Tiedou Hitachi Excavators (Issue 1) Comparison of performance parameters of ZX8U-2. ZX10U-2. ZX17U-5A and ZX20U-5 Mini excavators

　　Hitachi is a Japanese engineering machinery manufacturing company. It has launched excavators, tire loaders, and road engineering machinery. In addition to the large number of excavator models launched by Hitachi, it has much fewer types compared to other engineering machinery manufacturers. Of course, in addition to engineering machinery, Hitachi is also involved in many large equipment, and has achieved good results and high evaluations in the industry. In this issue, we still focus on excavators. Why is this time introducing Hitachi Mini series excavators, with tonnage ranging from 0.8 tons to 2 tons? Today, these four official design drawings do not have a cockpit installed. It is understood that the original cockpit can be installed according to user needs. Some models cannot be installed, and the air conditioning system Mini model cannot be used. At present, many companies' Mini excavators can choose to install air conditioning.

　　However, from the data parameters, these Hitachi ZXmini excavators are equipped with Yanmar engines, and we can find that each engine model is different from other manufacturers. In the previous introduction of several issues of Mini excavators, many equipment are equipped with the same engine. Although the power is slightly different, there is a clear difference on Hitachi. The hydraulic pump flow rate is different with the increase of the model. The maximum hydraulic flow rate is also different. The size specifications and working range are not much different from other brands. The biggest consideration for Mini excavators is still the scope of application of the working environment and the stability and reliability of the equipment. The quality of Hitachi excavators is worthy of everyone's recognition. Tiedou Used Excavator Trading Co., Ltd. found in the manual test comparison of Japanese imports and other brands of Mini excavators in 2024 that Hitachi excavators are indeed better than some third-tier brands in material selection and process. The choice of cost also causes price differences.

　　If the budget is low, Tiedou still recommends that you buy a used excavator. At present, the price of Hitachi Mini excavators has a price advantage of about 60%-30% compared with Hitachi new machines. But you cannot enjoy Hitachi's original factory warranty. Users who pursue high quality should choose new machines as much as possible.
