Most of Hitachi's new conventional version excavators are sold in Japan as US or UR versions, and in addition to these versions in other countries, Hitachi will find that many models are very popular in some countries in Europe, the United States, China, Africa, and the Middle East, but are rarely seen in Japan. The conventional versions of Hitachi ZX60 and ZX70 series are very popular, and the implementation standards and environmental protection requirements of different countries are different. The several excavators introduced today are all equipped with Yanmar engines. If users who know Hitachi well know that almost all excavators of Hitachi's previous generations are equipped with Isuzu engines. We don't know why the engine is replaced now. In order to meet the fuel consumption and emission requirements, the Yanmar engine is now equipped with full electronic speed control, which has a significant improvement in fuel consumption control, noise and temperature. In the hydraulic system, Hitachi is equipped with an independent rotary three-pump hydraulic system, which is obviously smoother in operation and combination of actions.
Hitachi's interior design still adopts the traditional layout, and it can be said that the changes are not big. The traditional display screen inside the cockpit is still a bit backward. Compared with the color LCD screen used by most excavators today, Hitachi seems a bit old-fashioned. In terms of appearance, except for a few decorative modules that can prove the difference, the gap between the previous generations of excavators is not big. However, some are not the focus. The core of Hitachi excavators is still stability and performance. In the past ten years since I came into contact with Hitachi excavators, I have trusted Hitachi very much. Tiedou has used excavators. In the past ten years of work, I have come into contact with many Hitachi excavators, from the initial EX series to the Hitachi ZX series. The most impressive is the Hitachi ZX70-6 series. When operating Hitachi, you can obviously feel that it is different from other excavators. The noise control of the engine and the relaxed feeling at work make the use very confident. Many users still like Hitachi very much.
It is not bad for us to purchase some technological combinations and advanced technologies for excavators. However, the failure rate of excavators is high, and the maintenance cost is high. For many users, overly complex technologies are not friendly. Stability and life are the key cores for users. Hitachi will not disappoint users in this regard.
Tiedou introduces these Hitachi ZX75US-7. Hitachi ZX75UR-5B, Hitachi ZX120-6. Hitachi ZX120-7. Hitachi ZX135US-6. Hitachi ZX135US-7. Hitachi ZX135USX-7.
