Dimensions in mm 1 This standard applies to the finished parts of drop forged and hammer forged ramshorn hooks with threaded shank, with or without nose, on lifting means and load carrying
3、 means of lifting appliances, which are used primarily 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. In the case of ramshorn hooks which are exposed to intense heat (e.g. wh
4、ere the conveyance of molten masses is involved), it is recommended adopting laminated hooks conforming to DIN 15 407 Part 1 and Part 2 for ramshorn hooks of size No. 20 and above.
