4 leg adjustable lifting chains are the most versatile and powerful lifting assemblies for handling heavy, irregular, or multi-point loads. Designed with four adjustable chain legs, these slings allow users to independently control the chain length using built-in shortening clutches, ensuring precise balance and stability during lifting operations.
At TOPONE CHAIN, we manufacture certified G80 and G100 4 leg adjustable lifting chains built for demanding lifting applications in construction, mining, shipbuilding, and heavy machinery industries.

Q1: What’s the difference between adjustable and fixed 4 leg slings?
Adjustable slings allow you to change the chain length for different load sizes or lifting angles, while fixed ones have a set length.
Q2: Can adjustable slings handle uneven loads?
Yes, each leg can be shortened individually to maintain load balance during lifting.
Q3: What’s the maximum load capacity?
Depending on grade and chain diameter, WLL can range from 2 tons up to 21 tons or more.
Q4: Are TOPONE’s 4 leg lifting chains certified?
Yes. All chains are CE / TÜV / ISO certified and come with load test certificates.
The 4 leg adjustable lifting chain is the ultimate solution for heavy, multi-point lifting. With its robust design, adjustable shortening clutches, and certified G80/G100 alloy steel construction, it ensures maximum safety, flexibility, and efficiency across every lifting task.
