1. Unmatched Strength & Load Capacity

• G80 Alloy Steel Construction: High-tensile strength (≥800 MPa) for heavy-duty lifting, ensuring superior durability.

• Four-Leg Design: Evenly distributes load weight, enhancing stability and safety for large or unbalanced loads.

• Working Load Limit (WLL): Available in 1 ton to 50+ ton capacities, with customizable configurations for extreme loads.

• 4:1 Safety Factor: Exceeds industry standards for critical lifting operations.

2. Superior Durability & Wear Resistance

• Heat-Treated & Hardened Links: Resistant to elongation, deformation, and wear, even under frequent use.

• Abrasion & Impact Resistant: Outperforms wire rope and synthetic slings in rugged environments (e.g., steel mills, construction sites).

• Corrosion Protection: Optional hot-dip galvanized, nickel-plated, or epoxy-coated finishes for harsh conditions (marine, chemical, or outdoor use).

3. Enhanced Safety & Stability

• Balanced Load Distribution: Four-leg configuration minimizes swing and tilting, reducing accident risks.

• No Sudden Failure: Unlike synthetic slings, steel chains show visible wear signs before failure, allowing timely replacement.

• High-Temperature Resistance: Can withstand up to 400°C (752°F) without losing strength (ideal for foundries and welding zones).

4. Versatility & Adaptability

• 360° Swiveling Master Links: Allow flexible rigging angles (vertical, choker, or basket hitch) without twisting.

• Compatible with Hooks, Shackles & Lifting Beams: Easily integrates into existing lifting systems.

• Adjustable Chain Lengths: Some models feature adjustable legs for precise load balancing.

5. Low Maintenance & Long Service Life

• Minimal Stretch: Maintains precise load control without elongation over time.

• Easy Inspection: Clear wear indicators (e.g., measurable link stretch) simplify safety checks.

• Cost-Efficient: Longer lifespan than wire rope or synthetic slings, reducing replacement costs.

6. Compliance & Reliability

• Certified to ISO 3077, ASME B30.9, DIN Standards: Ensures global compliance and safety.

• Full Traceability: Material certifications and test reports provided for quality assurance.

Grade 80 Four-Leg Alloy Steel Lifting Chain Sling – Operation Guide

1. Pre-Use Inspection

✅ Check for Damage – Look for cracks, stretched links, or excessive wear (discard if elongation exceeds 5%).
✅ Verify Load Rating – Ensure the Working Load Limit (WLL) matches your lifting requirements.
✅ Inspect Hooks/Shackles – Confirm they are not bent, warped, or corroded.
✅ Lubrication Check – Chains should be lightly lubricated for smooth operation.

2. Proper Rigging Setup

Choose the Correct Hitch –

• Vertical Hitch – Direct lift with all four legs bearing equal load.

• Basket Hitch – Wrap chains around the load for balanced support.

• Choker Hitch – Secure uneven loads but reduce WLL by 20-30%.

Balance the Load – Adjust leg lengths to ensure even weight distribution.
Avoid Sharp Edges – Use edge protectors if lifting materials with abrasive surfaces.

3. Safe Lifting Practices

⚠ Never Exceed WLL – Account for dynamic forces (e.g., sudden movements).
⚠ Avoid Side Pulling – Lift vertically to prevent chain stress.
⚠ Keep Clear of Load – Stand back during hoisting in case of slippage.
⚠ No Twisting/Kinking – Ensure chains are not tangled before lifting.

4. Post-Use Maintenance

Clean Chains – Remove dirt, grime, or chemical residues after use.
Re-Lubricate – Apply oil or grease to minimize wear.
Record Inspections – Log any damage or wear for future reference.

5. Storage Recommendations

➡ Store Indoors – Keep in a dry, cool place to prevent rust.
➡ Hang or Coil Neatly – Avoid tangling or crushing chains.
➡ Protect from Chemicals – Keep away from acids or corrosive substances.

1. Can I use this sling in high-temperature environments?

• Yes! Standard G80 chains handle up to 400°C (752°F). For hotter conditions (e.g., foundries), inquire about heat-resistant coatings or Grade 100 chains.

2. How do I calculate the actual capacity when using a choker hitch?

• Reduce WLL by 20-30% in choker mode due to uneven stress. Example:

• 10-ton sling → 7-8 tons max in choker configuration.

3. How often should I inspect the chain sling?

• Before every use (quick visual check).

• Formal inspection every 6-12 months (or as per OSHA/ASME standards).

• Immediately after overload or impact.

4. Can I repair a damaged chain link?

• No! Never weld, bend back, or modify damaged links. Replace the entire sling if any component fails inspection.
