The invention provides a suspension bridge main cable strand manufacturing process and a suspension bridge main cable strand manufacturing system and belongs to the field of engineering equipment. Thesuspension bridge main cable strand manufacturing process comprises the steps of cutting off a steel wire, which is used for manufacturing a suspension bridge main cable strand and wound on a turntable, into more than two sections of steel wires; marking the steel wires; at the marked parts of the steel wires, dividing the steel wires into a plurality of areas to be shaped; conveying the plurality of steel wires to the ending end of an operation platform from the starting end of the operation platform; and in the steel wire conveying process, shaping the plurality of steel wires in the areasto be shaped, which are between the adjacent marked parts, into regular polygonal structures with different sections. A fixture comprises the operation platform, a square fixture and a regular hexagonal fixture; and the square fixture and the regular hexagonal fixture are respectively mounted on the operation platform. According to the suspension bridge main cable strand manufacturing process, byshaping the cable strand in advance in the machining and manufacturing stage in factories, accurate mounting position is guaranteed and the accuracy satisfies construction requirements, the shaping procedure on construction site is reduced and the lowering of the quality of the cable strand caused by site shaping is avoided.
