Abstract
A tool base securing system for a rock bolter. One aspect of the invention provides a securing system for the tool base which is being advanced on a cradle along a feed shell. This system includes a forward latch which is pivotably attached to the forward section of the cradle base and has a tool base engaging lug. A mechanical linkage is provided to engage and disengage the front lug from the tool base as the cradle is advanced from and returned to a park position on the feed shell. In a preferred embodiment a rear latch is also provided which has a mechanical linkage for engaging and disengaging a rear lug. A second aspect of the invention provides a securing system which provides a mechanical interlock which immobilizes all tool bases which are off the cradle when the cradle is being advanced.
