Explain:
1. The wire rope strength listed in the table is 1670N/mm2, rope strength is usually 1570, 1670, 1770, 1870, 1960 N/mm2, safety factor generally take 6, the static safety factor of steel wire rope tension is 3 to 4.
2. The breaking load of wire rope in the listed table is fiber core for FC of the broken wires sum. Metal wire core wire IWR-broken rally sum to ≈ 1.08 times of the fiber core, wire rope breaking force = sum of the minimum breaking load X1.283 (metal core IWR)
3. The Kg/100M value listed in the table is the theory weight of FC fiber core wire rope, but the actual weight of rope fiber core FC is 1.05 of this value, the actual weight of metal core IWR rope is 1.155 of this value.
