Abstract:
A gripping apparatus for engaging a tubular. In one embodiment, the gripping apparatus comprises a collet structure adapted to receive the end of a tubular therein. A barrel is moveably engaged with the collet structure and is moveable from an open position to a made-up position. The collet structure comprises a substantially cylindrical top section and a bottom section that is divided into a plurality of elongate blades each having a gripping structure formed at an unsupported end thereof. In the made-up position, a flared bottom section of the barrel engages and compresses the respective gripping structures, flexing the blades inwardly and causing engagement of the gripping structures with the sidewall of the tubular. In one embodiment, the barrel is slidably engaged with the collet. In an alternative embodiment, the barrel takes the form of a nut that is threadably engaged with the collet.
