A lifting machine image monitoring system in an elevator, escalator, or moving walkway, used for monitoring, at low cost and with ease, image data of to-be-monitored points at the same time points. The lifting machine image monitoring system has monitor cameras (2a-2f) for outputting image data (8a-8f) of to-be-monitored points, an image data storage device (6a) for storing in time series the image data (8a-8f), and stored-image-data display devices (6, 6c) for displaying image data in response to monitoring demands (11, 12) from a user. The image data storage device (6a) outputs monitoring image data (9a-9c), corresponding to the monitoring demands (11, 12), to the stored-image-data display device (6c). In response to a to-be-monitored point (11) and one piece of information (12) on the date/time at which reproduction starts, the stored-image-data display devices (6, 6c) display image data (10a-10c), while synchronizing each data, of the to-be-monitored points at the reproduction starting date/time.
