Abstract

A self-locking descender enabling its user to make a controlled descent down an anchored rope has the rope 12 wound in an S-shape around a movable pulley 16 and a fixed pulley 14, the movable pulley 16 comprising protuberances 50, 52, one of which co-operates with a locking element 54 to form a rope brake operative when a control lever 42 rigidly secured to the pulley 16 is in a top or bottom end position. The user's weight, acting via the snap hook 36 of his harness, effects clockwise rotation of the control lever 42 and urges it into its top end position as shown. When the control lever 42 is moved into an intermediate position (Figure 4, not shown), the rope 12 runs freely over the pulleys 14, 16 allowing descent of the user. The descender is of use in connection with potholing, mountain climbing, and construction sites.
