Abstract

Un corps de défense (41) est fixé à une paroi de quai et est monté, de façon à être engagé de manière amovible dans la direction verticale, dans une paire de guides (21a – 21d) qui se font face. Les guides (21a – 21d) s'étendent dans la direction verticale, et un élément d'arrêt (31) qui empêche le corps de défense (41) de se déplacer vers le bas est monté sur le bord inférieur de celui-ci. Pour le remplacement de la défense, lors de la première étape, le corps de défense (41) est suspendu par une grue ou un engin similaire, non représenté, et est extrait et retiré verticalement vers le haut des guides (21a – 21d). Lors de la deuxième étape, un nouveau corps de défense est suspendu de la même manière, inséré vers le bas dans la direction verticale depuis le dessus des guides (21a – 21d), et monté de manière à être en prise avec les guides (21a – 21d). Le nouveau corps de défense est empêché de se déplacer vers le bas par son bord inférieur venant en butée contre le bord supérieur de l'élément d'arrêt (31).
