US Patent 10934800 Rotating hanger running tool

A running tool runs a hanger and tubing string into a wellbore. A tool body threads onto the hanger. Lugs are held on the body with catches. During the threading, triggers engage with the hanger and release the catches, and springs bias the lugs to an extended condition. Being extended, the lugs can engage in slots in the hanger, such as flutes in the hanger's flange. The engagement of the lugs with the slots prevents further threading of the tool on the hanger while the threads keep the tool connected to the hanger. The tubing string can be rotated and moved axially during cementing to distribute the cement evenly. Once done, the lugs can ratchet out of the slots as the tool is unthreaded from the hanger.
