Making cranes like this.“Steel behemoth”He can also lift weights lightly、Rigidity with softness？The secret of Sany Restart is to promote the transformation of digital intelligence in depth.，Leading the industry in a new direction。Under the condition of high digital intelligence，Not only has labor productivity nearly doubled.，The production cycle has also been significantly reduced to a daily basis.，Let Sany restart more steadily and powerfully in the global market.。

From“The first one in China”To“The world's first”，The Development Course of Sany Restart，Witnessed China's construction machinery industry from the market、Counterattack in all aspects of technology、Leading the world's advanced level，Become a dazzling star of the East。

Lift weights lightly

Walk into the Sanyi Heavy Lift Welding Workshop in Ningxiang City, Hunan Province，Six huge work stations for welding the frame are lined up.，Extend hundreds of meters in depth。Ten in the morning，It is the peak time of production.，But in this welding workshop,，There are only one or two workers at each workbench.。Every workbench，Two large welding robots are suspended from a truss several meters high.，Pulling two welding wires.，It's nearly 10 meters long.、More than 2 meters wide、The huge frame weighing several tons is busy efficiently.。

Weld sparkle flashes，Manipulator dance，After a series of highly automated production processes,，A crane with a load of 50 tons within 14 days，It can complete the magnificent transformation from steel plate to the whole machine.，Sold to construction sites in hundreds of countries and regions around the world、In the harbor dock，Sales to the European and North American markets are particularly prominent.，Sales continue to grow rapidly at a rate of doubling annually.。

“Our truss-type robot two-machine cooperation technology，It is the first use in the whole country and even in the world.，The improvement of efficiency is very huge.。”Xue Yutian, vice president of Sanyi Heavy Craft Institute, told reporters.，“In the past, this process required four workers to carry out welding work for a whole day.，Now two robots can be completed with high quality in four hours.。”

Because it's huge、Extremely heavy workpieces and thousands of components，The welding workshop with over 70% automation rate is not the workshop with the highest automation rate in Sany Heavy Industrial Park.。In the outrigger workshop of Sany Heavy Lift，The automation rate is over 90 percent，The automation rate of the painting workshop is as high as 100%。

All manufacturing links also benefit from the introduction of automation technology.，Product consistency and worker safety have also been greatly improved.。

In the welding shop，In the past, workers had to climb up to weld through tooling.，Operation is inconvenient，The occupied space is large。Nowadays，The welding gun is held in the hand of the robot.，The laser eye replaced the naked eye to determine the position of the weld.。With the support of high technology，The welding accuracy of each position of the frame can reach 0..01 mm——Less than 1 of the hair/10。While 100% of the painting workshop%Automation，It avoids the inhalation of toxic and harmful spraying dust by workers.，It also increases the utilization rate of spraying materials to nearly 100%。

From“Man-assisted machine”Become“Machine assistant”，More and more introduction of smart devices，The structure of human resources has also undergone tremendous changes.。Machine programming、Equipment operation and maintenance，It has become a common skill for workers in Sany Heavy Industry.，Reporters in the process of visiting the park，It is difficult to distinguish who is a worker on the spot.，Who is an engineer?。The top students from 985 and 211 universities are in the same place with the teachers.，Mix and match of engineers and technical workers，The new workforce of Sany is further accelerating the process of intelligent production process.。

Flexible manufacturing

If we break through the fully automatic blanking、Welding、Teamed automation hardware，It is a digital and intelligent change.“Flesh and blood”，Then the intelligent factory brain based on the manufacturing operation management platform as the core，It is the digital and intelligent transformation of Sany Restart.“ Soul ”，Help the company to achieve from“Gang”To“Soft”The transformation of，The production potential has been brought into full play.。

Cranes with rudimentary structures existed in ancient times.，Although the core function is simply lifting heavy objects.，However, a variety of product types and forms have been derived from the rich application scenarios.，The demand for flexible production capacity under intelligent guidance is very strong.。

In the product system of Sany Crane，Truck crane with truck size and lifting capacity of only 12 tons，There is also a maximum lifting capacity of 4500 tons.“The world's first crane”，The size of the two is similar to that of ants and elephants.。This is worth hundreds of millions of yuan.“The world's first crane”，It covers an area of nearly 4200 square meters.，About the size of 10 basketball courts，Four tracks and eight drives for the main engine，Length 216 meters with open arms，The weight lifted at one time is equivalent to more than 3000 cars.，It is a solid Big Mac.。

“Crane is a typical variety.、Products in small batches，The market is constantly changing.，The needs are complex and diverse。Therefore, only the means of intelligent manufacturing can be used.，Improve our ability to deliver with agility，Improve product quality，Reduce the cost of our products，In order to meet the market demand.。”Xie Tao, general manager of Sany Restart Business Department, told reporters.。

In a typical production link of Sany Restart，The production plan is transferred to theMOMLed by the central intelligent brain.，And then transmit it to the terminal robot program.，After waiting for the handling robot to deliver the workpiece in place，The terminal robot determines the workpiece through the machine vision system，And automatically according to the size of the workpiece,，Debugging the corresponding welding procedures in dozens of manufacturing schemes。

Past，Non-standard models customized by customers from all over the world according to construction scenarios，We can't produce a few in a year.。This kind of non-standard products，It is often produced by modern industrial assembly line.“The archenemy”，But after the intelligent transformation, the Sany Heavy Lift Factory，Yes, it is still possible.“Calm”Take orders。In fact，With the support of digital technology，Trinity Restart is not satisfied with“I can take orders”，It's more possible“I can do it well”“Can save energy”。

In the context of a high degree of digital intelligence，Key technologies、The production process is all online and controllable.。At the quality level，Even the tightness of a screw，Registration has also been achieved.，Ensure full traceability。In terms of energy conservation and emission reduction，Through real-time monitoring and management of the energy consumption of each production link，Precise control and optimization in the production process，Reducing water、Waste of electricity and raw materials，Reducing carbon emissions in the production process。

It is worth mentioning that，This whole set of intelligent factory brain is independently developed by Sany.，It has become the company's secret book.。Xue Yutian said：“As a benchmark to promote intelligent manufacturing in the industry，We attract a large number of colleagues to visit and study every day.，But the software system can't be learned.，This kind of thing has no standardized system and can only be self-developed.。If you don't know how the control logic is refined,，Then you'll never learn.。”

Looking back on the course of the company's digital transformation，Xie Tao could not help feeling.，“Digital and intelligent transformation is a top project.，The leader must go off in person.，Unity of thought，Only by pushing forward with all efforts can we realize the deep transformation of digital intelligence.。”There has always been a word of mouth among employees in Sany.，“Sany's Digital Transformation，Or turn over，Or capsize。”This sentence is Liang Wengen, chairman of Sany Group.，When the company comprehensively promoted the transformation of digital intelligence in 2018, it put forward，If we can't realize the digital upgrade, we will definitely“The boat capsized”，The success of transformation and upgrading will“Roll over”Become more powerful.。Since then，Sany Heavy Industry will be 5 every year.％More than 80% of the sales revenue is invested in technology research and development.，Digitalization is the major part of R & D investment。

Overseas promotion

Powerful intelligent manufacturing capability，It supports Sany to restart its attack on overseas markets.。

In the past three years,，Sany has ushered in a golden period of overseas business development.，Overseas sales have doubled year by year.。Xie Tao introduced，In the main product，Its crawler crane market position has remained the first in the world.，Truck crane、Full ground crane、The market share of products such as off-road cranes has also risen sharply.，The export volume is the first in China。

In the first four months of this year,，The proportion of Sany's overseas sales has been the same as that in China.，In some months, it even exceeded domestic sales.，And showed a sustained upward trend.，Production orders have been scheduled to the end of the year.。Among，Sales to traditional construction machinery power Europe and North America are particularly prominent.，Up to double year-on-year growth。In order to meet the growing demand for production，Sany has also launched another batch of technological transformation and intelligent equipment.，Improve production efficiency and product quality。

Actually，Due to the late start of industrialization,，The development of China's construction machinery industry has long lagged behind that of European and American countries.。In the field of cranes，China's first truck crane until the 1950s.，It was born by copying the products of the former Soviet Union.。However，Because the market driving force is insufficient.，As a result, the domestic large-tonnage lifting equipment is seriously lagging behind.，At that time, the lifting capacity of crawler cranes in China was only 50 tons.，1% of similar products in Germany/16。

It is the driving force of domestic demand，It has led enterprises, including Sany, to continuously strengthen their research and development.，Break through the manufacturing limit，Ranking among the world's top machinery manufacturing enterprises。In recent years, China's petrochemical industry、Electricity、 Iron and steel 、Architecture、Traffic、The upsurge of construction in infrastructure and other fields，Driving the continuous upgrading of super-large cranes.。

The first 1000-ton all-terrain crane in China、The first 400t crawler crane in China、The world's first 4500-ton crawler crane has been launched in Sany.。And from“The first one in China”To“The world's first”，The Development Course of Sany Restart，Witnessed China's construction machinery industry in the market、The historical process from catching up to leading in all aspects of technology。

Sany's high-speed expansion overseas，It is the epitome of the overseas expansion of China's construction machinery industry.。Data from China Construction Machinery Industry Association，2023，China's construction machinery exports totaled 341.4 billion yuan.，Year-on-year growth of 15.8%。The performance of leading enterprises going to sea is far better than industry average.，A number of enterprises including Sany Heavy Industry，It has achieved a historic breakthrough that the revenue scale of overseas market is higher than that of domestic market.。

Take the listed company Sany Heavy Industry as an example.，The company's revenue from overseas markets reached 432 in 2023..5.8 billion yuan，It accounts for nearly 60% of the total revenue.，In 2020, the proportion was only 11.%。At the same time，Gross profit margin of Sany's international business，Also up 4. 5% from a year earlier..42 percentage points，Up to 30.78%。Double promotion of sales scale and profitability，This proves the current situation of high-quality development of relevant enterprises in overseas markets.。

Xie Tao analysis said，In the next stage, the demand for lifting equipment in the domestic market will continue to be polarized.，Wind power、Large-scale bridges will continue to drive the demand for ultra-large crane equipment.；It benefits from the comprehensive revitalization of the countryside and the transformation of the old city.，Compact、The demand for flexible lifting equipment will also gradually rise.。Currently for the domestic market，On the one hand, Sany Heavy Lift continues to iterate the research and development technology of large cranes.，At the same time, speed up the development of small wheelbase.、Small Turning Radius Products，To adapt to the new market environment.。

Overseas markets，It will continue to be a key area for Sany to develop again.。Xie Tao thinks，In the next five years, the company will maintain rapid growth in overseas markets.。“We will continue to increase the pace of going out.，Under the concept of local management and service first，From the past export of products to the integration of global resources，Go all out to develop global business。In key overseas markets，The company invested in the construction of the crane production line.，Promote domestic intelligent manufacturing technology to overseas manufacturing。”Talk about the future，Xie Tao is full of ambition。
