All of the listed modifications have their own characteristics, but it is worth noting that the basic variation of the excavator and the three latest models have gained great popularity. Let's look at them in more detail:

• Modification of Komatsu PC220-7. A distinctive difference from the basic excavator in this version is its technical characteristics, as a result of which the modification is in great demand. The digging power was increased by 20 percent, but the manufacturer reduced the rated power of the power plant to 125 kilowatts or 168 horsepower. But it is worth noting that this reduction does not affect the efficiency of the technology. The exhaust system has also been improved, resulting in the Komatsu PC220-7 meeting Tier II environmental standards. The level of extraneous noise and vibration was reduced by 5 decibels, which only increased the comfort of the car. In order to increase safety and improve the operator's working environment, the design of the cab windows has been changed: the right window does not have a pillar, while the rear one has been significantly changed. As a result, visibility from the workplace was increased by 34 percent.
• Modification of Komatsu PC220-8. A characteristic feature of this version is reduced fuel consumption. The manufacturer managed to reduce specific consumption by 10 percent without loss of engine power. But besides this, there were other improvements to the technology, namely, the level of extraneous noise in the cabin does not exceed 113 decibels, and the level of toxic exhausts was reduced by 30 percent. Two operating modes were provided:

1. Power mode (P). When operating in this mode, the power characteristics of the machine increase significantly, which provides the equipment with high productivity and reduced fuel consumption; fast operation of attachments, as well as high accuracy of work.
2. Economy mode (E). This mode helps reduce fuel consumption and also provides high-precision control and quick response of the excavator's attachments when performing simple operations.

• Modification of Komatsu PC220-8MO. The key feature of this version is the presence of six different operating modes. When operating in each mode, the engine speed and the power of the hydraulic system pump are interconnected. This is achieved through complete control of the powertrain, hydraulic system and electronics. All this has a positive effect on reducing fuel consumption by up to 5 percent. It is worth noting that this modification emits 30 percent less toxic substances, which is why it was awarded Tier III and Stage 3A environmental standards. In addition to all this, the excavator received improved performance characteristics, high productivity, and, of course, increased efficiency.

• Increased productivity. Engine power increased to 168 horsepower provides excavators of this model with higher operating speed. At the same time, low fuel consumption is maintained due to its efficient consumption in one of three operating modes: standard, maximum and hydraulic hammer mode.
• Maximum digging height. This parameter is more than 9.5 meters, which greatly facilitates the performance of all work for which it is necessary to raise the excavator boom high. This advantage is especially relevant for construction work, which is the main purpose of the presented model.
• Increased load capacity. The improved design of the seventh generation of special equipment of the PC220 series has greater lateral stability. This increases the lifting capacity of the excavator of the presented model by 350 kg: from 4.45 to 4.8 tons with a boom reach of 6.1 meters and a lift of 4.6 meters.
• Maximum traction force. This is one of the most important parameters of the hook. In this model, it is increased by 16% compared to the previous version and is now 20,570 kilogram-force (202 kilonewtons). At the same time, high precision and smooth movement of the machine when turning and the ability to climb slopes are maintained.
• Increased digging power. This parameter has been increased by 21% compared to the earlier version. This difference consists of a 9% increase in digging force on the bucket and a 12% increase in digging speed. This growth, in turn, ensures an increase in equipment productivity to 22 tons per hour.

Thus, the Komatsu PC220-7 is a more powerful, efficient and durable example of a specialized construction excavator than its previous version, the PC220-6. At the same time, it maintains the dynamic characteristics of its predecessors at the same level, without reducing them due to increased power and other power parameters associated with it.
