摘要
<p>The device has a rope-ladder (3) twistable around its longitudinal axis and stretching between two linkage points. The twisting performance of the ladder is controllable by stop or brake medium. The pivoting range of a ladder step of the ladder is bound by an adjustable stopper (8). The stopper acts on the ladder step of the ladder in a climbing direction. The brake medium is twistable around the longitudinal axis of the ladder.</p>
