An aerial cable transportation system comprising: at least one hauling cable; a first fixed structure; at least one transportation unit; a plurality of sensors configured for detecting the passage of the transportation units; a control unit; wherein the plurality of sensors comprises at least a first sensor arranged at the exit area of the first fixed structure and at least a second sensor downstream of the first sensor, respectively, at is least a distance s1 from the first sensor measured in cable-meters; wherein the control unit is connected to the sensors and is configured for: upon the passage of each transportation unit at the first sensor, starting to count the meters of cable fed outside the first fixed structure; when the counting of the meters of cable fed outside the first fixed structure reaches amounts about equal to the at least one distance s1, autonomously activating safety procedures if the passage of the transportation unit is not detected by each corresponding second sensor downstream of the first sensor.

Parking system to improve the parking and feeding of cableway vehicles. Each cableway vehicle has connecting elements designed to detachably connect adjacent cableway vehicles. When parking, a jointly movable vehicle combination of detachably connected cableway vehicles is parked on the parking track. For feeding cableway vehicles, a parking track conveyor pulls the vehicle combination from the parking track toward the feed track until the detachably connected connecting elements of two cableway vehicles at an end of the vehicle combination facing the track end are in an effective range of an actuating device. The actuating device detaches the connecting elements between these two cableway vehicles, and the feed track conveyor moves the cableway vehicle located at the end of the vehicle combination facing the track end away from the parking track.
