FAQ
Q: Which hazardous gases are compatible with this explosion-proof crane?
A: The crane is certified for ExdⅡBT4 gases (ethane, propane, gasoline, acetone, benzene, methanol, toluene, vinyl chloride, etc.) and ExdⅡCT4 gases (hydrogen, water gas, acetylene), covering most industrial explosive atmospheres with ignition temperatures not lower than T4 (135°C).
Q: What makes the “C” type structure design advantageous for explosion-proof applications?
A: The classic “C” type structure with spatial rod support provides optimal load distribution, minimizes working blind areas, and ensures safe operation in explosive atmospheres while maximizing workspace utilization and reducing structural complexity.
Q: How does the maintenance-free design benefit explosion-proof operations?
A: The maintenance-free design reduces the need for frequent servicing in hazardous areas, minimizing personnel exposure to explosive atmospheres while ensuring continuous reliable operation through pre-filled reducers, maintenance-free components, and automatic systems.
Q: What intelligent monitoring capabilities are available for explosion-proof environments?
A: The crane features comprehensive security monitoring, big data management with cloud platform connectivity, and real-time mobile APP monitoring, enabling remote oversight while maintaining explosion-proof safety standards.
Q: How does the modular design enhance flexibility in explosion-proof applications?
A: The modular design allows the same hoisting devices to be configured in four different structural modes (standard headroom, low headroom, crab running, and fixed type), providing optimal solutions for diverse explosion-proof facility requirements.
