Which excavator technology is strong?？If the answer points to a city in the country，There must be.“Capital of Construction Machinery”The title of Changsha, Hunan，The No.18 factory of Sany Heavy Industry, which was awarded the Lighthouse Factory in 2022, is located here.。Plant 18 of Sany Heavy Industry，Yangcheng Evening News and Changsha Evening News jointly go deep into the front line of industry，Explore its construction of a new quality of productivity“The secret book”。

Factory“Rigidity with softness”

A pump truck can be offline every 45 minutes.

Intelligent Transformation of Chaonaoliang Coal Mine

Big，It is the first impression of many people when they enter the No.18 factory of Sany Heavy Industry.——Not only is the production area large here,，It takes a long time to walk through it.，At the same time, there are many heavy components and large-scale production equipment.，The products off the production line are also huge in size.，The longest boom can reach 86 meters.。

Having a long boom“Big guy”

These have long booms.“Big guy”Products，It is called a pump truck，It is the concrete pumping equipment used by workers when building high-rise buildings to pump concrete.。Here，A plain steel plate has been cut.、Cut、Welding、Whole process intelligent production of assembly, etc.，Finally, it can produce pump trucks with different models and specifications.，It gives people the impression that it is both tough and watertight.。

“Big guy”

Use a set of data to show the effect of intelligent transformation of No.18 factory.：A pump truck can be offline every 45 minutes.，Annual output of nearly 10,000 sets；The whole production cycle from steel plate to pump truck has also been greatly shortened.，From 31 days before the renovation to 12 days after the renovation.7 days；The manufacturing cost of a single pump truck is reduced by 29 percent%，Overall personnel efficiency increased by 98 percent%。

In addition to giving people a strong impression.，Factory 18 is not“Stuffy”，Capable of very flexible and flexible production。

“Why is it difficult for the construction machinery industry to develop intelligent manufacturing?，The reason is that we are a typical discrete production mode.，Be called‘Tailor of steel’，It is also the production of many varieties and small batches.，Production ranges from a few hundred to several thousand units.，The core is how to break through flexibility.”， Liu Xiangju, responsible person of Sany Heavy Industry Pump Road Business Department, told reporters.。

Specific to the landing of flexible production，Liu Xiangju used it“The devil is in the details.”To describe this process.，For example, he said，In unmanned butt welding，Weighing 2.For the 6-ton pump truck turntable, the two parts shall be aligned before welding.，It was originally thought that it could be easily solved by robot vision technology.，But because the precision requirement of the product is 0..Within 1 mm，General technology can not reach，It took them more than a month to overcome a series of technical difficulties.。

After intelligent transformation，The No.18 factory can realize mixed production.，The two assembly lines can carry out flexible production of 69 kinds of products.。

In 2022, it was rated“Lighthouse factory”Plant 18 of Sany Heavy Industry

Digital Response to Cyclical Fluctuations

1989，Liang Wengen、Tang Xiuguo、yuan Jinhua、Mao Zhongwu took the scraped together 60,000 yuan.，A workshop-style factory was built in an abandoned farm in Daotong Village, Maotang Township, Lianyuan, Hunan Province.——Lianyuan Maotang Welding Material Factory。Insufficient funds，They built the factory by themselves.，Weld the roof truss、Painting equipment、Install the equipment、Handling of materials……

1991，The company officially changed its name to Sany Group.，And entered Changsha, Hunan in 1994.，Advance into the field of equipment manufacturing，By 2011, it will grow into one of the top 500 enterprises in the world.。However，2011 to 2016，With the global construction machinery industry cooling down for five consecutive years,，Sany Group also began to feel an unprecedented sense of crisis.。To meet the challenge，2018，Liang Wengen, founder of Sany Heavy Industry, once said a word at the two sessions.，“The digitization of Trinity，If you don't turn over, the boat will capsize.”。

Road machinery

Early 2019，Factory No.18 was the first to start the construction of the lighthouse factory.。“At that time, there was no case of digital transformation in the construction machinery industry.，And the lighthouse factory is to reflect the leading role.”，Liu Xiangju introduced，Before the transformation，The factory adopts a single-point automatic production mode.，Devices are isolated from each other。To this，Sany Heavy Industry has overcome thousands of difficult problems.，11 industry-first technologies and 59 key technologies were used to transform the plant.。2022，Factory No.18 became the Beijing Pile Machine Factory of Sany Heavy Industry.，The second certified lighthouse plant in the global heavy industry。

In the construction of the lighthouse factory，The industrial Internet platform created by tree root interconnection plays a key role.。

Statistics show that，Plant No.18 of Sany Heavy Industry can produce more than 30 per dayTBBig data，It is equivalent to the mobile phone network traffic generated by a county with a population of 200000 in one day.。Qi Ting, a consulting expert on digital transformation of tree root interconnection who has long served Sany Heavy Industries, said.，The amount of data depends primarily on two factors，First, the number of fields collected，The second is the collection frequency.，There is so much data generated.，It also shows that the demand for data in the business of Factory 18 is indeed very large.。

Sany Heavy Industry No.18 Factory

Inside“Digitize，It is nothing more than letting the mass production equipment of the factory learn.‘Talk’，And understand the instructions.”，Qi Ting summarized this process as follows:“Three-current and four-meter interconnection”，That is, to manage the scene through the camera、Reality、Present things，Collect water、Electricity、Qi、Fuel gauge and other energy consumption data，“Interconnection”It is around the above three scenes.，Will“Four tables”The management moved to“Root Cloud Platform”，Make factory operations transparent everywhere。At present，Sany Group has more than 1.80 thousand operation equipment are networked.。

It is built by relying on the interconnection of tree roots.“Transparent factory”，Combining digital twins、Big data、AIAnd other technologies，Factory 18 just came true.“From hardness to softness”，Better response to cyclical fluctuations in the heavy industry market。

Settled in Changsha for 30 years

　　“Lighthouse”More than 130,000 experience-enabling enterprises

This year，Distance from Sany Heavy Industry to go out of mountainous areas and settle in big cities，Exactly 30 years have passed.。At present，Changsha, Hunan Province, has become the third largest construction machinery industry cluster in the world after Illinois in the United States and Tokyo in Japan.，Total assets of construction machinery industry、The proportion of business income and profit is in the forefront of the country.，Gathered Zoomlion、Railway Construction Heavy Industry、A large number of well-known construction machinery enterprises such as Sunward Intelligence。

In 2022, it was rated“Lighthouse factory”The digital screen of Sany Heavy Industry No.18 Factory

Settlement and Development of Sany Heavy Industry in Changsha，It has also led to the agglomeration and coordinated development of the surrounding related industrial chains.。

Take hydraulic parts, one of the key basic parts of construction machinery, as an example.，2021，Shanghai Norma Hydraulic System Co., Ltd. signed a contract with Changsha Economic Development Zone，Provided for Changsha construction machinery main engine enterprises“Service at home”；2023，Shenzhen Sante Hydraulic Technology Co., Ltd. moved to Changsha as a whole，158 employees of the former Shenzhen factory also moved to Changsha.。
