Motor graders are the machines that are utilized in various construction sites. Before that, the motor grader was only used for road construction, leveling, and surfacing purposes. However, if we analyze today’s construction sites we can see the motor grader in multiple jobs. There is a slight difference between the variants of motor graders but modern are more useable and can perform multiple tasks. Tough advancement and infrastructure projects are increasing in regions, especially in North America, where contractors prefer motor graders for their activities. Modern motor graders are usually used to smooth wide and leveled surfaces.
This motor grader is utilized not only to level the surfaces but also to redevelop and maintain the road in a more efficient way. In America, the machine is also highly beneficial and utilized for snow removal purposes, since for the past few years, the weather of the region has dramatically changed and seen the heavy snowfall. This equipment can help in the removal of snow and earth-moving tasks according to needs.
Motor grader comes with a variety of features and new additions, which them the most significant is its adjustable blade. The blade is the primary and most important part of the motor grader. The blade can be used for cutting, spreading, and leveling tasks on a variety of terrains and is often positioned between the front and back axles. Some motor graders have a scarify feature that allows the operators to scarify a layer and then use the blade to remove it. After that, another new coating is applied, and the top layer is scarified once again to secure it.
Modern Motor Graders
The current equipment market has seen a different and versatile range of motor graders, with many models classified and based on the structure of the frame. Also, there are companies that manufacture motor graders in different sizes. Earlier, we could only see the standard size of the motor grader that was used in heavy earthmoving activities. Now the transformation changes the way of its manufacturing and operators experience the compact motor grades. They are ideal for narrow and urban construction activities.
Motor Graders are classified into different categories based on their frame arrangements and other aspects, the most prominent classification of motor graders is into two categories.
Rigid Frame motor grader
If you were in the 1980s or 90s operating the traditional motor grader, particularly rigid frame motor grader it could be challenging for you to work effectively. The changes and transformations in machines in the past few decades are remarkable, it’s changed the way of working on and off-site.
Rigid motor grader usually has only one axle and are only capable of moving either left side or right on the basis of their axle. This version of the traditional motor grader was popular for performing earthmoving activities in a limited frame.
Dual Axle Motor Grader
Dual axle motor grader also know as the Articulated frame motor graders. This version of the equipment is a little bit more advanced and more usable than the rigid frame motor grader due to its front and rear axle. This variant usually has both a front and rear axle. The blade is usually located somewhere between the two axles.
The articulated frame graders are usually used in urban spaces and where the construction site is narrow and tight spaces. Currently, most contractors are using articulated frame motor graders because of their functions and the increasing demand for urban projects.
There are essentially two categories of articulated motor graders depending on the joints. A front-mounted articulation joint and a rear-mounted articulation joint are both included. A sharper view of the moldboard is made possible by the grader with the articulating joint behind the cabs.
Four-wheel Operating System For Uneven Surfaces
The other element that distinguishes the different categories of motor graders is the system of functioning, which solely depends on the wheel drive. Most operators used to work with a four-wheel drive system, and some others prefer the front wheel drive. It also depends on the condition of the site and workload. For uneven and hard surfaces where mostly unpaved roads, the all-wheel system is better while it is redundant for smooth clear areas.
Compact And Large Motor Grader
For most tasks, a compact motor grader with 80–150 horsepower is suitable. Road maintenance, landscaping, and other tasks requiring precise spacing are ideal for compact graders.
For comparatively larger roads, such as state and national highways, larger motor graders may perform the same tasks on a much greater scale. Smaller machines are hydrostatically propelled, however larger machines are known to use a torque converter drive or direct drive transmission system.
Conclusion
There have been a lot of changes and transformations in traditional and modern graders. In terms of many things from its power, and effectiveness to productivity a lot of components have been updated. Currently, operators are comfortability operating heavy equipment and provide maximum work effortlessly. Also, compact motor graders revolutionize the grading process in urban areas. It is now capable of meeting the demanding needs of modern construction projects.
