Abstract

L'invention concerne un frein de treuil d'ascenseur dans lequel un sabot de frein est supporté par un noyau mobile. Le déplacement du noyau mobile permet au sabot de frein d'être déplacé entre une position de freinage dans laquelle le sabot de frein est en contact avec une surface de freinage et une position libérée dans laquelle le sabot de frein est séparé de la surface de freinage. Un élément élastique est disposé entre le noyau mobile et le sabot de frein. La quantité de compression de l'élément élastique lorsque le sabot de frein est situé au niveau de la position libérée est supérieure à la quantité de compression de l'élément élastique lorsque le sabot de frein est situé au niveau la position de freinage.
