The cable is supported by the two idler rollers 4. During the cable pulling process, the rolling friction between the cable and the idler rollers 4 replaces the sliding friction between the cable and the cable hook, thereby reducing the wear on the cable insulation during cable laying, avoiding leakage accidents, and improving safety. Moreover, the rolling friction resistance is smaller, making it easier to manually pull the cable, thus effectively improving the efficiency of cable laying in mine roadways.
