Abstract
Embodiments of the present disclosure relate to a wrench for loosening or tightening a threaded joint of two drill-string components. The wrench is mountable on a drill assembly. The wrench comprises: a jaw assembly with opposing jaws for engaging the drill-string component therebetween; a first actuator for actuating the pair of opposing jaws between an engaged position and a disengaged position; a second actuator configured to pivot the jaw assembly and configured for applying a torque when engaged with the drill-string component; a third actuator configured to extend and retract the jaw assembly in a first plane substantially perpendicular to the longitudinal axis of the drill assembly when the wrench is mounted on the drill assembly; and a fourth actuator for actuating the wrench in a second plane substantially perpendicular to the first plane. Embodiments of the present disclosure also relate to drilling systems comprising the wrench.
