BS EN 17361 pdf free download.Inland navigation vessels – Outboard ladders.
1 Scope This document applies 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. Boarding ladders are not intended for use by passengers. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

The dimensions are shown in Figures 1 to 5 and in Table 1. Edges shall be rounded to min. R 1,5 mm. Data which have not been specified shall be selected as appropriate. 4.2 Parts 4.2.1 General Ouboard ladders are not expected to conform to the designs illustrated here; however the dimensions and specifications given shall be followed. Maximum permissible masses are shown in Table 1. 4.2.2 Stringer and handhold 4.2.2.1 The stringers extending on both sides above the platform are used as handholds. On that side which faces the vessel’s wall, the handholds shall be designed according to Figure 5. 4.2.2.2 Stringers and handholds shall be made from tubular section tube with ∅ 40 mm. Alternative profiles with the same strength are acceptable. 4.2.3 Steps 4.2.3.1 General Steps are the rungs and the platform. 4.2.3.2 Rung Rungs shall be made of rectangular hollow profile, e.g. 40 mm × 30 mm.BS EN 17361 pdf download.
