📄 Product Description
Product Introduction
The YZ Type Double Girder Casting Crane (also known as Foundry Crane or Ladle Crane) is a heavy-duty overhead crane specifically designed for steel mill applications such as molten metal handling, ladle pouring, and casting operations. It features a double welding box girder structure manufactured to DIN/FEM international standards. The crane is built with high-strength Q235B and Q345B steel plates and undergoes full pretreatment including sand blasting, primer spray, and drying to eliminate internal stress and enhance anti-corrosion performance. The YZ type casting crane is produced with advanced German Messer CNC plasma cutting for precision machining, intelligent welding robots for superior weld quality, and a large car-bottom natural gas annealing furnace for post-weld stress relief treatment.
Key Features
- Double Welding Box Girder: Designed to DIN/FEM standards, using Q235B/Q345B steel with full pretreatment (sand blasting → primer → drying) for maximum structural integrity
- German CNC Precision Cutting: Messer CNC plasma cutting machine from Germany ensures <1mm deviation, achieving top-level precision in the industry
- Intelligent Welding Robot: First enterprise in China to adopt welding robots for main beam; advanced Ar+CO2 MAG welding for internal joints and automatic submerged-arc fillet welding for external joints
- Radiographic & Ultrasonic Testing: 100% inspection of welding joints and fillet welds to ensure flawless quality
- Large Annealing Furnace: Natural gas car-bottom annealing furnace (10000×4000×4000mm) — unique capability in China Crane Hometown for stress-relieving treatment
- High-Strength Bolted Assembly: Girder and end beam connected by high strength bolts for precision and structural strength
- Advanced Safety Systems: Overload protection, limit switches, anti-collision, emergency-off, voltage lower protection, and patented anti-swing mechanism
- Epoxy Zinc-Rich Painting: 120μm thick (1 bottom + 2 sides) for long lifespan, beautiful appearance, and corrosion resistance
Applications
The YZ type double girder casting crane is mainly used in steel mills, foundries, and heavy industrial plants for molten metal handling, ladle transportation, and foundry pouring operations. It is designed for high-temperature, heavy-duty environments where reliability and safety are critical. Typical applications include: steelmaking converter shops for hot metal charging and ladle handling, continuous casting plants for molten steel ladle lifting and rotating, foundry workshops for iron and steel pouring operations, and heat treatment plants for heavy component handling. The crane can be customized with various auxiliary mechanisms such as electromagnetic lifting beams, grab buckets, and specialized ladle rotating devices to meet specific production requirements.
