The KOEO HHBB is a fully certified explosion proof 2 ton motorized trolley electric chain hoist rated Exd II CT4, delivering both vertical lifting and horizontal powered travel in Zone 1 and Zone 2 hazardous areas. Engineered for petrochemical drum filling lines, paint manufacturing material handling, and chemical warehouse operations, the HBS-2T-Ex features independently certified flameproof lifting and trolley motors with IP65 protection, anti-static G80 alloy steel chain, explosion proof dual-axis pendant control, and copper-free yellow body construction. The integrated explosion proof trolley carriage with flameproof travel motor eliminates manual pushing in hazardous areas, significantly improving both safety and operational efficiency in classified environments.

• Dual Exd II CT4 Motor Certification: Both the 1.5 kW lifting motor and 0.4 kW trolley motor feature independently certified flameproof enclosures rated Exd II CT4 for Zone 1 and 2. Each motor enclosure is tested to prevent internal ignition from propagating into flammable atmospheres.
• Integrated Explosion Proof Trolley System: The powered trolley carriage with hardened stainless steel wheels and flameproof travel motor provides smooth 11 m/min horizontal travel on monorail beams. The trolley frame is copper-free aluminum alloy with yellow visibility coating.
• Anti-Static G80 Chain (Diameter 10.0 mm): Premium 10.0 mm G80 calibrated alloy steel chain with anti-static surface treatment for 2-ton lifting in flammable atmospheres. Precision guides minimize friction during combined lift-and-travel operations.
• Flameproof Dual-Axis Pendant Control: The Exd-certified pendant features separate lift and travel controls with encapsulated switches. 48V intrinsically safe operation on both axes with emergency stop triggering both brake systems simultaneously.
• Independent Explosion Proof Brakes: Separate flameproof DC brakes on the lifting and travel drives provide independent load holding and trolley positioning. Both brakes are fully encapsulated with zero exposed spark-generating surfaces.
• Stainless Steel Trolley Components: Trolley wheels, axles, and adjustment mechanisms are manufactured from spark-proof stainless steel. Sealed PTFE bearings require zero lubrication, eliminating combustible grease contamination in hazardous areas.
• Copper-Free Yellow Construction: Complete hoist and trolley assembly uses copper-free aluminum alloy and stainless steel. High-visibility yellow coating enables rapid identification in hazardous area equipment zones with multiple classified workstations.

The EQFC is certified for petrochemical drum and IBC filling lines with overhead monorail systems, paint and coating manufacturing raw material handling, pharmaceutical solvent warehouse operations, chemical processing intermediate product transfer, and any Zone 1 or Zone 2 classified area where powered horizontal travel improves both safety and throughput compared to manual push trolleys. The complete system certification simplifies hazardous area compliance documentation.

Each EQFC is packed in a KOEO-branded heavy-duty plywood case with anti-static wrapping, reinforced foam padding, and silica gel desiccant packs. Anti-static export-grade outer carton with steel banding. Every unit undergoes 100 percent factory load testing at 1.25 times rated capacity (2.5 tons) with ATEX flameproof integrity verification, spark generation analysis, and trolley traverse testing. CE certified, ATEX 2014/34/EU compliant. ISO 9001:2015 manufactured. G80 chain EN 818-7 certified. Delivery within 15 to 20 working days for stock, 30 to 40 days for production.
