It is recommended that Komatsu pc360-7, Dourong 1.6 square rock, and the price is about 170-173w. You can get to know it on the spot. Now most of Ordos and Shenhua mines in Inner Mongolia are equipped with this car. In addition, Shenhua has several 1250

let's talk about the joint venture brand

caterpillar: American brand, old brand, independent proction

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

20t model: reference price cat320dgc97-100w320d110-115w

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

20t model 210lc-8 (super8) reference price 97-102w

Volvo: good brand, big sales, good reputation, overall good, assembly

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

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.

Terex rh400 excavator is the largest excavator in the world. There are six excavators in the world. The first one was manufactured in 1997, and the improved sixth one was launched in 2002. Among them, the fifth one is electric driven. The diesel engine version uses two Cummins qsk60-c diesel engines (16 cylinders, turbocharged) with a tank capacity of 16000 L. five of the six excavators are in the United States One is used in a Canadian mine, with a total weight of 1008 tons, a maximum power of 4398 horsepower and a bucket capacity of 43.58 cubic meters

extended data:

excavator, also known as excavation machinery, also known as excavator, is a kind of earth moving machinery that uses bucket to excavate materials higher or lower than the bearing surface, and load them into transport vehicles or unload them to the stockyard

the materials excavated by excavators are mainly soil, coal, silt and soil and rock after pre loosening. From the development of construction machinery in recent years, the development of excavator is relatively fast, excavator has become one of the most important construction machinery in engineering construction. The three most important parameters of excavator are operating weight (mass), engine power and bucket capacity

8. The literal meaning is the difference, that is, the difference between big and small
dh60-7 belongs to Doosan, 6T (6T, not explained below), which is small. Generally, the level below 20t is small. 20t-35t is medium-sized, and 35t and above are large-scale
the current operation standards in the world are left forearm and forearm movements, left and right rotation movements; The front and rear arms of the right hand move, and the left and right buckets move. Therefore, no matter whether you use big dig or small dig, the operation is the same
of course, the original two mobile phones imported more than ten or twenty years ago were left-hand side turning back and forth, left and right forearms, and other movements were the same. Some teachers need to change the handle to adapt
to be honest, as long as you can drive one, it's very easy to drive another. Just adapt to it for a few minutes. But there are several points to pay attention to, small dig up and down flat to pay attention to safety, too small easy to turn over; Pay attention to the surrounding environment in large excavation. If it is too large, the line of sight is limited and it is easy to collide.

The biggest model of excavator is tz-22. It is the largest bucket excavator in the world. It is proced by China's Taizhong group. The equipment is 22 meters high, which is equivalent to the height of an 8-story building. Its total weight is 1400 tons, which is equivalent to the total weight of 70 railway cars. Its bucket capacity is 56 cubic meters. It is not only the largest in China, but also the largest in the world, which can meet the mining conditions of all open-pit mines in the world

At present, several major domestic second-hand excavator sales platforms will divide the size of the machine, in which small excavators are divided into micro and small excavators. Basically, micro excavators are below 5 tons, while small excavators are defined as models between 5 and 15 tons

1 and below 15 tons are small, and 5 to 8 tons are the mainstream. Small excavators are mainly used in municipal, trenching, plant construction, garden and other conditions that need careful operation

2, 15 to 35 tons are medium-sized, and 20 to 25 tons are the mainstream models, which are also the most widely used of all models. It can be used in almost all working conditions, such as municipal administration, earthwork, road construction, mining, land reclamation, etc., except that the site is limited (such as indoor)

3, more than 35 tons are large. The bigger the tonnage, the bigger the bucket. Generally used in large-scale earthwork and open-pit mining conditions

Second, there is no unified standard for excavator size division in other countries. Here, we have sorted out the excavator size division standards of representative brands in the United States, South Korea and Japan for comparison and understanding

1. Caterpillar is a brand in the United States, and its size is classified into five categories: mini excavators of less than 10 tons, small excavators of 11-19 tons, medium excavators of 20-35 tons, large excavators of 36-90 tons, and mining hydraulic excavators of more than 100 tons

There are only three kinds of excavators in Korea: small excavators less than 6 tons, medium excavators less than 8-40 tons and large excavators more than 40 tons

3, Hitachi construction machinery

the size of Hitachi excavators can be divided into four categories: mini excavators of less than 6 tons, small excavators of 7-12 tons, medium excavators of 17-40 tons and large excavators of 40-100 tons
