It is said that the quality of excavators is getting worse and worse now, not as good as before. Especially for the Komatsu-8 and Hitachi zx-3 series, ultimately it is due to the fact that these machines were previously imported, and now that they have all been replaced with domestic joint ventures, the quality and technology still cannot keep up. So now many people are buying imported products from JapanUsed excavator。
According to netizens' comments, he has one that usesKomatsu 200-7The machine is also good, but after buying a Komatsu-8 machine, it doesn't work anymore. It breaks down and burns an average of 20-22 liters of oil per hour.
Later, I heard from a friend that the Sumitomo engine was fuel-efficient, but the previous Sumitomo 3 engine was not very good. Later, with the idea of trying it out, I bought a Sumitomo 210-5, and now the fuel consumption is only 15-16. Over the course of a year, both drivers' salaries were saved. And it has been used for over three years without any problems, which is very reassuring. Moreover, the throttle of Sumitomo machines is controlled by a single knob, which is very troublesome for other machines to press for half a day on that computer screen. A slight abnormality in the machine can trigger an alarm. I still feel like Sumitomo machines are good
CAT machines are now expensive or gas guzzlers, they can't afford to burn.
There is also a Hitachi machinezx200I have been using it for 3 years now, and there are too many minor problems to fix.
Nowadays, Komatsu, CAT, and Volvo are not as good as before, and the import rate is low. They only sell brands and the quality is not as good as before.
The original imported Kobelco excavator is decent, with fast speed and fuel efficiency. The advantage of domestic production is fast speed, but the disadvantage is that the frame is not very solid.. Additionally, the newly released -8 series electronic fuel injection car is completely unusable
Doosan dh220, dh225, Dx300, dh55, Dh60, and dx60 are all pretty good. They are not very good at 70-80, 150, and 150. The service and accessory prices are quite good, and there are many accessories available in the market that come with them
