A carriage (4) that moves in a safety rail (1) and stops in the said rail when it takes a position deviating from its forward travel in the rail and its collision edge (10) hits the brackets (2) formed in the rail. Substantially at the end of the carriage (4) a bracket pair (9) has been formed by means of which the carriage takes support from the rail (1) front edge and the inner surfaces (11) of which are also adjusted to encounter the inward bent rims (3) of the rail, which tend to depart upon locking. |
