Custom lifting chain slings are essential for demanding lifting applications that require tailored configurations, special load angles, unique working lengths, or specific end fittings.
At TOPONE CHAIN, we design and manufacture fully customized lifting chain slings using premium G80 and G100 alloy steel, ensuring maximum durability, traceability, and safety for industrial operations worldwide.
With 9 automated production lines, advanced heat-treatment systems, and ISO-certified quality control, TOPONE CHAIN is recognized as a global top-ten lifting chain manufacturer, trusted across construction, shipbuilding, mining, transportation, and heavy machinery sectors.
Custom lifting chain slings are engineered-to-order lifting assemblies built according to your exact specifications:
Number of legs
Working load limit (WLL)
Chain grade and diameter
Lifting angles & load geometry
Type of hooks or end fittings
Adjustability requirements
Coating & corrosion protection
Certification and inspection needs
They offer unmatched flexibility and reliability for jobs where standard slings cannot safely meet the lifting requirements.
Single-leg
2-leg
3-leg
4-leg (most common for complex or heavy loads)
Adjustable or fixed-length configurations
G80 Alloy Steel
G100 Alloy Steel
Optional: Stainless, galvanized, or special-coated versions
Latching hooks
Self-locking hooks
Foundry hooks
Grab hooks
Eye hooks
Shackles
Master links
Custom-engineered fittings
For adjustable-length, multi-angle lifting.
Every sling is tailored to your specific lifting scenario — no over-engineering, no under-capacity risks.
Manufactured from quenched and tempered alloy steel compliant with EN 818-4 and ASME B30.9.
Each sling comes with:
Serial number
Heat-treatment record
Proof-load test certificate
Ideal for complex or multi-point lifting at 0°–90°.
Resistant to wear, impact, and harsh environments.
Custom lifting chain slings are used where precision lifting is critical:
Steel structure installation
Offshore & marine lifting
Heavy equipment positioning
Construction materials handling
Mining & quarry operations
Factory and warehouse logistics
Transportation and rigging systems
Modular building and precast lifting
Shipyard fabrication
