Apparatus and methods for moving a tubular member to and from an elevated drilling rig floor. In one embodiment, the apparatus comprises a support structure configured to be positioned adjacent a pipe rack. A carrier is moveably coupled to the support structure, and a carriage is moveably coupled to the carrier. A trough extends longitudinally over the support structure and is moveably coupled to the carriage, the trough being configured to receive a tubular member. The trough is operable to tilt relative to the support structure. A lift arm is operable to move the carriage relative to the support structure thereby also moving the tubular member received in the trough. Indexers may urge the tubular member toward or away from the trough. Pick up arms are operable to retrieve a tubular member from an adjacent pipe rack, or to place the tubular there for storage. |
