Abstract: An elongated, hollow spool has end flanges and a recessed section between the end flanges. The spool may be attached to an flange atop a tubular member, and other equipment may be attached to the top of the spool. A pull collar, typically of two substantially identical half circle pieces, fits around the intermediate section and is pinned together. The collar can then rotate around the spool, but is longitudinally restrained. Attachment lugs formed in the collar permit attachment of securing members, to run to anchor points, or to fasten to other equipment to stabilize same.

Abstract: A power swivel stand for horizontally and vertically positioning a power swivel with respect to a well being serviced. A frame is mounted on a base, preferably by pinned connections. A carriage is mounted in the frame and is vertically positioned by one or more hydraulic cylinders. Attached to the carriage are one or more positioning arms, in such a manner that the positioning arms can be pivoted in a vertical plane. The positioning arms can be pivoted by extension and retraction of hydraulic cylinders connecting the carriage and the positioning arms. A power swivel is held by the positioning arms. Pivoting the positioning arms moves the power swivel horizontally into and out of alignment with the well being serviced.
