Description
Our Quadruple Leg (4-Leg) Grade 80 (G80) Alloy Steel Chain Slings are engineered for professional heavy-duty lifting applications where supreme balance, load distribution, and stability are critical. Manufactured from high-tenacity alloy steel and fully compliant with EN 818-4 standards, these multi-leg slings provide a robust solution for complex overhead lifting, construction rigging, and heavy industrial engineering.
Every assembly is custom-built to your exact site requirements in the UK, including adjustable reach configurations and a comprehensive choice of specialized terminal fittings to suit your specific lift.
Key Features:
-
Heavy-Duty G80 Steel: Constructed from premium Grade 80 heat-treated alloy steel for a superior strength-to-weight ratio, maximum abrasion resistance, and long-term industrial durability.
-
Fully Certified: Assembled to order and supplied with a mandatory metal ID tag featuring a unique serial number, Working Load Limit (WLL), and a Certificate of Conformity for full site compliance.
-
Custom Configurations: Available in chain diameters from 7mm up to 16mm and effective working lengths up to 10 Metres to cover standard and heavy-capacity spans.
-
Optional Shorteners: Choose to include integrated shortening clutches to allow for precise manual adjustment of all four leg lengths—essential for keeping unbalanced or irregular loads completely level.
-
Safety Factor: 4:1 safety ratio in strict accordance with international lifting safety standards.
