MIL-DTL-83140B
for a left-hand lay, the wires or strands are in the opposite direction.
6.4.2.1 Lang lay. A wire rope in which both the wires in the strand and the strands in the
wire rope are laid in the same direction is designated as lang lay.
6.4.2.2 Regular lay. A wire rope in which the wires in the strand are laid in one direction
and the strands in the wire rope are laid in the opposite direction is designated as regular lay.
6.4.2.3 Length of lay (also termed "lay length" or "pitch"). The distance, parallel to the
axis of the strand or wire rope, in which a wire or strand makes one complete turn about the axis
is designated as the pitch (or length of lay) of the strand or wire rope.
6.4.3 Minimum breaking strength. The minimum tensile load that a wire rope must
support without breaking.
6.4.4 Ping. Ping is an audible sound given off as a result of an individual wire breaking
in the wire rope. The sound is amplified and fed into a speaker system to a level distinctly
detectable by the human ear.
6.4.5 Preformed type. Wire rope consisting of wires and strands shaped prior to
fabrication of the wire rope to conform to the form or curvature that they take in the finished
wire rope. Preformed wire ropes are wire ropes in which the wires and strands in the wire rope
will not, after removal of any seizing (serving) or when cut, spring out of the wire rope
formation.
6.4.6 Rotation-resistant (also termed "nonrotating" or "low torque"). A rotation-resistant
wire rope is a wire rope that resists turning or producing torque when placed under load.
6.4.7 Seizing. Single wires or strands used for making a close-wound helical serving, or
wrapped binding, to retain the wires and strands of a wire rope in their assembled position.
When cutting wire rope, seizing is applied to both sides of the cut location before the cut is
made.
6.4.8 Strand. Each group of wires helically twisted or laid together is designated as a
strand.
6.4.8.1 Strand center. A strand center consists of a single straight strand made of
preformed wires, similar to the other strands comprising the wire rope in arrangement and
number of wires.
6.4.9 Wire. Each individual cylindrical steel rod or thread is designated as a wire.
6.4.9.1 Center wire. The center of all strands is an individual wire and is designated as a
center wire.
6.4.10 Wire rope. A group of strands helically twisted or laid about a central core is
designated as a wire rope. The strands and the core act as a unit.
