Whether you need a standard lifting sling or a fully customized solution, we can provide a reliable chain sling designed to maximize safety and productivity.
What Is a 2 Leg Chain Sling?
A 2 leg chain sling consists of two alloy steel chain legs connected to a master link at the top and equipped with hooks or specialized end fittings at the bottom.
The dual-leg configuration allows the load to be lifted from two attachment points, providing:
- Improved load stability
- Better weight distribution
- Reduced load swing
- Increased lifting capacity
- Enhanced safety during lifting operations
Compared with single-leg slings, double-leg chain slings are ideal for lifting wide, long, or irregularly shaped loads.
Components of a 2 Leg Chain Sling
A typical 2 leg chain sling includes:
Master Link
The top connecting component attached directly to the crane hook.
Connecting Links
Used to connect the master link to individual chain legs.
Grade 100 Alloy Chain
Manufactured from premium alloy steel for maximum strength and wear resistance.
Sling Hooks
Available options include:
- Self-locking hooks
- Sling hooks
- Grab hooks
- Foundry hooks
- Clevis hooks
Shortening Clutches (Optional)
Allow users to adjust chain length and accommodate uneven loads.
Why Choose Grade 100 Alloy Chain?
Our Grade 100 chain slings provide approximately 25% higher lifting capacity than Grade 80 chain slings of the same diameter.
Benefits of Grade 100 Chain
- Higher Working Load Limit (WLL)
- Excellent fatigue resistance
- Superior abrasion resistance
- Longer service life
- Reduced sling weight
- Enhanced safety margin
2 Leg Chain Sling Capacity Chart
The Working Load Limit depends on chain diameter, sling angle, and lifting configuration.
Grade 100 Two Leg Chain Sling WLL
| Chain Size | WLL at 45°-60° |
| 6 mm | 2.0 Ton |
| 8 mm | 3.55 Ton |
| 10 mm | 5.6 Ton |
| 13 mm | 9.5 Ton |
| 16 mm | 14 Ton |
| 20 mm | 21.2 Ton |
| 22 mm | 26.5 Ton |
| 26 mm | 37.5 Ton |
Capacities may vary according to local standards and fitting configurations.
How Sling Angles Affect Capacity
The angle between sling legs has a significant impact on lifting capacity.
Recommended Sling Angles
- 60° Included Angle – Ideal lifting configuration
- 45° Included Angle – Common industrial use
- Below 30° – Not recommended
As sling angles decrease, tension in each chain leg increases dramatically.
Always follow the rated load chart supplied with the sling.

FAQs About 2 leg chain sling
A 2 leg chain sling is designed for lifting loads from two attachment points. It provides better load balance, improved stability, and increased lifting capacity compared to a single-leg chain sling.
The capacity depends on the chain grade, chain size, sling angle, and load distribution. Always refer to the manufacturer's Working Load Limit (WLL) chart and never exceed the rated capacity.
As the angle between the sling legs decreases, the tension in each leg increases. Smaller sling angles reduce the safe lifting capacity and can create excessive stress on the sling and lifting points.
Grade 100 chain slings offer approximately 25% higher lifting capacity than Grade 80 chain slings of the same diameter. They provide greater strength while maintaining a similar weight.
Yes. A 2 leg chain sling can be used for uneven loads when properly configured. Shortening clutches or adjustable legs can help balance the load. However, the load distribution should be evaluated by a qualified lifting professional.
2 leg chain slings are widely used in construction, oil and gas, mining, marine, shipbuilding, steel fabrication, manufacturing, and heavy equipment maintenance.
Chain slings should be visually inspected before every use. Periodic inspections should be performed by a qualified person according to OSHA, ASME, local regulations, and company safety procedures.
Inspect for cracked links, bent hooks, excessive wear, elongation, corrosion, damaged fittings, missing identification tags, and any signs of deformation.
Yes. Custom options include chain size, sling length, hook type, master link configuration, shortening clutches, surface finish, and OEM markings.
Most Grade 100 chain slings are manufactured with a 4:1 design safety factor and are proof tested according to applicable industry standards.
