Chain Sling Types Crosby® Grade 80 Chain Sling Configurations TO MAKE YOUR CROSBY SPECTRUM 8® ALLOY CHAIN SLING If measurement comes in the link, cut the following link. For two leg type slings, count the links and use an even number for clevis hooks and an odd number for eye hooks. This will position hooks in the same plane. In multileg slings always use the same number of links in each leg. Follow these simple steps in making a sling assembly: 1. Determine the maximum load to be lifted by the sling assembly. 2. Choose the type of sling assembly suited for the shape of the load and the size of the sling assembly for the load to be lifted. The decision must take into account the angle of the sling legs in multileg slings. When using chain slings in choker applications, the Working Load Limit must be reduced by 20%. Crosby recommends a minimum angle of choke of 120 degrees. Consult Crosby when planning to use an angle of choke of less than 120 degrees. If Crosby A-1338 cradle grab hooks are used at a minimum angle of choke of 120 degrees, the full sling rated WLL can be utilized. 3. Determine the overall reach for bearing point of master link to bearing point on hook. (see Fig. 1) 4. Select components, assemble chain and components. 5. Affix sling identification tag to sling. The tag is available from your Crosby Distributor. Each sling shall be marked to show: name or trademark of manufacturer, grade, nominal chain size, number of legs, rated load for the type(s) of hitch(es) used and angle upon which it is based (reach). In shortening applications, a 20% reduction of the Working Load Limit is required except when using the Crosby A-1338 cradle grab hooks or S-1311 chain shortener link. They can be used without any reduction to the Working Load Limit. The Slings shown here are standard assemblies that can be made from “Proof Tested” Crosby Components and Alloy Chain supplied by your authorized Crosby distributor. Assemblies must include SLGID chain sling identification tag (not shown, see page 204). of The Crosby Group, Inc., General Catalog 2008).
