Description

Slot-Cutting Raise Boring Rig

The slot-cutting raise boring rig is an innovative underground excavation device that replaces traditional drill-and-blast slot cutting methods with mechanized technology. This equipment does not require the pre-casting of a concrete foundation and enables “work immediately upon arrival,” greatly improving construction convenience and efficiency. The slot-cutting raise boring rig is suitable for upward, downward, and multi-angle slot construction within the same section, offering outstanding advantages such as intelligence, environmental friendliness, and high operational efficiency, while also reducing auxiliary time for equipment transfer and transportation.

Features of Slot-Cutting Raise Boring Rig

  • Mechanized cutting, no need for concrete foundation, easy installation, and short construction cycles.
  • Supports multi-directional and multi-angle excavation, adapting to complex underground environments.
  • High safety performance, intelligent and highly automated operation, and environmentally friendly.
  • Also has the pilot hole enlargement function of conventional raise boring rigs, enabling multi-purpose use.
  • Optional tilt shaft drill rod tray and cable reel for inclined shaft operations to meet diverse construction needs.

Applications of Slot-Cutting Raise Boring Rig

  • Suitable for slot and raise construction in mines, tunnels, and other underground engineering projects.
  • Widely applicable to underground excavation projects requiring high efficiency, intelligence, and environmental protection.
  • Especially ideal for complex construction environments that require rapid transfer and multi-process switching.
