A four-cornered, open frame, connected either to a top drive or to a traveling block, has an elevator at its lower end used to support the weight of the tubular string, and has a mud tool, a stabber, a guide, a spinner, a tong, a stabbing guide and a backup tong carried by the frame. A manipulator arm picks up a horizontal tubular, manipulates the tubular to vertical, and moves the tubular into the interior of the frame, allowing the tubular to be made up in the string while the string is being lowered into the wellbore.

Selon cette invention, un châssis ouvert à quatre angles, connecté soit à un dispositif d'entraînement par le haut soit à une moufle mobile, possède un élévateur au niveau de son extrémité inférieure utilisé pour supporter le poids de la colonne de tubage et possède un outil pour boues, un dispositif de pose de tuyau, un guide, un treuil, des clés, un dispositif de guide de vissage et des clés de blocage soutenues par le châssis. Un bras manipulateur saisit une pièce tubulaire horizontale, la manipule de façon à la mettre en position verticale, et la déplace à l'intérieur du châssis, permettant que cette pièce tubulaire constitue la colonne de tubage alors que celle-ci est abaissée dans le puits.
