📄 Product Description
Product Introduction
The YZS Type Four Girder Casting Crane is a heavy-duty overhead crane designed for extra-heavy steel mill applications requiring lifting capacities from 100 to 300 tons. Unlike the standard double girder design, this crane features a unique four-girder (four beam) structure providing exceptional strength, stability, and safety for critical molten metal handling operations. The crane is built with high-strength Q235B and Q345B steel plates and manufactured to DIN/FEM international standards. All steel undergoes full pretreatment including sand blasting, primer spray, and drying to eliminate internal stress and enhance anti-corrosion performance. The YZS type four girder casting crane is produced with advanced German Messer CNC plasma cutting for precision, intelligent welding robots for superior weld quality, and a large car-bottom natural gas annealing furnace for post-weld stress relief.
Key Features
- Four Girder Design: Extra-heavy duty four box girder structure for 100-300 ton lifting capacity, designed to DIN/FEM standards with Q235B/Q345B steel
- Full Steel Pretreatment: Sand blasting → primer spray → drying production line eliminates internal stress and improves anti-corrosion adhesion
- German CNC Precision Cutting: Messer CNC plasma cutting machine from Germany ensures <1mm deviation, achieving top-level industry precision
- Intelligent Welding Robot: First enterprise in China to use welding robots; advanced Ar+CO2 MAG welding for internal joints and automatic submerged-arc welding for external joints
- Radiographic & Ultrasonic Testing: 100% inspection of all welding joints and fillet welds to ensure flawless quality
- Large Annealing Furnace: Natural gas car-bottom 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 structural precision
- Epoxy Zinc-Rich Painting: 120μm thick (1 bottom + 2 sides) for long lifespan and corrosion resistance
Applications
The YZS type four girder casting crane is specifically designed for the most demanding steel mill and foundry applications requiring extra-heavy lifting capacities. With its 100-300 ton capacity and four-girder design, it is ideal for: large steelmaking converter shops for hot metal charging and ladle handling; continuous casting plants for heavy molten steel ladle lifting and rotating; large foundry workshops for iron and steel pouring operations with extra-heavy ladles; heat treatment plants for heavy component handling; and integrated steel plants requiring high-capacity material handling solutions. The crane can be customized with electromagnetic lifting beams, grab buckets, ladle rotating devices, and remote control systems for maximum operational efficiency.
