Steel Cord Belt Structure

STEEL CORD CONVEYOR BELT

Engineered for high-performance and absolute safety, the Fortis Steel Cord belt offers a formidable combination of high tensile strength and minimal operational elongation. We utilize a superior vectorized galvanized wire rope core, creating a product highly resistant to shock and preventing de-bonding. This optimized design ensures perfect balance during high-speed, long-distance conveying operations. For proactive maintenance and safety, Fortis belts are fully inspectable via X-ray non-destructive testing (NDT).

Application Fields

The Fortis belt is the optimal solution for various fields including coal, mining, ports, metallurgy, electric power, and chemical industries, where large-scale material handling over extreme distances and at high speeds is required.

Key Performance Characteristics
  • Extreme Tensile Strength: Powering long-haul and large-span systems.
  • Minimal Elongation: Requires a significantly shorter take-up travel distance.
  • Small Drive Pulley: Allows for smaller, cost-saving equipment design.
  • Superior Cord-to-Rubber Adhesion: Ensures long-term reliability and prevents cord pull-out.
  • Excellent Troughability: Forms deep troughs to maximize loading and eliminate spillage.
  • Predictive Maintenance: Fully inspectable via X-ray NDT without downtime.
