Abstract (en)
1. A bolting device comprising a movable support (5) supporting a drilling system (2), a system (8) for injecting the sealing charges and a system for inserting and tightening the bolts (11), and these systems (2, 8, 11) may be located in succession in the operating position in the axis of the drilling hole, characterized in that the movable support (5) is displaced in a straight line along an axis in order to bring the different systems (2, 8, 11) into position in succession and in that the axis of each of the above systems is perpendicular to the axis of displacement of the movable support (5).
