Hitachi, Komatsu, Kobelco excavators have several new mid size excavators equipped with electronic fuel injection engines. Below are three of them introducedUsed excavatorAdvantages and disadvantages:
Komatsu 200-8 excavatorThe 6-cylinder electronic fuel injection engine has high fuel consumption, and this car is also my own. The engine has a good hydraulic system, good mechanical matching, moderate power, and fast speed. Komatsu is most proud of their hydraulic system. There's no need to mention the earthwork, is the rock excavation okay. Komatsu's work has been declining from generation to generation, with poor quality in terms of iron parts and many areas experiencing paint peeling and rotting. Among all Japanese 200 car series, its bucket is the largest. Among the more than 900000 yuan electronic fuel injection car series, Komatsu is the most valuable, and the price of a second-hand car is not much lower than that of CAT. There's no problem digging or breaking. If Komatsu vehicles are used for a certain period of time and not protected, electrical problems are likely to occur, making it difficult to repair Komatsu's electrical system.
Zx200-3 excavatorThe 4-cylinder electronic fuel injection engine has high fuel consumption, average mechanical compatibility, fast and sensitive movements, average hydraulic system, and moderate to high power. The driver's seat of the Hitachi car is much shorter than other cars, and the excavator leveling is easy to find. There are many of these cars in our area, and I personally think that the Hitachi electronic fuel injection car is the least mature. We have repaired many Hitachi oil nozzles here, so now we have replaced them with ZX200-3G. Almost the same oil is used, but Hitachi has repaired more oil nozzles. The biggest common problem with Hitachi is that the main control valve starts leaking oil after thousands of hours of use. There is a saying about fried Hitachi. Value preservation is average
Kobelco Excavator SK200-8The 4-cylinder electronic fuel injection engine has the lowest fuel consumption among electronic fuel injection vehicles. The hydraulic pressure of the engine is average, the speed is fast, and the mechanical compatibility is average. A typical car can level and perform light tasks quickly, with particularly fast rotation. A typical car may not be able to do some light work as well as Kobelco, but if this car encounters excavator loess, its strength will be reduced. This car only needs to be used for earthwork, but it won't work when going up the mountain. Now the engine is also produced domestically, and walking is the worst part of Kobelco.
