Abstract

Un treuil pour ascenseur, adapté pour une installation dans différentes orientations. L'invention concerne un treuil (5) muni d'un moteur électrique (6), d'une poulie (8), et d'un frein (10) disposés en série. Le frein (10) est doté d'un tambour de frein (14) couplé au moteur électrique (6) ; de bras de frein (16a, 16b) supportés à rotation et équipés d'éléments de frein (15a, 15b) engageant le tambour de frein (14) ; de ressorts de frein (18a, 18b) pour presser les éléments de frein (15a, 15b) contre le tambour de frein (14) ; et d'éléments de libération de frein (20a, 20b) pour entraîner les bras de frein (16a, 16b). Un plan de projection sensiblement en forme de L est formé par le moteur électrique (6) et les bras de frein (16a, 16b). Les moyens de libération de frein (20a, 20b) sont disposés côte à côte le long de la direction de l'extension des bras de frein (16a, 16b). La hauteur du frein (10) est inferieure à celle du moteur électrique (6). La structure permet au moteur électrique (6) et au frein (10) d'être utilisés, pouvant pivoter de 180 degrés dans n'importe quelle direction autour de l'arbre de sortie (9) du moteur électrique (6).
