Abstract
A pipe handling apparatus for moving a pipe from a stowed position to a position deployed above a wellhead has a main rotating structural member pivotally movable between a first position and a second position, an arm interconnected to the main rotating structural member, a gripper affixed to an end of the arm opposite the main rotating structural member, and a tensioner connected to the gripper for applying a tension to the gripper when the arm is in the extended position. The gripper grips a surface of a pipe. The arm is pivotable between a home position and an extended position. The tensioning means has a guy wire connected at one end to the gripper. The guy wire has an opposite end connected to the arm. Alternatively, the opposite end is connected to the main rotating structural member.
