发明名称 Tubular handling device and methods
摘要 A tubular member handling apparatus (100) including a tubular member running tool (110), an elevator (120), first actuators (150) each extending between the running tool and the elevator, and second actuators (160) each extending between the running tool and a corresponding first actuator (150). The running tool includes a slotted member having a plurality of elongated slots, a recessed member (210) slidably coupled to the slotted member (220) and having a plurality of recesses, and a plurality of rolling members (230) each retained between one of the recesses and one of the slots. Each rolling member (230) partially extends through an adjacent slot when located in a shallow end of a corresponding recess, and retracts to within an outer perimeter (105) of the slotted member when located in a deep end of the corresponding recess.
