1. There may be combustible and explosive gas in the environment where the excavator is used.
the engine and circuit of the excavator are treated to prevent high temperature and electric spark. To achieve explosion-proof effect.

2. Don't buy Carter. It's too fuel consuming. If you can afford it, you can buy the original Liebherr excavator. This car is the best choice. Or you can choose Komatsu. Don't think about anything else
3. The following basically covers the existing mainstream brands
let's start with the joint venture brand
caterpillar: American brand, old brand, independent proction Cat)
advantages: sufficient strength, rable, strong, not easy to break
disadvantages: high price, high fuel consumption, short arm and small working range. Especially for the mine type, the fuel consumption is high and the after-sales service is average
Komatsu: Japanese brand, excavator instry leader, total cost-effective, independent proction Komatsu)
advantages: good strength, strong, rable, low fuel consumption, hydraulic is its strength, good overall coordination, fast speed, not easy to break, good value preservation, second-hand car easy to sell
disadvantages: high price and expensive accessories Note: because of its high domestic market share and a large number of accessory parts, it is also relatively cheap)
Hitachi: Japanese brand, excavator sales volume is also very large, overall also OK, assembly Hitach)
advantages: the mechanical matching is general, the hydraulic system is general, the action is flexible, the general rability, the value preservation is general, the use cost is general, the fuel consumption is general, the strength is medium, and the price is about 30000-50000 cheaper than Komatsu
disadvantages: it is not rable, there are many problems after two or three years, and there is a serious oil leakage, mainly e to the high water temperature or the hydraulic system. At present, the No.20 engine is replaced by the No.4 engine, but it is to increase the lack of strength and rece the displacement, so it is not dare to use, and the price of second-hand cars is average<
Shengang: Japanese brand, large sales volume, generally OK, assembly Kobelco)
advantages; Low down payment and fuel saving. The color is good
disadvantages; It's not strong and rable. After a major overhaul of the four cylinder engine, the quality is very poor. It can only do earth work. Because there is no strength, the things pieced together are certainly not easy to use
Volvo: good brand, big sales volume, good reputation, overall good, easy to assemble Volvo)
advantages: good safety and luxury. Fuel saving, fast
disadvantages: Volvo's new machine is OK, but the localization is serious, fragile and not thick enough. The price of the second mobile phone is low, so it's hard to sell
Doosan: Korean brand, comprehensive more moderate, imported aircraft is low-grade procts, assembly Doosan)
advantages: low price and low fuel consumption of - 8 series. It can be used in all kinds of projects
disadvantages: low price brings inferior proct quality, moderate price, moderate quality and poor after-sales. The degree of hedging is low
the reference price of 20t dh215-9 is 80-85w, dh225-9 86-91w
Hyundai: Korean brand, but it's really low-end goods, assembly Hyundai)
advantages: cheaper price, easy to buy accessories, cheap
disadvantages: the machine can't even reach the level of domestic machine, so it's good or bad
personal point of view: imported brands can only buy the above brands, case, JCB, Kato, Terex, liebher, Sumitomo, IHI, kubato, Takeuchi are not allowed to buy, the share is low, there are few after-sales service points, it is difficult to buy accessories, if you buy, There are always these problems<
Komatsu and Carter belong to independent proction brands, and the first consideration is that the comprehensive capacity of the following domestic machines is much lower than that of imported brands. But it's still graded The first file: Sany Heavy Instry, JCM, Liugong, Shanhe intelligent, Yuchai
the second level: XCMG, Zoomlion, xudiao, Longgong, Lingong, ward, Shantui, lishide
finally: Zhan Yang, Zhenyu, rhinoceros, Changlin, Kaiyuan

4. The largest excavator in the world has 1400 tons and the bucket has 56 cubic meters, which is used in Taiyuan mining heavy instry
5. About 20 million for 35, more than 4000 for 55, I'm the one from that unit
6. The difference between the mining version and the ordinary version of the excavator is that the thickness and strength of the steel plate of the big frame are the same. The hydraulic pump and engine of the excavator with the same configuration are the same, but the tuning power is slightly different. The mining version is more resistant to operation, and the ordinary version is suitable for excavation and infrastructure construction. A typical mine excavator is Carter
7. Shaanxi Pinjia is more reliable. The performance of the excavator is comparable to that of the imported one, but the price is much cheaper than that of the imported one.
8. In fact, it's very good to buy Shaanxi Pinjia, but the price is lower than the imported one, and the function is no inferior to the imported one.
9. In the newly adjusted catalogue, excavators are no longer special equipment
10. Brother, choose domestic excavator. The quality of Lovol excavator is very good, which is not inferior to that of imported excavator. Its cost performance is high. Also, it consumes less fuel and can save a lot of money every day. I suggest you refer to it.
