Chain Slings for Industrial Applications

The production process of a chain sling starts with steel wire, which is bent in a bending machine to interwoven chain links forming a chain at the end. Subsequently the gap in every single link is going to be welded. To ensure safety, 100% of the welded chain will be mechanically calibrated, the force exceeding the minimum proof force M.P.F., thus the chain is completely proof loaded. In order to fulfill the purpose of every chain sling additional components are necessary. For fixing the chain sling to the load a clevis hook, a joining link with eye hook, transition link and shackle is assembled at one end of the chain. On the other end an oblong master link completes the chain sling. An identification tag with the appropriate working load limit is fitted on this master link. Only proof tested items are used for the production.

Due to the fact the chain sling serves as a connection between load and load hook it has to go with the form and the load of the load. Therefore lifting different kind of loads can create different tasks. Even though it is not possible to manufacture chain slings in a universal way there are some possibilities to increase the versatility of the slings. For example individual chain slings can be mounted by means of releasable connections. In order to avoid an incorrect assembly of the individual parts which leads to a reduction of the identified and secured working load limit, special confusion proof connection links are being used. Your investment gives you greater versatility. The Ketten Wälder chain configurator automates the compilation of chain slings, being a handy tool for your everyday requests using eight parameters.
