| 摘要 |
The invention relates to a drag chain (12) having additional protection against line breaks. The drag chain comprises links (20) or segments for guiding one or more lines, such as cables, hoses, or the like, wherein the links or segments can be pivoted in relation to each other in order to form a deflecting curve (28). The protective equipment comprises a detector, which is provided for monitoring the drag chain. The detector (16) is mechanically operatively connected to a low-elongation triggering string (30) and has a sensor (36) for sensing a kinematic parameter of the triggering string (30). A break (13) in the drag chain (12) can be detected in good time by means of the change of the kinematic parameter. Thus, guided cables, hoses, or the like can be protected against line breaks. |
