- The China-III compliant power system, the percentage accelerator control, and the fully electronically controlled positive flow hydraulic system feature reduced energy loss, high efficiency and energy-saving, and good motion coordination. The paralleling radiator is adopted to effectively prevent the overheating. The exhaust system is optimized based on the Fluent simulation to reduce the exhaust noise and improve the engine power utilization efficiency. The transmission route is optimized based on the MATLAB vibration system simulation principle so that the noise level of the machine is superior to CE standard requirement. The three-stage integrate fuel filter and the electric fuel pump guarantee the good fuel adaptability and effectively protect the engine.
- Product reliability: The high quality core parts and the design optimized working device feature stable and reliable quality.
- Operations and maintenances: The large color display can real-time monitor the working status of machine mode and incorporates the malfunction self-diagnosis and record function. The multi- stage power control is adopted for the manual and electronic accelerators so that the user can select different working modes depending on own needs. The intelligent information terminal of excavator, eases the management of the excavator. The diversified optional attachments, including breaking hammer, ripper, and quick change device, can be equipped to realize the digging, landfill, breaking, and leveling operations, featuring multi-function capability. The remote installation locations for the maintenance parts ease the maintenance operations.
- Comfort: Within the spacious cab, the arrangement and color matching of the upholstery are designed as per the ergonomic principle. The full-automatic A/C system, automatic air vent adjustment and distribution, and height and position adjustable seats feature excellent adaptability. The cab is equipped with composite shock absorbers to effectively mitigate the vibration of the cab.
- Appearance: The all-new modeling is designed as per bionic principle and is covered with fully molded and electrophoresis treated coverings.
