INTRODUCTION
What is this?
The LB type explosion-proof electric single girder crane is a cost-effective overhead lifting solution designed for safe operation in hazardous environments. It features a single main beam structure with an explosion-proof electric hoist (CD/MD type with Ex certification). All electrical components including hoist motors, controllers, limit switches, control pendants, and junction boxes are enclosed in certified explosion-proof enclosures, preventing any sparks or high temperatures from igniting explosive gases or dust. If your facility requires light to medium lifting capacity up to 20 tons in classified hazardous zones with limited budget or building space, this product is designed for you.
Why choose an explosion-proof single girder crane over an explosion-proof double girder crane?
Compared to explosion-proof double girder cranes, the LB explosion-proof single girder solution offers four core advantages:
First, lower investment cost – simplified single beam structure reduces manufacturing cost by 30%-40%, making explosion-proof lifting more accessible for budget-limited projects.
Second, faster installation – lighter self-weight with simpler rail requirements, installation and commissioning completed within 7-10 days.
Third, greater headroom – the single girder with bottom-running hoist occupies less overhead space, providing higher effective lifting height under the same building clearance.
Fourth, easier maintenance – fewer components, fewer failure points, and modular explosion-proof hoist design result in lower daily maintenance costs.
Get certified explosion-proof lifting with a more economical single girder structure.
What can we do for you?
We understand that every customer has different hazardous zone classifications, different building structures, and different capacity requirements. Therefore, we offer flexible customization options: explosion-proof levels from Ex d IIB T4 to Ex d IIC T4; temperature classes T1 to T6; capacity from 1 ton to 20 tons; span from 7.5 meters to 22.5 meters; hoist types of CD explosion-proof hoist (single speed) or MD explosion-proof hoist (dual speed); control options of explosion-proof pendant, explosion-proof remote radio, or cabin with purge system; VVVF speed control optional. Whether your hazardous area contains gasoline vapors, hydrogen gas, or combustible dust, we can match the appropriate explosion-proof rating for your specific zone.
Unsure? Don't know?
Not sure what explosion-proof level your facility requires? Not sure whether a single girder crane can handle your capacity needs? No problem. Just tell us: your hazardous zone classification (Zone 1, Zone 2, Zone 21, Zone 22), your building clearance height, and your required lifting capacity. Our engineers will provide you with an accurate quote and CAD 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 explosion-proof requirements, feel free to describe your hazardous environment and handling needs, and we will calculate for you.
