The invention concerns a method which consists in providing installation of safety equipment on the cable which takes over from original anchoring elements of said cable, in case the latter breaks. Said safety equipment consists of a component (11) serving as hammer in the form of two half-shells, fixed on the cable (7), and a damping device (12) subject of the patent application FR-02 05105, in the form of a U-shaped or .OMEGA.-shaped gutter, which encloses the cable (7) and whereof the deformability corresponds to the variation in the length of the cable when its tension is released after breaking.
Le procédé consiste à prévoir l~installation d~équipements de sécurité sur le câble qui prennent le relais des ancrages primitifs de ce câble, en cas de rupture de ce dernier. Ces équipements de sécurité sont constitués d~une pièce (11) faisant office de marteau en forme de deux demi-coquilles, fixée sur le câble (7), et d~un dispositif absorbeur (12) objet de la demande de brevet FR- 02 05105, en forme de goutière à section en U ou en .OMEGA., qui enveloppe ledit câble (7) et don~t la capacité de déformation correspond à la variation de longueur du câble lors de sa détente après rupture.
