1. New natural suction engine powertrain is featured with stable torque output, low fuel consumption and low noise. The hydraulic system and engine power are matched and optimized to realize the reduction of comprehensive fuel consumption for excavating operations by more than 6%.
2. New load hydraulic sensitive system allows for improved maneuverability of compound actions, faster response speed, accurate control and small impact; it optimizes the main valve element and compensator, improves the arm speed of leveling compound actions, and makes the action speeds of boom and arm more coordinated and leveling performance greatly improved
3. High performance five-tooth bucket, with optimized bucket type, wider bucket, shallowed bucket depth, will reduce unloading time by 10%, increase bucket capacity and improve production efficiency by 5%.
4. Rotary torque is increased to improve the ability of slope operation. By increasing the displacement and pressure of the motor, the torque is increased by 15%, which makes the slope operation easier

Items of comfort improvement
1. All operating elements inside the cab are scientifically and reasonably arranged in accordance with ergonomics. For this tonnage, it is the first one that uses cab sunshade curtain,the industry's first enclosed sunshade curtain for 6-ton cab, it can avoid direct sunlight and protect drivers from all directions. At the same time, it can significantly reduce the air conditioning load in summer, save 3.8% fuel.
2. The seat package is improved, and the cushion is 20% thicker, which can improve the ride comfort and significantly reduce the sense of fatigue while working for a long time

More reliable and durable
1. Large area of high-strength tempered glass is used in the cab to improve the view of the driver while ensuring the intensity of cab. The top of the cab is equipped with lights to ensure accurate and safe work at night.
2. Strengthen the local area of boom and arm bearing high stress, and meanwhile adjust the structure, disperse stress and improve the service life; standard new-type bucket and reduced bucket depth make unloading quicker and faster.
3. X-frame structure is adopted for undercarriage. Large cross-section box is formed inside the lower frame through strengthened rib plate, which has good bearing capacity and the weight of the vehicle can be uniformly applied on the track roller frame to reduce its local stress concentration.

Maintenance improvement
Daily maintenance is within reach, convenient and fast.

Optional parts: crushing pipeline, hammer, refueling pump and rubber crawler block are optional to broaden the application fields of the machine.
