The engine model is SC9DF220G4 with a rated power of 162kW and meets the National IV emission standard. The gearbox is from Hangzhou Gear, with 6 forward gears and 3 reverse gears. The maximum traction force (f=0.8) is ≥93kN, the maximum forward speed is 40km/h, and the maximum reverse speed is 25km/h.

Power System

It adopts a Shangchai engine, meets the National IV emission standard, and is equipped with an ECO mode for energy conservation and environmental protection. Its rated power reaches 162kW, providing strong power for the grader and ensuring efficient operation under various working conditions.

Hydraulic System

It adopts a hydraulic system with load sensing, proportional priority, and pressure compensation, equipped with a variable displacement piston pump and working valves. It can realize power distribution on demand, reduce energy loss and heat generation in the hydraulic system, and support multiple compound actions simultaneously to improve construction efficiency.

Blade Parameters

The blade length is available in options such as 3.7m, 4.0m, and 4.3m. It is standard equipped with a blade floating function, which can reduce work difficulty and the operator’s work intensity, effectively improving construction efficiency.

Structural Design

The frame adopts a flanged box-type structure, and the front frame is a continuous upper and lower plate structure, which has high strength after CAE global optimization. The traction frame is an A-shaped structure composed of two square steels, with good durability. The Caterpillar self-made rear axle is equipped with a final drive with four planetary gears, having strong load-bearing capacity.

Cab and Control

The cab is located on the front frame with a wide field of vision, and the inner side of the front wheels can be clearly seen even when the machine is articulated. The layout of the joysticks conforms to ergonomics, allowing the driver to operate multiple joysticks with one hand. It is equipped with a mechanical suspension seat, a high-power air conditioner, and multiple air outlets, providing high operating comfort.
