This cooperation marks the implementation of the national “Belt and Road” strategy by Tiejian Heavy Industry. Together with the world-famous engineering equipment company AMV, which is known as the “little giant” in the industry, it realizes industrial equipment “Internet +” through systematic planning of the Group's advantageous business. "Building an intelligent rock drilling rig, a high starting point into the global rock drilling equipment industry, opening a new chapter in the manufacturing field.
With the launch of the 2025 China Manufacturing Strategy, “Intelligent Manufacturing” has become the focus of attention in the industry. As an important manufacturing base in China, how can Changsha play a new advantage in the new normal and seize the commanding heights?
Innovation is an important force to promote the development of a country and a nation. With the development of science and technology to drive “manufacturing” to “intellectual creation”, Changsha has started a new operation. On August 28th, the reporter of Sanxiang Metropolis Daily went into the large-scale industrial enterprises such as China Railway Construction and Huaying Science and Technology with the large-scale report group of “Xiangjiang North” to explore the trajectory of “Intelligence” in Changsha.
Tiejian Heavy Industry A number of “intelligent” products fill the gap in the world
At 7:00 on the morning of August 28, Yang Jie came to the ground monitoring room of Xiangya Road Station of Changsha Metro Line 1. Every day he basically interacted with the display screen. The video, signal, data and parameters of the underground construction site were displayed in the display system. It’s all at a glance. This intelligent information monitoring system was built by Tiejian Heavy Industry for Changsha Metro. Tiejian Heavy Industry strives to integrate the intelligent manufacturing concept into all aspects of R&D, design, sales and post-service.
In the iron construction heavy industry factory, the reporter was shocked by a two-story "big guy". According to the on-site commentator, this is the world's first TBM tunneling machine for inclined wells in the world. It can be used for more than 30 meters and can dig 680 meters underground, which is equivalent to drilling a 230-storey large passage in the underground. “With this type of roadheader, it takes only three sets to build a mine, which can replace 300 laborers, and the efficiency can be increased by four times.” The commentator said that this technology creatively opened up the application of shields in the coal mine field and filled the gap. The world is blank.
In the tender for the Changsha subway shield machine, Tiejian Heavy Industry beat each of the 10 competitors including internationally renowned manufacturers at a price of about 5 million yuan cheaper than similar foreign products. The person in charge of Tiejian Heavy Industry revealed that at the beginning of the establishment of Tiejian Heavy Industry, he originally wanted to take the road of joint venture, but when they found that foreign companies did not want to cooperate with Chinese enterprises in the core technology field, they decided to conduct independent research and development.
At present, Tiejian Heavy Industry owns high-end shield products with completely independent intellectual property rights. In the past three years, it has occupied half of the domestically produced shields. It has the world's most advanced production line of ballast and spring fasteners, and many products of special engineering machinery have filled. Domestic and even the world is blank.
