Abstract: This invention relates to an improved holdback mechanism for high-inclination belt conveyor systems, particularly those used in steel plants and other bulk material handling industries. The system integrates a sprag-type backstop clutch with a turbo pulley system and a hydraulic drive, effectively preventing belt reversal during power outages or mechanical failures. The sprag backstop clutch automatically engages to stop the belt from moving backward, thereby preventing material pile-ups and equipment damage. The system is designed for durability and minimal maintenance, featuring heavy-duty components such as a turbo-designed drive pulley assembly, plummer blocks, and a robust support bracket. The modular design allows for easy integration with existing conveyor systems, enhancing operational safety and efficiency. The invention has been tested under various load conditions, demonstrating its effectiveness in preventing belt reversal and ensuring reliable operation in harsh industrial environments.
