Get to Know Important Components of a Motor Grader
United Tractors, Jakarta – In the road construction projects, we frequently see the use of heavy soil compaction equipment, such as motor graders. The widespread use of motor graders raises the question: What exactly is a motor grader? Is there anything unique about this heavy equipment?
A motor grader is a type of heavy machinery that is equipped with a long blade and is commonly used to level land surfaces. There are six wheels on a motor grader’s drive system: four wheels on the back that used to keep the grader balanced and mobile, and two wheels on the front are used for dredging and are located directly in front of the blade or long knife.
The motor grader’s six giant wheels make it perfectly maneuverable, allowing it to perform its functions properly. The motor grader has several functions, including leveling and shaping the land, helping the road finishing process, ditching, mixing soil and construction materials, digging channels, and forming sloping surfaces.
Whether the required job mobility is high or low, the motor grader can certainly perform the previously mentioned functions if it features complete and prime components. So, what are the components of a motor grader? Here’s a detailed review.
- Front Blade
The front blade is the first component ensuring a high-precision road surface forms a motor grader reliability. This part is essential for leveling soil and cutting materials. The size and running weight of the motor grader will determine the size of the blade. - Front Pull Hook
This part, as its name implies, is used to pull materials. It is located at the front of the motor grader, just like the front blade. On motor graders, we often find two kinds of front pull hooks: a U-shaped bracket welded on the front axle and a front weight with nails. Both function as features for pulling materials. - Push Plate
Next, there is a push plate, which is a part of a motor grader that can be used to cut down or push trees that are stuck in mud. Furthermore, on extremely difficult terrain, the Komatsu motor grader and other brands use the push plate as a weight or counterweight to keep the front wheels from lifting. - Moldboard
Moldboard is a component of the motor grader that is used to shift the blade to the right or left using hydraulic control. When the motor grader is operating, this moldboard can maintain the blade movement so it stays steady.
The moldboard usually has two double action single rod cylinders on the left and right, as well as a single tilt cylinder, so it can operate properly.
Well-known Japanese motor graders like Komatsu have enough components to enable the building process to get more effective. A good blade linkage position is one of the Komatsu motor grader’s features, so that the front tires and moldboard are obviously visible without any obstruction. - Cabin
As we all know, the cabin is a control room where the operator can operate the motor grader. In this cabin, the operator can move and control the lever as needed to achieve the best results. The Komatsu motor grader’s cabin is designed ergonomically to ensure the operator is always comfortable while operating the machine. Even if the operator has to work in harsh conditions, they can be more productive and provide maximum work results when they are in maximum comfort. - Circle
The circle component controls the direction of the rotating blade based on the construction’s needs. In general, this circle feature has a hydraulic motor that controls the movement of the blade. The power from this hydraulic motor moves the blade by going through the level in the operator’s cabin. The circle is an important part of a motor grader, just like the other parts. If this circle gets damaged, it can slow down general construction work. - Scarifier
The scarifier is a part of the motor grader that digs through hard materials like ice, asphalt, and other things that are hard for other parts of the motor grader to dig through. The scarifier is equipped with a variety of teeth that can adjust the workload. More teeth will be used on the scarifier if the material that needs to be dug up is harder. - Ripper
The ripper is a part of a motor grader that is often used to dig up rocks. Additionally to rocks, the ripper can also dig up other hard things that the scarifier can’t break up. These two parts are linked to each other. If the scarifier is unable to excavate the material, the ripper will take over the digging. - Extension Blade
As the name implies, this extension blade is an additional blade, which means it can connect the blade to the motor grader, making it longer on both the right and left sides. With the extension blade, it’s easier to do tasks like leveling the ground. Although its function can increase work productivity, using this extension blade for heavy work is not recommended because if the workload is too heavy, the work results will be less than optimal. - Hydraulic Blade Tip Control
The last component is the hydraulic blade tip control, which is a motor grader component that uses the hydraulic system to adjust the blade’s cutting angle. The operator in the motor grader cabin will make adjustments that are required to get the right cutting angle. This is where the operator’s abilities will be tested, as the operator must be able to find a precise cutting angle.
Here are a few explanations of the components of a motor grader and their functions. Motor graders, like other heavy equipment, have the main function of increasing productivity in construction work.
However, motor graders aren’t always used in building projects because their main job is to level or spread materials when roads are being built or maintained. But it is easier to build roads and gets better results when motor graders with advanced components are used.
