盡管今年新機降價服務很大，但是挖掘機的新機價格依然是很貴的，就算一臺小小的60挖機，也可以足以買輛奧迪轎車了。所以依然很多人在最初買挖機的時候，都會考慮二手的。但不是所有的二手挖掘機都能入手的，今天小編就給大家說說哪些二手挖掘機千萬不能買。

　　Although the price reduction service for new excavators is significant this year, the price of new excavators is still very expensive. Even a small 60 excavator can be enough to buy an Audi sedan. So many people still consider second-hand excavators when they first buy them. But not all second-hand excavators can be purchased. Today, Xiaoma Ge will tell you which second-hand excavators should not be bought.

　　第一種：工作時間太長的不能買

　　The first type: cannot buy for long working hours

　　要知道雖說國內沒有明確給出挖掘機的強制報廢時間，理論上，在中國只要你想繼續使用，挖機是可以一直做事的。但事實上，一般挖機的使用壽命時間在2萬小時。所以，如果挖機上了一萬多小時的話，就不建議大家購買了。并且，時間久了，挖機的廢氣也就很多。目前，國內由于環保的問題，已經有些地方不允許使用這類挖機了。在這里小編并沒有提年限問題，因為年限并不能代表什么。一個挖機的好壞，主要還是看作業情況及工作時間。事實上，國外的一些進口機，年份雖說長，但工作時間真的不多。所以，進口的二手挖掘機之所以貴，最主要還是因為這一點。

　　You should know that although there is no clear mandatory scrapping time for excavators in China, theoretically, as long as you want to continue using them, excavators can continue to work in China. But in fact, the service life of a general excavator is 20000 hours. So, if the excavator has been on for over 10000 hours, it is not recommended for everyone to purchase it. And over time, the exhaust gas from the excavator will also be a lot. At present, due to environmental protection issues, some places in China no longer allow the use of such excavators. The editor did not mention the issue of years here, as years do not represent anything. The quality of an excavator mainly depends on its performance and working hours. In fact, some imported machines from abroad, although old, do not have many working hours. So, the main reason why imported second-hand excavators are expensive is because of this.

　　第二種：打過破碎的不能買

　　The second option: cannot buy items that have been broken

　　長期從事挖掘機行業的朋友，都應該知道破碎作業對挖掘機的液壓方面傷害很大，會加速挖掘機的老化。可以這么說，一個挖機打1千個小時破碎，相當于其它方面干了3千個小時的活。所以，理論上來說，破碎機子壽命一般只有7千個小時。所以，大家在選購二手挖掘機的時候，看到破碎機還是遠離吧。有些賣家會說，破碎只是裝配，并沒有打過或都沒有打過多少。那么，這就要看你是否經驗老道了，如果能判定好的話，那就多還點價格，值得入手。如果不能判斷，抓緊走。

　　Friends who have been engaged in the excavator industry for a long time should know that crushing operations can cause significant damage to the hydraulic system of excavators and accelerate their aging. It can be said that one excavator can crush for 1000 hours, which is equivalent to doing 3000 hours of work in other aspects. So, theoretically speaking, the lifespan of a crusher is generally only 7000 hours. So, when purchasing second-hand excavators, it's better to stay away from crushers. Some sellers may say that the breakage is just an assembly and has not been hit or has not been hit much at all. So, it depends on whether you are experienced or not. If you can make a good judgment, then you should pay more for it. It's worth buying. If you can't make a judgment, hurry up and leave.

　　第三種：冷門機型不能買

　　The third type: unpopular models cannot be purchased

　　目前國內的挖掘機品牌還是比較多的。但最常見的依然是小松、日立、卡特、沃爾沃、斗山、神鋼等主流品牌。其實國內還有一些像竹內等稀有品牌。這類機，小編是不建議大家購買的。當然，這類機子的用戶反映情況也是不錯的。有些挖友就感覺到他們好，就特意找這類機型。事實上，這類機型，由于國內占有率太低，導致配件供應不上。所以，一旦挖機遇到問題，一般都很難解決。所以，如果當地沒有人用這類機型，或者這類機型比較少，還是不建議購買。另外如果你遇到了奇瑞重工、五糧液普什重工這樣的另類挖掘機，小編還是勸你一句，別買個“爺爺”回家。

　　At present, there are still quite a few excavator brands in China. But the most common ones are still mainstream brands such as Komatsu, Hitachi, Caterpillar, Volvo, Doosan, and Jingang. In fact, there are some rare brands in China such as Zhunei. I do not recommend purchasing this type of machine. Of course, the feedback from users of this type of machine is also good. Some digging friends feel that they are good, so they specifically look for this type of model. In fact, due to the low domestic market share, these models are unable to supply accessories. So, once the excavator encounters a problem, it is usually difficult to solve. So, if no one in the local area uses this type of model, or if there are relatively few such models, it is still not recommended to purchase. In addition, if you encounter alternative excavators such as Chery Heavy Industry and Wuliangye Pushi Heavy Industry, I still advise you not to buy a "grandpa" to go home.

　　第四種：長期挖煤的不能買

　　The fourth type: Those who dig coal for a long time cannot buy it

　　至于這個是什么原因，小編并不知曉。估計是由于挖機在作業時，灰比較大，容易被發動機吸進去吧，加速發動機的衰老。之所以小編把它加上，是因為小編在從事二手挖掘機的銷售中，一個資深老師傅告訴我的。

　　As for the reason behind this, the editor is not aware. Probably due to the large amount of ash in the excavator during operation, it is easy for the engine to suck it in, accelerating the aging of the engine. The reason why I added it is because I was told by a senior master in the sales of second-hand excavators.
