QB Explosion-Proof Overhead Crane
Factory-Direct|ATEX/IECEx-Compliant|Safe Lifting for Hazardous Environments
The QB Explosion-Proof Overhead Crane is engineered for industrial environments where flammable gases,
explosive vapors,combustible dust,or volatile chemicals present operational risks.As a factory-direct manufacturer,
we produce each crane with reinforced steel structures,explosion-proof hoists,flameproof electrical systems,
and precision variable-speed controls to ensure safe,reliable,and stable lifting inside hazardous zones.
Designed for continuous operation in petrochemical plants,paint workshops,gas filling stations,chemical processing lines,
grain warehouses,battery plants,and hazardous material storage,the QB crane integrates explosion-proof technology,
anti-static components,and temperature-controlled motors to meet the rigorous demands of Zone 1 and Zone 2 explosive atmospheres.
Its high structural rigidity,dual-speed lifting system,and advanced spark-prevention design
make it one of the most trusted explosion-proof cranes for manufacturing environments that cannot compromise on safety.
Product Advantages
1.Certified Explosion-Proof Design(ATEX/IECEx/CNEX)
All motors,junction boxes,brakes,limit switches,and control enclosures adopt explosion-proof housings,ensuring sparks or high surface temperatures never come into contact with flammable gases or combustible dust.
2.High-Performance Explosion-Proof Hoist
Sealed motors,copper-alloy anti-spark wheels,precision flameproof brakes,and thermal overload protection ensure smooth lifting of hazardous materials.
3.Stable Control&Anti-Sway Motion
Frequency inverter control guarantees smooth acceleration/deceleration,improved load placement accuracy,and minimal swing,suitable for chemical drums,powders,and flammable liquids.
4.Corrosion,Heat,and Static-Resistant Design
Anti-static coatings,chemical-resistant paint,and humidity-resistant electrical components protect the crane in corrosive atmospheres.
5.Robust Double-Girder Construction
High-strength welded girders minimize deflection and maintain stability during long-span,continuous operations.
