Automatic Steel Coil Circumferential Strapping Machine
Advanced Horizontal Coil Packaging Solution for Cold Rolled Steel Lines
Specially engineered for horizontal steel coils with axial conveying, this high-performance fully automatic strapping system integrates a premium **FHOPE FP31 strapping head**, a heavy-duty sword-notching track, and a high-capacity strap dispenser. Designed for seamless integration into automated production lines, it delivers reliable, unmanned operation for heavy-duty metallurgy environments.
Core Technical Advantages
FHOPE FP31 Heavy-Duty Head
Engineered for high-intensity industrial applications. Wear parts feature a significantly longer service life compared to standard imported alternatives, minimizing unexpected downtime.
Innovative Sealless Joint Technology
Utilizes a German-engineered 3-row, 6-point punch sealless joint. Eliminates the cost of traditional metal seals, lowers failure rates, and ensures strong, high-integrity joint strength (≥75% matrix strength).
High-Efficiency Pneumatic System
Delivers an exceptional tension force of up to 20,000N to prevent strap slippage while ensuring high feeding/retracting speeds up to 1.7m/s for optimized cycle times.
450kg Jumbo Strap Dispenser
Supports oscillating-wound jumbo strap coils up to 450kg. Equipped with a dedicated jib crane and electric hoist for rapid coil changes, drastically reducing tail waste and coil-change frequencies.
