Abstract
A rotary table has a non-circular drive recess in the central opening which carries a fitting adapter ring to which slip carriers are attached. A plurality of slip carriers are distributed about the periphery of the adapter ring and extend down into the central opening of the rotary table. A slip and die arrangement is situated on each slip carrier. Slip manipulation drive cylinders, as an option, are distributed about the adapter ring periphery and move a synchronizer ring that moves the slips vertically to grip or release pipe extending through the opening of the rotary table. The drive cylinders, as an option, may be comprised of flexible bellows.
