  • Patent number: 11235449
    Abstract: A setting tool includes: a body with at least a drive shaft connected to a pull rod designed to be screwed onto the crimp part, to drive the pull rod in rotation along an axis; a draw sleeve fixed to the body and connected to the pull rod, to translate the pull rod along the axis; and a placing nose, to house the pull rod rear end, the drive shaft front end, and the draw sleeve. The draw sleeve front end includes a cavity opening onto a first through hole on the side wall, and a second hole on the drive shaft axis of rotation, the through holes allow the pull rod front end to pass through the holes, to allow the pull rod rear end to pass through the first through hole, and to enable the pull rod to be placed along the drive shaft axis of rotation.

  • Patent number: 10591374
    Abstract: A Device for measuring a force applied by a fitting apparatus provided with a threaded rod having an external or internal thread, includes a hydraulic chamber containing a fluid; a piston configured to slide inside the hydraulic chamber; a threaded connector fixed to the piston, the threaded connector having a thread configured in such a way that the threaded rod screws onto the threaded connector, so that the threaded rod can impose an axial force on the piston resulting in travel of the piston in the hydraulic chamber; and a pressure gauge communicating with the hydraulic chamber, configured to measure a pressure inside the hydraulic chamber created by the axial force applied on the piston by the threaded rod.
