1. The 6HK1 engine is selected to meet the national three emission standards, with more powerful power and high reliability
2. The main hydraulic components adopt top configuration
3. The positive flow control system is adopted, the control is more precise, and the operation sensitivity is higher.
4. Through the reasonable matching of the large displacement pump and the electronically controlled positive flow valve, the hydraulic system has stable performance, low pressure loss and precise control.
5. Adopt large-diameter pipelines to reduce flow resistance and fuel consumption
6. The display and control system are upgraded. The main controller adopts KC-MB-21. The operating speed cycle is 20ms, which is much higher than the 40ms in the same industry. The reliability is higher, the power matching is more accurate, and the fuel consumption is greatly reduced.
7. In order to adapt to different working conditions, the heavy load mode with priority of efficiency (H mode), the economic mode with priority on fuel consumption (S mode), the light load mode with fine operation (L mode), and the crushing mode with on crushing (B Mode) and other operating modes, easily cope with various working conditions
8. The heat dissipation system is fully upgraded, and the heat dissipation capacity is significantly improved to ensure that the temperature of the engine and hydraulic system is stable under various working conditions, extend the service life of the engine and hydraulic system, ensure the reliability and stability of the whole machine, and greatly reduce the overall temperature. Machine noiseThe whole machine vibration and noise
9. The new type of cab is equipped with a luxurious suspension seat, which optimizes the strength and structure of the pilot control system through ergonomics, which greatly relieves the operator's fatigue
10. Fully optimize the process of structural parts, curing operation process and parameters, and fully adopt high-performance welding robots for automated welding
11. The cross-section of the working device adopts a reinforced box structure with a larger cross-sectional area, and the working device adopts a forging and welding structure with higher strength
12. The boom and stick cylinder adopts a new type of bushing with high surface hardness and high surface hardness and double-layer anti-friction measures with oil storage holes
13. Comprehensively improve the reliability and performance of each hinge point, reduce hydraulic loss, and realize the stability and durability of structural parts
14. Through the optimized arrangement of maintenance parts, daily maintenance saves time and effort.
