PY190H Motor Grader

PY190H type grader is by PY190C - 5 to develop export-oriented type, whether performance, work efficiency and operating comfort and appearance are much better than the domestic similar type. The transmission system, hydraulic system, braking system mainly use the imported parts, high reliability, with import grader all functions, and original type parts has quite high interchangeability, but its price performance ratio higher, with domestic manufacturers have any similar type of competition advantage.
Being a kind of multi-purpose shovel transport machinery, mainly for the earth engineering site plastic in peace operations, can also be used to digging channel, slope scraping, bulldozing, snow removal, ripping, mix stabilized soil or other road materials, road construction is an indispensable equipment.
