A sucker rod tong assembly for fastening together sucker rods to a rod coupling, where the assembly can include a two-stage mechanical drive mechanism. The first stage can connect an upper sucker rod to a lower sucker rod via a rod coupling. The first stage can be limited in mechanical ability to tighten the connection to a pre-set shoulder torque value. The second stage can then be hydraulically and mechanically sequenced, using a linear gear drive mechanism, to rotate a main tong pinion gear that can further rotate the sucker rod connection through a fixed circumferential displacement to a mechanical stop.

A uniquely designed torque wrench having a torque body, the torque body attached to a frictional squeezing clamp, and a lug socket which is rotationally connected to the frictional squeezing clamp. The frictional squeezing clamp entering a contracted stated during extension of a rod of a hydraulic cylinder, and entering an expanded state during the retraction of the rod of a hydraulic cylinder, the lug socket turning the wing nut of a hammer union.

A breakout wrench assembly for a drill rig includes two support shafts. Each of the two support shafts is configured to extend in a direction relative to a drill pipe on a drill rig. The breakout wrench assembly also includes a carrier coupled to the two support shafts. The carrier is movable linearly along the two support shafts. The breakout wrench assembly also includes a breakout wrench pivotally coupled to the carrier or to one of the two support shafts. The breakout wrench includes a first end coupled to the carrier or to one of the two support shafts, and a second, opposite end configured to engage the drill pipe.

An attachment that is configured for attachment to an arm of a piece of heavy construction equipment. The attachment is configured to rotate a section of pipe during break-out (i.e. disconnection or disassembly) from another section of pipe and/or make-up (i.e. connection or assembly) with another section of pipe. The attachment is configured to break the joint or torque the joint, unthread or thread pipe, and lift the pipe under the power of the heavy construction equipment.

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.

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.

A differential iron roughneck for making or breaking a pipe connection includes: at least one first gripping cylinder for delivering torque to a first pipe; at least one second gripping cylinder for delivering and receiving torque to and from a second pipe; and a differential gearbox including: a primary shaft delivering torque to the at least one first gripping cylinder; and a secondary shaft receiving torque from the at least one second gripping cylinder, where the primary shaft and the secondary shaft rotate at different speeds.

A system with a wrench coupled to a rig floor, and the wrench can include a plurality of grippers, a linkage mechanism that couples the plurality of grippers together, and a plurality of actuators coupled to the linkage mechanism, with the plurality of actuators used to apply a force to the linkage mechanism in opposite directions, and with the linkage mechanism configured to evenly distribute the force between the plurality of grippers. The wrench can support a torque wrench or a backup tong of an iron roughneck.

A uniquely designed torque wrench having a torque body, the torque body attached to a frictional squeezing clamp, and a lug socket which is rotationally connected to the frictional squeezing clamp. The frictional squeezing clamp entering a contracted stated during extension of a rod of a hydraulic cylinder, and entering an expanded state during the retraction of the rod of a hydraulic cylinder, the lug socket turning the wing nut of a hammer union.

An improved multi-bolt and nut torque wrench for installing and removing bolts or nuts from flanged joints or the like which includes a plurality of torque stations having a plurality of high torque wrenches for engaging the heads of the bolts or nuts during a high torque phase of removal or installation; a plurality of low-torque motors operatively engaged with the wrenches for rotating the bolts or nuts during the low torque phase of removal or installation; a source of hydraulic fluid for driving the low-torque motors during the low-torque phase, and driving the high-torque wrenches during the high torque phase; and a mechanism for switching between the two phases depending on the torque needed.
