Chain Slings & Lifting Chains
Chain slings and lifting slings are ideal for applications when extra strength and durability is required. Not only are chain slings more durable, temperature tolerant, and cut resistant than nylon web slings or polyester round slings, there are also options for chain rigging slings to be adjustable and customized.
Grade 100 Chain Slings
Grade 100 is becoming the industry-standard grade for chain sling manufacturing. Safe for overhead lifting, this alloy chain features exceptional strength and meets U.S. standards of NACM, ASTM and OSHA. It’s 25% strong than Grade 80, the next level down.
Chain Sling BrandsWe offer two trusted brands of lifting chain slings for you to choose from: Crosby and KWB.
CrosbyCrosby has been a leader in the rigging and lifting industry for years and takes no shortcuts when it comes to manufacturing chain and rigging hardware. The Crosby chain slings we sell are manufactured right here in the USA and expertly assembled by US Cargo Control.
KWBKWB grade 100 chain slings have a signal violet varnish coat and a heavy powder coating that helps with corrosion resistance. KWB is a Pewag company, based in Europe. We import and expertly assemble their manufactured chain and end fittings into the high-quality chain slings you see here.
Chain sling types
We sell two main types of slings: standard and adjustable. Standard and adjustable slings can be configured a number of ways to ensure they meet the needs of the lift. Several different options are available, including number of legs, size of chain, and length of chain. Custom options for various end fittings are also available by calling our sales team.
Standard chain slingFeatures one, two, three, or four lengths of chain, each with a master oblong link at the top, and your choice of hooks: foundry hook, grab hook, sling hook, or self-locking hook.
Adjustable chain sling.Designed with the same leg configuration as a standard chain sling, but also includes an adjustable fitting. This enables the operator to shorten the length of the leg as needed. For more information on our adjustable chain slings, or to place an order, give our sales team a call.
How is the reach of lifting chains calculated?
A chain sling’s reach is measured length from the load-bearing point on the sling’s master link to the load-bearing point on the opposite end when the sling is pulled taut.
End fitting options for chain slings
The customization of lifting chain slings with various end fittings is what makes industrial chain slings so versatile and appropriate for a wide variety of lifting jobs. Our alloy chain slings are fitted with either a foundry, grab, sling, or self locking hook. Adjustable slings feature an additional length adjusting mechanism. Common end fittings include:
- Sling hook: also known as slip sling hooks, these large throat hooks are commonly used at the ends of chain slings and wire rope. They’re typically self-locking to avoid disconnect.
- Self-locking hook: these hooks are designed to pivot in the middle and lock when lifting pressure is applied. They cannot be opened while lifted with your overhead lifting chains.
- Foundry hooks: these are extra-large throat hooks that are used in unique situations that require a larger opening to manage loads.
- Grab hook: these chain sling hooks have a small throat that attaches to the chain by slinging over the chain in-between links.
- Oblong master link: An oblong shaped ring used at the top of chain slings.
Other types of lifting slings
Overhead lifting chain slings are ideal for a range of heavy duty lifting jobs. If your application requires a different qualities, such as flexibility or stretch, see our entire selection of lifting slings, which includes fabric such as nylon slings and polyester round slings, as well as heavy duty wire rope slings.
If you need help selecting a lift sling, see our How to Choose a Lifting Sling page or call our product specialists. They’ll be happy to any answer questions you have.
Chain sling safety
- Always use within posted working load limit
- Distribute loads evenly;an unequal load on one leg can create a dangerous situation and damage the sling
- Rapid or sudden stops, impacts, and lifts should be avoided
- Do not allow a chain length to be twisted or tied into a knot
- Do not use slings with damaged, defective, or worn chain
- Protect sharp edges and corners accordingly with padding or protectors to keep chain from coming in contact
- Don’t forget to inspect hooks- never use if bent or distorted in any way
- Load hooks should never be tipped or pointed;a latch should never support a load
- Clean chains prior to inspection;oil and dirt can hide chain damage
Standard sling designations
Most chain slings will generally consist of a master link, a chain leg or legs, and a fitting such as a hoist hook. Sling manufacturers use a standardized sling designation using a three letter combination.
- The first letter indicates the number of legs: S=Single Leg, D=Double Leg, T=Triple Leg, Q=Quadruple Leg, C=Single leg with normal chain link on the end with no fitting.
- The second letter indicates they type of master link: O=Oblong Master Link, P=Pear Shaped Master Link, S=Sling Hook, G=Grab Hook.
- The third letter indicates the style of hook: S=Sling Hook, G=Grab Hook, F=Foundry Hook, L=Latchlock Hook, O=Oblong Link
Because we customize the chain sling's configuration, which will vary the work load limit and break strength, our chain slings come with a metal ID tag attached that is stamped with the information below:
- Sling style
- Serial number
- Chain size and grade
- Working load limit at degree of lift
Proof testing has been done on every link of chain to ensure its working load limit. To get your custom chain sling tested at the time of manufacture, it must be requested when the order is placed with our sales specialists. For an additional fee, we will proof test your sling and issue a certificate when requested at the time the order is placed.
All of our chain meets or exceeds the latest guidelines of the National Association of Chain Manufacturers (NACM), ANSI B30.9 standards and OSHA specifications.
Even with proper care, chain will eventually begin to wear over time. It's important to regularly inspect the links of overhead lifting chain for minimum allowable thickness. Once it's worn below this measurement, it should be removed from service.
Heat's effect on chain slings
While sling chain is considered extremely strong and durable, excessive heat can have an effect on the working load limit of a sling. Chain lifting slings used in excess of 400 degrees will experience a reduction in strength, both during exposure time and after exposure. See guidelines below. NOTE: OSHA 1910.184 requires all slings exposed to temperatures over 1000º F to be removed from service.
