15、 12EN 13574:2001 (E) 3 Foreword This European Standard has been prepared by CEN /TC 15, Inland navigation vessels, the Secretariat of which is held by DIN. This European Standard shall be given the status of a national standard either by publication of an identical text or by endorsement, at the lat
16、est by January 2002, and conflicting national standards have to be withdrawn at the latest by January 2002. This standard specifies requirements for permanently installed climbing devices with a length not exceeding 5 m within the meaning of Council Directive 82/714/EEC of 4 October 1982 laying down
17、 technical requirements for inland waterway vessels. This standard contains bibliographical references. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this document: Austria, Belgium, the Czech Republic, Denma

19、climbing devices made of steel with a length not exceeding 5 m, used on inland navigation vessels. For the purposes of this standard the term permanently installed climbing devices covers ladders, step irons, dog step ladders and integral treads including handholds. This European Standard does not a

25、Figure 2 3.3 dog-step ladder climbing device consisting of a number of rungs located on top of one another in the vertical axis, see Figure 3 3.4 integrated tread climbing device consisting of rungs installed in a number of vertically alternating cut-outs in a wall, see Figure 4EN 13574:2001 (E) 5 3

27、ounted directly on walls parallel to them 4 Safety requirements 4.1 General General tolerances: ISO 2768-c according to EN 22768-1. Permanently installed climbing devices shall be constructed in a way that avoids injuries, getting caught and an unsure foothold when mounting them. All the treads form
28、ing such a climbing device shall be uniform as shall the distances between the treads. The distance between the topmost tread and the top access of the climbing device shall not exceed 150 mm, the distance between the lowest tread and the access at the low end should correspond to the distances betw
29、een treads, but shall be between 100 mm and 300 mm, see Figure 1. Table 1 Designation of items in Figures 1 to 4 Item Designation Comment A Rung see 4.8 B Spar see 4.7 C Holder see Figure 1 D Handhold see 4.10 E Rung for walls see 4.9EN 13574:2001 (E) 6 4.2 Ladders Dimensions shall conform to Figure
30、 1. The maximum vertical inclination of ladders shall not exceed 15 to allow easy mounting. They shall not overhang. The top and low ends of the spars shall be connected to walls and floors to prevent getting caught. Dimensions in millimetres Figure 1 Ladder with handholdEN 13574:2001 (E) 7 4.3 Step
31、 irons Dimensions shall conform to Figure 2. Dimensions in millimetres Figure 2 Step ironsEN 13574:2001 (E) 8 4.4 Dog-step ladder Dimensions shall conform to Figure 3.

32、mensions in millimetres Figure 4 Integrated treads with example for welded pockets 4.6 Cross-over for coupled vessels If deck levels are different, cross-overs for coupled vessels are required to allow safe crossing between vessels in pushing formation. Cross-overs for coupled vessels shall be insta
33、lled on those sides of the pushing shoulder which are closer to the longitudinal axis of the ship. Cross-overs for coupled vessels shall be constructed as stairs. If this is not possible: cross-overs for coupled vessels shall be constructed as integrated treads or step irons if the pushing shoulder
34、has a closed profile; the dog-step ladder design shall be selected if the pushing shoulder is constructed as an I-bar, see Figure 3. 4.7 Spars Spars shall be constructed so as to ensure safe holding. The dimensions shall conform to Figure 1.EN 13574:2001 (E) 10 4.8 Rungs Rungs shall be constructed s
35、o as to ensure safe holding. They shall have a square profile tilted at an angle of 45 that shall be between 20 mm and 30 mm thick. 4.9 Rungs for walls Rungs for walls shall conform to EN 29519 Form A. 4.10 Handhold The upper access of the climbing device shall be provided with a handhold to enable
36、sure crossing-over from the climbing device to the access and vice versa. A round profile having a diameter of 20 mm to 34 mm shall be used. If the handhold is mounted directly on deck, dimensions shall conform to Figure 1. For cross-overs between coupled vessels conforming to 4.6 and for climbing d
37、evices giving access to cargo holds, handholds are not necessary if the cargo hold coaming ensures safe holding. Instead of handholds, vertical tube constructions may be used that rise at least 1,15 m above the top step. 4.11 Strength Dimensions and welds of the rungs and handholds shall be such tha
38、t they withstand a load of 1,0 kN. The breaking safety shall be 5:1. Dimensions and welds of spars and handholds shall be such that they withstand loads of 1,5 kN per every 2 m of ladder without permanent deformation. These loads shall be applied at the structurally weakest points. 5 Material 5.1 Ge
39、neral Climbing devices made of steel shall conform to 5.2 and 5.3. 5.2 Semi-finished products The rungs shall be made of square steel conforming to ISO 1035-2. The spars and holders shall be made of flat steel conforming to ISO 1035-3. The handholds shall be made of round steel conforming to ISO 103
40、5-1 or steel tubes to ENV 10220. NOTE In cargo holds of tank vessels only solid material should be used. 5.3 Steel quality The rungs, spars, holders and handholds shall be made of steel Fe 360 conforming to ISO 630 as the minimum quality. NOTE As an alternative, shipbuilding steel with comparable me
41、chanical and welding properties may be used.EN 13574:2001 (E) 11 6 Designation Climbing devices may be constructed conforming to the types as given in Table 2: Table 2 Types of climbing devices Climbing devices Type Ladder L Step irons G Dog-step ladder S Integrated treads A Cross-over for coupled v
