Abstract: A spinner tool includes a plurality of rollers configured to rotate a tubular and a linkage assembly configured to move the rollers into and out of contact with the tubular. The tool further includes a carriage assembly configured to support the linkage assembly. The carriage assembly has a frame, a pair of carriage rollers positioned on opposite sides of the frame, and a pair of spring cylinders positioned on opposite sides of each carriage roller. The spring cylinders are coupled at one end to the carriage roller and at an opposite end to the frame to force the carriage assembly into a centered position.

Abstract: A wrench assembly comprising an upper clamp assembly, a lower clamp assembly coupled to the upper clamp assembly, and an alignment device disposed between the upper and lower clamp assemblies to allow the upper clamp assembly to move laterally relative to the lower clamp assembly when rotated relative to the lower clamp assembly.

Abstract: A spinner assembly including a jaw assembly having a first portion and a second portion, and a linkage assembly coupled to the first and second portions of the jaw assembly. The linkage assembly comprises a first bar coupled to a pivot point, a second bar coupled to the first bar by a first pin, a third bar coupled to the second bar by a second pin, and a pair of links coupled to the pivot point and the third bar. The linkage assembly is configured to move the first and second portions along a substantially linear plane.

Abstract: A wrench assembly comprising an upper clamp assembly, a lower clamp assembly coupled to the upper clamp assembly, an alignment device disposed between the upper and lower clamp assemblies to allow the upper clamp assembly to move laterally relative to the lower clamp assembly when rotated relative to the lower clamp assembly, and an eccentricity sensing mechanism coupled between the upper clamp assembly and the lower clamp assembly.

Abstract: A wrench assembly having an upper clamp assembly and a lower clamp assembly coupled to the upper clamp assembly, wherein the lower clamp assembly comprises a plurality of grippers each having a grip head configured to grip a tubular. Each grip head has a die plate surrounded by a primary contact plate. The primary contact plate is configured to contact the tubular prior to the die plate.
