1. The engine adopts a naturally aspirated engine widely used in the industry, with small displacement, low fuel consumption and high torque at low speed.
2. For the first time in the industry, the electronically controlled main pump is used to control the maximum load torque of the main pump according to the maximum output torque at different engine speeds, which truly achieves a perfect match between the load and the power output, and greatly improves the utilization of the engine energy.
3. The hydraulic control system adopts an advanced load-sensing control system with low energy consumption, fast response, precise control and low impact.
