FIELD: machine building.SUBSTANCE: described is a belay, of static or dynamic type, and a descender, of self-blocking type or not, for securing one or more ropes (10) comprising main body (1) composed of at least two or more flat plates (2, 2A, 3) constrained one to another according to planes preferably parallel, or slightly tilted, by a plurality of spacer pins (4 - 7). Rope(s) is/are inserted inside body of device which further comprises a first karabiner (15) hooked to main body by passing through an opening (8) in device body. Karabiner (15) is movable in opening between an unlocking position of the rope, that is usual use condition, and an emergency position wherein rope is blocked, and vice versa.EFFECT: device further comprises a hole (60) passing through device body allowing hooking of first karabiner (15) removed from opening (8) or of a second karabiner (61) around which rope(s) (10) is/are passed, and further means for constraining device body to a fixed hooking point (80), which comprise at least one through hole (70) inside which a further respective karabiner (71) is hooked.12 cl, 4 dwg |
