Major innovation achievements! The world’s first unmanned bulldozer appeared in Kazakhstan excavator track link
The world’s first unmanned bulldozer, jointly manufactured by Huazhong University of Science and Technology and Shantui Engineering Machinery Co., Ltd. (“Shantui” for short), has been tested nearly 100 times and can accurately execute instructions.Kazakhstan excavator track link
Zhou Cheng, the technical director of the project and a professor at the National Digital Construction Technology Innovation Center of Huazhong University of Science and Technology, said that the research and development of the unmanned bulldozer started in early 2019. The research team conducted system tests in the field more than ten degrees below zero in winter, and finally realized the functional integration of the unmanned bulldozer, such as pushing, shoveling, leveling, transportation and integration.
Downslope bulldozing, oblique angle bulldozing, centralized bulldozing in separate piles… At the end of last month, the unmanned bulldozer DH17C2U successfully completed the test of version 2.0 at a test site in Shandong. Wu Zhangang, director of Shantui Intelligent Construction Research Institute, said that as the world’s first unmanned bulldozer, it can accurately execute operating instructions.Kazakhstan excavator track link
The world’s first steam crawler bulldozer was born in 1904. It is a major change from manned to unmanned. The driverless bulldozer system with independent intellectual property rights is one of the 20 2021 Hubei AI major innovation achievements (scenes) released by the Science and Technology Department of Hubei Province.Kazakhstan excavator track link
“The traditional manned bulldozer operates in three shifts for 24 hours. The labor cost of each driver is 1000 yuan per day, and it will cost at least 1 million yuan per year.” Lu Sanhong, who drives bulldozers all the year round, has calculated a sum of money. If unmanned driving is used, the labor cost saved is considerable.
Zhou Cheng said that the price of driverless bulldozers is higher than that of manned bulldozers, but it can free people from the environment of high repetitive labor, high pollution of operation scenes and high risk of operation. This year, driverless bulldozers will accelerate their implementation and application in mining, road traffic engineering, infrastructure construction and other scenarios.
In the opinion of Professor Yang Guangyou, School of Mechanical Engineering, Hubei University of Technology, it is only a matter of time before unmanned bulldozers replace manned bulldozers. Zhang Hong, a professor level senior engineer of CCCC Second Harbor Engineering Bureau Co., Ltd., believes that unmanned bulldozers are a mainstream trend in the development of construction machinery in the future.
As one of the top 50 global construction machinery manufacturers, Shantui has an annual production capacity of 10000 bulldozers. Jiang Yutian, president of Shantui Intelligent Construction Research Institute, said that Shantui would timely introduce unmanned bulldozers to the market according to its technical maturity.
New favorite in mining area — driverless mining truck
Previously, the first 290 ton 930E unmanned mining truck in China, which was jointly reformed by Aerospace Heavy Industry and Zhuneng Group Heidaigou Open pit Coal Mine, affiliated to Aerospace Sanjiang, operated continuously with four manned mining trucks, one 395 electric shovel and one bulldozer in Heidaigou Open pit Coal Mine. During this period, typical operation scenarios of the whole process, such as obstacle avoidance, car following, obstacle clearing, loading, car meeting and unloading, ran smoothly, without faults No manual connection.Kazakhstan excavator track link
In June 2020, the truck will complete the line control transformation of the whole vehicle, the installation of 4D optical field equipment and laser radar and other vehicle sensing systems, the collection and production of work area maps, the test of driverless trucks in closed sites, the collaborative operation of driverless trucks and shovel and other auxiliary equipment, and the intelligent dispatching and debugging.
According to the introduction of Zhuneng Group, 36 mining trucks have been transformed into driverless trucks, 165 trucks are planned to be transformed into driverless trucks by the end of 2022, and more than 1000 auxiliary operation vehicles such as existing excavators, bulldozers and sprinklers will be managed in collaboration. After the completion of the project, Zhungeer mining area will become the largest unmanned transportation open pit mine in the world, as well as the intelligent mine with the largest number, brands and models of unmanned mining trucks in the world, which will effectively improve the safety and production efficiency of mine operations.
