    Main Features
    PY190H Motor Grader

    Equipped with a Komatsu-technology drive axle and a fully floating rear axle structure that enhances wheel installation stability and load distribution. This design reduces tire slippage and wear, improving traction and durability on rough terrain.

    PY190H Motor Grader

    The flexible blade suspension system and articulated frame expand the working range, allowing for more efficient and precise grading.

    PY190H Motor Grader

    The hydraulic system uses a single-pump oil supply configuration. Oil is distributed through a diverter valve to the left and right control valves, with local circuits reconverging afterward. This setup ensures a stable system pressure of 17.5 MPa while keeping overall flow low and minimizing energy loss, maintaining performance without compromising efficiency.

    PY190H Motor Grader

    Equipped with heavy-duty dual-row roller chains built with an average breaking strength of 26 tons. This design eliminates the need for regular tension adjustments and easily handles the demands of harsh working conditions, effectively preventing chain breakage during high-load operations.

    PY190H Motor Grader

    The blade/moldboard delivers a cutting depth of up to 535 mm and features a wide curvature adjustment range from 29° to 77°, making it highly efficient at turning over different types of soil. This allows for more professional and precise grading across various job sites.

    PY190H Motor Grader

    The operator benefits from an unobstructed panoramic view and a suspended seat with headrest for added comfort. The cab can be optionally equipped with ROPS/FOPS for improved safety and features a comfortable interior with MP3/FM radio, high-power air conditioning (cooling and heating), and a USB charging port.

    Front-wheel assist and full-wheel drive refer to the same feature, hydraulic motors are installed on the front wheels to provide additional traction. Standard models without this feature are typically rear-wheel drive.

    Selecting a suitable motor grader for road construction involves evaluating several key factors. Start by understanding the scope and scale of your project, including terrain type and soil conditions. Choose a grader with the appropriate size and capacity to match your needs, and make sure the blade specifications align with the required tasks. Consider operator comfort and control, engine power, and hydraulic performance, particularly smooth and precise blade movement. Fuel efficiency also matters, helping you achieve optimal performance at a lower cost. Additionally, assess the grader's compatibility with the expected working cycles and the availability of after-sales support and maintenance. Ground conditions will also influence your choice, especially when working on challenging surfaces or varying elevations.

    To determine whether a motor grader matches the soil and terrain conditions in your region, you need to consider both the environment and the specific features of the grader. Compact models or those designed for maintenance work are ideal for grading tasks in narrow spaces, such as ditches, utility areas, or urban zones. Heavier-duty graders, on the other hand, perform better on rough or rocky surfaces. For soft, muddy, or wet ground, it’s best to choose a model equipped with features like larger tires or enhanced traction systems. These can improve stability and efficiency under difficult working conditions. Matching the motor grader’s capabilities with the local terrain ensures optimal performance and fewer delays on site.

    Yes, motor graders are highly versatile and can be used in a wide range of applications beyond standard road leveling. They’re effective in earthmoving projects, slope formation, spreading and loosening materials, trenching, ditching, and even snow and ice removal. Our motor graders are also suitable for:

    • Site preparation and fine leveling, clearing debris and ensuring a smooth surface before construction
    • Breaking up old pavement or hard soil, especially when equipped with a rear ripper
    • Shaping and trimming slopes for landscaping or terrain modification
    • Mixing, spreading, and compacting base layers during road construction
    • Pushing tasks, when fitted with a front blade, and maintaining balance with front and rear counterweights

    Motor graders play a key role in maintaining safe and functional urban roads. They help create smooth and even surfaces, ensure proper drainage, and support road safety by eliminating bumps and irregularities. These machines contribute to a more comfortable driving experience for city traffic. As grading technology continues to evolve, motor graders have become more precise, efficient, and environmentally friendly. Their versatility and reliability make them essential for both road construction and long-term maintenance, especially in cities where infrastructure development requires consistent quality and performance.
