Abstract

L'invention concerne une bobine de support de câble d'ascenseur (1), telle qu'elle peut en particulier être utilisée pour actionner un poids de compensation de type câble pour rallonger un système d'ascenseur pouvant être rallongé et se présentant sous la forme d'un ascenseur d'escalade. La bobine de support de câble d'ascenseur (1) comprend une bobine de support (3) et un câble d'ascenseur (5) enroulé sur la bobine de support (3). La bobine de support (3) présente également un noyau de bobine (9) s'étendant dans une direction axiale (7). La bobine de support (3) présente par ailleurs respectivement aux extrémités du noyau de bobine (9) opposées dans la direction axiale (7) une plus petite délimitation latérale (11) s'étendant dans un plan transversal à la direction axiale. La bobine de support (3) présente en outre respectivement aux extrémités du noyau de bobine (9) opposées dans la direction axiale (7) et par exemple plus à l'extérieur dans la direction axiale (7) par rapport aux plus petites délimitations latérales (11) une plus grande délimitation latérale (13) s'étendant dans un plan transversal à la direction axiale (7). Les plus grandes délimitations latérales (13) présentent un diamètre (D2) plus grand que celui des plus petites délimitations latérales (11). Les plus grandes délimitations latérales (13) sont réalisées sur la bobine de support de câble d'ascenseur (1) sous la forme de composants pouvant être séparés. Pour rallonger l'ascenseur d'escalade, il est possible de remplacer une chaîne de compensation du poids (39) installée précédemment par le câble d'ascenseur (5) agissant en tant que câble de compensation du poids (31). Une première partie de la longueur du câble de compensation du poids (31) peut être déroulée de la bobine de support de câble d'ascenseur (1) et accrochée à la cabine d'ascenseur (23) et au contrepoids (25). La bobine de support de câble d'ascenseur (1) peut ensuite, une fois la plus grande délimitation latérale (13) enlevée, être fixée de manière peu encombrante au contrepoids (25) avec la partie du câble de compensation du poids (31) restant sur la bobine.
