1. New power
Excellent power system, equipped with Isuzu 6HK1 engine, rated power of 210kW, large displacement torque, strong power;
Full electronically controlled hydraulic technology is adopted to improve coordination and flat performance.
2. New technology
The bucket is newly upgraded, and the rock bucket is equipped as standard to achieve "one bucket in one condition", optimize the bucket type, and increase the excavation efficiency;
Direct power control technology is adopted to dynamically adjust according to the load, reduce waste and achieve energy saving.
3. New shape
At 10 o'clock, the large screen was upgraded again, with a high degree of system integration, and the car was equipped with a wireless LAN;
Equipped with a new air-conditioning system, smaller size and stronger cooling effect;
The interior is fully upgraded, with narrow armrest box, minimalist front control box, standard cup holder, 24V power port, USB interface, etc., with automotive-grade quality interior;
The appearance is upgraded, the cover door is heightened, the side door is strengthened, and the engine cover and toolbox cover are assisted by gas springs, which makes the opening process more labor-saving.
