摘要
A self-locking descender 10 includes a pair of parallel flanges (side plates) 14, 16 having a fixed transverse spindle 22 on which is mounted rotationally a plate 20 equipped with three studs 24, 26, 28 for guiding the rope 12 through a half-turn. The intermediate stud 26 is coaxial with the spindle 22, and a braking roller 34 traverses an aperture 30 in the plate 20, reacting with the lower stud 28 in order to ensure wedging of the rope 12 in the event of release of a control handle 44. The curved aperture 30 is centered on the spindle 22 and the handle 44 is hinged to the plate 20. Application: climbing, mountaineering, speleology and building sites. IMAGE
