3. Core advantages

Power and efficiency:

Equipped with a high-power engine and hydraulic transmission system, the bucket digging force reaches 8800 kN and the digging force of the bucket arm is 6300 kN, which can adapt to complex working conditions.

Economic mode (E0-E3 gear) and fast mode (P gear) are optional to optimize fuel consumption and operating efficiency.

Control and comfort:

The electronic control system is adopted, and the operation is precise and flexible; the 7-inch color LCD monitor supports multi-language display to enhance the human-machine interaction experience.

The cab is equipped with an air-conditioning system and an ergonomic seat to reduce operating fatigue.

Durability and maintenance:

Key components such as the cooling system adopt a parallel design to avoid overheating; the modular structure simplifies the maintenance process and reduces maintenance costs.

The fuel pre-filter element with oil-water separation function is standard to extend the engine life.

Multi-functional adaptation:

Optional accessories such as a breaker hammer can be used to expand the operation scene.
