Grade 80 SSG Chain Sling is a single-leg lifting assembly manufactured from quenched and tempered Grade 80 alloy steel chain and components. The sling is fitted with a Grade 80 sling hook with safety latch on the top and a Grade 80 grab hook on the bottom, making it suitable for lifting applications requiring secure load engagement and adjustable chain length.
The sling hook is equipped with a safety latch to help reduce accidental disengagement during lifting, while the grab hook allows the effective chain length to be shortened by engaging individual chain links without additional shortening devices. This configuration provides greater flexibility when handling loads with different lifting heights or offset lifting points.
S = Single Leg
S = Sling Hook with Latch
G = Grab Hook
SSG therefore refers to a Single Leg Chain Sling fitted with a Sling Hook with Latch on the top and a Grab Hook on the bottom.
Each sling is permanently identified with:
Individual Serial Number
Chain Size
Chain Grade
Exact Sling Length
Working Load Limit (WLL)
The serial number on the identification tag corresponds with the production certificate and sales order record, ensuring complete product traceability throughout the product life cycle.

Design Factor 4:1
The minimum breaking force of the sling assembly is at least 4 times its Working Load Limit (WLL).
90 Degrees
The sling is lifting vertically with no sling angle reduction.
60 Degrees / 45 Degrees / 30 Degrees
The angle between each sling leg and the horizontal plane. As the angle decreases, the sling capacity decreases.
Load Factor
A multiplier used to calculate the Working Load Limit based on the number of sling legs and the lifting angle.
WLL Values (lbs)
The numbers shown in the table represent the maximum Working Load Limit in pounds for each chain diameter and sling configuration.
Example:
For a 1/2" chain sling:
1-Leg Sling = 12,000 lbs
2-Leg Sling at 60° = 20,800 lbs
2-Leg Sling at 45° = 17,000 lbs
2-Leg Sling at 30° = 12,000 lbs
3 & 4-Leg Sling at 60° = 31,200 lbs
3 & 4-Leg Sling at 45° = 25,500 lbs
3 & 4-Leg Sling at 30° = 18,000 lbs
Note: The lifting angle shown in this table is measured from the horizontal. Smaller angles result in higher tension in each sling leg and lower overall lifting capacity.
