Abstract (en)
[origin: WO9521985A1] A drilling support unit for drilling holes in rocks is disclosed. A drive, in particular a hydraulic hammer, is guided in the drilling direction by a guide. The support unit is swivellingly mounted on a movable transport device. A hinge is provided between the transport device and the swivelling attachment of the support unit. The hinge (8) is designed for rolling over 360 DEG , so that it may be mounted on the coupling (1) of an excavator boom. The swivelling attachment (2) of the support unit is mounted on the side of the roll-over hinge away from the coupling (1).
