Doosan 225

The manufacturer of various special equipment Doosan uses only high-quality materials, modern innovative solutions and improved equipment in the process of creating its products. But during development, special attention is paid to comfort and safety during operation.

Thanks to all this, the manufacturer managed to take a leading position in the markets and win the trust of customers and clients.

One of the most popular machines produced by this company is the Doosan 225 crawler excavator, which is designed mainly to carry out all the necessary work related to loading and digging various soils.

Under the hood of the Doosan 225 excavator is an advanced power unit of the DB58TIS brand. This engine is the manufacturer's own development. In addition to the main elements, it has the latest electronic control system, which has been named E-EPOS. The maximum power marked on the flywheel is 110.3 kilowatts or 150 horsepower.

In Russia, this excavator model has gained great popularity due to its fairly high performance characteristics, efficiency and reliability, which ultimately allows you to quickly recoup the money invested in purchasing the machine.

Peculiarities

Each excavator caterpillar contains self-bonding sealed links, which provides fairly high isolation from various industrial contaminants. The chassis of the machine uses an X-shaped design and for good reason, since it is this structure that ensures a long service life and high reliability.

The cabin has a comfortable seat that can be adjusted in almost all parameters (an air-suspended seat can also be included in the package); an air conditioner is installed, providing comfortable conditions in the cabin when working in various weather conditions (there are five modes in total); there is a heating system, which is an indispensable option when operating in cold weather; The cab glazing area is quite large, thanks to which a wide visibility from the operator's workplace was achieved. In addition to all this, an audio system is also included in the basic package.

It is also worth noting such a new product in the Dusan line of equipment as the E-EPOS control system, which allows you to reduce diesel fuel consumption, not only without loss of power, but even with an increase in machine performance.

Price new and used

In a completely new technical condition, this excavator is quite difficult to purchase due to the small amount of equipment on the markets. But the cost of such a car starts from five million Russian rubles.

A used excavator costs from three million to five million Russian rubles. The main factors on which the price of equipment directly depends are the technical condition, operating time and year of production.

Purchasing such an excavator is often problematic due to its rather high cost, and therefore such equipment is most often rented. One hour of work can cost up to 1800 Russian rubles.
