22、fshore container to the lifting appliance. This can comprise one or multi leg slings (with or without a top leg) and shackles, whether assembly secured or not. EN 12079-2:2006 (E) 5 3.2 assembly secured shackle A shackle fitted to a sling leg and secured by a seal or similar device, so as to signal
23、unambiguously, whether or not the shackle has been exchanged 4 Symbols R the rating i.e. the maximum gross mass of the container including permanent equipment and its cargo, in kg but excluding the lifting set; T the tare mass i.e. the mass of an empty container including any permanent equipment but
24、 excluding cargo and lifting set in kg; P the payload i.e. the maximum permissible mass of cargo which may be safely transported by the container, in kg; NOTE 1 P = R - T NOTE 2 R, T and P are, by definition in units of mass, kilograms (kg). Where design requirements are based on the gravitational f
25、orces derived from these values, those forces are indicated thus: Rg, Tg and Pg the units of which are in newtons or multiples thereof. TDthe design air temperature, i.e. a minimum reference temperature used for the selection of steel grades used in offshore containers and equipment expressed in deg
26、rees centigrade; S mass of the lifting set, in kg 5 Technical requirements 5.1 General requirements 5.1.1 Slings shall be rated for their intended angle of use. In all cases four leg slings shall be rated as for three leg slings. In no case shall a sling be rated for an angle of the sling leg to the
27、 vertical in excess of 45 NOTE For specific angles less than 45 the sling may be rated at the WLL according to the particular angle of the legs to the vertical. This should be calculated by the formula: For two leg slings used at an angle to the vertical, the working load limit should be given by th
28、e formula WLL = 2 x WLL for a single leg x cos . For four leg slings used at an angle of any leg to the vertical, the working load limit shall be given by the formula WLL = 3 x WLL for a single leg x cos . For chain slings this is in accordance with the alternative method of rating in EN 818-4:1996,
29、 Annex A. 5.1.2 Where two 2-leg slings are selected to function as a 4-leg sling, they shall be calculated as for a 4-leg sling. 5.1.3 Hinge type coupling components shall not be used. NOTE This restriction is to avoid the possibility of the coupling seizing in the folded position due to corrosion a
30、nd subsequently failing when forced straight under load. EN 12079-2:2006 (E) 6 5.2 Dimensions and strength of lifting Sets 5.2.1 To allow for the dynamic amplification that will be experienced in offshore lifting in adverse weather and sea states, the working load limit of the lifting sets for offsh
31、ore containers shall be determined using Annex A. Except for containers with ratings below 2000 kg, the container rating R shall be multiplied by an enhancement factor to give the WLL min of the lifting set. For intermediate container ratings the working load limit values shall be interpolated. 5.2.
32、2 The minimum working load limit (WLL min) from Annex A shall be used for determination of the nominal size of the lifting set. NOTE It is recommended that the master link to be attached to the crane hook shall have minimum dimensions 270 mm x 140 mm, internal. 5.2.3 The minimum working load limit o
33、f each shackle (WLLs) shall be calculated as given in Table 1. Table 1 Required minimum shackle working load limit (WLLs) Required minimum shackle working load limit (WLLs) 4 leg sling 2 leg sling Single leg sling WLL min / (3 x cos ) WLL min / (2 x cos ) WLL min where is the angle of the sling leg
34、from the vertical and WLL min is the minimum WLL determined from Annex A 5.2.4 The lifting set shall be of sufficient length to allow easy handling by operators. The top link or master link shall be able to reach down to a height of no more than 1.3m above the container bottom when the sling hangs o
35、ver the long side of the container. 5.3 Chain slings 5.3.1 Chain slings shall meet all requirements of EN 818-4. 5.4 Wire rope slings 5.4.1 Wire rope slings shall meet all requirements of EN 13414-1 with restrictions as applied in 5.4.2 and 5.4.3. 5.4.2 Wire rope shall be 6-stranded and of one of ty
36、pe 6 x 19 or 6 x 36. 5.4.3 The termination of wire rope shall be a ferrule secured thimble. NOTE As an aid to in service inspection, ferrules which permit the tail end of the rope to be visible are recommended. 5.4.4 Wire rope grade 1770 or 1960 shall be used. The working load limit shall be calcula
37、ted on the basis of the actual rope grade used. NOTE This also applies when slings are rated and marked in accordance with the note in 5.1.1 EN 12079-2:2006 (E) 7 5.5 Shackles 5.5.1 Shackles shall meet all requirements of EN 13889 or EN 1677-1 with the additional requirement that the tolerance on th
38、e nominal diameter of the shackle pin shall be 0 + 3 %. 5.5.2 Shackles shall be restricted to: bolt type pin with hexagon head, hexagon nut and split cotter pin; 5.6 Materials 5.6.1 Impact Testing Steels shall be impact tested by the Charpy impact (V-notch) method in accordance with EN 10045-1. The
39、impact test temperature shall be equal to the design air temperature TD and the minimum average impact energy shall be 42 J. However, for welded components (chains, links, rings) it shall be sufficient only to take impact test samples in the weld with the notch centred in the fusion line. The positi
40、on of the weld shall be accurately identified by etching with a suitable reagent before cutting the notches. The minimum average impact energy of the weld shall be 27 J. Where the cross section of the material to be tested is too small to allow the standard test specimen to be taken (10 x 10 mm), th
41、e required energy values shall be reduced as follows: 10 mm x 7.5 mm : 5/6ths of the above value; 10 mm x 5.0 mm : 2/3rds of the above value. NOTE For tests where the size of the test piece is too small (diameter less than 13 mm), tests may be carried out on sample material which shall be of the sam
42、e specification and heat treatment. 5.6.2 Welding In addition to the requirements of EN 818-4, qualification of the welding process shall be in accordance with EN ISO 15613. 5.6.3 Materials used in wire rope slings Materials in wire ropes, ferrules and thimbles shall be in accordance with applicable
43、 standards. 5.6.4 Galvanising Galvanising shall only be carried out under the control of the manufacturer of the component. 5.6.5 Material certificates. The materials used in all components shall be supplied with an inspection certificate to either EN 10204 type 3.1 B or, in the case of materials in
44、 ferrules and thimbles, to EN 10204 type 2.2 with content as detailed in Clause 6. EN 12079-2:2006 (E) 8 6 Certification 6.1 Preparation of certificates Certificates provided in support of claims of compliance with the requirements of this European Standard shall be prepared in accordance with EN 10
