Motor Grader
A motor grader is a construction machine that uses a long blade to create a flat surface. Typical road grader has three axles. The engine and the cab of the grader are situated above the rear axles at one end of the machine. A third axle is equipped at the front end of the vehicle and the blade is situated in between. A motor grader is usually used for constructing and maintaining dirt roads and gravel roads. In paved road constructions, it could be used for preparing the base course by creating a wide flat surface where the asphalt can be placed on. A motor grader could also set soil foundation pads before the construction of large buildings.
Our GR215C motor grader is ideal construction machinery for the construction of national defense projects, mining construction, urban and rural road, water conservancy construction and farmland reconstruction.
Characteristics
