally used for highway subgrade. The characteristics of graders The original graders can be traced back to the United States at the end of 19. Since the 1920s, in the development process of nearly 80 years, graders have experienced the development process from low speed to high speed, from small to large, from mechanical control to hydraulic control, from mechanical shift to power shift, from mechanical steering to hydraulic power steering to full hydraulic steering, and from full hydraulic frame to shovel frame. The reliability, durability, safety and comfort of the whole machine have been greatly improved. Today, with the development of high technology, the development and application of machinery manufacturing and hydraulic technology. With their combined application in construction machinery products, high-tech represented by modern microelectronics technology is more and more widely used to transform the traditional structure of construction machinery products. The transplantation and application of mature technology has greatly promoted the further improvement of the comprehensive technical level of grader. The grader has developed to the level of automatic leveling. Automation has become the development trend of grader. Therefore, graders are also widely used. In particular, the M-series motor grader introduced by Caterpillar has completely changed the integration of the machine control system on the operating handle similar to the joystick of an airplane, so that the operator can finish the construction task more intelligently.
