The safety requirements for electric hoist steel wire ropes are that the diameter of the steel wire rope should generally not be less than 6mm. It is not allowed to use extended steel wire ropes for lifting steel wire ropes. Steel wire ropes used for lifting molten metal should be protected against radiation or splashing onto the steel wire rope. At this time, the steel wire rope should use a metal core or steel wire rope core rope. When fixing the end of the steel wire rope with a rope clamp, the link strength should be ensured to be not less than 85% of the tension of the slope section of the steel wire rope; The number of rope boundary cards should not be less than 5. When using braided links, the length of the braided link should not be less than 15 times the rope diameter and not less than 03m. The strength of the link should not be less than 75% of the tensile force of the slope section of the Aoyu steel wire rope. When connecting with wedges or sleeves, the wedges should be cast with ductile iron, and the strength of the link should not be less than 75% of the breaking force of the steel wire rope.
