ABSTRACT:
A pipe racking system is shown of the type having a vertical track, a lifting assembly adapted for vertical movement along the track, a horizontal beam for supporting the vertical track, and a movable carriage connecting the vertical track to the horizontal beam. The lifting assembly is supported by a wire rope running from the lifting assembly inside the vertical track and outside the carriage to a source of lifting power. A fixed guide sheave mounted in the carriage serves as a first point of contact for the wire rope running from the lifting head to the carriage. A rotatable guide sheave mounted in the carriage serves as a second point of contact for the wire rope. The rotatable guide sheave is rotatable by the wire rope in response to movement of the carriage, vertical track, and horizontal beam to center the wire rope in the guide wheel grooves of the guide sheaves during racking operations.
