    摘要： An oilfield elevator is disclosed and has first and second body halves pivotally-coupled at a hinge and moveable between an open position and a closed position to receive and move a tubular segment. Slips are slidably received within corresponding tapered slots in the elevator and are configured to translate vertically within the tapered slots and, at the same time, radially so as to be able to capture a wider range of tubular having varied outside diameters. Tension handles are pivotally-coupled to the first and second body halves and moveable between locked and unlocked positions. Locking the tension handles engages the slips via biasing members, and forces the slips into radial contact with the tubular segment. Unlocking the tension handles releases the biasing members.
