People's Daily and Economic Daily both praise Jinan Heavy Industry: old state-owned enterprises are revitalized with new vitality
After the Economic Daily reported on Jinan Heavy Industry Group on its front page on May 13th with the title "New Vitality of Old State Owned Enterprises", the People's Daily published on May 14th once again focused on Jinan Heavy Industry Group Co., Ltd. in its second edition with the title "New Vitality of Old State Owned Enterprises" in the form of image news.
The "Jinan made" shield tunneling machine has left Jinan and entered the national market. Why did Jinan Heavy Industry produce shield tunneling machines? The reporter learned that as early as 2009, Jinan Heavy Industry had already started to organize data and technical reserves for shield tunneling machines when Jinan planned the "Yellow River Tunnel".
The picture shows workers recently inspecting the cutterhead of a shield tunneling machine that is about to be completed.
Jinan Heavy Industry Group Co., Ltd., which has provided equipment support for subway construction in multiple cities such as Jinan, Fuzhou, Beijing, and Hangzhou, was founded in 1949. In recent years, the company has continuously increased its R&D investment and is building an intelligent manufacturing and high-end equipment industrial park with the rail transit equipment industry as its core. The focus is on developing product areas such as full section tunnel boring machines and prefabricated building materials production lines, and the old state-owned enterprise is shining with vitality.
On May 13th, the front page of the Economic Daily reported on Jinan Heavy Industry Group under the title "Revitalizing Old State owned Enterprises", stating that the "Jinan Made" shield tunneling machine has gone to more than 40 countries and regions around the world. Why did Jinan Heavy Industry produce shield tunneling machines? The reporter learned that as early as 2009, Jinan Heavy Industry had already started to organize data and technical reserves for shield tunneling machines when Jinan planned the "Yellow River Tunnel".
Economic Daily praises' Made in Jinan 'as it goes global
On May 11th, workers walked past a shield machine that was about to go offline in the production workshop of Jinan Heavy Industry Group Co., Ltd. Jinan Heavy Industry Group Co., Ltd., founded in 1949, provides equipment support for subway construction in multiple cities. The company's products are sold to more than 40 countries and regions including Japan, the United States, France, and Germany.
At present, the company is committed to building an intelligent manufacturing and high-end equipment industrial park, focusing on the development of full section tunnel boring machines, tunnel boring specialized equipment, prefabricated building materials production lines and other product fields, revitalizing the old state-owned enterprise.
Why is Jinan heavy industry to build the shield machine?
With the rapid development of rail transit in Jinan, the demand for shield machines has ushered in a "blowout", which brings opportunities for the development of rail transit industry. As far as Jinan is concerned, most of the cities in the economic circle of the provincial capital city group have the potential to develop rail transit. Jinan's rail equipment industry is complete, which is also a great benefit for these cities to start subway projects. Because the shield machine equipment is too large to be transported as a whole, it is also very troublesome to assemble and transport, and the manufacturing plant can only be within 100 or 200 kilometers from the construction site.
And Jinan heavy industry involved in the shield machine industry "second venture" is not accidental, but has the right time, right place, with right people. factors. Among them, the driving force for the development of new projects also comes from the core technology and R & D team that Jinan Heavy Industry has never abandoned. "Before the production of shield machines, our company's desulfurization (products accounted for more than 60% of the domestic market, and the peak period accounted for more than 75% of the domestic market." Shi Junfeng, head of the marketing department and senior engineer of Jinan Heavy Industry, told reporters that desulfurization (mainly used to crush limestone and add water to reduce sulfur dioxide emissions from power plants. The cylinder body is similar to the shield body of the shield machine and is welded with steel plates. In order not to leak lime slurry at the feed port of the machine, they only developed a sealed pump and obtained 5 patents. Similarly, in solving the problem that the temperature of the machine bearing is easy to damage when the temperature exceeds 65 ℃, they have improved the process to increase the life of the bearing to 10 years.
Five cities have already used shield machines "made in Jinan"
The reporter learned that as early as 2009, when Jinan planned the "Yellow Tunnel", Jinan Heavy Industry had already begun to organize the data and technical reserves of the shield machine. In recent years, Jinan Heavy Industry has conducted technical exchanges with many companies such as Herrenknecht in Germany, Komatsu in Japan, Kawasaki, etc., and has produced a large number of shield machine parts for Herrenknecht in Germany and China Shipbuilding Industry Corporation, and has accumulated rich design and manufacturing experience.
As of 2018, Jinan Heavy Industry has successfully rolled off the production line and applied 36 shield machines in the Jinan Metro project for the construction of Jinan Rail Transit Line 1, and promoted the application to Guangzhou, Hangzhou, Fuzhou, Beijing and other places.
It is reported that the predecessor of Jinan Heavy Industry is Jinan Heavy Machinery Factory. It was established in 1949. The company has strong technical development capabilities and manufacturing capabilities. It has provided a large number of advanced equipment for China's tunnel construction, electric power, mining, petroleum and other industries. The market share of coal mills ranks first in China, and large-scale cement equipment and large-scale seamless steel pipe production line equipment have a leading level in China.
