Surface contact structure cable wire

The utility model relates to a new GS8T31 steel wire rope with a surface contact structure, which is twisted by a metal rope core (1) and eight outer strands 1T*31SW (2) in one time, the metal rope core in the steel wire is formed by a 1*7, 1*25Fi, 1*26SW point contact or line contact structure metal strand core (3), a plurality of 1*26 SW line contact or surface contact structure outer big strands (4) and a plurality of 1*3, 1*7 point contact structure outer filling small strands (5). The steel wire rope has merits of long service life, strong bearing capability, high endurance bending strength, good plasticity and anti wear property, and good shock resistance and destruction resistance capability, can used in all kinds of hoisting machinery and bridge crane in steel factory, can improve the service life, reduce product cost and enhance product efficiency.
