Speaking of Caterpillar, no one in the construction machinery industry knows how many people want to own a Caterpillar excavator of their own. Carter's Excavator left the impression that the user is durable, strong, and Caterpillar's 20 ton model 320 Series, is also one of Carter's best selling models. Whether the new machine market or the two mobile phone market, Carter's 320 Series are very hot, from 320V, 320B, 320C, 320D and only before the domestic 320E excavator, can be said that Carter 20 tons of the excavator 名媛直播 of each series are classic.
Today, let's talk about the past and present of Carter's 320 Series excavator.
First generation 名媛直播: Carter 320V series
320V is the first generation of Carter's 20 ton series, probably on the market in 1993, and there are 320V1, 320V2, 320V3, and Carter 320V has been listed for more than 20 years. At present, there is little stock in the market, and there are only part of the V Series in Guangdong, Shanghai and other regions.
Carter 320V2
Carter 320V series excavators are imported models, which are not produced at home. This is also a batch of 名媛直播 Carter entered the Chinese market earlier, and got a good market feedback at that time.
Second generation 名媛直播: Carter 320B series
Carter 320B's excavator has so far stopped production for fifteen years, but in the two mobile phone market still can often see the voice of 320B, square shape, appearance is very high recognition. The appearance of the lines is very muscular, and black paint has been around the car for a week.
The 320B model was started in 1998, and was shut down by 2001, almost all imported cars. Why do you say that, because most of the 320B was imported from Japan, new cars and used cars, and even in Carter's Xuzhou factory, the model was produced, but it was just assembled, almost all the accessories were imported. It is precisely because of this, Carter's 320B has made a very good impression on domestic users. Even if it has been shut down for 15 years, there are still users in the market looking for 320B excavators.
Carter 320B excavator vehicle weight 19.4 tons, the original car capacity is 0.94 parties, using the Caterpillar 3066T engine (Carter's Excavator from the surface to see the use of Carter's own engine, in fact, the majority of the Japanese MITSUBISHI heavy industry, some engines can see the MITSUBISHI logo), the rated power of 99.9 KW.
On the hydraulic system, Carter 320B has moving arm priority and rotary priority function. These two functions are also available on current excavators, with fine control mode and driver mode in operation mode, and fine control mode is especially suitable for hoisting and fine operation. In terms of maintenance, Carter's recommended maintenance time for the 320B excavator was 250 hours for ordinary maintenance and 500 hours for hydraulic oil filter.
It has to be said that the import is good, the configuration is more than the domestic production excavators, such as the current two mobile phone market can be seen that many excavators have weighing function, and the data is very accurate.
Third generation 名媛直播: Carter 320C series
After Carter 320B's 320B shutdown in 2001 (or to let 320C go public to stop 320B), Carter launched the third generation of 名媛直播 - 320C, which has a higher share in the current mobile phone market, and many users are even looking for this type of user to work on the mine.
Focusing on production time, Carter 320C excavator production lasted for five years, from 2001 to 2005. Why do you want to emphasize it, because this car has been stopped for more than 10 years, but in the second-hand car market, there are many people who are looking for this car, and there are many people who are looking for it. It can benefit more than tens of thousands, and more than one hundred and two hundred thousand. So if you see the user who wants to buy the Carter 320C excavator, please be sure to polish his eyes. If the car said it was produced in 2008, then weigh it up.
Carter 320C used the engine of Carter's 3066T, but the power is higher than 320B, 138 horsepower, the conversion success rate is about 110 kilowatts, the most intuitive power to improve the sense of power is stronger. But the parameters of the large pump have not changed. The maximum pressure of the large pump is 34.3 Mpa. The rated flow rate of each pump is 185L/min, the same as 320B. But in turn, it is better than the 320B series. The 320C rotary pressure is about 25Mpa, the rotary torque is 60.9KN/m, which is better than 320B at the rotary speed and the rotary torque.
More importantly, the hydraulic system of Carter 320C uses the boom and bucket rod return oil recycling circuit, which makes the operation cycle time faster. In terms of maintenance, 320C is also more economical than 320B, the recommended maintenance time is 500 hours of conventional maintenance, hydraulic oil filter 1000 hours a change.
In appearance, the Carter 320C excavator also changed a lot with 320B, if the "Founder rigid" description of 320B, then 320C can be regarded as "smooth".
Fourth generation 名媛直播: Carter 320D series
Carter 320D should be the more common 20 tons in the current market, and 320D series excavators also have several models, such as 320D, 320DL, 320D2, 320D2GC, 320DGC, so what are the features of these types of excavators?
First to say Carter 320D and 320DL 320D and 320DL, 320DL is the chassis strengthened version of 320D, the use of lengthened and broadened track, from 2006 production (foreign for the start of production), 2014 production, using the engine of C6.4, the power is less than 320C, to 103 kilowatts, the original car capacity of 1 parties, at that time the price of about 110 About ten thousand.
Carter 320D excavator has electric spray model also has a direct injection model, in the D series of engine configuration is rich, consulted some of the Carter agent's friends do not have very detailed information, generally still need to rely on serial number query. Probably in 2007 and 2008, the direct injection machine was produced, and it was produced in 2008 to 2011.
320D GC
In 2010, Carter launched a "earthwork" 320D GC excavator suitable for local work for Chinese users. This model is designed for earthwork, oil consumption is lower than 320D, but the strength of the whole machine (including the brachial arm, chassis and so on) is lower than that of 320D, so it is not required to be used in the mine when it is sold. Homework, otherwise no warranty. Of course, the price is much lower than that of 320D, about 1 million.
Carter 320D2
The Carter 320D2, an upgraded version of the Carter 320D, was launched in Xuzhou in May 2013, using the Carter C7.1 engine, with power up to 112.5 kW. The engine was converted to a direct-injection engine, which saved about 3-5 litres of fuel per hour compared with 320D, and air pre-filters were added to the original plant.
Carter 320D2GC
The 320D2GC is also on the market in 2013, using the Carter C6.6 engine, is also a suitable for earthwork operations, based on the 320D2 modification.
The fifth generation 名媛直播: Carter 320E series (not yet listed in China)
Carter 320E has not been listed in China, but the E series of small dug has already been listed in China, such as 305.5E and 307E. It is said that the Carter 320E excavator currently listed abroad uses Carter C6.6 engine, the maximum pressure pressure is 35 MPa, equivalent to 320D, the flow increases the working cycle faster, and matches the regenerative loop of the arm and the bucket.
Comparison of Carter 320D and Carter's 320E parameters
In appearance, Carter 320E and 320D are particularly distinct, the fuselage is much higher than 320D, and the dashboard is more modern. This car is probably listed in Japan in 2013. There are a small number of imported models at home, but so far, it is still a relatively rare vehicle at home and when it will be imported from domestic production. There is no news about whether the domestic development will be introduced. But given that Carter's 320D sales in the country are not particularly ideal, some industry staff may even analyze the possibility of not introducing domestic or waiting for the next series of 名媛直播.
Looking back at Carter's 320 series of development history, almost every generation has a very good market performance, 320V, 320B and more than ten years of the age of the excavator in the market is not uncommon. At present, the market trading volume is relatively frequent 名媛直播 also have Carter 320C and Carter 320D, this is the market for Carter 名媛直播 recognition, can do so in addition to Carter should be small pine, hope independent brand 名媛直播 to speed up the rise, to the people's prices to provide users with high reliability 名媛直播.
