The Secretary of Xin Changxing summed up the achievements of the province's scientific and technological development in recent years.，Taking stock of a series of major achievements。It mentionsThe world's largest tonnage cantilever tunnel boring machineFrom Xugong Group，Can realize one-time excavation and formation of medium and large-section tunnel，It is mainly used for highway、Construction of railway and other large-section tunnels and mine roadways，It marks that China has reached the world's leading level in the field of cantilever tunnel boring machines.。

XCMG is the first manufacturer to develop tunnel boring machine in China.，The technical challenges and research and development difficulties can be imagined.。XCMG Foundation led the creation ofMultiple dimensions、OpenA group of technical experts，Combined with international advanced technology and years of tunnel construction experience，Break through a number of key core technologies，Develop new products with independent intellectual property rights——XugongXTR7/360 cantilever tunnel boring machine，Break the monopoly of foreign technology，It has been widely used in hard rock engineering.，And on this basis, improve the construction capacity.，Develop a performance improvementXugongXTR8/500 cantilever tunnel boring machine。

XugongXTR8/The 500 cantilever tunnel boring machine isSet cutting、Walk、Shipment、Cable winding and other functions are integrated.Rock heading equipment，The weight of the fuselage is 218t，It is the largest tonnage cantilever tunnel boring machine in the world.。Cutting power 500kW, The cutting speed can be adjusted according to the rock conditions.，It is the world's largest cantilever tunnel boring machine.。

September 2022，XCMG Tunnel Boring Machine Hit CCTVCCTV-9 large-scale documentary films《Super equipment》。At the Dalian Bay Subsea Tunnel，XCMG roadheader“Roar and roar”，Incarnation“Steel behemoth”，The pick made its teeth and thundered toward the rock wall.。By means of a cutting head fitted with sharp cutting teeth，Easy to deal with strong pressure resistanceHard rock with a temperature of about 100 MPa，Continuous attack“Jian”Overcome difficulties、Dare to touch“Hard”。

Behind the Heavy Weapons of Great Powers，It is a technical research that has been sharpened for ten years.，It is persistent innovative research and development.。Every scientific and technological innovation achievement，It marks an important milestone for Xugong on the road of tackling key technical problems.。By continuing to increase investment in research and development，Xugong has not only made breakthroughs in product performance and technical level.，More energy saving and environmental protection、Intelligent manufacturing and other leading industries，Showed to the world“Made in China”Unique charm。
