According to the surface treatment of the steel wire, it can be divided into two types: smooth surface and plated bowl. Smooth steel wire ropes are commonly used in lifting operations.
According to the structure of steel wire rope, it can be divided into point contact rope, line contact rope and surface contact rope.
The diameter of each layer of steel wire of the point contact rope is the same, but the pitch of each layer is different, so the steel wire crosses each other to form point contact, the contact stress is very high during work, and the steel wire is easy to wear and break, but its manufacturing process is simple.
The thickness of the wires in the strands of the wire contact rope is different, and the thin wires are placed in the grooves of the thick wires, and the thick and thin wires are in line contact state. Due to the smaller contact stress of the wire rope in line contact, the service life of the wire rope is long, and the flexibility is increased at the same time. Because the wire rope is relatively dense in contact with the wire, the breaking force of the wire rope with the same diameter is larger. Co-laid wire ropes with the same wire diameter in the strand are also wire-contact ropes.
