[0003] The motor in the steel cable winding device serves as a power source. The motor transmits power to the winding device through a drive shaft. After the motor is started, the power is transmitted to the winding shaft through a transmission device, causing the winding shaft to start rotating. With the rotation of the winding shaft, the steel cable gradually winds around the winding shaft under the guidance of the guide mechanism. During the winding process, constant tension and speed need to be maintained to ensure that the steel cable is neatly and tightly wound.
