• the cable car drive 5 can also be activated again from the central control room 17 after the closed position has been reached, or the speed can be increased again, for example by providing a central control desk (not shown) in the central control room 17, via which the control units 4 can be controlled.
• the is not approached respective cable car drive 5 but automatically when the closed position of the safety barrier 2 is detected by the respective sensor 3 and a corresponding sensor signal Y has been transmitted to the control unit 4.
• the cable cars S1-S3 can advantageously be centrally controlled and at least partially automated operation of the cable cars S1-S3 can be achieved, so that no operating personnel B has to be present directly on site in the cable car stations 1a, 1b in order to to close the safety barriers 2.
• the safety barriers 2 can in turn also be actuated by a mobile remote control unit 7b.
• the safety barriers 2 can be closed and, preferably, the respective cable car drive 5 can be restarted, e.g. locally independently of the cable car stations 1a, 1b and the central control room 17, as indicated in FIG.
• the communication between the mobile remote control unit 7b and the control unit 4 of the respective cable car S1-S3 is preferably wireless, for example via a suitable radio link.
• a suitable mobile phone in particular a smartphone and / or a portable computer, in particular a tablet computer, could for example be provided as the mobile remote control unit 7b.
• a camera 10 see FIG Videos are presented on a display unit, preferably in real-time transmission.
• the display unit can for example be provided within the central control room 17, e.g. integrated in a central control panel in the form of a monitor.
• a suitable mobile remote control unit 7b could, for example, also serve as the display unit.
• the situation in the area of the triggered safety barrier 2 can be checked via the display unit in the central control room 17 (or via the mobile remote control unit 7 b) being checked.
• the safety barrier 2 On the basis of the images or videos transmitted by the camera 10, it is easy to determine whether there is still a potential risk. If necessary, persons of operating personnel B and / or emergency services can go to the site if, for example, passengers were injured when the safety barrier 2 was triggered. If it is determined on the basis of the transmitted images or videos that there is no longer any risk potential, the safety barrier 2 can be operated by means of the respective stationary and / or mobile remote control unit 7a, 7b can be moved back into the closed position and the cable car drive 5 can preferably be restarted automatically.
• a mechanical contact switch, inductive sensor, capacitive sensor, light barrier, laser sensor, magnetic sensor, ultrasonic sensor, etc. is provided as sensor 3 for detecting the opening state of safety barrier 2
• a separate camera is provided for optical monitoring of safety barrier 2 10 required.
• the camera 10 of the camera system K can advantageously also be used to transmit the recorded images and / or videos to the display unit.
• one or more alarm units 8 can again be provided inside and / or outside of the cable car stations 1a, 1b in order to trigger an alarm when a safety barrier 2 has been actuated.
• alarm units 8 could be provided within the cable car stations 1a, 1b in order to signal the triggering of the safety barrier 2 to the passengers.
• an alarm unit 8 is also provided in the central operating unit 17 in order to signal the operating personnel B by means of an alarm signal when a safety barrier 2 has been triggered and preferably also which safety barrier 2 has been triggered.
