Patent 10309169 was granted and assigned to Drillform Technical Services Ltd. on June, 2019 by the United States Patent and Trademark Office.
A spinner wrench for use on a drilling rig is provided. In some embodiments, the wrench can comprise three or more spinning rollers that can be disposed around a tubular. The three or more rollers can be connected to three or more hydraulic rams. In some embodiments, each ram can be connected to a single roller and the axis of the ram can be in a plane perpendicular to the pipe axis but not intersecting the pipe axis. For improved performance during make-up, in planar view, each ram axis can be offset to a counterclockwise direction around the drill pipe axis. For improved performance during break-out, in planar view, each ram axis can be offset to the clockwise direction. In some embodiments, the three or more rollers can be disposed around the drilling pipe or other tubular by a main body and one or more latching bodies.
