Tag: Explosion-proof cranes

Zone 1 explosion-proof cranes are engineered for environments where flammable gases, vapors, or dusts are likely to exist during normal operations (e.g., petrochemical plants, refineries). Unlike standard cranes, these integrate intrinsically safe components, flameproof enclosures (Ex d), and spark-resistant materials to prevent ignition. Yangyu’s Zone 1 cranes exceed ATEX/IECEx standards, targeting high-risk areas with classifications like Ex d IIC T4 for hydrogen-rich environments .

Key Cost Drivers for Yangyu Zone 1 Cranes

1. Lifting Capacity & Span

   • Costs scale dramatically with capacity:

     • 5-ton models: ~¥90,000–¥150,000 ($12,500–$20,800)

     • 20-ton models: ~¥350,000–¥550,000 ($48,600–$76,400) 

   • Span increases directly impact steel tonnage and structural complexity. A 16.5m span adds 15–20% to base costs versus a 7.5m span .

2. Explosion-Proof Certification Level

   • Ex d IIB T4: Standard gas protection (e.g., propane, benzene) – baseline pricing.

   • Ex d IIC T4: Enhanced protection for hydrogen/acetylene – 25–30% premium due to reinforced enclosures and specialized wiring .

3. Duty Cycle & Duty Class

   • A3 (Medium Duty): Standard for warehouses – lowest cost tier.

   • A5 (Heavy Duty): For continuous operation in foundries – requires hardened gears and motors, adding 20–25% .

4. Power System

   • Electric (380V AC) vs. Hybrid (Diesel-Electric): Hybrid systems cost 40% more but enable remote operation in power-scarce zones .

Price Comparison: Yangyu vs. Global Competitors
