Wire rope industry is an important branch of manufacturing industry, reflects a national and regional level of manufacturing industry in a certain extent. Europe and the United States, Japan and South Korea and other countries and regions with a long history of development in the steel wire rope industry, advanced technology level.
We first look at the non rotating wire rope working principle, the inner and the outer layers of opposite direction of twist, when the force by the opposite direction of the outer layer, inner layerand outer layer because of its shares to the opposite strand, the rotating force will limit the outer strands, so will be appropriate to reduce the load bearing object in the sky
Strands of adjacent layer of steel wire is point contact state of wire rope, also called non parallel rope (Figure 1). The strandsof the steel wire rope (except the center wire) are all made of the same specifications of steel wire twisted system, each layer of steel wire twisting angles are equal but lay pitch range
