In lifting equipment (from hand winches to huge industrial cranes) and as an element of the rigging structure, such fastening elements as DIN 689 hooks can be used. This type of hardware has a number of advantages that distinguish it from rigging devices of a similar type. Constructive and operational features of hooks DIN 689 High-strength characteristics. This criterion is achieved by choosing a high-quality material for the production of DIN 689 crane hooks. As a rule, this is high-quality steel, pure carbon or alloyed with additional substances. The properties of this material make it possible to create high-strength hardware by resorting to procedures for improving these characteristics. Convenient design. The composition of the hardware includes three links: an eyelet for pulling a flexible fastening element (a link of a chain, cable, rope, etc.), the steel hook itself, and a movable fuse. The task of the latter is to protect cargo from loosening during transportation or fixing.
