AT-4000L Raise Boring Machine

The AT-4000L Raise Boring Machine was developed to meet the evolving requirements of modern underground mining operations. Based on optimized rock-drilling parameters and an integrated system design, the machine features a more compact configuration and reduced overall height. Its integrated crawler travel system enables convenient relocation and improves maneuverability in confined underground tunnel environments.

AT-3000L Raise Boring Machine

The AT-3000L Raise-Boring Machine is a new-generation compact crawler-type mobile drilling equipment for modern underground mines. With an articulated chassis, intelligent PLC control system and dual wired/wireless operation modes, it achieves excellent manoeuvrability and high safety in narrow roadways. Featuring foundation-free installation, intelligent multi-protection system and high drilling accuracy within 0.5% deviation, the machine ensures efficient, stable and reliable raise-boring construction for various underground mining projects.

AT‑2000T Mini Raise‑Boring Machine

The AT‑2000T Mini Raise‑Boring Machine is a compact raise‑boring unit built for small‑to‑medium underground mines with narrow transport passages, limited working space and low‑clearance conditions. Its modular design offers two travel options: tire‑based self‑propulsion and rail‑guided towing.It integrates the drilling assembly and travel chassis into one compact, remotely‑controlled unit. This simplifies site‑to‑site relocation and minimizes repeated disassembly and reassembly. Thanks to its flexible positioning system and quick‑disconnect structure, setup and relocation can be completed efficiently. The AT‑2000T is well suited for underground raise construction where space and transport conditions are constrained.

AT-2000 Raise Boring Machine

The rail‑mounted raise‑boring machine features full mechanization and remote‑control operation. Equipped with roller‑cone cutters and high‑strength DI‑22 threaded drill rods, it delivers high drilling efficiency with low deviation. Installation is fast and foundation‑free for depths under 100 m. It supports 0.9‑2.4 m boreholes down to 280 m, widely applicable to mining, hydropower, metro, civil defence and other underground shaft‑construction projects
