When the hook is placed in the lowest position, why should the wire ropes on both sides of the drum
Because the end of the wire rope is fixed on the drum by the pressure plate, in order to prevent the wire rope from being pulled out from under the pressure plate due to excessive tension or breaking the pressure plate screws and causing accidents such as falling, it is generally required that the steel wire ropes on both sides of the drum should be kept at least 3 times. This can ensure a large friction force between the steel wire rope and the drum, thereby reducing the tension of the pressure plate.
