Among the products exhibited by CRCHI were China's largest independently developed diameter shield tunneling machine "Jianghai", the country's first 16-meter-class ultra-large-diameter shield tunneling machine "Jinghua", the world's first pure electric plateau-type fully computerized three-boom rock drilling jumbo, and the disc cutter rock boring machine and other innovative products, demonstrating the company's latest achievements in high-quality development and representing the latest trends in the development of new quality productive forces in the industry.

CRCHI's tunnel boring machines include 9 major series and 195 products, mainly used for integrated excavation, boring and support construction of tunnels, roadways, shafts and inclined shafts, with excavation diameters ranging from 0.5 to 23 meters. Its R&D strength, market share of main products, full life-cycle service capability and brand influence are all in a leading position in the industry.

Guided by construction methods and aligned with the development goals of high-end, intelligent and green development, special equipment has achieved iterative upgrading of drill-and-blast tunnel equipment, with intelligent technology leading the industry. CRCHI proposed the world's first overall solution for pure electric tunnel construction equipment, filling a market gap.

The mining equipment bolter-miner series products continue to maintain a leading position in the industry. Building on the existing product spectrum focused on soft rock roadway excavation, CRCHI has developed new hard rock boring equipment such as the disc cutter rock boring machine and the disc-type rock boring machine, solving the challenges of hard rock and semi-coal rock excavation and leading the innovative development of intelligent equipment.

At this exhibition, the CRCHI booth not only showcased major national equipment but also presented digital product experiences full of technological content. The video "Journey to the Earth's Core Express: 'Steel Backbone' Deep Earth Roaming" uses AI to envision the future, revealing how the "resident courier" deep within the Earth continues the legend of human stories in deep underground space. The L-screen glasses-free 3D video and quad-screen displays vividly presented the stunning scenes of major national equipment serving major projects.
