When the tool is suspended from the top drive, its components are rotationally locked to facilitate insertion into the casing stand on top of a string being run in the hole. Some set down weight allows top drive rotation to move a multi-ramped mandrel axially because that mandrel is rotationally locked to the housing that is held fast by the spring loaded dogs bearing on the casing. Once the slips are extended with a specified torque applied from the top drive, further setting down weight locks the components and the housing so that applied rotation with setting down weight will turn the casing string but will not torque up the slips beyond their set position. | 04-23-2015 |
