The galvanized 3-D hoist rings of H8 chain quality developed by Eickhoff (6 versions with load capacities from 1000 to 8000 kg) meet the requirements of DIN standards 5687, 5688 and the German mining industry standard RAG 726470. Three versions of hoist rings with capacities from 1000 to 3200 kg are also certified by the BG (Deutsche Berufsgenossenschaft).
The hoist rings can be screwed into blind bores or together with additional hex nuts (minimum grade 12.8) can be used with through bores.
Each attachment point carries the load with a safety factor of 4 against breakage in all permissible load directions. It can rotate (360°) and swivel (180°) for automatic adoption to the direction of pull, preventing chain twist and possible breakage. |
