Designed to meet the specific requirements of the China-Kyrgyzstan-Uzbekistan Railway tunnel project, this high-capacity arch assembly machine features a minimum excavation clearance section of 5 meters (width) × 6 meters (height). Unlike standard arch installation trolleys that typically operate in larger tunnel sections, this specialized equipment is engineered for single-track tunnel applications.

• Articulated chassis structure with small turning radius for enhanced maneuverability in confined spaces
• Compact overall height of 3.7 meters ensures compatibility with secondary lining trolleys
• Modified boom structure specifically designed for China-Kyrgyzstan-Uzbekistan railway tunnel specifications
• Requires secondary lining trolley height ≥4.2 meters when utilizing back arch function
• Capable of self-transporting multiple Unit A arches

The improved KGM12300 model meets the minimum section requirement of 5m (width) × 6m (height) for vertical arch operations. Two construction solutions are available for selection based on actual site conditions of the China-Kyrgyzstan-Uzbekistan railway tunnel project.
