When the cable is subjected to fatigue wear test, the lifting mechanism 100 moves downward to drive the water tank 300 to move downward. When the water tank 300 moves downward, the gear 630 is driven by the tooth plate 631 to drive the middle transmission rod 610 to rotate, and then the dry grinding roller body 710 is driven to flip through the continuous transmission tooth plate 640 and the sprocket 650 to make it flip to the end of the counterweight assembly 400. At this time, it is only necessary to pass the cable around the surface of the dry grinding roller body 710 and the wear plate 720 and reel it on the surface of the reel body 251. At this time, the wear fatigue test of the cable under different environments can be completed without removing the water tank 300.
