Abstract
A pipe handling apparatus has a frame, a boom pivotally connected to the frame so as to be movable between a first position and a second position, an arm extending outwardly of the boom when the boom is in the second position, a gripper affixed to the end of the arm opposite the boom, a first line having a first end affixed to the boom, a second line interconnected to an opposite end of the first line and connected to the frame, and an actuator interconnected to the first and second lines. The actuator changes an angular relationship of the first and second lines so as to selectively tension the lines. The second line includes a first cable offset from linear alignment with the first line and a second cable extending in angular relationship with the first cable.
