INOX-STAR ring bolt

Patented world novelties of RUD: INOX-STAR

Industrial machinery directives mandated across the European Union require appropriate installations for safely lifting, swivelling, and turning certain heavy constructions, an important stipulation that is too often neglected by mould makers and users. In addition, according to the directives, lifting points and suspension assemblies should allow all-side loading, with a 4:1 design factor protecting against breakage; should be stainless, lacking sharp edges, and lightly constructed; and should offer simple attachment of the lifting appliances-hooks, for example-without extraneous components. All of these stringent industrial requirements, and many others as well, are met by the Inox-Star ring bolt offered by RUD Ketten Rieger & Dietz GmbH & Co. KG.

The shape of the Inox-Star bolt resembles that of the DIN eye bolt, but its pentagonal design is distinctive. Once the special bolt has been tightened, the ring body can still be turned and adjusted for any load direction, making possible a 50% higher working load limit than the conventional DIN eye bolt can boast.

The drop-forged body and captive-mounted special bolt of the Inox-Star are made of duplex steel 1.4462. Both the body and the bolt have been 100% inspected for cracks. Frequently used lifting points must be examined periodically for wear. With the Inox-Star, this is facilitated by the special wear marks on the inner side of the ring body. Currently, RUD can supply standard M12/16/20/24 units with load limits ranging from 600 to 2,600 kg. Upon request, points up to size M36 and with a load limit of 8 tonnes can be produced in stainless steel. RUD offers an extensive range of lifting points for safe handling of machines during manufacturing.
