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. 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

4. If it's pure earth, no rock, then 1-3 cubic meters of hook machine can be, the key depends on what car you match, to match with the car. If it's a level road, it's estimated that someone will do it at 10 yuan per square meter. If it's a bad road, it depends on the specific situation; It also depends on the convenience of your mp, oil supply, payment, and so on. There are many problems to pay attention to, but there are two things to sum up: first, safety first, no casualties and major accidents; Second, don't be reckless. You have to earn money.

5. More than 360 must be reinforced two arm

6. If the construction is carried out in the river, the silt is relatively soft and deep. It is better to use the excavator with less self weight. Generally, 20t is enough. The crawler must be widened, and the width of the crawler shoe is more than 800mm. If not, it is better to pad a steel plate as big as the whole machine under the crawler, and the thickness of the steel plate is about 10mm, so as to prevent the excavator from falling into the silt. In short, we should pay attention to safety.

7. Catamaran land and water excavators, such as Hubei xingyong machinery land and water excavators

8. The skill is to dig faster by contract work and slower by spot work

9. Yes, the land and water excavators of Hubei xingyong Machinery Manufacturing Co., Ltd. are mainly used for river dredging.

10. The proct is widely and efficiently used in water conservancy projects, river and lake dredging in urban and rural construction, resource development of wetland and tidal flat, and environmental remediation excavation. The proct is a multi-purpose excavator suitable for land, swamp and shallow water working environment. The traveling device adopts multi hull pontoon structure and sealed box crawler plate, which can safely walk and work in mud and water. The strengthened super long working arm and efficient rotary mechanism ensure the operation quality and excavation efficiency. The spacious driving space and the concise photoacoustic audio-visual warning system improve the convenience and comfort of operation. The scientific and reasonable matching of advanced hydraulic system and power system device can easily realize compound operation and ensure the unity of high efficiency and high economy. Although the proct can be used for amphibious excavation, its working capacity and efficiency are not as good as land excavators. When the water depth is more than 1.0 meters, the manufacturer needs to carry out technical treatment and special customization on the structure. At present, there are few large-scale manufacturing enterprises in China. Hefei Shuntong machinery is an early professional enterprise in R & D and large-scale proction of such procts. Foreign countries such as Germany and Japan also have similar proct manufacturers. More picture books
