A cable reducer is a device used to decrease the speed of cable movement and increase torque, commonly employed in various types of machinery, particularly in situations where controlling the speed and force of cable movement is necessary.

The cable reducer achieves the functions of cable deceleration and increased torque through a gear reduction mechanism. It typically consists of key components such as the input shaft, planetary gear mechanism, and output shaft. The input shaft connects to the motor to transfer power, the planetary gear mechanism is responsible for deceleration and torque amplification, and the output shaft transmits power to the driven equipment.
