Strength-resistance to breaking The wire rope should be strong enough to handle the maximum potential load including safety factors
2. Resistance to bending fatigue Fatigue is caused by repeatedly bending rope around drums, sheaves, etc. A wire rope with strands made up of many small wires will be more resistant to fatigue, but less resistant to abrasion
3. Resistance to vibrational fatigue Energy is absorbed at the end fittings or at the tangent point where the rope contacts the sheave
4. Resistance to abrasion Abrasion occurs when a rope is dragged over the ground or other surfaces. A wire rope with strands made of fewer, larger wires will be more resistant to abrasion, but less resistant to fatigue
5. Resistance to crushing During use, a wire rope may encounter crushing forces or be struck against hard objects. This can cause the rope to become flattened or distorted, resulting in premature breakage. Wire rope must have sufficient lateral stability to withstand the crushing pressures it may encounter. Regular lay ropes have greater lateral stability than Lang's lay, and six strand wire ropes have greater lateral stability than eight strand
6. Reserve strength Combined strength of all the wires contained within the strands
