The 6x19 classification ropes shall contain 6 strands that are made up of 15
through 26 wires, of which no more than 12 are outside wires fabricated in one
operation. See Tables 4-15 and 4-17 and Figures 438 to 4-43.
The 6x37 classification ropes shall contain six strands that are made up of
27 through 49 wires, of which no more than 18 are outside wires fabricated in
one operation. See Tables 4-15 and 4-18 and Figures 4-44 to 4-51.
The 6x61 classification ropes shall contain six strands that are made up of
50 through 74 wires, of which no more than 24 are outside wires fabricated in
one operation. See Table 4-19 and Figures 4-52 and 4-53.
The 6x91 classification wire rope shall have six strands that are made up of
75 through 109 wires, of which no more than 30 are outside wires fabricated
in one operation. See Table 4-20 and Figures 4-54 and 4-55.
The 8x19 classification wire rope shall have eight strands that are made up
of 15 through 26 wires, of which no more than 12 are outside wires fabricated
in one operation. See Table 4-21 and Figures 4-56 and 4-57.
The 18x7 and 19x7 wire rope shall contain 18 or 19 strands, respectively. Each
strand is made up of seven wires. It is manufactured counterhelically laying an
outer 12-strand layer over an inner 6x7 or 7x7 wire rope. This produces a rotationresistant
characteristic. See Tables 4-16 and 4-22 and Figures 4-58 and 4-59.
The 6x25 “B,” 6x27 “H,” 6x30 “G,” and 6x31 “V” flattened strand wire rope
shall have six strands with 24 wires fabricated in two operations around a
semitriangular shaped core. See Table 4-23 and Figures 4-60 to 4-63.
In the manufacture of uniform-diameter wire rope, wires shall be continuous.
If joints are necessary in individual wires, they shall be made, prior to fabrication
