With the growing maturity of the domestic excavator market, more and more users begin to focus their eyes on the second-hand excavators, especially the original used excavators in Japan. Recently, our factory has received many questions about the used excavators. Today, the mini excavator maintenance plant has been compiled for 15 years in Xichang. How do you identify the imported second-hand excavators in Japan and summarize some valuable "tricks" for the second hand excavators, hoping to play a reference role in the selection of second hand excavators in the future.
When you see the so-called second-hand excavator in the market, how do you decide? First, you want to see the overall situation of the car, do not rush to start the car to see the action, you want to see the car's appearance, to judge whether the artificial refurbishment or the chassis is original, this is very important, a hard excavator will not refurbish the body and change the chassis. There are many examples of the walking system. Now some traders put in the two mobile phone piles in the heap of used cars that have been collected in the field or used for about 2 years or so.
Maybe someone will ask me how long it will change the chassis crawler? My experience is: a secondhand excavator takes about 4 to 6 years in your hand, and the occasional Dry Hill project will change the track, except for the whole year, but how can a car change the track and the refurbishment? That's the only way. With personal experience, it is natural to have long experience. New users must bring an experienced mechanic or repairman when looking at a car.
Then look at the cab, because the cab is the most frequent part of the driver in a car, without too much wear and wear, the cab will be very neat, which means that the car is not tired, this is the most simple part of the judge of the quality of the car.
All right, the next step is to start the engine. When you hear the motor sound is clean and the hydraulic pump doesn't sound different, be sure to pay attention to it: if the hydraulic pump screws are screwed over, especially the large area wring marks, the car can basically be removed from the candidate list, and do not try again, when you give the action, when you give the action, each If the condition allows the best to work for a few hours, then you can see whether the rotary motor distributor has screws over or the trace of the oil.
Now let me explain what kind of second-hand car is worth buying.
Many newly entered people have misunderstandings, think the closer to the car, the car conditions will be better, in fact, in Japan, the excavator like a car is the same account, is to have an annual inspection, each car work time, whether or not the annual inspection of these car conditions are to have a record, working time to a certain period will be forcibly scrapped, this In any one of the problems, the Japanese customs will not put the car, so when buying a second-hand excavator, we must look at the used excavator documents that the manufacturers must show. In Japan, the excavators like the friends of the Sumitomo or Hitachi company will be recovered by their own manufacturers, and then they will be auctioned by the auction. This is the normal import process of a second-hand excavator.
The other is that there are many large rental companies in Japan that are not recycled or sold by auction. In Japan, the individual users can rent the equipment. Like a taxi, the car has a good maintenance. My friend has seen that the car has been sold and the car rentals are still playing butter. This is a personal quality problem. If in the country, like such a car renting method, car rill will not be managed, the quality of the Chinese people need to be improved, including myself, of course, these are all out of the question.
So why do we have nearly 20 years of second-hand excavators? Hongkong owners are rich in money and are doing much more. They buy excavators at the whole site, and some even buy 3 to 5 excavators. That's why I've seen a 28 thousand hour excavator.
When you buy a used car, you only need to ask the working hours and test the car conditions, there is no need to ask the question. I used to meet a lot of people like this, so how do they carry the 20 year's car into the mainland? Do you have to pay the tariff? I don't know, I don't care so much, I bought a second-hand car anyway. How did he manage to get in? I only asked for good condition and good price.
In 2001, when I went to Shenzhen to buy a car, I was surprised that the roadside excavators were old models of Hitachi -1 or Komatsu -3. At that time, the Tianjin Komatsu -5 had been very rare. I asked the owner of Hongkong, the owner of the car, who was just squinting and laughing. On the second morning, he pulled me to a fishpond to see a car. There were a lot of things. My home excavator is refurbishing, there are many accessories shop, there are various types of excavators in the car, I suddenly suddenly realized that they have formed the industrial chain of assembling the refurbished and disassembling one dragon, the car is not afraid of the old, as long as it is pure second-hand, it can be used, the old car accessories are better looking for!
The following is a summary of my more than 10 years' experience on the use of Japanese pure - used excavators for various brands, not including joint ventures and excavators that sell only to the mainland:
Hitachi: 200-5 model excavator leather, but oil leaking everywhere, easy to repair spare parts to buy and not expensive, EX60-2, EX60-3, EX60-5, these models use NISSAN engine, and the Isuzu engine, is my favorite engine, under the same conditions, MITSUBISHI engine is not as durable as the NISSAN and the Isuzu engine.
Komatsu: Komatsu's small excavator must not be bought. The small dug in the early side of the Komatsu is fine, and the small dug is slow after the small dug. Now I don't dig in the Komatsu. Only the customers in the northeast and Shandong occasionally ask Komatsu to dig. I really can't understand that they are really used or hearsay Komatsu. Small digging? OK, Komatsu. I haven't used it.
Caterpillar: personal feel the most solid small excavator is Cat 70B, I have seen the use of more than 20 thousand hours of Cat 70B, all kinds of parts are still very good.
Sumitomo: SH60-2 Sumitomo dug personal feeling is a broken car, can be dug with Komatsu, we do not fall well, we have not fallen here, Sumitomo Model 200 type of excavator like A1 or A2, the car is very leather, is the strength of the difference, if the mountain is not suitable for Sumitomo, Sumitomo A3 this model is not very strong.
Kobelco: do not say, if the circuit problems will rush you to death, the boss of excavators and accessories is Kobelco's small dig shook his head!
All the above mentioned are imported Japanese domestic production and use of excavators, many of the so-called imported original vehicles, in fact, are three quality excavators produced in Taiwan or Indonesia. In Japan, the first class cars are made in Japan, their own cars are supplied to the country, and the two quality cars will be exported to the UK. The United States and other developed countries, you have the money to buy the so-called original imported machines, in fact are not Japan's own production, are all other countries, and then to the joint vehicle that the quality can be thought of, this is the original vehicle and the difference between the Japanese used cars, but also why the second-hand car is the reason for the user's pursuit.
