Abstract

L'invention concerne un contrepoids (2) et un ascenseur (10) doté d'au moins un contrepoids (2). Le contrepoids (2) est conçu sous forme de contrepoids sans cadre. Il comprend plusieurs segments de contrepoids (2.1, 2.2), les segments de contrepoids (2.1, 2.2) étant disposés dans l'état monté verticalement et en série les uns par rapport aux autres. Un premier segment de contrepoids supérieur (2.1) porte ici un second segment de contrepoids suivant (2.2). Sur le côté inférieur (3.1) du premier segment de contrepoids supérieur (2.1) est prévu un premier moyen de liaison (4.1) et sur le côté supérieur (3.2) du second segment de contrepoids suivant (2.2) est prévu un second moyen de liaison (4.2) pour que le second segment de contrepoids suivant (2.2) puisse être placé par un assemblage des premier et second moyens de liaison (4.1, 4.2) sur le premier segment de contrepoids supérieur (2.1).
