An attachment is described that is configured for attachment to an arm of a piece of heavy construction equipment. The attachment is configured to rotate a section of pipe during break out (i.e. disconnection or disassembly) from another section of pipe and/or make up (i.e. connection or assembly) with another section of pipe. The attachment is configured to break the joint or torque the joint to a predetermined torque value, unthread or thread pipe, and lift the pipe under the power of the heavy construction equipment.

A gearbox for a roller in a spinner wrench is provided. In some embodiments, the gearbox can be disposed internally to the roller and can include a sun and planet type epicyclical gear-reduction assembly. In further embodiments, the gearbox can include a second sun and planet type epicyclical gear-reduction assembly to provide for a second, or final, stage reduction. Some embodiments can provide for reduction-ratios close to 3:1 and can be driven by a relatively small motor. The planet gears can be used to drive an annular gear which can spin the roller. In some embodiments, the gearbox can use high-capacity bearings.

A self-adjusting spinner is provided that is capable of accommodating various pipe sizes without requiring the need for an operator to climb up the support mechanism and manually change the position of the drive assembly. The self-adjusting spinner includes a case having two pivotally connected members: a stationary case member and a moving case member. Upper and lower plates having gear racks are mounted on the stationary case member for moving a drive assembly horizontally across the case. The drive assembly includes a motor that drives gear sprocket through a drive shaft. The drive sprocket then drives a chain that rotates a drill pipe in an operative position relative to the case. The spinner also includes an adjusting assembly mounted on the case that moves the drive assembly along the gear rack upon the actuation of an adjustment sequence. When the adjustment sequence is initiated, the effective length of the chain is adjusted to accommodate drill pipes of varying diameters.

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.

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.

A tool for making up and breaking out a drill string at an exit side of a bore. The tool includes a fixed vise and a moveable vise for torqueing a pipe joint, a roller assembly for threading and unthreading adjacent sections of pipe, and a retainer assembly to retain a detached pipe section. The components of the tool are mounted on a frame, which is pivotally connected to a hydraulic machine such as an excavator. Thus, the tool may be manipulated to remove and add sections of pipe to a drill string remote from the primary horizontal directional drill.

A system, including one or more supports. The system also includes a movable platform slidingly coupled to the one or more supports and configured to be selectively moved towards a drill floor and away from the drill floor. The system further includes a roughneck disposed on the movable platform and configured to make up or break out a threaded joint between a first tubular segment and a second tubular segment, wherein the roughneck is configured to be selectively movable along the movable platform from a first position disposed adjacent to the one or more supports and a second position disposed adjacent to the first tubular segment and the second tubular segment.

A system for use in a mineral extraction system includes a spinner assembly having a motor configured to drive rotation of a roller shaft. The spinner assembly also includes a roller non-rotatably coupled to the roller shaft and configured to contact a first tubular structure, and rotation of the roller is configured to cause rotation of the first tubular structure until the first tubular structure is spun into a second tubular structure. The spinner assembly further includes a detection wheel coupled to the roller shaft and configured to contact the first tubular structure, and the detection wheel is configured to rotate with the first tubular structure and to rotate independently of the roller. The spinner assembly further includes a sensor configured to detect rotation of the detection wheel.
