Steel Cord Conveyor Belts for Long-Distance and High-Tension Conveying
Hongkun steel cord conveyor belts use longitudinal zinc-coated steel cord reinforcement for long-distance, high-tension, high-capacity, and heavy-duty bulk-material conveying. ST strength rating, cord pitch, cover thickness, rubber compound, transverse reinforcement, splice design, belt width, and roll length are selected according to the conveyor calculation and operating conditions.
Frequently Asked Questions
Key questions about carcass selection, ST strength rating, longitudinal tear protection, splicing, and technical quotation.
Steel cord construction is generally considered for conveyors involving high working tension, long centres, large lifts, wide belts, heavy loads, or low operational elongation requirements. EP fabric belts remain suitable for many short- and medium-distance systems. Final selection should be based on the conveyor calculation.
The ST rating should be selected from the calculated maximum belt tension, required safety factor, conveyor geometry, lift, capacity, belt width, drive arrangement, take-up system, pulley diameters, splice design, and applicable standard. Conveyor length alone is not enough to determine the belt strength.
Yes. Breaker fabric, steel mesh, transverse cords, or other reinforcement options can be reviewed for loading zones handling sharp, irregular, or high-impact material. These structures may improve puncture resistance and help slow tear propagation, but they do not replace correct loading design, maintenance, and monitoring.
Splice performance depends on the approved splice design, cord preparation, step length, rubber compatibility, vulcanization temperature and pressure, workshop conditions, alignment, curing control, pulley diameters, operating tension, installation quality, and inspection.
Please provide the conveyor centre distance, horizontal length, lift, capacity, material density and size, belt width, speed, calculated working tension, drive and take-up arrangement, pulley diameters, cover thickness, compound requirements, tear risk, splice requirement, roll length, and applicable standard.

Steel Cord Conveyor Belt Compounds and Structural Options
Hongkun steel cord conveyor belts use longitudinal zinc-coated steel cord reinforcement for long-distance, high-tension, high-capacity, and heavy-duty bulk-material conveying. Cover compound, ST strength rating, transverse reinforcement, sensor-loop configuration, cover thickness, and splice design are selected according to the conveyor calculation and operating conditions.
Available Cover Compound Options
Final compound selection depends on the conveyed material, operating environment, temperature, safety requirements, abrasion, and chemical exposure.
Standard Steel Cord Construction
Designed for long-distance and high-tension conveying where the main requirements are high longitudinal tensile strength, low operational elongation, dimensional stability, and reliable splice performance.
Transverse Reinforcement Construction
Breaker fabric, steel mesh, transverse cords, or other reinforcement layers can be reviewed to improve puncture resistance and help slow longitudinal tear propagation in high-impact loading zones.
Embedded Sensor-Loop Construction
Conductive sensor loops can be incorporated for use with a compatible longitudinal tear-detection system. If a loop is damaged, the external monitoring system can identify the event and trigger an alarm or configured conveyor response.
