Key Features and Applications
Cummins Engine with Variable Power Control
The grader is powered by a Cummins QSL8.9 diesel engine producing 280 horsepower (220 kW at 2,100 rpm). Featuring variable power control technology, the power plant adapts torque output dynamically to match shifting work loads, conserving fuel during transit and light spreading while providing strong drawbar force during heavy subgrade cuts.
Load-Sensing Hydraulic System
The hydraulic architecture employs load-sensing technology that distributes flow and pressure in direct response to operational resistance. This reduces lever operating forces, delivers sensitive and predictable control response, and allows smooth compound cylinder movements during simultaneous blade lifting, side-shifting, and steering.
Intelligent Temperature-Controlled Cooling Fan
Equipped with an intelligent fan control system, the cooling fan dynamically adjusts rotational speed according to real-time temperature monitoring of engine coolant and hydraulic oil. This reduces parasitic power loss, cuts cooling system noise, and maintains stable thermal efficiency in tough operational environments.
Electronic Double-Handle Control Ergonomics
The operator cab utilizes electronic double-handle control technology, integrating blade cylinder adjustments, steering, and machine travel controls into intuitive dual joysticks. This consolidated layout reduces operator physical effort, streamlines multi-function maneuvering, and improves work cycle efficiency.
Wet Brake Axle and High-Strength Steel Construction
The machine incorporates a heavy-duty wet-type brake drive axle, delivering dependable braking torque, continuous thermal dissipation, and long service life. The entire chassis and structural assemblies are fabricated from high-strength steel, engineered specifically for high-load operations including open-pit mining, heavy bulldozing, and haul road maintenance.
