A
motor grader is a huge productive earth-moving apparatus which is used
to level a surface. It is used for the leveling of roads and
construction sites. The motor grader, apart from hauling road
construction, is also responsible for the maintenance and soft grading
of cell floor liners.
On the basis of strength and the types of grades used in the motors,
motor graders are classified as :
- Cat motor graders
- Brush less motor graders
- Rotor nut motor graders
Mechanical Operations
In design and applications motor grader differs from a simple grader.
Motor grader functions on all the four wheels and can be operated from
the center of the machine. At the ends it has a plow which stays close
to the ground. It also has a different type of arm which can be used to
pick up materials and move them to other places.
Motor grader also has a blade which is situated under the cab to spread
and push gravel. It has hydraulic controls that provide smooth,
predictable response when the lever is moved. Motor graders are very
useful while working on a project which requires dirt holes to be
filled.
Applications
Motor graders finds its application in the following areas :
- Motor graders are used for the maintenance of public roads.
- They are also used in construction sites.
- In land filling applications motor graders has greater utility.
- They also find their applications in vacuum casting, forming and
weldings.
