There is disclosed herein a descent device (10) comprising a hollow spool (12) rotatable about a rotational axis (14) and a lifeline, in the form of a braided steel cable (not shown), wound about the spool (12). A centrifugal brake mechanism (18) including a brake assembly, comprising a pair of brake shoes (20) and associated brake pads (21), is engageable with the spool (12) to apply a braking force to the spool (12) as the spool (12) rotates. Biasing members, in the form of a compression springs (22), extend between the brake shoes (20) for biasing the brake shoes (20) and pads (21) into engagement with the spool (12).
La présente invention concerne un dispositif descendeur (10) comprenant une bobine creuse (12) rotative autour d'un axe de rotation (14) et une corde d'assurance, sous la forme d'un câble tressé en acier (non montré), enroulé autour de la bobine (12). Un mécanisme de freinage centrifuge (18) comprenant un ensemble de freinage, comportant une paire de segments de freins (20) et des plaquettes de frein associées (21), peut être embrayé avec la bobine (12) afin d'appliquer une force de freinage sur la bobine (12) lorsque la bobine (12) tourne. Des éléments pousseurs, sous la forme d'un ressort de compression (22), s'étendent entre les segments de frein (20) afin de pousser les segments de frein (20) et les plaquettes de frein (21) et de les embrayer avec la bobine (12).
