Abstract

The utility model discloses an all-steel cord for a giant engineering machinery radial tire belted layer. The all-steel cord is formed by weaving and twisting steel wire strands, wherein six outer-layer steel wire strands are woven and twisted around a core strand. Thus, the all-steel cord with a round section is formed. The outer-layer steel wire strands and the core stand are formed by weaving and twisting twelve outer-layer steel wires and six inner-layer steel wires around a core wire, and the steel wire strands with the orthohexagonal sections are formed. The all-steel cord facilitates permeation of rubber and improves the anti-corrosion performance, the bonding performance and the bonding retentivity of a tire, is high in strength and rigidity, prolongs the service life of the tire, reduces processing steps, and reduces production cost.
