ABSTRACT:
A rod storage and transport apparatus comprising a roof bolter including a tool. The apparatus includes a rotatable holding carousel adjacent the tool and adapted to hold a plurality of rods therein. The apparatus also includes an extending and retracting transport mechanism cooperating with the carousel to move one rod at a time between the carousel and the tool, so that the tool can use the one rod to perform a mine operation. The carousel has a generally elongated shape and is able to rotate about a longitudinal axis of the shape. This permits the carousel to position the one rod held by the carousel adjacent the transport mechanism, so that the transport mechanism can transport the one rod to the tool, or position the carousel to receive a rod transported by the transport mechanism from the tool. The transport mechanism when fully retracted is substantially within a cylinder generated by the rotation of one of the rods about the longitudinal axis of the carousel.
