What Challenges Do Metallurgical Plants Face?

Handling molten metal in metallurgy plants involves:

• 1. Extreme temperatures that can damage standard hoists

• 2. Continuous operations with minimal downtime

• 3. Stringent safety requirements for lifting hot ladles and liquid metal

• 4. Exposure to dust, fumes, and corrosive environments

A standard electric hoist cannot safely and efficiently handle these demands.
