The SBM 450 is a complete system for drilling long holes and boring raises as large as 7 ft (2.1 m) in diameter and 1,500 ft (457 m) in length. The system includes; a diesel operated crawler for transportation of the machine electric / hydraulic power pack with integral controls with a remote control station plus tools to make up or break out threaded pipe connections. In addition to its ability to pull raises the machine can also drill boxholes in serial up to 28 in (0.7 m) in diameter and 196 ft (60 m) in length. The 450 has a chute installed to protect the machine and to deflect the chips.
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 450 can be set for vertical drilling in a station height of only 13.3 ft (4.1 m).
