Explosion-proof Electric Wir Rope Lifting Crane Introduction

The crane's critical components are built with explosion-proof principles:

Lifting Mechanism: The core lifting unit is an explosion-proof electric hoist (such as HB, BCD, or HBS models), which serves as the primary lifting mechanism .

Electrical Systems: All electrical components, including motors, control stations, and electrical cabinets, feature explosion-proof designs. This may include flameproof enclosures, enhanced sealing (with protection grades up to IP54/IP66), and spark-proof treatments for mechanical parts to prevent the generation of incendive sparks or excessive surface temperatures .

Structural Configurations: They are mainly available in two bridge structures:

Explosion-Proof Single Girder Crane (LB type): Characterized by a compact structure, light weight, and cost-effectiveness, suitable for light to moderate work cycles .

Explosion-Proof Double Girder Crane (QB type): Offers higher lifting capacity and better stability, often used for heavier duties

The Explosion-proof Electric Lifting Crane Applications and Industries

These cranes are indispensable in industries where explosive atmospheres are a risk. Key application areas include:

Petrochemical: Refineries, chemical plants, and gas stations handling volatile substances like petroleum, natural gas, and chemicals .

Mining: Particularly in coal mines where combustible gases like methane may be present .

Military and Aviation: For handling fuels, ammunition, and other hazardous materials .

Other Industries: Also used in warehouses, workshops, and hydropower stations within hazardous zones

Safety and Maintenance

Rigorous safety features and regular maintenance are crucial:

Safety Devices: Standard equipment includes overload protection, travel limit switches, emergency stop switches, anti-falling protection for motors, and audible/visual alarms .

Maintenance Regime: Regular maintenance is vital. This includes checking and replenishing gearbox oil (initially after 500 hours, then every three months), ensuring components are clean and dry, and lubricating the chain regularly, especially in dusty environments .

Explosion-proof electric cranes are highly specialized equipment that ensures operational safety in volatile environments through robust design, adherence to strict standards, and comprehensive safety systems. When selecting a crane, it is essential to match its explosion-proof grade (like ExdⅡBT4) precisely to the specific hazardous substances present in the intended work area
