Japanese excavators haveKomatsu，HitachiSumitomo,KobelcoKato's 5 major brands. Which of these brands is good to use has always been a topic of debate among many people. They all have their own strengths in performance, and their popularity in China is relatively high.
Below, we will analyze the differences between these five major brands in terms of engine, hydraulic, oil pump, circuit, durability, and fuel consumption:
1. Komatsu uses Cummins, Hitachi, and Sumitomo use Isuzu, Kobelco, and Kato engines. We use Mitsubishi, and now Kobelco also uses Hino's. So Komatsu engines are a weakness.
2. Hydraulic Komatsu is the best, with advanced computer board and fast speed. The rest are similar.
3. In terms of oil pumps, Komatsu is better than Hitachi. Kobelco, Kato, both are okay.
4. In terms of circuits, Hitachi and Kobelco are complex and difficult to repair after aging.
5. In terms of durability, Kato is the most durable, while others are similar
6. In terms of fuel consumption, Komatsu is relatively large, Hitachi is relatively fuel-efficient, and Kobelco is the most fuel-efficient, but its strength is not strong. It won't work when you touch a stone.
Overall, the quality of imported machines is similar, with no obvious advantages or disadvantages, and each has its own strengths. To be honest, when buying excavators, don't try to be cheap. There is a reason why imported excavators are expensive.
In recent years, due to changes in the business strategies of the five major brands and adjustments to the domestic market, Komatsu, Hitachi, and Kobelco have surpassed Kato and Sumitomo in terms of user share in China. Of course, it's not that Kato and Sumitomo machines are bad. Due to the strong rise of domestic brands, some manufacturers have had no choice but to selectively abandon the Chinese market.
