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 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. 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. 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. Robust Duty Cycle (A5-A7): Built for heavy...
