摘要： A system for screwing together threaded connections includes a pair of moveable arms which first grip the tubular to provide a contact force against three hydraulically powered drive rollers, 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 (three) which extend radially inwardly to grip the tubular, so the connection can be made up to final torque by contracting a hydraulic cylinder. The hydraulic cylinder that is used to apply the final torque value is attached on one end, where the moveable arms are pinned together, and on the other end to something fixed, such a snub post or derrick leg. Rotation of the opposing connection is prevented by the use of standard equipment such as a manual chain tong.
