Application Scenarios

The versatility of our Link chain makes it indispensable across a wide range of industries. In construction and lifting operations, Link chain forms the backbone of overhead cranes, chain hoists, and rigging slings, handling loads from light-duty tasks to multi-tonne lifts with safety margins exceeding regulatory requirements.

For mining and quarrying, the robust design of Link chain withstands abrasive environments, powering conveyor systems, drag chains, and haulage applications where dust, moisture, and impact are constant challenges.

In maritime and offshore sectors, galvanized or stainless Link chain excels in anchor chains, mooring lines, and towing setups, resisting saltwater corrosion while providing high breaking strengths for vessel stability.

Manufacturing and automation benefit from precision-engineered Link chain in assembly lines, pallet conveyors, and robotic arms, ensuring smooth operation and minimal maintenance. Additionally, in agriculture and forestry, Link chain supports logging grapples, bale handlers, and heavy machinery attachments.

Our Link chain is also widely used in entertainment rigging for stage equipment and in automotive recycling for scrap handling, proving its adaptability in both high-stakes and everyday industrial scenarios.

Advantages

Choosing our Link chain delivers distinct advantages over standard market offerings. First, its superior material composition and advanced manufacturing yield a fatigue resistance up to 20% higher than competitors, reducing replacement frequency and operational costs.

Second, comprehensive testing—including ultimate tensile strength verification and non-destructive crack detection—ensures zero defects, backed by third-party certifications from bodies like SGS and BV.

Third, the ergonomic design of Link chain links facilitates easier slinging and faster installation, boosting productivity without compromising safety. Its high working load limits allow for lighter chain weights in assemblies, optimizing transport and handling.

Furthermore, our commitment to sustainability means eco-friendly production processes with recyclable steel, aligning with global green standards. In summary, this Link chain combines performance, longevity, and compliance for unbeatable value in B2B supply chains.

FAQ

What is the difference between Grade 80 and Grade 100 Link chain?

Grade 80 Link chain offers a minimum breaking strength of 800 N/mm², suitable for general lifting. Grade 100 provides 1000 N/mm² for higher loads, ideal for overhead lifting where maximum strength is critical. Both exceed safety factors of 4:1 for WLL.

Is your Link chain suitable for overhead lifting?

Yes, our Grade 80 and Grade 100 Link chain are explicitly rated for overhead lifting per EN818-2 and ASME B30.9 standards. Always use with compatible hooks, end fittings, and follow load charts.

What surface treatments are available for Link chain?

Standard options include self-colored, electric galvanized (for corrosion resistance), hot-dip galvanized (heavy-duty), and 304/316 stainless steel. Custom phosphating or powder coating available.

How do I determine the correct size of Link chain for my application?

Select based on required WLL, safety factor (typically 4-6:1), and environmental conditions. Consult our technical table or engineers for precise recommendations, ensuring the chain diameter matches your setup.

Do you provide test certificates with Link chain orders?

Absolutely. Each shipment includes a mill test certificate (MTC) detailing chemical composition, mechanical properties, and proof test results, compliant with international standards.

What is the lead time for bulk Link chain orders?

Standard sizes ship within 7-15 days; custom orders in 20-30 days. We maintain large inventories for popular Link chain diameters to meet urgent demands.

Can Link chain be repaired if damaged?

No—damaged Link chain must be discarded. Inspect regularly for wear, cracks, or elongation exceeding 5%. Replacement links are not recommended for load-bearing applications.
