The 5 Japanese Komatsu Mini excavators introduced today are still niche models. Slightly different from the 1-ton excavators introduced in the previous issue, the excavators under 2 tons have a wider working range, but considering the engine power of 11.2Kw-14.5Kw, it is also suitable for indoor and relatively easy work. After all, the Mini excavator is mainly used to solve most minor work. Although some manual labor can be replaced, the work efficiency is far less than that of the Mini excavator. Moreover, the reputation of Komatsu Mini excavators in the industry is very outstanding, with reasonable mechanical matching, high mechanical quality, and work efficiency. Compared with the top Mini excavators in the industry, it is not inferior at all, and even has unique advantages in individual technologies, low failure rate, long service life, and high value retention rate. In 2024. Tiedou used the excavator market Komatsu Mini excavator is the top three in popularity. In terms of user feedback information, there is no bad review except for special circumstances.
From the PC10 series to the 20UU series, the design and operating comfort are very good. The size of the Mini excavator is limited, and the driving seat is on the engine. The small space makes the seat less comfortable than that of a large excavator, but the Komatsu operation feels very relaxed and does not make people feel too tired after working for a long time. Of course, users can customize the time, but air conditioning cannot be installed, and outdoor work is still very limited. If you need a Mini excavator, Komatsu is a very good choice.

Digging capacity: Digging depth and digging height are also different. PC20MR-5 and PC20UU-5 have the largest digging depth and height.
Hydraulic pump brand and model: All models use Komatsu hydraulic pumps, but the specific types and flow rates of the pumps are different, reflecting different operating requirements.
The above models are not very different in performance and specifications. Limited by space and work type, fuel consumption and many other factors need to be considered. They are fully capable of meeting indoor and easy work. Komatsu PC10-20 is not equipped with lithium batteries for the time being and belongs to conventional power. If users are interested in lithium battery excavators, they can choose PC05 and PC30 series. We will briefly introduce them to you in the next issue. In the Tiedou used excavator market, Komatsu Mini excavators have stable prices, high market recognition, reliable performance and excellent performance. If you like Mini excavators, Komatsu can be considered.
