3、rldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented o
4、n that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopt
5、ed by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard IS0 7061 was prepared by Technical Committee lSO/TC 8, Shipbuilding and marine struct
6、ures. This second edition cancels and replaces the first edition (IS0 7061 :I 9831, which has been technically revised. Q IS0 1993 All rights reserved.

It doe
9、s not apply to gangways for inland navigation vessels. 1.1 This International Standard applies to gangways designed to be carried on board ships, to provide a lightweight, convenient and safe means of access from ship to shore, for use primarily by the ships crew. These gangways may also be used for
10、 access from ship to ship when conditions are favourable. 1.2 This International Standard applies to gangways suitable for use horizontally or inclined up to an angle of 30“ from the horizontal. For angles of inclination greater than 30, special consideration of the design of treads and decking may
11、be necessary. 1.3 The gangways to which this International Stan- dard applies are not intended to carry wheeled traffic such as loaded trolleys. NOTE 1 Users of this International Standard, while o b serving the requirements of the standard, should at the same time ensure compliance with any statuto
12、ry require- ments, rules and regulations applicable to the individual ship concerned. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publi- cation, the editions indicated we
13、re valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most re- cent editions of the standards indicated below.

34、osion. 6.1.3 If the gangway is for use on tankers or ships suitably surface-coated at the possible points of con- tact to prevent sparking. carrying flammable cargo, it shall be provided with an effective and marked earthing device, and shall be 6.2 Design loading The assembled gangway shall be desi
35、gned2to with- stand a uniform decking load of 4 O00 N/m applied to the decking and treads while the gangway is in a horizontal position. 6.3 Factor of safety The allowable stress used in the design of the gangway as specified in 6.2 shall be determined by applying a factor of safety of 2 on the 0,2
36、% proof stress of the aluminium alloy used. 6.4 Side stringers Side stringers shall be constructed from extruded hollow section, rolled section, plate material or any combination of these. 6.5 Cross-members Cross-members attached to the side stringers shall be arranged to support the decking, and sh
37、all be of bar, angle or hollow sections. 6.6 Decking topped longitudinal corrugated section, or individual flat plate section, which shall have a non-slip coating applied between the treads. The decking shall comprise either continuous flat- 6.7 Treads Treads shall be of aluminium bar or rectangular
38、 hollow section, or of hardwood, and shall be spaced at reg- ular intervals of 300 mm to 400 mm longitudinally. Treads shall have a minimum height of 30 mm above the decking; hardwood treads shall have a minimum section width of 40 mm in contact with the decking. All treads shall be securely fitted,
39、 and shall extend over the full width of the gangway between the toeboards.

Water shall not gather between the treads. 6.8 Stanchions Stanchions shall be constructed from carbon steel or aluminium to comply with figure
41、 1. They shall be fitted at regular intervals along the gangway, with a maxi- mum permitted interval of 1 500 mm. Stanchions and associated hand guides shall be designed for a side loading at the upper guide level of 500 N/m, without permanent deformation to stanchions or rigid hand guides when used
42、. Stanchions of one of the following types may be fitted: a) permanently fixed; b) hinged, with provision made to prevent inadver- tent collapse; c) portable, with securing device to prevent acci- dental displacement from the socket or base sup- port. Galvanized stanchions, where specified, shall co
43、mply with the requirements of IS0 1459, IS0 1460 and IS0 1461. 6.9 Hand and intermediate guides Hand and intermediate guides shall be provided to comply with figure1 and shall be selected from one of the following types: a) continuous and adequately tensioned sisal, manila, polypropylene or plastics
44、-covered wire rope, hav- ing a minimum rope diameter of 16 mm; b) continuous rigid aluminium solid or hollow section. In case of fibre rope or wire rope rails, a way to re- tighten such rails should be provided. Polypropylene ropes shall be certified effective against actinic degradation for two yea
45、rs exposure in tropical conditions. 6.10 Toeboards Toeboards shall be fitted to each side of the gangway to a minimum height of 150 mm. 6.11 Roller or wheels A roller or wheels of 100 mm minimum outside di- ameter shall be positioned at one end of the gangway. Rollers and wheels shall be provided wi
46、th self- lubricated bearings or fitted with lubrication nipples to IS0 3799 specifications having a thread MI O x 1. To IS0 7061:1993(E) ensure protection of users feet from movement of the gangway, roller or wheel guards shall be provided. At the maximum angle of use of the gangway there shall be n
47、o loss of contact between the roller or wheels and the contact surface. 6.12 Securing device attachments Suitable attachments shall be provided at appropriate points on both sides of the gangway, in order to con- nect the securing devices (see figure 1). 6.13 Lifting lugs The gangway shall be provid
48、ed with four lifting lugs, securely attached to the side stringers and positioned to produce a balanced lift. 6.14 Anti-slip lugs The gangway shall be provided with anti-slip lugs securely attached to the side stringers, and positioned to prevent the gangway slipping from its position on the bulwark
49、s or other supporting structure. 6.15 Protection against corrosion and rot Steel parts of the gangway shall be provided with anti-corrosion coatings. If contact of dissimilar metals cannot be avoided, the surface of contact shall be protected particularly carefully. Wooden parts of the gangway shall be suitably pro- tected against rot and fungi. 6.16 Rope net In some countries, a safety net is required: in these cases, it shall be spread underneath the gangway. 7 Quality of manufacture 7.1 The assembly, comprising side stringers, cross- members and decking, together with al
