Abstract
A single joint elevator for releasably securing a tubular segment for hoisting the tubular segment into position to be threadably coupled to a pipe string suspended in a borehole. The elevator comprises two pivotally coupled jaw retainers securing jaws for engaging and gripping the tubular segment. A powered door is pivotally coupled to a first jaw retainer for selectively securing the second jaw retainer. The powered door includes a pivotable collar, a linear actuator assembly, and a linkage mechanism for selectively closing the door and clamping the distal end of the second jaw retainer to the distal end of the first jaw retainer. The actuator assembly clamps the jaw retainers with sufficient force for the jaws to grip and support the tubular segment for lifting.
