Premium Explosion Proof Wire Rope Electric Hoists are high-safety lifting devices engineered for flammable and explosive hazardous environments. Compliant with FEM standards and ATEX 2014/34/EU directives, they hold ATEX and IECEx certifications for safe operation in Gas Zone 1/2 and Dust Zone 21/22. With stable lifting and precise positioning, they are widely used in petrochemical, gas, pharmaceutical, metallurgical, grain processing, lithium battery and other industries with explosive gas or combustible dust.
Product Features of ZE Premium Explosion-Proof Wire Rope Electric Hoists
Modular Design & Easy Maintenance
Featuring full modular structure and standardized key components for easy assembly, disassembly and upkeep. Universal core accessories reduce spare part costs and shorten downtime. Independently sealed core parts prevent single faults from affecting overall operation. Fully enclosed oil-bath lubricated gearbox achieves lifelong lubrication with no routine maintenance needed.
Compact Structure Saves Workshop Space
Built with low headroom design to maximize indoor space utilization. It weighs 15%-30% less than conventional hoists of the same specification, lowering workshop load-bearing requirements and construction expenses.
Dual Explosion-proof Certifications Ensure Safety
Certified with both ATEX and IECEx standards. Suitable for gas hazardous Zone 1(IIC T4)/Zone 2(IIC T3) and dust hazardous Zone 21/22(IIIC T135°C), with superior protection level compared with regular explosion-proof hoists.
Variable Frequency Control for Millimeter-level Positioning
- Standard dual-speed control, optional variable frequency stepless speed regulation
- Lifting speed range: 0.1–10 m/min, minimum 0.05 m/min
- Optional anti-sway system minimizes cargo swing for safer handling
- Wireless remote control available to keep operators away from dangerous areas
Core Components of ZE Premium Explosion Proof Wire Rope Electric Hoists
Lifting Motor
- Fully enclosed flameproof Ex d asynchronous motor with excellent explosion-proof adaptability.
- Cast aluminum alloy housing plus copper heat dissipation structure boosts heat dissipation efficiency by about 40% and cuts weight by 25%, ensuring stable operation at high temperatures.
- High-strength aluminum alloy shell, Class F insulation, maximum permissible temperature up to 155°C.
- Built-in overheat protection and alarm system; it automatically slows down or shuts down under abnormal temperature to avoid component aging failure.
Gear Reducer
- Fully enclosed maintenance-free lubrication design, fitted with precision hardened gears.
- Gears are carburized and quenched to HRC58-62, finished by CNC grinding. Running noise below 75dB with transmission efficiency over 96%.
- Housing made of cast steel or ductile iron, tensile strength over 3 times that of ordinary gray cast iron, capable of resisting severe impact in explosion-prone areas.
Steel Wire Rope & Drum
- European-style compact drum ensures neat multi-layer rope winding without disorder.
- Side-mounted drum flushes with main beam to save vertical installation space.
- Anti-static steel wire rope eliminates static friction sparks, ideal for dust explosion-proof environments.
Hoist Hook
- Made of high ductility G20Mn manganese steel with outstanding impact resistance and durability.
- Forged structure features far higher tensile strength than cast hooks, eliminating internal pores and enhancing toughness against sudden impacts.
- High-density copper plating over 60 microns thick prevents spark generation from collision contact.
- All hooks pass static load test at 1.25 times rated load before delivery.
Explosion-proof Electrical Control Box
- Dual isolation via flameproof enclosure and flame path, fully sealed to eliminate external ignition risks.
- Max IP65 protection grade, fully dustproof and resistant to high-pressure water jet washing.
- Adopts dedicated explosion-proof electrical parts with optimized heat dissipation performance.
- Modular design features compact size and neat wiring layout.
Travelling Wheels
- Made of stainless steel to completely avoid friction spark risks.
- Treated by vacuum quenching and low-temperature tempering, surface hardness reaches HRC55-60 for stable performance and long service life.
