Motor Grader

Motor Grader Graders are the necessary construction machinery in the construction of national defense project, mining construction, urban and rural road, and water conservancy construction and farmland reconstruction. A grader, also commonly referred to as a road grader, a blade, a maintainer or a motor grader, is an engineering vehicle with a large blade used to create a flat surface. Typical models have three axles, with the engine and cab situated above the rear axles at one end of the vehicle and a third axle at the front end of the vehicle, with the blade in between. Motor graders history is fairly well documented, beginning with horse-drawn equipment that first appeared in the 1870s. Then there is a class of motor graders significantly with smaller size are be used for specialty work in confined work spaces, often as multi-purpose tool carrier with a variety of attachments and often using hydrostatic drives geared drive trains. More even that motor graders are used extensively for snow removal, especially in northern rural areas. In civil engineering, the grader s purpose is to "finish grade" (refine, set precisely) the "rough grading" performed by heavy equipment or engineering vehicles such as scrapers and bulldozers. Graders can produce inclined surfaces and surfaces with cambered cross-sections for roads. In some countries they are used to produce drainage ditches with shallow V-shaped cross-sections on either side of highways. Graders are commonly used in the construction and maintenance of dirt roads and gravel roads. In the construction of paved roads they are used to prepare the base course to create a wide flat surface for the asphalt to be placed on. Graders are also used to set native soil foundation pads to finish grade prior to the construction of large buildings. And our GR series of grader are mainly used in large area ground leveling such as road, airport and farmland and the operation of ditching, slope scraping, bulldozing, scarifying and snow-removing.
