Pumping concrete from Shenzhen Saige Square to more than 300 meters high“Become famous in World War I”，To the Hong Kong International Finance Centre to be crowned at 406m.“China's pump king”，Then go to the Shanghai Tower and pump it to 620 meters.“The world's king of pumps”Laurel……Constantly refreshing the height of the world，It explains the strength and confidence of Chinese manufacturing.。
For more than 20 years，As the core figure of technological innovation of Sany Group，Yi Xiaogang led the team to attack the high-pressure pumping of concrete.、Ultra-long boom design and core hydraulic components of construction machinery“Stuck in the neck”Key technologies，It solves the technical bottleneck from key components to the whole machine.，Make efficient、Environmentally friendly concrete construction methods have been rapidly popularized in China.，High-pressure Concrete Pumping technology and industry in China from scratch、From following to surpassing、Finally, it has made great contributions to the world's advanced ranks.。
“Countries and industries need it.，I am duty-bound”
Early 1990s，Super high-rise、Long-distance concrete pipeline pumping technology is monopolized by foreign countries，Trolleys are still used in domestic construction.、Tower Crane and other traditional ways，The construction efficiency is low，Environmental pollution is serious。
Spring 1995，Sany Heavy Industry, which has just been established, has encountered bottlenecks in technological development.，Chairman Liang Wengen is thirsty for talents。Yi Xiaogang, who works at the Beijing Institute of Machinery Industry Automation of the Ministry of Machinery Industry, was appointed at the critical moment.，Give up the superior working and living conditions in Beijing.，To the remote town of Xingsha in Changsha County.“Pioneering”，Join this private enterprise with less than 20 R & D team。
“Be in a hurry to bear hardships，A fool's talent”“If you can't do it, there's nothing left.”……Yi Xiaogang ignored the opposition of his relatives and friends.：“Countries and industries need it.，I am duty-bound！”
After that，On the construction site、Yi Xiaogang can be seen everywhere at the debugging site.。In order to see the debugging results at the first time，He was on the scene day and night.。The thick work clothes were wet and dry.，Dry and wet。Even if you're sick，He also discussed the technical plan while receiving infusion in the office.。As an expert in hydraulics, he combined hydraulics with computer control.，It solves the industry problem of low pumping height.。
When the concrete trailer pump is switched between high and low pressure，It is usually necessary to switch different pipes.。“No tubes，Make a valve that can rotate 90 degrees.，Whether the problem can be solved？”Yi Xiaogang's bold design was strongly opposed by workers and workshop directors.：“Tubes have always been used abroad.，The client didn't say no.，Why should we change?？”
“Is it true that what is done abroad must be the best?？Isn't it done abroad?，Must we not do it?？”Yi Xiaogang asked in a rapid-fire manner.。After that，A hydraulic manifold valve group with a completely different working principle from the original product is designed and implemented.，The first patent of the enterprise was also born.。
Yi Xiaogang thinks，Innovation is a culture.、An idea、A kind of courage。He brought it up“Everything comes from innovation”“Break the fear、Be bold and innovative”“No work is too much.，Creation is ability.”Such innovative ideas have been condensed into the spiritual code of the R & D team.，It infects and inspires generations of new R & D personnel.，It has become the soul of Sany's cultural self-confidence.。
“Where‘Stuck in the neck’Here we go，Break through from there.”
37 meters、42 meters、46 meters……Considered by the industry“Every additional meter is more difficult than climbing the sky.”Field of long-boom pump Truck，Yi Xiaogang took the lead in tackling key problems，Climb higher step by step，“Vibrating arm”Yang Wei。December 2007，Sany Group's 66-meter long-arm pump Truck with 15 core technologies has been recorded in the Guinness World Records.，And then refreshed 72 meters.、The world record for the 86-meter pump Truck。
I never expected it，The development of long-boom pump trucks has encountered the use of high-strength steel plates for booms by foreign companies.“Run out of food”，Raw materials“Stuck in the neck”The problem was laid out.，Forcing Sany to stop production。
Once again, I have tasted the pain of being controlled by others.，Yi Xiaogang once again shouldered the heavy responsibility of technical fortification.。He is not a student of metal materials.，Locked himself in his office.，Look up information day and night.、Design scheme；Summer，In a heat treatment workshop with a high temperature of more than 40 degrees.，He stuck to the stove.，Keep an eye on every parameter.，Constantly debugging……That's all，After more than a month of arduous experiments day and night,，Yi Xiaogang leads the team，The steel plate with particularly high tensile strength was made.。
“Where‘Stuck in the neck’Here we go，Break through from there.。Core components and core technologies must be in their own hands.！”Yi Xiaogang said，“It took us more than three years to do nearly 10,000 trials.，More than 40000 sets of data have been obtained.，Very valuable，Our goal is to make our material perfect.，Make the world's most powerful boom。”
Solution of raw material problem，It has also brought huge profits to enterprises.。It takes 28000 yuan to import a ton of high-strength steel.，It only costs 7000 yuan to produce a ton by oneself.，It takes about 20 tons of steel to make a pump truck.，The annual production of 6000 pump trucks is calculated.，Saving more than 2.4 billion yuan……
Through independent R & D and collaborative innovation，Special Chassis of Sany Group、Engine、Controller、Cylinder and other key components have independent intellectual property rights and production capacity.。“Now try to block us again.，It's very difficult.。”Yi Xiaogang said。
“China Intelligent Manufacturing should do better than others.，We must break a new path.”
The No.18 factory building of Sany Group Changsha Base is called“The Smartest Factory Building”，There is a Concrete Pump every 45 minutes.“ Birth ”。The equipment born in this workshop，Undertaking 90% of the world's%Concrete Pumping tasks for skyScrapers over 500 meters。
2019，Yi Xiaogang is actively involved in the wave of intelligent manufacturing.，Shoulder Trinity“Lighthouse factory”The important task of upgrading and transformation。
In the heavy equipment production workshop，Automatic assembly welding of large and heavy structural parts，It's a big challenge.，Error is required to be less than or equal to 0.1 mm，But for a long time,，The error is 0.4 to 0.Swing between 5 mm。“I was in a hurry during that time.，Because this is‘Lighthouse factory’One of the most critical points.。”Yi Xiaogang began to tackle key problems with the engineers of Sany Group Research Institute.。
Every morning，First thing he does when he gets to the office.，Is to turn on the computer and look back at the surveillance video of the previous night's test.，Identify existing problems，Revise the technical scheme together with the engineer。This process lasted for two months.，Finally, the team boldly abandoned the conventional practice of judging position only by visual recognition.，Solved the problem。
“I always have a scene in my mind.，That is, China Intelligent Manufacturing should do better than others.，We must break a new path.。”Yi Xiaogang knows very well，Only continuous innovation，So as not to be eliminated.，He will continue to take the pace of innovation and creation.，Writing the Legend of Intelligent Manufacturing in China。
