How Many Typs Of Steel Wire Ropes

- Aug 24, 2017 -

1,by structure:

(1) single twist (strand) wire rope: 1 ordinary single wire rope: by one or more layers of round steel wire spiral wound in a core twisted from the wire rope;

2 semi-sealed steel wire rope: the center of the wire around the spiral wound one or more round wire, in the outer layer is made of special-shaped wire and round wire twisted from the wire rope;

3 sealed steel wire rope: the center of the wire around the spiral wound one or more round wire, the outside by a layer or layers of special-shaped wire twisted from the wire rope

(2) double twist (multi-strand) wire rope: by one or more layers of a rope around the spiral was twisted from the single-layer multi-strand or multi-layer wire rope

(3) three twist wire rope (cable): multiple multi-strand wire rope around a fiber core or rope twisted from the wire rope

2, according to the diameter points: (1) fine diameter wire rope, that is, diameter <8mm wire rope

(2) ordinary diameter wire rope, that is, diameter ≥ 8 ~ 60mm wire rope

(3) thick diameter wire rope, that is, diameter> 60mm wire rope

(3) Steel wire rope for electric shovel (7) Strand for prestressed concrete (8) Wire rope for fishing (9) Wire rope for lifting wire (10) Steel cord for tire (11) Wire rope for tape

4, according to the surface state points: (1) smooth steel wire rope (2) galvanized steel wire rope (3) coated steel wire rope

5, according to the shape of the cross section: (1) round wire rope (2) shaped steel wire rope

6, according to twist characteristics: (1) point contact wire rope (2) line contact wire rope (3) surface contact wire rope

7, according to twist method points: right twist twist, left twist twist, right with the twist and left twist four

8, according to the rope core points: (1) fiber core - the application of natural fibers (such as sisal, cotton yarn), synthetic fibers and other performance requirements of the fiber made of (2) steel core (also known as metal core) Steel wire core and wire core.
