BS EN 13414-3:2003+A1:2008 Licensed CopyChinese University of Hong Kong, 13/06/2009 05:16, Uncontrolled Copy, (c) BSI EN 13414-3:2003+A1:2008 (E) 4 Introduction This Part of the standard has been prepared to provide a means of complying with the essential safety requirements of the Machinery Directive and associated EFTA regulations. Purchasers are advised to specify in their purchasing contract that the supplier operates a quality management system applicable to this standard (e.g. ISO EN 9001) to ensure that products claimed to comply consistently achieve the required level of quality. The coefficient of utilization (Zp) used in this standard for slings with a diameter greater than 60 mm is lower than that normally used for general service wire rope slings. This is justified for the following reasons. a) Slings over 60 mm diameter are not intended for general service and are subjected to special conditions relating to design, construction, frequency of use, service and discard. b) The mass of the load is generally calculated or measured with considerable accuracy and as such slings are usually specially manufactured for one or a limited number of special lifts. c) The lifting operation is controlled and supervised. d) The dynamic factors, e.g. shock loading, are limited. These factors reduce the unknown aspects which dictate that slings in general service require a higher coefficient of utilization; lower coefficients have been and are used with confidence. 1 Scope This European Standard specifies the construction requirements, calculation of WLL, testing and certification of steel wire rope grommets, cable-laid grommets and cable-laid slings using strand and wire rope conforming to EN 12385-4. The hazards covered by this standard are identified in clause 4. This standard covers ferrule-secured cable-laid slings up to 60mm. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to, applies.

These aspects of safe use associated with good practice are given in prEN 13414-2. Table 1 contains all the hazards which require action to reduce risk identified by risk assessment as being specific and significant for slings and their components. Table 1 Hazards and associated requirements Hazards identified in annex A of EN 1050 : 1996 Relevant clause of annex A of EN 292-2: 1991/A1: 1995 Relevant clause/sub-clause of this Part of EN 13414 1.1.5 Mechanical hazard due 4.1.2.3 5 and 6 to inadequacy of 4.1.2.5 5 and 6 strength 4.1.2.4 7 4.3.2 7 10.4 Errors of fitting hazard 1.5.4 5 5 Safety requirements and/or measures 5.1 Grommets 5.1.1 Production of grommets During the production of grommets a temporary rigid core shall be used. Grommets and cable-laid ropes shall be produced using a method which ensures that the rope or strand tensions are equalized and that the finished product is free from visible waviness. 5.1.2 Construction of wire rope grommet The strand used to form the wire rope grommet shall be one of those used to form ropes specified in table 2, 4, 6, 8, 11, 12 and 13 of EN 12385-4:2002. The length of the circumference shall be at least five times the grommet lay length. The core butt position shall be clearly marked by red paint applied over any serving. 5.1.3 Construction of cable-laid grommet Cable-laid grommets shall be constructed in accordance with A.1. The unit ropes shall be of 6- or 8-strand construction selected from those specified in tables 2, 3, 4, 5, 6, 7, 8, 11, 12 and 13 of EN 12385-4:2002. Ropes over 60 mm diameter shall have steel rope cores. The length of the circumference shall be at least five times the grommet lay length. The core butt position shall be clearly marked by red paint applied over any servings. NOTE The grommet should never be bent at this marked position.

For wire rope grommets the tolerance shall be ± 1d or 1% of the nominal length whichever is the greater. For cable-laid grommets constructed from unit ropes with a fibre core of 24mm ? d ? 60mm the tolerance shall be ± 1d or 1% of the nominal length whichever is the greater. For cable-laid grommets constructed from unit ropes with a steel core of 24mm ? d ? 60mm the tolerance shall be ± 1d or 1% of the nominal length whichever is the greater. For cable-laid grommets constructed from unit ropes with a steel core of 66mm ? d ? 696mm the tolerance shall be ± 0,5d or 0,5% of the nominal length whichever is the greater. NOTE Two methods of determination of the length of grommets, either by measuring the distance of the bearing points or, more accurately, by measurement of the circumference are described in annex B. For the measurement process pin sizes shall conform to annex C. Figure 1 Wire rope grommet 5.2 Cable-laid slings 5.2.1 Construction of cable-laid sling Cable-laid slings shall be constructed in accordance with A.2. The unit ropes used shall be of 6- or 8-strand construction selected from those specified in tables, 2, 3, 4, 5, 6, 7, 8, 11, 12 and 13 of EN 12385-4:2002. Cable-laid ropes over 60 mm diameter shall have steel rope cores. If the turn-back loop system for terminations is used, it shall conform to prEN 13411-3. Only unit ropes with a steel core shall be used. Splices shall be made in accordance with annex D. 5.2.2 Length of cable-laid slings The length, L, of a sling, shall be the internal length between the bearing points of each termination whether they are soft eyes, thimbles, or hooks or links, as appropriate (see figure 2).
