Changqiao steel wire rope is a type of steel wire rope used for lifting and transporting heavy items. When selecting the field bridge steel wire rope, it is necessary to comprehensively consider the specific usage situation and needs. The following will provide a detailed introduction on how to choose a suitable field bridge steel wire rope from the aspects of material, diameter, strength, structure, etc.

1、 Material selection

The material of the bridge steel wire rope is one of the key factors. The material of steel wire rope is usually composed of various alloys, such as 6 × 19, 6 × 37, 8 × 19 and 18 × Grade 7. Generally speaking, there are two commonly used materials for steel wire ropes, one is carbon steel and the other is stainless steel.

For field bridges that often work at seaside, chemical plants, and other places, it is recommended to use stainless steel wire ropes to avoid corrosion of the wire ropes. For other locations, carbon steel wire ropes can be used.

2、 Diameter selection

The larger the diameter of the bridge steel wire rope, the stronger its strength and load-bearing capacity. However, the larger the diameter of the steel wire rope, the heavier and less flexible it may be, which may affect the accuracy and efficiency of lifting and handling. Therefore, when selecting the field bridge steel wire rope, it is necessary to balance the relationship between strength and flexibility based on actual needs and choose the appropriate diameter.

For the lifting of large machinery and equipment, it is usually necessary to use wire ropes with larger diameters to ensure their safety and stability; For the lifting of small items, smaller diameter steel wire ropes can be selected for easy operation and storage.

3、 Strength selection

The strength of the bridge steel wire rope is another important factor. Generally speaking, the working load capacity of a steel wire rope should exceed four times the weight of the suspended object. When selecting the strength of the steel wire rope, factors such as maximum lifting weight, working height, span, and frequency of use need to be considered.

Select steel wire ropes with different strengths based on factors such as the items transported by the bridge and the transportation distance. When selecting a steel wire rope, it is also necessary to determine the safe working load (SWL) used to ensure the safety of the steel wire rope.

4、 Structure selection

The structure of the bridge steel wire rope is also an important factor. The structure of the bridge steel wire rope is usually composed of the inner and outer layers of the steel wire rope. According to the weaving method and proportion of the inner and outer layers, the field bridge steel wire rope includes many different structures, such as 6 ×× 19. 6 × 37, 7 × 19 and 8 × 19, etc.

Different structures have different characteristics and applicability. For example, the more outer layers of a steel wire rope, the stronger its wear and corrosion resistance; The more inner layers, the more flexibility the steel wire rope has. Therefore, when selecting the structure of the steel wire rope, it is necessary to consider the strength, durability, and flexibility required for the usage situation, and comprehensively select the appropriate structure.

In summary, when selecting the bridge steel wire rope, many factors need to be considered, such as material, diameter, strength, and structure. Based on actual needs and usage conditions, taking into account various factors, selecting a suitable field bridge steel wire rope can ensure efficient, accurate, and safe lifting and transportation.
