Steel Wire Rope

Dear Readers,

Let us discuss about the steel wire rope and classifications. Wire ropes are used in construction for handling of materials. Generally in construction 6 x 19 ropes are used. Centre core may by FC (Fibre Core) or SC (Steel Core)

 

In a numerical classification of rope construction, the first number is the number of strands; the second number is the number of wires in each strand. Thus, 6 x 25 means the wire rope has six individual strands with each strand containing 25 wires.

 

When such numbers are used as designations of standard wire rope classes, the second figure is purely nominal, in that the number of wires per strand for various ropes in the class may be slightly less or more than nominal.

 

For ropes with a wire strand core (WSC), a second group of numbers may be used to indicate the construction of the wire core, such as 1 x 21, 1 x 43 etc.

The standard construction of wire rope falls into four general classifications are 6 x 7, 6 x 19, 6 x 37, and 8 x 19. The first three ropes each contain six strands. In the fourth, each rope contains eight strands. The construction of a steel wire rope is expressed according to the following:

Example: 6x36-FC

     6 is the number of strands in the steel wire rope

     36 is the number of wires in the strand

     FC is the type of the core
