Abstract
The auxiliary device is needed when the elevator stands in the elevator shaft outside a station. The auxiliary device includes an auxiliary drive device for the payload receptacle. For sight-free observation of the auxiliary device there is arranged an image transmission device, which includes a sensor, a display device and a transfer path. The sensor serves for detection of images which illustrate a drive pulley coupled with the auxiliary drive device. The display device serves for visualization of the images detected by the sensor, and the transfer path serves for transmission of the images detected by the sensor to the display device.
