Inland navigation vessels - Outboard ladders
This document is applicable to outboard ladders for inland navigation vessels. Outboard ladders are used on inland navigation vessels having great side heights to facilitate safe climbing into ship's boats, safe disembarking or safe crossing over onto vessels in the case of significantly different boarding heights.
This document specifies safety requirements on design, dimensions and strength and test conditions for outboard ladders.
Outboard ladders are intended for that range where boarding stairs according to EN 1502 are not sufficient in length. This range starts at a boarding height of approximately at 2,8 m above the light water-line.
Outboard ladders are not intended for use by passengers.
Fahrzeuge der Binnenschifffahrt - Außenbordleitern
Dieses Dokument ist anwendbar für Außenbordleitern für Fahrzeuge der Binnenschifffahrt. Außenbordleitern werden auf Fahrzeugen der Binnenschifffahrt mit großer Seitenhöhe eingesetzt, um den sicheren Einstieg in Beiboote, den sicheren Übergang zum Land oder das sichere Übersteigen zu benachbarten Schiffen bei sehr unterschiedlichen Bordhöhen zu ermöglichen.
Dieses Dokument legt Sicherheitsanforderungen an Bauart, Maße und Festigkeit sowie Prüfbedingungen für Außenbordleitern fest.
Außenbordleitern sind für den Bereich vorgesehen, in dem Außenbordtreppen nach EN 1502 bezüglich ihrer Länge nicht ausreichen. Dieser Bereich beginnt bei einer Bordhöhe von ungefähr 2,8 m über der Leerwasserlinie.
Außenbordleitern sind nicht für die Benutzung durch Fahrgäste vorgesehen.
Bateaux de navigation intérieure - Échelles de bordé
Le présent document est applicable aux échelles de bordé pour les bateaux de navigation intérieure. Les échelles de bordé sont utilisées sur les bateaux de navigation intérieure avec de grandes hauteurs de muraille pour assurer la sécurité des transferts vers les canots, du débarquement sur la terre ferme ou du passage sur des navires à pont inférieur lorsque les hauteurs pour l’embarquement sont significativement différentes.
Le présent document spécifie les exigences de sécurité relatives à la conception, aux dimensions, à la résistance et aux conditions d’essai pour les échelles de bordé.
Les échelles de bordé sont conçues pour la gamme de bateaux de navigation intérieure pour lesquels les escaliers de bordaille conformes à l’EN 1502 ne sont pas suffisamment longs. Cette gamme démarre à une hauteur de bord de plus d’environ 2,8 m au-dessus de la ligne d’eau à vide.
Les échelles de bordé ne sont pas destinées à être utilisées par les passagers.
Plovila za celinske vode - Zunanje lestve
Ta dokument se uporablja za zunanje lestve za plovila za celinsko plovbo. Zunanje lestve se uporabljajo na plovilih za celinsko plovbo z veliko bočno višino, da se omogoči varen vstop na plovilo, izkrcanje ali varno prestopanje na plovila v primeru zelo različnih višin vkrcanja.
Ta dokument določa varnostne zahteve glede zasnove, dimenzij in trdnosti ter preskusne pogoje za zunanje lestve.
Zunanje lestve so namenjene tistim razponom, kjer stopnice za vkrcanje v skladu s standardom EN 1502 niso dovolj dolge. Ta razpon se začne pri višini vkrcanja približno 2,8 m nad vodno gladino pri lahki teži plovila.
Zunanje lestve niso namenjene potnikom.
