Wire Rope
Technical DataCommon Classification of Wire Rope6 x 7 Class Wire Rope: 6 Strands, 7 wires per strandThis construction is used where ropes and dragged over the ground or over rollers and resistance to wear abrasion are important factors. The wires are quite large and will stand a great deal or wear. The 6 x 7 is a stiff rope and needs sheaves and drums of large sizes. It will not stand bending stresses as ropes witha large number of wires.
6 x 19 Class Wire Rope: 6 Strands, nominally 19 main wire per strandThis class is most widely used and is found in its many variations thoughout nearly all industries. With its combination of flexibility and wear resistance, rope in this class can be suited to the specific needs of diverse kinds of machinery and equipment. The designation of 6 x 19 is only nominal as the number of wires per strand ranges from 15 to 26.
6 x 37 Class Wire Rope: 6 Strands, 37 wires per strandThe 6 x 37 class of wire rope is characterized by the relatively large number of wires used in each strand. Ropes of this class are among the most flexible available, but their resistance to abrasionis less than the 6 x 19 class. The designation of 6 x 37 is again only nominal as in the 6 x 19 class.
19 x 7 Rotation Resistant Wire RopeThe 19 x 7 rotation resistance rope consists of an inner layer of 6 strands of 7 wireseach, made left lang lay over a strand core, and an outer layer of 12 strands, eachof 7 wires, made in right regular lay. It is this combination of opposing lays which enables the rope to resist the tendency to rotate when in service.
How to Caliper Wire RopeRope diameters are determined by measuring the circle that just touches the extreme outer limits of the strands - that is, the greatest dimension that can be measured with a pair of parallel-jawed calipers or machinists caliper square. A mistake could be made by measuring the smaller dimensions.

The low values of rotation allow “TOWERSTRAND-35” to be used both in single-part line with swivel attachment at the hook, or in multi-part line where the swivel may be considered as a convenience rather than a necessity.Crush ResistanceThe high steel content available for “TOWERSTRAND-35” provides good resistance to crushingon multi-strand layer drums. At the same time the design gives excellent flexibility so that spool-ing to low D:d ratios creates no problem.Bend Fatigue ResistanceThe selection of D:d ratios exceeding 14:1 create substantial improvemend in bend fatigue. Sim-ilarly appropriate service lubrication may substantially enhance cycle life.
