The 450 t casting crane custom-built by Henan Mine Crane for a customer is one of the largest, most technically advanced and widest-span four-girder four-rail casting cranes used in electric-furnace steelmaking in China. With high reliability, high safety and a high level of equipment, it mainly handles molten metal in steelmaking and ironmaking plants and has won unanimous praise from metallurgical users.

Product advantages

• Four girders, four rails and a long span for safety and stability — the four-girder four-rail layout with a single large integrated reducer provides greater safety.
• Machined as a whole for a longer service life — the trolley frame is annealed and machined in one piece, giving higher assembly accuracy, smoother operation and longer life.
• Finite element modelling for greater strength — design calculations use FE modelling with equal-strength, equal-life component design, giving better structural and mechanism matching and higher cost-effectiveness.
• Full-crane PLC control and intelligent upgrade capability — the crane is PLC-controlled with an open industrial Ethernet bus and interfaces reserved for intelligent upgrading.
• Full-crane safety monitoring for efficient management — a safety monitoring and management system provides real-time alarms and full-life inspection records, improving safety and productivity.

Henan Mine Crane will continue to leverage its core strengths in new quality productive forces, innovate and develop high-quality, high-performance and cost-effective cranes, provide better service to customers and empower high-quality development of the manufacturing industry with precision manufacturing.
