Komatsu: Japanese brand, excavator instry leader, high cost performance, independent proction

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 is easy to sell

Disadvantages: high price and expensive accessories Note: because of its high domestic share and many accessory parts, it is also relatively cheap)

20t model: reference price pc200-897-100wpc200-8 hybrid (preferred for earthwork, fuel consumption is 30% less than ordinary cars) 110-118w

Hitachi: Japanese brand, excavator sales volume is also large, overall also OK, assembly

advantages: the mechanical matching is general, the hydraulic system is general, the action is flexible, generally rable, 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's not rable, there are many problems after two or three years, and there are serious oil leaks, mainly e to high water temperature or hydraulic system. At present, No.20 machine is replaced with four lack engines, but it's to increase the lack of strength and rece the displacement, so it's not dare to use, and the price of second-hand car is average

20t zx200-3g reference price 95-98w

Shengang: Japanese brand, large sales volume, generally OK, assembly

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

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

20t ec210b reference price 100-106w

Doosan: Korean brand, comprehensive moderate, imported aircraft is low-grade procts, assembly

advantages: low price, - 8 series low fuel consumption. 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

20t dh215-9 reference price 80-85wdh225-986-91w

Hyundai: Korean brand, but it is really low-end goods, assembly

advantages: the price is cheaper, the parts are easy to buy and cheaper

Disadvantages: the machine can't even reach the level of domestic machine

personal point of view: imported brands can only buy the above brands. Case, Kato, Terex, libaoer, Sumitomo and ishikawashima are not allowed to buy. They have low share, few after-sales service points and difficult parts. If you buy them, there will always be these problems

Komatsu and Carter belong to independent proction brands, and the first consideration is that the comprehensive capacity of domestic machinery below

is much lower than that of imported brands. But it's still graded

First: Sany Heavy Instry, JCM, Liugong, Shanhe intelligent, Yuchai

the second level: XCMG, Zoomlion, xudiao, Longgong, Lingong, ward, Shantui, lishde

finally: Zhan Yang, Zhenyu, rhinoceros, Changlin, Kaiyuan

The final assembly of the excavator went off the proction line today and was delivered to China Coal Group Pingshuo Company. This marks that Taizhong group has stepped into the ranks of the largest mining excavator manufacturing company in the world and become one of the three largest excavator manufacturers in the world. Taiyuan Heavy Instry: the huge mining excavator has been certified to fill the gap in China. Each wk-55 large mining excavator is 22 meters high, equivalent to the height of 8-story building, with a total weight of 1400 tons, equivalent to the total weight of 70 trains. Its bucket capacity is 56 cubic meters, and its annual output can reach 12 million cubic meters, that is to say, the monthly excavation volume can reach more than 1 million cubic meters. It is not only the largest excavator in China, but also the largest excavator in the world. The successful offline of the equipment makes the key equipment in the complete set of equipment for large open pit mines above 20 million tons no longer rely on imports, breaking the long-term monopoly of foreign giants. It took only six months from February 2007 to the end of July 2007 when the design of the 55m3 excavator was completed. The successful development of wk series large excavators by Taizhong group indicates that Taizhong group has become the most advanced mining excavator development base in China and has entered the ranks of the largest mining excavator manufacturing company in the world. As the first listed company in China's heavy machinery instry, Taiyuan Heavy Instry Co., Ltd. manufactured wk-55, the world's largest mining excavator in 2008. After more than one year's open-air use in Pingshuo mining area of Sino US energy, all performance indicators have met the technical requirements, and successfully completed the cooperative relationship with China coal group. Through the appraisal of the Ministry of science and technology, this machine has filled the domestic blank and has been officially listed in the national key new proct plan. Duan Jiaxuan, chief researcher of CIC consulting machinery instry, believes that the wk-55 giant mining excavator of Taiyuan Heavy Instry Co., Ltd. has passed the test of practice, has carried out reliable certification on the quality and performance of the proct, and has been recognized by users. It has the ability to be widely used in related fields at home and abroad, thus ending the history of foreign monopoly of large mining excavators with more than 20 million tons in China. Large scale open-pit mine equipment is a national major technical equipment that needs to be localized, and it is also a key field of equipment manufacturing instry revitalization. The current situation in China is that more than 80% of the excavator market is controlled by foreign capital, and only small and medium excavators can be proced in small batch. There is a strong market demand for high-end mining equipment in the market. The equipment is the key equipment in the complete set of equipment for large-scale open-pit mines of more than 20 million tons in China, which can meet the mining conditions of all open-pit mines in the world. Taiyuan Heavy Instry wk-55 mining excavator has its own good performance, which is also the reason for market recognition. From the perspective of excavator terminal, the daily unit output of wk-55 excavator is higher than that of foreign equipment, but the price is only 70% of that of foreign equipment, which has good performance price ratio. While increasing the proction capacity, the equipment price is more economical. The localization of large excavators further shortens the interruption time in work and improves the efficiency of enterprises. Because mining machinery is in a high-intensity working environment, many procts adopt the way of people not stopping the machine and taking turns to shift, pay attention to timeliness, and create more economic benefits in the short term. When there is a problem with high-intensity work and accessories, the supply period of foreign accessories from proction to manufacturing is long and the price is expensive, which often affects the normal business activities of enterprises. On the contrary, domestic enterprises have convenient contact, short delivery time and perfect after-sales service, which saves the cost of customers. According to the investment analysis and prospect forecast report of China Construction Machinery Instry 2009-2012 released by CIC consultants, China's excavator instry has become the fastest growing model in China's construction machinery instry. In 2008, China's excavator sales reached 77173 units, an increase of 16.04%. However, 80% of the middle-class sales in the instry are occupied by foreign investors such as Japan, South Korea and the United States, and there is a huge room for the market share of domestic mining equipment to rise.

7. No, it's not tonnage, it's not technology. Excavators are multi-purpose, there's no strict distinction, but different devices are installed when the work is different, such as crushing in stone mine, bucket with good wear resistance in iron mine, and so on. Of course, for open-pit mines, large excavators are selected, as you said, more than 60 tons, in order to save cost and improve efficiency.

8. The mine must use machinery. Without machinery, can it be moved by manpower
as for which excavator or loader is used more, go and investigate the mine by yourself! Excavator is mainly digging, loader is mainly loading.

9. Bucket wheel excavator for open pit coal mine. As for brand, it depends on personal preference
bucket wheel excavator is an important equipment to complete the mining work in the continuous mining process of mining, transportation and drainage. It is used in large-scale projects with large mining volume and long service life, especially suitable for open-pit mine, large-scale earthwork and other applications
