STEEL ROPE AND METHOD OF MANUFACTURING THEREOF Russian patent published in 2024 - IPC D07B1/10 

FIELD: ropes or cables of general purpose.

SUBSTANCE: invention relates to cable production and can be used in lifting equipment. Disclosed double-lay steel rope consists of one central strand, around which two layers of strands are twisted, wherein the strands of the inner layer have the same diameter D₂ and forming a metal core with the central strand, the strands of the outer layer of the rope are made with two different diameters D₃ and D₄, alternating with each other, wherein rope strands are plastically deformed with reduction of (4–6)%, then, simultaneously, all the strands are twisted into a rope in one technological operation, ensuring linear contact between the strands of the inner and outer layers of the rope.

EFFECT: obtaining a steel flexible rope with improved operational properties, with high structural density, high breaking force, low structural and elastic elongation.
