Abstract
A vehicle that is guided by a guiding system is monitored for derailment. The guiding system has a guiding member interacting with a railhead of a rail that guides the vehicle. The device includes a clamp with a bottom jaw tightly surrounding the railhead in a contactless manner in the closed position thereof, capable of opening the jaw when interaction is lost between the guiding member and the rail. The opening results when the railhead at least partially exits the jaw. A top rod of the clamp enables mechanical transmission of the opening of the jaw to a switch. The switch has a nominal configuration corresponding to the closed position of the clamp during correct re-railing and an alarm configuration generated by mechanical transmission of the opening of the jaw to the switch. The alarm configuration actuates a safety system of the guided vehicle.
