5/16" x 10 ft Type ADOSL Adjustable 2-Leg Grade 100 Chain Sling - 9900 lbs WLL

ADOSL Grade 100 Chain Sling – Adjustable Double Leg with Master Link & Self-Locking Hooks

The ADOSL 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 self-closing safety (locking) hooks on each lifting leg, along with two short adjustment legs equipped with grab hooks to fine-tune the effective length of each 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 and high-capacity lifting applications.

• Made from Grade 100 alloy chain and fittings – new and certified
• Double-leg ADOSL configuration with oblong master link
• Self-closing locking hooks on each lifting leg for maximum load retention
• Short adjustment legs with grab hooks for precise length control
• Ideal for two-point lifting and improved load stability
• Individually serialized and furnished with metal load tag
• Load tag indicates chain size, sling length, Working Load Limit, and serial number
• Designed for demanding industrial, construction, and critical lift environments

Why Choose ADOSL Adjustable Chain Slings?

The ADOSL configuration combines the added security of self-locking safety hooks with built-in adjustability. The locking hooks provide positive engagement under load, while the adjustment legs allow operators to shorten or balance sling legs for uneven or offset loads — making this sling ideal for complex lifting scenarios requiring both stability and safety.

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

Understanding Sling Angle & Capacity

Working Load Limits are based on a 60° sling angle. As the sling angle decreases (becomes flatter toward horizontal), tension in each leg increases significantly and the allowable Working Load Limit is reduced. Always account for angle reductions and follow proper rigging charts and lifting standards.

Typical Applications

• Structural steel erection
• Heavy equipment and machinery lifting
• Precast concrete handling
• Industrial shutdown and maintenance work
• Critical lifts requiring enhanced hook security

Frequently Asked Questions

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

When should I choose locking hooks?
Self-locking hooks are ideal for overhead lifts where positive load retention and reduced risk of accidental disengagement are critical.

How does sling angle affect capacity?
Working Load Limits are rated at 60° or less. As sling angles decrease below 60°, tension on each leg increases significantly. Always follow proper rigging angle charts and lifting standards.

Are these slings certified?
Yes. Each ADOSL 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, adjustment legs, and locking hooks before each use.
• Ensure all locking hooks are fully engaged and functioning properly prior to lifting.
• Remove from service if damage, deformation, or overloading is suspected.
