Explosion Proof Electric Chain Hoists Product Introduction
Explosion proof electric chain hoists are designed for safe lifting in hazardous environments. Exposed explosion-proof components are made of special spark-resistant materials, ensuring that friction or impact between parts will not generate mechanical sparks during operation. This prevents ignition of flammable gases and effectively reduces the risk of fire or explosion. With a high-quality chain transmission system, the hoist provides stable and reliable lifting for various heavy-duty material handling tasks.
These explosion proof electric chain hoists support fixed suspension or trolley suspension configurations and can be equipped with a manual or electric explosion-proof trolley for smooth travel along an I-beam track. The integrated axial structure combining the gearbox, suspension bracket, and motor improves sealing performance and simplifies maintenance, making the hoist suitable for outdoor environments and dusty workplaces. It is widely used in factories, warehouses, docks, construction sites, and other facilities, especially in low-headroom areas or environments with dust, humidity, or corrosive gases.
Explosion Proof Electric Chain Hoists Features
- Suitable for Zone 1 or Zone 2 hazardous areas with Class B explosive atmospheres and T4 temperature group inside industrial facilities.
- Disc brake motor – strong power output, compact size, reliable and responsive braking performance.
- Reducer with standard module cylindrical gears – compact structure, easy maintenance, lightweight, and high transmission efficiency.
- High-strength steel chain – wear-resistant, ensuring stable and safe lifting.
- Thickened cast housing – impact-resistant, durable, and designed for long service life.
- Explosion-proof motor – provides effective protection in case of motor failure within enclosed environments, reducing the risk of accidents.
- Limit switch protection – automatically stops the hoist when the upper or lower limit is reached to prevent overload or over-travel.

Explosion Proof Environment Definitions
Different international standards define hazardous environments in different ways. The following table summarizes common classifications used in ATEX Certification and CSA Certification systems.
| Norma | Klasifikace | Popis |
|---|---|---|
| ATEX | Zone 1 | Explosive gas atmosphere may occur occasionally during normal operation. |
| ATEX | Zone 2 | Explosive gas atmosphere is not likely during normal operation, but may occur briefly. |
| CSA / US | Class 1 | Areas where flammable gases or vapors may be present and could form an explosive mixture. |
| CSA / US | Division 2 | Hazardous substances are not normally present but may appear under abnormal conditions. |
| CSA / US | Zone 2 | Explosive gas atmosphere does not normally exist. |
| Norma | Klasifikace | Popis |
|---|---|---|
| ATEX | Zone 21 | Combustible dust clouds may occur occasionally during normal operation. |
| ATEX | Zone 22 | Combustible dust clouds are not likely in normal operation but may appear briefly. |
