The Epiroc Robbins 34RH C is a compact raiseboring rig with a modular design, purpose-built for precise operations in tight underground environments. Its low-profile frame suits small-diameter raises, slot drilling, backfilling, and boxhole applications.
Powered by a robust hydraulic system and the advanced Rig Control System (RCS), the 34RH C ensures accurate control of torque and thrust while enhancing safety and diagnostics. The patented rotation head and integrated worktable simplify handling of stabilizers and reamers. The rig accommodates both standard (720 mm) and wide (1,060 mm) frames.
Key Benefits
- Low-profile configuration ideal for restricted access areas
- Performs slot raises, backfilling, boxhole and reverse reaming
- Remote-controlled pipe handling and hydraulic wrench
- Precise force and torque control via RCS automation
- Modular frame for fast transport and setup
