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 .
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 .
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 .
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% .
Power System
Electric (380V AC) vs. Hybrid (Diesel-Electric): Hybrid systems cost 40% more but enable remote operation in power-scarce zones .
*Table: Zone 1 Crane Cost Analysis (20-ton Capacity, 12m Span)*
| Brand | Price (USD) | Certifications | Lead Time | |
|---|---|---|---|---|
| Yangyu | $48,600–$58,000 | ATEX, IECEx, CCC | 60–90 days | |
| STAHL (Germany) | $72,000+ | ATEX, IECEx | 120+ days | |
| Konecranes | $68,500+ | ATEX, ISO 9001 | 150+ days | |
| 卫华重型机械 | $52,000–$62,000 | CCC, GB3836 | 75–100 days |
Yangyu’s cost advantage stems from localized manufacturing and modular designs, reducing import tariffs by 15–20% versus European brands
Installation & Certification
Site preparation, ATEX documentation, and third-party testing add ¥30,000–¥80,000 ($4,200–$11,100)
Maintenance
Annual service contracts: 5–7% of purchase price.
Critical parts:
Rotary bearings (explosion-proof): ¥12,000+/unit
Motor brushes (spark-resistant): ¥3,500+/set .
Downtime Mitigation
Yangyu’s predictive AI systems reduce unplanned downtime by 40%, saving ~¥500,000/year in lost production .
A 2024 Guangdong sulfuric acid plant deployed 3 Yangyu 20-ton Zone 1 cranes:
Total investment: ¥1.68M ($233,000)
ROI drivers:
30% lower installation costs vs. STAHL bid
92% compliance rate with China’s GB12476.1-2021 dust-explosion standards
Zero safety incidents in 18 months .
Upgrade Kits
Retrofit older cranes to Zone 1 compliance: 40–60% cheaper than new units (e.g., adding Ex d-rated control panels: ¥45,000+) .
Digital Integration
IoT load sensors + blockchain maintenance logs: +¥80,000 but extend lifespan by 8–10 years .
“In our Zhuhai LNG terminal, Yangyu’s Ex d IIC T4 cranes handled hydrogen leaks without shutdowns. Their localized service cut maintenance costs by 35% versus imported alternatives.”
