Typical Applications / Industry Use Cases

Double girder ladle cranes are built to handle the toughest jobs in steel mills and foundries. They’re not just lifting machines — they keep production moving safely and efficiently in high-temperature, heavy-duty environments.

These cranes are used wherever molten metal needs to be moved with precision and reliability. From casting lines to continuous operations, they provide consistent performance shift after shift.

Common Applications

• Steel Mill Casting Lines: Move molten steel from furnaces to molds safely and efficiently.
• Foundries and Metallurgical Plants: Handle ladles with molten metal or other high-temperature materials.
• Continuous Casting Operations: Support uninterrupted workflows in modern steel production.
• Heavy Molten Ladle Handling: Lift and transport large ladles with high accuracy, reducing risk to operators and equipment.

At a mid-sized steel mill, a QDY double girder ladle crane was installed to handle 50-ton molten steel ladles. The crane’s heat-resistant design and precise controls allowed operators to reduce ladle transfer time by 15%, while also minimizing wear and tear on the equipment.
