Motor Grader

 

Motor Graders are very versatile pieces of equipment that help build roads and parking lots.  In the hands of a skilled and knowledgeable Operator they have the ability to build drainage ditches, slopes and can even clean-up a vertical high-wall!  They come in a wide variety of sizes that range from the size of the average automobile to being more than 45 feet in length, up to 24 feet wide with more than 500 horse power, and weighing in at over 60 tons!

Description

A grader, also commonly referred to as a road grader or a motor grader, is a construction machine with a long blade used to create a flat surface during the grading process. 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.  Some construction personnel refer to the entire machine as a “blade”, or perhaps a “maintainer”.

Graders are used in the construction and maintenance of dirt and gravel roads. In the construction of paved roads they are used to prepare the base course to create a wide flat surface upon which to place the pavement material. Graders are also used to set soil foundation pads to “finish grade” prior to the construction of large buildings. Graders can produce inclined surfaces, to give cross-slope to roads. They are also used to produce drainage ditches with shallow V-shaped cross-sections on either side of highways.
