The invention discloses a cable winch with a hysteresis tension cradle frame. Both ends of the cradle frame body are rotatably connected to the winch frame through rotating shafts, and a collector ring is arranged on one of the rotating shafts. A hysteresis brake is provided, the collector ring is electrically connected to the hysteresis brake, a large synchronous wheel is connected to the coil, and the hysteresis brake drives the large synchronous wheel to rotate synchronously. The advantages of the present invention are: using the hysteresis brake to provide a stable damping method, to realize the constant and stable pay-off tension of the cable on the reel, the tension of each cable on each cradle frame remains consistent, and the cost of the hysteresis brake is one-time The investment and maintenance cost are almost zero; the trouble of manual adjustment in the later stage is eliminated; the tension adjustment is convenient, saves time and labor, and is intuitive and easy to understand. The tension on each cable is digitally displayed and can be adjusted in real time, which can meet Stranding requirements for highly flexible cables.
