| 摘要 |
The invention relates to a cable brake (15) in which, the instant an electromagnet (36) is switched off, a mass (37) falls down guide rods (38) under the effect of gravity and collides with a first arm (30) of a first trigger lever (28). As a result of the rotation of the first trigger lever (28), a pawl (32) releases a crossbar (27), whereupon pressure springs (22) press a released braking plate (18) against a cable strand (3) and bring the cable strand (3) to a halt. A second pressure plate (23) may be displaced along the path shown with a w, by means of a screw (24), arranged on a housing (16) and a nut (25), arranged on said second pressure plate (23), whereby the pressure springs (22) are pre-tensioned according to the position of the second pressure plate (23). The pressure springs (22) are released in the end position shown with a el, whereby a first pressure plate (21) and a release bar (26), engaging with the first pressure plate (21), may be moved into the starting position thereof. |
