In foreign countries, production began in early 2006, while in China, production began in mid-2007. Because of the influence of excavator situation under the general trend of EFI, in order to show his technical strength, Carter introduced EFI models, that is, black hydraulic cylinders were produced outside China in 2007 and in China at the end of 2008. Therefore, the yellow cylinder D machine was imported in 2007, while the domestic one was improved at the end of 2008.
2. Different years:
At the beginning of 2006, Japan began to produce D-type machines. Model C machine was introduced in 2000. Model D machine is divided into black cylinder and yellow cylinder. 320C is the second generation produced by China abroad since 2003. At the beginning of 2006, a change was made, that is, the third generation 320C.
In 2000, foreign countries stopped producing C-type machines for more than 1 year. The previous number was 320CHD, but after the official change, there was no HD, and there was an oil-water separator, which was the largest and yellowest. There is a cat logo in it. Imported ones don't have the above things. (because, at this time, foreign countries are already using D-type machines.)
Extended data:
From the appearance, mainly depends on the color. Imported colors are brighter, but domestic ones will be less bright after more than a year of use. In addition, the words CAT are printed on the chain bones of imported tracks.
The instruments and imported equipment in the cab can't be called out in Chinese, and the imported radio is printed with CAT logo, but it can only receive AM frequency. Deep bending barrel, made in China. It is also a standard bucket, and the domestic one will be about 2 tons lighter.
The imported Caterpillar has a metal plate of CEMA Japan Construction Machinery Association attached to its fuselage, while the domestic machine has a nameplate made in Xuzhou. The fuselage numbers of the same model, imported and domestic machines are different.
It can be seen from the joint between the hydraulic pipe and the forearm that the imported hydraulic pipe is painted before assembly, and the domestic hydraulic pipe is painted after assembly, so the imported hydraulic pipe is black, while the domestic hydraulic pipe is yellow.
Many foreign brands of excavators have factories in China, so there are differences between domestic and imported digging opportunities. In contrast, imported excavators are more popular than domestic ones, which leads some profit-seeking people in the market to sell all kinds of assembled, refurbished, counterfeit and domestic machines with import labels at high prices.
See if the small nameplate on the lower right of the cab is Japanese or Chinese. Of course, it's fake now. Maybe this small aluminum plate is sometimes fake. The screws on excavators are marked on both domestic and imported screws and can withstand different pressures.
The paint of imported excavators is very resistant to sunlight, because it is sprayed directly on the machine without putty. There is a lightning-like icon in the lower left corner of the front of the imported glass, with several strings of English next to it.
The display screens of imported excavators are all in Japanese, but Chinese can't be adjusted. In addition, there are descriptions of butter on the cover of the toolbox for battery and the box for air filter, which should also be in Japanese.
Check the machine number on the nameplate. If there are English letters in front of the car number, it is a domestic car. If there is no letter before the machine number, the machine number is imported. The three screws of imported Komatsu's driving wheel filled with gear oil are nuts, and the screws of domestic Komatsu are hexagonal.
