Steel wire rope construction is 6 x 37S + FC: .6x37 that the wire rope is composed of 6 strands, each strand has 37 steel wire; S that each wire thickness is different, each layer of steel wire arranged by thickness; FC that the wire rope is fiber core; linear contact is mainly thick and thin wire arrangement, increase the contact between the steel wire and the steel wire, the steel wire is a round strand.
Surface contact is mainly steel wire is not round strand steel wire, but shaped such as trapezoidal, oval, etc., steel wire and steel wire full contact to increase the abrasion resistance, mostly for the non-rotating steel wire rope, mainly used in vertical shaft lifting, high-altitude lifting. The market is generally point contact rope, 6x37 or 6x19 , strength of 1670 level. According to the use of different occasions, the use of different structures, different strength of the wire rope.
Type specification of wire rope:
The structure of the wire rope, such as 6X36WS+FC, 18X7+FC, 35WX7, etc.; the diameter of the wire rope, such as 18mm, 20mm, etc.; the nominal tensile strength of the wire rope, such as 1770MPa, 1960MPa; the surface state of the steel wire, such as galvanized is A grade, AB grade, B grade, glossy, etc..
Wire rope oiling situation, what kind of oil, etc.; wire rope implementation of the standard; length, twist direction, etc..
