INTRODUCTION
What is this?
The LHB type explosion-proof hoist double girder crane is a compact heavy-duty overhead crane designed for safe operation in hazardous environments. It features a double main beam structure with an explosion-proof electric hoist running between or on top of the girders. Unlike traditional wire rope trolley cranes with open motors, all electrical components including hoist motors, controllers, limit switches, and control pendants are enclosed in certified explosion-proof enclosures. If your facility requires medium to heavy lifting capacity up to 32 tons in classified hazardous zones with limited headroom, this product is designed for you.
Why choose an explosion-proof hoist double girder crane over a traditional explosion-proof wire rope trolley crane?
Compared to traditional explosion-proof wire rope trolley cranes, the LHB hoist solution offers four core advantages:
First, more compact design – the integrated explosion-proof hoist occupies less headroom space, providing higher effective lifting height under the same building clearance.
Second, lower self-weight – the hoist-type design reduces overall crane weight by 15%-25% compared to wire rope trolley cranes, lowering building load requirements.
Third, easier maintenance – modular explosion-proof hoist components allow quick replacement and reduce downtime during maintenance.
Fourth, lower investment cost – simplified structure with hoist integration reduces manufacturing cost by 20%-30% while maintaining the same explosion-proof certification.
Get compact explosion-proof lifting with higher efficiency and lower cost.
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 32 tons; span from 7.5 meters to 25.5 meters; control options of explosion-proof pendant, explosion-proof remote radio, or cabin with purge system; VVVF speed control for smooth start/stop. 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 hoist-type or trolley-type crane suits your headroom? 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 building structure, and we will calculate for you.
