Universal electric hoist
Weiyuan 5-Ton Low-Headroom Explosion-Proof Monorail Electric Hoist

Tagline: ATEX Certified Explosion-Proof Lifting Solution for Hazardous & Volatile Environments
1. Product Overview
Engineered for maximum safety in hazardous industrial environments, the Weiyuan 5-Ton Low-Headroom Explosion-Proof Monorail Electric Hoist is ATEX certified for Zone 1 and Zone 2 gas/dust atmospheres. Featuring spark-resistant bronze-coated hooks, flameproof enclosure motors, and ultra-compact headroom design, this monorail hoist maximizes lifting height in tight overhead clearances while preventing electrical or mechanical ignition risks.
2. Key Advantages & Technical Highlights
- ATEX & IECEx Certified Flameproof Rating: Fully enclosed spark-proof housing, Ex d IIBT4/IIC T4 protection, and anti-static wire ropes ensuring complete operational safety.
- Ultra-Low Headroom Trolley Frame: Specially contoured monorail trolley frame maximizes effective hook lift in low-ceiling plant environments.
- Spark-Resistant Heavy-Duty Components: Includes bronze-plated crane hooks, brass trolley wheels, and copper-clad guide rails to eliminate mechanical friction sparks.
- Integrated Overload & Thermal Protection: Equipped with dual-stage limit switches, PTC motor sensors, and an automatic fail-safe mechanical brake.
