1. Original imported engine, combined with high-quality original imported hydraulic components, adopts an advanced and reliable positive flow control system, providing the equipment with stronger excavation capabilities and ensuring high-efficiency operation.

2. Compared with the same level of products, it has greater excavation power, can adapt to complex mining and mining, and provide customers with higher returns.

3. Key large heavy-duty structural parts such as chassis, slewing platforms, and working devices adopt fatigue resistance design. Through fatigue simulation coupled with residual stress and working stress, fatigue life prediction and structural optimization are achieved, and the fatigue life and reliability of large structural parts are improved.

4. Key components such as engines, pumps, valves, reducers and other key components are equipped with global high-end equipment, ensuring the reliability of the entire machine and meeting users' requirements for high equipment attendance.

5. Reasonable and convenient channel design to meet equipment maintenance needs. Double-mounted car access, redundant design, ensuring that users can get on and off the car easily. The engine exhaust dust discharge device is standard, which can meet the 30-hour ultra-large diesel tank. It is standard with automatic lubrication, which effectively reduces maintenance time.
