PY190H Motor Grader
This 190 HP motor grader delivers strong traction and increased blade capacity, making it suitable for demanding earthmoving tasks. Its configuration ensures consistent performance across large-scale applications, even in challenging ground conditions.
- Length 8950 mm
- Operating weight 15600 kg
- Blade length 4268 mm
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.
The flexible blade suspension system and articulated frame expand the working range, allowing for more efficient and precise grading.
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.
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.
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.
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.
