Characteristics:
1．High tensile strength：the belts a re suitable for large span, long distance transportation of materials.
2．Small elongation in use: the belts need only a very short take-up stroke distance.
3．Small diameter of drive pulley：the belt body has a layer of longitudinally arranged steel cords as its skeleton，and thus is resistant to flex fatigue. Therefore drive pulley of smaller diameter can be used to make the equipment smaller.
4．High adhesion between rubber and steel cord：the steel cords a re coated with zinc on their surface, and also the rubber used has the property of good adhesion with steel cords. Therefore, the rubber is tightly adhered to the steel cords and is resistant to shock and difficult to drop, so the rubber belts are long in life.
5．Even tension of steel cords：out of our advanced techniques in manufacturing, the steel cords are very evenly arranged and have the same tension, so the belts are well balanced in running and difficult to run away.
6．Good troughability：As the belt body has no transverse skeleton, it is easy to form a deep trough, so the belts can load more materials and prevent the materials from escaping.
7．Inspection of the belt with X-rays: Users can use X-rays to inspect damages of the skeleton steel cords on the convey or machines to prevent accidents from happening
Primarily deployed in mining operations, port logistics, and large-scale construction projects, steel cord conveyor belts excel in long-distance transportation scenarios where conventional fabric-reinforced belts would fail. Their unique structural composition allows for horizontal conveying distances exceeding 20km while maintaining minimal elongation rates below 0.25%, making them indispensable for coal mining conveyors and quarry material handling systems. The interwoven steel cords provide exceptional dimensional stability even under full load conditions, significantly reducing maintenance requirements compared to traditional textile-reinforced alternatives.
