Solução QC para Ponte Rolante Eletromagnética e Ponte Rolante de Fundição para Projeto de Planta de Aço no Vietname

Visão Geral do Projeto

In September 2025, a major Vietnamese steel manufacturer planned to upgrade its blast furnace system to enhance material handling efficiency and operational safety. Consequently, they consulted Weihua for reliable lifting equipment, requiring solutions capable of operating under high-temperature, heavy-load conditions to cover the entire workflow from scrap steel processing to molten metal transfer.

Based on the client’s requirements, Weihua provided a solution comprising QC electromagnetic overhead cranes (50 tons/10 tons) and YZ casting bridge cranes (100 tons/32 tons).

Suporte técnico e de instalação da Weihua

The project was completed within 35 days, encompassing design, manufacturing, testing, and shipment. The Weihua service team provided full-process support to ensure smooth project execution from factory to site. The factory also conducted comprehensive acceptance testing, including 72-hour continuous simulated steelmaking operation, IP55 protection rating verification, and salt spray testing to ensure suitability for coastal environments.

We provided advance on-site support for this project, dispatching engineers to the customer’s location prior to equipment delivery to coordinate installation and commissioning. Additionally, on-site training was provided for both operators and maintenance personnel.

After-Sales Support

• Remote monitoring using real-time operational data
• Predictive maintenance alerts for critical components
• Local spare parts support in Vietnam
• Long-term service and technical consultation

Resultados do projeto

Based on on-site operational feedback, the crane operated smoothly during scrap steel lifting and molten steel transportation, exhibiting good positioning accuracy and operational stability. The equipment did not experience any abnormal shutdowns in continuous operation and required minimal maintenance, demonstrating its ability to adapt to the daily production rhythm of the steel plant.
