Abstract

In a drilling device which has at least one free-fall winch and a control-line system with actuating and control elements by means of which the free-fall winch can be put into the state "free-fall operation", at least one safety-switch element (37; 47), apart from an actuating element (35 or 36), is provided in a control line (34, 31 or 33) for a control member (30 or 32). In this arrangement, a predeterminable position of the safety-switch element (37; 47) is a prerequisite for activation of the control member (30 or 32) for the state "free-fall operation". In particular, a safety-switch element (47) is allocated to an actuating system (42, 43, 44, 45, 46) for the rotary mechanism of the drilling device and/or to an actuating system for the travelling mechanism of the drilling device. <IMAGE>
