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.

3. It's supposed to be Hitachi. Hitachi's mine excavators are very famous.

4. www.bonnyhm.com Bangli heavy machinery is a leader in the manufacturing instry of large and extra large excavators in China. At present, it has proced the largest electric hydraulic excavator ced2200-7 in China
Bangli heavy machinery 46 ton electric hydraulic excavator is a good choice for you. It uses electric drive technology, does not consume a drop of diesel, saves energy, environmental protection and costs, Its operating cost is about half of that of diesel excavator

5. XCMG's is in line with your requirements. Their family has a xe4000c machine, which is the largest tonnage hydraulic excavator in China, and can meet the mine construction conditions. This model adopts Cummins full electronic control engine and two-stage turbocharging technology, which can work at an altitude of 3353m without power loss and improve fuel economy; LTA low temperature post cooling system is adopted to ensure the intake air temperature and engine cylinder life. Hope to adopt!

6. At present, the sales volume of domestic excavators is increasing rapidly. If you buy small excavators of less than 15 tons, you can buy domestic excavators, because the price is low, the maintenance cost is low, the failure rate is higher, and the comfort level is lower. As long as you can receive them, there is no problem< At present, medium and large excavators can not be made in China. One reason is that the failure rate of domestic excavators is relatively high, and the quality requirements of mines are very high (if dry earth can make do with it, the mines can't make do with it). There is also a rapid depreciation, two years after the sale is very worthless. The last one is that I think the price of Longgong is even higher than that of the Korean brand of mature procts. The cost performance is too poor
don't be fooled by Longgong's salesmen. The performance of excavators in the market is the absolute principle
for excavators of this level, it is recommended to buy Korean brands. If you buy Hyundai, Hyundai 225-7 or Hyundai 225-9, you should never buy 225-9t. Those who buy Doosan can only buy Doosan's 220-7
for 30 ton excavator, you can consider Carter, and for 40 ton excavator, consider Liebherr
as a professional, I know about excavators, but it's only for your reference.

The efficiency of Japanese excavators used in earth and rock works is relatively high

However, from the development trend of the engineering instry, the market of 20 ton excavator is getting smaller and smaller. If the project with relatively large quantity and long time needs to buy about 35 ton excavator, there will be more market

in addition, if the project may be in Northwest China, where the climate is dry and the st is heavy, the excavator will be equipped with another air filter. The effect is better

10. There are about three types of excavators, large, medium and small. The small ones are less than 10 tons, mainly engaged in ditch excavation, agricultural earthwork, foundation excavation, real estate infrastructure pile digging, etc. The medium-sized ones are more than 10 tons and less than 30 tons, which are suitable for river excavation, real estate earthwork excavation, mine crushing, etc. More than 30 tons are large excavators, mainly used in coal mines and other mining instries. The general leasing methods include monthly rent (the supplier provides excavators and drivers, and the tenant provides diesel), hourly rent (the excavator is rented by the hour, and all expenses are paid by the supplier), and workload charge (the amount of earthwork is paid). Excavator is a good investment direction, but the most important thing is to be able to receive the project. If you have a good interpersonal relationship and can receive the relatively long-term and stable project, it is not a problem to dect about 10000-20000 profit from the average monthly expenses (staff salary, oil, loan).
