Extra Long Link Mining Chain | High Strength Conveyor Chain for Mining
Our Extra Long Link Mining Chain is purpose-built for harsh mining environments, serving as a critical load-bearing and transmission component for bulk material transportation. Featuring an optimized extra-long link design, it reduces joint friction, minimizes material jamming, and ensures stable operation over long-distance working faces—ideal for high-efficiency mining projects requiring durable and reliable conveyor solutions.
| Parameter | Standard Range | Application Note |
|---|---|---|
| Link Diameter | 10mm – 42mm (Customizable) | Larger diameter = higher load capacity (10–24mm for medium-duty; 30–42mm for heavy-duty) |
| Extra Long Link Length | 50mm – 152mm | Reduces joints; ideal for 450m+ long mining faces |
| Material | High-Strength Alloy Steel (20Mn2/30Mn2/40Cr) | 40Cr for high-corrosion/wear-resistant scenarios |
| Heat Treatment | Quenching + Tempering | Hardness: HRC 40–50; Tensile Strength ≥1000MPa |
| Surface Treatment | Hot-Dip Galvanizing / Baking Paint / Dacromet | Prevents rust in humid/dusty underground conditions |
| Breakage Load | Up to 1100kN (Max) | Safety factor ≥ 2 (twice the working load) |
| Chain Length | 5m – 50m (Custom Rolls) | Matches conveyor/tunneling machine installation needs |
| Compatibility | JCB, CAT, Doosan Standard Sprockets | Seamless integration with mainstream mining equipment |
Core Advantages
Ultra-Durable: Precision-forged links with heat treatment deliver exceptional wear, impact, and corrosion resistance, extending service life and reducing replacement frequency.
High Efficiency: Extra-long link design minimizes friction and material buildup, boosting transportation efficiency for large-scale mining operations.
Safety Certified: Complies with ISO 610, DIN 22252, and South Africa Standards. Equipped with MA (China) and CE (EU) certifications for global market compliance.
✅ Low Maintenance: Rivetless optional structure simplifies assembly; corrosion-resistant coating reduces downtime and labor costs.
Common Applications
Designed for underground/surface mining projects—including coal, ore, and mineral transportation.
Perfect for scraper conveyors, coal ploughs, and tunneling machines in both small-scale and large-scale mining sites.
