    Patent number: 7744327
    Abstract: The invention relates to a tubular handling apparatus for moving tubulars between a substantially horizontal transfer station and a second transfer station. The apparatus comprises a base and a boom, rotatable with respect to the base between a lowered position and a raised position by boom rotation drive means in a boom rotation direction around a horizontal boom rotation axis. Furthermore, the apparatus comprises a gripper, rotatably attached to the boom and adapted for gripping the tubular, which gripper is rotatable about a gripper rotation axis by a gripper rotation drive means in a gripper rotation direction.
