Supporté sur les éléments supports en position sortie, le châssis de la plateforme de support peut être abaissé de manière à reposer sur le dessus des structures de paroi de la cage d'ascenseur, en vue du support vertical de la plateforme de support dans la cage d'ascenseur, et, lorsque lesdits éléments supports sont en position rentrée, la plateforme de support (3) peut être déplacée verticalement dans la cage d'ascenseur sans que les éléments supports ne constituent un obstacle. Parmi lesdits éléments de support figurent des éléments de support (8a, 8b) qui peuvent être déplacés dans des directions latérales opposées (D1 et D2) en position sortie. Dans ledit agencement d'ascenseur se trouve un palier d'étage (L) sur un côté du châssis de support (4). Le châssis (4) de la plateforme de support (3) comprend des moyens de commande (A) sur son côté palier d'étage (L), au moyen desquels les éléments supports (8a, 8b), qui peuvent être déplacés dans des directions latérales opposées (D1 et D2) en position sortie, peuvent être amenés en position sortie et/ou en position rentrée. Selon le procédé, les éléments supports (8a, 8b) sont amenés en position sortie et/ou en position rentrée d'un palier d'étage (L) sur un côté du châssis de support (4).
