Abstract
A rod handler apparatus for outer tubes and inner tubes, the rod handler apparatus has a manipulator arm adapted to be aligned with an elongated rod. An alignment jaw assembly is at a first end of the manipulator arm, the alignment jaw assembly translationally supports an inner tube and/or an outer tube in coaxial alignment with the elongated rod. A high-speed jaw assembly is at a second end of the manipulator arm, the high-speed jaw assembly adapted to support at least the inner tube, the high-speed jaw assembly operable to cause a translation of the inner tube in or out of the elongated rod. A low-speed jaw assembly is between the alignment jaw assembly and the high-speed jaw assembly, the low-speed jaw assembly adapted to support the outer tube, the low-speed jaw assembly operable to cause concurrent translation and rotation of the outer tube for screwing engagement with the elongated rod.
