ABSTRACT:
An arrangement for handling a drilling equipment comprising clamping jaws (11a, 11b) mounted rotatably with respect to the axis of a drill tube (8a, 8b) and a breaking device (7) mounted rotatably about the axis of the drill tube (8a, 8b) and movably in the longitudinal direction of a feed beam (3), which breaking device can be connected to the drill tube (8a, 8b) or the like unrotatably with respect thereto. To move the drill tube (8a, 8b) or the like to the drilling position and away from it, respectively, the breaking device (7) is mounted turnably about an axis transverse to the longitudinal axis of the feed beam (3), which makes it possible to push the horizontal tube (8b) or the like into the breaking device (7) turned to the direction transverse to the feed beam (3) and to fasten it to the breaking device, after which the tube (8b) can be turned into a drilling center between a rotating mechanism (5) and the previous drill tube (8a) by moving the breaking device (7) along the feed beam (3).
