The LDOB Explosion-Proof Single Girder Overhead Crane is a specialized lifting solution designed for hazardous environments where flammable gases, vapors, or dust pose explosion risks. It incorporates anti-spark and flame-resistant components to ensure safe operation in industries such as oil refineries, chemical plants, mining, and gas stations.
Explosion-Proof Design:
Electrical Components: Motors, controls, and wiring are rated ExdⅡBT4 or ExdⅡCT4, preventing sparks or arcs from igniting explosive atmospheres.
Anti-Spark Materials: Stainless steel or nylon wheels and spark-proof coatings on metal surfaces minimize friction-induced sparks.
Lifting Capacity & Performance:
Capacity: 1–10 tons (common range: 1–10 tons).
Span: 7.5–28.5 meters (extendable to 50 meters in custom models).
Lifting Speed: Dual-speed options (e.g., 0.8/8 m/min) for precision tasks.
Safety Mechanisms:
Overload protection, height/travel limit switches, and emergency stops.
PLC-controlled variable frequency drives (VFDs) for smooth acceleration and braking.
Environmental Adaptability:
Temperature Range: Operates in -20°C to +40°C.
Hazardous Zones: Suitable for Zone 1 & 2 (explosive gas/dust environments).

Oil & Gas: Handling materials in refineries, gas stations, and petrochemical plants.
Chemical Facilities: Transporting volatile substances in explosive atmospheres.
Mining & Quarries: Operating in dust-laden environments with flammable particles.
Wastewater Treatment: Safe lifting in methane-rich areas.
Military & Pharmaceutical: Managing explosive or solvent-heavy materials.
ATEX/IECEx Compliance: Meets EU and international standards for explosive environments.
OSHA & ASME: Adheres to workplace safety and mechanical engineering guidelines.
Explosion-Proof Grades:
ExdⅡBT4: For gas/dust groups IIB and temperature class T4.
ExdⅡCT4: Higher protection for gas/dust groups IIC (e.g., hydrogen, acetylene).
Risk Mitigation: Eliminates ignition sources through sealed motors and non-sparking components.
Operational Efficiency: Dual-speed hoists and VFDs enable precise load handling.
Durability: Corrosion-resistant materials (e.g., stainless steel) extend lifespan in harsh conditions.
Cost Savings: Reduces downtime and accident-related losses in hazardous zones.
The LDOB Explosion-Proof Single Girder Overhead Crane is essential for industries requiring safe material handling in volatile environments. Its compliance with international safety standards and adaptability to diverse applications make it a critical asset for mitigating explosion risks while maintaining operational efficiency.
