Roadheader for underground mining is designed to support efficient excavation and drilling in narrow tunnels, small-section roadways, and challenging underground environments. The Small Tunneling Drilling Rig features a compact structure that helps improve mobility and access where working space is limited. Its practical design combines drilling performance, flexible operation, and intelligent control options to support different mining applications.
The rig is manufactured with careful attention to structural quality, component processing, assembly, and performance inspection. Advanced engineering and controlled production processes help maintain reliable operation and consistent quality. Its compact design can also simplify equipment movement between underground work areas.
For mining contractors and equipment distributors, flexible configurations can help match different project requirements. Contact the company to learn more about technical specifications, available options, customization, and professional support.
The small tunneling drill rig is 0.98 meters wide, compact and highly maneuverable, making it easy to transport between sites. It is ideal for tunneling in narrow underground spaces with small cross-sections and for mining thin ore bodies.
