The choice of 4-strand or multi-strand wire rope actually depends on the specific application scenarios and needs. The following is a detailed comparison of the characteristics, advantages and disadvantages between the two:

1. 4-strand wire rope: 4-strand wire rope consists of four wire strands, each strand including multiple wires. It has the following characteristics:

• High strength: 4-strand steel wire rope is stronger than multi-strand steel wire rope and can withstand higher tension.

• High abrasion resistance: 4-strand wire rope is more durable in abrasive environments due to the reduced number of wire strands.

• Easy to bend: Due to fewer wire strands, the 4-strand wire rope is easier to bend and turn, suitable for applications with complex working conditions.

• Smaller size: 4-strand wire ropes are usually smaller in diameter and lighter in weight, reducing the load on equipment and structures.

2. Multi-strand wire rope: Multi-strand wire rope consists of multiple wire strands, each strand usually including 7 or more wires. It has the following characteristics:

• Softer: Multi-strand steel wire rope is softer than 4-strand steel wire rope, and can better adapt to various complex curves and angles.

• Corrosion resistance: multi-strand steel wire ropes are usually galvanized or other anti-corrosion treatment, which has better corrosion resistance.

• Anti-fatigue performance: Since the multi-strand steel wire rope has more steel wire strands, its anti-fatigue performance is better, and it is more suitable for scenes of long-term use and frequent movement.

• Stability: Multi-strand wire ropes are more stable in diameter and weight because they have more strands.

   According to specific application requirements, we can comprehensively consider the above characteristics for selection:

• If the application scene requires high strength and there is large friction and wear, it is recommended to choose 4 strands of steel wire rope;

• If the application scenario is more complex and requires a more flexible and adaptable wire rope, it is recommended to choose a multi-strand wire rope;

• If the application scenario requires steel wire ropes with better corrosion resistance and stability, multi-strand steel wire ropes can be considered for anti-corrosion treatment.

   It should be noted that in practical applications, other factors such as material quality, size and load need to be considered. Therefore, it is best to consult a professional or conduct further evaluation according to specific project requirements before selecting a wire rope.
