IP65 Quad Motor Explosion Proof Electric Hoist 380V 20 Ton Electric Hoist Exd II

The KOEO EQFC20-08 is the highest capacity explosion proof electric chain hoist in the KOEO lineup, delivering 20 ton lifting with full Exd II CT4 hazardous area certification. Engineered for the most demanding Zone 1 and Zone 2 heavy lifting operations in petrochemical complexes, offshore platform major maintenance, and refinery reactor replacement projects, the EQFC20-08 features a quad explosion proof motor configuration with four synchronized 4.5 kW flameproof IP65 motors (18 kW total), a 4-fall anti-static G80 alloy steel chain system, and quad independent explosion proof DC brakes. Every component from the flameproof motor enclosures to the 48V pendant controller carries individual ATEX certification, with a comprehensive System Integration Declaration covering the complete assembled hoist. The EQFC20-08 represents the ultimate expression of explosion proof lifting engineering for the world's most hazardous heavy industrial environments.

• 20 Ton Exd II CT4 Hazardous Area Certification: The highest certified capacity explosion proof chain hoist available, delivering 20000 kg lifting with complete ATEX flameproof certification for Zone 1 and Zone 2 areas. Each motor, brake, and electrical component carries individual Exd II CT4 certification.
• Quad Explosion Proof Motor System (18 kW): Four synchronized 4.5 kW flameproof IP65 motors provide balanced 18 kW total lifting power with triple redundancy. Electronic load sharing ensures smooth synchronized operation of all four independent drive paths through sealed flameproof junction boxes.
• 4-Fall Anti-Static G80 Chain (Diameter 11.2 mm): Four independent 11.2 mm G80 alloy steel anti-static chain falls distribute the 20-ton load across eight individual load-bearing strands. 4:1 safety factor with complete ATEX material certification and individual chain strand traceability.
• Quad Explosion Proof DC Brake System: Four independent flameproof electromagnetic DC brakes provide the highest level of safety redundancy available in hazardous area lifting. Even with two brakes offline, the remaining system maintains full 20-ton load holding capability.
• Copper-Free Stainless Steel Construction: All load-bearing components including hooks, chain guides, and load sheaves are manufactured from spark-proof stainless steel. External body components use copper-free aluminum alloy with high-visibility yellow ATEX-compliant coating.
• Flameproof Load Synchronization Controller: The central controller continuously monitors and adjusts all four chain paths in real-time through intrinsically safe sensors. The sealed flameproof enclosure maintains Exd II CT4 certification while providing anti-sway load leveling for unbalanced 20-ton components.
• Complete ATEX System Certification Package: Includes individual certificates for all four motors, four brakes, pendant controller, synchronization controller, and limit switches, plus the master System Integration Declaration and full factory hazardous area test documentation for audit compliance.

The EQFC20-08 is certified for petrochemical reactor replacement projects in Zone 1 classified areas, offshore oil and gas platform major equipment overhauls, refinery crude distillation unit maintenance, LNG liquefaction train heavy component handling, chemical plant pressure vessel installation, and any hazardous area application where 20-ton certified explosion proof lifting capability is required. The quad motor and quad brake configuration provides the safety redundancy demanded by major hazard facility risk assessments in the oil and gas industry.

Each EQFC20-08 is packed in a KOEO-branded heavy-duty plywood case with anti-static wrapping, reinforced internal steel frame, high-density polyurethane foam padding, and industrial-grade silica gel desiccant packs. Anti-static export-grade outer carton with heavy-duty steel banding and shock-watch impact indicators. Every unit undergoes 100 percent factory load testing at 1.25 times rated capacity (25 tons) with complete ATEX flameproof integrity verification, quad motor synchronization testing, spark generation analysis, and individual component certification documentation. CE certified, ATEX 2014/34/EU compliant. ISO 9001:2015 manufactured. G80 chain EN 818-7 certified. Delivery within 30 to 45 working days for production orders.
