Why should 8 strands be recommended for lifting and unloading steel wire ropes in port?

At present, most of the steel wire rope structure in the port is heavily loaded and unloaded, most of which are 6 or 8 shares in the market. The common 6 strand wire rope has 6*36WS+IWR, 6*29Fi+IWR, tensile strength grade 1770, 1670MPa;

Our suggestion is to gradually select 8 strand wire ropes, such as 8*31WS+IWR and 8*36WS+IWR.

Why do we choose 8 strands, because 8 strands are softer than the traditional 6 strands, and because they are metal cords?

The contact surface between the 8 strand wire rope and the roller and the pulley can be better, and the contact stress between the surface steel wire and the wheel groove can be reduced, and the fatigue resistance can be improved.

8 strands of wire rope are recommended for gantry crane and container ship unloader.

With the continuous deepening and improvement of the wire rope production technology, we have higher requirements for the 8 strand wire rope, and the traditional line contact 8 strands of wire rope in the process of compaction and forging, increase the breaking tension of the wire rope, and further improve the service life of the wire rope, that is, the surface contact we say. A wire rope.

The common models of surface contact wire rope used in port lifting or loading and unloading equipment are 8*K36WS+IWR, 8*K31WS+IWR, and 8*K26WS+IWR.

We should not only choose the right wire rope, but we should consider the requirements of the reels and pulleys on the wire rope, and the ratio between them is more than 25~35.
