The 320-ton metallurgical bridge crane used in foundries is a key piece of equipment specifically designed for lifting high-temperature molten metals (such as molten steel and molten iron) in smelting workshops. Its working level is generally A7 to A8 to match its high-intensity and high-risk operating characteristics. Weihua Group possesses mature products and extensive project experience in the field of 320-ton casting cranes, with its products characterized by high safety, high reliability, and adaptability to harsh working conditions.
320-ton Metallurgical Bridge Crane Product Structure and Technical Features
Weihua's 320-ton casting cranes primarily employ either a four-beam four-rail or a four-beam six-rail structure, customized to meet specific working conditions.
Real-world Case: Five 320-ton casting cranes delivered to a steel company in 2025 utilized a four-beam four-rail structure and optimized the main gearbox, enabling interchangeability between trolley wheels and ensuring the safety and stability of four-wheel drive.
Process Highlights: Weihua previously developed a 320-ton casting crane with a four-beam six-rail articulated structure, employing "integral bridge frame machining technology" and "secondary assembly technology" to ensure the machining accuracy and stability of large-span structural components.
