Explosion Proof Manual Chain Hoist
Explosion-proof manual chain hoists are reliable and cost-effective lifting devices specifically engineered for hazardous environments where flammable gases, vapors, or combustible dust may be present.
These hoists are designed to eliminate potential ignition sources by using spark-resistant materials and a purely mechanical operation, ensuring safe lifting without electrical risks in explosive atmospheres.
MecBase is a professional manufacturer, supplier, and exporter of explosion-proof manual chain hoists in China, delivering high-quality and dependable lifting solutions for hazardous environments across oil & gas, chemical processing, mining, and other industrial sectors worldwide.
Built for maximum safety, durability, and simplicity, our manual chain hoists require no power supply, offer stable lifting performance, and provide long service life with minimal maintenance. They are ideal for low-frequency lifting applications, emergency operations, and locations where electrical equipment is restricted or unavailable.

Notes
- Test Load (kN): Indicates the load used during safety testing (typically 1.5× rated capacity)
- Max Hand Force: Required pulling force for manual operation
- Load Chain Falls: Number of chain strands supporting the load (higher capacity → more falls)
- Extra Weight per Meter: Additional weight for every 1 m increase in lifting height

Hazardous Area Classification
Gas Explosion Environments (per GB 3836.14-2000)
- Zone 1: Explosive gas atmosphere may occur during normal operation
- Zone 2: Explosive gas atmosphere is unlikely, and if it occurs, it exists only briefly
Dust Explosion Environments (per GB 12476.3-2007)
- Zone 21: Combustible dust-air mixtures may occur occasionally
- Zone 22: Combustible dust appears infrequently and exists for short durations

FAQs About Explosion Proof Manual Chain Hoists
They typically rely on non-sparking materials rather than electrical protection, but certification may still be required depending on project standards (ATEX/IECEx).
Common materials include:
- Copper alloy hooks
- Bronze components
- Anti-spark treated steel
They are best suited for intermittent or low-frequency lifting, not continuous production.
