FIELD: transport.

SUBSTANCE: invention concerns cable threads used to reinforce rib protective coating or/and to form reinforce element for pneumatic tires for industrial machinery of type Poids-lourd. Invention also relates composite fabric used as rib protective coats or/and as reinforce element for pneumatic tires. Cable thread contains three spiral strands, twisted in one integral system with lead p2, each of them includes two metal wires twisted in spiral in integrated system with pace p1. Wire diameters for specified strands are (d1, d2), (d1', d2'), (d1", d2") correspondingly, when this cable threads meet plurality of following consumptions: (i) 0.25 < d1 < 0.45; (ii) 0.25 < d2 < 0.45; (iii) 0.25 < d1' < 0.45; (iv) 0.25 < d2' < 0.45; (v) 0.25 < d1" < 0.45; (vi) 0.25 < d2" < 0.45 and (vii) 2 < p1 < p2 < 10.

EFFECT: improvement of endurance.
