4-strand and multi-strand are two common constructions of wire rope. Below is a comparison and analysis of 4-strand and multi-strand wire ropes to help you choose the right one for your specific needs.

   4-strand wire rope: 4-strand wire rope consists of 4 twisted strands, and each twisted strand is twisted from 7 or more thin steel wires. Here are some features and advantages of 4-strand wire rope:

1.            Strength and durability: 4-strand steel wire rope is relatively strong and has high strength and durability. This makes it very reliable in applications that need to carry heavy loads and have high safety requirements.

2.            Stability: Since the structure of the 4-strand steel wire rope is relatively compact and stable, it usually has high compression resistance and torsion resistance. This makes it suitable for working environments that require high stability and reliability, such as lifting, hoisting and construction fields.

3.            Softness: Although 4-strand wire rope is relatively strong, it also has a certain degree of softness. This makes it suitable for applications requiring some bending capability and flexibility, such as bridging, forestry, suspension and bracing, etc.

   Multi-strand wire rope: A multi-strand wire rope consists of multiple strands, each of which is twisted from 7 or more thin wires. Here are some features and advantages of multi-strand wire rope:

1.            Flexibility: multi-strand steel wire ropes are generally softer than 4-strand steel wire ropes, and can adapt to more complex working environments and bending requirements. This makes it suitable for applications requiring high flexibility and bending capabilities, such as lifting, excavating and lifting machinery.

2.            Fatigue resistance: Due to the softness and bending ability of multi-strand wire rope, it usually has good fatigue resistance. This makes it suitable for applications requiring frequent bending and movement, such as lifting and transporting machinery and equipment.

3.            Bearing capacity: Multi-strand wire ropes are relatively flexible, but generally not as strong as 4-strand wire ropes with the same diameter. Therefore, 4-strand wire ropes may be more suitable in working environments that have higher requirements for load-bearing capacity, such as large-scale lifting equipment and high-strength projects.

   To sum up, the choice of 4-strand wire rope or multi-strand wire rope depends on the specific working environment and application requirements. 4-strand wire rope is a better choice if you need higher load carrying capacity, stability and compression resistance, while being able to tolerate less softness. If you need more flexibility, fatigue resistance and bending capacity, and have relatively low load-bearing requirements, multi-strand wire rope may be more suitable for your needs. Before choosing, make sure you understand the specific working conditions and safety requirements and make an informed choice based on these factors.
