(1) Impact

The impact force comes from the outside, and the short-term huge impact force will damage the cross-sectional area of the wire rope for port machinery; or rope strand or steel wire. Impact resistance refers to the ability of the wire rope to resist sudden external forces. When the wire rope is deformed or partially broken due to sudden impact, the steel wire in the rope will be difficult to move and slide normally, and the tension will be greatly reduced, resulting in a decrease in the overall performance of the wire rope.

(2) Stability

Stability usually refers to the purpose and working performance of wire ropes used in port machinery.

(3) Flexibility

Flexibility refers to the difficulty of the port machinery to bend the wire rope into a curved shape. An important factor affecting the bending performance is the diameter of the wire rope. The larger the diameter, the worse the curvature; followed by the strand structure, technical components and core structure.

(4) Strength

When the wire rope used in the port machine breaks under the action of a certain gravity, this value is called the breaking force. The sum of the breaking forces refers to the sum of the breaking forces of all steel wires. When using, it is important to choose a wire rope with corresponding strength according to the breaking force of the wire rope and its own requirements. It should be noted that the strength must be less than the small breaking force of the wire rope.

(5) fatigue resistance

The breaking strength of the wire rope for port machinery is qualified, but the fatigue resistance is poor and unqualified. Due to the poor fatigue resistance of the wire rope, it is easy to break during use, causing safety hazards and losses.

(6) Wear resistance

The wear resistance mainly depends on the structural design and process of the wire rope for port machinery. Therefore, reducing the number of strands of the wire rope for port machinery can improve its wear resistance.

(7) Corrosion resistance

Corrosion resistance refers to the corrosion resistance of steel wire ropes used in port machinery. The main reason for determining the corrosion resistance of wire ropes for port machinery is the composition of the material. Stainless steel materials containing chromium, nickel and molybdenum generally have excellent corrosion resistance.

(8) Resistance to metal loss and deformation

Metal loss refers to the wear of the external steel wire of the steel wire rope used in the port machinery during the actual operation; metal deformation refers to the change of the shape of the external steel wire of the steel wire rope. The corrosion resistance of metals is actually wear resistance; the general deformation of metals is called "hammering", and the exposed side is like being hammered by a hammer.

(9) Residual stress

Residual stress refers to the residual stress of the wire rope for port machinery due to various deformations during the forming process. Residual stress is the main cause of fatigue failure of wire rope. These stresses amplify the small cracks in the steel wire during repeated deformation, causing the cracks to become larger and larger, causing the steel wire to break, and eventually leading to the failure of the steel wire rope. The residual stress in the rope can be eliminated by machinery or heat treatment; the post-deformation and pre-deformation of the wire rope for port machinery in the post-laying stage and before laying can effectively reduce the stress in the wire rope for port machinery.
