CA 2302231

An apparatus is provided with position sensors. When the apparatus has moved one tubular into alignment with another tubular a button on a remote control console is pressed to memorise the position. After the next tubular has been gripped by the apparatus a "recall" button is pressed and the apparatus automatically moves the next tubular to the memorised position. This saves vital seconds in joining tubulars and also reduces the likelihood of threads being damaged due to misalignment of the tubulars.

L'invention concerne un appareil (101) doté de détecteurs de position. Lorsque l'appareil (101) déplace un tube dans l'alignement d'un autre tube, on presse un bouton se trouvant sur une console de commande à distance pour mémoriser la position. Après saisie du tube suivant par l'appareil, on presse un bouton "rappel" et l'appareil (101) déplace automatiquement le tube suivant à la position mémorisée. Cela permet de gagner des secondes précieuses dans le raccordement de tubes et également de réduire l'éventualité d'un endommagement de fils suite à un défaut d'alignement des tubes.
