The core value of a motor grader lies in its finishing capabilities. Our graders feature an advanced, load-sensing hydraulic system that provides operators with smooth, millimeter-perfect control over the center moldboard. The blade can be easily pitched, tilted, and side-shifted under heavy loads, ensuring precise cutting angles for crowning roads, cutting ditches, and creating perfectly leveled foundations for asphalt paving.
Maintaining road surfaces often involves operating on loose, uneven, or sloped terrain. This motor grader utilizes an articulated frame design, allowing the front and rear axles to track differently (crab steering) to resist side draft when moving heavy windrows. Coupled with a heavy-duty rear tandem drive, the machine delivers unwavering pushing power and exceptional stability, significantly boosting operational efficiency on rugged mining haul roads.
Definition: A motor grader (or road grader) is a heavy earthmoving machine equipped with a long, adjustable blade (moldboard) between the front and rear axles. It is primarily used for fine grading, leveling dirt or gravel, creating flat foundations before asphalt paving, ditching, and maintaining unpaved mining haul roads.
Function: Bulldozers are designed for rough grading—pushing massive amounts of dirt and rocks forward. Motor graders are designed for fine grading—leveling the surface to exact millimeter tolerances.
Tool: Bulldozers use a heavy front-mounted blade; graders use a highly maneuverable center-mounted moldboard.
Application: Dozers clear the land; graders finish the road.
The articulated frame features a central hinge joint that allows the machine to bend in the middle. This enables "crab steering," where the rear tandem-drive tires stay on firm ground while the front tires and blade operate on a soft slope or in a ditch, enhancing stability and turning radius.
