Patent ID: 7191686

Claim:
An apparatus for connecting or disconnecting threaded tubulars, comprising: a pair of arms pivotably coupled at a distal end; a first displacer secured to the pair of arms for selectively moving a proximal region of the pair of arms into an open position for receiving or withdrawing a tubular and into a closed position for engaging and rotating a tubular; three or more rollers rotationally secured to the proximal region of the pair of arms with at least one roller secured to each arm, the rollers collectively adapted for spanning at least 180 degrees of the circumference of a tubular received and engaged between the arms in the closed position, wherein at least one of the rollers is a drive roller for spinning a tubular; two or more jaws secured to the proximal region of the pair of arms with at least one jaw secured to each arm, the jaws collectively spanning at least 180 degrees of the tubular circumference for selectively gripping a tubular with the arms in the closed position; and a second displacer secured between the distal end of the pair of arms and a fixed structure, wherein the fixed structure is positioned so that actuating the second displacer applies a generally tangential force for applying a final torque value to a tubular gripped by the jaws.
