Abstract
A rock bolter has a turret assembly having a positionable base. The base slidably and rotatably engages a cylindrical member on which a feed track support is affixed. A jack rotatably and slidably engages the cylindrical member, but cannot translate with respect to the base. The jack has a piston connected to the feed track support, and extending or retracting the piston translates the cylindrical member relative to the base to move the feed track support toward and away from a rock surface. A stinger assembly connected to the base engages the rock surface to stabilize the turret assembly. A pivot actuator connected between the base and the jack rotates the jack and the feed track support to selectively place either a drill or a bolt driver in alignment with a desired location on the rock surface.
