Pipe handling for a drill string at ground exit
An exit side pipe handling and vise tool. The tool may be suspended from an arm of a hydraulic machine and rotated and pivoted relative to the arm. The tool comprises two retainer assemblies, two vise assemblies, and a roller assembly each suspended from a linear frame. Each of the retainer assemblies is movable relative to the frame in a direction transverse to a length of the frame. The vise assemblies are in side-by-side configuration to break a connection between adjacent pipe segments. The roller assembly defines rollers having a spiral ramp disposed on an external surface to encourage axial movement of a pipe segment during rotation thereof.
