Features of mini excavator:
1. with stere reinforced shovel whose key parts increase the thickness of the steel plate adopts advanced manufacturing technology to improve the durability.

2. Large and robot welding arms, key areas of reinforcement.

3. The European and American version of the cab is 10cm wider than the conventional version, providing a wider view and reducing fatigue by 20%.

4. The imported control valve from South Korea, high performance rotary motor, and optimized hydraulic system make the rotation strong and powerful, and the operation more excellent.

5. Optimizi the parallel design of heat dissipation system to ensure the optimal operating temperature of the engine.

6. Optimize the intake system, strengthen the material of the filter element, achieve a filtration accuracy of 99.9%, and extend the repalcement cycle by 15%

7. Hydraulic system, high efficiency and energy saving, machine, diesel filter centralized maintenance, save time and worry.
