Abstract

Dispositif de freinage pour plate-forme élevée comprenant une plate-forme mobile le long dun mât généralement vertical soutenant un support vertical, qui comprend un ensemble dentrée en prise avec le support, un mécanisme dactivation centrifuge en communication avec lensemble dentrée et un frein à ressort qui réagit au mécanisme dactivation centrifuge. Le frein à ressort entraîne le support et arrête la plate-forme lorsque la plate-forme fait descendre le mât à un débit supérieur à une limite seuil supérieure.
