<p>POWERED PIPE WRENCH TYPE TOOL A lightweight, portable, powered pipe wrench type tool (10) for loosening or tightening threaded pipe members includes a pair of wrenches (16) and (18) having jaws (26) and (30) and elongated handles (22). Each handle (22) includes an inward section (46) and an outward section (48) interconnected by a joint assembly (50) whereby the handle sections may be positioned in selective, angular orientations relative to each other. A linear actuator (24) that laterally spans handle outward sections (48) is extendable to rotate the wrenches (16) and (18) relative to each other to loosen or tighten pipe members depending on the orientation of the wrenches relative to the pipe members.</p> |
