Abstract:
A tubular member handling apparatus including a tubular member running tool, an elevator, first actuators each extending between the running tool and the elevator, and second actuators each extending between the running tool and a corresponding first actuator. The running tool includes a slotted member having a plurality of elongated slots, a recessed member slidably coupled to the slotted member and having a plurality of recesses, and a plurality of rolling members each retained between one of the recesses and one of the slots. Each rolling member partially extends through an adjacent slot when located in a shallow end of a corresponding recess, and retracts to within an outer perimeter of the slotted member when located in a deep end of the corresponding recess.
