Shares of
wire rope on each wire can also contact between the state is divided into point contact, line contact or surface contact with three kinds.
1. Point of contact
wire rope: wire diameter are the same stocks. In order to wire the force evenly on each wire around the screw after the helix angle roughly equal, but the twist away from the range, so both inside and outside layer of steel wire cross-cutting, showing point of contact state.
2. Line contact wire rope: stock in the layers of twisted steel from the same inner and outer layer of steel wire in a spiral line contact with each other, showing line of contact state. Line contact wire rope performance than point-contact are greatly improved, so widely used.
3. Sealed wire rope: surface contact with a strand, the outer layer is made with the B-shaped wire, the surface smooth, good wear resistance, with the same diameter as compared to other types of
wire rope, the tensile strength larger, and can withstand lateral pressure, but flexibility is poor, more complex process, manufacturing costs are high, commonly used for carrying cable, such as cable cranes and aerial cableway on the ropes.
