The SBM 300 is a complete system for boring raises up to 39 in (1 m) in diameter and up to 1,000 ft (300 m) in length. The system includes an electric / hydraulic power pack with integral control station and tools required to make or break threaded pipe connections. Self-propelled crawlers for machine transport are also available.
Infinitely variable speed and constant torque of the hydraulic drive enable you to adjust rotary seed to exactly mach your drilling conditions. Shifting is done hydraulically for smoothly changing from high-speed range for pilot hold drilling or into the low-speed range for reaming. With the SBM 300's extremely low profile you can set for vertical drilling in a station height of only 9.5 ft (2.9 m).
