The handling system includes a housing for supporting the swivel bearing, a handling ring, a stem for supporting the load of the drill string during tripping, an elevator, elevator links for supporting the elevator from the handling ring, a traveling block, and support links for supporting the housing from the traveling block. The structural relationship between the handling ring, the stem, and the housing provides an alternative load path for elevator loads during tripping or when running well casing liner that bypasses the swivel bearing.
