In 2023, China Heavy Duty Automobile Group Co., Ltd. achieved operating income of 173.1 billion yuan, an increase of 44%; Vehicle sales of 334,000 units, the heavy truck market share of 26%, ranked first in the domestic heavy truck industry sales, market share; Heavy truck exports of 130,000, an increase of 47%, ranking first in the industry…
Behind the bright data is the successful exploration of intelligent development and comprehensive promotion of new industrialization by China Heavy Duty Automobile Group Co., LTD. (hereinafter referred to as “SinotruK Group”).
On August 21, the “number” in the “new” – Decoding the new industrialization “network theme publicity campaign entered SinotruK Group to explore the” confidence “behind the high-quality development of” big country heavy equipment “.
In the 2023 annual report, China National Heavy Truck Group ranks first in China’s heavy truck industry sales and market share, behind which is the return of scientific and technological innovation, but also a new performance of kinetic energy.The transformation and upgrading of new industrialization is an important topic of current economic development. Sinotruk attaches great importance to scientific and technological innovation, informatization integration, and new technology application, and promotes the transformation of traditional industries into intelligent and high-end directions.
On February 12, 2020, SinotruK’s “intelligent network connection (new energy) heavy truck project” (hereinafter referred to as the “Laiwu Factory”) broke ground, took 9 months, and achieved the first heavy truck off the line on November 18, from the ground breaking to the first heavy truck off the line only 280 days, creating an industry record of “the year started, the year put into production”. Thanks to digital and intelligent transformation and upgrading.
In the welding workshop of China National TruK Group Laiwu Factory, the scene of workers holding welding masks in one hand and welding guns in the other hand no longer exists, and robots in smart factories have completely replaced manual welding. A piece of steel plate into the welding workshop, out has become the “new Yellow River” heavy truck head.
“It takes about 3-4.5 seconds for a robot to weld a single spot, and there are 3,000 such spots in a locomotive. The whole workshop has 38 processes, from a part to a head, which can be completed in just two and a half hours.” The relevant person in charge told reporters, “welding workshop two production lines only need 5 workers to manage.”
At the same time, the welding workshop’s “smart brain” is also running, it is connected to the welding workshop’s central control system, in addition to controlling the robot, but also responsible for order distribution and quality monitoring and other work, a high degree of intelligence, can work continuously for about 20 hours.
According to the relevant person in charge, the intelligent manufacturing platform independently implemented by SinotruK Group can realize the pull production with order delivery as the main line through the process control of the six modules of planning, production, process, quality, anomaly and team, realize the comprehensive real-time data collection and monitoring of production equipment, and improve the cooperation degree and management transparency of the whole process of production. The unit production time of the vehicle is 9% faster, the order delivery cycle is 14% shorter, and the per capita production efficiency is 15% higher.
The cab is welded, and after painting, rinsing and other processes, it will be transported to the final assembly workshop and the chassis will be spliced. The heavy chassis can be transported by AGV trolley. “These cars can be said to be the busiest transport workers in the workshop, although it is small in size, but the load can reach nearly 10 tons, but also automated driving, automatic identification of the orientation route, and automatic emergency stop and avoid obstacles.” These cars can also be charged on the go, and they can be charged wirelessly with cables buried underground, which is very flexible.” Relevant person in charge said.
It is understood that China National Heavy Duty Truck Group attaches great importance to the production line process equipment capacity improvement. Through the introduction of new equipment, punching, welding, coating, and other process equipment has been comprehensively upgraded, constantly improve work efficiency, improve process methods, and improve product quality. In recent years, the application rate of advanced equipment such as robots, AGV and vision in the production line has exceeded 300%, and the number of one abortion line in the industry has reached 24, which has achieved cost reduction and efficiency increase while improving the efficiency of the production line and product consistency.
In the cab loading link, the worker master first accurately controls the cab loading position through the remote control, and then fasteners the connection points. The whole process is smooth and smooth. In the final assembly workshop, there are more than 300 processes, and each process can be completed within 5 minutes by relying on the tacit understanding and skilled cooperation between man and machine.
In addition, the plant also built the first intelligent flexible production line in China, which can realize the production of diesel, natural gas and hydrogen heavy trucks in the same production line.
It is understood that SinotruK Group makes full use of advanced information technology such as big data, artificial intelligence and industrial Internet, continuously promotes intelligent and efficient operation mode, constantly explores and practices the best integration path of new technology and industrialization, and provides higher quality and more intelligent products and services for business and customers. Fully promote and lead the new industrialization model of commercial vehicle equipment manufacturing.
