2025 Epiroc Raiseboring equipment Robbins 44RH

Low profile and lightweight raiseboring machine for both civil engineering and mining applications.

Its compact design offers greater maneuverability without sacrificing high torque and thrust.

Features may include:

Lightweight boring machine
  • Robbins 44RH is a low profile and lightweight raiseboring machine for holes ranging from 1.0 to 1.8 m (3.5-6 ft.) in diameter. The rig has been optimized for low ceilings and holes up to 1.8 meters in diameter. With a height of only 3.25 m, the low-profile Robbins 44RH is designed to provide immense penetrating power in constricted work spaces. Its compact design offers greater maneuverability without sacrificing high torque and thrust. Robbins 44RH can be relied on to drill holes with greater power and efficiency.
