  • Patent number: 11118416
    Abstract: A device includes a first cavity sized to hold a first cassette of tubulars, a second cavity sized to hold a second cassette of tubulars, and a first lifting mechanism disposed in the first cavity. The first lifting mechanism when in operation lifts the first cassette of tubulars from a horizontal orientation to a vertical orientation with respect to a drill floor. The device also includes a second lifting mechanism disposed in the second cavity, wherein the second lifting mechanism when in operation lifts the second cassette of tubulars from the horizontal orientation to the vertical orientation and a drive mechanism that when in operation rotates the device by a predetermined amount to dispose the first cavity in a region directly proximate to the drill floor.
