The SY35U Sany miniature unmanned excavator, which can dance in the street, became the "star" of the exhibition, equipped with Sany's self-developed unmanned work suite, which can be remotely controlled by remote video using advanced intelligent algorithms to autonomously complete pre-set actions. "It can enter dangerous construction areas instead of people, and can realize cluster intelligent operation in the future." Sany Heavy Machinery Small Excavation Research Institute Project Manager Wang Su No. said.

Hunan, Changsha, occupies an important place in the map of the global construction machinery industry. Hunan is China's largest engineering machinery manufacturing base, the main business income of about 26% of China's total, ranking first in China's construction machinery industry cluster. Hunan is the largest construction machinery manufacturing base in China, accounting for 26% of China's total main business revenue, ranking first in China's construction machinery industry cluster. These unique market advantages and industrial resources also make it possible to hold this exhibition in Changsha with the theme of "Intelligent New Generation Construction Machinery".

In the face of the rapid development of a new round of industrial change represented by intelligent manufacturing, digitalization, networking, intelligence is increasingly becoming a major trend in the development of manufacturing. In Changsha, to embark on the new road of intelligent manufacturing, has become the government and enterprises *** knowledge and focus on the direction of force.

As early as July 2015, Changsha was the first in China to release the "Changsha Intelligent Manufacturing Three-Year (2015-2018) Action Plan" to promote the transformation and upgrading of Changsha's manufacturing industry, improve quality and efficiency, and comprehensively enhance the overall competitiveness of the industry. After years of meticulous cultivation, Changsha's intelligent manufacturing has reached new heights, and the total number of state-level intelligent manufacturing pilot demonstration enterprises (projects) has reached 27, ranking the first in China's provincial capital cities.

The enterprise side is also a lot of action. Seizing the opportunity for development, Sany launched heavyweight unmanned equipment such as unmanned excavators, unmanned rollers, unmanned cranes and firefighting drones. "We want to seize the opportunity of intelligence and realize digital transformation." Sany Heavy Industry Chairman Liang Stegen said, this exhibition Sany **** 68 sets of "strongest" host equipment exhibition, of which 90% are brand new products. On the first day of the exhibition, Sany harvested orders and intentional orders of more than 1 billion yuan.

Another construction machinery company in the same city, Zoomlion, with 9 categories of 66 new 4.0 products at the exhibition, its Zhongke Yungu set of industrial Internet of Things, the Internet, cloud computing, big data technology in one of the products, through the collection of real equipment data and in-depth analysis of the data, can provide customers with equipment anomalies, start-up situation, operating anomalies, operating conditions, such as analysis of statistical data.

When building the Moscow Southwest Ring Road in Russia, Changsha-based China Railway Construction Heavy Industry (CRCHI) specially developed five shield machines for it that can work in the extremely cold environment of minus 30 degrees Celsius. "It set a construction record of digging up to 35 meters per day." Liu Feixiang, party secretary and chairman of the board of directors of China Railway Construction Heavy Industry Group, introduced that at present, Railway Construction Heavy Industry has successfully developed super underground engineering equipment such as large-diameter full-section shaft boring machine, kilometer-level super-advanced geological exploration equipment, and drilling and blasting method tunneling intelligent equipment machine group.

Construction machinery "Hunan army" of intelligence is not only reflected in the product. Changsha Bluestar Intelligent Technology Co., Ltd. is able to collect and analyze the complex data parameters generated by the increasingly intelligent construction machinery, and then propose solutions to help manufacturers optimize product design.

"China's machinery technology products have done relatively well, but not enough in the system control and information technology, what we want to do is to make up for this short board, so that the machinery is truly intelligent." The company hopes to help more small and medium-sized enterprises "go out" through information technology, intelligent technology.

From small to large, from weak to strong, construction machinery "Xiangjun" to seize the wind of information technology and intelligent manufacturing, through breakthroughs in key core technologies on the effort, in the design of intelligent, production intelligence, management intelligence, operation and maintenance intelligence, product intelligence, has ushered in the The situation of "a leap of a horse".

"Changsha has a lot of well-known brands of construction machinery, in terms of intelligence, digitalization is worthy of peer learning, we are also here to learn from the experience." Chen Lin, general manager of Case Construction Machinery (Shanghai) Co., Ltd, said Case wants to find partners in Changsha.

In the future, construction machinery equipment will develop towards intelligence and big data. At present, Changsha is focusing on the construction machinery industry into a world-class advanced manufacturing cluster, to the global value chain in the high-end.

Here industry experts said that although Changsha's construction machinery field of intelligent advancement day by day, but there are still many short boards need to be made up for, such as some of the key core technology is still subject to constraints, part of the world-renowned machinery manufacturing enterprises to be introduced. "We must continue to leverage the 'Internet +', artificial intelligence to seize the opportunity for development, at the same time to see the wise and make up for the shortcomings, in order to ensure that the reputation of the 'capital of China's construction machinery' does not fall on the sidelines.
