21、ard has been prepared as round steel link studless anchor chains as specified in EN 14330 with a pitch of 2,8 d have proved successful 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 p

22、assage of accessories, in particular, Kenter-type joining shackles as specified in EN 14606. Cable lifters for stud-link anchor 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 specif

31、l 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 desi

32、gn 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 to E

33、N 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, see An

34、nex 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.
