The G70 Transport Chain (Grade 70 Chain) is a high-strength chain specifically designed for cargo securement, load binding, and transport applications. It is widely used in trucking, shipping, and heavy hauling due to its durability, strength, and compliance with transportation safety regulations.
Key Features of G70 Transport Chain
1. Material & Strength:
- Made from high-carbon steel, heat-treated for increased strength.
- Grade 70 indicates a minimum tensile strength of 70,000 psi (stronger than Grade 30 or 43 chains).
- Working Load Limit (WLL) is about 1/4 of its break strength (e.g., a 3/8" G70 chain has ~6,600 lbs WLL).
2. Coating & Durability:
- Often galvanized (zinc-coated) for corrosion resistance.
- Some versions have yellow chromate coating (for easy identification and extra rust protection).
3. Links & Design:
- Short-link design (tighter, more compact links than logging chains).
- Embossed markings (e.g., "G70" or "7") to verify grade and authenticity.
4. Compliance & Standards:
- Meets U.S. DOT (Department of Transportation) regulations for cargo securement.
- Complies with WSTDA (Web Sling & Tie Down Association) and OSHA standards.
5. Common Uses of G70 Transport Chain:
- ✔ Flatbed trucking (securing heavy equipment, steel coils, lumber).
- ✔ Shipping containers (lashing containers to ships or railcars).
- ✔ Heavy machinery transport (bulldozers, excavators, etc.).
- ✔ Towing & recovery (used with load binders for extra security).
6. Accessories Used with G70 Chain:
- Lever binders or ratchet binders (for tensioning).
- Grab hooks (slip-resistant hooks for secure attachment).
- Shortening clutches (to adjust chain length).
7. Why Choose G70 Over Regular Chains?
- Legal compliance (required for professional transport).
- Higher safety margin (stronger than Grade 30/43).
- Better durability (resists wear from constant tensioning).
