Doosan DX225LCA crawler excavator technical specifications and description

Description and features

During the development process, the manufacturer paid special attention to the build quality, which has a significant impact on the overall reliability of the equipment. Thus, all existing excavator elements are made only from high-quality materials using a variety of innovative technologies and modern equipment. Another equally important point is the comfort and safety of the operator. The manufacturer achieved all this through a well-thought-out cabin design and internal equipment, including various systems and functions.

In order to ensure greater productivity and efficiency of the equipment, there are two main operating modes. Let's look at them in more detail:

1. Standard mode. In this mode, the equipment uses 85 percent of the total power of the power unit. This mode can be called universal, since it is ideal for performing a lot of different operations.
2. Power mode. Unlike the previous one, this one uses 100 percent, that is, all the engine power. The main purpose of the power mode is to perform very labor-intensive work, which is often found in the mining industries.

The versatility of the excavator was also influenced by the hydraulic system, which provides the most precise control of the working bodies, which allows you to perform complex operations. We'll look at the excavator's hydraulic system in more detail a little later. The operating equipment control levers are equipped with special buttons that allow full control of the operation of additional units. The list of additional equipment is quite extensive and includes various crushers, grab buckets, hydraulic grabs, hydraulic breakers, hydraulic shears and much more.

The technique has gained quite a lot of popularity, both on the Russian market and on the world market. There is an explanation for this: the excavator is highly efficient and reliable, which ensures a very quick return on investment.

It is worth noting that in many ways the design of this excavator is similar to a more productive model, namely the Doosan DX300LCA. The common structural elements of this model and the Dusan 225 excavator are the following:

1. Track belts include self-lubricating sealed links and reliable isolation from various external contaminants, which extends their service life.
2. The manufacturer equipped the model with an X-shaped chassis, which has fairly high strength and rigidity. It is worth noting that 3D computer simulation and finite elements were used to develop this element. Due to this, an increased level of frame strength was achieved, as well as an increased service life.
3. The operator has a well-designed workstation with air conditioning, a padded, adjustable seat and a wide view of the work area.
4. The rotating platform of the excavator is made in the form of a D, since this design has increased strength and rigidity compared to a conventional one.
5. The equipment is equipped with a modern e-EPOS system, which not only improves productivity, but also the efficiency of the power plant.
6. The excavator boom has been strengthened and has a shape optimized using the finite element method. This solution made it possible to evenly distribute the load throughout the boom structure. Together with the high quality of the materials used, this had a positive effect on the increase in strength.
7. The main components of the handle have cast elements and reinforcements around the protrusions, which increased the service life and strength of the entire machine.

Now let’s return to the hydraulic system of the Dusan 225 excavator. Thanks to the modernization of this element, it was possible to achieve excellent results when interacting with the new switch and automatic power distribution system. The level of synchronization has been increased, making it easier to control the working bodies and increasing the accuracy of their manipulation.

Another important element of this excavator is the operator's cabin. Inside it there are all the necessary systems and electronics, through which the creation and further maintenance of favorable working conditions is carried out. A high-performance air conditioner with five different operating modes is installed here. In addition, the manufacturer has equipped the cabin with a soft seat, which can optionally be installed on an air suspension, which eliminates vibrations when performing any work. The seat comes with a special lumbar support and several adjustment functions. For operation in the winter season, a special heating function was used, thanks to which the most comfortable working conditions are achieved. Also in the cabin there is a special place designed for storing various tools and personal belongings of the operator. There is also a button to turn on the speaker system, through which the operator can also select a station, the desired volume level, or simply turn off the radio.

This element of the Doosan DX225LCA crawler excavator has the following:

1. Damping mount that reduces vibrations.
2. Lifting lower front window.
3. Ashtray and cigarette lighter.
4. Thermos.
5. Color liquid crystal display.
6. Handrails that increase the level of safety.
7. Sun visor.
8. Rear view mirrors.

Doosan DX225LCA crawler excavator

The Doosan DX225LCA crawler excavator is designed to perform a variety of loading and excavation work. The main area of ​​work of this technique is traditionally considered to be digging holes, trenches, ditches and creating dams and embankments. However, the model is often used for demolition of buildings, removal of old road surfaces, terrain leveling, and similar work. These problems have to be solved at construction sites and when performing repair and restoration work.

“Dusan 225” (also called Doosan) is used in public utilities and agriculture. Here the excavator is usually used together with additional equipment.

The equipment is tracked, which allows it to be used in hard-to-reach and waterlogged areas, on clay, sand and in wooded areas.

Modifications

In addition to the basic model, there are also some modified versions of the excavator. The most popular of all is the Doosan DX 225LCA-SLR modification. Unlike the basic excavator, this version has an elongated handle, so the equipment can be used for leveling the bottom of small reservoirs, deepening pits and trenches, as well as destroying large objects. Of course, all this can be done using the standard version of the excavator, but these tasks will become very problematic. To improve the stability of the modification, the manufacturer installs a bucket with a smaller capacity, since with a standard one there is a risk of the equipment tipping over.

About the nuances

The test specimen does not have hydraulic locks. Although, according to Sergei Rybin, they were on all previously delivered copies. They serve to ensure safety during boom operation. Blocks must be installed on the boom hydraulic cylinders and arm to prevent the boom from spontaneously lowering under load.

“This machine is only afraid of bad operators and particularly smart mechanics who climb into the excavator without understanding what to do with it. The main thing here is to monitor the oil level and carry out maintenance on time,” our expert smiles.

In addition, the test vehicle did not show the external fuel level scale inherent in Doosan technology. The fact is that the monitor shows an alarm about a lack of diesel fuel when there is 50 liters left in the tank. But the system does not provide the exact quantity. Therefore, the operator will have to focus on this level.

Price

The Doosan DX225LCA crawler excavator without mileage has a cost ranging from 5 million rubles to 7.5 million Russian rubles due to the year of production, version (basic or modified), configuration and installed working equipment.

Used equipment costs from 4 million rubles to 4.5 million rubles. At this price, you can buy a car from 2013 or 2014 in fairly good condition.

An hourly rental service varies from 1,300 rubles to 1,800 Russian rubles, depending on the cost of refueling, transportation, type of work performed and location of the facility. The cost of one full work shift averages 14,000 Russian rubles.

About service

Following the trends of technological breakthroughs, telemetry began to be installed on Doosan. A GPS receiver is installed in the cabin, which transmits not only the location, but also the parameters of the vehicle. And all this is included in the basic configuration.

The excavator is equipped with Parker high-pressure hoses in Extreme and Arctic versions. They can withstand even severe frosts. They rarely fail. Consumables include hoses that go to the boom handle. And that’s only because during operation inexperienced operators catch them on surrounding objects.

The fuse box is located in the cab behind the seat, so you can quickly check them if electrical problems arise.

For ease of lubrication of the main joints, wiring is provided.

The operator or mechanic can do this from just two points, and he does not need to climb up. Optionally, you can install an automatic lubrication system to eliminate the human factor.

You can overcapitalize the engine even in an open field. It is lined, and pistons or cylinders can be restored without boring.
