The motor grader is a large multipurpose machine used for many different construction operations. These many operations include but are not limited to: grading, shaping, bank sloping, ditching, and scarifying. Graders can also be employed to clear roads of snow and debris without doing any damage to the underlying roadway surface. Graders are much more “gentle” than dozers and other large pushing machinery. Motor graders are designed for preparing the substrate of roads and other flat earth as well as leveling aggregate. By using the blade skillfully, it is also possible for the contractor to use motor graders to finish a slope and dig a ditch. 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. Motor graders are commonly used in the construction of dirt roads, paved roads and gravel roads. The motor grader can also be used by the contractor in the maintenance of these road types and ditches as well. 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. The amount of material that can be pushed by a motor grader is much less than what a dozer can push. This is because motor graders are built for fine tuning surfaces rather than just pushing materials in a bulk amount. Contractors generally estimate grader production on either an area basis or linear basis completed per hour.
Motor Grader Production Calculations
The motor grader is used in a variety of application in a variety of industries. Therefore, there are many ways to measure its operating capacity, or production. One method expresses a motor grader’s production in relation to the area covered by the moldboard.
