ABSTRACT:
The present invention provides a bolt delivery system having a bolt magazine movably attached to a magazine base which in turn is affixed to a rock bolter having a bolt driver. The bolt magazine moves between a work position and a park position. In its work position, a linear incremental bolt advancing mechanism advances the bolts to where they are aligned with the bolt driver, and, in combination with a bolt-embracing arm, maintains the aligned bolt until it is engaged by the bolt driver. After the bolt driver has engaged the bolt and advanced it to engage a bolt centralizer provided to position the bolt in a pre-drilled hole in a rock surface, the bolt magazine is moved to its park position. At which time, the bolt driver is further advanced driving the bolt into the pre-drilled hole. The linear incremental bolt advancing mechanism preferably has a lower and an upper bolt advancing mechanism, and more preferably, provides the bolts a component of motion toward the rock surface. Preferably, the bolt delivery system also delivers bolt plates.
