Abstract: The anti-extraction safety system incorporates, on each side, one side component which does not rotate with the corresponding roller, that incorporates at least one inclined flap articulated to pivot between a lowered position wherein its lower part extends under the rail head, and a raised position in which its lower part is laterally distanced from the rail. The pivot axis of the flap is inclined upwards and is located in the rear part of the flap, above the lower part in the lowered position. This flap is subjected to a downward return force which maintains it in the lowered position, but which allows it to pivot to the raised position when an upward force greater than the return force, is applied on its lower part.
