Abstract
A system includes a top drive system equipped with a mounted winch configured to draw tubular or well equipment into alignment with a quill of the top drive system. The winch comprises a spool and a flexible line that extends from the spool and through channels in the top drive system, exiting through the quill. An attachment feature at the distal end of the flexible line couples the flexible line with the tubular or drilling equipment. Once this coupling has been established, the winch may rotate such that the flexible line retracts through the quill of the top drive system, drawing the tubular or well equipment into alignment with the quill.
