9/32" (1/4") x 10 ft Type ADOS Adjustable 2-Leg Grade 100 Chain Sling - 7400 lbs WLL

ADOS Grade 100 Chain Sling – Adjustable Double Leg with Master Link & Sling Hooks

The ADOS Grade 100 Chain Sling is an adjustable double-leg lifting sling manufactured from premium Grade 100 alloy chain and fittings. This configuration features an oblong master link on one end with latched sling hooks on each lifting leg, along with two short adjustment legs equipped with grab hooks to modify the effective length of each lifting leg.

We offer online purchase sizes from 7/32" through 3/4", with Working Load Limits ranging from 4,700 lbs up to 61,100 lbs (rated at a 60° sling angle). Larger chain diameters and higher capacities are available on a per-quote basis for engineered lifting applications.

Why Choose ADOS Adjustable Chain Slings?

The ADOS configuration combines the stability of a double-leg sling with built-in adjustability. The additional grab hook adjustment legs allow operators to shorten or balance sling legs quickly, making it ideal for uneven load geometries, shifting centers of gravity, or applications requiring precise positioning.

Grade 100 alloy chain delivers approximately 25% higher Working Load Limits compared to Grade 80 chain of the same diameter — providing greater lifting capacity without increasing sling weight.

Understanding Sling Angle & Capacity

Working Load Limits are rated at a 60° sling angle. As the sling angle decreases toward horizontal, tension in each sling leg increases significantly and the allowable Working Load Limit decreases. Always follow proper rigging angle charts and lifting standards.

Typical Applications

• Structural steel erection
• Machinery and equipment lifting
• Precast concrete handling
• Industrial maintenance and shutdown work
• Uneven or offset load lifting

Frequently Asked Questions

What does “ADOS” mean?
ADOS denotes an adjustable double-leg chain sling with sling hooks on each leg and grab-hook adjustment legs for length control.

When should I choose an adjustable sling?
Adjustable slings are ideal when lifting loads with uneven pick points or when precise leg length adjustments are needed for balance.

How does sling angle affect capacity?
Working Load Limits are rated at a 60° sling angle. As the angle decreases toward horizontal, tension in each sling leg increases significantly and the allowable Working Load Limit decreases. Always follow proper rigging angle charts and lifting standards.

Are these slings certified?
Yes. Each ADOS chain sling is furnished with a metal load tag displaying chain size, sling length, Working Load Limit, and a unique serial number for traceability.

Important Safety Information

• Use only by trained and qualified personnel.
• Never exceed the Working Load Limit.
• Observe proper sling angle limitations — Working Load Limits decrease as sling angles become flatter (below 60°).
• Inspect chain, master link, grab hooks, and sling hooks before each use.
• Ensure all hooks are properly engaged prior to lifting.
• Remove from service if damage, deformation, or overloading is suspected.
