Performance advantages of eight-strand steel wire rope

In my country's existing wire rope production and application fields, the number of 6-strand wire rope product categories is still far higher than the number of 8-strand wire rope product categories. With the increasing rationalization of market demand and the increasing demand of market demand, people gradually have a deep understanding of the superiority of the 8-strand steel wire rope product category in terms of structure and performance. Therefore, the future market demand will make the potential demand of the 8-strand wire rope product category present increasingly obvious market development prospects.

Performance advantages of 8-strand steel wire rope

Compared with 6-strand steel wire rope, the 8 strand steel wire rope product category has the advantages of machine effects due to its performance:

1. Determined by the structure of the 8 strand steel wire rope itself, the increase in the number of strands of the steel wire rope reduces the diameter value of the rope-making steel wire and increases the wire quantity. While achieving the comprehensive improvement of the mechanical properties of the rope-making steel wire, it also makes the wire rope softer. In order to improve, the necessary conditions are provided for the extension of the service life of the wire rope and the improvement of the application effect.

2. Due to its strand structure, the 8-strand steel wire rope has an increased contact surface with the sheave in practical applications, which reduces the pressure per unit area of the sheave, that is, the pressure, and at the same time makes the sheave to rib the steel rope. Dispersion leads to stress, which is another reason why the service life of 8-strand wire rope is higher than that of 6 strand wire rope.

3. The rope structure is evolving to a complex multi-filament structure, so that the strands are twisted with different diameter steel wires and the same lay length. The wires of each layer are in a line contact state, so that the wire rope in the working state The contact stress on the steel wire is greatly reduced, and no secondary bending stress is generated in the bending state, especially in the working state where the forward bending and the reverse bending are frequently switched in a short time, it has more structural advantages and application effects. Therefore, this kind of wire rope has many advantages such as compact structure, high fatigue resistance, large breaking force and long service life.

2. Expansion of the application field of 8 strand wire rope
Because 8-strand steel wire rope is superior to 6-strand steel wire rope in many aspects such as service performance, its application field shows a trend of continuous expansion. At present, the increasingly expanding application fields mainly include electric shovel hoisting rope, cantilever beam support rope, mooring rope, ship towing rope, sunken ship salvage rope, elevator rope, truck crane rope, port handling machinery rope .
