G80 Chain Sling
1. Product Overview
The G80 chain sling is a premium lifting solution engineered for heavy-duty industrial applications. Manufactured from high-grade alloy steel, Grade 80 chain slings offer exceptional strength-to-weight ratios, making them indispensable for safe and efficient load handling in demanding environments. These slings are heat-treated and quenched for superior durability, corrosion resistance, and fatigue life, ensuring compliance with international standards such as EN 818-4, ASME B30.9, and ISO 3076.
Available in various configurations—including single-leg, double-leg, triple-leg, and quadruple-leg assemblies—our G80 chain slings are customizable to meet specific load requirements. Each sling features oblong links, clevis hooks, and master links designed for secure, non-slip connections. With working load limits (WLL) ranging from 0.63 tons to over 20 tons depending on the leg configuration and chain diameter, the G80 chain sling excels in scenarios where precision, reliability, and safety are paramount.
Ideal for international trade and B2B procurement, these slings undergo rigorous testing, including proof load tests at 1.5 to 2.5 times the WLL and magnetic particle inspections for crack detection. This guarantees that every G80 chain sling delivered meets or exceeds global safety regulations, providing peace of mind for rigging professionals worldwide.
2. Key Features
- Grade 80 Alloy Steel Construction: Provides a minimum breaking strength of 800 MPa, four times the working load limit for unmatched safety margins.
- Heat Treatment Process: Quenched and tempered links ensure uniform hardness and elongation, reducing wear and extending service life.
- Corrosion-Resistant Finish: Black oxide or galvanized coating protects against harsh environments, including marine and chemical exposure.
- Interchangeable Components: Standardized fittings like G80 clevis grab hooks, self-locking hooks, and coupling links allow easy assembly and maintenance.
- Identification Markings: Each chain link is embossed with grade, diameter, and manufacturer code for traceability and inspection compliance.
- Custom Lengths: Available from 1m to 10m or longer, with swaged shortening hooks for adjustable rigging.
- Lightweight Design: Despite high capacity, G80 chain slings are up to 20% lighter than lower-grade alternatives, improving handler efficiency.
- Shock Load Resistance: Engineered to absorb dynamic forces without deformation, ideal for overhead cranes and hoists.
These features position the G80 chain sling as the go-to choice for professionals seeking reliability without compromise.

7. FAQ
What is the difference between G80 and G70 chain slings?
G80 chain slings offer higher tensile strength (800 MPa vs. 700 MPa) and better fatigue resistance, making them suitable for overhead lifting, while G70 is typically for transport securement.
Can G80 chain slings be used in choker hitch?
Yes, with a capacity reduction to 80% of WLL. Ensure proper D/d ratio (>1:1) to prevent chain damage.
How do I inspect a G80 chain sling?
Perform daily visual checks for nicks, gouges, or stretch (no more than 5% elongation). Annual professional exams recommended per ASME B30.9.
What is the maximum temperature for G80 chain slings?
Up to 200°C with full WLL; derate by 25% at 300°C and 50% at 400°C.
Are custom G80 chain sling assemblies available?
Absolutely. Specify chain size, leg count, length, and end fittings for tailored solutions.
Do you provide certifications with each G80 chain sling?
Yes, every sling ships with a test certificate, including proof load and inspection results.
