Abstract
A blast hole drill with a drill head mounted on a mast has a pipe carousel on the drill deck which holds drill pipe along the length of the deck. A pipe handling arm mechanism has a lower arm portion pivotally mounted on the deck and an upper arm portion pivotally mounted to the lower arm portion. The upper arm portion has jaws that grasp a drill pipe. A ram connected to the upper arm portion pivots the arm mechanism until the lower arm portion engages a stop adjacent the mast. The ram thereafter continues to pivot the upper arm portion until a drill pipe carried thereby is aligned on the mast.
