What Is a Chain Sling?
A chain sling is a lifting assembly made from high-strength alloy steel chain and suitable lifting components such as master links, hooks, connecting links, and other fittings. It is used to connect a load to a crane, hoist, or other lifting equipment.
Depending on the application, chain slings can be supplied as single-leg, double-leg, triple-leg, or four-leg configurations.
The appropriate sling configuration depends on factors such as:
- Load weight
- Load shape and dimensions
- Centre of gravity
- Lifting angle
- Working Load Limit (WLL)
- Chain grade and diameter
- Type of hooks and fittings
- Lifting environment
Selecting the correct chain sling is important because the rated capacity of a sling can change depending on how it is configured and used.

SVIBO Industries serves industrial requirements as a Chain Sling Manufacturer and Supplier in Pune, offering chain sling solutions for various lifting applications.
The right chain sling should not be selected only based on chain diameter or price. Factors such as grade, configuration, lifting angle, hook type, WLL, and application conditions should also be considered.
Types of Chain Slings
Different lifting operations require different chain sling configurations. Some of the commonly used types include:
1. Single-Leg Chain Sling
A single-leg chain sling consists of one chain leg with suitable end fittings. It is useful when a straightforward vertical lifting arrangement is required.
Common applications include:
- Machinery lifting
- Material handling
- Workshop lifting
- Fabrication work
- General industrial applications
The rated capacity must always be checked before lifting.
2. Double-Leg Chain Sling
A double-leg chain sling uses two chain legs connected to a master link or suitable top fitting. It provides greater flexibility when supporting loads at two lifting points.
It is commonly used for:
- Machinery
- Steel structures
- Industrial components
- Fabricated equipment
- Heavy material handling
The lifting angle has a significant effect on the capacity of multi-leg slings.
3. Three-Leg Chain Sling
Three-leg chain slings are designed for loads requiring three lifting points. They can provide better load distribution when appropriately designed and used.
They are suitable for certain:
- Industrial machinery
- Structural components
- Fabricated assemblies
- Heavy equipment
- Engineering applications
A competent person should determine whether the load and lifting arrangement are suitable for a three-leg configuration.
4. Four-Leg Chain Sling
Four-leg chain slings are used for loads with multiple lifting points. They are commonly considered for large and heavy components where a multi-point lifting arrangement is required.
Applications may include:
- Heavy machinery
- Industrial equipment
- Steel structures
- Large fabricated components
- Construction materials
The actual lifting capacity should be determined based on the manufacturer’s rated configuration and applicable lifting conditions.
5. Adjustable Chain Slings
Adjustable chain sling arrangements can be useful when different lifting lengths or attachment positions are required. They offer flexibility for selected industrial applications.
However, adjustment must be carried out according to the manufacturer’s specifications and safe lifting practices.
Understanding Chain Sling Load Capacity
One of the most important factors when selecting a chain sling is its Working Load Limit (WLL).
WLL indicates the maximum load that a lifting assembly is rated to handle under specified conditions. It should not be confused with the breaking load of the chain.
The capacity of a chain sling depends on several factors, including:
- Chain diameter
- Chain grade
- Number of legs
- Sling configuration
- Lifting angle
- Hitch type
- Hook and fitting capacity
- Load distribution
- Condition of the sling
Why Lifting Angle Matters
For multi-leg chain slings, the angle between the sling legs can affect the forces acting on each leg. As the sling angle becomes more horizontal, the tension in each leg increases.
Therefore, simply adding the capacities of individual chain legs is not an appropriate way to determine the total safe lifting capacity.
Always refer to the manufacturer’s rated capacity chart and applicable lifting standards before using a chain sling.
Common Chain Grades
Chain slings are generally manufactured using high-strength alloy steel chains designed for lifting applications.
Common lifting chain grades include:
Grade 80 Chain Slings
Grade 80 chain is widely used for lifting and material-handling applications. It provides a combination of strength, durability, and versatility.
Grade 100 Chain Slings
Grade 100 chain provides higher strength compared with Grade 80 chain for appropriately designed lifting applications. It can allow certain loads to be lifted using a smaller chain size, subject to the manufacturer’s rated capacity.
The selection between Grade 80 and Grade 100 should be based on the required WLL, application, lifting configuration, applicable standards, and manufacturer recommendations.
