What is a grader?
A motor grader most commonly referred to as a motor grader or a road grader is a multipurpose earth moving machine that is used not only on construction sites to create a flatter smoother surface in road construction projects, but also in the mining/quarrying industry to Mining under the surface. They have a unique structure, the main feature is a long, large and adjustable blade between the front and rear double wheels.
Due to the multiple uses of this equipment and its precision in producing a high quality surface finish in the shortest possible time, the rate of demand for motor graders has increased significantly over the past few years and is therefore considered an absolutely essential piece of equipment in any construction construction site.
What can you do with a motor grader?
Motor graders are primarily used in various activities in the following fields: fine leveling in civil engineering projects, in the mining industry, in foundation works for large structures, in paving and earthworks, and in snow removal.
Motor graders were originally used to build unpaved roads, such as dirt and gravel roads, to level the underlying terrain, resulting in a flat and smooth surface, and to carry small amounts of material from one place to another. To date, motor graders are still used in rural areas for small-volume dirt road construction.
Second, they are used during the construction or maintenance of paved roads to prepare the uppermost layer by creating a flat surface on which to lay asphalt.
Third, the motor grader ensures efficient use of the roller/compactor with minimal loads. Additionally, motor graders are used in snowy areas to remove snow and debris before moving them from one place to another.
They are also used in the foundation works of a project to set the natural soil to the required level before building large buildings. Therefore, graders can be used to mix two or more materials on any construction site.
A motor grader with a scarifier is capable of removing the top layer of previously destroyed pavement damaged by heavy traffic, then spreading/resurfacing the pavement with a new layer of gravel, aggregate, or asphalt, and polishing it.
Finally, on mining sites, motor graders can be equipped with multiple attachments or designed to perform specialized mining tasks.
How are motor graders maintained?
Proper maintenance is important for your motor grader to continue to operate efficiently and perform at its peak performance.
Most importantly, the motor grader blades mounted to the moldboard must have a good sharp cutting edge. This increases the ease with which the blade cuts through the material. How worn the material is ultimately determines how quickly the blade wears. Once the blades are worn, they should be replaced as soon as possible to avoid the risk of the moldboard also wearing out, resulting in unnecessary replacements and thus increased costs.
In addition, the air filter of the grader should be checked from time to time to ensure that no dust has accumulated in it. The presence of dirt can clog the air filter, reducing the efficiency of the classifier and subsequently increasing fuel consumption. Therefore, they require constant monitoring by the operator or the introduction of a pre-filter, which acts to reduce the amount of dirt particles entering the air filter. Using a pre-filter helps reduce the number of times the operator has to change the air filter, saving money that would otherwise be incurred.
The teeth of the ripper or ripper should be monitored so that they do not wear to the point where the ripper handle reaches. If this happens, the ripper and ripper handle must be replaced, a more expensive task than just replacing the ripper teeth.
Tire pressure is another essential element that must be checked and monitored regularly, as tire traction can affect grade accuracy on your motor grader. Therefore, the tire threads should meet the required specifications in order to provide sufficient ground grip and prevent the machine from skidding.
For the overall comfort and safety of the operator, floor mats, brakes, seat belts, steering wheel and handles should be inspected regularly. The presence of loose handles, seat belts can make work more tedious and difficult to perform, resulting in lack of precision and longer working hours, reducing overall productivity.
