Recently，Sponsored by the Information Center of SASAC of the State Council，People's Daily New Media Center、New Media Center of Xinhua News Agency、China News Network、People's Network, People's Video and other mainstream media cooperation“Our ten years.@Coordinates China”Online theme publicityStart up，To be constantly refreshed.China span、Chinese precision、Height of China、Depth of China、China's strength、Chinese speedFor longitude and latitude，Focus on the major achievements of representative infrastructure construction and scientific and technological innovation since the 18th National Congress of the Communist Party of China，Show the Chinese builders to overcome difficulties、The courage to challenge the limit、Boldness and wisdom。
October sixth，“Coordinates China”The 24th issue of the series of theme films was launched“China's strength”Of《Pull out the dome》，Focus onThe first one in China“Two in one”Crawler Crane——TrinitySCC52000TMCrawler Crane，Thumbs up for the great power，Applaud the great power to promote the development of the new era。
SCC52000TMIt is jointly developed by China Nengjian Guangdong Thermal Power and Sany Group.，The first one in China was successfully launched on April 28, 2022.“Two in one”3000t Crawler Crane。September 25, 2022，The crane completed the Taipingling nuclear power project in Guangdong.“Hualong One”Millimeter-level precise hoisting of 225-ton dome of nuclear power unit，For“The most important weapon of the country”Contribute to the power of hard-core heavy industry。How to realize the hoisting of nuclear power dome？Hoisting with great strength“Big Mac”How to transform and fit？Let's see↓
Large Wind Turbine blades weighing more than ten tons
Standing tall，Dance with the wind
Tens of tons of Shield Machine cutterhead
Dig the underground city
Witness“Infrastructure maniac”The vigorous power of
Hundreds of tons of nuclear power dome
A huge umbrella open.“Protective cover”
Protect the safety of nuclear power......
These are related to the national economy and the people's livelihood.
“Big Mac”Behind the smooth hoisting
All hiding one.“Super equipment”
Extra large tonnage crane
PART1
How heavy is the power of a thousand Jun?？
This 3000-ton crawler crane
Upgrade from 1600 tons to 2000 tons
Together with another 2,000-ton crawler crane
“Two in one”Modification“Fit”And become
The maximum lifting capacity is 3000 tons.
The longest jib of the crane is 216 meters.
（The main boom is 108 meters+Jib 108m）
It is equivalent to the height of about 7 water cubes.
Track frame length 17m，The equivalent of a six-storey building
Spread your arms and cover an area of 1600 square meters.
The size of five basketball courts.
What is the concept of lifting 3000 tons at a time?？
3000 tons equals 6 million Jin.
Equivalent to 2000 Vehicles, about 1.A five-ton car
Behind the lifting of a thousand tons
It must have great power.
3000t crawler crane
It is well deserved“Big Mac”
PART2
How to achieve
100-ton nuclear power domeMillimeter-level precision hoisting？
Dome is an important barrier for the safety of nuclear power plant.
Is to ensure the integrity and tightness of the reactor building
An important part of achieving inherent safety
September 25, 2022
After 3000-ton crawler crane is disassembled
One of the 2,000-ton crawler cranes was completed
Guangdong-Hong Kong-Macao Greater Bay Area
“Hualong One”Generation III nuclear power plant
——CGN Taipingling Nuclear Power Project
Lifting of the dome in the containment of Unit 2
The dome weighs 225.8 tons
It's a 45-meter diameter.、High 13.7 m hyperboloid hemisphere
The area is equivalent to 4 basketball courts
To put this one.“Big guy”After being hoisted to a height of 70 meters,
The smooth control falls on the nuclear island cylinder about 45 meters high.
And the deviation should be controlled at the millimeter level.
At the same time, the deflection under the influence of wind should also be considered.
Thermal expansion and contraction under temperature change
This is a big challenge.
In order to ensure the safety of dome hoisting
Hoisting technicians have carried out the hoisting process many times.
BIMSimulation calculation of intelligent nuclear power construction technology
At the same time, closely monitor the weather conditions before hoisting.
Conduct a simulation exercise、Emergency drill、Trial lifting of dome, etc
During the 2-hour hoisting process,
The accuracy is controlled at millimeter level.
PART3
“Iron and steel”How do twin stars transform and merge?？
This steel-cast hoist.“Big Mac”
“Fit”The process is not complicated.
Just get on the car and add two beams.、Longitudinal beam
Main stressed parts such as front platform shall be added after getting off the train.
And then through modular assembly
The masts of the two crane Trucks are、Main boom and auxiliary boom
“Combine two into one”Make up a whole
It's a success“Fit”Here we go
One crane Truck is used as the main engine.
The other crane Truck provides power source.
One driver can control it.
Even more subtly,
It can be on the order of 3000 tons.“Come out”
Yes, too“Transformation”Disassembled into 2 cranes operating independently
Some typical operating conditions
It even reaches 1.+1＞The effect of 2
In addition
It also carriesOmnidirectional visual intelligent operation
And intelligent fault diagnosis system
Configure wireless remote control at the same time
Walk、Promote、Rotation, etc
A series of high-precision actions
Can be achieved by wireless remote control.
Really let“Big guy”Have“Great wisdom”
China Super Heavy Crawler Crane
From scratch、From small to large
The course from complete import to world leading
Fully demonstrated
“Made in China”Hard core strength
It is also the epitome of China's rapid development.
