Abstract:
A tubular joint elevator includes a ringed portion configured to lift a tubular joint. The elevator includes an elevating mechanism disposed adjacent to the ringed portion, and configured to elevate the tubular joint. In some embodiments, the elevator includes first, second, and third doors. The elevator includes a first locking member, and the first door includes a first locking recess. The first locking member is axially displaceable between an advanced position and a retracted position such that it is either received in or separated from the first locking recess. The third door includes a locking pin, and the first door comprises a locking hole. The third door is longitudinally displaceable between a first position and a second position such that the locking pin is either separated from, or received in, the locking hole. Methods of using the same are also included.
