  • LHB Type Explosion-Proof Hoist Double Girder Bridge Crane: Maximum Safety & Power for Hazardous Zones

    LHB Type Explosion-Proof Hoist Double Girder Bridge Crane: Maximum Safety & Power for Hazardous Zones

    When demanding lifting capacity, extended span requirements, and uncompromising safety in explosive atmospheres converge, the LHB Type Explosion-Proof Hoist Double Girder Bridge Crane emerges as the engineered solution. This robust crane integrates the structural strength of a double girder design with intrinsically safe explosion-proof (Ex) components throughout, enabling reliable and compliant heavy lifting in Zone 1/21 and Zone 2/22 hazardous environments found in petrochemical plants, pharmaceutical facilities, grain processing, paint shops, and chemical storage.

    Core Advantages: Power Meets Intrinsic Safety

    1. Superior Load Capacity & Span: The double girder construction provides exceptional rigidity and strength, enabling capacities typically from 5 tons to 100+ tons and spans exceeding 35 meters – capabilities often beyond the reach of single girder explosion-proof cranes.

    2. Comprehensive Explosion Protection: Every component posing an ignition risk – hoist motor, travel motors, control panels, limit switches, pendant stations, wiring systems – is housed within certified Ex d (flameproof), Ex e (increased safety), or Ex i (intrinsic safety) enclosures, preventing sparks or hot surfaces from igniting surrounding flammable gases, vapors, or dusts.

    3. Enhanced Stability & Precision: The double girder design offers superior hook height (maximizing usable lift under the crane) and load stability during travel, crucial for precise placement of heavy or sensitive loads in critical areas. Optional frequency-controlled drives (VF) ensure smooth, jerk-free starts and stops.

    4. Robust Duty Cycle (A5-A7): Built for heavy and very heavy-duty applications common in industries like bulk handling (with grabs) or production lines, far exceeding the typical duty of single girder explosion-proof models.

    5. Flexible Control & Monitoring: Operators use certified Ex d or Ex i pendant controls or explosion-proof radio remote systems. Integration of load moment indicators (LMI) and anti-collision systems is standard for enhanced safety.

    2. Dual Braking Systems: Primary (electromechanical) + secondary (mechanical or regenerative) braking on hoist and critical motions.

    3. Redundant Limit Switches: Upper/Lower hoist limits, trolley/bridge end limits (multiple sets).

    4. Emergency Stop Circuits: Hard-wired E-Stop buttons on pendant/remote, accessible on crane.

    5. Anti-Sway System (Optional): Essential for precise load control, especially with long lifts.

    6. Compliance: Adheres to stringent international and national standards:

      • ATEX Directive 2014/34/EU (EU): Essential for European market.

      • IECEx System (International): Globally recognized certification.

      • GB3836 Series Standards (China): Core standard for Ex equipment.

      • NEC / CEC (North America – Class I Div 1/2, Class II Div 1/2): Requires specific UL/FM approvals.

      • FEM 1.001 / ISO 8306: Structural design standards.

    Installation, Maintenance & Lifecycle Considerations

    • Expert Installation: Requires specialized technicians familiar with Ex equipment installation standards (e.g., IEC/EN 60079-14). Correct earthing/bonding is critical.

    • Strict Inspection Regime: Daily operator checks, frequent inspections by qualified Ex personnel, thorough periodic inspections per regulations (e.g., annually). Focus on integrity of Ex enclosures, cable glands, and seals.

    • Ex-Specific Maintenance: Only certified Ex repair facilities using OEM-approved Ex components can perform repairs to maintain certification. Detailed records are mandatory.

    • Operator Training: Comprehensive training on safe operation in hazardous areas, understanding zone classifications, emergency procedures, and specific hazards of the crane/load.

    • Lifecycle Management: Factor in the higher initial cost and specialized maintenance requirements against the critical safety benefits and operational necessity in hazardous environments.
