Explosion-Proof Overhead Crane

Brand: Henan Hengkun Crane Co., Ltd.
Applications: Hazardous environments such as oil refineries, chemical plants, gas storage facilities, pharmaceutical production zones, mining, and other areas with explosive gases, dust, or vapors.

Product Overview

Our explosion-proof overhead crane is engineered for safe operation in flammable or explosive atmospheres, adhering to global safety standards (ATEX, IECEx, NEC). Featuring intrinsically safe components, anti-static design, and spark-resistant materials, it ensures zero ignition risks during lifting operations. Ideal for Zone 1/21 and Zone 2/22 hazardous areas, this crane combines reliability, durability, and compliance to protect both personnel and infrastructure.

Key Technical Advantages

Explosion-Proof Certification
- ATEX/IECEx-certified motors, electrical panels, and control systems.
- Spark-free aluminum alloy trolley wheels and copper alloy tools.
Enhanced Safety Design
- Double sealing (IP66) for motors and junction boxes to prevent gas/dust ingress.
- Grounding systems and anti-static coatings to eliminate electrostatic discharge.
Robust Construction
- Corrosion-resistant steel structure with epoxy coatings (ISO 12944 C4/C5 standards).
- Reinforced braking systems with emergency power backup.
Precision Control
- Explosion-proof variable frequency drives (VFD) for smooth speed regulation.
- Remote control options (radio/wired) to minimize operator exposure to hazardous zones.
