What is the main advantage of G100 chain slings over G80 chain slings?

Grade 100 chain slings provide approximately 25% higher Working Load Limit (WLL) compared to Grade 80 chain slings of the same chain size, allowing users to select a smaller and lighter chain for equal lifting capacity.

How does lifting angle affect the Working Load Limit (WLL) of multi-leg chain slings?

As the angle between the sling legs increases (e.g., from 0°-45° to 45°-60°), the tension on each leg increases significantly, reducing the total allowable WLL according to EN 818-4 standards.

G80&G100 Alloy Steel Chain Slings (1-4 Leg) | Tie Shou

Tie Shou G80 and G100 alloy steel chain slings are engineered for heavy-duty overhead lifting operations under demanding industrial environments. Fully compliant with international rigging standards EN 818-4 and ASME B30.9, our chain sling assemblies are available in Single Leg, 2-Leg, 3-Leg, and 4-Leg configurations with high-strength master links, clevis grab hooks, and self-locking hooks. Capacities range from 1.12 Tons to over 85 Tons with a strict 4:1 Design Factor / Safety Factor.

Engineering Highlights & Grade Comparisons:

Grade 80 (G80) Premium Alloy: Manufactured from quenched and tempered 20Mn2 alloy steel, offering rugged durability, high toughness, and exceptional fatigue resistance for routine industrial rigging.
Grade 100 (G100) Ultra-High Strength: Delivers approximately 25% higher Working Load Limit (WLL) compared to G80 at the same chain diameter, reducing overall sling weight for easier operator handling.
Versatile End Fittings: Custom-assembled with clevis sling hooks, shortening grab hooks, eye foundry hooks, and connecting links based on your specific lifting requirements.
Proof Tested & Tagged: 100% factory proof-tested at 2.5 times WLL and supplied with durable metal ID tags showing rated capacity, chain size, and serial numbers.
