Product Application

        The fully automatic hydraulic tensioning device is mainly used to maintain a constant tension of the conveyor belt, solve the problem of tension imbalance caused by load fluctuations, temperature changes, or belt extension, and prevent faults such as slipping, deviation, and belt breakage.

         Its core functions include:Dynamic response: Real time monitoring of changes in conveyor belt tension, automatic compensation of relaxed or overly tight states through hydraulic systems, ensuring stable tension during start-up, operation, and braking stages;

        Buffer protection: Absorbs the impact load during the start and stop of the conveyor, reducing the instantaneous impact on core components such as motors and reducers;

        Extend lifespan: By optimizing tension distribution and reducing abnormal wear of the belt and drum, the lifespan of the conveyor belt can be extended by 30% -50%;        

        Energy saving and consumption reduction: Avoid additional friction losses caused by excessive tension, and reduce system energy consumption by 10% -15%.        

        Especially suitable for complex working conditions such as long distances (>500m), large inclination angles (>15 °), or heavy loads (>2000t/h), it is the core component that ensures the safe and efficient operation of the conveying system.

        Widely used in fields such as chemical engineering, waste treatment, electricity, coal mining, mining, building materials, non-ferrous metallurgy, raw material storage yards, ports and terminals.
