Method of operating a cableway system, and cableway system

Abstract

A cableway system has a valley station and a mountain station. A supporting and conveying cable displace transport devices between the stations, and/or the system has at least one supporting cable, on which the transport devices are displaced with a conveying cable. The inclined positions of transport devices in relation to the vertical operating position are sensed by a respective sensor on the transport devices. When a first limit value for the inclined position of one of the transport devices is exceeded, a transmitter transmits a first control signal from the transport device to a receiver in one or both stations. The first control signal reduces the speed of the conveying cable. When a predetermined second limit value for the inclined position of a transport device is exceeded, a second control signal is transmitted to the receiver. The second control signal switches off the drive for the conveying cable.

1 . A method of operating a cableway system with terminal stations, a supporting and conveying cable by way of which transport devices are moved between the stations, and/or at least one supporting cable, on which the transport devices are displaced between the stations, the method which comprises:
 sensing inclined positions of respective transport devices in relation to a vertical operating position with respective sensors carried on the transport devices;   if at least one first limit value for an inclined position of one of the transport devices is exceeded, transmitting with a transmitter carried on the one transport device a first control signal to at least one receiver located in at least one of the stations, the first control signal causing a speed of the conveying cable to be reduced; and   if a predetermined second limit value for the inclined position of one of the transport devices is exceeded, transmitting with the transmitter a second control signal to the receiver, the second control signal causing a drive for the conveying cable to be switched off.   
   
   
       2 . The method according to  claim 1 , which comprises sensing, with the sensor located on the transport devices, deflections of the transport devices relative to the vertical in a direction of travel and deflections of the transport devices transversely to the direction of travel, and transmitting the measured values to the at least one receiver located in the cableway system by way of the transmitter carried on the transport devices. 
   
   
       3 . The method according to  claim 1 , which comprises transmitting all the measured values emitted by the sensor to the at least one receiver. 
   
   
       4 . The method according to  claim 1 , which comprises transmitting to the at least one receiver substantially only those measured values emitted by the sensor which indicate deflections of the transport devices beyond one of the predetermined limit values. 
   
   
       5 . The method according to  claim 1 , which comprises, if one of the transport devices is deflected by more than approximately 10°, reducing the speed of the conveying cable, and, if one of the transport devices is deflected over approximately 20°, bringing an operation of the cableway system to a standstill. 
   
   
       6 . A cableway system, comprising:
 terminal stations including a valley station and a mountain station;   at least one supporting and conveying cable for moving transport devices between said stations, and/or at least one supporting cable on which said transport devices are displaced between said stations by way of at least one conveying cable;   at least one receiver mounted to at least one of said terminal stations;   sensors mounted to at least some of said transport devices and configured to sense an inclination of respective said transport devices relative to a vertical operating position;   transmitters mounted to said at least some transport devices and configured to receive from said sensors measured values and to transmit the measured values emitted by said sensor to said at least one receiver, and causing an operation of the cableway system to be controlled in dependence on the measured values.   
   
   
       7 . The cableway system according to  claim 6 , wherein said sensors disposed on said transport devices are configured to sense and indicate a deflections of the respective said transport devices relative to the vertical both in a direction of travel and transversely to the direction of travel. 
   
   
       8 . The cableway system according to  claim 6 , which comprises an electric battery and/or a photovoltaic element mounted to said transport devices. 
   
   
       9 . The cableway system according to  claim 6 , which comprises relay stations disposed on supports of the cableway system. 
   
   
       10 . The cableway system according to  claim 9 , wherein said relay stations and said at least one receiver are connected to one another via signal lines and/or by radio. 
   
   
       11 . The cableway system according to  claim 6 , wherein said receivers are connected to one another via signal lines.
