Broken wire between the various strands of cloth. Maximum number of broken wires in one lay length exceeds 32 (about 20% of the total number of wires of wire rope). Broken wires in one or two strands. Maximum number of broken wires in one lay length exceeds 16 (about 10% of the total number of wires of wire rope). Traction rope wear and its diameter is less than or equal to the nominal diameter of the wire rope 90%. Traction wires have greater wear or corrosion of the surface.
