1、UDC 621.86.061.1 DEUTSCHE NORM November 1982 DIN 15 402 Lifting hooks for lifting appliances Ramshorn hooks Part 1 Unmachined parts Lasthaken fr Hebezeuge; Doppelhaken; Rohteile Supersedes July 1970 edition 4s it is current practice in standards published by the International Organization for Standa
2、rdization (JSO), the comma bas been used throughout as a decimal marker. Dimensions in mm 1 Field of application and purpose This standard applies to drop forged and hammer forged unmachined parts with or without nose for ramshorn hooks on lifting means and load carrying means of lifting appliances,
3、 which are used primar- ily for the suspension of loads. The correlation of the lifting capacity of the ramshorn hooks to the strength classes and driving gear groups is in accordance with DIN 15 400. The dimensions specified for II apply to ramshorn hooks forming part of a lifting hook suspension c
4、onforming to DIN 15 41 1. If in exceptional cases, e. g. for existing lifting appliances, different lengths I1 are needed, this must be mutually agreed on ordering. In the case of ramshorn hooks which are exposed to intense heat (e. g. where the conveyance for molten masses is involved), it is recom
5、mended adopting laminated hooks conforming to DIN 15 407 Part 1 and Part 2 for ramshorn hooks of size No. 20 and above. In this way. it is possible to standardize the unmachined parts of ramshorn hooks made by different manufacturers. 2 Dimensions, designation See pages 2 and 3 for illustrations, de
6、signations and tables of dimensions. 3 Material The specifications of DIN 15 400 shall apply. Ramshorn hooks conforming to this standard should predominantly be of strength classes M or P. 4 Finish Surface finish: forged and descaled. Permissible deviations: in accordance with tables 2 and 3. Local
7、indentations are permissible on the hook shank and on the transition to the curved back. The nega- tive deviation for such indentations shall be half of the positive deviation for dl in accordance with tables 2 and 3. See DIN 15 402 Part 2 for finished parts with threaded shank. 5 Technical delivery
8、 conditions The specifications in accordance with DIN 15 404 Part 1 shall apply. Continued on pages 2 to 4 Soie sale rights of German Standards (DIN-Normen) are with Beuth Veria0 QmbH.
