尽管今年新机降价服务很大，但是挖掘机的新机价格依然是很贵的，就算一台小小的60挖机，也可以足以买辆奥迪轿车了。所以依然很多人在最初买挖机的时候，都会考虑二手的。但不是所有的二手挖掘机都能入手的，今天小编就给大家说说哪些二手挖掘机千万不能买。

　　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.

　　第一种：工作时间太长的不能买

　　The first type: cannot buy for long working hours

　　要知道虽说国内没有明确给出挖掘机的强制报废时间，理论上，在中国只要你想继续使用，挖机是可以一直做事的。但事实上，一般挖机的使用寿命时间在2万小时。所以，如果挖机上了一万多小时的话，就不建议大家购买了。并且，时间久了，挖机的废气也就很多。目前，国内由于环保的问题，已经有些地方不允许使用这类挖机了。在这里小编并没有提年限问题，因为年限并不能代表什么。一个挖机的好坏，主要还是看作业情况及工作时间。事实上，国外的一些进口机，年份虽说长，但工作时间真的不多。所以，进口的二手挖掘机之所以贵，最主要还是因为这一点。

　　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.

　　第二种：打过破碎的不能买

　　The second option: cannot buy items that have been broken

　　长期从事挖掘机行业的朋友，都应该知道破碎作业对挖掘机的液压方面伤害很大，会加速挖掘机的老化。可以这么说，一个挖机打1千个小时破碎，相当于其它方面干了3千个小时的活。所以，理论上来说，破碎机子寿命一般只有7千个小时。所以，大家在选购二手挖掘机的时候，看到破碎机还是远离吧。有些卖家会说，破碎只是装配，并没有打过或都没有打过多少。那么，这就要看你是否经验老道了，如果能判定好的话，那就多还点价格，值得入手。如果不能判断，抓紧走。

　　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.

　　第三种：冷门机型不能买

　　The third type: unpopular models cannot be purchased

　　目前国内的挖掘机品牌还是比较多的。但最常见的依然是小松、日立、卡特、沃尔沃、斗山、神钢等主流品牌。其实国内还有一些像竹内等稀有品牌。这类机，小编是不建议大家购买的。当然，这类机子的用户反映情况也是不错的。有些挖友就感觉到他们好，就特意找这类机型。事实上，这类机型，由于国内占有率太低，导致配件供应不上。所以，一旦挖机遇到问题，一般都很难解决。所以，如果当地没有人用这类机型，或者这类机型比较少，还是不建议购买。另外如果你遇到了奇瑞重工、五粮液普什重工这样的另类挖掘机，小编还是劝你一句，别买个“爷爷”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.

　　第四种：长期挖煤的不能买

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

　　至于这个是什么原因，小编并不知晓。估计是由于挖机在作业时，灰比较大，容易被发动机吸进去吧，加速发动机的衰老。之所以小编把它加上，是因为小编在从事二手挖掘机的销售中，一个资深老师傅告诉我的。

　　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.
