It is equipped with the HLX5 hydraulic rock drill, LHF2000 feed, ERCH12 rod handler, SB60P boom, THC560 hydraulic control system and operator's safety cabin for maximum productivity, safety and hole accuracy. The 360° drilling module rotation and wide boom swing and tilt angles make the unit suitable for most mining methods and various service support applications. The THC560 drilling control system is fitted with automatic features for maximum productivity in varying rock conditions, in up- and downhole drilling.

The layout of the NC5 carrier is designed for good visibility and stability, ensuring safe tramming in narrow mine drifts. The operating and maintenance interface are designed for easy access, safe operation and all service points are accessible from the ground level.
