Abstract: Apparatus for gripping a tubular member where the apparatus includes a die and a die holder, and where at least one of the die or the die holder, on its portion facing the other, has at least two axially formed ridges that complementary fit in valleys in the other of the die or the die holder. The ridges have a larger bottom width than top width. The centre lines of the die ridges are substantially parallel at a distance, and the die, when unengaged, is radially movable between abutment of the die ridges to the die holder and abutment of the die to at least one stop member of the die holder.

Abstract: An auxiliary arm for drilling equipment (1) including a top drive drilling machine (4) which is vertically movable along a drilling centre (10), and in which at least one pipe manipulator (6) is arranged to move pipes (8) between the drilling centre (10) and a pipe magazine (7), and in which, beside the drilling centre (10), at least one at least remote-controllable or automatically operated auxiliary arm (12, 14) for the pipe (8) is arranged, the gripping member (24) of the auxiliary arm (12, 14) being positional at least at the drilling centre (10) or in the working area of the pipe manipulator (6).
