A lift cage door (4), comprising a crosspiece 8 which houses the drive mechanisms, an access aperture 12 and two cage doors or panels 14, 16 which are operatively connected to first motor means (24) which move the cage doors (14, 16) form an open position to a closed position. Advantageously, the cage (4) comprises second motor means (36) mechanically and operatively separate from the first motor means (24), wherein said second motor means (36) are connected to a blocking/releasing carriage (40) of the cage doors (14, 16). The blocking/releasing carriage (40) is connected to at least one chute connected to at least one of said cage doors (14, 16), so as to permit the blocking/releasing of the chutes independently of the actuation of the first motor means (24) and of the cage doors (14, 16). |
