APPLICATION SCENARIO

Double Girder Ladle Crane for Molten Metal Handling

The double girder ladle crane is made for steel plants, foundries, and metallurgical factories. It works in high heat, lifts heavy loads, and handles molten metal safely.

Main Uses

1. Steelmaking Workshops

Moves molten steel from furnace to ladle or casting area.
Works with very hot metal (up to 1600°C).
Keeps ladles steady to avoid spills or tipping.

2. Foundry and Casting Work

Pours molten metal into molds.
Supports continuous casting with accurate lifting.
Resists heat, dust, and metal slag.

3. Steel Plants and Rolling Mills

Carries hot ladles between furnace, ladle furnace, and tundish.
Moves slag pots during refining.
Uses anti-sway tech for smooth travel.

4. Heavy Lifting in Metallurgy

Handles frequent work in busy workshops (A6, A7 duty class).
Also lifts scrap, ingots, and billets.
Can add walkways, lights, and other tools for easier use.

Made for Harsh Conditions

✅ Heat Resistance – With heat shields and special materials
✅ Dust Protection – Strong parts for long use
