A cable transportation system comprising: at least a cable; an upstream station and a downstream station between which the cable extends; a plurality of supporting intermediate structures for supporting the cable between the upstream station and the downstream station; a plurality of transporting units coupled above the cable in a configuration suspended in the void and free to swing; an alarm device configured for detecting the contact between the transporting units and the supporting intermediate structures when a threshold tilting angle of the transporting units is exceeded and for emitting a relative alarm signal.

In order to enhance the safety of a cableway, in particular when a cable car passes through a cableway support of the cableway, according to the present teaching a detection device having at least one evaluation unit and at least two sensors connected to the evaluation unit is provided on at least one cableway support. A first sensor is located in the entry area of the cableway support in order to detect the presence of a cable car in a detection area of the first sensor. A second sensor is located in the exit area of the cableway support in order to detect the presence of a cable car in a detection area of the second sensor. The detection device is provided in order to detect a number of cable cars between the first sensor and the second sensor and to generate a fault signal when the detected number exceeds a predefined maximum number.

In order to be able to reliably prevent the departure of a vehicle without a locking of the closure device in a cableway with a locking monitor, a second receiving device is provided in the movement direction of the vehicle after the first receiving device. After the start of the vehicle in the first station, the transponder of the vehicle enters the effective range of the second receiving device, and the transponder transmits a signal with the locking state to the second receiving device. The cableway is stopped before the vehicle leaves the first station when the signal to the second receiving device indicates a faulty lock mechanism.
