Break through“Stuck in the neck”Key technologies，Realization of Localization of Main Bearing of Roadheader

The main bearing is referred to in the industry as a roadheader“ Heart ”，It is the only part of the whole tunneling equipment that cannot be replaced during service.。Because of the material、Design、Manufacturing and testing are extremely difficult.，Foreign countries monopolize it for a long time.，Not only is the price up to tens of millions of yuan,，Technology、Production and services are often controlled by others.。

To break foreign monopolies，China Railway Construction Heavy Industry Co., Ltd. set up a research and development team，Carry out independent research on main bearings，Hundreds of materials and processes have been tried，Tens of thousands of sets of data were analyzed，Many difficulties have been overcome.，So that that main bear can bear the pressure of ten thousand tons、Scroll the target for more than 10,000 hours.。

China Railway Construction Heavy Industry Co., Ltd. independently developed the world's largest diameter、The monomer is the heaviest、Main bearing of integral shield machine with the highest bearing capacity（φ8.61 meters）

The Second Industrial Park of Changsha Railway Construction Heavy Industry has been built into the largest industrial park in China.、International leading shield machine main bearing production line，Has been successfully developed 3 meters to 7..6m full range of main bearings，The world's largest main bearing working condition simulation test bed has been built.，It solves the worldwide problem that large low-speed and heavy-duty main bearings are difficult to test and verify.。October 12, 2023，With 8.The main bearing of the 61-meter domestic super-large diameter shield machine rolled off the production line smoothly，Tiejian Heavy Industry has thoroughly conquered and independently mastered the design of the whole series of main bearings of shield machines.、Material to manufacturing、Key core technologies in the whole test process，So that the domestic shield machine has a full range of China“Heart”。

Next step，The company will continue to improve the innovation linkage mechanism.，Strengthen the integration of resources，Promote technology enabling high-end equipment“The amount of intelligence”“Green content”“Gold content”，High-quality development of high-end equipment industry in China，Make new and greater contributions to Chinese-style modernization。
