Chain lifting slings are ideal for applications when extra strength is required, or environmental hazards such as chemicals or excessive heat may be present.
Chain slings are also an excellent choice if customization is required. Standard and adjustable slings can be configured a number of ways to ensure they meet the needs of the lift.
Grade 100 Chain Slings
Grade 100 is becoming the industry-standard grade for chain sling manufacturing. We manufacture grade 100 chain slings using signal violet chain and signal violet fittings from KWB, a Pewag company. Safe for overhead lifting, this alloy chain features exceptional strength and meets U.S. standards of NACM, ASTM and OSHA. Every link of chain is proof load tested to 2.5 times the WLL.
All of our chain slings for lifting are manufactured in the USA with high quality European chain and fittings for superior quality.
Chain sling types
We sell two main types of slings: standard and adjustable. 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 toll free at 800-969-6543.
Standard chain sling. Features one, two, three, or four lengths of chain, each with a sling hook with latch at the end, and attached to a master oblong link at the top.
Adjustable chain sling. Designed with the same leg configuration as a standard chain sling, but also has one-four 6 inch lengths of chain with a grab hook also attached to the oblong. 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 at 800-969-6543.
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.
The customization of lifting chain slings with various end fittings is what makes sling chain so versatile and appropriate for a wide variety of lifting jobs. Our alloy chain slings are fitted with a latched sling hook on the legs and grab hooks on the shorter legs of the adjustable slings, but different hook types are available by calling our sales team at 800-969-6543.
Common end fittings include:
Slip sling hook
A large throat hook used primarily at the ends of chain slings. Usually self-locking to avoid disconnect.
Grab sling hook
A small throat hook that attached to the chain by sliding over the chain in between links. This hook locks into place by grabbing the chain, and will not slide along the chain.
An extra-large throat hook used in unique situations that require a larger opening to manage loads.
Self-locking sling hook
Designed to pivot in the middle and locks when lifting pressure is applied. This hook cannot be opened while unit is lifted with your overhead lifting chains.
Oblong master link
An oblong shaped ring used at the top of chain slings.
We also sell bulk chain in grade 70 chain, grade 80 chain, grade 100 chain and grade 120 chain. Give our sales team a call at 800-969-6543 for more information and to place an order.
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.

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
For example a sling with designation (model) SOG has a single leg (Letter S), with an Oblong Master Link (Letter O) and a Grab Hook (Letter G).
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
Our lifting chain slings are manufactured with Made in the USA chain and European-made fittings for quality you can count. 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.
Proof testing has been done on every link of chain to 2.5 times 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.
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.
