    摘要: A method and apparatus for handling tubulars is provided. In one aspect, the present invention provides a spinner having a first arm having a first roller and a second arm having a second roller, the first arm and the second arm simultaneously adjustable to retain the tubular. The apparatus also includes a third roller capable of urging the tubular against the first and second rollers, wherein at least one of the first, second, and third rollers is actuatable to rotate the tubular. In one embodiment, the spinner further comprises a fluid operated cylinder for adjusting the first arm and the second arm. The arms are adjusted by actuating the cylinder extend or retract the first arm and the second arm.
