General purpose overhead crane
Weiyuan Weiyuan QD Type Overhead Crane for Steel Mills | Heavy-Duty, Heat-Resistant, High-Performance
Product Overview
The Weiyuan Weiyuan QD Type Overhead Crane for Steel Mill Applications is a specialized, heavy-duty lifting solution engineered to thrive in the extreme conditions of the metal production industry. Built for high-frequency, high-temperature, and dust-filled environments, this crane features a robust double-girder structure for maximum stability and strength. It is equipped with advanced, heat-resistant components, including specialized hoists and motor insulation, to ensure reliable performance when handling molten metal, steel slabs, and coils. This crane is the definitive choice for steel mills demanding uncompromising safety, durability, and efficiency.
Product Advantages
- Engineered for Extreme Environments: Designed with high thermal resistance, dust-proofing, and protective features to operate reliably in the harsh conditions of a steel mill, including proximity to furnaces and casting areas.
- Superior Safety for Critical Lifts: Equipped with redundant safety systems, such as dual brakes on main lifting mechanisms, overload limiters, temperature monitoring, and emergency stops, to ensure the highest level of safety when handling molten metal and other critical loads.
- Robust and Durable Construction: The crane’s structure uses high-strength steel (Q355B or higher) and features a heavy-duty trolley and end carriages, providing exceptional durability and a long service life under continuous, heavy-load operation (A7-A8 work duty).
- High-Performance and Precision: Features powerful motors with variable frequency drives (VFD) for smooth, precise control over all movements. This allows for gentle acceleration and deceleration, minimizing load swing and enhancing operational accuracy.
- Customization for Specific Mill Tasks: Can be configured as a casting crane, charging crane, slab handling crane, or coil handling crane, with specialized lifting attachments like ladles, magnets, or C-hooks to meet the unique demands of each process stage.
Application Scenarios
- Casting Bays: Safely transports and pours ladles of molten steel or iron into molds with precision and stability.
- Furnace Charging: Reliably lifts and feeds scrap metal and other raw materials into electric arc furnaces (EAF) or basic oxygen furnaces (BOF).
- Slab and Billet Handling: Efficiently moves hot or cold steel slabs, billets, and blooms from the continuous caster to the rolling mill or storage yard.
- Rolling Mills: Positions heavy steel sections for entry into rolling stands and transports finished products.
- Coil and Plate Storage Yards: Manages the lifting, stacking, and transportation of heavy steel coils and plates using specialized magnets or C-hooks.
