  1. Grader

    A grader, also commonly referred to as a road grader, a blade, a maintainer, or a motor grader, is a construction machine with a long 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. In certain countries, for example in Finland, almost every grader is equipped with a second blade that is placed in front of the front axle. Some construction personnel refer to the entire machine as "the blade." Capacities range from a blade width of 2.50 to 7.30 m and engines from 93–373 kW. Certain graders can operate multiple attachments, or be used for separate tasks like underground mining. In civil engineering, the grader's purpose is to "finish grade" the "rough grading" performed by heavy equipment or engineering vehicles such as scrapers and bulldozers. 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.Graders can produce inclined surfaces, to give cant to roads. In some countries they are used to produce drainage ditches with shallow V-shaped cross-sections on either side of highways.
