Wire contact steel wire rope
The steel wires of wire contact steel wire rope in the strand are in linear contact with each other, with equal lay distance, unequal diameter of each layer of steel wire, which increases metal fault area inside of steel wire rope, low contact stress per unit area of steel wire rope, less prone to wire breakage, wear-resistant, fatigue resistant, high tensile strength, and long service life for the steel wre rope.
Wire contact steel wire ropes are typically applied for vertical shaft lifting, blast furnace hoisting, oil drilling, belt conveying, cable traction, ground cable car, excavator, shovel hoisting, large casting crane, ship loading and unloading, ship tensioning mast and suspension bridge, fishing trawl.
Comparation Wire Contact Wire Rope with Surface Contact Wire Rope
1. Structure: Line contact steel wire rope refers to a structure where each layer of steel wire rope is connected only through winding contact points. Face contact wire rope refers to the situation where each layer of wire rope is in contact with each other while also maintaining parallelism. The difference between the two lies in their different ways of contact. In online contact wire ropes, when a single wire rope is stretched, only the number of contact points on the wire rope participate in the load-bearing capacity, while face contact wire ropes have stronger load-bearing capacity due to the larger contact area between the layers of wire ropes.
2. The characteristics and usage scenarios of wire contact steel wire ropes
Wire Contact Wire Rope: Due to the limited number of contact points between each layer of wire rope, wire contact wire rope has high strength and load-bearing capacity. During use, due to the limited contact points of the wire rope, the friction force is low, making it suitable for mechanical composite rigging with long spans and large load-bearing capacity, as well as the walking mechanism of cranes.
Surface Contact Wire Rope: Face contact steel wire rope has greater flexibility and stability due to the larger contact area between each layer of steel wire rope, as well as greater friction. It is suitable for situations where lateral load resistance and high fatigue resistance are required during operation, such as bridges, tower cranes, and mining equipment.
How to select wire ropes for different usage scenarios?
Wire contact wire rope and surface contact wire rope each have their own characteristics and usage scenarios. Line contact steel wire rope is suitable for mechanical composite rigging with large span and load-bearing capacity, as well as the walking mechanism of cranes.
Surface contact steel wire ropes are suitable for situations that require lateral load resistance and high fatigue resistance during operation, such as bridges, tower cranes, and mining equipment. When using steel wire ropes, it is necessary to choose the appropriate type and specification according to specific needs.
