The SBM 700 is a complete system for boring raises up to 12 ft (3.66 m) in diameter and up to 1,500 ft (457 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. Infinitely variable speed and constant torque of the hydraulic drive enable you to adjust the rotary speed to exactly mach your drilling conditions. Shifting is done hydraulically for smoothly changing from high-speed range for pilot hole drilling or into the low-speed range for reaming. The SBM 700 can be set for vertical drilling in a station height of only 13 ft (4 m).
