<p>A pipe handling apparatus (35) is disclosed, which is adapted for automated drilling operations. Drill pipes (10) are manipulated between substantially horizontal and vertical positions, and the apparatus is used with a top mounted drilling device (22) which is rotatable about a substantially horizontal axis (1). The apparatus comprises a strongback (4) provided with means (6,7,8) to hold and manipulate pipes. The strongback (4) is at one end portion rotatably connected to the same axis (1) as the drilling device (22). The strongback (4) moves up or down with the drilling device (22). A brace unit (5) is attached to the strongback (4) to be rotatable about a second axis (2) spaced apart from said first axis (1). The brace unit (5) has one end portion rotatable about a third axis (3).</p> |
