SPM-J45 series hydraulic drilling jumbo is a type of tunneling equipment suitable for various metal mines, tunnels and underground passageways. It is a single-boom machine that uses an advanced hydraulic rock drilling system paired with an anti-jamming device to ensure fast drilling speed and high work efficiency. This drill rig possesses the qualities of high flexibility, small turning radius and superb gradeability. It will help to greatly improve the work environment and also increase the efficiency and quality of the construction project.
SPM-J series suitable to work for rock hardness f=6-16 or higher. Since it equips a drifter from Epiroc and Montabert France, and a boom with wider swing and tilting angle, the jumbo has a larger coverage when jacked. The jumbo's feed can rotary 360° both in horizontal and vertical directions, that makes a fast and quality tunneling can be guaranteed. It is also have drilling function for crossdrift and bolting holes in the meantime.

The drilling jumbo is featured by compact structure and great mobility. large quantities of dust will be produced during drilling. SPM-J series adopts efficient dust control measure. The water is used for hole flushing during rock drilling, minizing dust generation. This provides a comfortable and safe working environment.
