Wu Xiaobo Channel
Which excavator technology is stronger?
The answer is not a technical school in Shandong, but China.
After more than ten years of tempering, China's excavator manufacturing has achieved "changing life against the sky".
Back in 2008, China's real estate ushered in a golden age, and the demand for excavators was strong. However, the related technology is "stuck" by foreign countries, and the excavator is heavily dependent on external imports. In 2010, the number of imported excavators reached 41,766 units, which was 8.08 times the export volume of that year. International manufacturers represented by European, American and Japanese OEMs such as Caterpillar and Komatsu have a market share of nearly 70%.
In 2020, the market share of domestic excavators reached 72%. Among them, the market share of leading enterprises represented by Sany Heavy Industry has increased from 7% in 2009 to 30% in 2021.
The Sany Heavy Industry factory is full of excavators
Today, the excavators produced in China are not only self-sufficient, but also exported overseas.
Since 2018, the export sales of excavators have maintained a significant growth trend. According to data from the China Construction Machinery Industry Association, in 2021, a total of 342,800 excavators were sold.Among them, 68,400 units were exported, a year-on-year increase of 97%.
The manufacturing level of excavators has advanced by leaps and bounds, and it is also favored by the public eye.In the past, whenever an excavator appeared on the construction site, it was always surrounded by people. Today, the people are still there, but they have moved from the construction site to their mobile phones.
There is an account called @excavator teaching Lao Luo, who teaches more than one million fans how to drive an excavator in a short video. From inserting the key and starting, to skillfully moving the big arm and small arm, and operating the bucket, novice Xiaobai can quickly learn how to shovel and put soil. In the event of a soil collapse or a broken track, there is also advanced teaching.
The excavator is so mysterious and charming, the minibus can't help but wonder, what has the excavator industry experienced in the past ten years? What has changed in the excavator itself? Today, the minibus will talk about thisExcavator Index: Micro Interpretation of the Economy of a Large Country,Let's find out.
Excavator Index: Barometer of the National Economy
In addition to bulldozing and shoveling, excavators also have unexpected uses.
The excavator is equipped with on-board controllers, sensors and wireless communication modules, and with the help of big data and Internet of Things technology, every time the excavator swings a shovel and takes a step, a piece of data will be formed.
With these data, it is clear at a glance which regions in China are under construction and what stage the construction period is overall. This is where the Excavator Index comes in.
What is the Excavator Index used for? Let's take a simple example of a minibus.
To build a building, you must first dig a pit to lay the foundation, then lay the pillars and beams, and build it layer by layer. Corresponding to the three main equipment, the order of appearance is roughly: excavator - mixer truck - tower crane.
The excavator is the main force of digging the ground, as the "first spade to start the ground", it must be in place at the earliest; The concrete pouring of the foundation requires a large amount of cement, and the mixer truck follows closely; If the building is a little higher, the tower crane will come in handy for high-altitude work.
According to this classification, when a project is still in the stage of using a large number of excavators, it means that the project is still in the first stage of "starting and breaking ground". When various tower cranes start to work at height, the project is likely to be in the middle and late stages.
The excavator index shows that in the whole year of 2021,Truck cranes, excavators and pump trucks are among the top three in terms of operating rates. Among them, the cumulative workload of truck cranes increased by 12.8% year-on-year, ranking first among all equipment.It shows that the national construction period is in the second and third stages as a whole.
The "most" critical data
(1) The "most" provinceHubei is strong, Hainan is busy
In 2021, Hubei Province was one of the brightest performing provinces. The cumulative average workload growth of excavators and truck cranes ranked first in the country. In addition, the cumulative average workload of pump trucks, pavers and forklifts in Hubei ranked first in the country in terms of year-on-year growth. These dazzling figures show the strong resilience of Hubei's economy.
Hainan Province is also worth mentioning. In 2021, seven pieces of equipment in Hainan Province, including crawler cranes, pump trucks, truck-mounted pumps, mixer trucks, mixing plants, reach stackers, and road rollers, will enter the "National TOP10" list with a year-on-year increase in cumulative average workload.
(2) The "most" of the cityChongqing repairs the bridge, and Beijing is busy with the Winter Olympics
In 2021, Chongqing's infrastructure construction made great strides forward and ran out of the "Chongqing speed".
In particular, the "three bridges and one tunnel" - Water and Soil Bridge, Caijia Bridge, Lijia Bridge, and Tuzhu Zhongliangshan Tunnel were announced to be completed and opened to traffic three months ahead of schedule. The excavator index shows that the cumulative workload of crawler cranes and truck cranes in the later stage of the project has increased by 88% and 72% year-on-year.
If Chongqing is running in great strides, Beijing is moving steadily and slowly.
Beijing is China's first double Olympic city (Summer Olympics + Winter Olympics). Throughout last year, Beijing was busy preparing for the Winter Olympics, and the operating rate of trailer pumps, concrete mixing plants, truck cranes, pump trucks and other equipment in the city increased significantly.

(3) The "most" of the provincial capitalHeavy rain in Zhengzhou, excavator rescues
In late July 2021, a flood occurred in Zhengzhou, Henan Province. This rainstorm opened up a "new idea" for excavators.
Sany Group launched an emergency cloud platform based on the Tree Root Interconnection Industrial Internet Platform, and dispatched machinery and equipment in Henan Province to provide equipment support for the prevention and control of flash floods and geological disasters, urban waterlogging, and reservoir and river floods caused by continuous precipitation.
Excavators have become the main force in the local excavation of drainage canals and the construction of flood control levees.In the section of the road where the water is seriously waterlogged, the excavator transfers the trapped people. The excavator index shows that the operating rate of excavators in Henan Province has always remained at a high level of about 70% in August 2021.

In addition, there are many highlights in the report. For example, in 2021, the "pioneers" are Hubei Province and Anhui Province. In the past two years, excavators accounted for 29% of the rural market, and the sinking market will become a new variable in the construction machinery market in the next 3-5 years.
From data to big data: the Industrial Internet is in the ascendant
At present, the excavator index has become a "national" index brand, which is an attempt made by a company called Tree Root Internet.
The company installed sensors on various construction machines sold by Sany to collect and analyze data. Today, the Excavator Index is a compilation of data from more than 700,000 devices.
Data is a digital expression of the Industrial Internet.
In addition to monitoring industry dynamics, data can also provide early warnings. If the system finds that the operation data of a large piece of equipment is abnormal, it can "cloud diagnosis" online and arrange maintenance personnel to check it as soon as possible, so as to avoid the shutdown of the entire machine due to the failure of a small part.
There are many such examples, and the root cloud platform, as an industrial Internet operating system focused on building by Tree Root Internet, provides technical support for device connection, data modeling and analysis. Up to now, the root cloud platform has connected more than 900,000 high-value industrial equipment, covering 48 industrial sub-sectors such as equipment manufacturing, parts, and steel, and serving 112 countries and regions.

presentlyThe Industrial Internet has entered deep waters.On December 20, 2021, the National Conference on Industry and Informatization proposed to implement the action plan for the digital transformation of the manufacturing industry, improve the multi-level industrial Internet platform system, break through a number of intelligent components and equipment, and expand the application scenarios of industrial big data.
In the future, the industrial Internet platform represented by tree root interconnection will truly become the "data base" made by a big country.Help more industrial enterprises achieve digital transformation and promote the upgrading of the industrial chain.
