Mini Used Doosan Excavator DH55 Doosan Heavy Machinery Crawler
DH55 biggest feature
1.It is characterized by small size, flexible action, convenient operation, especially suitable for pipeline mining, slope dressing, and small construction in agriculture and forestry industries.
2. The DH55 uses a highly reliable Isuzu engine with strong performance, and the lifting capacity is improved by 21% compared with similar models.
3.The mature DH55 is based on the concept of "creating the highest use value for customers", integrating reliability and readiness, convenient maintenance and low cost.
Where the product is worth buying
1. The main pump with large displacement and high efficiency is installed to achieve efficient operation
2. The use of large capacity control valve, the speed is increased, to ensure that the machine in a variety of harsh conditions excellent operation.
3. Doosan's after-sales service is very good, with 370 offices in China to provide users with repair and maintenance services. It will not affect the progress of the user's work, once there is any small problem, after-sales service staff will be the first time to solve!

Advantages of DH55
1.Improve the profitability of user operations
Improve excavator operation efficiency and reliability For non-leasing users who do not take operation time as the engineering basis, improving product operation efficiency greatly increases the wealth brought by customers and creates more profits. Improving the reliability will ensure that the excavator will have more working time, and will not occupy too much downtime due to some failures or maintenance; Improving reliability also creates residual value for the brand and adds value to the user.
2.There are a variety of fuel-saving technologies, in addition to some hybrid technologies.
we can also reduce the cost borne by the user by reducing fuel consumption through the following technologies: First, make full use of the engine power, torque, fuel consumption characteristics of the curve, the operation point is set in the fuel saving area of the engine; The second is the use of electric injection technology injection precision to achieve fuel saving; The third is to set two levels of idle speed to achieve fuel saving as much as possible; The fourth is to optimize the pipeline direction of the hydraulic system and increase the pipeline diameter to achieve the purpose of energy saving by reducing the pressure loss of the fluid; The fifth is to set different engine speed adjustment according to the requirements of the user's operation mode to achieve the purpose of fuel saving.
3.Extend the maintenance cycle of the maintenance parts, reduce the investment in user maintenance.
We have done solid work and testing on energy saving and efficiency, and feedbacks from market users have brought obvious benefits to customers in terms of energy saving and efficiency, and even surpassed foreign brands in operational performance, becoming a successful model of Doosan technology application.
