Abstract
A method for gripping a tubular with a tubular gripping mechanism includes the steps of moving the tubular gripping mechanism adjacent the tubular, positioning a jaw assembly of the tubular gripping mechanism around the tubular, applying a force by an actuator onto the jaw assembly of the tubular gripping mechanism such that the jaw assembly moves so as to clamp onto the tubular, removing the force from the actuator onto the jaw assembly such that the jaw assembly remains clamped onto the tubular. The clamping force is directed to surfaces of the tubular gripping mechanism away from the actuator.
