The Boomer E3 C is a modern, hydraulic face drilling rig suitable for large sized tunnels with cross sections up to 137 m2. The drilling is controlled by the computerized, award-winning Rig Control System (RCS 5) with an intelligent functionality that ensures precision, productivity, increased uptime and lower costs. The rig is equipped with three robust and flexible BUT 45 booms and COP 3038 rock drills for maximized productivity.

Features & benefits

  • RCS 5 handles positioning and drilling for high precision and productivity, offering several levels of automation to suit your requirements.
  • Low-emission diesel engine combines low environmental impact with powerful performance.
  • BUT 45 heavy-duty booms mean direct, fast and accurate positioning. Excellent reach and flexibility are provided by a 2500 mm feed extension and double rotation units with ±190 degrees feed rollover and ±135 degrees feed rotation.
  • COP 3038 rock drills ensure true high-speed drilling. The dual-damping system minimizes wear for longer consumable life.
  • To ensure operator safety and ergonomics, the Boomer E3 C is endowed with a safe and comfortable cabin as standard.
