Abstract

A drill head assembly for receiving a drill rod in an operative position. The drill head assembly has a chuck and cradle configured for movement between a first position and a second position. In the first position, the longitudinal axis of the chuck is substantially parallel to the longitudinal axis of a drill mast. In the second position, the longitudinal axis of the chuck is substantially perpendicular to the longitudinal axis of the drill mast. From the first position, the cradle is configured for sequential axial and then pivotal movement relative to the transverse axis to reach the second position, with pivotal movement being restricted until axial movement is completed. Drill rod handling systems having such drill head assemblies, and methods of using such drill head assemblies, are also disclosed.
