Used 2021 XCMG XE80DA wheeled excavators
Product Introduction
XCMG XE80DA excavator is widely used in small-scale earthwork engineering, municipal construction, road repair, concrete crushing, cable burying, farmland water conservancy construction, garden cultivation and river ditch dredging and other projects.
Product features
1. It adopts Yanmar naturally aspirated engine widely used in the industry, with small displacement, low fuel consumption and high low-speed torque, which perfectly meets the characteristics of excavator operating conditions. The engine adopts direct injection technology and has good oil adaptability. Upgraded from mechanical speed regulation to electronic speed regulation, the speed control is more stable, which not only reduces fuel consumption, but also effectively reduces the “black smoke” of the engine.
2. For the first time in the same tonnage product industry, the electronically controlled main pump is used to control the maximum load torque of the main pump according to the maximum output torque of the engine at different speeds, truly realizing the perfect match between the load and the power output, and greatly improving the utilization rate of engine energy .
3. The hydraulic control system uses an advanced load-sensitive control system with low energy consumption, fast response, precise control and small impact. According to the load feedback signal, the output flow of the variable plunger pump is controlled to always meet the opening of the spool of the multi-way valve, without redundant flow loss, and to achieve flow distribution independent of the load, which is more flexible and flat. Actions are easier to implement.
4. Compared with the C series products, the new generation XE80D has a bucket capacity increased by 10% to 0.33m3, which improves the efficiency of earthwork operations. Larger fuel tank capacity, combined with ultra-low fuel consumption, prolongs the continuous working time of the whole machine. According to the improved and upgraded hydraulic system, the volume of the hydraulic oil tank is re-optimized, which is 11% lower than that of the C series products, and the maintenance cost is greatly reduced.
5. Partial strengthening is carried out on the part of the boom with high stress. The stick is made of molded “U-shaped plate” and the upper cover plate, which has a longer service life. The standard new bucket makes unloading easier. The main beam of the slewing platform adopts the “I-beam” structure, and the side beam adopts the “D-shaped cross-section” structure, which has higher overall reliability. The X-frame chassis structure is adopted, and the inside of the lower frame is reinforced with ribs to form a large-section box, which has good load-bearing performance and can evenly apply the weight of the upper car to the track beam, reducing the local stress concentration of the track beam. . The international standard reinforced crawler is adopted, which is more reliable in use and more convenient in maintenance. The newly added air intake pre-filter can effectively filter large particles of impurities into the air filter, prolonging the service life of the air filter. Equipped with a large Euro III high-precision fuel primary filter with an oil-water separator, the filtration area is 1.5 times that of other models of the same tonnage.
