The mighty Xiangjiang River flows endlessly. On May 12, as the largest annual construction machinery industry event in Asia, the 3rd Changsha International Construction Machinery Exhibition was grandly opened at Changsha International Convention and Exhibition Center and Changsha International Convention Center.

Approaching the Sany exhibition area, the majestic giants and heavy equipment are arranged in an orderly manner, demonstrating strong manufacturing capabilities. The types of equipment exhibited this time are also more diverse than in previous years, with as many as 80 exhibiting equipment. This exhibition demonstrated to all walks of life the high-quality development results brought about by the transformation strategy of 313 Transformation.

Three key models newly launched by Sany Group's engineering vehicle division: hybrid 424 dump truck, 432 pure electric dump truck, and 416 pure electric dump truck were unveiled at this exhibition.

Hybrid 424 dump truck

The hybrid 424 dump truck is a model characterized by extreme fuel efficiency. Compared with traditional fuel vehicles, the fuel saving rate of this model can be increased by more than 20%. The vehicle above the power performance can achieve a maximum power output of 660 horsepower and a maximum gradient of >45%. , and has conventional acceleration assist function and rapid acceleration overtaking mode.

In terms of the weight of the whole vehicle, the vehicle adopts a lightweight design, and the weight of the whole vehicle is 15T. In terms of battery life, the car is driven by an electric system, with a mileage of up to 700km. There is no need to worry about mileage and charging. At the same time, it adopts an AMT automatic transmission, which can be equipped with ASL active speed limit, cruise control and slope prevention. And other functions, good safety, more comfortable driving.

432 pure electric dump truck

The 432 pure electric dump truck has the characteristics of extreme loading, safety and reliability. The car adopts technologies such as super-heavy-duty suspension + super-heavy-duty axle, three-story girder + partial five-story girder frame, and 32m³ super-large cargo box. And according to the characteristics of different working conditions, the exclusive power chain of the plain version and the mountain version has been formulated. The maximum horsepower of the motor can reach 690, which can significantly improve the operating efficiency.

In terms of safety, we have made every effort to create a three-stable product that is stable in lifting, downhill, and turning, and the roll rigidity of the suspension has been improved. An integral six-turn cargo box + double tail beam frame has been designed, and the rear axle is dragged backwards. Torque increased by 60%. At the same time, the critical parts of the high-voltage system have IP68 waterproof capability, and the wiring harnesses are arranged separately and layered. The chassis wiring harness is clear and clear, avoiding potential safety hazards caused by interference and friction.

416 pure electric dump truck

The 416 pure electric dump truck has the advantages of low energy consumption, fast energy replenishment, high safety, high loading and high reliability. Through VCU calibration for one scenario, one strategy, different scenarios adopt their corresponding optimal strategies to achieve low energy consumption under working conditions.

The lightweight design of the whole vehicle, compared with similar products in the market, reduces the weight by 800kg, further reduces driving energy consumption, and the cruising range can reach 260km. At the same time, the energy replenishment capability is excellent, using 500A dual-gun fast charging, the charging rate is increased by 20%, and it only takes 1.2 hours to charge, reaching an industry-leading level.

The excellence of load bearing and safety performance is also a remarkable feature of the vehicle. The weight of the whole vehicle is reduced + the structure of the upper body is optimized, and one more material is installed each time. In view of the large blind spots and high safety risks of urban construction muck trucks, the 416 electric dump truck has developed a 360 electronic rearview mirror with a head-up display and radar monitoring of the blind spot on the right side, which reduces the probability of driving accidents and achieves truly high safety. The refinement requirements of the vehicle pipeline are high, and all functional parts have passed the bench test and 7500km reliability road test, and the performance and quality are more reliable.

At this exhibition, the Engineering Vehicle Division also held a press conference on hybrid technology to introduce the rationality and inevitable development trend of hybrid engineering vehicles to visitors.

Hybrid technology is a technology that combines two or more different power sources to give full play to their respective advantages. Hybrid engineering vehicles have the advantages of strong adaptability to working conditions, low fuel consumption, and long battery life. Its hybrid system can achieve more efficient energy conversion in the case of matching with different working conditions, and at the same time, it is more adaptable to high temperature, high cold, plateau and other environments, so it has better adaptability to working conditions.

Although the hybrid started relatively late, with the efficient and stable operation of the hybrid system and its high fuel economy, hybrid construction vehicles are expected to achieve localized precision explosions in the near future.

In short, hybrid engineering vehicles are an efficient and flexible vehicle choice, which can adapt to different driving conditions while meeting the four-stage fuel consumption requirements, and can provide more reliable mileage performance. Through comprehensive user scenario analysis and solid product research and development capabilities, Sany will surely break through and become the king of hybrid vehicles in the field of engineering vehicles.

The 3rd Changsha International Construction Machinery Exhibition is an important platform to showcase the latest achievements of the global construction machinery manufacturing industry. As one of the leading construction machinery manufacturers in China, Sany Group has continuously promoted three-innovation innovation by strengthening technology research and development, improving product quality and service level, and achieved double improvement in product quality and corporate value. I believe that on the road of continuous exploration and innovation, Sany Group will continue to lead the trend of industry development.Editor/ZhangHui
