Chain slings are one of the most durable and robust types of rigging available. It is not uncommon to inspect chain slings that have been in service up to 40 years. Industrial lifting slings fabricated from chain offer riggers two important advantages over nylon web slings, polyester round slings and twin-path® slings: wire chain slings are more temperature tolerant, cut resistant and certain options allow chain rigging slings to be adjustable.
Chain is produced in different grades. The larger the lifting chain grade number, the stronger the rigging chain. Grade 30 and 40 chain is sold at many hardware stores and is great for barricading parking lots or defending yourself, but shall NEVER be used for lifting chains. Grade 70 transport chains used by trucking and transportation companies are acceptable for use as tie down chains to tie down loads, but shall NEVER be used for rigging chain lifting slings. The only grades of rigging chain that is acceptable for lifting (not overhead lifting, as you are never on, under, near or next to the load or any rigging that is under tension) are grade 80 lifting chain, grade 100 lifting chain and grade 120 rigging chain. The metal used in Grade 80, 100 and 120 crane rigging slings is designed to stretch and elongate. This is a very important reason for close attention to detail when measuring chain slings during the annual inspection. Up to a few years ago the most common grade of alloy lifting chain used for crane chain slings was grade 80. Recently, most major rigging chain manufacturers are shifting to grade 100 lifting chain, which size for size is stronger and lighter than grade 80 rigging chain. The lifting chain used in the fabrication of your rigging chain slings is quenched and tempered in the wire chain fabrication process. The Chain rigging slings we make and supply meets or exceeds the recommended standards of the National Association of Chain Manufacturers (NACM), ANSI/ASME B30.9 standards and DOL-OSHA regulations.
There are many different type of chain sling fittings that enable the users of industrial lifting slings fabricated from chain access to single leg chain slings, double leg chain slings (also known as two leg chain slings), triple leg chain slings (also known as three leg chain sling bridles) and quad leg chain slings (also known as four legged rigging chain sling bridles). In addition to standard chain sling fittings, custom made fittings and custom made lifting chains are readily available.
Standards that govern the manufacture of chain lifting slings require that either the final assembly or all the individual components used to fabricate rigging chains must be proof tested and certified. We proof test every chain sling we manufacture and provide you with a certificate of test. We do not charge extra for this service.
We are proud to offer the Gunnebo, GrabiQ line of chain rigging slings in addition to wide range of standard industrial lifting chain slings. The GrabiQ chain sling system is simpler and smarter! Instead of the conventional approach where one fitting does on job, GrabiQ crane chain slings and chain sling bridles combine up to three separate functions into a single component. A GrabiQ two leg adjustable chain sling would have ONLY three fittings. The GrabiQ, master grab serves with built in adjustment hooks, serves as a master link, a connector for the rigging chain sling legs and also allows adjustment for the chain sling legs, IN ONE FITTING. To put it into perspective, a GrabiQ double leg adjustable rigging chain sling bridle has a total of ONE fitting. A conventional, double leg adjustable chain sling bridle would have SEVEN fittings. The difference is even more dramatic when you consider the same comparison for a four leg adjustable chain sling bridle. A GrabiQ four leg adjustable rigging chain sling bridle has a total of THREE fittings. A normal double leg adjustable chain crane sling bridle would have THIRTEEN fittings. To view the radical difference, see page 170 in our Resource Guide.
Anyone given the choice, would automatically opt for the GrabiQ lifting chain sling by answering two questions:
Which chain sling bridle is lighter? Which rigging chain bridle sling is easier to inspect?
There are many unique fittings that make up the GrabiQ chain sling system. Top fittings are: Master Grab (MG) for single leg sling rigging chains and Master Grab Dual (MGD) for two lifting chain leg slings. The Master Grab and Master Grab Dual combine master link, connector and shortening functions into one fitting. Oblong master links (MF) can be used for 1, 2, 3 or 4 leg chain slings when C-Grab or C-Lok lifting chain sling connectors are used. Oblong master links (MFX) can be used as the top connector for 1 leg or 2 leg chain sling assemblies when used with C-Grab or C-Lok connectors. The oversized masterlink with sublink (MTX) is used as the top connector for 3 leg or 4 leg chain sling assemblies with C-Grab or C-Lok connectors.
GraiQ connector components are used with MF, MFX or MTX master links to form up chain sling bridle assemblies.
The GrabiQ C-Grab (CG) is used as a connection to a masterlink for a single leg chain sling and can also be used as a sliding choker hook. The C-Grab has a built in chain pocket for shortening or creating leg loops. The GrabiQ C-Grab Dual (CGD) functions like the C-Grab, except it connects two legs of lifting chain to the MF, MFX or MTX masterlinks. C-Lok (CL) hooks are used with the GrabiQ masterlinks to attach one leg of chain and can also be used as a sliding choker hook.
C-Lok Dual (CDL) is a GrabiQ connector link used to attach two legs of crane chain sling to GrabiQ master links.
GrabiQ hooks are also readily available as the fitting that connects the chain sling to the load. EGKN sling hooks are one of the most popular fittings. The GBK self-locking hook features a protected grip latch that locks in the hook point.
GrabiQ swivel hooks are also available. LBK Swivel eye features a grip latch and a bushing that allows hook rotation BEFORE the load is applied. The LKBK swivel eye grip latch hook has a ball bearing that allows the hook to swivel under load. The EGKN GrabiQ clevis sling hook is also a very popular chain rigging sling hook.
GrabiQ top assemblies are available for non-adjustable and adjustable rigging chain sling assemblies. Top L Top Lok (TL1) is for single leg or 1 leg chain rigging slings that are not adjustable. (TL2) is for double leg or 2 leg crane chain slings that are not adjustable. Top Lok (TL3) is for triple leg or 3 leg chain rigging slings that are not adjustable. Top Lok (TL4) is for quadruple leg or 4 leg chain slings that are not adjustable. If adjustable chain sling bridles are desired, GrabiQ Top Grab assemblies can be used. Top Grab (TG1) is for single leg or 1 leg wire chain slings that are fully adjustable. Top Grab (TG2) is for double leg or 2 leg lifting chain slings that are fully adjustable. Top Grab (TG3) is for triple leg or 3 leg rigging chain slings that are fully adjustable. Top Grab (TG4) is for quadruple leg or 4 leg chain crane slings that are fully adjustable.
GrabiQ components also enable the use of single basket chain slings and double basket chain sling assemblies that are non-adjustable, adjustable from one side and/or adjustable from both sides. The BS single basket chain sling is not adjustable. GrabiQ BSG single basket chain sling assemblies are adjustable from one side. The single basket type BSGG is a single leg basket sling that is adjustable from each side. Double basket chain sling assemblies are available as a non-adjustable chain sling Double Basket (DB). For a double basket chain sling that is adjustable from one side, specify:Model BDG. For additional versatility, the double leg basket chain sling is adjustable from either side.
GrabiQ MIG Midgrab shorteners are another innovative way to adjust the length of chain sling legs. The midgrab shortener can instantly positioned on any part of the chain sling leg or set idle when not in use. For a visual overview of the more popular GrabiQ chain sling assemblies see page 174 in our Resource Guide.
Chain slings that utilize standard chain sling fittings and components are also readily available. Single leg chain slings and chain slings with 2, 3 or 4 legs are manufactured and proof tested at Lift-It Manufacturing. It is important for you to consider if you require a non-adjustable lifting chain sling or an adjustable rigging chain sling bridle. Master links and masterlinks with subassemblies are used as top lifting fixtures. Alloy coupling links and chain sling couplers similar to hammerloks and lok-a-loy coupling links are used to connect the lifting chain sling legs to the oblong, top link. A vast selection of chain sling hooks is available to fit most every application. We can provide custom made fittings as components in custom made chain sling bridles. Sling hooks with half links, eye sling hooks with recessed latches, foundry hooks, eye grab hooks, clevis grab hooks and sliding choker hooks for chain slings are stocked for the immediate shipment of your wire chain bridles and chain sling assemblies. Eye type self-locking hooks with grip latches and eye type self-locking hooks with bronze bushings allow for the hook to rotate while under load are also readily available. Some applications require an alloy weld on hook. Alloy weld on hooks are available from 3/4 ton to 15 ton capacities.
For a complete overview of the most popular lifting chain sling and assemblies in single leg, double leg, triple leg and quad leg designs see pages 185-186-187-188 in our Resource Guide. You will also see Endless Basket Slings and Double Endless Basket Slings, as well as adjustable and non-adjustable chain rigging slings.
Another novel approach to adjustable chain slings comes in the form of a Slingmax® chain sling saddle ring. Chain sling saddle rings provide quick adjustment and are more economical, lighter and more versatile than conventional adjustable chain sling assemblies. Single slot rings are used for single leg and double leg lifting chain sling configurations. The double slot chain saddle ring is used for triple and quad leg rigging chain slings.
It is important to realize that chain slings can be damaged and can fail resulting in injury, death and/or property damage. It is extremely important that sling users are trained in proper use and inspection techniques. We offer training opportunities at our Learning Center in Pomona, CA on a monthly basis and encourage all sling users to read and understand the warnings that accompany all our rigging gear, hoisting equipment and/or industrial lifting slings.
