17、 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of an identical text or by endorsement, at the latest by May 2006, and conflicting national standards shall be withdrawn at the latest by May 2006. According to th
18、e CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxemb

EN 14874:2005 (E) 4 Introduction This European Standard has been prepared as round steel link studless anchor chains as specified in EN 14330 with a pitch of 2,8 d have proved s
20、uccessful with the accessories specified in EN 14606 in inland navigation. The cable lifter is designed for round steel link chains as specified in EN 14330, but not for the passage of accessories, in particular, Kenter-type joining shackles as specified in EN 14606. Cable lifters for stud-link anch
21、or chains are standardized in ISO 21. 1 Scope This standard applies to cable lifters for round steel link chains according to EN 14330 for inland navigation vessels. It specifies requirements, dimensions, materials, the designation and testing. 2 Normative references The following referenced documen

29、 steel link chain does not spring out nor slide, or if it does, only slightly, between the teeth. Safe lifting or lowering of the anchor requires an angle of contact of 110 at least and more than two teeth engaged according to EN 13711. NOTE 1 The theoretical reference diameter D0is important in the
30、 design of the windlass drive or capstan drive. NOTE 2 In order to ensure the safe passage of the round steel chain link from the cable lifter into the chain locker, a suitable device, e.g. chain projector or raised hawse pipe may be provided. 4.2 Material Grey cast iron, symbol EN-GJL 200 according
31、 to EN 1561. 4.3 Number of teeth The cable lifter shall have at least five teeth. 4.4 Dimensions The cable lifters and the teeth profiles need not correspond to the design illustrated, compliance is only required with the dimensions given. For calculation principles for determining the dimensions, s
32、ee Annex A. For general tolerances for cast iron, ISO 8062-CT 12 shall apply. For general tolerances for mechanical finishing, class m of ISO 2768-1 shall apply. For dimensions, see Table 1.
