Abstract

Dans un ascenseur à double cabine pourvu d'une chambre de cabine supérieure et d'une chambre de cabine inférieure à l'intérieur d'un cadre de cabine, lorsque la charge à l'intérieur d'une cabine était inférieure à une valeur prédéterminée, il y avait un problème en ce que, alors qu'un long temps d'attente des passagers en attente pouvait être évité dans une opération d'appui pendant laquelle la cabine était déplacée vers l'étage où des passagers en attente étaient présents pour permettre l'embarquement, le temps nécessaire pour atteindre un étage cible était augmenté en raison du déplacement des cabines et de l'embarquement des passagers en attente.　Selon la présente invention, lorsque la charge à l'intérieur de la cabine atteint une valeur prédéterminée, il est possible de permettre à d'autres personnes d'embarquer dans la même cabine lorsque la charge dans la cabine et la charge dans l'autre cabine sont additionnées et que la charge additionnée est inférieure ou égale à une valeur nominale.　De ce fait, l'efficacité de fonctionnement d'un ascenseur à double cabine est améliorée par l'amélioration de la situation des passagers en attente au niveau des paliers et par la réduction de l'allongement du temps nécessaire pour atteindre l'étage cible.
