A motor grader is a large piece of machinery used in earthwork projects, primarily for tasks such as ground leveling, slope grading, trenching, and spreading mixed materials.

HHH Cooperation MACH. ELEC.CO., LTD. offers front-wheel assist systems, working systems, and braking systems.

Front-wheel auxiliary drive hydraulic system: The motor grader’s front-wheel assist drive system features a load-sensing design, powered by an S45 open-type pump, PVG valves, and a radial piston Black Bruin unit—collectively forming the front-drive assistance system. The load-sensing signal is precisely regulated by proportional valves, allowing users to adjust the system pressure according to varying ground conditions. This flexibility ensures that the traction force delivered to the front wheels remains fully customizable. By incorporating this front-wheel assist drive, the machine’s overall traction capability is enhanced by up to 30%, while simultaneously improving the efficiency and quality of grading operations.
