Summary: | Control equipment for guiding a drill rod. The control equipment including a frame and two guide jaws provided with guide surfaces and mounted movably in relation to the frame. The drill rod is set between the guide jaws during drilling. Actuators move the guide jaws in relation to the drill rod. Synchronization means are coupled between the guide jaws, such that the guide jaws always move in opposite directions to one another and at the same speed. A detector detects that the guide surfaces of the guide jaws are in contact with the drill rod. |
