A system (10) for screwing together threaded connections includes a pair of moveable arms (10) which first grip the tubular (12) to provide a contact force against three hydraulically powered drive rollers (26), that are contained within the arms. The three drive rollers will screw or "spin" the connection to an initial torque value. The moveable arms also contain a set of jaws (28) (three) which extend radially inwardly to grip the tubular, so the connection can be made up to final torque by contracting a hydraulic cylinder (34). The hydraulic cylinder that is used to apply the final torque value is attached on one end (32), where the moveable arms are pinned together, and on the other end to something fixed, such a snub post or derrick leg (36). Rotation of the opposing connection is prevented by the use of standard equipment such as a manual chain tong (40).

Système (10) pour visser ensemble des connexions filetées, comprenant une paire de bras mobiles (10) qui premièrement serrent le tubulaire (12) pour créer une force de contact contre trois rouleaux d'entraînement (26) actionnés hydrauliquement, contenus dans les bras. Les trois rouleaux d'entraînement vissent ou "font tourner" la connexion jusqu'à une valeur initiale de couple. Les bras mobiles comprennent encore un jeu de mâchoires (28) (trois) qui s'étendent radialement vers l'intérieur pour serrer le tubulaire, afin que la connexion puisse être réalisée jusqu'au couple final par contraction d'un vérin hydraulique (34). Le vérin hydraulique utilisé pour appliquer la valeur finale de couple est fixé à une extrémité (32), là où les bras mobiles sont goupillés ensemble, et à l'autre extrémité à quelque chose de fixe, tel qu'un poteau retroussé ou un pied de derrick (36). La rotation de la connexion opposée est empêchée par l'utilisation d'équipement standard, tel qu'une pince manuelle à chaîne (40).
