Xugong Group
Anchoring high-end、Intelligent、Green development direction
Technical climbing“High” Industrial orientation“New”
Hebei Jingxian 200MW Wind Farm，A bright yellow XCMG 4000-ton all-terrain crane will lift more than 120 tons of engine rooms in turn.、40-ton wheel hub，And 3 pieces 95 meters long.、The 28-ton fan blade is lifted high.，Precisely connected to the 162-meter-high tower for assembly。
Developed last year“3000 tons”，Lifts up to 190 tonnes at a height of 160 metres，And this time.“4000 tons”，It can lift 230 tons of weight at a height of 170 meters.。This is the seventh time that Xugong Group has refreshed its own 1000-ton crane research and development record.。
In recent years，XCMG Anchoring High-end、Intelligent、Green development direction，Develop independent innovation、“Intelligent change from digital to network”、Green and low-carbon transformation，Achieve technology climbing“High”、Industrial orientation“New”。
Deepen research and development and concentrate on tackling key problems
4000t all-terrain crane，What's good about it?？
“At present，China's wind power industry is developing rapidly.，As the fan becomes larger,、Develop in a higher direction，The matching installation equipment should run ahead.。”Li Changqing, the chief designer of the equipment, introduced.。
Lifting weight increases by 1 ton、Lifting height increases by 1 meter，The requirements for crane performance and the difficulty of research and development will increase exponentially.。Maximum lifting tonnage from 3000 tons to 4000 tons，There are two most difficult challenges.：Hoist from high altitude、Load transfer。
“Structural innovation in R & D，Make more stress points，You can reduce the deformation.、Increase the stiffness of the boom，Lifting crane load capacity。”Li Changqing said，Over the past two years, the R & D team has conducted more than 2000 structural tests.，Not only should we consider increasing the stress point，Also consider the distribution of forces at each point.，Form a lifting force。
For cranes，Strong force at the moment of horizontal lifting，“Joints” Easy “Dislocated”。What to do？The R & D team thought，At“Joints”Add a protective cover on the outside——Brace device。The device consists of 4 pillars.，Pull the top two up.，The lower two are propped downward.，It can also be opened and closed flexibly.，Solved“Fragile joints”Question。
At the wind power project site， Many “Big windmill”Between a few kilometers to more than ten kilometers.，During the transfer of large crane，If you go through the ditch、Hilly pavement，Tilt will occur，Only split shipments are allowed，It takes time and effort、The cost is still high。To this，The R & D team innovatively adopts the disconnected axle in the crane chassis.，Each wheel can move up and down independently.，Even if one side of the tire is raised，The other side will not be affected.，O as to keep the Vehicle body stable.。
Ding Honggang, Technical Director of Xugong Group Heavy Machinery Co., Ltd.，The 4000-ton all-terrain crane that has just completed its first lift，It's the groupGA major product of the Generation 2 technology platform。From 2019，The group has invested more than one thousand engineers.GGeneration 2 Technology Platform Technology Development，At present, 21 key technologies have been released.、31 key components，Overcome 30 difficult problems，Form 11 original technologies，The whole product line has reached the leading level in the industry。
Digital Intelligence Fusion Enabling Scenario
In the parking lot of Xugong Mining Machinery Co., Ltd.，Several driverless mining cards just off the production line are parked.。Application of Unmanned Driving Technology，It can avoid the safety risk of manual driving in harsh environment.。
Look carefully，The appearance of the driverless mining card is very scientific and technological.：Two on the front of the car“Antennae”It is a high-precision positioning antenna，All over the body in different colors“Widget”，Laser radar, respectively.、Millimeter wave radar、HD camera，As well as various sensor and that like。
“This is the Vehicle.‘ Eye ’And‘ Nerves ’，Transmit the sensed information back to the on-board computing unit，‘ Brain ’Will judge its own position.、Status，O as to arrange the work according to the task list of the dispatching center。”Wang Yong, Director of Customer Center of Xugong Mining Machinery Engineering, introduced.，Based on the precise control of the environment，Unmanned mining card can achieve 24 hours“Continuous rotation”。
Front of each Vehicle，And a small square box.。“This is‘Intercom’，Rely on it to achieve car and car.、A dialogue between that vehicle and the dispatch cent。”Wang Yong explained，Developed by XCMG“Truck dispatch system”，The vehicle passes“Intercom”Send and receive signals automatically，Tell each other“ Who am I ”“Where am I”“Who else is near me?”，Coordinate the queuing order、Avoidance sequence、Loading and unloading positions, etc，Optimize the capacity of teamwork through overall scheduling。
“Right now，Large-scale development of mine Transport Vehicles、Automation、Fewer people development has become a trend。”Wang Yong introduced，At present，XCMG's driverless mining card has been applied to more than 10 large mines in China.，Form“Digital intelligence fusion”New application scenarios。Take the mine project in Chifeng, Inner Mongolia as an example.，Five driverless mining cards can save 6 million yuan in labor cost every year.，An average of 2 hours more per day，While reducing vehicle maintenance.、Fuel consumption and safety management cost，10% improvement in energy extraction efficiency%Above。
Ecological priority and green transformation
XCMG New Energy Power Technology Co., Ltd.，A 102-meter-long semi-automatic trial production line of power batteries，By manual sorting、Robot grab，Close fit、Interlocked with each other，Complete battery core pretreatment、Multiple working procedures such as battery core stacking。
“Xugong produces batteries.，It is also an equipment manufacturing industry.‘Your own battery’。”Shao Xingguo, deputy general manager of the company, introduced.，Last year, the company took the lead in developing a special power battery pack for construction machinery.。After the mass production line was put into operation in June this year，It is expected to be offline every 15 minutes.，It not only realizes the breakthrough of enterprise independent power battery from scratch, but also realizes the breakthrough of enterprise independent power battery from scratch.、Safe supply of core components of new energy products，It will also expand new business growth sectors.。
Why produce“Your own battery”？“This stems from the Group's new energy strategy.。”Shao Xingguo said，In 2019, the Group established the New Energy Research Institute.，It was later upgraded to a research Institute.，XCMG has deployed photovoltaic、Energy storage to new energy vehicles，Then to the whole solution of battery core and charging station.，New energy batteries are an important part of the green supply chain.。
Stacking link on the production line，The assembly robot wields a manipulator.，Heat insulation material is inserted between the battery cores。The complex working conditions of construction machinery put forward to the battery.“High security、High and low temperature resistance、Impact resistance”And other special requirements，XCMG Tackles Key Technical Route，Enhance the competitiveness of new energy host through technological innovation of power battery pack。
XCMG Intelligent Loader Manufacturing Base，Wear“Green mountains are green”The loader of the coat runs on the test field.。Open the power system at the back of the vehicle，Expose the installed battery pack，Assistant to General Manager of XCMG Scraper Division、Guo Wenming, President of Loading Machinery Research Institute, introduced.：“Put it on‘Special battery’After，Each new energy loader works 3300 hours per year.，42 tons of fuel can be saved.，Reduce carbon emissions by 36 tons。”
Secretary of the Party Committee of XCMG、Chairman Yang Dongsheng said，To help achieve“Double Carbon”Aim，The Group took the lead in releasing the outline of the Carbon Peak and Carbon Neutralization Action Plan in the industry.，Develop the construction of carbon emission control system in the industrial chain，Development of digital carbon emission control platform，Form a package of carbon reduction and pollution reduction solutions for the construction machinery industry chain。2023，The carbon emission intensity of the Group will be reduced by nearly 15% compared with 2020%。
Xugong has been on the way to climb.To“New”Move forwardTo“Reality”ForceTo“Quality”Break through
Unswervingly promote high-quality development
