What are the classifications of wire ropes?

1. According to the section shape of steel wire rope / cable, there are round steel wire rope and flat steel wire rope.

2. According to the section shape of steel wire rope strand, there are round strand and irregular strand, which can be divided into triangular strand and flat strand.

3. According to the steel wire rope, the contact state of each layer of steel wire in the steel strand is divided into point contact steel wire rope and line contact steel wire rope (including point line contact steel wire rope).

4. According to the section shape of steel wire, it can be divided into steel wire rope made of round steel wire and steel wire rope made of special-shaped steel wire (such as sealed steel wire rope).

According to the surface condition of steel wire, it is divided into smooth steel wire and galvanized steel wire. According to the mechanical properties of steel wire, it is divided into special steel wire and No. 1 steel wire.

5. According to the number of steel wire rope strands, they are divided into: single strand, six strand, eight strand, twelve strand, eighteen strand, thirty-four strand, etc. Top three / kroc-3 / from one

Layer strand composition; Twelve strand and eighteen strand steel wire ropes are composed of two layers of strands; And 34 strand wire rope, also known as non rotating wire rope.

6. According to the twisting direction and method of steel wire rope: twist left and right according to the twisting direction of strand; Pressing wire rope torsion method 1 - alternating torsion (reverse torsion) and same direction torsion (forward torsion).

7. Grading by strength: the steel wire rope is divided into several grades according to the nominal strength of the single wire. Different countries have different rating standards, such as circular stocks in China

The abnormal strand wire rope in Japan is 140155170185200 (kg / mm2), while the round strand wire rope in Japan is 135150165180 (kg / mm2), and the round strand wire rope in Germany.

8. Classification by purpose:

(1) General purpose steel wire rope (including steel strand);

(2) Elevator wire rope;

(3) Aviation wire rope;

(4) Steel wire rope of deep well drilling equipment;

(5) Steel wire rope for aerial ropeway and cable car;

(6) Hoisting wire rope;

(7) Steel strand for prestressed concrete;

(8) Fishing wire rope;

(9) Mining and hoisting wire rope;

(10) Steel cord for tire;

(11) Tape and wire rope.

(12) Slope protection net, hook net of protective net, and wire rope net made of wire rope.
