ABSTRACT:
A monitoring apparatus for an elevator in which the cage floor positions are usually displayed roughly in analog form, and are displayed in digital form at the time of a disaster or at the time of selection, thereby to present a cage floor position display which is easy to see and which adapts to the different situations. The elevator monitoring apparatus comprises cage position display selection means for changing the manner in which the cage's floor position is being displayed from an analog cage position display form, which indicates the cage's floor position as a rough floor position within a building, to a digital cage position display form, whereby the exact floor position during a disaster condition such as a breakdown is displayed, in response to the activation of a selection switch.
