Abstract

Ascensor que comprende: una cabina (1) para subirse/bajarse dentro de un hueco de ascensor; una porción de control de funcionamiento (8) para controlar el funcionamiento de la cabina (1); una porción de vigilancia de sobrevelocidad (21) para detectar una posición de la cabina y una velocidad de la cabina, comparar una sobrevelocidad ajustada de acuerdo con la posición de la cabina con la velocidad de la cabina, y generar una señal de orden de frenado para detener la cabina (1) cuando la velocidad de la cabina alcanza la sobrevelocidad; y una porción de freno (7) para frenar la cabina (1) de acuerdo con la señal de orden de frenado procedente de la porción de vigilancia de sobrevelocidad (21), en donde la porción de vigilancia de sobrevelocidad (21) ajusta la sobrevelocidad independientemente de la porción de control de funcionamiento (8), caracterizado por que la porción de vigilancia de sobrevelocidad (21) ajusta la sobrevelocidad de manera diferente dependiendo de una dirección de marcha de la cabina (1) cuando la cabina (1) está localizada en la proximidad de una planta terminal.Elevator comprising: a car (1) for getting on / off inside an elevator shaft; an operation control portion (8) for controlling the operation of the booth (1); an overspeed monitoring portion (21) for detecting a car position and a car speed, comparing a set overspeed according to the car position with the car speed, and generating a braking command signal to stop the car (1) when the speed of the car reaches overspeed; and a brake portion (7) for braking the car (1) in accordance with the braking command signal from the overspeed monitoring portion (21), wherein the overspeed monitoring portion (21) adjusts the overspeed independently of the operation control portion (8), characterized in that the overspeed monitoring portion (21) adjusts the overspeed differently depending on a driving direction of the car (1) when the car (1) is located in the vicinity of a terminal plant.
