Steel Cord Conveyor Belt

The steel wire core conveyor belt is a rubber conveyor belt with steel wire as the skeleton. It has the advantages of high tensile strength, good impact resistance, long service life, small elongation in use, good troughing and good flexural resistance, and is suitable for long-distance, large-distance and high-speed material transportation. The product is composed of core rubber, steel wire rope, covering layer and edge rubber.

PRODUCT DETAILS

The steel wire core conveyor belt is a rubber conveyor belt with steel wire as the skeleton. It has the advantages of high tensile strength, good impact resistance, long service life, small elongation in use, good troughing and good flexural resistance, and is suitable for long-distance, large-distance and high-speed material transportation. The product is composed of core rubber, steel wire rope, covering layer and edge rubber.

Features:

  1. High allowable strength and high safety factor;
  2. Minimal elongation and short tensioning travel distance;
  3. Strong combination of steel wire rope and rubber, excellent dynamic performance;
  4. Soft belt body, good troughing and good linear running performance;
  5. Excellent impact resistance;
  6. Reliable joints and long service life.
