INTRODUCTION
What is this?
The explosion-proof double-girder bridge crane is a double girder bridge crane specifically designed for environments with explosive gases or dust. It features flameproof motors, non-sparking materials, and anti-static design to achieve safe material handling in hazardous areas such as chemical plants, oil refineries, paint workshops, and pharmaceutical factories. If you are managing a production workshop with flammable and explosive risks and need a crane that can safely operate in Zone 1/Zone 2 or Zone 21/Zone 22 areas, this product is designed for you.
Why choose an explosion-proof crane over a standard bridge crane?
Compared to standard bridge cranes, the explosion-proof crane offers four core advantages:
First, explosion-proof certification – the entire crane complies with Ex d IIB T4 or Ex d IIC T4 explosion-proof standards, suitable for gas and dust explosive environments, with third-party certification available.
Second, non-sparking design – all moving parts use non-sparking materials such as copper or beryllium bronze, brakes are explosion-proof non-sparking type, eliminating spark generation.
Third, comprehensive electrical protection – motors are flameproof Ex d or increased safety Ex e, electrical cabinets are pressurized or flameproof type, with IP55 or higher protection rating.
Fourth, anti-static grounding – wire ropes and hook blocks have anti-static grounding function to prevent static accumulation that could cause explosions.
Protect every lift in hazardous environments with professional explosion-proof design.
What can we do for you?
We understand that every customer has different explosion-proof zone requirements, different materials, and different working conditions. Therefore, we offer flexible customization options: lifting capacity from 5 tons to over 100 tons; explosion-proof ratings of Ex d IIB T4, Ex d IIC T4, etc.; temperature classes T4, T5, T6; control options of remote radio or explosion-proof cabin; VVVF speed control optional. Whether your hazardous area is gas or dust environment, we can match the most suitable explosion-proof rating and configuration.
Unsure? Don't know?
Not sure whether your site is Zone 1 or Zone 2? Not sure what explosion-proof rating and temperature class you need? No problem. Just tell us: the name of the flammable substance present (e.g., hydrogen, acetylene, dust, etc.), your explosion-proof zone classification, and your lifting requirements. Our engineers will provide you with an accurate quote and explosion-proof drawings within 24 hours. Click the button below or contact us via WhatsApp/email to get your customized solution.
💡 Tip: We offer free selection consulting. Even if you are unsure about specific parameters, feel free to describe your hazardous environment type and handling needs, and we will recommend the appropriate explosion-proof rating for you.
