STEEL CORD CONVEYOR BELT

APPLICATIONS

Steel cord conveyor belts are widely used for high-strength, long-distance, and heavy-load material transport. They are also suitable for short-distance, high-strength transportation of materials on certain occasions.

FEATURES:

  • • High tensile strength for large span, long-distance transportation of materials.
  • • Low elongation, requiring a short take-up stroke distance.
  • • Smaller drive pulley diameters due to excellent fatigue resistance.
  • • Excellent penetration of rubber between the individual cord filaments, ensuring superior adhesion.
  • • Uniform cord tension achieved through advanced manufacturing techniques.
  • • Excellent trough-ability, allowing increased load capacity and reduced spillage.

ST NUMBER:

Guaranteed tensile strength of steel cord in kg x no. of steel cords

Belt width in cm

The ST number represents the guaranteed tensile strength of the steel cords per centimetre of belt width. Tensile strength varies according to cord diameter and pitch, allowing belts to be manufactured to suit specific operational requirements.

Maximum tension ratings indicated in the tables apply under optimal operating conditions and should be adjusted for site-specific applications. We are able to design and manufacture steel cord belts to special specifications upon request.
