How should we choose between Hitachi ZX200-5A and ZH200-5A

Why buy Hitachi? More people say that Hitachi has a good heart and Isuzu engine. So why do some people not choose Hitachi? The vast majority of people think that Hitachi is too prone to oil leakage, although the oil leakage problem is not very serious. The customer said that once Hitachi leaks oil, even if the original piping is replaced, it is still difficult to completely eradicate the problem. This is why many of us are afraid of oil spills. But here we can tell everyone that in terms of daily failure rate, problems such as oil leakage and seepage can be considered very small and common.

Domestic joint venture new modelThe overall appearance of the new 5A model has not changed much, and the cab still adopts the traditional structure and Hitachi style driving structure. In terms of appearance, the Hitachi 5A has undergone some changes in details, and the stickers on the body make it easy to recognize the differences between the new and old models at a glance. So which one should we choose between the ZX series diesel version and the ZH series hybrid version launched by Hitachi on the 5A model. Here is a brief explanation of the working principle of hybrid vehicles, which is similar to the commonly used hybrid vehicles,

　　The ZH series hybrid models rely more on a generator to provide power output. If used solely in earthwork projects, the hybrid model not only has an efficiency not lower than the pure diesel version, but also has lower fuel consumption than the diesel version. It should be noted that the residual value of hybrid power is in a very awkward position, just like that of cars. The price of second-hand hybrid excavators is not high in the market. The residual value also gradually decreases as the market matures. When purchasing ZH series products, one should also pay attention to maintenance issues. Some friends in remote mountainous areas can basically give up hybrid models. If there are problems with the circuit system, it is not something that ordinary mechanics can solve.

Focus on Hitachi hereZX000-5A diesel version, this model uses Isuzu GI-4HK1XKSA-03 engine with a rated power of 2000/113, which reduces the power by nearly 12kw compared to the previous generation. However, we need to know that although the most important hydraulic power flow is lower in power compared to the previous generation model, it has the same efficiency as the previous generation. It should be mentioned that the fuel consumption has significantly improved compared to the previous generation, and this model is the top choice in terms of emissions and environmental protection. With the addition of the new Isuzu 4HK1XKSA-02 engine, it can be said that this model has absolutely no concerns for daily use, and some details still need to be tested by the market. And the main pump of the new model adopts two variable axial piston pumps and a gear pump. The hydraulic flow rate of the main pump is 30.2I/min 2 × 212 higher than the previous generation to eliminate some future use problems. It is recommended that everyone pay attention to and compare the Hitachi ZX series medium-sized 5A in detail.
