The vast Xiangjiang River，The flow is endless。May 12，As the largest annual construction machinery industry event in Asia,，The Third Changsha International Construction Machinery Exhibition，Changsha International Convention and Exhibition Center、Grand Opening of Changsha International Conference Center。

Approaching the Sany exhibition area，The heavy weapons of the towering powers are arranged in an orderly manner.，It shows strong manufacturing strength.。The types of equipment on display are also more diverse than in previous years.，Up to 80 sets of exhibition equipment。This exhibition，It shows the high-quality development achievements brought about by the three-in-one transformation strategy.。

Three key models newly launched by Engineering Vehicle Division of Sany Group：Hybrid 424 dump truck、432 pure electric dump truck、416 pure electric dump truck made a big appearance in this exhibition.。

Hybrid 424 dump truck

  

Hybrid 424 dump truck is a model characterized by extreme fuel economy.，Compared with traditional fuel vehicles, the fuel saving rate of this model can be increased by 20%Above，The vehicle above the power performance can achieve a maximum power output of 660 horsepower.，Maximum climbing gradient>45%，It also has a conventional acceleration power function and a rapid acceleration overtaking mode.。

The weight of the whole vehicle，The vehicle adopts lightweight design.，Weight of complete vehicle 15T。In terms of endurance，The vehicle is driven by an electric system.，Range up to 700km，No need to worry about driving range and charging，At the same timeAMTAutomatic transmission，Can be equippedASLActive speed limit，And functions such as constant speed cruise and slope prevention，Good security，The ride is more comfortable。

432 pure electric dump truck

432 pure electric dump truck has the characteristics of extreme loading, safety and reliability.。The car uses a super-heavy suspension.+Overloaded axle、Three-layer girder+Frame of local five-layer girder、32m³Super large cargo box and other technologies。And according to the characteristics of different working condition，A planographic version was developed、Mountain version exclusive power chain，The maximum horsepower of the motor can reach 690，It can significantly improve operational efficiency.。

In terms of security，Strive to create lifting stability、Steady downhill、Three stable products with stable turning，Increase the roll rigidity of suspension，An integral six-turn cargo box is designed.+Double tail beam frame，Rear axle anti-drag torque increased by 60%。At the same time，Key parts of high pressure system，HaveIP68 Water resistance，The harness pipelines are arranged in layers separately.，Chassis harness is clear，Avoid potential safety hazard caused by interference and friction。

416 pure electric dump truck

416 pure electric dump truck with low energy consumption、Quick energy supplement、High security、High load、Advantage of high reliability。Through one scene and one strategyvcuCalibration，Different scenarios adopt their corresponding optimal strategies.，Achieve low energy consumption of working condition。

Vehicle lightweight design，Compared with similar products in the market，Weight reduced by 800kg，Further reduce driving energy consumption，Range up to 260km。At the same time，The strength of supplementary energy is excellent，500 is used.ADouble-gun quick charging，Charge rate increased by 20%，Charging only 1.2 hours，Achieve industry-leading。

Bearing、Excellence in safety performance，It is also a remarkable feature of the vehicle.。The whole vehicle is lightweight+The upper structure is optimized，Load one more square material at a time。In view of the large blind area of vision of urban construction muck truck、Problems with high security risks，416 electric dump truck has developed 360 electronic rearview mirror with head-up display and radar monitoring of right blind area.，And the occurrence probability of traffic accidents is reduced.，Achieve real high security。High requirements for refinement of vehicle pipeline，Each functional part has passed the bench test and 7500kmReliability road test，More reliable performance and quality。

At this exhibition，The Engineering Vehicle Division also held a hybrid technology conference.，The rationality and inevitability of the development trend of hybrid engineering vehicles were introduced to the visitors.。

Hybrid technology is the combination of two or more different power sources，A technology that gives full play to their respective advantages。The hybrid engineering vehicle has strong adaptability to working conditions.、Low fuel consumption、Long endurance and other advantages。Its hybrid system can achieve more efficient energy conversion under different working conditions.，At the same time, high temperature、High and cold、Plateau and other environments are more adaptable.，Therefore, it has good adaptability to working conditions.。

Although the hybrid started relatively late.，However, with the efficient and stable operation of the hybrid system and its efficient fuel saving rate,，Hybrid engineering vehicles are expected to achieve local precision explosion in the near future.。

In short，Hybrid engineering vehicle is an efficient and flexible vehicle option，In satisfaction“Four-stage fuel consumption”While demanding，Adaptable to different driving conditions，And provide more reliable mileage performance。Through comprehensive analysis of user scenarios and solid product development capabilities，Trinity will break through the earth.，Achievements in the field of engineering vehicles“The king of mixing”。

The 3rd Changsha International Construction Machinery Exhibition is an important platform to display the latest achievements of the global construction machinery manufacturing industry.。Sany Group is one of the leading construction machinery manufacturers in China.，By strengthening technology research and development、Improve product quality and service level.，Continuously promote the innovation of three modernizations，Realize the double promotion of product quality and enterprise value。Believe，On the road of continuous exploration and innovation，Sany Group will continue to lead the trend of industry development.。
