Explosion Proof Overhead Crane is a specialized lifting system designed for hazardous environments with flammable gases or dust. Zomax’s models feature flameproof enclosures and insulated components to ensure maximum safety.
With lifting capacities up to 320 tons and customizable single or double girder designs, they offer safe, reliable performance tailored to your specific industrial needs.
Explosion proof cranes operate similarly to conventional overhead cranes but with specialized modifications to prevent ignition in volatile environments:
Flameproof Enclosures (Exd): Motors and electrical components are enclosed in flame-resistant housings to prevent sparks or heat from igniting surrounding gases or dust.
Class H Insulation & IP Ratings: Electrical parts feature Class H insulation and IP65-rated enclosures; motors achieve IP66, offering strong protection against dust and water ingress.
Non-Sparking Components: Innovative mechanical structures minimize friction and eliminate spark risk.
Control Options: Available with pendant control, wireless remote, or cabin operation for safe and ergonomic handling.
Certified Explosion Proof (ATEX, CSA, CCC, IECEx) for both gas and dust environments
Ex-proof Levels: Exd IIBT4 or Exd IICT4, suitable for various hazardous zones
Temperature Resistance: Standard range from -20°C to +40°C
Built-In Limiters & Brakes: Prevents overload and ensures smooth operation
Ergonomic Interface: Easy and intuitive control systems to reduce operator fatigue and improve response time
Maintenance-Friendly Design: Accessible service points for quick inspection and reduced downtime
