Abstract

L’invention concerne un palan pour ascenseur, dans lequel un boîtier latéral de frein est fixé, mutuellement opposés, à un boîtier latéral du moteur, dans lequel est installé un moteur. Une poulie est montée en rotation sur un arbre fixe à travers le boîtier latéral de frein et le boîtier latéral du moteur. Les extrémités d’une paire de bras de freins sont fixées en rotation au boîtier latéral de frein, et des mâchoires de freins en contact coulissant avec la surface de freinage d’un tambour de frein sont montées sur les bras de freins. Un ressort de freinage séparant la paire de bras de freins est installé dans le boîtier latéral de frein entre la paire de bras de freins. Un électroaimant faisant tourner les bras de freins en attirant les autres extrémités de la paire de bras de freins contre la force élastique du ressort de freinage est installé dans le boîtier latéral de frein entre les autres extrémités de la paire de bras de freins.
