Types of Chain SlingsChain slings come in single leg, 2-leg, 3-leg and 4-leg configurations. Each assembly can be tailored by number of legs, chain dimension, type of hook, and chain length. Assemblies are made in the USA with direct oversight provided. Every component offers traceability with appropriate markings. Adjustable chain slings are also available. These slings are manufactured with shortening hooks on the master link that allow the legs to be shortened without a reduction in load capacity (WLL) due to 4-fold safety. The signal violet color slightly varies between the chain and the fittings due to the thick powder coating the components have, versus the spray painted coating of the chain.
Eric JapengaWhen choosing a sling for your application, US Cargo Control Sales Specialist Eric Japenga suggests starting with determining the amount of weight your lift will cover. After you know your load's weight you can identify how many legs you’ll need, then the diameter of the chain. Japenga says with lower-weight lifts that do not require much stability, a one-legged sling should do the job. Add another leg to handle more weight. For the heaviest lifts, a three-legged sling offers the highest working load limit (WLL). You can add a 4th leg that will add stability, although it will not increase the WLL above the 3-legged sling.
Adding Fittings to Your Chain SlingWhen it comes to choosing the type of hook for your sling, Pewag offers the following guidelines:
KWB Clevis Sling Hook
- Grab hooks are typically used in choke applications
- Clevis hooks do not require a connector hook, and are their most popular style
- Sling hook with latches offer an added safety feature and are OSHA compliant
- Eye hooks need a connecting link and can also be used with wire or synthetic rope
- Self-locking hooks offer greater safety than latch hooks because these latches must be released manually
- Swivel hooks are versatile and do not swivel under load
- Foundry hooks are used when you need a larger mouth opening, however it should be noted that before using this type of hook, check whether hooks without safety latches are allowed for your application
