    摘要: An automated pipe racking apparatus for a drilling rig having an elevator suspended over a well bore. An arm support member is rotatable about an axis parallel to the well bore. A gripper arm extends from the arm support member along an axis normal to the axis of rotation of the arm support member. A gripper head assembly extends from the gripper arm, the gripper head assembly having a pair of opposed, arcuate gripper fingers, each said finger rotatable by a motor.
