Abstract
A detection system for a vehicle pulled by cable circulating between two stations. The system includes a beacon placed on the vehicle and a receiving antenna placed in each of the stations, and the vehicle includes at least one retractable element on the top of the vehicle and wherein the beacon emits only when the retractable element remains protruding from the vehicle. When the beacon emits, the receiving antenna situated in the station is informed of a risk of collision of an element of the vehicle with the station, thus being able to communicate the information to the control/command system of the cable. When the beacon is not emitting, the receiving antenna is idle and the vehicle can enter into the station.
