US Cargo Control has launched a new manufacturing capability with the introduction of KWB Grade 100 signal violet chain slings to their product line. KWB, a Pewag company, is known for their high-quality chain and fittings, while Pewag is a leader in the chain manufacturing industry, known for their innovation and high-quality products.
Chain slings are a powerful tool in heavy-duty overhead lifting applications. They also perform well in situations where excessive heat is an issue, or environmental issues (like chemicals) may be present.
US Cargo Control offers chain slings that are custom-made on-site with Grade 100 alloy chain and fittings. Our Grade 100 chain and fittings are manufactured by KWB, a Pewag company, in a high-visibility signal violet color that is easily identifiable in the field. High-quality and European-made, all KWB products exceed U.S. standards of NACM, ASTM and OSHA. Every link of chain is proof load tested to 2.5 times the WLL.
Grade 100 offers a 25% higher load capacity than G80, with smaller chain dimensions, considerable weight reduction and easier handling.
Types of Chain Slings
Chain 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.
When 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 Sling
When it comes to choosing the type of hook for your sling, Pewag offers the following guidelines:
- 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
When ordering your chain sling, if you require a proof testing certificate, you must request one at the time of order, and a nominal fee will be charged.
