2、 published by the International Organization for Standardization (EO), the comma has been used througout as a decimal marker. Dimensions in mm 1 Field of application and purpose This standard applies to the finished parts of drop forged and hammer forged single hooks with threaded shank, with or wit
3、hout nose, on lifting means and load carrying means of lifting appliances, which are used primarily for the suspension of loads. In this standard, ,power driven series produced lifting appliances“ is understood to cover also appliances which are incorporated in cranes. The correlation of the lifting
4、 capacity of the single hooks to the strength classes and driving gear groups is in accordance with DIN 15400. The dimensions specified for 24 apply to single hooks forming part of a lifting hook suspension conforming to DIN 15 41 1. In the case of single hooks which are exposed to intense heat (e.g
5、. where the conveyance of molten masses is involved), it is recommended adopting laminated hooks conforming to DIN 15 407 Part 1 and Part 2 for single hooks of size No. 20 and above. In this way, it is possible to standardize the finished parts with threaded shank made by different manufacturers. .

21、engths l4 differing from those specified in table 1 be required in exceptional cases, e.g. for use in conjunction with existing lifting appliances, this must be specified on ordering.

22、 M See subclause 2.2 for designation of a single hook with threaded shank in combination with a lifting hook nut and a locking piece. Page 4 DIN 15 401 Part 2 Ring gauge for single hook No. 2.2 Single hooks with threaded shank and nut In view of the need to lock the lifting hook nut and of the machi
23、ning process of the knuckle thread, the single hook and the lifting hook nut are not interchangeable. So, both must be ordered simultaneously. Consequently the only designation examples given are those which relate to single hooks with threaded shank and associated nut. A ring gauge shall be used to
24、 fix the location of the single hook in relation to the lifting hook nut, see figure 6. By this means the common machining of the groove for the locking piece conforming to DIN 15 414 on the single hook and on the lifting hook nut in accordance with DIN 15 413 is made possible, as is also the interc
25、hangeability of the single hook with nut. After finish machining, the ring gauge shall be removed. tl t2 t3 d2 i H: h6 H8 dl E9 Ring 8 10 12 16 Detail V 67 56 58 85 4-5 7 75 64 66 95,5 4s 7 85 72 74 110,5 5.5 8 95 80 82 120.5 63 9 25 32 40 50 I 6 1601 501 52179 14 17 118 1 O0 102 144 8 11 132 110 11
