With the full implementation of China's "dual carbon" strategic goal, adapting to digital and green development has become the core of the current domestic and foreign manufacturing industry transformation and upgrading strategy. In the construction machinery industry, the continuous maturity of the "three electricity" technology and the gradual improvement of the industrial chain have led to the continuous reduction of the manufacturing and operating costs of the electrified equipment. The comprehensive performance and economic benefits advantages of the electrified equipment are attracting more and more attention. Electrification has become an important future direction of China's construction machinery.

"From oil to electricity" is not a day's work. At the starting line of the development of electrification, major enterprises and manufacturers are currently investing huge resources to accelerate the R&D layout, and making unremitting attempts to accelerate the mature landing of electrification products. Sany Group, as the top host manufacturer in the industry, started earlier. All business divisions have long been focusing on the electrification development of the full product spectrum, and gradually become the leading singer in this electrification "a hundred schools of thought contend" chorus.

Among them, Sany Crane has made remarkable achievements in the field of equipment electrification in recent years, both in terms of technology accumulation and market sales.

"The industry has higher requirements for the convenience and economy of electric cranes." In the interview, Yuan Dan, general manager of Sany Heavy Lift Electrification Company, said so. "Its fuel consumption throughout its life cycle is also very small compared with light trucks and other equipment, so its economy in terms of fuel and electricity savings has never been particularly good."

As a productivity tool of heavy assets, the downstream customers are most concerned about whether the electrified construction machinery can bring maximum benefits. Centering on this core demand, SANY has developed a new technical route in combination with the characteristics of fixed scene and fixed construction of cranes. In 2021, it launched the innovative product of plug-in cranes, which effectively improved the economic benefits of equipment and won a warm response from the market. "According to the scenario customization idea, we reduced the fuel consumption and emissions by about 70% with the low-cost equipment scheme; both the engine emission reduction and the customer economy have been greatly improved."

Since the introduction of the first conceptual equipment in 2013, the three heavy electrification teams have been making progress in the research and development of electric cranes with the core of providing customers with equipment with "lower cost, better performance and greater reliability". After years of iterations, the product technology has become more sophisticated, and the product series covering all levels of tonnage seems to be taking shape. In the four times of non road countries, Sany Crane, while meeting customers' demands for energy conservation, emission reduction and green construction in various scenarios through a variety of technical routes such as pure electricity and hybrid, is also laying a strong foundation for China's construction machinery to overtake at corners in the international market in the future.

First mover advantage into leading force

In the opinion of General Manager Yuan Dan, the key to the development of electrical machinery products lies in technical reserves and supply chain, both of which are at the leading level in the world. "At present, although most of our small tonnage fuel oil cranes have achieved the localization of parts, we are still subject to the supply of foreign parts in the manufacturing and iteration of large tonnage lifting equipment; after the equipment is electrified, these problems will no longer exist, and our technology and industrial chain can completely exceed the existing international benchmark!"

Compared with being controlled by others in the field of traditional cranes, the local construction machinery brands represented by Sany have demonstrated strong market competitiveness in the field of new energy cranes. The overseas sales volume has grown rapidly, taking the first step of overtaking at a curve. Taking the high-end market in Europe as an example, Sany's pure electric crawler crane has achieved remarkable results, and achieved rapid growth in sales with its strong competitiveness. "Electric cranes are currently at a stage of rapid growth in market penetration. In 2022, the sales scale of the whole industry is expected to be ten times larger than that of last year. At the same time, we have also received a large number of orders in the European market. Therefore, we believe that the year after tomorrow will be an outbreak of the pure electric market." As for the future market prospects of the three heavy electrical machinery, General Manager Yuan Dan concluded this way.According to professional estimates, the market penetration rate of Sany electric crane products will reach about 18% in 2022 and at least 30% in 2023. At this critical moment of development, create safe and mature new energy products for customers, so that global customer groups can truly feel the high value of electrical and mechanical products; To promote the benign and orderly development of the industry and consolidate the first mover advantage of China's new energy crane industry is not only the responsibility of Sany Crane as the industry leader, but also an important mission that all leading enterprises of China's construction machinery must jointly undertake.

At present, the electric upgrading of construction machinery is the trend of the times, and the leading construction machinery enterprises around the world have in-depth layout of electric equipment. The gate of the construction machinery electrification market is about to open. How can Sany Crane write a more wonderful "electromechanical story" in the tide of the times? Industry colleagues and users are full of expectations, looking forward to the future of the electromechanical world! Editor/Zhao E
