Motor Grader

719H Road Motor Grader

‌•Rated power：190HP (142kw/2200rpm)

‌•Operating weight：15600kg

The 719H motor grader is a robust and versatile road construction machine designed for high-performance earthmoving tasks. Built with a heavy-duty steel chassis, it integrates a powerful engine and advanced hydraulic systems to ensure exceptional traction and operational stability. Equipped with a multifunctional blade capable of both horizontal rotation and vertical adjustment, the machine achieves precise control over slope gradients and surface contours. Key applications include roadbed preparation, slope shaping, ditch excavation, and material distribution, seamlessly combining grading, leveling, and compaction in a single workflow. Ideal for large-scale infrastructure projects such as highway construction, urban road upgrades, airport runway maintenance, and agricultural water management, the 719H significantly enhances productivity, operating at speeds over 20 times faster than traditional manual methods while maintaining superior precision.
