Abstract
Each of the operating stations is provided with a signal directing means for emitting a call signal indicating a need for servicing, a positional reference marker in order to initiate a braking operation and a locating reference marker for exactly locating a service tender relative to the operating station. The service tender carries a signal receiving means for receiving a call signal emitted for an operating station during passage by the operating station. In addition, the service tender includes a sensor which is responsive to the positional reference marker of the operating station to be serviced which serves to initiate braking of the motor for the service tender. Further, the service tender carries a locating device which cooperates with the locating reference marker of the operating station in order to locate the tender relative to the operating station for servicing purposes.
